Traditional medicine is an applied science that helps to maintain and restore health by prevention and treatment of illness in human beings. Nevertheless, nutrition and fitness emerged as supporting health processes in human beings through strengthening basic processes and the immune systems in human beings.

🛑 Fridays for Future – Global Climate Demonstrations.

Employees at Uppsala University UU, and the Swedish University of Agricultural Sciences SLU, joining the Global Climate Demonstration today Friday 24 September at Forumtorget in Uppsala around 15.30.

This is to show the leadership of UU and SLU their concern about the climate crisis, and to demand immediate action against the climate change. Universities need to show in practical terms and measures that they takes science seriously NOW, and they need to lead not only by examples but by actions as well.

Emergency Action to Restore Biodiversity and Protect Health from Global Environment Crisis

Indeed, it is not only about climate change anymore it is rather about a much wider large-scale and long-term Environmental crisis with unpredictable and irreversible impacts on biodiversity in general and the global health of humans in particular.

The combined effects and consequences of the ongoing degradation in biosphere, hydrosphere and atmosphere on biodiversity and human health would create severe health threats for all life forms on planet Earth. These degradation are brought about by environmental (e.g. pollution and waste) and climate change because of green-house gases specially carbon-dioxide. There are already signs of such effects but not yet understood and systematically researched. Such wicked and complex problems are new in science in general and medical ones in particular, They can’t, and will not, be cured by medical treatments and far beyond human capabilities to deal with even if the multilayered unknowns will be known. The functioning and metabolism in our bodies depends very strongly on the environmental conditions including the temperature. This wasn’t known for Darwin.

The UN General Assembly in September 2021 will bring countries together to meet again at the biodiversity summit in Kunming, China, and the climate conference (COP26) in Glasgow, UK. This time is about the serious situation what concerns the risks to health of increases above 1.5°C, which are now well established. The call in this post is stating that “Indeed, in the past 20 years, heat related mortality among people aged over 65 has increased by more than 50%. Among other things higher temperatures will bring about increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality. Harms disproportionately affect the most vulnerable, including children, older populations, ethnic minorities, poorer communities, and those with underlying health problems”.

Editorial Board of BMJ for emergency action to limit global temperature increase, restore biodiversity, and protect health (https://www.bmj.com/content/374/bmj.n1734). As stated in this article “Health professionals are united with environmental scientists, businesses, and many others in rejecting that this outcome is inevitable. More can and must be done now—in Glasgow and Kunming—and in the immediate years that follow. We join health professionals worldwide who have already supported calls for rapid action.”

Though the current attention ⚠️ is focused on climate change we have to take in consideration many other large-scale and long-term threats that are associated with the increasing environmental degradation from pollution and waste. This calls wider actions to promote and implements the UN-SDGs.

The COVID Pandemic – Safety-Security Micro- and Macro- Imperatives and the UN-SDGs.

Is the COVID pandemic over? Do we have validated and clear global answers? The vaccinations were expected to solve everything but this isn’t the case anymore and we understand that vaccines are not enough (https://www.google.se/amp/s/www.nytimes.com/2021/08/18/world/middleeast/israel-virus-infections-booster.amp.html).

Recent surges in Covid-19 cases due to the delta variant are reigniting discussion on return-to-work. With Apple and Alphabet, for example, postponing return-to-work plans until October. In this context, other companies and employees are reevaluating whether they want to return to the office. If so, how to maximise safety and security issues for their employees and the rest of society in general. For example, the return to in-person work on a trial basis can be a solution and many companies like Apple and Google are designing hybrid work solutions and models with shortened work week rather than a full five-day week, though the resilience in each company’s hybrid model does vary (https://www.google.se/amp/s/www.cnbc.com/amp/2021/08/01/why-youll-want-to-be-back-in-office-eventually-behavior-expert-.html?client=safari).

Even with the social nature of human beings will lead more workers to see the benefits of being in a workplace again. This isn’t the case for everyone and outdated standards of one-size-fits-all that still characterise conservative and traditional business-as-usual strategies need to be re-evaluated. This is, as health and safety concerns are likely to continue and will still make many employees resistant to work in office. So, employers may need to offer “trial basis” returns as a first step and to assess and quantify the large-scale and long-term outcome on equal foot as short-term and small-scale versions, of whatever the solutions or models they may use.

With the existing cloudy situation new questions and recommendations are emerging. Do we always need offices? (https://www.americanexpress.com/en-us/business/trends-and-insights/articles/is-an-office-necessary-1/). Indeed, many traditions need to be revisited, e.g. for what? when? also why? do we need offices? Do we really use, practice and benefit from ICT technology optimally? By the end of the twenty century they were many promises and expectations that ICT would give more resilience in working and allow people to be less dependent on offices. But, many of these promises and expectations became more and more volatile though the huge expansion of ICT ‘Information Communication Technology’, automation as well as the accelerating use of AI ‘Artificial Intelligence’ and ML ‘Machine Learning’. Also with the existing enormous needs to mitigate climate change and environment degradation as well as improve the life-quality in general (UN-SDGs). No question, transport and traffic issues can cause unnecessary stress, cost and inconveniences as well as more emissions of green house gases and pollution (sustain-earth.com). As an example, what regards gender and life-quality return to work it is harder for women (https://www.cnbc.com/2021/07/08/nobel-winning-poverty-researcher-on-why-people-wont-go-back-to-work-.html). As people attempt to return to work, child care costs burden women more than men. Jobs don’t offer flexible options and don’t pay enough to cover child care costs. Do we afford to put future generations at more risk? Therefore, women are likely to stay home and not because they don’t want to return to work. COVID has allowed us to know more about the roots of poverty, gender and social inequalities.

Even with the new trends of trial basis and hybrid solutions there are still recommendations of what employers need to reconsider and what employees need to demand in their work places (https://edition.cnn.com/interactive/2020/health/reopening-coronavirus/work.html). Among these it is required to know to which extent have coronavirus safety precautions changed in workplaces; What safety measures would be needed for workers in all settings?; Which types of employers and businesses might see the biggest changes right now?; What steps can workers take to keep themselves safe at work? What steps they should take when they get home?; What safety advices for people commuting and what employers can do for them?.

World Data – VACCINE ISN’T A GUARANTEE AGAINST A NEW SURGE IN COVID CASES⁉️, THE FOURTH WAVE IS A THREAT ⁉️.

The vaccination dilemma continues to emerge as worldwide data with somewhat, but not yet enough, increased statistical validity are becoming widely available (http://knoema.com/infographics/vzmsqj/covid-19-vaccine-effectiveness-in-data-over-120-countries-at-risk-for-new-covid-spikes). There are several key issues in this respect on the global, regional and country/local levels. The global and regional levels are dealt with primarily by the WHO. Though its considerable value in assessing the global data and monitoring the global trends of infection and its spreading, it has limited economic potential to influence the worldwide vaccination. This is part of great global discrepancies in the vaccination rates and frequencies. This creates huge constraints in the global health issues, in particular to achieve the UN-SDGs what regards health, education and poverty. There are no other worldwide organisations that have either economic capacity or economic responsibility to raise the vaccination rates on the global scale.

So, we still have an ongoing global dialogue about who will be vaccinated and who will get a boost of a third shot of vaccine (https://www.nbcnews.com/think/opinion/covid-vaccine-booster-shots-delta-variant-are-being-over-hyped-ncna1275507). This adds new dimensions to how to handle the vaccination resources on the global scale. There are several reasons for the existing cloudy situation of the vaccination what regards its effectiveness, accessibility and availability. The Pfizer shot, for example, was only 39 percent effective in preventing symptomatic Covid infection from late June to mid-July, a nosedive from levels seen this winter and early spring. Though this observation is based on small group and covered narrow window of time, it has however triggered the needs for offering a booster of a third shot to people over 60 who were vaccinated more than five months ago. According to different sources the delta variant is more contagious and likely more severe than its predecessors, this has also raised prompt discussions on whether booster shots can stem them and once again restore the impenetrable immunity of vaccinated people.

The global penetration of vaccination is still a serious problem as some countries are almost ready with the vaccination of their overall populations while others have very low vaccination rates with only few percent of the total population are vaccinated. On the other hand countries with very high vaccination rates of 80% have more or less the same spreading rates of COVID as the countries with very small vaccination rates. This raises new worries that vaccines are not a guarantee against further surge in COVID cases and thereby additional risks for development of new mutations. For example, European countries where cases are increasing serve as a reminder that vaccination progress is not a guarantee against a new surge in COVID cases even in other parts of the world.

We still are getting new data about the efficiency of vaccines, for example moderna claims that their COVID-vaccine booster produces more robust response against the delta variant (https://www.cnbc.com/2021/08/05/moderna-covid-vaccine-booster-produces-robust-response-against-delta.html). Data from different countries that used different vaccines, e.g. from China, also suggest that we still have little, or not enough, knowledge on the global effectiveness of vaccines specially what regards their long-term and large-scale behaviour with consideration to all the parameters involved in assessing the wicked issues COVID spreading in relation to vaccination and opening of economies.

Violation of Work Environment and Code-of-Conduct also at Highly Ranked Universities

Statistics and reports don’t emanate from nowhere and it is true that ’no smoke without fire’. For many years, universities have been acting as closed clubs with their own internal rules for assessment and evaluation. The mis-trust in the performance of universities has been growing for many years because of their failure to solve population and society needs. More remarkably is to update their systems to help young people to find jobs and to meet future challenges. The universities are more internally focused on how to survive and their staff are busy searching for funds and own promotion. Gradually they are increasingly isolated from both the society and population needs, as it is clear from failing to integrate the UN-SDGs in their activities.

Nature (one of the world’s most cited scientific journals) has published several reports about the malfunctioning at universities. For example the infected work environments with many cases of victimised colleagues, e.g. Lund Univesity in Sweden (https://www.nature.com/articles/d41586-021-01621-8); Max Planck Institute of Garching in Germany (https://www.nature.com/articles/d41586-018-05634-8, https://www.nature.com/articles/d41586-018-05668-y).

There are also many other examples of unhealthy working conditions at our universities. A global study highlights long hours, poor job security and mental-health struggles. This study (https://www.nature.com/articles/d41586-020-00101-9) involved more than 4,000 scientists who has painted a damning picture of the culture in which they work, suggesting that highly competitive and often hostile environments are damaging the quality of research and education. This is specially true among young Ph.D. students (https://www.nature.com/articles/d41586-019-03459-7) where they expressed the widespread and deep-seated frustrations with training, work–life balance, incidents of bullying and harassment, and cloudy job prospects (see ‘Free thinking’). This survey also included new questions suggested by early-career researchers, including ones on student debt, bullying and harassment, and career responsibilities. A question about mental health — asked of all respondents for the first time — shed light on some of the more troubling effects of higher education.

Some funding organisations (https://www.nature.com/articles/d41586-018-05071-7) started to take serious steps for cracking down on harassment and bullying. Scientists who have been sanctioned by their institutions could lose out on funding from e.g. the Wellcome Trust in the U.K., one of the world’s largest research-funding charities. Another funding organization, in the U.K. ‘The Leverhulme Trust’, has revoked a £1-million (US$1.3-million) grant from prominent palaeontologist who was also disciplined by his institution, the University of Bath, UK, after an investigation found he had breached its anti-harassment policy (https://www.nature.com/articles/d41586-018-06764-9). An elite US science academy expels a well-known astronomer following harassment complaints (https://www.nature.com/articles/d41586-021-01461-6). This is the first time the National Academy of Sciences has kicked out a member for violating its amended code of conduct. It is clear that they are much lack of actions by strategic funding organisations and well-ranked universities around the world to follow the example of the U.K. and the U.S.

It is also documented that sexual harassment is rife in the science (https://www.nature.com/articles/d41586-018-05404-6). Existing policies to address the issue are ineffective, concludes a long-awaited report from the National Academies of Sciences, Engineering, and Medicine. The NAS ‘the U.S. national academy of science’ told Nature that no one has used the complaint system put in place last year, even though several academy members are known sexual harassers. It is unfortunate that we let negative and destructive attitudes, what regards gender issues in general, to exist in our academic environment (https://www.nature.com/articles/d41586-020-02640-7).

Enough is enough, we know what are the problems but we still don’t know yet how to cope with the corruption, abuse of public resources and how to improve the working environment at universities and our academies. With increasing globalisation and mobility of young academics and qualified professionals in the global landscape of science there are still huge needs to re-examine the existing multi-layered structural defects and obstacles to achieve sustainable/healthy working environments. Higher education should not be part of the piling-up social injustice and ought to demonstrate good leadership in the global journey for prosperity.

COVID-19 Vaccins are here – Success Story to Defeat Our Common Enemy ‘COVID-19’

The worldwide endeavours and efforts to create safe, effective, accessible and affordable COVID-19 vaccines are beginning to bear fruits and to demonstrate the very beginning of the end to defeat COVID-19 and save the life of humans on Earth. 2020 is now ending by a remarkable achievement and success as 2020 will be remembered as one of worst years in human history for the past centuries, if not more. A handful of vaccines have been authorized around the globe; many more remain in development. Here you can follow the advances in the global landscape of vaccines (https://www.raps.org/news-and-articles/news-articles/2020/3/covid-19-vaccine-tracker). Other detailed information on development of COVID-19 candidate landscape are also complied in the WHO database (https://www.who.int/publications/m/item/draft-landscape-of-covid-19-candidate-vaccines).

The biggest vaccination campaign in modern history has begun. This is a remarkable event and a major milestone in modern history that brings happiness and relief for the global citizens as more than 4.2 million doses in seven countries have been administered, according to data collected by Bloomberg. Delivering billions more will be one of the greatest logistical challenges ever undertaken in human history (https://www.bloomberg.com/graphics/covid-vaccine-tracker-global-distribution/).

Advances in science and technology have always demonstrated enormous capabilities to save humans from common threats as in many other cases in human history. The boundaries between science fiction and technological realities are now vanishing very very fast and the 21st century can be a turning point for more and more common solutions to bring resilience and prosperity as long as politics (https://en.m.wikipedia.org/wiki/Politics) and political well act hand in hand with science and technology. ICT and IOT can bring together the global efforts and endeavours in sustainable tracks of success by decreasing ‘top-bottom and bottom-top’ communication gaps. COVID-19 has indeed showed how humanity can join together and unify to defeat common threats.

By the end of 2020, sustain-earth.com wishes all of us a Happy soon coming 2021.

Part II of the ‘Sustainability in Science and Technology’ – The Human Performance.

The performance of humans is driven by diverse needs for food and security to overcome the challenges for decent live on Earth. 

This is an introduction to Part Two of the WEBINARS on “Sustainability in Science and Technology” – The Performance of humans’, hosted by sustain-earth.com.

Africa is the origin of homo sapiens and the renewables helped their evolution during millions of years and their migration out of Africa 70 000 years ago.

During the hunting gatherer era humans started to master artefacts and simple tools, also to build small communities and settlements. They domesticated animals, plants and learned to cultivate land and build shelters for their living.

The agricultural era that started 10 000 years ago culminated in an outstanding ancient Egyptian civilisation that lasted 3000 years. During this era people used water to promote agriculture, farming and to produce food. These achievements were made possible by taking advantages of renewable resources only, the sun (heat and light), water from the Nile and limited use of natural resources.

The mechanisation of agriculture in the 18th century during the first industrial revolution triggered increasing use of artificial pesticides and fertilisers. However, the limited water resources on Earth caused new needs for diversification of water production and management in order to have clean, affordable and accessible water for the growing population and the increasing urbanisation. The first industrial revolution involved various manufacturing processes supported by water and steam power.

The second industrial revolution in Britain was based on increasing electrification and use of combustion engines, rapid standardisation and industrialisation of many sectors in the 19th and 20th centuries. The widespread developments of the first and second industrial revolutions created huge pollution and waste in the atmosphere, the hydrosphere and the biosphere that continued and continued until now. New but limited renewable technologies, however, with zero net emission of green house gases started to appear by the end of the 20th century. This was due to the fear that fossil fuels are limited and have negative impacts on life. These developments were possible by more affordable access to renewable energies and the expanding use of alternating and direct current motors. Indeed, there are still several environmental challenges for scaling-up and scaling-out the renewables. Among these are the storage of renewables and integrating them in well-established grids. However, renewables and batteries require needs for new materials and further expansion of mining and processing that are dependent on heavy consumption of water and energy.

The third industrial revolution of digitalisation started by the end of the 20th century and opened new possibilities for increasing efficiencies and volumes of communication not only between humans but also between humans and machines, and between machines and machines as well.

The Information-Communication-Technologies and the Internet of Things will allow extensive and intensive expansion of Science and Technology with new gates for innovation worldwide on all levels and in many sectors. We have now many examples around the world which demonstrate that the boundaries between science fiction and technological realities are vanishing very very fast. We are, now, in urgent needs to proceed with the 4th industrial revolution and to continue with Artificial Intelligence and Machine Learning but with careful attention to the demands of renewables, preservation and protection of life.

Pre-announcement for Forthcoming WEBINARS 2021: Sustainability in Science and Technology.

The WEBINARS on Sustainability in Science and Technology will be hosted by sustain-earth.com. and will appear in 2021. They are coordinated by Professor em Farid El-Daoushy (Uppsala University, Sweden) and will be given by many professionals and professors from around the world. It is based on trans-disciplinary and trans-sectoral approaches to explain and detail several patio-temporal yet complex, wicked and interactive problems that piled-up over very long periods of time and caused the evolution of a new geologic era, i.e. the so-called anthropocene.

In part one, the natural drivers of life on planet earth, in the atmosphere, hydrosphere, biosphere and lithosphere, will be explained to give the necessary bases for understanding the boundary conditions of the natural climate and environment systems of the Earth. In part two the life-styles of humans ‘homo sapiens’ on planet since their evolution on Earth, and migration out of Africa 70 000 years ago, i.e. during different transitions and changes from the hanter gatherer era until now will be followed. Part three will give the impacts of the combined spatio-temporal interactions between human life and the planets’ own drivers on the global economic systems. Further part three will involve issues related to growth economy versus circular economy. In part four analysis of the performance of sustainability with reference to the first three parts will be done. In this context, resilience in human knowledge versus science, technology and innovation will be examined. These four parts together will give background information on ‘what, why and how’ what regards sustainability can be put together in a resilient framework to scale-up and scale-out science, technology and innovation to meet the UN-SDGs in order to achieve prosperity on planet Earth.

In summary the forthcoming WEBINARS can be described as follows:

Part One: The performance of planet Earth.

Part Two: The performance of humans ‘Homo Sapiens’.

Part Three: The performance of world economic systems with consideration to growth economy versus circular economy.

Part Four: The performance of sustainability. Resilience in knowledge versus science and technology.

Highly Recommended – All Our Food Is Nature Made. However ‘AI’ and ‘ML’ can Improve Food Industries.

Photosynthesis is the main reaction behind all life forms on planet Earth, it triggers life processes in global eco-systems on land and in aquatic systems (ocean, lakes and rivers). For photosynthesis to do its job and produce all forms of healthy and nutritious food that makes up global biodiversity, including us humans the ‘Homo Sapiens’ (https://en.m.wikipedia.org/wiki/Human) water is needed. Indeed, even if we say water is the origin of life, it isn’t totally 💯 correct as we still need carbon dioxide in trace amounts. An important question is high trace is trace? Even though we have water and carbon dioxide at the right concentration, we aren’t done yet, as we also need solar energy ‘light photons’ to initiate this magic reaction and the very secret of nature that evolved four billions of years ago, the ‘photosynthesis’.

There are many other imperatives that are needed for the natural photosynthesis to do its job properly and to keep it in tact with all the functioning and metabolism processes of life forms on earth apart from the reactants, i.e. water, carbon dioxide and the photon from the sun. We need healthy atmosphere and healthy hydrosphere, these underlying spheres of life are currently undergoing continuous degradation by us humans. This indeed imposes great threat for the proper functioning and metabolism of the very basic mechanism that fuels the life on Earth, i.e. the photosynthesis.

The atmosphere is important for agricultural sectors and farming, apart from supporting the forest eco-systems. Naturally healthy and fertile soils, are also needed, that have the right mixture of nutrients and free from toxic chemical remains and heavy metals. Also, soils need to have good water holding capacity which is regulated by the organic content. For the atmosphere to be healthy environment for the photosynthesis to take place on land, we must have suitable atmospheric composition, e.g. carbon dioxide concentration that allows having appropriate temperature, in addition to being a necessary component for photosynthesis. Also, not to have toxic compounds in the atmosphere such as nitrogen oxides that through photo-reactions can produce boundary-layer ozone that has negative impacts on growth of vegetation, in particular forests.

What regards aquatic systems we still need suitable temperature (which is dependent also on the heat-balance in the atmosphere) in water bodies, suitable pH as acidification from acidic nitrogen- and sulphur-oxides destroys the living-habitats of fish such the corals in the ocean, also it destroys the food-web and kills fish as in fresh-water lakes and rivers; suitable amount and levels of oxygen for breathing is also imperative in aquatic systems. Naturally, we need also other trace nutrients in particular phosphorus, nitrogen and potassium (applies also for healthy vegetation on land and agricultural production). However, excess amount of nutrients cause eutrophication as the water bodies become overly enriched with minerals and nutrients which induce excessive growth of algae. This results in oxygen depletion in the water body after the bacterial degradation of the algae. As an example is the so-called ‘algal bloom’ or great increase of phytoplankton levels. Eutrophication is often induced by the discharge of nitrate or phosphate-compounds, fertilisers or sewage into aquatic systems.

We humans so far failed to imitate nature, i.e. to do what is known as ‘Artificial photosynthesis’ which still science fiction. Would we ever have Artificial Intelligence ‘AI’ to cultivate our earth, produce our food and create an Artificial Biodiversity? ‘AI’ can create robots and machines that imitate us humans in many ways through collecting the patterns of our behaviour. Robots can’t run the life on our planet itself but they can be better version of humans through Machine Learning ‘ML’ and thereby replace humans to do many many jobs in food industries, and also many other industries.

The implementation of AI and ML in food manufacturing and restaurant businesses is already moving our industry to a new level of performance, enabling fewer human errors, less waste of abundant products, less infections. They also allow lowering costs for storage, delivery and transportation. They can create happier customers through timely and quicker service. Even they can allow voice searching, more personalised and effective orders. Robotics for big factories and restaurant businesses will occupy its niche very soon and will bringing more benefits in the long run. Both AI and ML benefit from the enormous flora of sensors, actuators in addition to digital coding and programming.

Introduction – Part One: The Three Main Drivers of Life on Planet Earth “Energy, Water and Natural Resources”.

Introduction to the forthcoming WEBINARS, hosted by sustain-earth.com, on “Sustainability in Science, Technology and Innovation ’SISTI’ of Water, Energy and Natural Resources”. Part One of the introduction – The three main drivers of life on Earth: “Energy, Water and Natural Resources WENR”. These drivers, by being dependent on the main underlying and interactive sphere of the Earth System (atmosphere, hydrosphere, biosphere and lithosphere) are decisive for the performance and quality of both the life on planet Earth and the life of humans.

These three drivers ‘WENR’ have, so far, sustained all life forms on planet earth. Energy from the sun triggers photosynthesis where water in the HYDROSPHERE together with carbon dioxide in ATMOSPHERE have been the bases of all life in the BIOSPHERE both on land and in aquatic systems. Minor amounts of earth’s mineral resources in the upper LITHOSPHERE are also used as nutrients in the evolution of biodiversity and associated eco-services we benefit from as well as the production of our food. Homo Sapiens are not only part of the global biodiversity but they are becoming the main actor shaping it. Homo Sapiens extended the production. use and consumption of energy, water and the natural resources in the atmosphere (where oxygen is also crucial for life), hydrosphere, biosphere and lithosphere (including fossil minerals) for their living. The extensive and accelerating use of these drivers has surpassed the natural capacities and boundaries of planet earth to sustain all its life forms.

These drivers are imperative to achieve sustainable prosperity through integrated and resilient economic, environmental and social synergies. They involve trans-disciplinary and trans-sectorial (nexus) interactions in the socio-environment-economic fabrics that are shaping the future our planet including all societies around the world. Incorporating Environment-Social-Governace ‘ESG’ is fundamental for healthy and wealthy economies around the world.

Highly Recommended 💯 – Public Health Risks, The COVID-19 Can Spread by AC and Building Ventilation

Though the expectation of vaccine is around the corner, we still need to wait for at least few months. Meanwhile COVID-19 will not go away by itself and it will still be with us for sometime.

It is commonly known that COVID-19 can spread through aerosol droplets for quite some distant, get attached and accumulated on surfaces for time periods that allow them to circulation in buildings by ventilation and air-conditioning systems. Though there are risks and indications that AC and ventilation systems can cause spreading of COVID-19 there are still limited, systematic detailed and comprehensive studies on the exact effects of humidity, temperature and the technical specification of filters in large central ventilation and AC system. Through the so-called ‘Memory Effects’, e.g. in Offices, Towers, Restaurants, Hotels and similar Complex Buildings. In theory, it is enough that few infected persons can cause spreading of COVID-19 in the whole building if control, considerations and precautions are not well in place. Though out-door air can be used to some extent to mitigate this problem there are still several limitations. So, degraded indoors air-quality can in itself cause serious public health issues as we still don’t have enough knowledge. Even being tested negative isn’t enough to be safe in air-flights (https://www.google.se/amp/s/www.cnbc.com/amp/2020/10/14/travel-and-coronavirus-do-pre-flight-covid-19-tests-work.html).

We are facing the threats of a second wave that may very well be much aggressive and we need to be very careful about indoors air-quality. Air-quality is definitely a serious matter that requires good sanitation in air and also how to deal with it needs to call our attention.

Few observations, literature and research articles on this matters are given here.

Is Urbanization Done Right – COVID-19 and Greening of Cities

In the past decades we have observed an accelerating urbanization around the world where many old cities expanded enormously. Leaving little spaces for the citizens to move freely, to breath fresh-air, to exercise in natural environments and even be exposed to the sun. In many cities there are no affordable and easy access to parks, forests and green areas. Even more serious new cities in many parts of the world are built intentionally with increasing densification where living areas are designed to meet the needs of working adults, transport systems and cars as if recreation and children don’t exist.

All of us have definitely experienced the considerable degradation in the life-quality of our modern cities. They became parts of complex industrial production sites and we became part of complex machinery systems. Even with the invent and use of ICT we still over crowded in small areas, i.e. to be as productive as possible. In the early days of the ICT is was believed that people can be more flexible and resilient and not always forced to be in working places. However, business-as-usual became part of our life-style as if ICT doesn’t exist.

COVID-19 has drawn our attention to how urbanization and modern life-style brought with several negative impacts to life-quality. In many cities and urban areas around the world it is even hard to apply ‘physical distancing’ as there are no spaces to do so. Also, ‘stay at home’ isn’t a suitable practice as household may have many persons living in the same appartements and houses. Public transport systems, schools and public services can still be very crowded. Even the use of masks are not standard in many places or even not recommended or recognized as being a safe option. One can ask what options are left other than transmitting infections.

A city is more than its buildings and more than just housing. Modern densification is often about constructing as much housing as possible, as quickly as possible. Of course, considerations are great for housing but in the rush to build quickly it is important to slow down and ask ourselves: What kind of environments and life-style are we creating? Why and for whom are we building? How can we create cities and living environments that are sustainable, resilient and comfortable for everyone? Are our urban spaces contributing in a good built environment for pleasant life?

The Swedish National Board of Housing, Building and Planning has produced a
document in response to public debate on the densification of cities and communities, and to provide inspiration and guidance regarding ways to supplement the existing environment. Densification is not only about housing, it is about good built environment and life-quality for the people who live, work and spend time in the city. This publication gives views and arguments concerning some of the challenges and opportunities of densification. It also has interviews conducted with a few people about how they approach the challenges that exist. For example: how people’s needs for sunlight and daylight can be satisfied, how disturbing sounds in a dense city can be handled, how vegetation can be used as a resource, how room for public services can be created, and how a densification strategy for the entire city might be developed. It highlights a number of examples of municipal densification projects, all of which have added value over and above new housing. Mirja Ranesköld, planning architect, was the project leader and Elin Normann Bjarsell, landscape architect, was a member of the project team. Other coworkers contributed with their views and suggestions during the course of the project. The interviews were conducted by Elisabeth Klingberg at PratMinus (https://www.boverket.se/globalassets/publikationer/dokument/2017/urban-density-done-right.pdf).

Here some example of successful planning in the city of Gothenburg, Sweden, where I spent marvelous time in its ’Slottsskogens’ (https://www.goteborg.com/en/slottsskogen/) with an animal park, one of the oldest in Sweden. Just to demonstrate the old good times.

2020 – 24 Hours of Daily Reality Taking Place on Earth and Countdown to Uncertain Future

Interesting and scary reading that describes the daily reality around the world as experienced during 2020. What is going on planet Earth and the impacts of our irresponsible use of the global natural resources, in particular energy resources (by industry, transport, building and others), is based on scientific data and statistics specially what regards the atmospheric pollution. Among such impacts is the accelerating increase in the earth’s surface temperature (1880-2019).

What is happening in the atmosphere is triggering a global ‘Domino Effect’ with severe impacts on all other key spheres on Planet Earth. In particular the hydrosphere, the biosphere and ecosphere with tectonic threats on our living landscape (both rural and urban) and on daily basis. Global warming is also a medical emergency in times where COVID-19 pandemic makes the life more severe for many of us. The can be. connections between global warming and the COVID-19 pandemic. What is more serious is the scientific and technological advances, for many reasons, would not protect us against the consequences of global warming and will not bring back the decline in natural resources including loss of biodiversity. What is done is done and can’t be redone. As an example the CRISPR/Cas9 genetic scissor is unlikely to solve diseases caused by air and water pollution, also the mitigate the loss in biodiversity and tackle degradation in life-quality of atmosphere, bio and eco-sphere.

Sir David Attenborough and BBC for the Nobel Prize in Peace

The Nobel Prize for Peace (https://www.nobelprize.org/prizes/lists/all-nobel-peace-prizes/) has been awarded 100 times to 134 Nobel Laureates between 1901 and 2019, 107 individuals and 27 organizations. Among the International organizaions: Red Cross that got the Prize three times (in 1917, 1944 and 1963), the United Nations High Commissioner for Refugees got it two times (in 1954 and 1981), the Intergovernmental Panel on Climate Change (IPCC) and Albert Arnold (Al) Gore Jr. (2007), International Atomic Energy Agency (IAEA) and Mohamed ElBatadei (2005). These are some examples, in the same manner, we can argue that BBC and Sir David Attenborough would also be excellent candidates that deserve the Nobel Prize for Peace.

The world was just waiting for this incredible event of Sir David Attenborough to join the Instagram. It is just to use Instagram as amplifier for lifting-up biodiversity as an important part of ‘Life on Our Planet’. In just few days his Intagram Account went viral (https://instagram.com/davidattenborough?igshid=11ay0osmkukkp) with millions of followers and more to come. It is as he has an important message to us. The power of social media can hardly be ignored anymore even by highly educated professionals and politicians. What is more important is the content of social media channels that keep improving as more and more are becoming dependent on them and critical voices continue to add new dimensions as ‘survival of the fit’ is becoming an evolution and the norm for progress on the Internet. With the rise of the Internet (https://en.m.wikipedia.org/wiki/Internet) and the boom 🤯 of social media (https://en.m.wikipedia.org/wiki/Social_media) it is crucial to underline that quality of the content is being recognised more and more by the users. For a great portion of us, that can’t afford regular schooling and/or the expensive higher education, the social media channels are becoming an important source, if not the only source, of knowledge. Classical, conventional and international broadcasting channels (https://en.m.wikipedia.org/wiki/International_broadcasting) aren’t the only standard source of information and knowledge for many of us as they used to be. Though these trends, the global education systems, including higher education, are still closed systems as they don’t necessarily serve, i.e. the needs, the majority of the world population but rather an elite minority, as in football and other sports. Education, knowledge and knowledge transfer are imperative also as tools for public awareness, to share the responsibility, and not necessarily as a passport to the labor market that still support growth/linear economy. Universities and higher education institutes still lack efficient tools to reach out to the normal citizens, mediate knowledge and come near the society through tight engagement and active interactions. This is also the case for public education funded by taxes. Though the extreme importance of education institutes, in particular higher education, they still use ‘business-as-usual’ strategies without enough outreach policies to mediate and advocate knowledge to the public for protection and preservation of our common natural resources. This is the third duty of the universities and not only to perform pure ‘Research and Education’ that still can’t cope to solve existential problems as climate and environment changes, and the collapse in biodiversity, also to offer the necessary services to the citizens in major health disasters and pandemics as COVID-19. This is partly because universities and higher education continue to fail in creating partnership for goals neither with the citizens nor with the politicians as these are also part of their responsibilities, i.e. not to be isolated from the society and live on their own.

Sir David Attenborough and BBC achieved what the world universities failed to do, i.e. communicate science and technology in pedagogic and simple way, to inspire and motivate people, specially the young ones. To raise biodiversity as equally important, as climate change what regards our survival on planet Earth, is without hesitation an outcome of the work of Sir David Attenborough and through the systematic and continuous support of BBC (https://www.google.se/search?q=david+attenborough+nobel+prize&ie=UTF-8&oe=UTF-8&hl=sv-se&client=safari). This is why they are very well placed to be nominated for the Nobel Prize.

Recent Addition: Professor Torbjörn Ebenhard on the Editorial Board, Swedish University of Agricultural Sciences, Uppsala.

We are greatly honoured to have Professor Torbjörn Ebenhard on the Editorial Board of sustain-earth.com. Professor Torbjörn Ebenhard is the Deputy director of the Swedish Biodiversity Centre, Swedish University of Agricultural Sciences

Professor Ebenhard is a biologist with a B. Sc. degree from Uppsala University and a Ph. D. degree in zoological ecology from the same university. His early research was focused on island biogeography and conservation biology. Presently he is employed by the Swedish University of Agricultural Sciences, and based at its Swedish Biodiversity Centre (CBM). It is a special unit for research and communication on conservation, restoration and sustainable use of biodiversity as a crucial issue for society, especially as related to Sweden’s implementation of the UN Convention on Biological Diversity. Its mission is to initiate, conduct and coordinate policy-relevant research on the complex interactions between biodiversity and social development, and contribute to society’s capacity to manage these interactions in a sustainable way.

Apart from administrative tasks of Professor Ebenhard at CBM, he works on a number of assignments from the Swedish Environmental Protection Agency, supporting their activities on biological diversity in Sweden, and in international negotiations. Professor Ebenhard is mainly involved in the negotiations of the Convention on Biological Diversity (CBD) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), as a member of the Swedish national delegations. He is also member of the Scientific Council on Biological Diversity and Ecosystem Services at the SEPA, and serves on the board of WWF Sweden.

As explained by Professor Ebenhard “The recent Global Assessment Report on Biodiversity and Ecosystem Services produced by IPBES shows that the present and projected global loss of biodiversity jeopardizes our possibilities to reach the UN Sustainable Development Goals. Humanity is ultimately dependent on biodiversity for its wellbeing and survival. The food we eat, the clean water we drink, the clean air we breathe, fibres for clothing, wood for building homes, and bioenergy to replace fossil fuels – all is provided by biological diversity. But more is at stake. As we deplete the resources that could support us, we also annihilate living organisms and degrade natural ecosystems. According to the IPBES report at least 1 million species of animals and plants are now threatened with extinction. However, the IPBES report also gives hope, as it states that we can bend the curve of biodiversity loss, if we are determined to do so. What it takes is nothing less than a transformative change of the entire human society.”

Professor Ebenhard also reminds us that “Ten years ago the Convention on Biological Diversity (CBD), to which almost all countries are party, decided on a strategy and a set of global goals to conserve and sustainably use biodiversity, the so-called Aichi targets. They represent a high level of ambition, a much needed component of the transformative change IPBES envisages. CBD’s report Global Biodiversity Outlook 5, issued in September 2020, shows that none of the 20 Aichi targets will be met in full. This disappointing result, at a time when all targets should have been met, is due to a widespread inability by governments to implement the CBD strategy at the national level. Goals and targets at the national level have generally been set at a too low level of ambition, and national measures to reach these goals and targets have been insufficient. We do know, however, that when governments, as well as companies and individuals, have taken appropriate action, it does work, as shown by many successful cases of conservation and sustainable use around the world. But they are too few to bend the negative curve at global level.”

According to Professor Ebenhard “We now suffer the ravages of the covid-19 pandemic to our health and economy, while the growing climate crisis promises to make things much worse, but the looming biodiversity crisis will be of a completely different magnitude. The challenge now is to find integrated solutions, where the entire human society is involved in handling pandemics (there will be more than the present one), climate change and biodiversity loss. For this to happen we need people and decision makers to be aware of the nature of these crises, involve all stakeholders, set new ambitious strategies and goals for biodiversity and ecosystem services, strengthen national implementation and global cooperation, and work in a truly integrated way to address biodiversity loss, climate change and human wellbeing.”

New Addition – Editorial: Professor Anders Wörman. ‘KTH’ Royal Institute of Technology, Stockholm.

Professor Anders Wörman is the Head of division for Resources, Energy and Infrastructure, The Royal Institute of Technology, Stockholm (https://www.kth.se/profile/worman).

His research interest spans over wide-range of trans-disciplinary and trans-sectorial areas in engineering sciences and technology within water resources, hydrology and environmental hydraulics. Ongoing research are due to water and energy availability in terrestrial hydrology, effects of climate fluctuations and landscape changes on runoff, hydropower regulation, extreme flows in rivers and safety of embankment dams. His skill and expertise include: environmental impact assessment; water quality; water resources management; engineering, applied and computational mathematics; hydrological modeling; rivers; civil engineering, hydrologic and water resource modelling and simulation; water balance; waterfall runoff modelling; aquatic eco-systems; surface water geo-statistics; contaminant transport; groundwater penetration; radar and climate change impacts.

Professor Wörman was co-founder and the first manager of the undergraduate educational programme for Environmental and Aquatic Engineering at Uppsala Univ. before being chair prof. at KTH. KTH has dedicated research programmes in Applied Sustainability. One of such programmes is oriented towards finding customized solutions to develope sustainable and resilient technical applications that are climatically and environmentally suited for Africa (https://www.kth.se/en/om/internationellt/projekt/kth-in-africa/africa-1.619441). It is interesting to mention that the world longest river, the Nile, spans over large catchment areas that are located in different climatic/weather (spatio-temporal variability in temperature and precipitation) zones (http://atlas.nilebasin.org/treatise/nile-basin-climate-zones/). These special features of the Nile call for technologies that can cope with climate-environment changes of both natural and man-made origins. Combination of natural and man-made climate changes will certainly induce severe constraints and limitations on what, why and how ‘Water, Energy and Natural Resources (fossil and mineral deposits, eco-systems and biodiversity)’ Nexus need to be carefully accessed on long-term and large-scale bases. In this context, Prof. Wörman has trans-disciplinary and trans-sectorial knowledge suited to handle the complex, inextricable and multi-layered interactions within and between Water, Energy and Natural Resource Systems. These interactions are imperative to understand of coherent and resilient coupling with the Socio-Economic-Environment ‘SEE’ aspects in communities living in river-catchment systems in Africa. These issues are of special interest as river-systems are the dominant landscape units with huge importance for preservation and protection of renewable and fossil resources.

Editorial: What is Digital Water? Professor Bengt Carlsson, IT and System Control, Uppsala University explains.

We are delighted to have Professor Bengt, Carlsson at Department of Information Technology, Division of Systems and Control, Uppsala Univesity, on the Editorial Board of sustain-earth.com. As Prof. Bengt Carlsson put it in his words “Treating wastewater is great, but making the treatment resource-efficient is even greater”. Among the expertise of Professor Bengt Carlsson: energy efficiency; automatic control system identification; sustainable development; and wastewater engineering.

Sweden has been been a pioneer in water quality and water cleaning both what regards natural and urban waters. However, the digitalisation is now part of production, use and consumption of water worldwide as the pressure on water resources increased enormously and still accelerate. Here, we give an example on The UK Digital Water Utility Experience (https://youtu.be/V8DEAy3o0S8).

What are the greatest challenges for water and wastewater treatment today?
Some of the greatest challenges for water and wastewater treatment today is the contributions of pharmaceuticals that has increased pollution loads on environment. One challenge, is therefore, to effectively separate such residues in treatment plants and another is to cope with achieving climate-neutral wastewater treatment plants.

This post will be further updated and revised very soon.

Leasons Learned – Global Quality of Education and COVID-19: No Teacher or Student Be Left Behind?

The ‘ICT’ Information Communication Technology has enormous impacts and caused huge changes in our lives and on all levels, this is however specially true in the developed world. Meanwhile, the heterogeneity, what regards accessibility, affordability and diffusion of modem ICT, is still a worldwide issue. The majority of people in the developing world still suffer from serious inequalities which indeed sets major constraints in many life situations. In this context, the UN-SDGs, including targets therein, represent the intertwined relations and the increasing complexity of the socio-economic-environment aspects in modern societies. The UN-SDGs is an inter-connected package of interactive goals all of it have multi-layered dynamics with continuous and tight feedback impacts within and between each other. They have to be promoted and implemented in parallel and coherently, and above all to operate in phase with each other. Delayed effects in the function between and within the goals can have unprecedented consequences for major groups in societies as is presented here.

COVID-19 has clearly demonstrated, for example, how education is being severely affected in many countries (https://www.un.org/development/desa/dspd/wp-content/uploads/sites/22/2020/08/sg_policy_brief_covid-19_and_education_august_2020.pdf) where the teachers and students became incapable of performing their activities as in normal situations. Many indeed were left behind and still. During the course of the COVID-19 pandemic, the UNESCO came with initiative against the COVID-19 “NO TEACHER OR STUDENT SHOULD BE LEFT BEHIND” as proposed by the Chairperson of the Executive Board of UNESCO. As we didn’t have enough room for preparedness on how to meet the pandemic, the UNESCO initiative provided little solutions to promptly help the situation but it paved the way on how to tackle similar situation in the future, specially the second wave of the pandemic which already started in some countries. The impacts of COVID-19 are devastating to the fabrics of life, in general, as we know it, particularly on the education systems in the developing countries. According to UNESCO, some 107 countries implemented nationwide closures of schools by 18 March 2020, in response to the pandemic. This affected over 861.7 million children and youth, i.e. about 45 per cent of the global population of children and youth in schools or according to latest figures up to 78% of global population of school children and youth. Almost a whole generation in the developing world became at risk over night. In the coming second wave if this isn’t dealt with on time, this unprecedented situation could lead to the collapse of school systems in many developing countries as the local governments can’t cope with such enormous consequences of the virus.

The UNESCO initiative focuses specifically on providing a concrete, meaningful and timely response to the unprecedented crisis that the coronavirus is inflicting on the education system in the developing world.
Its objectives were/are: (1) to generate extra-budgetary funds from the World Bank, IMF, regional banks, governments, NGOs, public and private donors, and other voluntary supports; (2) to provide urgently needed funds to schools in developing nations in order to permit the payment of two to three months salaries to teachers; (3) to assist schools to adapt their working methods to enable students to pursue studies under confinement; (4) and to revalue the teaching system/profession in the developing countries (https://en.unesco.org/sites/default/files/no_teacher_or_student_should_be_left_behind.pdf).

As an example, we can see the case of South Africa and how the digital inequalities in e-learning, in their complex education system, has impacted pupils specially those who come from disadvantaged backgrounds, e.g. the rural communities. We can name some different reasons for the complexity, which also apply to many other countries in Africa. Language is one, most pupils don’t speak English, as a mother tongue while the official language dominating many classrooms is English. French, for example, is still a dominant language in other African countries while the population in general may have different mother tongues or dialects. Also, the effects of the virus have kept pupils and teachers at home. While e-learning is the solution, the reality in South Africa, as in most developing countries, is very different. Teachers have varying digital skills and many families and teachers cannot afford the systems necessary to sustain some online learning activities. COVID-19 has shown that technology is not anymore a luxury but rather an important component of the education process. However, we still define poverty in conventional ways ‘business-as-usual’ even in world organizations such as IMF (International Monetary Fund) and the WB (World Bank).

In presenting solutions, a wide range of factors must be considered. These range from access to computers, to teacher training, to the social and economic challenges faced by teachers, pupils and schools in their communities. Though Information and Communications Technology ‘ICT’ is taught as a school subject, the government needs to consider an additional range of issues to solidify its commitment towards e-learning. This includes policies and strategies surrounding connectivity, data costs, skills development, hardware access as well as contextual multilingual digital learning content. Many schools still have little or no technology facilities, e.g. tablets and advanced computing systems. Formal training in applied technical skills needs to be extended to all teachers. Adequate digital skills training should become a mandatory component of all teacher training programmes in universities, universities of technology and colleges. Another obstacle is the cost of data-transfer which is among the highest in Africa.This means that pupils can’t always easily access information on their mobile phones. In fact, when pupils and teachers receive the right support for digital learning, the response is often remarkable. Many teachers can willingly dedicate their weekends and school holidays to digital learning and teaching, with no financial incentives. There is also bright spots of collaboration between computing students from the University of the Western Cape with teachers in a high school in an underprivileged part of Cape Town. Their work together has cultivated computing skills and sparked learners’ interest in other subjects like chemistry and astronomy. To know more about the problems of e-learning under the constraints caused by COVID-19 in South Africa see this reference (https://theconversation.com/how-south-africa-can-address-digital-inequalities-in-e-learning-137086).

Nanotechnology inventions of the Ancient Civilisations

Historical texts from Spain, Italy, the Middle East and Egypt revealed how lustreware, pottery, batteries, steel swords and hair-dyeing were using nano-composites generating metal-glass and metal coatings on surfaces in different ways to produce impressive products of exceptional quality with enhanced material’s properties (https://www.theguardian.com/nanotechnology-world/nanotechnology-is-ancient-history). Damascus steel swords from the Middle East were made between AD300 and AD1700 with impressive strength, shatter resistance and exceptionally sharp cutting edge. The blades contained oriented nanoscale wire-and-tube-like structures with exceptional qualities. Pottery across the Renaissance Mediterranean was often decorated with an iridescent metallic glaze of colour and sheen down to nanoparticles of copper or silver.
Ancient Egyptian hair-dyeing, dating to the Graeco-Roman period, was shown to contain lead-sulphide nanocrystals of 5 nanometre diameter (https://neurophilosophy.wordpress.com/2006/09/06/the-ancient-egyptians-used-nanocosmetics/).

Though craftsmen were highly skilled to produce such materials that by modern definitions falls under nanotechnology they didn’t not know that they were working on the nanoscale. Such amazing inventions from ancient times dated back to thousands of years are numerous examples of ancient technology that leave us awe-struck at the knowledge and wisdom by the people of our past. They were the result of incredible advances in engineering and innovation as new, powerful civilizations emerged and came to dominate the ancient world. Many of such ancient inventions were forgotten, lost to the pages of history, only to be re-invented millennia later. Among the best examples of ancient technology and inventions are: 2000-years-old metal coatings superior to today’s standard; 2000-years-old Bagdad battery; 1600-year-old Roman artisans of impregnated glass with particles of silver and gold; the Assyrian Nimrud lend of the oldest telescope; the steam engine by the Hero of Alexandria and many more (https://www.ancient-origins.net/ancient-technology/ten-amazing-inventions-ancient-times-001539).

Prosperity – Africa in the 21st Century

In a series of posts we will explore why the 21st century will be prosperous for Africa. Indeed, there are various reasons to predict why Africa will continue to shine more and more though the threats that climate change, including global warming, will hit Africa more than other continents (https://en.m.wikipedia.org/wiki/Climate_change_in_Africa). Naturally there are other threats that so far hindered Africa from faster developments as compared to the rest of the world, specially that the history of Africa is very much different. Here is a list of key factors, among others, about the ongoing tectonic changes and drivers that will bring a lot of positive socio-economic impacts in Africa.

– African identity, slavery and colonialism distorted her identity and disoriented her values. However, Africa was not the only continent that suffered colonization. The concept of African identity has changed are still changing relatively fast specially with the growing restrictions in migration.

– African independence, decolonization and transition to independence characterized the past century and national identities in many parts of Africa are gradually emerging.

– Large-scale infra-structures, there are mega projects taking place in Africa (the case of Egypt participation in partnership for goals, Goal 17 of UN-SDGs) such as developing its transport systems to connect the continent from the very north in e.g. Egypt to its very south, South Africa, also from the west to the east (https://www.egypttoday.com/Article/1/77914/Egypt-launches-32-projects-in-Africa-in-1-year-report). One example is the enormous use of smart phones technology in trade, business and finance.

– Coupling rural to urban regions, this among key and important issues in the development of Africa as 70% of African are living in rural Africa and producing 70-80% of agricultural outputs.,

– African Union, AU is a continental body of the 55 member states that make up the African Continent. It was officially launched in 2002 as a successor to the Organisation of African Unity (OAU, 1963-1999).

– Human resources, population growth and youth, towards 2100 the population of Africa will peak to about 40% of the world population with very high percentage of youth.

– Natural resources Africa is abundant with natural resources including diamonds. gold, oil, natural gas, uranium, copper, platinum, cobalt, iron, bauxite and cocoa beans. This is of course in addition to its amazing biodiversity.

– Generation shift, new generations and leaders are currently shaping and reshaping Africa, combating corruption, enhance good governance and transparency and taking advantage of modern technologies, e.g. ICT, IOT, crowdfunding, protection of natural resources, also in the energy, agriculture, farming, tourism and other sectors.

– Security, many African countries are becoming more aware about the improvement of national integrity and internal security and safety of population specially that Africa has a complex diversity of ethnic groups. Remarkable developments in safety in Africa took place and still the focus of the African countries.

– Biggest market in the world, the needs of Africa will make it one of the biggest market in the 21st century. There is diversification and expansion the economy and trade both internally and with the rest of the world including Europe and Asia. This will generate tectonic changes in international trade, business, transport and mobility in labor and services.

– Global investments. Based on data through 2017, France is the largest investor in Africa, although its stock of investment has remained largely unchanged since 2013, followed by the Netherlands, the United States, the United Kingdom and China. Geographically Europe and Asia can be linked through North Africa and the GCC countries.

– UN-SDGs the world has created a global agenda for promoting and implementing sustainability which Africa will benefit considerably from it. UN-SDGs and involved targets for developments are key issues that are shaping policies and strategies to cope with poverty, hunger, gender, inequalities, education quality, health, water and sanitation, energy, strong institutions, life quality, biodiversity, ……. etc.

THE DESIRE TO TEACH their children about computers drew these Samburu women to a classroom in a settlement north of Nairobi. They are learning about tablets—designed to withstand tough use—that connect to the Internet through a satellite and come preloaded with educational programs. Technology now has arrived in isolated regions of Africa primarily in the form of relatively inexpensive cell phones.
