Category: Water Resources

The global inventory of fresh surface water resources is about 0.3% of the total water available on the earth. The major part of these resources (87%) exists in lakes and only 2% flows in rivers while the remaining (11%) is trapped in swamps. The remainder of the global freshwater resources, which amounts to double the surface water resources (i.e. 0.6%), exists in icecaps and glaciers (67%), and groundwater (30%). The global inventory of fresh surface water is conservative, i.e. constant, as the earth is a closed system in this respect. However, the quality of fresh surface water on the earth’s surface has gone through, and still, gradual degradation by the increasing waste and pollution as a results of growing population, consumption of natural resources and industrialization as well as severe lack of regulations for protection of global water resources. Also, groundwater resources are facing tremendous threats both in terms of quantity and quality. Freshwater resources management is essential for achieving sustainable socio-economic developments through implementation of best water practices in all society sectors. Existing and emerging competition on freshwater resources on national, regional and global levels, and the diverse interests among stakeholders in public and private sectors, call for Water Framework Directive to achieve good qualitative and quantitative status of all water bodies including trans-boundary waters and marine water up to one nautical mile from shore. There are constant needs for developing treaties, conventions, regulations and agreements on all levels, sectors and consumers. This involves taking in consideration the nature of local, regional and global cycles and their interactions with climate, environment, humans and the techno-sphere. Management of water resources has to consider the complex interactions of water sectors, stakeholders and consumers with all other society sectors, in particular energy, agriculture, industry and household sectors. Among important issues for achieving sustainable socio-economic developments world over is affordability and accessibility of safe water resources for all society needs.

🛑 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.

Would Liquid Metal Batteries Revolutionize Energy Storage?

Energy is one of the three main drivers, i.e. water, energy and natural resources, of all life forms on Earth. The sustainability of these three main drivers is a pre-request for our survival and more importantly for the survival of all forms of life on Earth (https://youtu.be/f6kwNNdOVr4), and more importantly for prosperity and improved life-quality. Unlike the other two drivers, energy conservation is of much more importance not only to satisfy our daily needs but on the first hand to cope with the many direct and indirect existential threats facing life. Also, how much energy we are consuming determines how much natural resources, including water, we would need for our activities. Energy in all its forms, either as stationary fossil or dynamic renewable resources, has complex interwoven challenges as it is strongly coupled to the social, environment and economic pillars of our modern lifestyle. Also, all energy production, distribution and uses are more or less, associated with different degrees and levels of negative impacts. Progress in energy conservation and renewable energy sources is determinant for the ongoing sustainability revolution not only to a climate-compatible circular economy, but also essential for achieving sustainable and resilient societies (UN-SDGs). We therefore need to be less dependent on fossil-fuel based-energy and to scale-up and scale-out clean and sustainable energy resources on the global scale. Renewables without appropriate affordable storage is not sustainable, we need also to have different sustainable and resilient storage alternatives for solar and wind energy solutions that can meet the different environment, weather and climate conditions. For example, limitations do exist in hot regions as in the MENA region and other parts in the world where the Li-ion batteries may not be the best choice. Also, manufacturing and production facilities need to be available where the natural raw materials for production are abundant. So, what regards batteries, one-size-fits-all option is unlikely to be sustainable and resilient under all conditions.

Moving away from fossil-fuel (coal, oil and gas) to renewable energy resources isn’t an overnight process as it is associated with many complex challenges specially what regards the huge needs of electricity generation, use and consumption, i.e. production and supply (https://youtu.be/eRz46AwPcSc). Solar and wind are becoming increasingly crucial for scaling- up and scaling-out the renewable energy resources. However, the very nature of these renewables by being intermittent sources and the fact that there is a wide-range of dynamic and variable needs by the stakeholders around the world in terms of intensity of energy needed in different applications.

One important aspect in the scaling-up and scaling-out the use of the renewable energy resources of solar and wind energy is battery-storage. Li-ion batteries, though are currently one of the best storage facilities, they still have several limitations to fulfill full scale applications that are required by the markets’ needs. Lithium-ion batteries are not necessarily the only ‘one-size-fits-all’ solution for the energy storage of renewable solar and wind energies. They prone to fire and require extensive non-renewable resource extraction from the earth which may not be sustainable in the longer run because of the side-effects associated with their production and processing as well as the complete LC ‘life-cycle’ of the batteries, i.e. effective recovery of the raw materials.

An alternative new technology for energy storage is emerging in the world market. The US-based Ambri is now one of the so-far leading alternatives in energy storage and it aims to lower electricity costs, enable easy access and widespread usage of renewable energy systems, among other things. It is doing this by working on alternatives to lithium-ion technology such as liquid metal batteries and antimony electrode-based cells that are more resilient, long-lasting and eco-friendly (https://youtu.be/NiRrvxjrJ1U; https://www.google.se/amp/s/www.moneycontrol.com/news/business/ril-rnsel-mukesh-ambani-ambri-renewable-energy-storage-7314091.html/amp). This liquid metal battery is an innovation in stationary electricity storage invented by Prof. Donald Sadoway, MIT, USA. At present Ambri can cater to projects that require energy storage systems from 10 MWh to 2 GWh. Energy-intensive industries need to reach climate neutrality by 2050. Various technologies are available for the decarbonisation of the iron and steel, chemicals, refining and cement industries as well as the existing financial instruments (https://www.europarl.europa.eu/RegData/etudes/STUD/2020/652717/IPOL_STU(2020)652717_EN.pdf). However, suitable energy storage technologies are still needed to help shape and enhance the transition to a climate neutral industries, specially the energy-intensive ones, not only in Europe but around the world.

Energy storage is vital not just for the business of mobility but for reducing the overall cost of electricity and, more importantly, mitigating climate change. It plays an integral role in the development and integration of renewable energy technologies—a technological space that is seeing rapid development. Energy storage is an indispensable bridge between intermittent renewable power and a constant, glitch-free supply of electric energy. Achieving sustainable and resilient societies would require having diverse and customized solutions to meet an increasing need of off-grid and decentralized energy-options, e.g. in rural and remote areas for household (https://youtu.be/yxABosWfuus) and also for energy-intensive industries (https://youtu.be/m8751tkBU_Q; https://youtu.be/m8751tkBU_Q; https://www.energy-storage.news/ambris-liquid-metal-battery-to-be-used-at-desert-data-centre-in-nevada/). As this will unload overpopulated urban areas and cities. The needs of such options are timely because of the huge flexibility that is offered by ICT ‘Information Communication Technology’ and AI ‘Artificial Intelligence’ that allow not being totally dependent on urban areas and cities. Agriculture and rural areas are still essential for our living and they are the underlying platform for supporting urban areas and cities.

It is still interesting to see how this new approach of liquid metal batteries for storage of renewable energies from solar and wind will continue their long-term progress (https://www.google.se/amp/s/www.forbes.com/sites/davidblackmon/2021/09/02/bill-gates-backed-startup-might-change-the-renewable-energy-storage-game/amp/).

Ambri a new addition to battery technology.

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.

COVID-19: Crisis and Challenges in Higher Education. The New Imperatives and Opportunities.

COVID-19 has changed the reality of life for many of us and will continue to do so for sometime. The first sectors that suffered from the COVID-19 pandemic were health services, the tourism and hospitality sectors along with other labor, trade and industry sectors.

Higher education, and education in general, has also been impacted by COVID-19 in various ways and are facing a global crisis that may take relatively longer time to recover depending of level of preparedness, availability of resources, existing infrastructures and degree of resilience. However, the crisis in education and higher education didn’t come as a surprise as it has been an ever growing cracking in higher education and global education systems in general, since the birth of ICT and IOT, and even before that. Indeed, many education systems around the world are either inherited or imported which have caused ever increasing gaps between what students get from their education and what is really needed in the market specially in the developing countries. Another short coming in higher education is the strong rooted tradition in out-dated disciplinary-based education systems where graduates have serious difficulties to meet today’s complexity in the labor market. The ongoing crisis is of global dimension and has introduced remarkable effects in R&D and also the associated educational infra-structures.

COVID-19 has changed our world dramatically and as we have in business and trade if you’re a brick-and-mortar retailer, an online store is no longer a nice-to-have; it’s essentially a must-have (https://www.bigcommerce.com/articles/offline-to-online/brick-and-mortar-retailers/). It is an inductive process that will be propagated very fast in all other sectors with far many new imperatives. All people simply need to be able to find you and communicate with you online. The COVID-19 has put new imperatives on sharp display when many brick-and-mortar stores were forced to temporarily shut their doors. Having an online store was the only way forward and it is likely that our world will change, at least partially in this direction as was the case with the old postage-system, to online banking, on-line booking of hotels, food, travels and all other ICT-services. Indeed, education will follow the same trend in a way or another. Though, the brick and mortar framework will still be the mainstay of our education system, for sometime, because of its undeniable advantages to learning in a shared physical space, online education is progressively and continuously gaining popularity. Still there are obstacles that need to be solved and will be solved. It is not a matter any longer of IF but rather WHEN and when was already yesterday. The autonomy and flexibility of e-learning make them extremely popular with working professionals and students as the entire e-learning industry is changing rapidly. This is an essential part of the ongoing Information Revolution.

Though there can be challenges to successfully tune and transform higher education systems, and the whole education landscape in general, from Brick & Mortar to Click & Mortar (https://digitallearning.eletsonline.com/2019/12/education-landscape-from-brick-mortar-to-click-mortar/) there are major long-term benefits and opportunities for generations to come. However, as we have learned from history higher education, and education systems, by being part of our social landscape are very much dependent on our lifestyle. Our life as we have it today and as it would be in the future is very much impacted by moving away from Brick & Mortar to Click and Mortar as the digital technologies are definitely here to stay and we have to adapt to this imperative reality. Sustain-earth.com will expand on many issues related to future threats, challenges and opportunities what regards higher education and and education in general.

Sustainable Developments and Role of Water-Energy Systems in the Anthropocene

Our water-energy systems around the world have complex and comprehensive interactions within and between each other. Yet, the complexity is accelerating more and more as global water-energy resources are also dependent on in the ongoing changes in the climate and environment. More importantly, the growth in world population along the increasing needs for water, energy, food and natural resources as well as eco-system services add new dimensions to how and when we can achieve the goals of the UN-SDGs.

The WEBINAR https://youtu.be/G3D0X96IuqY conducted at Boston University throws some light on what, why and how we can advance our knowledge on water-energy-food-climate nexus.

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.

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.

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.

Hear the message from Prof. Ezzine in two videos (in French https://youtu.be/SfOQu90yzqs; and in English https://youtu.be/oCdz9Je6yvA).

HR-Group for UN-SDGs in Africa – Prof. Amidu O. Mustapha.

Sustain-Earth.Com will work on mobilizing Human Resources in Africa for empowering the youth and students for scaling up Science, Technology and Innovation ‘STI’ to promote the UN-SDGs. We are delighted to have Professor Amidu Olalekan Mustapha from University of Agriculture, Abeokuta, Nigeria to work on these issues.

Furthermore, the necessary instruments and tools will be developed and implemented for active engagement of the higher education, universities and research institutions in Africa to couple ‘STI’ to society, population and market needs. University graduates, early-stage researchers and professionals (according to scientific and technical merits) through dedicated mentoring programmes will act as catalysts in creating the necessary multi-layered links with relevant stakeholders in all sectors and on all levels. The diverse, rich and wide-range of higher education and research programmes in Africa will provide the necessary Human Resources ‘HR’. This will involve raising the public awareness among the involved stakeholders. A data-base will be created to define, collect and compile the expertise, professional and the targeted stakeholders.

The involvement of high-level interactions with sectors and organisations as was the case in previous trans-disciplinary and trans-sectorial activities, e.g. IRPA-Nairobi Conference in 2010 (http://www.iur-uir.org/en/archives/conferences/id-44-afrirpa2010-third-african-irpa-regional-congress) will be assessed. This will be part of building on previous experiences and successes of already existing networking infra-structures. However, this will still require major challenges but suitable grounds will be found for what and how to do. According to Professor Amidu Mustapha there are a number of existing initiatives and platforms that we can link up with, e.g. both in Nigeria and Kenya. The members of the existing groups may also have other goals in addition, but we can benefit mutually in the common areas of environmental sustainability and knowledge development especially among youths.

A starting point will also involve reshaping and tuning two previously given courses at Uppsala university in 2018 and 2019 (http://teknat.uu.se/digitalAssets/395/c_395062-l_3-k_sustainability-in-science-and-technology.pdf; http://www.teknat.uu.se/digitalAssets/395/c_395062-l_1-k_sustainability-in-science-and-technology-2019.pdf). In these two course water, energy and natural resources nexus were detailed in order to explore what, why and how these drivers can be coupled to socio-economic-environment aspects that are necessary to help the ongoing transformation to sustainable societies. Over twenty professors and professionals were involved in conducting these courses, however there are still enormous needs to develop and extend these courses to meet the realities in many developing countries specially in Africa. This is also while considering the practical approaches that would be required in the implementation process. Particularly what regards the existing and emerging needs (UN-SDGs) in Africa for practical and appropriate policies and strategies.

ESG Sustainability Factors – Godfrey Mchunguzi Oyema

Sustain-Earth.Com is introducing an ESG (https://en.m.wikipedia.org/wiki/Environmental,_social_and_corporate_governance) Fund-Raising team where Mr. Godfrey Mchunguzi Oyema, Tanzania, is excellent addition to sustain-earth.com. Mr. Godfrey Mchunguzi Oyema is a passionate and results-driven Environmentalist, Biodiversity (Wildlife) and Human Ecologist, ESG policy professional with understanding of the challenges facing biodiversity both in-situ and ex-situ conservation. His work involves analytical approaches to using observation strategies to predict and monitor behavior changes of animals in captivity and natural habitats. He has diverse and rich knowledge of managing animals in captivity using a variety of methods, as well as camera traps and behavior monitoring. His expertise is based on smooth business operations by collaborating with project partners and following projects from conceptualizing phase to completion including theory of change design, incorporation of partner needs and technical support.

Environmental, Social and Governance (ESG) are three central factors in measuring sustainability dimensions and the societal impact of investments in companies. The social and environmental responsibility affects financial and economic performance in private and public sectors. The social capital is an important factor in establishing strong human capital and so is the case of the underlying environmental conditions of social frameworks. These are important in encouraging companies and capital markets to incorporate environmental and social challenges into their day-to-day decision-making.

ESG had also received most of the public and media attention, not least because of the growing fears concerning climate change which directed the spotlight more and more onto the corporate governance aspect of responsible investment. It brought also the focus to how the companies were managed, what the stockholder relationships were and how the employees were treated. The evidence toward a relationship between ESG issues and financial performance is becoming greater with wider recognition of the necessity of the sustainability in long-term investments. The environmental social and corporate governance are becoming increasingly important in the investment markets https://www.investopedia.com/terms/e/environmental-social-and-governance-esg-criteria.asp).

Public goods are natural resource enjoyed by every person and it is impossible to prevent someone, including living organisms, consuming such good, e.g. air for breathing, water for drinking, sun and light to enjoy. Public goods are recognized as beneficial for everyone and therefore have existential values and necessities that must not be destroyed by one person or state. In this context, natural resources and the environment are global public goods that are should not be diminished, exhausted and/or degraded, e.g. a breathable atmosphere, stable climate and biodiversity. For these reasons Environmental Governance (https://en.m.wikipedia.org/wiki/Environmental_governance) is also a political ecology and environmental policy concepts that advocates sustainability for management of all human activities. Governance includes government, business and civil society.

Sustain-Earth.Com will expand on ESG and its growing importance for promoting and achieving the UN-SDGs (https://www.un.org/development/desa/disabilities/envision2030.html).

Africa’s Future Gold Mine – Renewable Energy Future Opportunities and Needs

Africa has enormous untapped resources of renewable energy resources such as solar, wind, geothermal, bio-energy and hydro-power (https://www.renewablesinafrica.com).

Africa has the highest incidence of food insecurity and poverty and the highest rates of population growth. Yet Africa also has the most arable land, the lowest crop yields, and by far the most plentiful land resources relative to energy demand. It is thus of interest to examine the potential of expanded modern production of renewable in Africa. Renewables in Africa are future strong enablers and drivers for sustainable developments with enormous socio-economic-environment benefits. Renewables in Africa will help to achieve its vision for Green Growth (https://www.greengrowthknowledge.org/sites/default/files/downloads/resource/African%20Development%20Report%202012_4.pdf). In Brazil, for example, bioenergy development have been synergistic rather than antagonistic. Realizing similar success in African countries will require clear vision, good governance, and adaptation of technologies, knowledge, and business models to myriad local circumstances. Strategies for integrated production of food crops, livestock, and renewables, e.g. bioenergy are potentially attractive and offer an alternative to an agricultural model featuring specialized land use (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4337098/). If done thoughtfully, there is considerable evidence that food security and economic development in Africa can be addressed more effectively with modern bioenergy than without it. However, what regards bioenergy which is so far a major resource of energy in Africa, researchers warn about its negative climate impacts and a brake on bioenergy by 2050 is suggested. This will alleviate the extreme pressures on land in the coming 30 years and avoid the negative impacts from high carbon footprint and excessive land use biomass production from crops, trees or grasses for fuel through 2100 (https://www.google.se/amp/s/phys.org/news/2019-12-bioenergy-negative-climate-impacts.amp).

Here we illustrate an excellent example of renewables from one of the African pioneers in Geothermal power generation in East Africa and the Rift Valley (https://geology.com/articles/east-africa-rift.shtml). The geology, evolution and landscape of the Rift Valley (https://geology.com/articles/east-africa-rift.shtml) in Africa makes it a unique resource and an example of the untapped renewable energy resources. Working opportunities in the energy market in Africa would open huge employment possibilities for technical engineers, including ICT.

DM and CEO of KenGen Rebecca Miano, Kenya, gives us a glimpse on the future of Renewables in Africa (https://m.youtube.com/watch?v=XOreOpeqQ4o&feature=youtu.be). KenGen as a global pioneer in geothermal energy in Africa and the world, it has access also to affordable inhouse expertise to meet crises such as COVID-19. However, demand in energy for expansion and modernization of power plants are enormous and would need more and more technical skills.
