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 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.

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.

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.

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.

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.

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.

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.

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).

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.

Though many journeys and expeditions were done to discover the secrets of the Nile, very few of them, if any at all, touched upon the diversity of life, traditions and cultures of the Nile people. The Nile people have deep rooted love and worship for the Nile and its waters for thousand of years. The Nile and its waters meant, still mean and will continue to do so for generations. The life of the Nile people is as complex as evolution and history of the Nile itself. In this context, the socio-economic performance of the people of the Nile is very central and crucial for finding sustainable and peaceful ways to share such magnificent gift of nature. These indeed, are parts of wicked conflicts of how to put such enormous diversity in political agreements for lasting harmony in the Nile Basin as a whole. This is also the case of the rest of Africa as rivers and their catchments are basic landscape units of existential importance for the livelihood of the African population. However, vast regions of Africa don’t enjoy surface water resource or rain and other alternatives are imperative such as groundwater, desalination and water reuse. In most cases we need to think in 3D-solutions that couple surface water with groundwater and also to understand the long-term consequences of water production, use and consumption on the landscape level on longterm and large-scale levels. This can be simple to say if such resources were infinite, however water scarcity in Africa is the highest in the world yet major threats are emerging due to climate change, growing population, increasing diversification in economy, acceleration of urbanisation and industrial activities with all consequences of growing waste and pollution. The search for how such transboundary solutions of the water resources to be shared is a major political issue. All of this come in the time of today’s very rapid and fast growing ’diversification’ of the socio-economic-environment conditions needed for the ongoing transformation to sustainable societies.

Joanna Lumley’s journey, in search for the very source of the Nile, by being the longest river in the world, comes with very interesting introduction on the cultural diversity of the life and livelihood of the population in the Nile Basin. Among the amazing issues is the longstanding socio-economic diversity that shaped the life in the Nile Basin for thousands of years ranging from e.g. evolution of tourism; preparation for marriage; social gathering and social therapy ‘Soffi’; beauty treatment ‘Dukhan دخان’ (form of SPA) of body, skin and smell; sports in rural areas; local food and drinks; coutry-side work and services. Traveling, for example, comes with major challenges because of the unique landscape in the African canyons, river-catchment and forests. Respect and appreciation of cultures is the secret of not only social success but more importantly to bring about harmony and resilience in the complex social mosaic that requires modern understanding of ‘what, how and why’ issues in modern sustainability.

Just to give few examples is how to live and travel in one of Africa’s largest canyons of the Blue Nile, 250 miles long. Also, how to manage the 60 rivers that drain rainwater to Lake Tana in Ethiopia. The country with 4/5 of the african mountains and Africa’s oldest cultures that is most diverse with great influences from ancient Egypt and Arabia.

One of the great future challenge of the 21st century is how to deal with the growing scarcity of Africa’s white gold ‘water’ (https://en.m.wikipedia.org/wiki/Water_scarcity_in_Africa As of 2006). One third of all African nations suffers from clean water scarcity and Sub-Saharan Africa has the largest number of water-stressed countries of any other place on the planet. It is estimated that by 2030 that 75 million to 250 million people in Africa will be living in areas of high water stress, which will likely displace anywhere between 24 million and 700 million people as conditions become increasingly unlivable.
