Our well-being on planet Earth depends on three main essential drivers, i.e. Water, Energy and Natural Resources (fossil minerals and renewables including biosphere and its eco-systems) ‘WENR’. To achieve sustainability and resilience in our societies and to promote prosperity requires using and sharing our common 'WENR' capital with consideration to the complex and multi-layered NEXUS, i.e. the interactions and processes within and between these three drivers 'WENR’. Currently, Earth is facing existential threats caused by us collectively. Scaling-Up and Scaling-Out 'Science, Technology and Innovation' of the WENR-systems and coupling them to the 'Socio-Economic-Environment' pillars of our societies as defined by the UN-SDGs are one of the very few means to mitigate existing and future threats and bring full vitality in the functioning and metabolism of all life forms and processes on Earth.

Capital (economics) is used in production of good and services. In this context a growing number of accounting systems have recognized the concept of taking into account natural and social capitals “Triple Bottom Line”, i.e. including ecosystems and social relations in the definition of capital. Control of capital is a primary mean for creating and maintaining wealth though it may depreciate in the production process (physical or manufactured capital) and consumption (natural or non-manufactured capital). Capital is an input for in the production process, and thereby homes and personal autos are regarded as durable goods rather than capital. In economic systems, investment is the accumulation of newly produced physical entities, e.g. factories, machinery, houses and goods inventories. In finance, however, investment is using money with the expectation of capital appreciation and interest earnings.
For achieving sustainable socio-economic developments the “Triple Bottom Line” is expected to create and maintain long-term and large-scale economic and financial stabilities with consideration to successful conservation of the global natural resources.
The world is currently facing growing pressures for transformation to clean energy in order to mitigate the environmental and climatic impacts of traditional energy sources. For Canada transformation to clean energy is still a big challenge, however it represents a unique opportunity for traditional energy producers and clean energy producers to team-up. These players have to come-up with a coherent task with the government to assure further development of traditional sources of energy in environmentally responsible manner while at the same time start grow more quickly to clean electricity sector. Resolving these issues will make it possible to meet the challenges for the transition to clean energy.
Similar challenges for countries with high carbon dioxide emission per capita, also, exist around the world but not all the countries have the same possibilities and resources for full and quick transformation to clean energy because of necessary huge capital investments, access to the required high-tech infra-structure/expertise and above all the political will. However, countries with low carbon dioxide emissions per capita, e.g. in Africa and South America, have to implement policies and encourage promotion of clean energy production while building up their technology, industry and production sectors.
While there are no “standard maps” for achieving successful sustainable socio-economic developments everywhere in the world, yet we can learn from exiting strategies and solutions. Naturally, nations around the world have own conditions, structures, needs and may exist in different stages of development with complex internal and external political, economical and trade relations. Assessing the existing models and strategies helps formulating short and long-term roadmaps that are appropriate and suitable to the socio-economic needs and conditions. Successful socio-economic developments can’t be based on random actions and have to follow robust strategies emanating from effective, collective and coherent interactions between all sectors and on all levels. In this context, cloudy and conflicting interesting “within and between” nations can be major obstacles for achieving sustainable socio-economic developments.
An example on how to build national roadmaps for bring about successful socio-economic developments even under economic constrains is given here.
UNEP along FAO, ICRAF and a number of Sudanese NGOs and institutes describe how and why the agricultural sectors in Sudan were gradually degraded and moved rapidly towards more or less total collapse because of environment over-taxation. Since the introduction of mechanization of rain-fed agriculture by the British in 1944 several negative impacts, due to lack of control and planning, were piled up during the last half of the 20th century. This has caused large-scale destruction of environment and triggered severe negative impacts in other sectors as well. The traditional and mechanized agriculture account for 55 and 45 percent respectively of the rain-fed cultivated area. The importance of the irrigated sub-sector is reflected in the fact that while it makes up only 7 percent of the cultivated area, it accounts for more than half of the crop yields. However, irrigated land has own problems. Rapid, uncontrolled privatization, random investment and failure to couple education and research to market and society needs are major causes.
Management of land-water resources in Africa is IMPERATIVE. However, past experiences show not only major failure but the great threats of the blind and random implementation of imported technologies, e.g. Sudan where its cultivable land is about 42 percent with frequent claims that it is the potential ‘breadbasket’ of Africa and Middle East. Agriculture, the largest economic sector in Sudan, became the heart of some of the country’s most serious environmental problems: wide-range of land degradation, riverbank erosion, invasive species, pesticide mismanagement, water pollution and canal sedimentation. Also rangeland’s vulnerability to overgrazing is high and its overlap with cultivation is a major source of potential conflict. The significance of these threats cannot be underestimated: not only are 15 percent of the population partly or wholly dependent on imported food aid, but the population is growing, per hectare crop yields are declining and the enhanced competition over scarce agricultural resources.
The agricultural sector in Sudan is the main source of sustained growth and backbone of Sudan’s economy. Unfortunately, the sector’s economic stake is declining more and more with the emergence of the oil industry. Sudan continues to depend heavily on agriculture, whose share fluctuates around 40 percent of the GDP. The crop and livestock sub-sectors together contribute 80 to 90 percent of non-oil export earnings. With these trends the country will face more unemployment and famine as fifty-eight percent of the active workforce is employed in agriculture and 83 percent of the population depends on farming for its livelihood.
Global warming adds new threats as the agricultural sector in Sudan is highly vulnerable to shortages in rainfall and there has been substantial decline in precipitation and climate change models predict that this trend will continue. Without major action to stop the wave of de-gradation and restore land productivity, the natural resource base will continue to shrink, even as demand grows. Resolving this issue is thus central to achieving lasting peace and food security.
Eric Maundu, owner and founder of “Kijani Grows” (“Kijani” is Swahili for green), isn’t a farmer, he’s an engineer with a computer science degree from USA. Maundu himself ran from agriculture in his native Kenya- where he saw it as a struggle for land, water and resources. In the USA he felt the negative impacts of urbanization, industrial waste and traffic pollution on contamination of soils and degradation in land-water resources. In industrial/urban areas and cities, freeways, roads, light rail and parking lots so there’s not much arable land and the soil is contaminated. With these threats in mind he realized he could farm without soil, with little water via aquaponics and with possibilities to use “self-cleaning” and recycling as well as that he could apply his robotics background to farming. An amazing combination of: physics; chemistry; biology; ecology; and computer science in one system.
No soil, instead Maundu is growing plants using fish and circulating water. It’s called aquaponics- a gardening system that combines hydroponics (water-based planting) and aquaculture (fish farming). It’s been hailed as the future of farming: it uses less water (up to 90% less than traditional gardening), doesn’t attract soil-based bugs and produces two types of produce (both plants and fish)., i.e. a full meal!
Maundu- by being trained in industrial robotics- has taken the agricultural craft one step further and made his “aquaponics” smart. Using sensors (to detect water level, pH and temperature), microprocessors, relay cards, clouds and social media networks. Maundu has programmed his gardens to tweet when there’s a problem, e.g. not enough water or when there’s news, e.g. an over-abundance of food to share. With these smart solutions the same information can be shared with farmers in Iceland and China.” Maundu believes that by putting gardens online, especially in places where solar-powered gardens are totally off the grid), is the only way to make sure that farming remains viable to the next generation of urban youth.
There are many technical approaches and levels of complexity for turning leftover food and manure till biogas. Understanding the underlying science and concepts in a simple way can help to gradually construct and develop own solutions to achieve affordable, efficient and friendly fuctional facilities.
You have input material, i.e. initial reactants that are processed under reduced “anaerobic” conditions, i.e. air free from oxygen through using sealed containers, at a suitable temperature, and more or less neutral conditions. The temperature range can vary around 40 degrees celsius, and to be controlled using heat from the sun along with suitable insolation if necessary, i.e. depending on region and season. The initial reactants have to be crushed to facilitate the bacterial reaction where we have two types of bacteria, e.g. those creating acidity and those producing methane. There are high-energy organic matter, i.e. those with high sugar and high carbohydrate content, and low-energy organic matter such as grass and manure (more or less consumed organic matter). High-energy food promote production of acidity, i.e. “acid” type of bacteria while the other methane-producing bacteria are much more accessible in animal manure. The liquid leftover “effluent” from the whole process may be used fertilizer, however it can be beneficial to do some analysis to see the quality in relation to the composition of the reactants. In this context, adjustment of the control parameters, i.e. temperature, duration and acidity as well as the composition of reactants can be part of development and optimization of the production facilities.
The needs, drivers and tools to make life accessible, affordable and sustainable on earth are explained and described at “Sustain-Earth”. Take a cop of coffee or tea and explore what “Sustain-Earth” is ABOUT.
Our understanding of algae, their unique and rich diversity, is shifting more and more towards finding industrial applications for production of useful products, in particular, food (human food, fish food and animal food), energy and farmaceutical products. There are known methods and tools to extract oil and other valuable products from algae, also to change the genetic content and chemical composition of many algae.
Many and many organizations give lots of money for research for commercialization of algae. Research takes is typical path fuelled by society needs, human hopes for prosperity and fears from environmental threats. In this amazing journey of what we are right now and where we are heading to, there are several important facts to be known, e.g. benefits and threats. There are, also, key interests in understanding the potential of artificial photosynthesis as a new path, not yet fully understood, for production of energy.
Algae are “biochemical reactors” that can recycle carbon to produce organic compounds in different forms, which indeed is the origin of all the gas and oil reservoirs around the world. Multi-hundred-million dollar industries have invested in many products, e.g. sushi wrap, oils, dental impression, ice cream thickener, cosmetics, medical products, plastics… etc. They still invest more and more money for production of energy-rich food, biofuel from algae and use of wastewater to grow algae as well as for the extraction of other useful products like coloring agents and anti-oxidant, agro-culture business for production of food in the fish and shellfish industries.
Basic research is needed, and even imperative, to solve central bottleneck in algae processing technology ranging from cultivation, harvesting, extraction of desired products, processing and refining. Micro-algae are known to grow very fast and there is commercial potential in industrial microbiology where molecular biology in combination with aquaculture and marine farming can yield hybrid and novel technologies. Unlike industrial small-scale microbial technologies, e.g. cheese, beer, alcohol that are based on “closed systems” trying to cultivate algae on large-scale, i.e. in open systems, is a great challenge. Algae are now looked upon as the most sustainable known potential source of biofuel. The challenges are transferring the many different types of small-scale bioreactors to open systems for growing algae at large scale. Up-scaling of algae-based technology leads to emergent issues that are not fully controlled, e.g. competitor algae, predators and diseases (bacteria and viruses). Up-scaling to large-scale open systems, therefore, requires solving a wide-range of difficulties and threats including those arising from varying weather conditions, e.g temperature, and much work is still needed.
Earth – the blue planet: lots of water-lots of algae-lots of oxygen. The most important and oldest single cell plants on earth “The Algae” and the very reason of our existence. These single cells carry lots of secrets and many of them are still unknown to us though they played important roles in the evolution and development of life on earth. They have micro- and nano- devices with complex molecular structures and diversity of biochemical metabolic reactions, e.g. photosynthesis and nitrogen fixation, production of amino acids and lipids. Algae with thousands and thousands of species can be very small or very large in size with different colors and can be useful or harmful. Algae remains, diatoms, can be preserved in sediments for millions of years. The most important is that algae are the origin of gas and oil and recently that algae can be used for production and a source of biofuel!
Agricultural production is very much dependent on land-water resources and in recent decades there have been trends towards new agricultural solutions either to substitute the increasing degradation in land-water qualities or to find new agricultural alternatives more suitable for arid and semi-arid climate.
Degradation in water quality resulting from waste, pollutions and sanitation on the one hand, and reduced land quality due to decreasing soil fertility, man-made technological interferences “dams”, soil erosion and climate change on the other, triggered new shifts in agricultural technologies. Traditional agricultural techniques are becoming more and more dependent on artificial fertilization either to compensate for decreasing soil fertility and/or to increase soil productivity.
Chemical pesticides are still in use, inefficient irrigation routines and further pressures on water resources have, also, caused gradual degradation in land-water resources in particular the large-scale and long-term negative impacts on water resources.
These trends have forced shifts towards new agricultural technologies that either rely on less land and indoor green-house solutions and/or what is known as “complete liquid fertilizers” as well as clean sterilized organic-fertilization. These solutions, foliar spray, fertigation programs, hydroponic solutions, aireal/soil application of “liquid complete” and/or “sterilized clean organic” ferilizers” have new advantages. However they either shifted focus to alternative solutions that may require additional costs, i.e. making food production less economic, or made farming and agriculture that can not afford the new technologies to continue their “business-as-usual” traditions.
220 AD The Great Wall, 1420 AD The Forbidden City, 1997 AD Three Gorges Dam and 2002 AD China does again with the biggest construction project on earth in the middle of the deep ocean. That is to meet the 21st century where China’s export-import trade is exploding by nearly 30% each year and to support the heavy traffic from Yangtze River where there is considerable sedimentation of silt where it meets the ocean.
This China’s Ultimate Mega Port, The Yangshan Port, is one of the busiest cargo facilities on earth with the world biggest import-export trade. It has one of the most advanced and cutting edge control system in any container port around the world. It is 32 km off-shore and 15-20 meters deep, a 20 km cargo-port that can handle 25 million shipping containers in one year, i.e. 70 000 in just one day and to built it required thousand of million cubic meters of soil. It is built for loading and unloading gigantic containerships and linked to the main land China by the second world largest bridge.
There many examples of businesses in the public sector that went over to private owners, and visa-versa, with major political transformations/reforms. Such major shifts from private-to-public or public-to-private were not always performed on sustainable long-term policies with solid assessment analysis of the socio-economic consequences. Sustainable economic management requires taking in considerations how the lifecycle of companies may look like in a turbulent and dynamic world.
The world is experiencing tectonic changes in terms of population, economy, production, services and technology. The world in the year 2050 will not any longer be as it used to be in the past decades.
The world population will grow from 6 billions in the year 2000 (one billion in the developed world and five billions in the developing world) to 9 billions in the 2050. One hundred million out of the three billions of the global increase in population will go to the developed world, while the developing countries will increase by 2.9 billions. This is a dramatic shift in world population in the coming five decades only, i.e. an increase from 6 to 9 billions.
The other consequential change is, by the year 2000, the developed world (one billion people) had 80% of the global economy while the developing world (five billion) had the remaining 20%. But, by the year 2050, the developed world will have only 35% of the world economy, while the developing countries will have 65% of the global economy. So, the 80% vs 20% of global economy of the year 2000 will be change to 35% vs 65% by the year 2050. This is just turning the world on its head in terms of the world that used to be in the past decades. This dramatic change in the structure of world economy is being driven by the development in global population and the fast transfer of modern technology to the developing countries.
You can imagine how such monumental economic shifts mean to the young generation world over. This is a change of enormous importance where India and China by the year 2050 will constitute 50% of the global GPD, this is a monumental switch in terms of economical power.
In the year 2000, one billion middle class people were in the rich countries and half billion people were in the developing countries. By the year 2030, 2 billion middle class people will be in Asia (one billion in China by 2050). Africa will grow from 850 millions people in 2000 to two billions people 2050. By the year 2050, the average income in Africa will be 2000-3000 dollar per capita, for China and India will be between 30 000 and 40 000 dollar per capita, and for the countries in the rich world (US and Europe) will be between 90 000 and 100 000 dollar per capita.
Africa is a continent that is not any longer isolated, it is not a place where people are not well informed as information is passing and moving very quickly. Much trade and business in China and India is geared towards Africa.
These tectonic changes have monumental impacts on the young generation and they have to think very carefully how to face the global transfer in economy, production, services and technology. Education figures for the year 2007, tell us that 110 000 Chinese and over 100 000 Indians were studying in the US, while only 11200 Americans were studying in China and 2800 Americans in India. But, these figures will experience dramatic changes in the future because the mentioned major shifts in economy, production, services and technology.
The western countries were able to stay ahead because of (1) manufacture and that was taken away and moved to Asia; (2) service industries that first moved into the western countries but is moving out again to Asia by their gradual dominance in the service sectors; (3) technology where the west were able to stay ahead, but now the technological advance is being shifted as well to Asia. The challenge is now what is left for the west to do??
Necessity is the mother of invention. Where energy lacks there is much concern about finding it and using it with the most sustainable manner possible. This is why Iceland is among very few countries in the world where Renewable Energy Resources are managed with the best possible sustainable solutions. It is, also, possible that the availability and affordability of renewable energy in Iceland attracted Scandinavians to settle in Iceland sometime around the second half of the 9th century as in ancient cultures people sought living there were good possibilities to secure “WE-resources”. i.e. water and energy resources. The necessity and needs for survival are essential drivers for inventions and advances in science and technology. It is interesting to mention that 100% of the electricity production in Iceland is produced from renewable energy resources, i.e. hydropower and geothermal heat. Furthermore, 85% of total primary energy supply in Iceland is derived from domestically produced renewable energy sources.
So, we have something to learn from this country that in addition of being in the icy part of the world has a very long dark winter season. However, Iceland is not as cold as Minnesota (USA), for example, and not as dark as Tromso (Norway). That doesn’t mean that Island is some tropical paradise though.
The dream of any nation is to provide its population with safety and security especially in most critical situations with severe disasters, tragedies and collective nightmare arising from fear, insecurity and uncertain future. The nuclear disaster and the national tragedy from Fukushima nuclear accident in Japan demonstrated how collective efforts, the neat national planning along with continuous and intensive hard-work brought about safety and security for almost all the population in Japan.
An amazing awareness and responsibility on all levels for the DE-COMTAMINATION of every single inch or centimeter of land, houses, school, hospitals, roads, trees and practically all environmental compartments. A national DE-COMTAMINATION strategy if followed by other nations much of pollutions and waste problems can be solved. Successful sustainable management is about providing future generations with secure and safe living conditions, it is a collective discipline, awareness and responsibility from all for all and by all including preparing and fostering future generation for how to handle national disasters and severe tragedies.
Geothermal energy is among potential “semi-global” natural energy resources, as it is only accessible and affordable in economic terms in hot and limited areas around the globe. It is also considered to be relatively user friendly, more energy-intensive in comparison to solar energy, has less threats in case of technical failure as compared to nuclear power, simple and more safe production-technology in terms of drift and above all more durable and lasing natural source. It is indeed a form of “fossil resource” as being a remainder from the Big Bang. However, unlike energy produced in stars such as in the sun (solar energy) through fusion-reactions, energy in planets such as the earth is being produced through decay processes of the primordial radio-activity. Actually, without the embedded sources of heat in the earth’s body, i.e. the energy emitted through the decay of natural radio-activity, e.g. the radio-active members of the U and Th series, and many other radio-active isotopes of other elements that can have half-lives much longer than the age of the universe itself, e.g. Te-128 of half-life of 2.2 exa millions (billion billion millions) of years.
The most interesting issue in energy production and use is that water in always involved in these processes with two main impacts what concerns WE-resources, i.e. Water and Energy. For energy we are consuming more energy resources and thereby less we are gradually facing less access to energy resources and as a consequence increasing prices of energy production. As energy production, use and consumption create more waste and pollution as well as bring water to more open systems and interactions there is continuous and gradual degradation in water quality and thereby increasing threats to all life forms on the earth.
So, production and use of geothermal energy can be, also, associated with negative impacts on water resources, environment and bio-diversity.
An important aspect for appropriate implementation of Sustainable Technologies is Sustainable Management. The fundamental question is How Sustainable is Sustainable? And what are the most appropriate solutions for Achieving the Best Socio-economic Sustainability? Among strategic long-term and large-scale policies for the MENA region, where arid and semi-arid conditions prevail, is Water Management because of its impacts on all involved sectors (energy, industry, agriculture and environment) in this region, life quality and bio-diversity. Unfortunately, existing literature still lack appropriate long-term and large-scale sustainability solutions as being based on “Business as Usual” without consideration to other possible and yet feasible alternatives.
Seawater desalination constitutes an important source for water supply for all sector activities and the population in the bordering the Arabian Gulf, the Mediterranean Sea, and the Red Sea. Desalination has advantages and disadvantages that may depend on the region, location, technology, impact and amount of fresh water production. Apart from the energy requirements for desalination, there are also other negative impacts in terms of waste management, fish production and quality of marine life in general. However, these impacts can be mitigated or even eliminated, by solutions other than those currently available.
Increasing pressures on natural resources, in particular availability, accessibility and affordability of Water and Energy “WE”-resources, require Sustainable Management Policies that consider shaping and integrating Sustainable Technologies to meet the growing needs for large-scale and long-term transformation to New Sustainable Life-styles. Unlike, in ancient civilization where population settlements were created at/around fresh surface-water bodies, e.g. rivers, lakes and deltas, future settlements are likely to grow faster at coastal regions “Hydroponic Coastal Colonies” and non-traditional living areas with limited fresh-water resources. Agricultural production may not require land to the same extent as in traditional farm communities; modern technology will allow more Sustainable Cities to grow on coastal areas as well. However, climate change threats for increasing sea-water levels have to be taken in consideration, what we have learned from the past safety and protection measures are always part of any successful socio-economic developments. The future is bright by innovation and not by imitation.
Global warming is not only a matter of increasing temperature, ice melting, increasing sea water level and enhanced abnormalities in weather conditions. Changes in temperature, though might seem, as little as few degrees, will bring about major changes in the functioning and metabolism is global aquatic, ecological and land-water systems. Fish population in world oceans and seas will suffer major dynamic changes, in term of population, species and catch composition. Fish species will be forced to large-scale migration to adapt themselves for new living in suitable waters and some fish species are expected to disappear. Such major changes in fish species will also have other impacts on global ecology of other animal species.
Water is the natural environment for the life quality of fish and hence water quality is of prime importance for fish production and the quality of fish as well. Even in aquatic eco-systems, one can simply say “what goes around comes around”. Understanding how to improve the conditions in fish farming in terms of production and quality have very much to do with understanding the functioning and metabolism in natural aquatic systems. There are key issues that are essential to be understood about water quality in aquatic systems (fresh, brackish and marine), in particular the physical (e.g. density, stratification and mixing as well as turbidity, mineral particulate, light transmission) and chemical (e.g. pH, solubility of gases such as oxygen, carbon di-oxide, ammonia, salt concentration, dissolved matter, organic and inorganic particulates) properties and characteristics in these waters at different temperatures. The physical and chemical conditions of water determine to large extent the water quality status, along with toxic anthropogenic compounds that originates from pollution and water from industrial, agricultural and household sources. The impacts of all these conditions, factors and properties on water quality, the response and feedback effects on fish in terms of production and quality are to large extent summarized in the following document, it can be used as a guide for fish farmers.
The rosy festival of continuous prosperity growth has recently been challenged by the theory of “Peak Oil”, which concludes that the amount fossil energy (oil, gas and coal) being extracted from the earth will shortly start an irreversible decline. We will be increasingly dependent on other energy sources to power our civilization, if not to say our long-term survival.
Assessment of the global energy resources, consumption and trends in global energy-mix with consideration to increasing global population shows that energy per capita will decrease. This will have negative impacts on GDP “Gross Domestic Product” and probable escalation in the costs of raw material, e.g. fertilizer and the diesel fuel or electricity for water pumps that are essential for agriculture and production of food. We will be, therefor, moving fast not only towards energy poverty but also towards global economic recession, pushing many countries and population towards increasing poverty, e.g. shortage of water, food and housing.
