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.

Category: Agriculture & Farming
Farming and animal husbandry are typical activities in rural communities and the motor of economy especially in the developing countries, e.g. Asia, South America and Africa. Supporting these basic activities is imperative for achieving sustainable socio-economic developments in many developing countries. Successful urbanization strategies around the world are very much related to supporting rural communities and integrating them with the rest of society through effective management of farming and animal husbandry sectors.
Increasing consumption of water for agriculture and food production, as consequence of feeding an ever growing world population, is causing geographical expansion of “Peak Water” around the world. Lack of sufficient water for irrigation and food production is already turning vast regions of land to “virtual deserts” that gradually and eventually will develop to permanent deserts through an accelerating degradation of soil quality and erosion of top fertile soils.
Also, the increasing decoupling of “surface water – groundwater” through the action of “Peak Water” in combination with degradation in soil quality, i.e. decreasing organic content “mineralisation”, will force increasing water-consumption for irrigation with gradual development of “Virtual deserts”. Furthermore, excessive use of surface water and groundwater pumping in combination with global warming will enhance expansion of dry land.
The Sahara or the Great Desert, in Arabic Al Sahra al-Kubra “الصحراءالكبرى” is one of major deserts on planet Earth, i.e. landscape that receives very little precipitation, rain or snow, less than 250 mm per year. It is as big as the USA and its sand can burry the whole world 20 cm deep. Desert land does not necessarily mean sand and sand dunes; many deserts are rocky surfaces as well. One third of the earth’s surface is desert lands that exist in polar, subtropical, cold winter and cool coastal regions. Deserts have no surface streams because of rapid evaporation, transpiration (by plants and subsequent release to atmosphere) or/and infiltration into the ground. Deserts have unique fauna and flora that are adapted to the harsh climate and environment conditions, i.e. intense sun, limited precipitation, severe temperature ranges, dry wind and low humidity.
The Sahara Desert is located in subtropical North Africa and it is the hottest place on the planet. The mystery of what created and changed the Sahara desert has revealed a turbulent past. The African tectonic plate collided with Europe and what was a huge sea turned gradually to land, with the Mediterranean as remaining sea, many million of years ago. Finding whales in the desert is not a climatological story but rather a geological evolution. Indeed, the Sahara has the highest fossil remains in the world, almost all of them are marine animals such as those found in Wadi Al Hitan, Egypt “Whales Valley”. The reconstruction of the evolution and the history of the Sahara were made possible through the remaining fossils of sea creatures in the desert itself along with geological information from deep sediment cores. Sediment cores are excellent archives for obtaining historical, environmental and climatological information. Whale bones in the desert showed that 40 millions years ago the Sahara was a sea bed, deep ocean sediment cores containing wind blown sand revealed that sea water dried up three millions years ago. Freshwater shells buried in sand showed that 90 000 years ago the “wobbles” of the earth’s axis (http://www.ncdc.noaa.gov/paleo/milankovitch.html) created huge freshwater lakes and rivers and turned the Sahara green every 20 000 years. Ostrich eggshell, used by prehistoric settlements for manufacturing beads, indicated that just 7000 years ago the Sahara enjoyed its final burst of life before returning into desert.
The story of the Sahara showed that it wasn’t always a barren wasteland. Life was not static, it could shift, change, evolve and it can bloom again into green terrain, i.e. in the distant future. Ground penetrating radars showed that there are huge freshwater lakes “groundwater” under the surface of the Sahara Desert. Such fossil water can be million of years old. This gives hopes for turning the desert to green land by being reclaimed for agriculture and farming. Nubian Aquifer (Egypt, Libya, Sudan and Chad) is an example of such fossil water and is already in use. Fossil water is non-renewable resource, can only be used once and is sufficient for a short period of time depending on consumption, probably can last something like 100 years. After being consumed the desert has to wait for another 15000 years before once more earth “wobbles” turns it green again.
Note. The earth wobbles in space makes it tilt around its axis on a cycle of 41 000 years with introduction of changes in the seasons. More tilt means more severe seasons, i.e. warmer summers and colder winters; less tilt means less severe seasons – colder summers and milder winters.
This new chapter of history that tells the story of the past turbulent landscape of the Sahara gives interesting information on how the earth and desert was made.
New research data is pointing towards population peak around 2055, about 8.7 billions, followed by decline to 8 billions by 2100 (http://www.cnbc.com/id/101018722). However, according to data given below peak population could occur by the year 2070 when the population might be 9.5 or 10 billion. Previous data by the United Nations “UN” foresee further rise until 2100 to reach 10.9 billions with no peak population.
The carrying capacity of planet earth is a very much-discussed topic with many different scenarios and predictions. However, increasing amount of data have shifted towards more clear trends a converging world population towards a peak around 2050 due to the declining of global fertility. All developed, less developed and least developed regions show declining fertilities that already started around 1960. The period of continuous increase in global population because of increasing average human life span and decline in human mortality will soon be over.
Decisions of what type of energy resources we should invest in have long-term and large-scale impacts on the ecological quality of water and soil fertility. One issue, which is not very well searched, is the impacts of hydropower on the ecological quality of water that gives rise soil fertility. Both the ecological quality of water and soil fertility are very important for biodiversity and food production.
Hydropower is by definition a major interference in the natural hydrological cycle of surface water where erosion at up-stream high-land regions is essential process for promoting soil fertility in river catchments and river deltas in down-stream and low-land regions. In previous cases, e.g. the Aswan high-dam, the natural fertility at down-stream and delta areas was mitigated by heavy use of artificial fertilization. Artificial fertilization will not last for long-term as it is a non-renewable resource in addition to the long-term and large-scale environmental risks associated with it in terms of use and production.
In most of the energy debates the focus, so far, has been on reduction of carbon dioxide “green-house gas” so as to minimize the effect of global warming and its associated impacts. That is of course necessary but at the same time we have to consider other major impacts on the water cycle because of “Water-Energy Nexus” and in this context we have to take such aspects while we are about to implement policies for the use of “oil sand” or tar sand”. “Oil sand” or tar sand” is another case where in addition to risks for increased carbon dioxide emissions, there are clear negative impacts on water and ecological qualities.
Though the negative impacts of hydropower on ecological water quality and soil fertility may not be of the same dimensions as the benefits from hydropower, such impacts have to be taken in consideration for optimization of overall long-term and large-scale uses of “Water-Energy” resources. What we need to do is to have appropriate “Environment Assessment Analyses” and “Sustainable Actions” in place, so as to be prepared to deal with the growing degradation of water and ecological qualities.
World Resources Institute “WRI” has recently evaluated, mapped, and scored water risks in 100 river basins of 180 nations around the world. Assessment is carried out for the first time on country-level with consideration to area and population. In this research 36 countries face “extremely high” levels of baseline water stress. This means that more than 80 percent of the water available to agricultural, domestic, and industrial users is withdrawn annually — leaving businesses, farms, and communities vulnerable to scarcity. Baseline water stress, used as an indicator, measures how much water is withdrawn every year from rivers, streams, and shallow aquifers for domestic, agricultural, and industrial uses.
Analyzing water risk at the country level is important as such information is highly relevant for country’s economy, environment, and communities. Though water data is usually collected and reported at local geographic scales, water-related decisions and investments are often made at much larger scales, thus requiring country-level information.
Extremely high water stress can be successfully managed such as in the case of Singapore. The country is densely populated with no freshwater lakes or aquifers, and its demand for water far exceeds its naturally occurring supply. Singapore invests heavily in technology, international agreements, and responsible management, allowing it to meet its freshwater needs. Advanced rainwater capture systems contribute 20 percent of Singapore’s water supply, 40 percent is imported from Malaysia, grey water reuse adds 30 percent, and desalination produces the remaining 10 percent of the supply to meet the country’s total demand.
An important issue in this respect which is still lacking in many parts of the world is spatio-temporal water quality maps where pollution sources, both point and diffuse, are being identified. This is of importance for better conservation and protection of water resources as well as for building up solid monitoring programs for assessing the status of surface-/ground-water and associated eco-systems. Such programs give access to base-line data of natural levels of pollutants, provide bases for early-warning systems and facilitate rehabilitation actions
Nomads, 30-40 millions in 1995 around the world, roaming around and moving from one place to another for pasture or hunter-gatherer is a fast disappearing life-style. Reindeer have been herded for centuries in polar and sub-polar regions, horses remain national symbols in Mongolia and camels are still the perfect choice in the Sahara. After the industrial revolution “mechanization” and with increasing dependence on fossil-fuel, urbanization became “magnets” causing considerable drainage of people to technology and modern life, even without basic knowledge about the requirements and threats of the new life.
“There’s no place like home”, but with the advance of science and technology the definition of home becomes much different in particular in the era of globalization and the Internet. The choice between staying home and being drained to new life-styles may create conflicts between generations and communities or at least cause separation and fragmentation in families.
The weather in the polar mountains can turn in just a few minutes and at the artic circle conditions can be extreme. The ways of life, learning and even childbirth are often intense. People living in the tundra are accustomed to a nomadic life. Tents are their homes, food is basic, and the deer is king. They don’t watch TV or don’t use internet. Children do go to boarding schools, but not all parents are in favor of them. A well-known writer and teacher created her own alternative education for the children of the tundra as she believes that a good education should be based on the essential skills needed to survive in the artic far north. She explains that our constitution clearly says our indigenous children must have free education but it doesn’t say free life care. In schools everything is done for the children and later on they face life without to know how to do ordinary things, as they don’t have that knowledge when they leave schools. Children become gradually separated from their roots, loose ties with other generations and when graduated from school they have to decide between going to higher education or back to the tundra. What to choose when they already separated from home and are not able to establish roots at home?

This is a lesson to be learned about how previous generations survived the extreme conditions on earth, i.e. somewhat similar to the environment of the ice ages.
Agafia Lykov born 1944 in the Siberian wilderness, she has a very unique and rare story. Today she is still remaining alone, isolated in one of the most extreme and inhospitable environment on our planet. She is surviving steadfast in her seclusion in the Sayan Mountains, 160 miles away from any other sign of civilization. Agafia’s family that escaped persecution and moved to Siberia in 1936 became famous in 1978 when Agafia was discovered by a team of Russian geologists. This event marked the end of their isolation and Agafia’s family became famous in Russia as the family of Siberian hermits who didn’t know that World War II took place!

The economic benefits of phosphorus fertilization on crop production are well documented, also its importance for food security but is phosphorus fertilization free from risks and threats? or is too much of a good thing can be detrimental? If so, what are the threats and risks that are associated with the excesstive use of phosphorus.
Soil degradation is a worldwide problem especially with the inceasing damming of rivers around the world due to the need for hydro-electric power. Natural erosion that brings fertile soil to the low land and deltas are being halted as eroded materials are forced to accumulate behind artifically engineered barriers, i.e. the dams. As a consequence of damming of rivers huge land-areas loose their natural fartility and artificial fertilization is required for mitigation. This is, indeed, on short-term perspective both economically and environmentally expensive, and out-come are disastrous what regards the long-term and large-scale consequences.
Excessive use of phosphorus in agriculture for food production has negative impacts on water quality of aquatic systems (rivers, lakes and marine coasts) and groundwater due to increasing levels of P in aquatic systems that cause “eutrophication”, decreasing levels of oxygen and gradual decrease in fish productivity. Degradation of water quality of groundwater is associated with increasing agricultural waste/run-off. In all cases, there are associated costs for mitigation, rehabilitation and purification of water. http://pubs.ext.vt.edu/424/424-029/424-029_pdf.pdf
Another critical issue in securing our future food is indeed missing from the global policy agenda: we are running out of cheap and readily available phosphate fertilizer on which world agriculture is totally dependent. Supply of phosphorus from mined phosphate rock could ‘peak’ as soon as 2033, as phosphate rock is a non-renewable resource becoming increasingly scarce and expensive. http://www.soilassociation.org/LinkClick.aspx?fileticket=eeGPQJORrkw%3D
“Sustain-earth.com” will represent an alternative and sustainable approaches for fertilization with several benefits over artificial phosphorus fertilization that can very well replace it. This alternative is WE-saving, i.e. can save both energy and water, it is environment friendly.

Rivers, lakes and deltas, and their catchments are major freshwater resources for the world populations. However, the increasing impacts of waste, pollution and sanitation during the past century, in particular after WW-II, caused major damage and degradation in many river and lake eco-systems around the world. We give here few examples of the most polluted rivers around the world.

Lake Victoria, the second largest fresh-water body in the world and a water resource shared by three East African countries, is an enormous water resource facing collective mis-management on several levels. Lake Victoria is under considerable pollution pressures causing softly and steadily killing of its bio-diversity in addition to a real risk for drying-up from “global warming”.
An example is Jinja town, population of 300 000 people, that is rising after so many years of decline to claim the glory it lost so many years ago. However, the time is running out not only for the town and its population but for the whole water body of Lake Victoria. There is an accelerating pollution, abuse of environment and water resources due to limited access to waste and solid-waste treatment from industry, agriculture, household, rubbish damp and sanitation. Many industrial (more than 70 factories in Jinja only with high pollution incidents) , agricultural, household activities are releasing huge amounts of waste and pollutants to Lake Victoria.
The fishing, transport of people and goods to the main land and other public services suffer from random management, fragmented policies, and lack of collective protection and management actions. Fish population is declining as consequence of the damage the food-web dynamics of the lake and the natural functioning and metabolism in the lake because of heavy loads of nutrients, pollutants and siltation. Over-fishing of the so-called “fish-of-choice” a small fish lower down in the food-web that is destroying the natural balance of the food-web and causing the collapse of the overall fish-population dynamics.
Poor infra-structures and water drainage systems from forest, agriculture, household and sanitation along with erosion and re-suspension of sediments due to man-made and animal activities are causing excess delivery of nutrients, accelerating “eutrophication” and decreasing levels of oxygen and thereby death and increasing prices of fish. The degradation of water quality will, also, force gradual and rapid increase in the proces of clean water.
Waters around the world are facing a new era of threats with accelerating disasters, pressures and constrains due to global warming, waste and pollution. Water scarcity and degradation in water and ecological qualities are creating crises for wild habitats and human civilizations. Many seas, rivers, lakes, and underground water reserves around the world are either lost or losing their aquatic resources with serious impacts on the livelihoods of hundreds of millions people, animals, farming, lives, electricity, and threatening further environment and climate changes.
Chinas Salween River, Europe’s Danube, South America’s la Plata, North American Rio Grande, India’s Ganges, Pakistan’s Indus, Africa’s Nile and Lake Victoria, Australia’s Murray Darling, Southeast Asia’s Mekong-Lancang, China’s Yangtze due to dams, over-extraction, overfishing and climate change. In addition to the threats of global warming and human activities; waste and pollution from industry, agriculture and household further worsen the quality of waters.

The Nile Basin Countries are facing two major long-term and large-scale threats that can lead to the total collapse of the water resources in the whole Nile system, i.e. from the very sources at its origin “up-stream” to its final fate at the deltas “down-stream”. These major threats are related to climate change “global warming” and environmental degradation because of waste and pollution (from energy, industry, agriculture and household). To deal with these major threats, i.e. mitigation and solutions, the Nile Basin countries need to develop and implement sustainable management strategies/policies. In this context, achieving sustainable socio-economic developments in the Nile Basin region, which indeed applies also to the other parts of the MENA region, requires coupling public awareness, education, science and technology programs to society, population and markets needs.
Unfortunately, there are growing global fear about the quality of seafood and fish that are either wild in polluted waters or farmed in toxic waters. Such unfit fish for eating, i.e. with high levels of toxic pollutants, is available in the market as control instruments are either ineffective or non-existing.
For different reasons the water quality where fish is grown is facing considerable pollution threats because of acute water shortages, water supplies contaminated by sewage, industrial waste and agricultural runoff that includes pesticides. These pollution threats are accelerating because of increasing pressures on water resources and unavailable/limited regulations for fish farming in many regions around the world. Farmers, for example, have coped with the toxic waters by mixing illegal veterinary drugs and pesticides into fish feed, which helps keep their stocks alive yet leaves poisonous and carcinogenic residues in seafood. Many people started to work with fish faring without enough knowledge and in areas with little or no control. This introduces enormous health threats to consumers where environmental degradation has become a food safety problem. Indeed, the long-term risks of consuming contaminated seafood could lead to higher rates of cancer and liver disease and other afflictions. “Sustain-earth.com” will follow these issues and give further information and details on these issues.
The accelerating consumption of WE-resources “Water and Energy Resources” in the MENA region has huge negative long-term and large-scale impacts on achieving sustainable socio-economic developments in the whole region. The same threats are emerging in the Nile Basin region. Effective large-scale and long-term solutions are urgently required for developing and implementing WE-saving technologies in all society sectors and on all levels.
An important question for achieving sustainable socio-economic developments in any nation is: what is the limiting factor, is it water or energy? Currently, lack of access to clean water and sanitation kills children at a rate equivalent to jumbo jet crashing every four hours, this is equivalent to 3.4 million people die each year from water, sanitation and hygiene-related problems. Almost 1 billion people lack access to safe drinking water, mainly in the developing countries; the problem will still worsen as 70 percent of industrial waste is dumped untreated into waterways. The so-called emerging economies are, also, facing an accelerating threat from mismanagement of water resources that on the long run will be the most limiting factor for achieving sustainable socio-economic development.
China isn’t an exception, with its 22% of the world’s population, an access to only 5 percent of global water resources and an estimated 300 million people that lack access to safe drinking water. According to the Ministry of Water Resources in China, if China continues to consume and pollute at today’s rate, water demand will exceed supply in less than two decades. The past decades of rapid development, massive construction of infrastructure and huge industrial developments resulted in huge pollutant’s spill untreated into waterways. An estimated 50% of groundwater in cities, 77% of 26 key monitored lakes and reservoirs and 43% of 7 major river basins are considered unfit for human contact. Meanwhile, 19% of monitored rivers and basins, 35% of lakes are reservoirs are considered unfit even for agricultural or industrial use. These effects are related to China’s huge needs for energy and the associated “energy-water” nexus, e.g. 96% of China’s electric power requires water to generate, and 47% of electricity is consumed by water scarce provinces. Agriculture is by far the largest consumer of water at 62%, and the largest polluter, with pesticides and fertilizers responsible for about half the contamination of waterways. Soils are, also, facing great degradation, the average level of organic matter in soil is now 1-5% for northeastern China’s arable land, compared with 8-10% in the 1950s. A report published in 2007 by the World Bank and the Chinese government estimated the combined health and non-health cost of outdoor air and water pollution at approximately $100 billion a year, or about 5.8% of China’s GDP. Water pollution, meanwhile, worsens China’s severe water scarcity problems, with the overall cost of water shortages estimated at 1% of GDP.
Climate change has, also, negative effects in form of growing desertification and prolonged droughts in agricultural regions nationwide with impacts on drinking water and livestock as well as water levels in some of the countries major hydropower producing regions.
Global warming whether is a natural climate change process or artificial man-made climate impacts have enormous impacts on our choices to select secure and safe solutions of human energy needs. Also, pollution and waste products from energy production and use, including accidents and disasters, makes it difficult to keep land in tact for agricultural and for suitable household uses. Modern threats from climate, waste and pollution dedicate new realities for humans in terms of limiting the diversity for appropriate, safe and secure life on earth. The road for achieving sustainable socio-economic developments becomes more difficult once we overload it with more “time-bombs”.
Worldwide water governance has been challenged on several levels from local up to international though the existing forces are beyond human control, e.g. growing human population, increasing diversity in economic activities, enhanced competition on water resources, threats of climate disruption on water balance and availability. Sustainable management of natural resources is facing challenges in particular policy-making, the implementation of laws, interpretation of international treaties and conventions. Examples are the trans-boundary water issues and disputes between upstream-downstream countries due to divergence in utilization of water resources for power generation, industry, agriculture and household uses. Water scarcity and security are typical issues in the MENA region and have caused disputes in the Nile Basin and Israel-Palestine area. This is, also, the case in other parts of the world, e.g. between India and Pakistan.
Other challenges are: affordable access to safe drinking water as a human right, e.g. sanitation and health issues in Sub-Saharan Africa; the needs for ways to measure access to improved water and unimproved water; the push to privatize water resources to drive efficiency and water trade; drought management and impacts of climate change. In global perspective water as a human right is not totally agreed upon, e.g. by the US and others international donors and what concerns affordability there are still more efforts to be done.
A panel discussion on contemporary challenges is given here on the sustainable use of the world’s freshwater resources, and the effectiveness of international law, e.g. international human right law, international environmental law and others, to meet existing challenges.
Among the most important indicators for life on earth are air and water qualities with poor qualities of air and water it becomes difficult, even impossible, to sustain life in any form. In some places in the world abuse of the natural resources, e.g. blind exploitation, production and use, have caused serious degradation and enormous damage, of natural environments. Exploitation, production and consumption are associated with environmental, ecological and human costs in form of “environmental, ecological and health degradation” and if such costs are not accounted for we will have negative sustainability balance. With gradual pile-up of such environmental, ecological and health debt, as is the case in the given examples, there would be no places on earth for suitable and sustainable life.
Svante Arrhenius was the first to claim global warming to be due to “green house” gas emissions in 1896. A Swedish scientist who suggested the effects of fossil fuel on enhanced global warming. This finding was a by-product of research on the possible impacts of carbon dioxide on the great Ice Ages by Arrhenius and Chamberlin. The topic was forgotten for a very long time and it was thought than human influences were insignificant compared to the natural warming of the earth’s atmosphere by solar activity and ocean circulation. The oceans were thought to cancel out the atmospheric pollution by being carbon sinks and that water vapor was seen as a much more influential greenhouse gas.
Since 1940’s research on carbon dioxide started to expand with developments in infrared spectroscopy and impacts of atmospheric carbon dioxide and water vapor on the absorption of heat. In the 1950’s and 1960’s it became clear that the ocean could never be a complete sink of carbon dioxide and the atmospheric lifetime of carbon dioxide was estimated to be about 10 years. Quantitative data that the oceans absorb nearly a third of man-made carbon dioxide was made possible by carbon-14. This radio-isotope can trace the time-space dynamics of atmospheric carbon dioxide, i.e. both natural and artificial.
In 1950’s and early 1960’s Charles Keeling used the most modern technologies to produce concentration curves for atmospheric carbon dioxide in Antarctica and Mauna Loa. The curves showed a downward trend of global annual temperature from the 1940’s to the 1970’s and it was first feared that a new ice age might be near. In the 1980’s, the global annual mean temperature curve started to rise and began to increase so steeply in late 1980’s, an upcoming new ice age was strongly questioned and the global warming theory began to win terrain fast. In 1988 it was finally acknowledged that climate was warmer than any period since 1880 and Intergovernmental Panel on Climate Change (IPCC) was founded. In 1990’s scientists started to question the greenhouse effect theory, because of major uncertainties in the data sets and model outcomes. So far not many measures have been taken to remove all the uncertainties in climate change. It is a global problem that is hard to be solved by single countries. While accepting the existing uncertainties for the time being we can’t prevent major climate and weather disasters to take place. How shall we mitigate the increasing frequency and magnitude of climate and weather disasters whether they are natural or artificial? Though the situation can be similar to earth quakes, where we know they do take place but we do not know with certainty when, where and what to do to safe/protect our lives. Climate and weather disasters have much more devastating and irreversible impacts and threats on all life forms on the earth and can take place on much more larger scales.
