Category: Categories, Posts & Discussions

This BLOG “sustain-earth” is an In-clusive, Inter-active, Inter-disciplinary and Inter-sectorial platform to implement “Sustainability and Applied Sustainability” in all sectors, on all levels and anywhere. It is, also, a market-oriented platform for transforming “Sustainability and Applied Sustainability”, from individual, narrow and fragmented understanding to a holistic and applied prospective. The search of man for secured living confronted with fundamental life processes on earth and resulted in major threats endangering the land-water resources and the very survival of life.

The “BLOG” is constructed in two parts: Part (1) is a “theoretical and knowledge-based one”; and Part (2) is a “practical and applied one”. Both parts are inter-related and supplement each other where Part (1) “Categories, posts & Discussions” explains the theoretical background upon which Part (2) “Pages & Note-board” is based. Both parts are spanning over all national sectors (private, public and governmental) and involve, also, inter-governmental organizations and relevant international bodies. Furthermore, the structure and built-in dynamics of the “BLOG” seek the integration of individuals, groups, companies, organizations, communities, societies, ….. etc. on both horizontal and vertical levels. The motivation, goal and vision are to bring about coherent sustainable systems through linking together all building blocks. Sustainability, i.e. concepts and knowledge therein, is being explained in Part (1) while Part (2) is devoted to more Applied and practical issues for production, communication and services.

Through its Editorial Board and Guest Bloggers and contact points, the BLOG is acting as “Open Access” instrument for coupling education and research with market and society needs, and thereby supporting professionals, including young ones, for creating, improving and up-dating “Career Development Plans” to suit an ever dynamic and changeable labor market. It is an instrument for enhancing public awareness, promoting capacity building as well as for supporting the development and management of human resources and infra-structures for quality services in public and private sectors.

The Unique Cultural Mosaic of the Growing Africa.

With flourishing economy in Africa, and the vision of young people for transfer to democracy and a better life, innovation in music, fashion and art are gradually penetrating and diffusing in the unique cultural mosaic of the growing Africa. An example is the Ethiopian music that combines different cultural and emotional backgrounds, a needed positive energy for fueling the populations towards the new future.

Global Water Resources in the 21st Century Versus the 20th Century

Climate Change and the expected impacts of Global Warming on global water resources will have pronounced effects worldwide in the 21st century. To see any change some references must be used and in this case as explained here the 20th century will be used reference for comparison. Among key processes in the global water cycle that are undergoing dramatic changes in dynamics and rates are: evapotranspiration; soil moisture; surface water flow and ground water levels. Changes in the dynamics and rates of these  processes will have direct and indirect effects on the vegetation cover, forest, agriculture and farming as well as remarkable impacts on the global water supply with feedback effects on agriculture, industry and basic human need including drinking water .

Lessons to be Learned – Fall of “Berlin Wall” and “Petro-Dollar Wall”

Walls, in this case “geo-political” and “geo-economic” walls, are built for some reasons, raised and kept in place by some powers. However, with time they get gradually eroded. In this process of erosion, it is not if they will collapse or not but rather when the final collapse will be a reality. The collapse of huge “geo-political” and “geo-economic” walls is not of a small-scale and an over-night process. In any case, the suffering from the collapse has enormous large-scale and long-term impacts as the generated collapse and ruins shake and hits multiple of populations across many borders and for many years. Germany is an example of what “geo-political” walls can bring to populations and how the ruins after disastrous wars, raising and falling walls can be restored. In this context, “geo-economic” walls are not exceptions in history and what is happening in the MENA region is just a playback of history.

Lessons to be learned – Mercury Pollution in Fish

Mercury is among toxic pollutants with harmful effects on humans. Mercury in aquatic eco-systems originate from atmospheric pollution and ends up in aquatic systems where fish get exposed to different levels of mercury concentrations in water. Direct injections of pollutants, involving other types, can occur also from agriculture, industry and household. Here are simple facts on mercury pollution in aquatic systems.

https://www.youtube.com/watch?v=xRqAS4Eow-c&feature=youtu.be

 

In the next video we are demostrating how pollution gradually degraded the water quality in natural aquatic systems making then of less recreation and economic value.  Water quality monitoring, assessment and regulations are essential management instruments for protection and preservation of natural waters against all types of pollution. Protection of air and water qualities have feedback effetcs on health of humans and safety of the environment, they are also imperative for achieving sustainable socio-economic developments.

Fish Can Accumulate and Bring Toxic Pollution Straight to Your Mouth

Many pollutants are injected to the atmosphere and may have long-distant trajectories around the globe, e.g. particulate matter (PM), green-house gases (GHG), acidic oxides (sulphur and nitrogen), , volatile organic compounds (VOC), persistent organic pollutants or “polychlorinated biphenyls” PCBs, ozone, heavy metals (lead, mercury, cadmium, …. ), radioactive pollutants. In addition to degradation of air-quality as is the case in big cities and heavily populated regions, the major part of these pollutants get washed out by rain and join the hydrosphere and thereby enter the aquatic systems, e.g. oceans, seas, rivers, lakes.

Faroe Islands have long old whaling tradition, pilot whales, and whaling is part of people’s culture and among the main sources of food. However, pilot whales have low levels of mercury and PCBs toxics. It is well known that mercury in high doses could cause severe brain damage, however at low or smaller doses over a long period of time can also cause damage to the body. 2000 children were tested for the effects of chronic low level mercury exposure. It has been found that such exposure affects baby’s brain causing deficits in development and feedback impacts on regulations of the heart.

Pilot whales have long-life span and by being highest up in the food chain, they also feed on other fish, they accumulate many pollutants PCBs and metal mercury and thereby whale meat carry toxic compounds. In this context, these small North Atlantic islands grapple with how to maintain a centuries-old tradition in the face of modern environmental and political circumstances.

Whales – Conservation of Bio-diversity is Key for our Survival.

Evolution of the global bio-diversity and the social life in natural eco-systems around us has long-standing histories. Yet our knowledge is not complete and many secrets remain to be mostly unknown.

Sperm whales are the most hunted species, then for generations it took a great many men to kill few whales but the technology has now reversed the problem. The problem before was to find sperm whales and kill them, but the problem now is to find how many sperm whales than can be killed without endangering the species. In a world full of hunger production doesn’t slow down for science, the only means to find out the proper answers. The ultimate fate of the whales and the industry depends on the accuracy of science to shape sustainable management policies in an ever-increasing complexity and fragmentation of “industry-society” sectors.

Sperm whales have the largest brain of any animal and probably dive deeper than many other mammals. We know little about why they sing, we even don’t know how, how much they sleep and even if they need to sleep at all. They have complex social life of which we know very little about. 

Biologists collect much raw material for the construction of their re-productive cycle. In which, the age of the whales are key component to follow the biology and ecology of whale populations. Sperm whale carries its life calendar in their teeth. Teeth, in this context, are true age-indicators of the whales as they consist of alternating “drack-light” layers. When the age is known, it is then correlated with other information from the soft parts of whales and by computer simulation (size, range and reproductive capacity for various whale populations) knowledge on, how many whales can be safely harvested, can be gained. Biologists make the statistics but the whaling industry take care of the rest.

In a separate “POST” we will tell more about the threats facing “pilot whales”

Whaling Industry in Early 1900 and Beyond.

I came a cross an old whaling film (in two parts) aboard U.S. ship “The Viola” from 1916 describing the hard working condition during the early years of the growing industrialization. The ships used for whaling were built even earlier, i.e. around 1850 or so. The whaling work required too much work, labor and the tools and techniques used at that time were simple or even primitive as judged by current western standards. However, these were the conditions and what was available at that time. This in addition to too long fishing journeys for little outcome; this is how people worked hard for getting their food and income at that time. All modern industrial technologies, including film-industry and ICT-based machinery that replaced difficult, ineffective and time-consuming man-power were gained mostly after WW-II, i.e. the later part of 1900. However, human struggle to get enough, affordable and healthy food will never end as there are always new pressures, threats and challenges. Education and research are always needed for better conservation and management policies.

Life in the Sea – A Source of Life for Many of Us

Humans are adapted for life on land only, we wouldn’t survive in water more than few minutes. Yet without life in aquatic systems, seas, rivers and lakes, many of us wouldn’t be a life at all and even vanished away longtime ago. But do we understand the secrets of life in fresh, brackish and marine water systems, from where fish (small and big) get their food, do fish drink water, if so how do food-chains look like in aquatic systems, does life exist in surface sediments. Do fish sleep, and while swimming how do fish navigate between stones, corals, identify there way, survive the dark environments in deep regions and at nights?  Do fish get sick, have diseases and eventually die, if so why and how?

Victoria Falls and its wildlife as Viewed by A Local fisherman

Victoria Falls is one the most beautiful waterfalls in the world. The wildlife and biodiversity of Zambezi River, feeding this spectacular waterfall, are unique in many aspects, i.e. unlike the other most famous waterfalls around the world.

However, what is the perception of a local fisherman, after being fishing for 69 years in the river, of wildlife and what does water and rain mean for the population and the animals in this enormous eco-system and life-factory.

Our understanding of the natural resources and life in rural Africa, and the habits, culture and needs of the local inhabitants is crucial for shaping future sustainability policies and for integrating rural regions with the increasing trends of urbanization in Africa.

Water-Energy Policies – Impacts of Damming on Eco-Systems and Socio-economies.

The increasing consumption of, and competition on, natural resources, in particular Water-Energy resources “WE-resources” is introducing new long-term and large-scale impacts on the sustainability of natural eco-systems and quality of life with major feedbacks socio-economic developments. Without credible environmental, social impact assessments and early-warning instruments, environmental compliance systems, rehabilitation measures and solid management policies can not be established whenever necessary. Impacts of large-scale manipulations of major river systems, as in this case, have rather slowly and unpredicted impacts on the environment and ecosystems. In addition, there are different regional consequence on re-location of population, water hydrology, farming and forests. Since the industrial revolution, and because of the ongoing globalization, there had been an accelerating consumption of energy and water resources. Currently, there are major threats, in some critical regions, resulting from transformations in energy policies, global warming, pollution and waste from industrial sectors as well as increasing consumption of natural resources.

Evolution of Earth – A Violent Struggle Towards Life.

The Earth, our unique home is just an immense ball of rock with proper mix of essential components for life at the surface, in the atmosphere, in water bodies, within and beneath the crust. It went through dramatic history of 4.5 million years with extreme environments and catastrophic transformations that eventually resulted in diverse forms of life. We now exist on its surface after a long struggle over ruins of fire, ice, violent seas, poisonous fumes and dead mass-extinctions. We are the survivals but yet for sometime, how long no one knows.

For thousands of years humans had no idea of the true age of the earth and the origin of the world. It is just in the past two hundred years scientists have explored and un-earthed its secrets through remarkable discoveries that led to tell the incredible story “How the earth was made”. It was a simple Scottish farmer “James Hutton” that triggered the generation of the enormous knowledge about the evolution of the earth. He spent years of own research with horse-expeditions around Scotland, to understand how rocks were formed from layers of sediments. Hutton finally found proves that the earth was very much older than what the Christian Church had been telling for generations. The Archbishop in the 17th century had calculated that the age of the earth was 6000 years old and indeed it was made on October the 14th on the afternoon. Hutton’s discovery was a turning point. It is now the rocks, who are the gays knowing the truth about age and evolution of the earth.

The journey of our blue-green planet began in a world full of fire and media made up of the early solar system with temperature similar to the surface of the sun. The origin of enormous heat of the earth, and the large-scale and long-time slow cooling-processes of the earth, is radioactivity. Based on heat evolved from the primordial radioactivity in the earth, uranium, thorium and potassium, Kelvin estimated that the earth would take millions of years to cool down. However, radiometric dating gives the correct age of the earth, i.e. using uranium found throughout the rocks on the earth and decaying into another element, lead. By measuring the ratio between lead and uranium trapped in rocks the view changed from millions to billions of years.

The origin of water on the earth remains to be a mystery. As the planet cools the surface of rocks burns out into carbon dioxide and together with water vapor formed thick cloudy atmosphere and toxic hostile water that remained for half billion years along yet with volcanic activity, formation of basaltic and granite rocks, ocean and continents. With radioactive dating, the scientists for the first time have tools to know the age of rocks, arrange them in systematic order and re-write the history of the evolution of the earth. With the slowly declining radioactivity and thereby removal of heat at the earth’s surface the first radical change towards a watery world took place and the formation of oceans.

Life was first appearing in the ocean and became free to move to land for 400 million years ago. For 200 million years swamps developed and later transformed to coal. Also, dead marine organisms transformed to oil and gas. These are the origin of fossil fuel, coal, oil and gas which probably required at least tens of million of years for formation and transformation. The first mass-destruction was the death of dinosaurs about 65 million years ago with appearance of mammals some 50 million years ago. Two million years ago modern humans appeared in the east coast of Africa and spread out of Africa where the ice age restricted the spread of humans further to Europe. As the last glacial retreated 10 thousand years ago, many new living conditions were further developed, e.g. with the creation of huge depressions making up many freshwater lakes and river systems in the northern hemi-sphere.

Lessons To Be Learned – The Total Collapse of Uganda After Independence.

Many countries in the developing countries, in particular Africa, were unfortunate by being left in a state of political chaos after their independence. The independence of Uganda in 1963 brought the country, with the help of the British officers, in the hands of Idi Amin, an uneducated illiterate commander. The U.K. was the first country to recognize Idi Amin’s regime after the shift of power from Milton Obote, Uganda’s socialist political leader. The U.K. Prime Minister Edward Heath, during the days of the cold war, welcomed the change from “communist government”. The people of Uganda though it is a new addition of social and political life as Idi Amin promised Uganda’s population to return to democracy after his overnight coup in 1971. Since that time Uganda sank in a very unpredictable history full of state corruption, nation-wide killing and mass execution by weapons, guns and airplanes brought from the U.K. to surprise Idi Amin’s enemies. Uganda’s middle class who built Uganda’s services, economy and businesses, i.e. the Asians and Indians previously brought by the British colonialism to build railways, were asked by Idi Amin to leave Uganda within one week. This was done in a move to further humiliate the British, to hand over the wealth of Asians and Indians, about 50 000 people, and to run the country affairs by Idi Amin’s supporters. This brought Uganda in enormous economic collapse as a result of destruction of Uganda’s infrastructure of services, entrepreneurs, commercial people, bankers, also the doctors were suddenly expelled out of the country. Those who started to run the country didn’t know how to run it with severe shortage of services. The collapse of Uganda’s services and economy followed a chain of public executions by Idi Amin of the critics and opposition of regime and further state corruption through black-market trade with coffee and alcohol.

Institutional and Management Responsibilities of Transboundary Water Systems

Trans-boundary water systems are hot issues as pressures on water resources are enormous especially shared trans-boundary systems. Utilization of surface water and groundwater resources differs in many aspects; also the negative impacts resulted from using these two water resources may differ. While surface water, e.g. rivers and lakes, are renewable, some groundwater are known to be of fossil origin, i.e. not renewable. In general, the rest of all water resources have specific residence times depending on the nature, structure and composition of their drainage areas as well as the hydrology of the systems. Rivers have the shortest residence times, typically few days, while lakes can vary from days or months for small ones up to several decades for large lakes. Sallow gravel aquifers may have residence times of few days, while deep aquifers may have very long residence times of some millions of years. Residence time of water, and particles therein, is simply the average time that a water/particle spend in a given system. Residence times of water have many important engineering applications in particular time-space hydrological, hydro-chemical processes, e.g. water budget, water balance and flow-rates as well as contamination and pollution studies. Also, in other water engineering disciplines such as biological, biochemical, biogeochemical, environmental and geological engineering as well sd rehabilitation actions.

For the Nubian Sandstone Aquifer System (NSAS), shared by Chad, Egypt, Libya & Sudan, which is one of the largest aquifer systems in the world, an agreement were conducted during the 1989-1999 “Constitution of the Joint Authority for the Study and Development of the Nubian Sandstone Aquifer Waters”. This agreement is more an institutional agreement than merely a water management one. However, the outcome of two projects that were conducted following this agreement, 1998-2006, identified key transboundary concerns what regards declining water levels, damage or loss of ecosystems and biodiversity, and deterioration of water quality. Based on these studies common management actions with adopted vision for the NSAS were concluded.

Adoption of Regional Strategic Action Plan on the Nubian Sandstone Aquifer

Yacouba Sawadogo – The Man Who Stopped the Desert

An African farmer, who out of nothing, created a whole bio-diversity in a dry desert. An innovation “Yacouba’s Zai-techniques” that proved effective for fighting against desertification. The word Zai comes from the original word Zaigre which means to left up the land and dig holes, a simple approach that can very well compete with high-tech solutions. Yacouba’s innovation, also, a revolution that can be used for mitigation of climate change by bringing people together in friendly mobile workshops to turn the desert, and stony land, to cultivated land where farmers can invest in trees, improve there food security and also help people to adapt to climate change. These are emerging new possibilities for young people.

However, illiteracy is major obstacle in developing countries that brings with it new threats for any new idea thus are endangering what has been achieved so far. Whenever threats appear wise people without power always appeal to intellectuals and authorities rather that verbal violence that doesn’t benefit anybody rather than damage and losses for everybody including authorities.

Where Knowledge and Literacy Rule, Unemployment and Hunger Cannot Prevail.

The keywords in all outstanding civilizations and democracies are knowledge and literacy. These are magic keywords for mitigating the risks for further increase in unemployment and hunger as natural consequences of the expansion of population, accelerating pressures on natural resources and the associated increase in consumption, waste and pollution. In no other era of human history, knowledge and literacy are becoming more and more inevitable, and even imperative, as instruments for any socio-economic developments. In particular, what regards sustainable management and use of natural resources by being our capital and reserve for a sustainable life. With the evolution of science and technology and the associated enormous transformation to knowledge-based societies, the only solution for erasing poverty is education in sustainable forms. It is education and research that have to be adapted to the society and not the contrary. Knowledge, through education and research, is an instrument and not a goal in itself. Throughout history, from ancient Egypt to modern civilizations, humans demonstrated how to use knowledge to turn the impossible to possible, i.e. through home-made inventions appropriate for there environments, people and for trade with other societies and cultures as well. In situations where humans were not always successful to manage conflicts, science and technology were/are being used for mass-destruction, control and abuse of natural resources.  Even without traditional schools, universities and research institutes, by our current standards and detailed management systems, ancient Egyptians succeeded to engage people to run and manage one of the very top civilizations in human history. What were possible thousands of years ago is still possible the only difference is how to shape knowledge to solve our needs, no more no less.

Food-Energy-Water Nexus

Feed-Food-Fibre-Fuel from agriculture, forest and farming are all dependent on landuse and water resources. However in arid and semi-arid areas, unlike temperate regions, water scarcity can be a major problem and energy are frequently required to use underground water for agriculture and farming. In all cases, i.e. even when water is available, waste from agriculture, farming and associated household applications can result in degradation of water quality. Energy is, always, required for treating used water and because of this “food-energy-water” are usually treated as essential policy-components for achieving sustainable socio-economic developments in many countries around the world and whenever necessary. This requires long-term and large-scale coordination of inter-disciplinary and inter-sectorial solutions with involvement of all stakeholders both on vertical and horizontal levels. These policies and solutions require appropriate public awareness, capacity building and skilled expertise with the suitable monitoring and management infra-structures and assessment instruments. These combined actions will have long-term positive feedback on economy, affordability and accessibility of food. An example on the interplay between food, energy and water is given below.
