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.

Follow the stories of water resources around the globe.

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.

The so-called renewable energy sources/resources differ considerably and in many aspects from non-renewable ones. In “susutain-earth.com” we examined one type of electricity generation TPP “Thermal Power Plants” through using fossil-fuel “coal”. The “life-cycle”, in this case the transformation of fossil energy to electricity, was given including the production of waste and pollution as unwanted bi-products with environmentally damaging effects. We demonstrated, also, the so-called WE-nexus, i.e. how the production of (energy) electricity is dependent on water. Here we illustrate the “life-cycle” for production of electricity from wind.

The construction, installation and operation of wind turbines are simple in relations to the more complicated “TPP units”. With appropriate storage solutions, i.e. to compensate for variable power production “weather conditions”, they provide cost-effective and environment friendly solutions, as is the case for solar planels, i.e. with “zero” pollution and no need for water in operation.

Many of us have seen many power stations and industries are built near water bodies, this is because they need the water in their production or need to get rid of their waste, or both. Here we can see how Water and Energy are connected to each other, both with positive or negative impacts. Here is an example of positive and negative impacts given only in a qualitative and descriptive way.

Understanding “Water-Energy Nexus” is a key issue in Applied Sustainability in terms of how transformation of energy, i.e. from fossil form to electricity, not only needs and consumes water but also creates environmental pollution. The emitted atmospheric pollutants and rest products, in this case, e.g. carbon dioxide (100%), sulphur oxide 8%, nitrogen oxide (data on extraction yield is not given), heavy metals such as Pb, Cu, Zn, Cd, ….. (information and data on removal are not given) and water vapor. These pollutants and rest products have negative impacts on the environment in terms of degradation in air, water and ecological qualities, e.g. acid rain that cause acidification of aquatic systems with negative impacts on lakes, rivers and marine coasts.

The life cycle of thermal power plants starts with coal mining, coal transport, coal pulverizing and coal burning (combustion of coal to produce heat and produce water vapor to run the turbines and generate electricity). As mineral coal has different levels of impurities and pollutants, such S, N, heavy metals and probably small amounts of radio-active elements, all these substances will turn to bi-production. The bi-products are not likely to be completely removed and some amounts will be released to the environment as is evident in many areas in China by the naked eye. The negative impacts of such pollution on air and water quality are very well documents in literature, however some countries have improved their production technologies and have strict protection rules what regards air, water and ecological qualities. Nevertheless, emissions of “green house” gases, causing “global warming”, is still a major global problem. The scape of water vapor from fossil-fuel based-power and industrial plants around the world introduces disturbances in natural water cycles and adds new uncertainties in modeling the water cycles. Water vapor is also a “green house”. At the same time, the emerging negative threats from “WE-nexus” on achieving socio-economic developments need further improvements and actions what regards WE-management policies.

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.

The environmental importance is gaining greater and greater attention for policy makers around the world. Many countries are struggling to provide drinking water with good quality for their population. However, the quality of drinking water is very much related to the environmental conditions. The most important indicator for clean environment is availability of clean drinking water for everyone, this is also very much related to availability of clean natural waters and thereby clean environments.

Many countries in Europe can offer everyone the best drinking water quality in the world; in this context tap water in Europe can very well compete with the quality of bottled water.

Toxic compounds, hazardous chemicals and aggressive gases are not only produced in laboratories with restrict protection laws and well planned ventilation systems. They are, unfortunately, allowed to be produced and emitted as well as to keep circulating in our living environments and in the atmosphere around us. Though most of our concern is focused on “green-house” gases and the “green-house” effect, air pollution and air quality are among important environmental issues because of their severe impacts on health.

Many capital cities around the world suffer from “smog”. “Smog” has different origin and composition. Heavy industries using oil, metals and natural gas in their production can be potential sources for smog formation. Domestic fireplaces with coal and wood can contribute to major parts of the smog formation in some cities; this can be also the case with high volume of road traffic, rubbish incineration and dust from the surrounding deserts. In some mega cities the number of cars has increased to tens of millions in the last 30 years. However, fossil fuels, in particular coal, powered plants can still be major sources causing the biggest problem. Apart from man-made pollution, natural processes, e.g. sandstorms in hot arid and semi-arid regions/deserts can contribute to smog forming. In combination with intense ultra-violet rays industrial and automobile emissions can be transformed into, as transported as, ozone.

But, according to the most recent figures from the World Health Organization (WHO), the megacity doesn’t even rank among the top 10 cities for smog. Most of the worst afflicted are smaller cities across the developing world.

Poor air quality causes a number of illnesses for city residents, like chronic respiratory problems and lung cancer. According to a study by the Max-Planck Institute in Mainz, some 15,000 people die every year in Dhaka due to air pollution. Researchers found the world’s highest concentration of sulfur dioxide there. Smog can contain high levels of toxic chemicals, e.g. hydrocarbons, heavy metals, fine particulates, S-/N-/C- compounds, ozone, …. and other hazardous compounds.

The Chinese capital, Beijing, isn’t the only big city suffering from smog. From Asia to the Middle East to the Americas, here’s a look at the 10 worst cities for bad air. Beijing, China; Ahwaz, Iran; Ulan Bator, Mongolia, Lahore, Pakistan, New Delhi, India; Riyadh, Saudi Arabia; Cairo, Egypt; Dhaka, Bangladesh; Moscow, Russia; Mexico City, Mexico

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.

The following are currently considered to be the top five most sustainable cities in the world:  VANCOUVER, CANADA; SAN FRANCISCO, U.S.; OSLO, NORWAY; CURITIBA, BRAZIL; and COPENHAGEN, DENMARK.

When it comes to implementing sustainable initiatives these cities are leading the globe in how that achieved and/or can achieve sustainable cities through using renewable energy and by cutting back on emissions. Among common sustainability characteristics of these cities (http://archive.rec.org/REC/Programs/SustainableCities/Characteristics.html) are:

leadership in using and developing renewables; green transport and traffic with low emissions; strict and green buildings with improved energy efficiency and ongoing LEED-certified green building projects); high marks for air quality and clean environment; waste management with efficient and high recycling rates; reserve high percent of land to green spaces, ongoing projects for efficient electric car traffic (Vancouver and San Francisco); protected forest, parks waterways, and agriculture land (e.g. Oslo, Curitiba); intelligent lighting adjusting intensity depending on traffic conditions and weather (Oslo); bio-methane from waste to power mass transit and heating; projects for cutting carbon emissions by 50 percent in coming decades with goals to be the world’s first carbon neutral capital by 2025 (Copenhagen); heating system powered by high percent renewable energy, mainly from biomass from residual waste with plans to reach 100 percent renewable sources for heating in most the cold regions in the world (Oslo); innovative program that allows people to exchange trash for transit tokens or fresh produce (Curitiba); projects to get 50 percent of the population on two wheels by 2015 by closing down some major roads to cars and developing an additional 43 miles of bike lanes and requiring all new developments to incorporate some level of vegetation into building designs (Copenhagen).

Security and safety of citizens are essential features of safe societies and although it seems like the world is becoming more crueler with increasing instabilities, The Global Peace Index indicates here the 20 most peaceful countries in the world. The Global Peace Index issued by IEP (Institute for Economics and Peace) since 2007 gives data of nations’ and regions’ peacefulness as based on external and internal measures.

Among the essential features of the countries given here are that they prefer to focus on economic matters, building strong economies and creating a stable investment climate, trusted platforms for wealth management services and estate planning, instead of involving themselves in various armed conflicts. Many of these countries show great standards of living, have high levels of human development and place peace at the forefront of their priorities, e.g. they concentrate on being great neighbors, through establishing social, peaceful, economic, cordial political relations with other countries. Many of these countries work with the United Nations and its supporting agencies on a great variety of efforts, e.g. peacekeeping missions, and participate in various global, unilateral and multilateral organizations to promote international cooperation. They enjoy especially low rates of homicide, violent crime, criminality, organized internal conflicts, violent protests, internal and external wars fought, also, staying out of the main conflicts in the world. Sweden, for example, has a low level of robberies (only 9,000 a year) compared to the United States (about 350,000 a year)! Besides, Sweden has not been to war and has not participated in any combats for the whole 2 centuries. Many of these countries also enjoy political stabilities, neutrality in regional, international and global political issues while maintaining strong diplomatic relations with various countries around the world. Education in some of these countries is at the heart of literally everything, e,g. Finland’s education system is ranked fifth best in the world.

Many of these countries have unique culture diversity, fantastic travel destination, beautiful town halls, majestic castles, captivating and breathtaking natural beauty, alpine glaciers, golden plains and impressive mountains, spectacular coastline, sandy beaches and legendary hospitality, rugged landscape, wonderful fauna, awesome beaches and fantastic geothermal and volcanic activity. Many of them have vibrant, clean and safe cities with millennial heritage, spectacular scenery and friendly people.

Coordinated data on weather disasters and the associated impacts on population are becoming increasingly important, as the collective damage can be enormous. Abnormal weather conditions started to be more frequent probably becuase of global warming. Just during the first part of May 2014 a series of abnormal weather conditions took place in many parts in Africa and the MENA regions, below are some examples. These abnormal events of weather conditions are very rare to take place in these regions on times scales of at least several decades. These abnormal weather conditions that hit many countries in the same time-period can be an indication of large-scale phenomena/effects, but what???

6 May 2014, Burundi. Flooding kills 50 after torrential rains and storms that triggered mudslides, landslides and swept away homes, cut off roads and power, injured people, destroyed schools, houses, goods and public infrastructures. Houses in the poorer parts are often made of mud bricks and can’t resist against water and mudslides and landslides.

2 May 2014, Afghanistan. Landslide kills at least 350 because of heavy torrential rains (https://www.youtube.com/watch?v=Mj6Z_0Ty0BI&feature=youtu.be)

8 May 2014, Saudi Arabia. Flooding in Makkah (https://www.youtube.com/watch?v=x1vxRwFRjIE)

5 May 2014, Nigeria. 50 houses in Abuja were affected by flood (http://www.talkofnaija.com/local/flood-hits-over-50-houses-in-abuja-two-days-before-african-davos)

7 May 2014, Egypt. Massive sandstorm cloud rolls over Aswan governorate; heavy rain and flooding in the Red Sea governorate; 8 May 2014 heavy rain over 15 May bridge, Cairo (http://english.ahram.org.eg/UI/Front/MultimediaInner.aspx?NewsContentID=100838&newsportalname=Multimedia)

May 09 2014, Egypt. Flooding because of rainstorms caused panic for tourists (http://www.jerusalemonline.com/news/middle-east/israel-and-the-middle-east/israeli-tourists-stranded-in-egypt-by-floods-can-cross-the-border-5221)

In production strategies, more energy means more work gets done, it can also mean more conservation in energy can generate more work. The difference between these strategies is not only saving energy to get the same amount of work but it is the enormous saving of assocaited waste and pollution which in turn means more quality life, water for healthy food and conservation of environment. This makes the essence of modern sustainability, three-fold saving “energy-water-food” with enormous feedback on health, life quality and biodiversity. In this context, a  strategic question in the use of energy for production and living is: how much is enough in energy use and consumption? Can we humans use and consume as much energy as we wish and what are the limits? Are there any roofs for our energy needs for consumption, in this case what are these roofs, how they can be defined, monitored and implemented?

Indeed, global water scarcity started to be more pronounced is not because water on our planet is becoming less but it is because our energy needs for consumption are becoming not only unrealistically high but they are currently unaffordable and even inaccessible for future generations.

Since late 1040’s, water resource management in the MENA region (Middle East and North Africa including Algeria, Bahrain, Egypt, the United Arab Emirates, Iran, Iraq, Israel, Yemen, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Saudi Arabia, Syria, Tunisia, Qatar, the occupied Palestinian territories and Western Sahara “former Spanish Sahara”) faced several negative impacts as a result of asymmetric power relations, volatile political situations, political instabilities with periodic/continuous conflicts and wars. Under such conditions water policies were mainly focused on national short-term interests for securing supply and services with little, or even no, consideration to entire water cycle, e.g. the large-scale and long-term trans-boundary nature of the water resources in regions with shared rivers and/or shared groundwater resources. Furthermore, periodic conflicts and wars hindered developing appropriate economic-political instruments for efficient water-use and flexibility to manage long-term and large-scale supply and demand. Also, Integrated Water Resource Management “IWRM” for trans-boundary waters were lacking coherent policies of equitable and reasonable use, i.e. by being based on such factors as social and economic needs, size of population, access to other water sources, etc. The added-value to national and regional programs from several international donors involved in MENA water issues (the World Bank, UNDP and USAID) was therefore rather limited.

In addition to trans-boundary political conflicts, national governance is/was hampered by a lack of coherent laws, seemingly incompatible political interests, weak environmental legislation for over-exploitation of groundwater and over-consumption of water for irrigation with associated pollution and in-economic use of water. Pesticides, herbicides, industrial pollution, agricultural and household waste resulted in serious impacts on water quality, in addition to saline intrusion of the aquifers near the seas.

Water in the MENA region is integrated into the wider economic policies of the countries of the region and therefore water issues have to be addressed to multi-sectorial audience to bring about a broad reform within the current political and economic climate.  Indeed, MENA is using more water than it receives each year and most of the countries in the MENA region cannot meet current water demands. The situation is likely to be worse and per capita water will fall by half already before 2050, with serious impacts for the region’s already stressed aquifers and natural hydrological systems.

In coming decades, economies and population structures will force enhanced demands for water supply and irrigation, in addition to new needs to address industrial and urban pollution. Future management of water resources will be further complicated as the major part of the region’s water flows across international borders and climate change will introduce complex shifts in rainfall patterns. If the MENA region will not be able to meet these combined challenges the socio-economic consequences could be enormous, e.g. erratic drinking water services, more expensive desalination for cities and there would be needs for emergency supplies during droughts. Unreliable water resources, depletion of aquifers, service outages will cause stress on expensive infrastructure, depress farmers’ incomes, intensify local/regional conflicts with short- and long-term effects on economic growth and poverty, social tensions within and between communities, and increasing pressure on public budgets.

Post 1960s water policies of securing supply and services require switch toward better water management with consideration to entire water cycle and not the separate components, also use of economic instruments for water efficiency and flexibility to manage variations supply and demand. Changes in planning should include integrating water quality and quantity and consider the entire water system, promotion of demand management, tariff reform for water supply, strengthening of government agencies and stronger enforcement of environmental regulations. Also, shift from low-value uses to higher-value needs. Equal involvement of all stakeholders in water management policies including stakeholders outside irrigation, water resource management, and water supply and sanitation, e.g. within agriculture, trade, energy, real estate, land, finance, and social protection.

Reforms for sustainable socio-economic water management should involve: political and technical policies; effective interactions with non-water decision makers; accountability of government agencies and water service to the public as well as transparency for good and bad performance.
