Category: Environment & Climate

All sectors of modern society can have impacts from environment and climate changes. There are two “groups” of waste and pollution, those with general impacts on the environment and quality of life, and the other group with specific impacts on climate and weather through the so-called global warming. However, there can be some overlapping between these two groups and induced effects therein. Achieving sustainable socio-economic developments depends on keeping good records and information on how our environment and climate are changing in terms of space and time. Air, water and ecological qualities are very much related to the consumption pattern of our common natural resources on the earth, also how we deal with our waste from household, agriculture and industries. Furthermore, waste and pollution can exist in different forms (gas, liquid and solid), originate from various sources and follow different paths of dispersion, and ultimately have different fates. Upon dispersion in the atmosphere, hydrosphere, ecosphere and in aquatic systems, pollution continues to interact with the biotic and abiotic components of the environment. Such interactions introduce degradation in climate, weather and the environment. Greenhouse gases, primarily from fossil fuel burning, cause global warming. Other types of pollution, e.g. heavy metals, toxic chemicals, acidic gases, agricultural and industrial waste, cause degradation of life quality and other damaging effects on the environment, water and ecological systems. Because of the existing and emerging competition on natural resources, and the diverse consumption pattern by stakeholders and industries, there are constant needs for developing treaties, conventions, regulations and agreements on all levels and sectors to protect the climate and environment and to promote sustainable socio-economic developments.

China’s Energy Needs – The Water Resources Set The Roof for Energy Use.

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.

MENA – Impacts of Political Instabilities and Wars on Water Resources.

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.

The Water Crisis in the MENA Region – Making the Most of Scarcity.

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.

Renewables Changed Bitter AC-DC Rivals to Successful Marriage

Thomas Edison and his Direct Current “DC” technology lost the historical so-called “War of the Currents” to Alternating Current “AC” in the 1890s that was championed by the Edison rivals Nikola Tesla and George Westinghouse. The argument was AC was far more efficient at transmitting electricity over long distances.

Edison, inventor of light bulb and the world’s first DC power distribution system in 1882 was not totally wrong to insist on the needs for DC distribution grid. The technological advantages of AC over DC at that time dedicated the success and expansion of AC power distribution grids initially developed in 1886 by Westinghouse and Stanley with major inputs from Nikola Tesla. An AC power system allowed voltages to be “stepped up” by a transformer for distribution, thus reducing power losses, and then “stepped down” by a transformer for consumer use. The AC technology became gradually mature for large-scale grid up-scaling. However, the advances of DC power distribution for long-distance power transmission took a revival in 1954 when the Swedish company ASEA, predecessor of ABB, the Swiss maker of power and automation equipment, linked the island of Gotland to mainland Sweden with high-voltage DC lines.

However, by late 19th century science and technology was too blind to recognize the problems associated with the use of fossil fuel, e.g. coal, oil and gas, for production and distribution of electric power. During the 20th century it has been an accelerating pile-up of threats not only from fossil fuel consumption what regards the green-house impacts on climate, but also the associated impacts on water resources from fossil fuel production in form of enormous and irreversible environmental pollution and degradation of ecological and water qualities.  With birth of renewables, e.g. solar, wind, geothermal, hydropower and wave power, and the continuous advances in associated DC and smart technologies the advantages of DC distribution grids became once more apparent. They are economic for high-voltage and high-capacity runs over very long distances, they are better suited to handle the electricity produced by solar and wind farms, which starts out as direct current.

Follow the emerging needs for transformation to renewables and the implementation of more sustainable management policies.

China’s Renewable Challenges for Efficient and Optimized Grid

China’s need for energy to serve its citizens and industries will accelerate tenfold in the period 2000-2035, i.e. from 1TWh to 9.6 TWh. Until now the share of renewables in China’s energy mix is about 17% while the major part of its energy, about 80%, is provided through fossil coal.

China’s challenges are related to its relatively very young renewable programs, and that the regions of highest energy demands are not matching China’s geographic distribution of its renewable energy production. Another challenge for China is the integration of its regional grids to a more efficient and optimized grid especially with consideration to the additional emerging renewable energies and the associated needs for storage. With these challenges a clear energy saving policy is needed for integrating renewable energy into China’s system. This is not an overnight and easy task especially if sustainable policies have to be taken in consideration for the reduction of greenhouse gas emissions which will remain to be one of the most serious difficulties for China not only from climatic view point but also from environmental and air quality prospective.

Renewables – European Challenges While Moving Towards A Super Grid.

Creation of a single electricity market in Europe has been moving in a positive direction. But, it is still a long way to go, particularly what regards the connection and integration of national electricity markets, the physical interconnections between Member States, and the promotion and facilitation of cross-border market-balancing. The same is true for the coordination of investment in generation, transmission and storage capacity. EU targets in areas such as climate change and energy security are additional challenges for achieving a single European electricity market. Renewable need to contribute to security of supply just as fossil fuel operators need to contribute to climate protection

In a single European energy market, the increasing penetration of renewables must be accommodated in a sustainable matter and this would require special considerations from the Member States. With increasing weight of renewables, the overall stability of the grid will certainly be ruined. The market is facing new challenges with the facilitation of self-consumption and peer-to-peer energy exchanges within distribution networks. Apart from technical and regulatory issues, the answers in every country are likely to differ because of the differences in energy mix and societal models. In this context, true pan-European market solutions can be favored over additional and scattered regulatory measures, as suggested below.

Iran – The Untold and Complex Story of Iran’s Nuclear Ambitions

The story of Iran’s nuclear ambitions to have nuclear power started already in the 1970’s upon recommendation from Ford’s administration of the US. The US, France, Germany and the UK though that Iran can be a good client for the nuclear technology and the UK started collaborating with the Shah’s of Iran on his development of nuclear power. However, the situation changed after the revolution in Iran with withdrawal of the west from further collaboration with Iran what concerns the development of nuclear power.

Under pressure from finite fossil fuel reserves and scrutiny from the West, Iran’s nuclear program has had a difficult road. Here is the story of Iranian nuclear energy told from the other side.

“Iran has tried its best to have a pragmatic approach, not an ambitious approach”, claims the country’s ambassador to the IAEA, Ali Asghar Soltanieh. A climate of suspicion and hostility has historically smothered any meaningful discussion of Iran’s right to nuclear technologies. The West accuses Iran of creating a ‘confidence deficit’ by pursuing a clandestine programme of enrichment; Iran sense hypocrisy, and claim to be singled out.  Ultimately, all parties acknowledge that a system that enshrines the right of the powerful to bend the rules is unsustainable. “The whole of the non-proliferation regime has elements of double-standards built into it”, concedes David Hannay, a member of the House of Lords. But will this consensus signal a move beyond the rhetoric to purposeful negotiation? “Iran has an opportunity to become the good boy of the world.”

One central issue what concerns the globalization of high-tech industries, and other emerging sustainable technologies, is how would we achieve sustainable socio-economic development around the world that involve secure and safe use of clean energy and water resources. However, there are many important political challenges what regards raising public awareness, promotion of supporting education and research programs that can solve society and populations needs. In this context, stronger engagement of all sectors and stakeholders are required for the conservation and protection our natural resources.

Berlin/IPCC – Greenhouse Gas Emissions Are Still Accelerating

Berlin, 13 April – A new report by the Intergovernmental Panel for Climate Change “IPCC” indicates that global emissions of greenhouse gases have accelerated despite reduction efforts. The report, also, shows that many pathways to substantial emission reductions are available. As, many other atmospheric pollutants and toxic compounds are expected, also, to be associated with the emissions of greenhouse gases, then enhanced degradation in world aquatic and ecosystems will be taking place in parallel. In addition, the sites where these emissions are taking place there would be additional local and regional problems as well to the workers, in particular “high occupational levels of pollution” and the public health of individuals “air quality” in general.

South Africa’s Sustainability Challenge: Food; Energy and Water

By 2030 South Africa will have 60 million people, i.e. more than double of today’s population, to feed. Today’s water and energy resources are already used up for living and providing food. The only solution is SUSTAINABLE planning and recognizing the way these three resources, i.e. food, energy and water, are INTER-CONNECTED.  We need sustainability as much as sustainability needs us.

Canada Oil Sands – How Sustainable is Sustainable?

 

Increasing energy demands and pressures on Conventional Light Oil “CLO” of the Eastern Hemisphere (85% of the global inventory) have shifted the focus to Unconventional Heavy Oil “UHO” and Conventional Tar Sands “CTS” deposits around the world. The major part of “UHO” is in the Western Hemisphere (69% of the inventory), mainly the USA, while the majot part of “CTS” is being found in Canada. We have to keep in mind that the world inventories of UHO” and “CTS” may, indeed, exceed the global inventories of “CLO”.

Unconventional oil sources and oil sands are created in the same way as conventional oil—that is, through the combination of organic material, heat, and pressure. The main difference between the two is their ability to move underground. Conventional oil migrates upward due to its buoyancy. This oil moves through pathways in the underground rock in its fluid state and becomes trapped between impermeable layers of rock. Unconventional oil and oil (tar) sands, meanwhile, is formed in sealed spaces of rock, or being mixed with sand, and is not able to move up; it therefore remains in the source rock/sand, trapped in pores or unconnected pores. Unconventional oil and oil or tar sands are therefore produced and extracted using techniques other than conventional method used in Conventional Oil industries. Governments across the globe are investing in unconventional oil sources due to the increasing scarcity of conventional oil resources. 

Due to the different nature of accumulation and existence in underground formations and difficulties associated with production/extraction of unconventional oil and oil sands there are multiple of additional environmental threats and climatic impacts. Production and extraction of unconventional oil and oil sands consume much more water, have enhanced negative impacts on the environment in terms of produced waste, contamination and pollution especially what regards degradation of aquatic life, eco-systems and bio-diversity. Moreover, carbon dioxide emissions from the production and extraction of unconventional oil and oil sands are relatively higher, up to 20%. Indeed, the climatic and environmental (http://blogs.worldwatch.org/revolt/unconventional-oil-implications-for-the-environment-and-greenhouse-gas-emissions-2/) impacts of unconventional oil and oil sands are not fully understood and consequence assessment analyses are fragmentary, incomplete and far from being representative especially what regards the large-scale and long-term impacts and threats.

Uganda – Green Politics for Sustainable Socio-Economic Developments

Bringing about sustainable socio-economic developments in any society is an enormous task and requires mobilization of a wide-range of stakeholders in all sectors and on all levels.  Politics in this context is of central importance for turning sustainability to reality especially in developing countries.

Uganda recognized the importance of green politics in 2006 where Pilot International (http://www.pilot-int.org/index.html) was founded, by ROBINAH K. NANYUNJA (Full BIO: http://www.robinahknanyunja.com/robk/?page_id=38, the President General, Ecological Party and Uganda’s Green Party. The mission is to promote global sustainable development for the benefit of humanity and the planet, advocate peace, security, unity, preservation of the environment and ecosystem for socio-economic development. The Green ideology of Pilot International rests on solidarity that can be expressed in three parts: Solidarity with all the people of the world; Solidarity with animals, nature and the ecological system; Solidarity with future generations.

Transformation to Clean Energy – The Canadian Challenges

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.

Lessons to be learned – The Sustainability Program of North Ireland

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.

GREEN POLITICS ANSWER TO GLOBAL ENVIRONMENTAL CHALLENGES

The green ideology is a philosophy practiced and advocated for by a coalition of political leaders and activists, whose goal is to advocate for peace, security, unity, preservation of the environment and ecosystem for socio-economic development, all over the world. These political leaders and activists are called “The Greens”. The Green ideology rests on solidarity that can be expressed in three parts: Solidarity with all the people of the world; Solidarity with animals, nature and the ecological system; Solidarity with future generations. For more information on this Political Platform, please, visit:

Mechanized Agriculture in Sudan – Collapse of Sustainable Land-Water Management.

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.

Amazing High Tech Farm – A Complete Meal Using A Mobile!

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.

Do-It-Yourself: How Does Methane Biodigester Work?

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.
