Air pollution has become the world’s single biggest environmental health risk. According to WHO it is linked to around 7 million death or nearly one in eight death in 2012. The new figures are more double previous estimates and suggest that outdoor pollution from traffic fumes and coal-burning, and indoor pollution from wood and coal stoves, kill more people than smoking, road death and diabetes combines.
The document is WHO’s Air Quality Guidelines Global Update 2005. These Guidelines offer guidance to policy-makers on reducing the effects on health of air pollution for the four most common air pollutants – particulate matter, ozone, nitrogen dioxide and sulfur dioxide. Also, issues affecting the use of the guidelines in risk assessment and policy development.
This document contains Part (1) Application of air quality guidelines for policy development and risk reduction; Part (2) Risk assessment of selected pollutants (Particulate matter, Ozone, Nitrogen dioxide, Sulfur dioxide).
Air pollution is a worldwide problem especially in many big cities and industrial areas around the world. Emission of fine particulate matter (e.g. aerodynamic diameter ≤ 2.5 µm; PM2.5) , chemicals (e.g. biogenic VOC) and pollutants (e.g. heavy metals), and associated photo-chemical reactions (e.g. production of tropospheric ozone) in the atmosphere as well as in-cloud interactions (e.g. acid rain) experienced dramatic changes since the industrial revolutions. Concentrations of hazardous pollutants in global atmospheric air masses, dry and wet precipitates have been subject to gradual increasing reaching harmful levels for air-quality what regards human health (e.g. lung cancer, mortality) and the environment (e.g. negative impacts for forests and vegetation and quality of life in aquatic eco-systems) in many places around the world.
Climate change influences air quality through several mechanisms, including changes in photochemical reaction rates, biogenic emissions, deposition/re-suspension, and atmospheric circulation. Several techniques/approaches were used in such studies including atmospheric chemistry, climate model inter-comparison, high-resolution satellite observations together with a global atmospheric models and extensive compilation of surface measurements to better represent global air pollution exposure.

It is interesting and even generous that some nations and civilizations were able to maintain something that describe and illustrate the beautiful reality but yet a difficult and critical past of their history. It is part of the nations and civilization’s mindfulness of their cultural heritage where conflicting history is turned to friendship. Granada is a true window for a glamorous past worth visiting instead of reading history books. Granada is an integration of innovative architecture, cultural history in a unique social and environment context.

The world is experiencing tectonic changes in terms of population, economy, production, services and technology. The world in the year 2050 will not any longer be as it used to be in the past decades.
The world population will grow from 6 billions in the year 2000 (one billion in the developed world and five billions in the developing world) to 9 billions in the 2050. One hundred million out of the three billions of the global increase in population will go to the developed world, while the developing countries will increase by 2.9 billions. This is a dramatic shift in world population in the coming five decades only, i.e. an increase from 6 to 9 billions.
The other consequential change is, by the year 2000, the developed world (one billion people) had 80% of the global economy while the developing world (five billion) had the remaining 20%. But, by the year 2050, the developed world will have only 35% of the world economy, while the developing countries will have 65% of the global economy. So, the 80% vs 20% of global economy of the year 2000 will be change to 35% vs 65% by the year 2050. This is just turning the world on its head in terms of the world that used to be in the past decades. This dramatic change in the structure of world economy is being driven by the development in global population and the fast transfer of modern technology to the developing countries.
You can imagine how such monumental economic shifts mean to the young generation world over. This is a change of enormous importance where India and China by the year 2050 will constitute 50% of the global GPD, this is a monumental switch in terms of economical power.
In the year 2000, one billion middle class people were in the rich countries and half billion people were in the developing countries. By the year 2030, 2 billion middle class people will be in Asia (one billion in China by 2050). Africa will grow from 850 millions people in 2000 to two billions people 2050. By the year 2050, the average income in Africa will be 2000-3000 dollar per capita, for China and India will be between 30 000 and 40 000 dollar per capita, and for the countries in the rich world (US and Europe) will be between 90 000 and 100 000 dollar per capita.
Africa is a continent that is not any longer isolated, it is not a place where people are not well informed as information is passing and moving very quickly. Much trade and business in China and India is geared towards Africa.
These tectonic changes have monumental impacts on the young generation and they have to think very carefully how to face the global transfer in economy, production, services and technology. Education figures for the year 2007, tell us that 110 000 Chinese and over 100 000 Indians were studying in the US, while only 11200 Americans were studying in China and 2800 Americans in India. But, these figures will experience dramatic changes in the future because the mentioned major shifts in economy, production, services and technology.
The western countries were able to stay ahead because of (1) manufacture and that was taken away and moved to Asia; (2) service industries that first moved into the western countries but is moving out again to Asia by their gradual dominance in the service sectors; (3) technology where the west were able to stay ahead, but now the technological advance is being shifted as well to Asia. The challenge is now what is left for the west to do??
Necessity is the mother of invention. Where energy lacks there is much concern about finding it and using it with the most sustainable manner possible. This is why Iceland is among very few countries in the world where Renewable Energy Resources are managed with the best possible sustainable solutions. It is, also, possible that the availability and affordability of renewable energy in Iceland attracted Scandinavians to settle in Iceland sometime around the second half of the 9th century as in ancient cultures people sought living there were good possibilities to secure “WE-resources”. i.e. water and energy resources. The necessity and needs for survival are essential drivers for inventions and advances in science and technology. It is interesting to mention that 100% of the electricity production in Iceland is produced from renewable energy resources, i.e. hydropower and geothermal heat. Furthermore, 85% of total primary energy supply in Iceland is derived from domestically produced renewable energy sources.
So, we have something to learn from this country that in addition of being in the icy part of the world has a very long dark winter season. However, Iceland is not as cold as Minnesota (USA), for example, and not as dark as Tromso (Norway). That doesn’t mean that Island is some tropical paradise though.

The dream of any nation is to provide its population with safety and security especially in most critical situations with severe disasters, tragedies and collective nightmare arising from fear, insecurity and uncertain future. The nuclear disaster and the national tragedy from Fukushima nuclear accident in Japan demonstrated how collective efforts, the neat national planning along with continuous and intensive hard-work brought about safety and security for almost all the population in Japan.
An amazing awareness and responsibility on all levels for the DE-COMTAMINATION of every single inch or centimeter of land, houses, school, hospitals, roads, trees and practically all environmental compartments. A national DE-COMTAMINATION strategy if followed by other nations much of pollutions and waste problems can be solved. Successful sustainable management is about providing future generations with secure and safe living conditions, it is a collective discipline, awareness and responsibility from all for all and by all including preparing and fostering future generation for how to handle national disasters and severe tragedies.
Geothermal energy is among potential “semi-global” natural energy resources, as it is only accessible and affordable in economic terms in hot and limited areas around the globe. It is also considered to be relatively user friendly, more energy-intensive in comparison to solar energy, has less threats in case of technical failure as compared to nuclear power, simple and more safe production-technology in terms of drift and above all more durable and lasing natural source. It is indeed a form of “fossil resource” as being a remainder from the Big Bang. However, unlike energy produced in stars such as in the sun (solar energy) through fusion-reactions, energy in planets such as the earth is being produced through decay processes of the primordial radio-activity. Actually, without the embedded sources of heat in the earth’s body, i.e. the energy emitted through the decay of natural radio-activity, e.g. the radio-active members of the U and Th series, and many other radio-active isotopes of other elements that can have half-lives much longer than the age of the universe itself, e.g. Te-128 of half-life of 2.2 exa millions (billion billion millions) of years.
The most interesting issue in energy production and use is that water in always involved in these processes with two main impacts what concerns WE-resources, i.e. Water and Energy. For energy we are consuming more energy resources and thereby less we are gradually facing less access to energy resources and as a consequence increasing prices of energy production. As energy production, use and consumption create more waste and pollution as well as bring water to more open systems and interactions there is continuous and gradual degradation in water quality and thereby increasing threats to all life forms on the earth.
So, production and use of geothermal energy can be, also, associated with negative impacts on water resources, environment and bio-diversity.
An important aspect for appropriate implementation of Sustainable Technologies is Sustainable Management. The fundamental question is How Sustainable is Sustainable? And what are the most appropriate solutions for Achieving the Best Socio-economic Sustainability? Among strategic long-term and large-scale policies for the MENA region, where arid and semi-arid conditions prevail, is Water Management because of its impacts on all involved sectors (energy, industry, agriculture and environment) in this region, life quality and bio-diversity. Unfortunately, existing literature still lack appropriate long-term and large-scale sustainability solutions as being based on “Business as Usual” without consideration to other possible and yet feasible alternatives.
Seawater desalination constitutes an important source for water supply for all sector activities and the population in the bordering the Arabian Gulf, the Mediterranean Sea, and the Red Sea. Desalination has advantages and disadvantages that may depend on the region, location, technology, impact and amount of fresh water production. Apart from the energy requirements for desalination, there are also other negative impacts in terms of waste management, fish production and quality of marine life in general. However, these impacts can be mitigated or even eliminated, by solutions other than those currently available.
Increasing pressures on natural resources, in particular availability, accessibility and affordability of Water and Energy “WE”-resources, require Sustainable Management Policies that consider shaping and integrating Sustainable Technologies to meet the growing needs for large-scale and long-term transformation to New Sustainable Life-styles. Unlike, in ancient civilization where population settlements were created at/around fresh surface-water bodies, e.g. rivers, lakes and deltas, future settlements are likely to grow faster at coastal regions “Hydroponic Coastal Colonies” and non-traditional living areas with limited fresh-water resources. Agricultural production may not require land to the same extent as in traditional farm communities; modern technology will allow more Sustainable Cities to grow on coastal areas as well. However, climate change threats for increasing sea-water levels have to be taken in consideration, what we have learned from the past safety and protection measures are always part of any successful socio-economic developments. The future is bright by innovation and not by imitation.
Shaping and Integrating Modern Technologies for Sustainable Cities and Global Food needs
By Chemist/ Safwan Elfar, Qatar
The earth’s surface went through enormous large-scale and long-term shaping and re-shaping evolution history that resulted in todays earth’s “face”. In the last million years these shaping and re-shaping processes of the earth’s surface were continuously fueled by dominant erosion processes of natural origin that carved land-areas, holes and trajectories for coastal, surface and groundwater systems, e.g. rivers, lakes, coastal deltas and shores, fjords, water-falls, forests, natural parks, caves and other major geological formations. However, modern man-made interferences are becoming increasingly important, primarily because of increasing activities and processes on the earth’s surface in particular urbanization, mining and global warming. Recent climate changes, for example, are imposing extreme daily and seasonal variations in atmospheric temperature, gradual warming of oceans, seas and surface water systems with feedback impacts on atmospheric, oceanographic and hydrospheric erosion processes. These processes are brought about by the action of more dynamic air and water masses on different scales ranging from micro, local, regional and global scales, e.g. dynamic changes in speed and velocity of wind and water waves, also heating, freezing and de-freezing cycles “expansion and contraction” and geothermal processes.
Erosion is the main source of nutrients supporting the formation of vegetation cover, animal and evolution of bio-diversity and the very origin of natural agricultural production through photo-synthesis and associated biogeochemical, geophysical and geochemical machinery of the functioning and metabolism of global eco-systems. However, modern pollution and waste because of industry, agriculture and household have severe negative impacts of all life forms on the earth’s surface.
Asbestosis is known to affect the tissue of lungs as a consequence of the inhalation and retention of asbestos fibers. This usually occurs after high intensity and/or long-term exposure to asbestos from mining, manufacturing, handling, or removal of asbestos. This is, also, the case for people in houses or areas contaminated by asbestos. Sufferers may experience severe dyspnea (shortness of breath) and are at an increased risk for certain malignancies, including lung cancer but especially mesothelioma.
As the damage to lungs occur from contaminated air, early investigation were carried out through measurements of asbestos levela in air samples, which is suspected to have caused asbestos-related lung problems.

The rosy festival of continuous prosperity growth has recently been challenged by the theory of “Peak Oil”, which concludes that the amount fossil energy (oil, gas and coal) being extracted from the earth will shortly start an irreversible decline. We will be increasingly dependent on other energy sources to power our civilization, if not to say our long-term survival.
Assessment of the global energy resources, consumption and trends in global energy-mix with consideration to increasing global population shows that energy per capita will decrease. This will have negative impacts on GDP “Gross Domestic Product” and probable escalation in the costs of raw material, e.g. fertilizer and the diesel fuel or electricity for water pumps that are essential for agriculture and production of food. We will be, therefor, moving fast not only towards energy poverty but also towards global economic recession, pushing many countries and population towards increasing poverty, e.g. shortage of water, food and housing.
Efficient heating and cooling technologies with little or no carbon dioxide within residential, commercial and public buildings can dramatically reduce the world energy consumption and thereby considerable saving can be achieved. This can generate positive feedback effects on energy prices, global warming and life quality. This will promote more sustainable developments worldwide.
However, strong policy and awareness actions on all levels, sectors and stakeholders are needed to bring coherent solutions in the fragmented building sectors. In this context, increased technology RD&D is necessary to bring about new and affordable solutions that are suitable for different climate zones along with the environmental, cultural, social and economic conditions during the life-cycle financial benefits.

Knowledge on the World Energy Resources “WER” is much more important to know as compared to the World Water Resources “WWR”. In both cases management policies in terms of quantity and quality are IMPERATIVE.
While knowledge about Climate Change is essential for implementation of sustainable long-term and long-term management policies of the Water Resources, there are relatively more aspects to be considered for the sustainable management of the Energy Resources. Humans cannot manipulate “WWR” or Global Water Resources “GWR” in terms of quantity. What we get, we will get, and we can do nothing about it. However, regarding the quality of GWR it is the responsibility of humans to keep track on quality at all levels and on different scales, i.e. in terms of location and occasion “spatio-temporal scales”. So, what regards “GWR” management policies, technology is primarily coupled to consumption priorities of sectors, stakeholders and users as well as waste and pollution issues with consideration to climatic issues.
Management of “WER” involves production, consumption, and waste and pollution issues taking in consideration sectors, stakeholders and users. But “WER” require global players for import-export of both raw material and processed energy as well and in both cases waste and pollution aspects are involved. The dynamic balance of fossil versus renewable energy resources are very much technology related. Even in this case, Climate Change is becoming an important factor regulating how the dynamic balance of fossil versus renewable energy should look like, i.e. on “spatio-tempral” scales.
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 .

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.

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.
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.

The journey of science, to understand the very secret of the universe and the natural evolution of life, and the behavior of humans and the feedback impacts of technology on the fundamental drivers of life and its quality, never stops. A journey that fuels itself to complete Darwin’s “Unfinished Business”, and to search about a new vision of nature, a “Metanoia rather than Affluenza”. A journey directed by science and technology for sustainability and preservation of life, rather than for consumption and collapse of life, would help nature to resume rather than to relapse from the natural path of evolution.
