Rapid population growth, urbanization and socioeconomic development are exacerbating the growing water demand (Bakir, 2001). Furthermore, pollution of water sources, uneven distribution of water resources and global weather change are exerting severe effect on water demand (Asano and Cotruvo, 2004) Therefore, to sustain the water crises many treatments technologies and purification techniques are adopted to meet required guidelines (Kennedy, 2010). Advanced water treatment technologies have ...
Air pollution is the human introduction of particulate matters, chemicals or biological materials into the atmosphere which can cause harm or discomfort to humans, living organisms and the environment (Energy Environment, 2009). The United Kingdom (UK) suffered its worst air pollution event when the Great Smog of 1952 formed over London. Within 6 days, more than 4000 people died and 100000 more were made ill due to the Smog's effects on the human respiratory tract (Fleming and Knorr, 1999; AEA...
In Southern Africa the most limiting factor to agricultural productivity is soil fertility. Soil fertility is defined as the condition of a soil that enables it to provide nutrients in adequate amounts and in proper balance for the growth of specified plants when other growth factors, such as light, water, temperature, and physical condition of soil, are favorable (van der Watt and van Rooyen, 1995). This phenomenon coupled with shortages of rainfall could results in a compounded problem of...
Since the industrial revolution, energy consumption by human populations has been raised at a rapid rate (McFarland, Hunt and Campbell, 1994). The growing use of energy by human societies, though, has a number of negative environmental consequences. Particularly, the extraction and combustion of fossil fuels (a process that is used to generate around 90% of the world's electricity) results in various environmental problems at local, regional and global scales (Holdren, 1987). The Educational...
This chapter presents the conclusions of the thesis. It provides a discussion of the implication of policy including legislative instrument, conservation policy, the outstanding universal value of OCG and stakeholders in conservation of residential heritage buildings. In addition, the chapter also provides recommendations for future research.Discussion of the Findings and ObjectivesThe main objective of this research is to determine the structural integrity of the residential heritage buildings...
If greenhouse gas emissions were to be stopped instantly, rise in temperatures and sea temperatures will still be experienced for various decades due to inertia in the climate system. Thus Climate Change is inevitable. Climate is changing as a result of human activity. This is suggested by scientific evidence. 'Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and...
Sagar Island, situated in the east coast of India and one of the biggest deltaic Islands in Sundarban group. This Island is unique with its natural ecosystem and has a potential for becoming a prime eco-tourism destination. The natural and man-made problems affect the quality of environment and life of people in Sagar Island. This paper examines the severe coastal issues of Sagar Island that include coastal erosion, threat to biodiversity, natural hazards, tourism and livelihood insecurity of...
Environment laws are must to make a healthy, wealthy and wise being. In order to have mental fitness, environment around a being must be well. Government of different countries has made different laws for protecting environment. Various laws were made in order to make the environment pollution-free like for air pollution, remedies were made such as gases liberated from the industry must not go beyond certain level. Similarly, wildlife protection, plantation were introduced in it. Certain...
Water is the most abundant substance on the face of the earth, and animals and plants likewise need it to sustain life. Outweighing land on Earth three-to-one, it has the potential to be more destructive than it can bring life. When most people think about the destruction that water can bring they think about hurricanes, floods, and droughts. Compared to acid rain, it is arguable that these are minor problems, considering that they do not occur very often. In discussing acid rain, it is...
Overview of climate change: Anthropogenic pollution of our environment, whether via deposits to our terrestrial environment, emissions to our atmosphere or discharges to marine and riverine systems are increasing, and we are now beginning to perceive the dramatic and permanent effects on a global level. The scientific community appears to have reached a general consensus with regards to at least one of these global environmental issues, climate change. [] The continued burning of...
