The imperative problem in these countries is lack of resources. This problem produces several others problems which directly or indirectly effect environment of these countries. In addition to this Cambodia has to face natural calamities like flood, drought etc each year. These again contribute in enhancing environmental problems in this country. (Dos, 2005)
Cambodia is a small country with many rivers. Major rivers of Cambodia either drain into Tonle Sap or into the Mekong River. The Cardamom Mountains & the Elephant range divide the region into three zones. In the eastern zone rivers flow into Tonle Sap. In the western zone rivers pour into Gulf of Thailand. While the rivers of southern zone flow towards south on the eastern side of the divide.
Tonle Sap gets seasonal flow of water. In months of September & October due to monsoon rains ,the flow in Mekong river increases enormously .Thus water overflows and inundates the delta. Flowing north ward this water empties into Tonle Sap. As a result the lake overflows, there by increasing its size from about 2,590 sq km to about 24,605 sq km.
These recurring floods are not only big blows to the economy of the Cambodia but also cause devastating effects on the environment of the effected places. After flood decaying plants and animal bodies carried with flood water are remains scattered throughout the places. Due to which the atmosphere of those places get polluted. Decaying substances get dissolved in ground water as well as in fresh water of water bodies. This cause post flood famines in this country.
After flood when the water level of Tonle Sap retreats a new layer of sediment gets deposited. Due to annual flooding and poor drainage the surrounding area of the lake gets transformed into marsh lands. During dry seasons these marsh lands are unusable for agriculture .Comparatively lesser amount of silt is carried away from the lake by Tonle Sap River than deposited by Mekong River. Thus gradually silting the lake and decreasing its water level and causing scarcity of water in dry seasons.
Cambodia suffers from occasional droughts. These droughts cause soil erosion and reduce soil fertility, which declines agricultural yield in favorable season. Cambodia being an agricultural country, to cope up with this problem increasing yield substantially was necessary. To fulfill this purpose use of fertilizers and pesticides are increasing day by day. Pesticides can be divided into three subgroups namely Insecticides, Fungicides & Herbicides. Insecticides comprise of Chlorine, Phosphorous, Carbonate chemicals such as DDT, Aldrin etc. Herbicides are generally used for controlling growth of weeds. These cause less harm to the environment than insecticides. Example of Herbicides are Atrazine , Propachlor etc. Herbicides do not leave long term effect on soil. Fungicides are mostly used in vegetable farms and orchards. The factors such as soil type , depth of water table , rain fall infiltration and persistence
Cambodia is a small country situated on Indo-China peninsula in South East Asia. It is bordered by the countries of Thailand, Laos & Vietnam on three sides and South China Sea on one side. This country has a very interesting history of naming. Before May 1989 it was called People's Republic Of Kampuchea…
The Dalit communities in India are groups who belong to one of the castes of the untouchables. These groups have suffered under oppression for centuries, the traditions of the social structure keeping them in poverty and despair, struggling for scraps of food and limiting their ability to earn a living to working in the ‘unclean’ professions.
The usual methods of disposal have become insufficient in controlling the growing waste production. Land filling and burning are the most accepted actions on solid waste management, however both could negatively impact nature due to the harmful leaks and gases generated from such procedures.
Municipal solid waste (MSW) consists of many different things including food and garden waste, paper and cardboard, glass, metals, plastics and textiles. These are also generated by commercial and industrial organizations although large volumes of chemical and mineral waste are produced in addition, depending on the sector.
Solid Waste Analysis When one considers the role that waste plays within the current economic system as compared to what it did but a few decades previously, there has inarguably been a paradigm shift. As a function of this level of understanding, this brief essay will seek to engage the reader with the ways that changing technology has fundamentally shifted the ways that waste is viewed and utilized.
The solid waste is recycled in such a way that it does not harm the society and the environment. More than 430,000 residential units and other organizations are getting the service of garbage collection by the department. The garbage collection for households is done on a weekly basis. Monthly schedules are followed to collect heavy trashes.
The author asserts that there are several methods that can be applied in the collection of solid waste. One of the methods used in the collection of solid waste is curbside collection, which entails the placing of closed containers on the roadside. Solid waste is put inside the containers; upon emptying.
o other acts that may be seen as acts of disposal of waste like the acts of littering in the areas that are unwarranted for such an activity (Stuart and Steiner 96). The other such activities include the ones of dumping waste in unauthorized areas and burning them. There are
The chapter shows many changes regarding the ways of managing solid wastes between 1990 and 2006. Typically, there are various methods of disposing solid waste material (Lanier & Eldredge, 2005). These include landfills especially
