problem in Mumbai‚ India According to G.Tyler(1994)‚ the more poor people move from rural to urban area the more poverty is becoming urbanized. A lot of cities have damage because of the extreme poverty and social and environment in stead of being centers of commerce and industry. In this article I will discuss the problem of slum clearance in Mumbai‚ India. I am interested in poor people in urban area. First I will refer about population growth which is related to urban problem. Second‚ I suggest

a bit of time to come to grips with this problem. Water pollution also occurs when rain water runoff from urban and industrial areas and from agricultural land and mining operations makes its way back to receiving waters (river‚ lake or ocean) and into the ground. STORMWATER Stormwater is a point source that contributes to water pollution. Because impervious surfaces (parking lots‚ roads‚ buildings‚ compacted soil) do not allow rain to infiltrate into the ground‚ more runoff is generated than

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

Cocker mouth is situated in the Lake District in England. England is an MEDC and this area experienced vast ranges of flooding during late November. The town lies among the confluence of two rivers that leave it prone to flooding. The two rivers are the Derwent and Cocker. 320mm of rainfall fell in under 24 hours and this was a predicted

In some cases‚ additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Besides creating environmental damage‚ the contamination resulting from leakage of chemicals also affect the health of the local population.[2] Mining companies in some countries are required to follow environmental and rehabilitation codes‚ ensuring the area mined is returned to

increases surface runoff since there is less oppurtunity for rainwater to sink into the ground. .Retarded or supressed infiltration accelerates overland flow production‚hastening delivery of rainwater into streams and rivers‚ the oftentimes the water ends up as floodwater into the ocean‚ especially for an archipelagic country like the Philippines. Forest denudation also deprives recharge of groundwater aquifers since there is less oppurtunity for water to linger in the ground surface to infiltrate

The Importance of Rewriting Storm Water Regulations Danielle Nielsen Goochland High School Abstract This paper observes the negative and harmful effects of water pollution and storm water runoff on the environment and the surrounding community. The most common form of water pollution is sediment runoff. It then goes on to explain the research and effectiveness of Best Management Practices (BMPs) and their positive effects. BMPs are conservation practices that can preserve or improve
