land reclamation.
-The process by which seriously disturbed land surfaces are stabilized against the hazards of wind and water erosion. Surface mining for coal is responsible for almost one-half of the total land area disturbed in the United States. The drastic disturbance of the overburden severely changes the chemical and physical properties of the resulting spoils. These altered properties often create a hostile environment for seed germination and subsequent plant growth. Unless vegetative cover is established almost immediately, the denuded areas are subject to both wind and water erosion that pollute surrounding streams with sediment.

RELECTIONS
Singapore is in great need of land for housing. Being a globalised country, it had found ways to curb the problem, by land reclaimation. This is done to broaden the coastline and to get rid of swamps. Land reclaimation is practised to allow countries with land constraint. It has a positive impact as is provides countries with more land. However, land reclaimation is expensive and can only be practised in developed countries. Also, people living as reclaimed land will experience a greater shock during natural water occuring disasters.

More land has been made available for:
-building more homes in private and public housing estates and recreational facilities for the growing population
-expanding commercial and industrial activities and transport needs, including roads, expressways, the Mass Rapid Transit System, the port and airport facilities.
By 1990, the total land area of Singapore was 633 square kilometers. This was an increase of 51.5 square kilometers, which made up 8.9% the total land area. With continuing land reclamation, Singapore's land area will increase by about another 100 square kilometers by the year 2030. There are, however, constraints as to how much more land the country can reclaim. Two limiting factors have to be considered.
-Land reclamation works in the past used to be carried out from depths of 5-10m. Today, reclamation works have to venture into depper waters of 15m or so and this will incur much higher costs.
-It is also not so viable to pursue pushing reclamation further offshore because there is the competing need to maintiain the sealanes and provide new and larger ports for the bigger ships to anchor in Singapore's limited sea space.
