Land conservation

In day to day life we see the environment. Since we born we have seen large changes in the environment. Forest are cut down for housing, farming, construction, recreational purposes and other land uses. Some of these needs are required to human life to survival. Therefore nowadays environmental related societies tender to land conservation strategies.

Land Conservation is the process of protecting natural land and returning development to its natural state. Conservation is important to prevent floods, fires, new desert and drought. It is useful to protect rainforests. By doing land conservation increase the vegetation.

There are some techniques to land conservation such as preservation, restoration, remediation and mitigation.

Preservation is maintained the land and should not be consumed by human. Human can access the land but only utilize its natural beauty and inspiration.

Restoration is returning ecosystem.

Remediation is the process of cleaning a contaminated area using relatively mild or nondestructive methods.

Mitigation is the process of replacing degraded site with a healthy site. A mitigation is creating a new area that is of equal ecological value. This technique allows land to be destroyed.

Land Conservation have two type,

Natural land conservation
Man-made land conservation

Advantages of land conservation

Increase the organic matter
Reduce machinery wear
Reduce labour, save time
Save fuel
Improves soil tilth
Traps soil moisture to improve water availability
Reduce the soil erosion
Improves water quality
Increase wildlife
Improves the air quality
Build soil structure and health

Natural land conservation

Grass Land

Installing Paving Materials

Forestation

In the university premises we can identify natural land covers example grassland, trees. In this also some land covers are developed by man. Example grass land made by man. The purpose of this land covers are basically to prevent from soil erosion and aesthetic appearance.

As well natural land covers provided better ecosystem to live and natural biodiversity. The above figures identify trees, grassland, bare ground, water etc. In the land covers the plants that have grown provided a strength to soil and tightness to soil.

Man- made land conservation

Total land cover is the surface of land in the country. Including artificial land, crop land, wood land, scrub land, grass land, bare land, water land and wet land. In the university premises in several locations artificial land covers are located. Example inter lock block used in food court entire area. These land covers use to soil conservation from flooding and other climate changes effects. This covers provided landscape design to the location. Below figures the location like tennis court, Baseball ground. Land covers are made to entertaining purposes. Basically these two categories of land covers conserve the soil and provide aesthetic appearance. Some time it will cost highly but there are biodiversity advantages.
