Question

How is land
Being degraded? Suggest methods to conserve land resources?

Answer 1

Soil conservation is the prevention of soil loss from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.

Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. A sequel to the deforestation is typically large scale erosion, loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants, especially trees die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service. Farmers have practiced soil conservation for millennia. In Europe, policies such as the Common Agricultural Policy are targeting the application of best management practices such as reduced tillage, winter cover crops,[1] plant residues and grass margins in order to better address the soil conservation.Political and economic action is further required to solve the erosion problem. A simple governance hurdle concerns how we name and value the land and what we call it and this can be changed by cultural adaptation.[2]

Answer 2

Answer:

The ever growing demand of people for land to build up commercial areas, housing complexes in urban areas and expand the agricultural land in rural areas, reflect the changes in land use as well as in our society. These changes are responsible for the major threats like land degradation.

Some methods to conserve land resource are :-

1. Afforestation: One of the best ways to conserve soil is to increase the area under forests.

2. Checking Overgrazing: Grazing is very important.

3. Constructing Dams: One of the scientific methods to check soil erosion.

4. Changing Agricultural Practices
