Soil conservation is the prevention of loss of the top most layer of the soil 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.

Metrics details.

Soils are the fundamental resources enabling land to provide a wide array of benefits. Humans and wildlife alike rely on soils for the production of life-sustaining nourishment and shelter. Soil is important to society because it supports plants that supply food, fibers, life-saving drugs and other essentials and because it filters water and recycles wastes. Forested watersheds provide water purification, mitigation of floods and droughts, soil retention, and habitat maintenance. The quality and abundance of fresh water in lakes, wetlands, streams, and rivers determine aquatic and terrestrial species biodiversity.

Soil and Water Conservation Measures for Agricultural Sustainability

Limited natural resources are available on the planet under immense pressure due to the ever-increasing population and changing climate. Soil and water are fundamental natural resources for the agricultural production system. Anthropogenic and adverse natural activities are the major factors for the deterioration of natural resources. Among the various degradation processes, soil erosion is one of the serious threats for the deterioration of soil and water resources. In India, about Intensive agricultural practices accelerate the soil erosion process.
