Soil quality decline is one of the main causes of land degradation and is considered to be responsible for 84% of the ever diminishing acreage. Year after year, huge acres of land lost due to soil erosion, contamination and pollution.

These include soil erosion (loss of soil to wind and water), intoxication and salinization (increase in salt concentration).
