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.
Effects of erosion impacts two places. â¢ On-site Effects. â Loss of topsoil. â Water-holding capacity of the soil. â Pollutants carried off by water. â¢ Any chemicals present on a site move with the eroded sediment or water. â¢ Off-site Effects. â Soil detached by accelerated wind or water may be transported.
