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.
Deforestation also has a profound effect on many of the worldâs water cycles. Reduced vegetation and ground-cover leads to a general drying-out of the soil â which over time leads to lower levels of rain. And, eventually, leads to significant soil erosion and desertification.
