(e) crisis conditions in traditional agriculture with associated land abandonment and deterioration of soil and water conservation structures

Deforestation, soil erosion, deterioration of soil quality, depletion and salinization of water resources, pesticide poisoning, loss of biodiversity, pollution, climatic and biotope change are some of the major environmental effects of current agricultural practices.

The major land degradation problems in Egypt are related to hydrological constraints which cause waterlogging, salinity and alkalinity, physical constraints such as deterioration of the soil structure and compaction, and biological constraints caused by a decline in soil organic matter leading to declining soil fertility.

Soil

The Convention defines desertification as reduction or loss, in arid, semi arid and dry sub humid areas, of the biological or economic productivity resulting from deterioration of the properties of soil, from soil erosion, and from degradation and long term loss of natural vegetation.
