Desertification involves many countries featuring different ecological, economic, and social conditions. In Mediterranean Europe, high human pressure, economic development, and climatic changes combine to produce land consumption, soil erosion, salinization, and fire risk, all considered as key factors to start desertification processes.

During the first 40 years of British colonial rule in Zimbabwe, from 1890 to 1930, European farmers and miners established commercial farms and mines (in prime natural regions

A study was conducted to estimate the rate of solid and dissolved mass denudation from six prominent landuse systems of Bhetagad micro watershed, Gomti basin of Indian Central Himalaya. An investigation was also conducted to assess the seasonal variation in water quality parameters influenced by rainwater in the four sub-catchments of Gomti basin.

A lot of wash load comes to the streams during the rainy season due to the erosion of soil from the catchment and known to flow practically without settling on the streambed. The presence of wash load is known to affect the resistance to the flow. The effect of its presence on transport of bed material load is not well known. The present paper is devoted to a review of the studies regarding concept of wash load, changes in resistance to flow due to the presence of wash load, the effect of presence of fines in suspension on the transport of bed-material.
