SILVICULTURE FOR SOIL CONSERVATION, WATER RESOURCES AND TO COMBAT DESERTIFICATION

Proposed policies for integrated watershed management in order to combat desertification in Euphrates and Tigris basin

Desertification of the arid and semi-arid lands of the world has been proceeding for more than a thousand years.Human-induced degradation in these areas is regularly cited as one of the principal causes of desertification.Euphrates and Tigris Basin as the case study of this research in some aspects is almost unique in the world. But thisbasin has been confronted to progressive desertification. ...

Land Degradation and Soil Conservation Desertification: Causes and Strategies to Compete

Conservation Laws for Equations Related to Soil Water Equations

where ψ is soil moisture pressure head, C(ψ) is specific water capacity, K(ψ) is unsaturated hydraulic conductivity, S(ψ) is a sink or source term, t is time, x is the horizontal axis, and z is the vertical axis which is considered positive downward. Equation (1.1) is an approximation within the context of the theory of mixtures. It is studied here in the form (1.1) as a first step. An introduc...

Submission by the United Nations Convention to Combat Desertification

The world's soils hold more organic carbon than that held by the atmosphere as CO2 and vegetation, yet the role of the soil in capturing and storing carbon dioxide is often one missing information layer in taking into consideration the importance of the land in mitigating climate change. Extraordinary demands are being placed on agricultural systems to produce food, fiber and energy and yet the...
