Land degradation and desertification has been ranked as a major environmental and social issue for the coming decades. Thus, the observation and early detection of degradation is a primary objective for a number of scientific and policy organisations, with remote sensing methods being a candidate choice for the development of monitoring systems. This paper reviews the statistical and ecological...

during past decades, increased wastewater production by human activities intensified the problem of wastewater usewithout causing undesirable impacts on the environment and human life. however, practice of wastewater use inirrigation crops and green spaces needs careful control because of the potential presence of unwanted constituents such asheavy metals and organic contaminants. this research...

Investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. In investigation of pedological criterion onland degradation in Quaternary rock units, first, a part of the Rude-Shoor watershed area was selected. After distinguishing target area, maps of slope class...

Desertification leads to decrease in the ecosystem C pool and attendant reduction in Soil Organic Carbon (SOC). Reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. Our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...

Desertification is a major human tragedy, affecting the daily lives of about 1 billion people. It is this aspect of desertification that deserves further consideration. As a humanitarian effort it is an opportunity, and an obligation, for the industrialized nations to transfer financial support and technical assistance to those countries worst affected by land degradation in all its forms. Dese...

Undoubtedly, land degradation linked to desertification causes a decrease in qualitative and quantitative features of natural resources. This research aimed to assess land desertification by local residents and their role in controlling desertification in Isfahan province, Iran in 2016. The criteria were soil climate, vegetation, erosion, and demography. The indicators of soil texture, stone fr...

Natural and anthropogenic causes jointly lead to land degradation eventually desertification, which occurs in arid, semiarid, dry subhumid areas. Furthermore, extended drought periods may cause soil exposure erosion, and, finally, desertification. Several climatic, geological, hydrological, physiographic, biological, as well human factors contribute This paper presents a methodological procedur...

Abstract Desertification is one of the fundamental problems that threaten many arid and semi-arid areas. The formulation of the United Nation Convention to Combat Desertification (UNCCD), adopted in Paris, 1994 and ratified in 1996, with the active participation of Egypt, gave emphasis on combating the major threats to sustainability of dry lands. Recently, different models were developed to fo...
