Abstract: One of the urgent problems Turkmenistan is development desert territories, which occupies 80%. The task scientific research to analyze energy supply and water for desertification this territory. priority use renewable sources, supply, groundwater. article considers eco-energy resources potentials solar lifting from depths, using technical economic methods evaluate capital investments,...

Desertification is one of the phenomena that threatening environmental, economic, and social systems. This study aims to evaluate monitor desertification in central parts Iraq between Tigris Euphrates rivers through use remote sensing techniques geographic information The Normalized difference vegetation index NDVI crust CI were used, which applied two Landsat ETM + OLI satellite imagery during...

soil is one of the most important natural resources covering a large area of the land surface. soil plays a vital role in biosphere processes, such as energy balance, hydrology, biochemistry, and biological productivity. it supports plants that supply foods, fibers, drugs, and some other human needs. conversely, desert regions include about one third of earth lands and these regions have increa...

several models have been developed to estimate land degradation rate and evaluate desertification severity. this study attempts to apply the medalus (mediterranean desertification and land use) model by considering existing conditions in the hamoun wetland, located in south-eastern iran. at first identification of the main factors affecting the desertification phenomenon was attempted, based on...

Desertification is a major environmental problem facing the world today, and climate change an important factor influencing desertification. This study investigates impact of changes in key factors on desertification based normalized difference vegetation index data, precipitation data evaporation from Inner Mongolia between 1982 2020 using correlation analysis, regression modelling, residual a...

a r t i c l e i n f o Land degradation in drylands is one of the major environmental issues of the 21st century particularly due to its impact on world food security and environmental quality. Climate change, shifts in vegetation composition, accelerated soil erosion processes, and disturbances have rendered these landscapes susceptible to rapid degradation that has important feedbacks on regio...

desertification is one of the major issues threatening human communities. manymethods have been developed for assessment and mapping of desertification hazards. in thisresearch, multi-criteria evaluation method was used to investigate desertification process introuti watershed, golestan province, iran. at the first step, major desertification factors weredetermined by doing field surveys. they ...

This paper investigates the hydrological interactions in the atmosphere-evegetation-soil system by using the bucket model and several new simplified intermediately complex models. The results of mathematical analysis and numerical simulations show that these models, despite their simplicity, can very clearly reveal the essential features of the rather complex hydrological system of atmosphere-e...

BACKGROUND Biological soil crusts are common components of desert ecosystem; they cover ground surface and interact with topsoil that contribute to desertification control and degraded land restoration in arid and semiarid regions. METHODOLOGY/PRINCIPAL FINDINGS To distinguish the changes in topsoil affected by biological soil crusts, we compared topsoil properties across three types of succe...

The United Nations Convention to Combat Desertification and its sister conventions, the United Nations Framework Convention on Climate Change and the Convention on Biological Diversity, all aim to halt or mitigate the deterioration of the ecological processes on which life depends. Sustainable land management (SLM) is fundamental to achieving the goals of all three Conventions. Changes in land ...
