the derakhte senged area is located in south of neishaboor town at khorasan razavi province. in this research, desertification intensity of derakht senged area was evaluated using imdpa, one of the newest method to assess desertification potential in arid and semi arid regions of iran. to evaluate desertification intensity, based on the primary research in this area, 4 criteria were selected in...

Societies in semi-arid areas in developing regions are amongst those, most vulnerable to climate variability and potentially most vulnerable to climate change. The vulnerability to climate variability is caused by the strong restrictions that limited water availability poses on the use of natural resources, by the generally low reliability of water availability and, on the other hand, an often ...

Climate change has resulted in increased vulnerability of smallholder farmers in marginal areas of Zimbabwe where there is limited capacity to adapt to changing climate. One approach that has been used to adapt to changing climate is in-field water harvesting for improved crop yields in the semi- arid regions of Zimbabwe. This review analyses the history of soil and water conservation in Zimbab...

Retrieval of eco-hydrological variables/parameters from the orld’s cold and arid regions using remote sensing is more chalenging compared to other regions, and less research work on uantitative remote sensing has been carried out in these specific egions. This is because: (1) Cold and arid regions are most likely o be located in theworld’s remote and relatively under-developed reas, where conve...

‎Nosemosis is one of the most prevalent bee diseases in the world causing significant ‎economic losses in the global bee-keeping industry. This cross-sectional study was conducted during April-September, 2016 to investigate the prevalence of nosemosis in different climatic regions of Iran. A total of 183 ‎apiaries were selected based on cluster sampling and the climate of apiar...

Dry Land Asia is the largest arid and semi-arid region in the northern hemisphere that suffers from land desertification. Over the period 1982–2011, there were both overall improvement and regional degeneration in the vegetation NDVI. We analyze future climate changes in these area using two ensemble-average methods from CMIP5 data. Bayesian Model Averaging shows a better capability to represen...

The objective of this study is to cross-validate 34 Coupled Model Intercomparison Project Phase 5 (CMIP5) historical simulations of precipitation against the Global Precipitation Climatology Project (GPCP) data, quantifying model pattern discrepancies, and biases for both entire distributions and their upper tails. The results of the volumetric hit index (VHI) analysis of the total monthly prec...
