/ The demand for water to support irrigated agriculture has led to the demise of wetlands and their associated wildlife for decades. This thirst for water is so pervasive that many wetlands considered to be hemispheric reserves for waterbirds have been heavily affected; for example, the California and Nevada wetlands in North America, the Macquarie Marshes in Australia, and the Aral Sea in cent...
Irrigated agriculture consumes the largest share of available fresh water, and awareness of the spatial distribution and application rates is paramount to a functional and sustainable communal consumptive water use. This remote sensing study leverages surface energy balance fluxes and vegetation indices to classify and map the spatial distribution of irrigated and non-irrigated croplands. The p...
this research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. this experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of chenran township. the results ...
Future irrigated agriculture will be strongly affected by climate change and agricultural management. However, the extent that management adaptation can counterbalance negative climate-change impacts achieve sustainable production remains poorly quantified. Such quantification is especially important for Indus basin, as essential its food security highly increasing temperatures changing water a...
