Salt accumulations in aquifers significantly affect and transform the conjunctive use of surface water groundwater supporting irrigated agriculture. accumulates under many semi-arid lands where pumping has lowered levels enough to prevent drainage saline from basin. This paper provides new insights into optimal management pumping, recharge, water, cropping patterns with salinity hydrologic vari...

Agricultural lands occupy 37% of the earth's land surface. Agriculture accounts for 52 and 84% of global anthropogenic methane and nitrous oxide emissions. Agricultural soils may also act as a sink or source for CO2, but the net flux is small. Many agricultural practices can potentially mitigate greenhouse gas (GHG) emissions, the most prominent of which are improved cropland and grazing land m...
