AMUN_SHC Model for Assessing Some Environmental Impacts of Global Climatic Changes on the Agroecosystem’s Continuum |Biomedgrid

Drought, heat socks, and soil salinization are from the abiotic devastating effects of global climatic changes [1]. They affect negatively the agro-ecosystem reducing water and nutrient uptake by plants' roots and accordingly yield and plantation properties. They are common in MENA countries with a degree of extend differs from one to another according to the standards of living, poverty and the ways the governments can deal with the IPCC advice. Egypt takes the advance in the environmental policies should be adopted for mitigating the greenhouse gases emissions. Egyptian Dabaa Nuclear Power Plant is a good example for reducing the dependence upon the fossil fuel to let the engines start. Bahr Al-Baqar Agricultural Wastewater Treatment Plant, the biggest agricultural wastewater treatment plant in the world is another example dealing with the environmental policies of cutting down, reduce, recycle, or safe dispose of the gas and liquid emissions, respectively. Modifying the Richard's equation in order to assess the impact of drought and salinity in arid and semi-arid zones of MENA countries allowed us to discover a new soil hydro-physical property, soil hydraulic capacitance, which determines the type of plants' roots water uptake in accordance with stress, strain, and weathered controlled relationships. AMUN_SHC Model considers the additive effect of soil water potential, SSIMOD, during the reuse of low water quality or treated waste water in agricultural development [2-4].
