Water is the key limiting factor in socioeconomic and ecological development, but it adversely affected by climate change. The novel virtual water (VW) concept water, energy, food, biodiversity, human health (WEFBH) nexus approach are powerful tools to assess sustainability of a region through lens Climate change-related challenges complex intertwined. This paper analyzed significant WEFBH sectors using multicriteria decision-making (MCDM) analytic hierarchy process (AHP) model. AHP model...

Global agricultural lands are becoming saline because of human activities that have affected crop production and food security worldwide. In this study, the spatiotemporal variability soil electrical conductivity (EC) in Central Asia was evaluated based on high-resolution multi-year predicted EC data, Moderate Resolution Imaging Spectroradiometer (MODIS) land cover product, precipitation, reference evapotranspiration, population count, moisture datasets. We primarily detected pixel-based...

In the context of global warming, sustainability farmland ecosystems is increasingly impacted by multiple disturbances from both natural and human-induced sources. This study constructed a conceptual model indicator system ecosystem resilience (FER) based on disturbance-response processes ecosystems. FER assessment, supported 30 specific indicators, was tested in Ethiopia, one most food-insecure countries world factors impending were discussed obstacle degree values (ODVs). The results...

In this study, the response surface methodology was used to optimize ultrasonic extraction of polysaccharides from Radix pueraria lobata. The first parameter interest investigate its effect on polysaccharide content within Based single-factor experiments analysis, independent variables including time, solid–liquid, and times were for further optimization RPL by Box-Behnken design (BBD). Optimal conditions showed that maximum 1.235 mg/g. molecular weight (Mw), Fourier transformation infrared...
