The increasingly adverse impacts of climate change (e.g., rainfall patterns, droughts, and floods), coupled with the ever-increasing water demands, are often translated into a contingent liability for users’ communities. Additional complexities arise due to competing priorities, rights, transboundary sources. Therefore, conventional management practices should shift toward more comprehensive responsive integrative approaches, even systems limited data. Furthermore, managers must prioritize...

ABSTRACT Mediterranean‐African countries (MACs) face a major water crisis. The annual renewable resources are close to the 500 m 3 /capita threshold of absolute scarcity, and withdrawals exceed total by 30%. Such low availability curbs economic development in agriculture, which accounts for 86% freshwater consumption. analysis current situation wastewater treatment, irrigation, management MACs research projects targeted these indicates need 1) an enhanced capacity analyze stress, 2)...

Water shortages, overexploitation, and sectoral conflicts have prompted the use of treated wastewater (TWW) in agriculture. While TWW provides essential nutrients, improper management can harm soil crops. To address this, case studies from Jordan Palestine—where alfalfa citrus crops are exclusively irrigated with TWW—were conducted to identify suitable irrigation schedules assess adverse impacts on soils. The Safe Irrigation Management (SIM) model was used simulate 2021, considering quality,...

Efficient irrigation management is crucial for optimizing water use and productivity in agriculture, particularly water-scarce regions. This study evaluated the effectiveness of soil-based weather-based using a low-cost (DIY) Internet Things (IoT) capacitive soil moisture sensor on drip-irrigated lettuce. A field experiment was conducted to compare efficiency between two approaches. The system utilized real-time data from IoT sensors guide scheduling, while relied evapotranspiration data....

ABSTRACT The use of treated wastewater (TWW) as an alternative resource to fresh water (FW) for irrigation purposes is becoming increasingly important, especially in semiarid and arid regions. However, achieving success crop production largely depends on the adoption appropriate on‐farm management strategies aimed at optimizing yields, maintaining soil productivity safeguarding environment. For this purpose, predictive models are particular interest. A safe (SIM) model developed tested...
