Food and water scenarios for the Karkheh River Basin, Iran por Marjanizadeh, S., Fraiture, Charlotte de, Loiskandl, W.

“…Examining three scenarios to the year 2025, the authors of this study find: (1) business as usual leads to an aggravation of groundwater overdraft and may jeopardize the ecosystem services provided by the Hawr Al Azim marsh area; (2) giving priority to environmental flow requirements and restoring groundwater tables leads to a shortfall in wheat production; but (3) reducing agricultural water demand could maintain a certain level of food production. …”

Groundwater governance and adoption of solar-powered irrigation pumps: experiences from the eastern Gangetic Plains por Bastakoti, Ram C., Raut, Manita, Thapa, Bhesh Raj

“…However, because low operating costs for SPIPs does little to incentivize farmers to use water efficiently, one critical question is how to balance equitable access to SPIPs while ensuring groundwater overdraft is not perpetuated. Farmers’ awareness of efficient water management options is crucial to avoid overextraction of groundwater.…”
