Crop water management
Agricultural practices that reduce water use or its impacts

- Pathways to sustainable intensification through crop water management (2016)
- reflects on how the global crop water management simulations of Jägermeyr et al could interact with: (1) farm size at more local scales, (2) downstream water users at the river basin scale, as well as (3) food trade and (4) demand-side food system strategies at the global scale.
- Water productivity in rainfed systems: overview of challenges and analysis of opportunities in water scarcity prone savannahs (2007)
- Studies the consumptive green water productivity (WP) dynamics of rainfed farming systems, and shows that the often assumed linear relationship between evapotranspiration (ET) and yield (Y) does not translate into constant WP over a wide range of yields
- Integrated soil and water management, focusing on dry spell mitigation and soil fertility can potentially more than double on-farm yields, while simultaneously improve green (ET) WP and productive green (T) WP
- Integrated crop water management might sustainably halve the global food gap (2016)
- Simulates potential to increase yield by increasing irrigation water productivity, expanding irrigation with saved water, and optimizing use of rainfall (alleviated soil evaporation, enhanced infiltration, water harvesting for supplemental irrigation) under current and projected future climate (from 20 climate models, with and without beneficial CO2 effects).
