Water Scarcity and Wastewater Reuse in Crop Irrigation
, 2020 Due to climate change, two-thirds of mankind will face water scarcity by 2025, while by 2050, global food production must increase by at least 50% to feed 9 billion people.

Irrigable measures for weighted irrigation plans
Networks & Heterogeneous Media, 2021 <p style='text-indent:20px;'>A model of irrigation network, where lower branches must be thicker in order to support the weight of the higher ones, was recently introduced in [<xref ref-type="bibr" rid="b7">7</xref>]. This leads to a countable family of ODEs, describing the thickness of every branch, solved by backward induction.

Half of twenty-first century global irrigation expansion has been in water-stressed regions
Nature WaterThe expansion of irrigated agriculture has increased global crop production but resulted in widespread stress on freshwater resources. Ensuring that increases in irrigated production occur only in places where water is relatively abundant is a key ...

Warming of hot extremes alleviated by expanding irrigation
Nature Communications, 2020 Irrigation affects climate conditions – and especially hot extremes – in various regions across the globe. Yet how these climatic effects compare to other anthropogenic forcings is largely unknown.
