Our energy and water systems are inextricably linked. Climate change necessitates that we transition to carbon-free energy and also that we conserve water resources as they become simultaneously more in demand and less available.

The continuous expansion of global cropland exerts substantial pressure on natural ecosystems. One option to halt this process is to spare land by achieving high crop yields. In a recent study we estimated how much land could be returned to nature if high-yield farming was realised globally.
