Climate change is increasing evapotranspiration in the European Alps and causing a decline in surface water supply in the region. Understanding future changes in surface runoff is essential for managing the water supply for over 170 million people.
The United Nations has set a Sustainable Development Goal to end world hunger by 2030. Increasing crop yields is necessary to achieve this goal. However, intensive irrigation practices can also increase the uptake of ozone by plants, damaging sensitive leaf tissues. Lack of ozone pollution mitigation efforts may prevent future progress towards global food security.
