The 2020 edition of the UN World Water Development Report addresses the critical linkages between water and climate change in the context of sustainable development. It also serves as a guide for concrete actions to address these challenges. It outlines actions, supported by examples from across the world, in three areas: first, enabling people to adapt to the impacts of climate change; second, improving the resilience of livelihoods; and, third, reducing the drivers of climate change. Critically, measures to improve the efficiency of water use in agriculture is inextricably linked to multiple SDGs. These include those related to zero hunger (SDG 2), availability and access to water (SDG 6), climate action (SDG 13), and promoting the sustainable use of ecosystem services (SDG 15).
The Report concludes that reducing both the impacts and drivers of climate change will require substantial changes in the way we use and reuse the Earth’s limited water resources. The experience and expertise needed to achieve this goal are brought together in the Report through UN-Water’s Members and Partners. It will support policy makers in tackling the challenges of climate change by harnessing the wide-ranging opportunities that improved water management offers for adaptation, mitigation and resilience in a rapidly changing world.
