Service Description:

Drought

Extended periods with below average rainfall are difficult for people and wildlife, especially in arid regions that are already stressed by a lack of water. During droughts, water scarcity can threaten irrigation water for farms and drinking water for local communities. These impacts can be especially severe in communities without robust water infrastructure. Climate change is expected to make droughts more frequent and severe, further stressing people and wildlife. Around our homes, native landscaping and reducing water-demanding lawns can help conserve water and support wildlife. Managing water under increasingly severe drought will require creative solutions to ensure that the limited water we have provides the greatest benefits for people and wildlife.

Data Source(s)

Carrão H, Naumann G, Barbosa P. 2016. Mapping global patterns of drought risk: An empirical framework based on sub-national estimates of hazard, exposure and vulnerability. Global Environmental Change 39:108–124.

Processing

We mapped the current footprint of drought as a binary surface by identifying 3-km cells that had a drought hazard score of 0.55 or greater on a scale of 0-1 (Carrão 2016).

Most Relevant IUCN - CMP Unified Direct Threat Classification
