Taking into consideration that global warming will increase water scarcity in arid and semiarid regions the construction of dams and reservoirs will become an important adaptation strategy.
A dam is a barrier constructed to hold back water and raise its level, forming a reservoir used to generate electricity or as a water supply.
In rural areas with dry seasons and where poverty predominates, small earth dams can be appropriate measures to store water and support irrigated agriculture and gardening. However, the reservoirs are also a risk for the health of the users due to pollution by animals and humans.
Where higher water quantities have to be managed and discharged structures are important, small concrete dams might be appropriate.
