What Happens to Land when a Dam Is Built?
People who live in area that will be covered by the reservoir must move – resettlement.
Owners in good land-tenure countries are compensated and move elsewhere, usually to nearby cities.
Inhabitants in rural areas or informal settlements in most countries are either evicted or resettled.
Resettlement programs have been conducted for decades, some successfully
Future dams will probably spur more rural-urban migration, already underway for several generations
Land cover in reservoir area cleared (seldom)
Construction sites and housing built for workers and support populations
When reservoir is filled, people are attracted to water
Transportation
Agriculture – irrigation, access to markets (large corporations)] Subsistence – Haiti – upstream settlement -> deforestation -> reservoir sedimentation
Recreation – infrastructure and access
Full reservoir inundates former floodplains and riparian areas
Inundates fertile bottomland soils
Removes riparian corridor for organism movement, sediment/biogeochemical function
Formerly terrestrial land is inundated, either permanently or intermittently
Afforestation – some nations have programs in upstream parts of the basin to reduce erosion
Downstream:
flow moderated, people plant or build in previous floodplains
Fertile soils in former floodplain
Subject to catastrophic flooding – dam failure happens!
Flow moderated, earlier livelihood methods based on flooding can be lost (Egypt, Cambodia)
Drought mitigation (Egypt, Thailand)
Flood mitigation (Vietnam Mekong Delta)
