Yes, they do. Dams can cause huge environmental degradation:
1) disturb natural fluctuations in water source
2) water quality can be degraded
3) transport of sediment along the rive is disrupted
4) reservoirs can emit climate changing greenhouse gases

How do floods and drought cause land degradation?
Floods can cause land degradation by eroding topsoil, carrying away nutrients, and saturating the soil with water which can lead to soil compaction and loss of soil structure. Droughts can cause land degradation by reducing vegetation cover, making the soil vulnerable to erosion, and depleting soil moisture, which can lead to desertification and loss of fertility in the soil.
What do dams cause?
dams cause many fishs' life cycle
How does mining and quarrying cause land degradation?
Mining and quarrying cause land degradation by removing vegetation, disrupting soil structure, and altering the natural landscape. This can lead to erosion, loss of biodiversity, and contamination of soil and water supplies, impacting both the local ecosystem and surrounding communities. Additionally, the use of heavy machinery and explosives further contributes to land degradation by compacting soil and causing physical damage to the land.
Do dams flood land?
yes, dams can flood lands .
What is the principal cause of soil degradation along the Murray River?
The principal cause of soil degradation along the Murray River is improper land use. Certain agricultural practices cause erosion, whilst over-iriigating causes increased salinity.
What causes the problem of land degradation in Punjab?
the main causes for the land degradation in the punjab is theintensive cultivation.
Does dams cause earthquakes?
no
What is the effects of land?
Land pollution normally becomes a hazard or endangers the life of animals that live in the given area. Land pollution may also cause a degradation of vegetation and natural habitats.
How does mining cause land degradation?
Mining causes land degradation through activities such as deforestation, soil erosion, and contamination of soil and water sources with chemicals used in the mining process. This can lead to loss of biodiversity, disruption of ecosystems, and reduced soil fertility, impacting the overall health and productivity of the land.
What is the effect of land pollution?
Land pollution normally becomes a hazard or endangers the life of animals that live in the given area. Land pollution may also cause a degradation of vegetation and natural habitats.
Can dams cause droughts?
yes
How the building of dams affects the lives of the people and the ecology in the region?
Depends on the size of the dam, and how the water is managed. Big dams will flood big areas of land, and limit the amount of water flowing downstream, which can cause drought. Dams can also stop seasonal flooding, which the wildilfe might have adapted to.
