3-Water scarcity is the lack of fresh water resources to meet water demand. It affects every continent and was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade.[1] It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment.[2] One-third of the global population (2 billion people) live under conditions of severe water scarcity at least 1 month of the year.[3][4][5][6] Half a billion people in the world face severe water scarcity all year round.[3] Half of the world’s largest cities experience water scarcity.

Answer 2

Hello bro

Q1)

. Regulating and damming of rivers affect their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir.

2.It affectspoorer habitats for the rivers aquatic life.

3.Damsalso fragment rivers making it difficult for spawning.

4.The reservoirs that are created onthe floodplains also submerge the existing

vegetation and soil leading to its decomposition over a period of time

Q2)

Many multi-purpose projects have come under scrutiny and opposition due to various reasons. Some of the important reasons are:

Projects like Sardar Sarovar Project and the Tehri Dam Project have faced opposition from the locals because of the displacement of local communities. Movements like 'Narmada Bachao Andolan' and 'Tehri Dam Andolan' have resisted the projects because the locals have lost their land holdings and thus their livelihoods.Forests and wild-life gets submerged and this damage is irreversible or measurable.Dams and reservoirs alter the sedimentation of the rivers. There is excessive sediment deposit at the reservoir and the lower reaches have a rockier river bed. This is because dams and reservoirs to a large extent seive the river off its sediment transport. The rockier beds in turn hamper the aquatic life in the rivers.The migration of aquatic fauna is hindered due to dams.In floodplains, large areas are submerged due to reservoirs and this leads to soil decomposition and fertility is washed away over a period of time.

Hope helps....
