a presentation on multi-purpose projects and disadvantages of Multipurpose projects

2. What is a multi purpose project
A multipurpose project is a large scale hydro project often
including dams for water retention , canals for irrigation,
water processing and pipe lines to supply water to cites and
power generation. These often include transportation
improvements and industrial growth. They are also
developed to reduce the dangers of flooding.

• UTTAR PRADESHRIHAND DAM
• KARNATAKATUNGABHADRA DAM
• TAMIL NADUBHAVANISAGAR DAM
• SITUATED INPROJECT

10. The project will inundate thousands of acres of forests and
agricultural land, a devastating blow to human lives and
biodiversity.
The sheer size of the project, the Sardar Sarovar dam could bring
about some of the worst environmental destruction in India.

11. If completed, several hundred square miles of forest would
disappear, destroying precious habitat for tigers, panthers,
sloth bear, barking deer, several rare tree species, and
hundred of plants with medicinal potential.
It may damage or destroy river based fisheries.

12. These projects also generally displace hundreds of not
millions of people from very fertile land thus reducing the
productivity of these people.
They take away their livelihood and their homes of many
generations.

13. • Natural flow of rivers is affected causing poor flow of
sediments
• Excessive sedimentation of the reservoir
• Reservoirs submerge existing vegetation and soil leading to its
decomposition
