constructed mainly for the purpose of supplying water to agricultural lands
through out the year. When there re no
dams dams, water in rivers flows
continuously in to the oceans and during winter and summer there will not be
enough water for irrigation or for drinking.
of villages is benefited. Civilization
continues to live and flourish around the areas due to dams. Dams enable storage of water and allow controlled
release of water downstream. So
villages are protected from submerging during floods to a good extent. However, there is a risk that if there is
more inflow of water than the reservoir can hold, the surrounding areas can
drown. That would not be the case if
there is no dam.
construction of dams perhaps a thousand villages, have to vacate their lands
and move away from near the dam to relocate elsewhere. The wild life – animals, fauna, flora and
forests, around there is affected. Often
dams are expensive and take decades to complete due to conflicts among local
leaders and population. The benefits and
problems faced by upstream people and those faced by downstream people often
are conflicting. Hence, Construction of dams has not been an easy task
for governments so far. There are many
dams pending construction and stopped in the middle.
is another problem. Salt accumulates due
to dams and irrigation water contains more salt. That has some impact on crops and lands.
Lakhs of farmers
eagerly await release of water from the canals on either side of dams every
season. Many regions which could not be
irrigated due to lack of water, turn into fertile lands. Many people also have found business and
employment in aquaculture activities.
benefit a lot if there is a hydro-electricity generation project along with the
dam. This energy is pollution free,
renewable, cheaper and safe. Beautiful
parks and botanical gardens are constructed and maintained around the
dams. The dams and surrounding areas are
turned in to tourist spots. So many
people visit during rainy season and throughout the year.
Dams are a risk due
to seismic activities and earthquakes. It
is difficult to trust the perfectness in construction. Many people don’t want to live in surrounding
areas. Tribal people have a reason to worry.
Whatever the case
is, dams are very important in India’s agricultural scenario and have a great
role to play in the economic development of India. Millions of people are affected by each dam in India.
