Kerala will prevent implementation of Pamba-Achankovil-Vaippar river link project

Kerala government is taking all precautions to prevent the implementation of the Pamba-Achankovil-Vaippar river link project, citing the reason that Kerala does not have excess water to divert it into Tamil Nadu.

ABOUT THE PAMBA-ACHANKOVIL-VAIPPAR RIVER LINK PROJECT

Pamba-Achankovil-Vaippar-river-link-project

  • The river link proposal envisages diversion of water from the Pamba and Achankovil rivers in Kerala to the Vaippar basin in Tamil Nadu.
  • It is listed among the river linking projects of the National Water Development Agency (NWDA).
  • The project envisages irrigation in Tirunelveli, Virudhunagar and Thoothukudi in Tamil Nadu, generation of hydel power and regulate release of water during lean periods to Kerala.

RIVER INTERLINKING

  • River Linking is a project of linking two or more rivers by creating a network of manually created reservoirs and canals.

BENEFITS OF RIVER INTERLINKING

  • Drought, floods and shortage of drinking water: Solve the problem of drought and flood, because at the time of need, the river which causes flood can give water to the area of river which have a shortage of water.
  • Population and food security: In a tropical country like India with high evapotranspiration, food security can be achieved with water security which in turn is achieved by pumping water to uplands from water surplus lower elevation river points up to sea level.
  • Salt export needs: When sufficient salt export is not taking place from a river basin to the sea to harness the river water fully, it leads to river basin closer. Interlinking water surplus rivers with water deficit rivers is needed for the long term sustainable productivity of the river basins and for mitigating the anthropogenic influences on the rivers by allowing adequate salt export to the sea in the form of environmental flows.
  • Navigation: Interlinking of river provides water navigation routes that are cleaner and have low carbon footprint.
  • Boost to economy: Interlinking creates a new occupation for people living in and around these canals.

DISADVANTAGES OF RIVER INTERLINKING

  • Usually rivers change their course and direction in about 100 years and if this happens after interlinking, then the project will not be feasible for a longer run.
  • Due to interlinking of rivers, there will be decrease in the amount of fresh water entering seas and this will cause a serious threat to the marine life system and will be a major ecological disaster.
  • Due to the creation of Canals and Reservoirs, huge amount of area which is occupied by the people will be submerged leading to displacement of people and government will have to spend more to rehabilitate these people.
  • The amount required for these projects is so huge that government will have to take loans from the foreign sources which would increase the burden on the government and country will fall in a debt trap.
  • Since water is an emotive issue, none of the water-rich states would like to accept that they have surplus water to spare.
