Ken-Betwa project- environmental hazards

Introduction

  • Uttar Pradesh, Madhya Pradesh and the Centre signed a tripartite agreement to transfer “surplus” water from the Ken basin in M.P. to the “deficit” Betwa basin in U.P.

About Ken-Betwa project

  • First mooted in the 1980s, the Ken-Betwa project was taken up seriously only during former Prime Minister Atal Bihari Vajpayee’s regime.
  • The Ken-Betwa project is part of the national river linking project which proposes to connect 14 Himalayan and 16 peninsular rivers with 30 canals and 3,000 reservoirs in order to irrigate 87 million hectares of land.
  • It has the status of a national project, as the Centre will contribute 90% of the cost.
  • It is India’s first river linking project and will take eight years to complete.

Importance of the project

  • The project, the government says, will enhance the irrigation potential of the water-starved Bundelkhand region in U.P. and M.P., facilitate groundwater recharge and reduce the occurrence of floods.
  • According to the Memorandum of Agreement signed, the to-be-built Daudhan dam is expected to irrigate nearly 6,00,000 hectares in four districts in M.P. and 2,51,000 hectares in four districts in U.P. and provide drinking water supply to 41 lakh people in M.P. and 21 lakh in U.P.

Environmental concerns

  • However, the excitement of planners and politicians about this project, which costs ?37,611 crore (2018 figure), is reportedly missing on the ground.
  • In public hearings held in the past, they were divided on political lines and also worried about the loss of the ecosystem and displacement.
  • Of the 12,500 hectares of land to get submerged by the project, more than 9,000 ha are categorised as forest land.
  • The submergence area includes a critically important section of the Panna Tiger Reserve.
    • The Reserve is considered as a shining example of conservation after it successfully improved the tiger and vulture populations.
  • Around 40% of the area of the tiger reserve will be irretrievably damaged if the project is implemented.
  • Also, the project may destroy about 7.2 lakh trees.
  • South Asia Network on Dams, River and People convener Himanshu Thakkar fears that this will affect rainfall in the already parched region.

Cost and benefit

  • The claims of Ken having surplus water may be unrealistic as the river is not perennial — in the past sometimes, it has slowed to a trickle.
  • Another difficulty will be that the Ken flows 60-70 feet lower than the Betwa and at least 30% of the 103 MW power generated will be used for pumping the water up.
  • The Union Ministry and the National Water Development Agency, which is entrusted with the project, have some issues to sort out.
  • These include getting clearance from the Central Empowered Committee of the Supreme Court, which had raised concerns about the project.
  • The cost-benefits calculations of the project also don’t take into consideration the environmental and social impacts.
  • Thus, the benefits do not seem certain and are far outweighed by the costs on the environment.

Way forward

  • It is surprising that alternatives such as water-conservation and water-harvesting methods without building a dam haven’t been seriously considered in the region.
  • Large-scale solutions such as this are not always viable and the best.

Conclusion

  • Given the serious doubts about the benefits of the project and the monumental toll that it would have on the ecosystem, including on carefully preserved wildlife, the Ken-Betwa project seems like a huge, costly mistake.
