ken betwa river linking project new hurdle
Jan 17, 2017

In news:

The NITI Aayog (National Institution for Transforming India) has recommended that Madhya Pradesh contribute 40 per cent of the project cost, with the Centre contributing 60 per cent. The Ministry of Water Resources (MoWR) has opposed this and requested that 90 per cent of the funds be routed through the Centre.

The project was given a go-ahead by the National Board for Wildlife (NBWL) at a meeting chaired by Minister of State for Environment and Forests but now this new hurdle has arose.

About Project:

  • The main feature of the project is a 230-km long canal and a series of barrages and dams connecting the Ken and Betwa rivers that will irrigate 3.5 lakh hectares in Madhya Pradesh and 14,000 hectares of Uttar Pradesh in Bundelkhand. 
  • The key projects are the Makodia and Dhaudhan dams, the latter expected to be 77 metres high and responsible for submerging 5,803 hectares of tiger habitat in the Panna Tiger Reserve.
  • When, and if, the proposed reservoir is filled to the brim, 6,221 hectares will be inundated — of this, 4,141 hectares is core forest and located inside the reserve. 
  • Chhatarpur, Panna, Tikamgarh, Raisen, and Vidisha districts of Madhya Pradesh and Mahoba, Jhansi and Banda districts of Uttar Pradesh will benefit from irrigation, domestic and industrial water supply and power generation
  • Seventeen lakh residents of nearby towns and villages in both States will benefit from improved drinking water supply and irrigation.

Inter linking of Rivers:

The idea behind ILR is to divert water from surplus rivers in the north and east, which face frequent flooding, to water scarce regions in the west and south, where droughts are a common occurrence.

Component of National River Planning project:

It has two components:

a) Himalayan Component

b) Peninsular Component

c) The Himalayan component envisages construction of storage reservoirs on the main Ganga and Brahmaputra Rivers and their principal tributaries in India and Nepal so as to conserve monsoon flows for irrigation and hydro-power generation, besides flood control.  Links will transfer surplus flows of the Kosi, Gandak and Ghagra to the west.  In addition, the Brahmaputra-Ganga Link will augment dry-weather flow of the Ganga.  Surplus flows that will become available on account of inter-linking of the Ganga and the Yamuna are proposed to be transferred to the drought prone areas of Haryana, Rajasthan and Gujarat.  With this proposal about 14 Mha-m of additional water would be available from these river systems for irrigating an estimated 22 M-ha in the Ganga-Brahmaputra basin apart from Haryana, Punjab, Rajasthan and Gujarat. It would also provide 1120 cumec to Calcutta Port and would provide navigation facility across the country. It will also provide flood moderation in the Ganga-Brahmaputra system. The Himalayan component will benefit not only India but also Nepal and Bangladesh. Fourteen links are proposed in the Himalayan component.

d) Proposed Fourteen Links in the Himalayan Component

1 KOSI-MECHI 2 KOSI-GHAGRA
3 Gandak-Ganga 4 Ghagra-Yamuna
5 Sarda-Yamuna 6 Yamuna-Rajasthan
7 Rajasthan-Sabarmati 8 Chunar-Sone Barrage
9 Sone Dam-South Tributaries of Ganga 10 Brahmaputra-Ganga (MSTG)
11 Brahmaputra-Ganga (JTF)(ALT) 12 Farakka-Sunderbans
13 Ganga-Damodar-Subernarekha 14 Subernarekha-Mahanadi

 Peninsular Rivers Development Component

The main component of Peninsular Rivers Development is the “Southern Water Grid” which is envisaged to link Mahanadi, Godavari, Krishna, Pennar, and Cauvery rivers. The peninsular scheme was envisaged to provide additional irrigation benefits of over 13 million ha. The Peninsular component comprises the following four parts:

  • Diversion of surplus flows of Mahanadi and Godavari to Krishna, Pennar, Cauvery and Vaigai.
  • Diversion of west-flowing rivers of Kerala and Karnataka to the east.
  • Inter-linking small rivers flowing along the west coast, north of Mumbai and south of Tapi.
  • Inter-linking the southern tributaries of Yamuna.

The peninsular component of ILR has 13 major water storage/diversion structures situated in four basins. Three non-storage structures, viz., Dowlaiswaram barrage, Prakasam barrage, and Grand Anicut and storage node (Narayanpur) cater to only irrigation, while six storage nodes, viz., Inchampalli, Almatti, Nagarjunasagar, Pulichintala, Krishnarajasagar, and Mettur will serve both irrigation and power needs. One storage node, viz., Somasila is operated to meet domestic and irrigation needs and two storage nodes, viz., Polavaram and Srisailam are multi-purpose projects serving domestic, irrigation, and hydropower demands.

5 Krishna (Almatti) – Pennar 6 Krishna (Srisailam) – Pennar
7 Krishna (Nagarjunsagar) – Pennar (Somasila) 8 Pennar (Somasila)-Cauvery (Grand Anicut)
9 Cauvery (Kattalai) – Vaigai – Gundar 10 Ken-Betwa
