National Perspective Plan( NPP) Printable Version
 

 At the time of independence the country had a population of about 400 million and faced severe food crisis.  At that time the irrigation potential of the country was only about 20 Mha. After independence massive programme of irrigation was launched for development and utilization of both surface and ground water resources.  This resulted in green revolution, which helped to transform the country from the state of food scarcity to food self-sufficiency.  Due to these massive efforts, by the year 1979 the irrigation potential of the country could increase to 57 Mha with the use of high yielding varieties possible under irrigation and with increased use of fertilizers. The food production of the country could be increased to about 125 to 130 million tones by the same time.  However, rate of increase in food production could just managed to equal the rate of population growth.  

The water is main input to the agriculture and also an important element for the life of human kind, its optimal utilization is necessary. With a view to harness the water resources of the country optimally, Dr. K.L. Rao, the then irrigation Minister, in the year 1972 had mooted the idea of interlinking of rivers by connecting the Ganga with the Cauvery river.  Subsequently, in 1977 Capt. Dastur initiated the concept of a Garland Canal around the Himalayan, Central and Peninsular India. The proposals although received very good response from all sectors of communities, but not found techno-economical feasible for implementation.

 

The continued interest shown by many people engaged in Water Resources Development gave further impetus to study inter basin water transfer proposals in more details. The then Ministry of Irrigation (now Ministry of Water Resources) and Central Water Commission formulated a National Perspective Plan (NPP) for Water Resources Development in 1980, envisaging interbasin transfer of water from surplus basins to deficit ones with a view to minimize the regional imbalances and optimally utilize the available water resources.

 

National Perspective Plan comprises of two components viz. Himalayan Rivers Development and Peninsular Rivers Development.

 

Himalayan Rivers Development:   

           

Himalayan Rivers Development Component   envisages construction of storage reservoirs on the principal tributaries of Ganga and Brahmaputra rivers in India, Nepal and Bhutan along with interlinking of river systems to transfer surplus flows of the eastern tributaries of the river Ganga to the west, apart from linking of the main Brahmaputra and its tributaries with Ganga and Ganga with the river Mahanadi. 

  

Peninsular Rivers Development:

 

Peninsular Rivers Development Component  is divided into four major parts viz.

 

 

1.     Interlinking of Mahanadi-Godavari-Krishna-Cauvery rivers and     building  storages at potential sites in these basins. 

 

This part involves interlinking of the major river systems where surpluses from the Mahanadi and the Godavari are intended to be transferred to the needy areas in the south, through Krishna and Cauvery rivers. 

 

2.       Interlinking  of west flowing rivers, north of  Bombay  and  south
   of  Tapi
.

 

This scheme envisages construction of as many optimal storages as possible on these streams and interlinking them to make available appreciable quantum of water for transfer to areas where additional water is needed.   The scheme provides for taking water supply canal to the metropolitan areas of Mumbai; it also provides irrigation in the coastal areas in Maharashtra

 

3.      Interlinking of Ken-Chambal 

 

The scheme provides for a water grid for Madhya Pradesh, Rajasthan and Uttar Pradesh   and interlinking canal backed by as many storages as possible.

 

4.      Diversion of other west flowing rivers

 

The high rainfall on the western side of the Western Ghats runs down into numerous streams which discharge into the Arabian Sea. The construction of an interlinking canal system backed up by adequate storages could be planned to meet all requirements of Kerala as also for transfer of some waters towards east to meet the needs of  drought  affected areas.

 

In the proposals of NPP, the transfer of water has been proposed mostly by gravity, lifts were kept minimal and confined to around 120 m and only surplus flood water after meeting all in-basin requirement in foreseeable future has been planned for transfer to water deficit areas.
