(a) whether the Government has categorised the various parts of the country into regions with excessive, normal and minimum rainfall on the basis of rainfall received during the last three years;
(b) if so, the details thereof, year-wise, State-wise and category-wise:
(c) whether the Government has explored the possibilities of channelising the rain water from excessive rainfall regions to minimum rainfall regions; and
(d) if so, the details thereof?
THE MINISTER OF STATE (INDEPENDENT CHARGE) MINISTRY OF SCIENCE AND TECHNOLOGY, MINISTRY OF
EARTH SCIENCES, MINISTER OF STATE IN THE PRIME MINISTER’S OFFICE, MINISTER OF STATE IN THE
MINISTRY OF PERSONNEL, PUBLIC GRIEVANCES & PENSIONS AND MINISTER OF STATE IN THE MINISTRY OF
PARLIAMENTARY AFFAIRS (SHRI PRITHVIRAJ CHAVAN)
(a)-(b) No Madam. However, India Meteorological Department (IMD) prepares rainfall distribution
state-wise, meteorological subdivision wise and for country as a whole in the time scale of
weekly, monthly, seasonal and annual. Distribution of rainfall during the last three years
shows year to year variability with 6-Nos., 4-Nos. and 19 -Nos. of states falling under
rainfall deficient category during monsoon seasons of 2007, 2008 and 2009 respectively.
Similarly on annual time scale 4-Nos., 6-Nos and 19-Nos of states were deficient in 2007,
2008 and 2009 respectively. Details are presented in Annexure-I and Annexure-II.
(c)-(d) The Ministry of Water Resources and Central Water Commission(CWC) in 1980 had
started exploring the possibilities of channelizing the excess water through a National
Perspective Plan for water resources development in India comprising two components:
Himalayan and Peninsular Components. A major feature of this plan was transfer of water
from water surplus basins to water deficit basins/ regions in India by Inter Basin Water
Transfer Projects.
The National Water Development Agency (NWDA) was set up in 1982 as an autonomous society
under Ministry of Water Resources to give concrete shape to these proposals by carrying out
the detailed studies, surveys and investigation work and to prepare feasibility reports of
the links under the National Perspective Plan. The NWDA, after carrying out detailed studies,
identified 30 links: 14 under Himalayan Component; and 16 under Peninsular Component for
preparation of Feasibility Reports. NWDA has completed the pre-feasibility reports for all
the links and Feasibility study of 16 links. The Feasibility Reports for remaining links are
at various stage of completion. The NWDA had taken up the discussions with the concerned
State Governments for building the consensus for preparation of Detailed Project Report (DPR)
of individual link proposals. After consensus is reached amongst the concerned States for
a particular link, the work for preparation of DPR of that link shall be taken up by NWDA.
