(a) the per capita annual availability of water;
(b) the lowest and the highest average availability of water in the
country with locations/ areas;
(c) the per capita availability of water according to international
norms; and
(d) the regions/districts where water is considered to be scarce,
State-wise ?
THE MINISTER OF STATE IN THE MINISTRY OF WATER RESOURCES ( SMT. BIJOYA CHAKRAVARTY)
(a) & (b) As per the latest assessment (1933) made by the Central
Water Commission (CWC), the average annual water availability in the
river-systems of the country is assessed at 1869 Billion Cubic Metre
(BCM). The per capita water availability in the year 2001 is 1820
cubic metre per year on a national level. The lowest per capita
average availability of water in the country is estimated as 298
cubic metre annually in Sabarmati basin and the highest per capita
average availability of water in the country is estimated as 16,990
cubic metre annually in Minor River Basins Draining into Bangladesh &
Myanmar followed by 13,636 cubic metre annually in Brahmaputra-Barak
Sub-basin.
(c) According to the international criteria, a situation of annual
per capita availability of water of less than 1000 cubic metre is
considered as scarcity condition.
(d) The availability of water is assessed river basin-wise.
Accordingly, the per capita water availability in the Sabarmati
basin; Area of Inland Drainage in Rajasthan Desert; East flowing
rivers between Pennar and Kanyakumari; Pennar; West flowing rivers of
Kutchh, Saurashtra including Luni; Cauvery basin; East flowing rivers
between Mahanadi and Pennar; Tapi and Mahi river basins is less than
1000 cubic metre annually. The River basin-wise water availability &
per capita availability is given at Annex.
