Need for a National Water Policy
1.1
Water is a prime natural resource, a basic human need and a precious national
asset. Planning, development and
management of water resources need to be governed by national perspectives.
1.2
As per the latest assessment (1993), out of the total precipitation, including
snowfall, of around 4000 billion cubic
metre in the country, the availability from surface water and replenishable
ground water is put at 1869 billion
cubic metre. Because of topographical and other constraints, about 60% of this
i.e. 690 billion cubic metre from
surface water and 432 billion cubic metre from ground water, can be put to beneficial
use. Availability of water is highly uneven in both space and time. Precipitation
is confined to only about three or four
months in a year and varies from 100 mm in the western parts of Rajasthan to
over 10000 mm at Cherrapunji in
Meghalaya. Rivers and under ground aquifers often cut across state boundaries. Water, as a resource is one and indivisible:
rainfall, river waters, surface ponds and lakes and ground water are all part of one system.
1.3
Water is part of a larger ecological system. Realising the importance and
scarcity attached to the fresh water, it
has to be treated as an essential environment for sustaining all life forms.
1.4
Water is a scarce and precious national resource to be planned, developed,
conserved and managed as such, and on an
integrated and environmentally sound basis, keeping in view the socio-economic
aspects and needs of the States. It is
one of the most crucial elements in developmental planning. As the country has entered the 21st century, efforts to develop,
conserve, utilise and manage this important resource in a sustainable manner, have to be guided by the
national perspective.
1.5
Floods and droughts affect vast areas of the country, transcending state
boundaries. One-sixth area of the
country is drought-prone. Out of 40 million hectare of the flood prone area in
the country, on an average, floods
affect an area of around 7.5 million hectare per year. Approach to management
of droughts and floods has to be
co-ordinated and guided at the national level.
1.6
Planning and implementation of water resources projects involve a number of
socio-economic aspects and issues such
as environmental sustainability, appropriate resettlement and rehabilitation of
project-affected people and livestock,
public health concerns of water impoundment, dam safety etc. Common approaches
and guidelines are necessary on these matters. Moreover, certain problems and weaknesses
have affected a large number of water resources projects all over the country.
There have been substantial time and
cost overruns on projects. Problems of water logging and soil salinity have
emerged in some irrigation commands,
leading to the degradation of agricultural land. Complex issues of equity and social
justice in regard to water distribution are required to be addressed. The
development, and overexploitation of groundwater resources in certain parts of
the country have raised the concern and need for judicious and scientific resource management and
conservation. All these concerns need to be addressed on the basis of common policies and strategies.
1.7
Growth process and the expansion of economic activities inevitably lead to
increasing demands for water for diverse
purposes: domestic, industrial, agricultural, hydro-power, thermal-power,
navigation, recreation, etc. So far, the
major consumptive use of water has been for irrigation. While the gross irrigation potential is estimated to have
increased from 19.5 million hectare at the time of independence to about 95 million hectare by the end of the
Year 1999-2000, further development of a substantial order is necessary if the food and fiber needs of our
growing population are to be met with. The country’s population which is over 1027 million (2001
AD) at present is expected to reach a level of around 1390 million by 2025 AD
1.8
Production of food grains has increased from around 50 million tonnes in the
fifties to about 208 million tonnes in the Year 1999-2000. This will have to be
raised to around 350 million tonnes by the year 2025 AD. The drinking water
needs of people and livestock have also to be met. Domestic and industrial water
needs have largely been concentrated in or near major cities. However, the
demand in rural areas is expected to increase sharply as the development
programmes improve economic conditions of the rural masses. Demand for water
for hydro and thermal power generation and for other industrial uses is also increasing
substantially. As a result, water, which is already a scarce resource, will
become even scarcer in future. This underscores the need for the utmost
efficiency in water utilisation and a public awareness of the importance of its
conservation.
1.9
Another important aspect is water quality. Improvements in existing strategies,
innovation of new techniques resting on a strong science and technology base
are needed to eliminate the pollution of surface and ground water resources, to
improve water quality. Science and technology and training have to play important
roles in water resources development and management in general.
1.10
National Water Policy was adopted in September, 1987. Since then, a number of
issues andchallenges have emerged in the development and management of the
water resources. Therefore, the National Water Policy (1987) has been reviewed
and updated.
Information System
2.1
A well developed information system, for water related data in its entirety, at
the national / state level, is a prime requisite for resource planning. A
standardised national information system should be established with a network of data banks and
data bases, integrating and strengthening the existing Central and State level agencies and improving the
quality of data and the processing capabilities.
2.2
Standards for coding, classification, processing of data and methods /
procedures for its collection should be
adopted. Advances in information technology must be introduced to create a
modern information system promoting free
exchange of data among various agencies. Special efforts should be made to
develop
and
continuously upgrade technological capability to collect, process and disseminate
reliable data in the desired time frame.
2.3
Apart from the data regarding water availability and actual water use, the
system should also include comprehensive
and reliable projections of future demands of water for diverse purposes.
Water Resources Planning
3.1
Water resources available to the country should be brought within the category
of utilizable resources to the maximum possible extent.
3.2
Non-conventional methods for utilisation of water such as through inter-basin
transfers, artificial recharge of ground
water and desalination of brackish or sea water as well as traditional water
conservation practices like rainwater
harvesting, including roof-top rainwater harvesting, need to be practiced to
further increase the utilisable water
resources. Promotion of frontier research and development, in a focused manner,
for these techniques is necessary.
3.3
Water resources development and management will have to be planned for a
hydrological unit such as drainage basin
as a whole or for a sub-basin, multi-sectorally, taking into account surface
and ground water for sustainable use
incorporating quantity and quality aspects as well as environmental
considerations. All individual
developmental projects and proposals should be formulated and considered within
the framework of such an overall plan keeping in view the existing agreements /
awards for a basin or a subbasin so that the best possible combination of
options can be selected and sustained.
3.4
Watershed management through extensive soil conservation, catchment-area
treatment, preservation of forests and increasing the forest cover and the
construction of check-dams should be promoted. Efforts shall be to conserve the
water in the catchment.
3.5
Water should be made available to water short areas by transfer from other
areas including transfers from one river
basin to another, based on a national perspective, after taking into account
the requirements of the areas / basins.
Institutional Mechanism
4.1
With a view to give effect to the planning, development and management of the
water resources on a hydrological unit
basis, along with a multi-sectoral, multi-disciplinary and participatory
approach as well as integrating quality,
quantity and the environmental aspects, the existing institutions at various
levels under the water resources sector
will have to be appropriately reoriented / reorganised and even created,
wherever necessary. As maintenance of water resource schemes is under non-plan
budget, it is generally being neglected. The institutional arrangements should
be such that this vital aspect is given importance equal or even more than that
of new constructions.
4.2
Appropriate river basin organisations should be established for the planned
development andmanagement of a river basin as a whole or sub-basins, wherever
necessary. Special multi-disciplinary units should be set up to prepare
comprehensive plans taking into account not only the needs of irrigation but
also harmonising various other water uses, so that the available water resources
are determined and put to optimum use having regard to existing agreements or
awards of Tribunals under the relevant laws. The scope and powers of the river
basin organisations shall be decided by the basin states themselves.
Water Allocation Priorities
5.
In the planning and operation of systems, water allocation priorities should be
broadly as follows:
·
Drinking water
·
Irrigation
·
Hydro-power
·
Ecology
·
Agro-industries and non-agricultural industries
·
Navigation and other uses.
However,
the priorities could be modified or added if warranted by the area / region
specific considerations.
Project Planning
6.1
Water resource development projects should as far as possible be planned and
developed asmultipurpose projects. Provision for drinking water should be a
primary consideration.
6.2
The study of the likely impact of a project during construction and later on
human lives, settlements, occupations, socio-economic, environment and other
aspects shall form an essential component of project planning.
6.3
In the planning, implementation and operation of a project, the preservation of
the quality of environment and the ecological balance should be a primary
consideration. The adverse impact on the environment, if any, should be
minimised and should be offset by adequate compensatory measures. The project
should, nevertheless, be sustainable.
