National Rainfed Area Authority (NRAA)
Rain-dependent areas can be broadly split into
two: 'dry lands', which receive less than 750 mm of rain a year; and rainfed
areas, which receive more than 750 mm. Comprising arid and semi-arid
ecosystems, dry lands stretch from Gujarat in the west till Eastern Madhya
Pradesh; and from Rajasthan till the southern tip of India.
Basic Facts- Extent of problem of Rainfed
Agriculture In India, about 60% of total net
sown area comes under rainfed lands. Rainfed crops account for 48 percent area
under food crops and 68 percent under non-food crops.
The remaining 60%, which accounts for a
substantial part of agricultural output, is rain-dependent.
India ranks first among the rainfed
agricultural countries of the world in terms of both extent and value of
produce. Due to population pressure on agricultural lands, the poverty is
concentrated in rainfed regions. The climate in India's rainfed regions is
characterized by complex climatic deficiencies, manifested as water scarcity
for rainfed crop production. The climate is largely semi-arid and dry sub-humid
with a short (occasionally intense) wet season followed by long dry season.
Rainfall is highly unreliable, both in time and space, with strong risks of dry
spells at critical growth stages even during good rainfall years. The
fluctuations are due to numerous factors affecting the monsoonal climate
including the atmospheric circulation and strong links to ENSO phenomenon in
the Pacific Ocean.
Characteristics and issues with Rainfed
Agriculture
Rainfed
areas in India are highly diverse, ranging from resource rich areas to
resource-constrained areas. Some of the resource rich areas are highly
productive and have experienced widespread adoption of technology. However,
most of the areas are resource constrained and dry areas.
In the resource constrained and dry areas, the
farming is a survival mechanism rather than a growth oriented activity.
Rainfed agriculture is practiced under a wide
variety of soil type, agro-climatic and rainfall conditions ranging from 400 mm
to 1600 mm per annum.
Rainfed Crops are prone to breaks in the
monsoon during the crop growth due to water stress. This water stress may be
due to variability of rainfall, delay in sowing, diversity in crop management
practice and variability of the soil type. The prolonged breaks can result in
partial o r complete failure of the crops.
Issues Related to Rainfed Farming
Issue
-1 : Farmer suicides in Rainfed areas
In past, the Rainfed farming system was mainly
dependent upon the locally available inputs (seeds, manures, animal draft) and
used to grow a number of crops, which were able to withstand drought-like
situation. However, in recent times, the cropping systems have changed and
currently the farmers in these rainfed areas have limited options. Many of the
farmers in these regions started cultivating high value crops which requires
intensive use of costly inputs (chemical fertilizers/ pesticides, hybrid seeds,
life saving irrigation, farm energy etc.) and find it difficult to manage the
resources on their own. This is the major reason of growing farm suicides in
rainfed areas.
Issue 2: Green Revolution – Rainfed Areas –
Groundwater Problem:
Green Revolution bypassed the less-favored
rainfed areas which were not the partners in this process of agricultural
transformation. Green Revolution was designed around growing high-yielding
varieties of wheat and rice, which needed plenty of water and chemical inputs.
The entire agricultural research framework, incentive structure, price support,
input subsidies, extension system were designed to 'flow' along with
irrigation. In the floodplains of the north, the farmers, realising rainfall
risk was a thing of the past, switched to HYVs because canals were there for
irrigation. However, the story was different in the drylands. Here, seeds and
fertilizers reached but water did not reach. Those who wished to adapt to the
new seeds and fertilizers, created the predictable water supply for themselves.
When electricity came, these farmers invested in groundwater pumps. The
result was tube wells became the mainstay of irrigation in India. According to
a Planning Commission report, titled 'Synopsis of Groundwater Resources in
India', in 1960-61, canals and tanks accounted for 61% of non-rain water for
irrigation, compared to 0.6% for tube wells. In 2002-03, the share of canals
and tanks was down to 33%, while tube wells had increased to 39%.
Issue 3: Green Revolution – Rainfed areas -
Change in the Cropping patterns:
To
reduce their vulnerability to rains, farmers in some areas grew crops such as
jowar, bajra and pulses. These crops are low-yielding, but less affected by
variations in rainfall. This saved the farmers from the risky nature of farming
in rainfed and dry areas. In the same field, they planted multiple
crops. For instance, Jowar or pulses, both drought-resistant, would be
planted alongside wheat, which gave high yields in normal rains. They also
maintained livestock or, if forests were in the vicinity, gathered minor forest
produce. However, with the advent of green revolution and advent of electricity
and groundwater tube wells, the cropping patterns also changed. For example,
the farmers of Malwa (MP) used to grow jowar during the rains and Malwi Ghehu ,
a local wheat variety, after that till the advent of Green revolution. However,
once the pumps came in, farming became a year long activity. Cash crops like
soya displaced jowar. HYVs of wheat displaced Malwi Ghehu. This is the story of
almost all parts of India, and that is the reason that cotton, maize and soya
remain the major crops of the rainfed areas of India.
Issue 4: Groundwater level:
The too
much exploitation of the groundwater by tube wells led to the depletion of this
finite resource. For example, in some parts of Madhya Pradesh, the groundwater
levels have plunged from 50 ft in the 1970s to 700 ft now. Today, it has taken
a shape of acute crisis in six states of India. Note: If the ratio of
groundwater extraction to groundwater recharge is less than 70%, it is
considered safe; 70-90 %, semi critical; 90-100 %, critical; and more than
100%, overexploited. Between 1995 and 2004, the proportion of districts in
semi-critical, critical and over-exploited has grown from 5% of the
agricultural area and 7% of the population to 33% and 35% respectively.
The six states where the level of groundwater is unsustainable are Punjab,
Rajasthan, Haryana, Tamil Nadu, Gujarat and Uttar Pradesh. Ironically, these
six states accounted for half the food-grain production in 2008-09.
National Rainfed Area Authority (NRAA):
It was
established in 2006 to give focussed attention to Rainfed areas of the country.
This advisory body formulated some common guidelines for the Watershed
Development Project and is in consultation with all the States for its
implementation
