D
rought
is an insidious natural hazard with far-reaching impacts that range from
economic losses to losses in agriculture and livelihoods.
Meteorologically, ± 19% deviation of rainfall from the long-term mean is
considered ‘normal’ in India. Deficiency in the range 20 – 59%
represents ‘moderate’ drought and more than 60% is ‘severe’ drought.
Drought can cause or exacerbate water, food and national security
hazards. Rainfall, temperature, evaporation, vegetation health, soil
moisture, stream flow etc. are some of the critical parameters/indices
that are used in drought risk analysis.
Due to high temporal and spatial variability in
rainfall and wide variations in physiographic and climatic conditions in
the country, droughts are experienced in varying intensities (moderate
or severe) almost every year irrespective of a good monsoon. Since 2001,
India has experienced three major droughts in the years 2002, 2004 and
2009, severely affecting various sectors and the overall economic
development of the country.
Drought Management Strategies in India
Drought early
warning and monitoring are crucial components of drought preparedness
and mitigation plans. They are usually carried out using drought
indicators that are continuous functions of hydro meteorological
variables such as rainfall, vegetation activity, soil moisture
availability, etc. The success of drought preparedness and mitigation
depends to a large extent upon timely information about drought onset,
progress and areal extent.
Preventive
measures for drought mitigation
•
Dams/reservoirs and wetlands to store water
• Watershed
management
• Water
rationing
• Cattle
management
• Proper
selection of crops for drought-affected areas
•
Soil-conservation techniques
• Reducing
deforestation and fire-wood cutting in the affected areas
• Alternative
land-use models for water sustainability
• Checking of
migration and providing alternate employment
• Education
and training of the local people
•
Participatory community programmes
Preparedness
plan for drought management
• Improvement
in agriculture through modifying cropping patterns and introducing
drought-resistant varieties of crops.
• Management
of rangeland with improvement of grazing patterns.
•
Introduction of feed and protection of shrubs and trees.
• Development
of improved storage facilities, protection of surface water from
evaporation and introduction of drip irrigation system.
• Animal
husbandry activities can help in mitigation with use of improved and
scientific methods.
Drought management - way forward
While India has strong drought assessment
capabilities, there is need to enhance capacity for early warning and
impact monitoring, particularly in light of climate change impacts,
which can further compound the challenge of drought monitoring for early
warnings because of wide variability in rainfall pattern even at local
levels.
Regional
Level
1.
Enhancement of real time monitoring capabilities at a regional level
through training and joint monitoring programmes.
2.
Improvement in methodologies and analytical tools for drought analysis
and vulnerability assessment at the local and regional level.
3.
Organisation of joint training programmes to build human capacity in
improved resilience towards drought.
4. Effective
and collaborative implementation of drought relief programmes.
5.
Strengthening effective water and commodities supply system.
6. Capacity
of all stakeholders at different levels and especially PRIs and ULBs
should be enhanced for development of locally relevant climate resilient
plans addressing both adaptation and mitigation needs. Fiscal devolution
is critical to empower PRIs. Hence, the plans need to look at efficient
delivery mechanisms at all levels for access and utilisation of funds.
National
Level
1. Further
strengthening of the observational network for drought monitoring to
bridge the gap between the existing and desired meteorological and
hydrological monitoring network.
2.
Improvement in information and communication technologies in an
integrated manner for tackling the multifaceted challenge of drought at
various spatial scales.
3. Capacity
enhancement for medium and long range drought forecasting.
4. Better
coordination among ministries and departments.
5. Developing
mechanism for context specific and need based forecasting including
local language for better understanding.
6. Developing
comprehensive tools for integrated drought management and reservoir
operation during drought periods based on various drought climate
scenarios and water saving actions.
Development Alternatives’ Strategies for Drought
Management in Bundelkhand
The below mentioned programmes are a combination of
both institutional and technological innovations that aim to mainstream
participatory planning for collective management of natural resources,
climate change and drought in one of India’s most climate sensitive and
drought prone regions. The lessons learnt from Development Alternatives’
experiences of drought management in Bundelkhand can be used in other
drought prone areas of the country.
Watershed management
Through integrated soil and water conservation
programmes over the last 30 years, Development Alternatives has
rejuvenated more than 30,000 hectares of land in Bundelkhand, an
extremely drought prone region in Central India. Construction of more
than 250 water harvesting structures such as check dams, farm ponds,
gabions, counter trenches have helped increase groundwater level in this
drought prone region.
Climate resilient agriculture
Agriculture is the foundation of the rural economy of
Bundelkhand, with 90% of the population being dependent on agriculture
as their primary livelihood. However, agricultural systems in
Bundelkhand are largely rain-fed and therefore vulnerable to climate
change impacts. Such impacts are adversely impacting hydrology, soil
conditions and ecosystem services consequently resulting in declining
agri-productivity and livelihood stress.
Development Alternatives has been advocating smart
agricultural practices in the region and supporting almost 30,000
farming communities by delivering complete package of practices for
drought resistant and low water requirement crops.
Agro-Forestry
Agro-forestry models i.e. the growing of seasonal
crops along with perennial trees have been demonstrated on farmers’
fields to promote awareness on the ability of such models to restore
soil heath and productivity, improve water recharge and reduce soil
erosion losses. Development Alternatives is currently working with
almost 20,000 tribal communities in the region to promote this
sustainable model. Economically important species and varieties adapted
to local soil and weather conditions such as Teak, Gulmohar, Shisham,
Bamboo etc. and fruit species such as Gooseberry (Amla), Guava,
Lemon, Karaunda, Custard Apple, Indian Plum (Ber) and
Jackfruit have been planted so that there is wide species diversity on
the farms. The practice of agro-forestry has enhanced livelihood
security through the creation of multiple revenue streams for the
farmers, aided nutrition security of the farmers’ households and also
created ecological niches that have allowed the conservation and
regeneration of local biodiversity.
