Jhalawar, Rajasthan • drought prone• low irrigation coverage, literacy, infrastructure

Chitradurga, Karnataka• water scarcity• proximity to city• contract farming and exports

Anantapur, Andhra Pradesh• semi-arid • response of groundnut farmers to import competition

Jagatsingpur, Orissa• cyclones, river floods (loss of mangroves)• high population density• acute poverty• proximity to port

Raipur, Chattisgarh• rice belt of central India• crop diversification• low literacy, infrastructure

Understanding vulnerability:

Local and community focus

A tale of two villages

Lakhakheri Umat: rainfed farming onlySemi/medium farmers – sale of stocksLandless labourers – seasonal migrationSmall/marginal farmers – temporary

coping measuresNo long-term adaptive solutions

Anghora: head-end of damAccess to irrigation opens up range of

coping optionsMuch better availability of electricity,

health facilities, and transport infrastructure (Kota markets)

Addressing vulnerability

Incorporating adaptation thinking in policymaking: some examples

Incentives for making existing schemes available to small/marginal farmers– Credit, insurance, subsidies, HYVs

Cross-sectoral dialogue– Tail-end villages in command area

Agri-based industries and markets– Rice mills, purchase ceilings, Nagari-dhuvraj, jute mills

Support for traditional options– Teevra crop on residual soil moisture, fruits and vegetables in

homestead Development is the best form of adaptation

– Education, health facilities, electricity, roads

Developing adaptation efforts

Effective adaptation strategies require understanding of regional / local dimensions of vulnerability

Climate change does not occur in isolation – multiple stresses

Domestic policies can enhance or constrain farmers’ ability to adapt to climate change

Adapting to climate variability and climate change Adaptation and sustainable development policies

Future research directions

• Further exploration of multi-tiered research approach – Multiple climate scenarios, extreme events– Application to other sectors / specific regions– Econometric modelling of determinants of

vulnerability

• Focus on policy aspects at level of state departments (including cross-sectoral issues)

• Capacity building and demonstration of adaptation options
