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
![Page 25: Climate change V&A research at TERI: methods, experiences, and future possibilities](https://reader031.fdocuments.us/reader031/viewer/2022013106/56815592550346895dc36b77/html5/thumbnails/25.jpg)
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
![Page 26: Climate change V&A research at TERI: methods, experiences, and future possibilities](https://reader031.fdocuments.us/reader031/viewer/2022013106/56815592550346895dc36b77/html5/thumbnails/26.jpg)
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
![Page 27: Climate change V&A research at TERI: methods, experiences, and future possibilities](https://reader031.fdocuments.us/reader031/viewer/2022013106/56815592550346895dc36b77/html5/thumbnails/27.jpg)
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
