Addressing the linkages between climate change and vulnerability to food insecurity Testing a methodology in Nicaragua Jeronim Capaldo – Agricultural Economics Division (ESA) Anna Ricoy - Climate, Energy and Tenure Division (NRC)

Purpose, rationale and approach Purpose To contribute to a comprehensive research approach that bridges the gap between analysis of climate change (CC) impacts on food security (FS) and policy-making Rationale Downscale the broad and global CC agenda at the local level Engage policy makers to better address the impact of CC on FS at household level Approach Focus on vulnerable groups Address the access component of FS

Key analytical questions How does CC affect access to food at household level? How does household vulnerability to food insecurity evolve as a result of CC? How will vulnerability be distributed as a result of CC? What policy instruments to increase the resilience of vulnerable groups to deal with the impact of CC on FS? How to improve the design and targeting of policy responses to address the impacts of CC on vulnerable groups?

1 - Downscaling of CC scenarios Generation of high-resolution climate change projections using RCMs (PRECIS, Hadley Center) Under ECHAM4, for A2 scenario  CC scenarios to a 50x50km scale for the whole Nicaragua, at “municipio” level  Time series of estimated temperature and precipitation projections to the 2030 horizon coordinates of the PRECIS grid Change Temperature (Annual mean) –2080s

2 - Analysis of vulnerability to food insecurity Quantitative analysis of the livelihood effect of CC: -building on the notion of vulnerability to food insecurity -using an analytical model developed by ESA based on rural national household datasets CC enters the model through the impacts that temperature and precipitation changes have on income (value of land productivity) and food consumption (expenditure) Model allows characterizing vulnerability and identifying variables associated with highest levels of vulnerability  Profiling of vulnerable household groups

3 - Analysis of policy implications Purpose: to provide recommendations for improvements in the design and targeting of policy responses that address the impacts of CC on household FS Next steps, in-country: What instruments should be promoted to increase households’ ability to cope with the impacts of CC on FS and adapt to climate change? What are the policies, institutions and multi-level governance arrangements needed to support vulnerable households? Links to specific practices: synergies adaptation, mitigation,, FS Short + long-term policies addressing DRM/CCA measures tailored to vulnerable groups Integration of the linkages between CC and household FS within all the phases of the policy cycle Coherence between the local, national, regional level

Conclusions on the analysis of vulnerability to food insecurity Model contributes to improved program design and preparedness planning by: –Making distinction between transitory and chronically food insecure households –Estimating impact of shocks (e.g. climate) on household vulnerability and number of affected households –Profiling the vulnerable

Lessons learned matching data to geographical locations with GIS biophysical impacts on crop production Estimation of vulnerability with climate data requires non-linear models Estimation of probability How can the assessment be improved?

Moving forward Nicaragua is a pilot. Lessons learned will serve to improve the methodology Replication envisaged in different institutional and policy contexts Ultimate goal is to develop a robust research framework on the impacts of CC on household FS and related policy-level implications
