Extreme climate events already expose food systems to shocks and stresses, thus affecting food production and access to food of different groups. For this reason, it is becoming increasingly important to understand the complexity of factors and processes that constrain or enable people's ability to build resilient livelihoods. This includes their ability to access and control the resources needed to adapt to shockes and stresses and become food secure. This working paper presents a toolkit to be used to understandd the interrelations between climate impacts, food systems, and livelihood strategies at the local level. It applies a multidimensional view f vulnerability of livelihood strategies to climate change, with a focus on differentiated access and entitlements to livelihood resources and food for different groups within the community. The methodology has developed an ad hoc toolkit to support participatory vulnerability analyses in rural communities, and includes participatory tools that were adapted to answer why people are vulnerable, how they are vulnerable to climate change, and what are the consequences in relation to their food security. This toolkit has been designed for organizations or local governments that want to implement climate change adaptation and food security projects in rural localities.
