Community Based Adaptation (CBA) embodies local community action on climate adaptation initiatives. This may involve participatory learning and problem-solving (including creative trial-and-error approaches), documentation and sharing, collaborative planning and local implementation of climate adaptation initiatives.

Some examples of Community Based Adaptation may be local adaptive planning around changing rainy seasons with modified agricultural planting seasons as well as adjusted crop choice, sometimes termed climate-smart food production; community disaster risk trainings to store water and food stuffs on high-and-dry lands to cope with increase of floods; local redesign of building structures to mitigate losses from high-intensity cyclones, floods, or soil erosion; community cooperation on mangrove and native biodiversity restoration, increasing resilience to coastal erosion while creating local sustainable livelihoods.

CBA can be locally derived or managed, reflective of local cultures / eco-cultures / bio-cultures (perceptions of, and relationships to, humans and non-humans and nature) and societal functions. This offers an opportunity for sustainable and sustaining, self-organising and evolving local engagement on climate change adaptation, guided by local knowledge and wisdom, including Indigenous and other forms of traditional ecological knowledge (TEK) relating to adaptive management of complex social-ecologies of specific populations. 

This CBA Theme spaces also opens consideration of 'local' community based climate action within local-to-local network engagement of climate iniatives wherein the diversity and local endogeneity remains, yet is enhanced through wider network collaboration and sharing.

Above is an example of community developed climate-smart agriculture collaboratively evolved across a network of local farmers in a Karen village bordering Myanmar and Thailand. CBA approaches include a merging of organic techniques with traditional ecological knowledge for adaptive management. Farmers interspersed trees and other plants to help mitigate against landslides becoming more common in these hills, with higher temperatures, protracted drought and fires, followed by heavy rainfall.
