Knowledge of non-linear and variable climate risks generated by the interaction between climate and terrestrial ecosystems at local spatial scales is important for place-based and context specific adaptation. In this study we generated 24 risk factors from 9 climate risk determinants based on the trend in present and future climate, water footprints associated with climate–ecogeographic interactions, climate–land cover relations and socio-demographic profiles. The description of aggregate climate risk was compared across community clusters, local government areas, and 3 broad zones in the wooded savannah of Nigeria. The results suggest rainfall, which is increasing at about 0.6 mm/decade under the present climate will decline by about 4 mm/decade under future climate. Future maximum temperature is projected to increase by about 0.02 °C/decade, a rate that is lower than the present 0.06 °C/decade. Rainfall …
