Local perturbations such as terrain, land cover, and land-water boundary often exert a strong influence on the local climate and create eco-climatic structures or complexes that can support the natural resource capita on which livelihoods depend. This research focuses on the eco-climatic complexes that produce the natural resource capita which supports livelihood systems across the wooded savannah of western Nigeria. Downscaled climate data can be integrated and analyzed with the drivers of the local climate system, enabling their spatial pattern of influence and impact on the local climate system to be deciphered and quantified so that it becomes useful
