The fire severity of the 2013–2014 fire season within Sudanian ecosystems in Burkina Faso was evaluated from Landsat 8 images using derivatives of the Normalized Burn Ratio algorithm (NBR). The relationship between the image-derived severity and the field observed severity i.e. Composite Burn Index (CBI) was best described by a nonlinear model of the form y = a + b*EXP(CBI *c) (R2 = 0.66). Classification of the image-derived burned area into burn severity classes achieved a classification Kappa accuracy statistic of 0.56.

Evaluating the relationships between property rights, risk technology and productivity in sub-Saharan Africa

The vulnerability of Africa’s agriculture to climate change is complex. It is shaped by biophysical, economic, socio-cultural, geographical, ecological, institutional, technological and governance processes that interact in intricate ways, and can together reduce farmers’ adaptive capacity. Women farmers with few resources are particularly vulnerable. This working paper highlights the array of adaptation strategies that exist across Africa’s diverse farming systems and climatic conditions. These strategies can provide the impetus for transforming Africa’s agriculture.
