This chapter reviews food security in the West African Sahel, exploring the question of why, since the great drought-famines, of the late 1960s and early 1970s, food security and vulnerability to both climatic and market perturbations have not substantially improved and in some respects has deteriorated. Using my book Silent Violence, which was published in 1983, I revisit and review theories of famine and food security as they have been developed in and around African development. Using a village study in northern Nigeria, I argue that the precariousness of rural life can be explained by the shifting political economy of Nigeria and the forms of rural differentiation and inequality associated with, in the Nigerian case, the emergence of oil as the economic backbone of the country. While Nigeria as a petrostate is a special case, the dynamics at work point to general conditions prevailing across the West African Sahel. Since the 1970s there have been important shifts in policy regarding food and famine, and the ruling orthodoxy is now building resilience through the combination of traditional adaptability and decentralized forms of market integration. I investigate the origins and consequences of this approach and whether it can address the looming problems of global climate change.

Abstract The West African Sahel has been facing for more than 30 years an increase in extreme rainfalls with strong socio-economic impacts. This situation challenges decision-makers to define adaptation strategies in a rapidly changing climate. The present study proposes (i) a quantitative characterization of the trends in extreme rainfalls at the regional scale, (ii) the translation of the trends into metrics that can be used by hydrological risk managers, (iii) elements for understanding the link between the climatology of extreme and mean rainfall. Based on a regional non-stationary statistical model applied to in-situ daily rainfall data over the period 1983-2015, we show that the region-wide increasing trend in extreme rainfalls is highly significant. The change in extreme value distribution reflects an increase in both the mean and variability, producing a 5%/decade increase in extreme rainfall intensity whatever the return period. The statistical framework provides operational elements for revising the design methods of hydraulic structures which most often assume a stationary climate. Finally, the study shows that the increase in extreme rainfall is more attributable to an increase in the intensity of storms (80%) than to their occurrence (20%), reflecting a major disruption from the decadal variability of the rainfall regime documented in the region since 1950.
