It is widely understood that the food insecurity crisis in the Sahel and the Horn of Africa is one of the world’s fastest growing and most neglected crises. It lacks sufficient global focus, resources and urgency. As in so many crises, women and girls are disproportionately affected and shoulder the consequences of protracted neglect, with unconscionable impacts on their safety, life chances and agency. Gaining a holistic view of the gendered drivers, risks and impacts of food insecurity in the Sahel and the Horn of Africa is difficult. This is due to a lack of data and prioritization, and the large geographical and socioeconomic terrain covered by both regions. However, what we do know about this crisis is more than enough to urgently address the needs of women and girls. An OCHA discussion paper on this topic (which will be published imminently, and from which this policy brief is drawn) found that there is: A strong risk of profound regression in gender equality gains made to date in the countries of concern, including on education, sexual and reproductive health, and the economic independence of women and girls (with knock-on effects on broader humanitarian and development outcomes). An increasing challenge to reverse what must be recognized as a protracted and growing gender-based violence (GBV) emergency in the Sahel and the Horn of Africa. The food insecurity crisis in the Sahel and the Horn of Africa is protracted, multidimensional and highly gendered, with spiralling impacts on gender equality and food security outcomes. It is driven by interwoven and overlapping factors, including climate change, political instability, conflict, socioeconomic conditions, migration and displacement and, more recently, COVID-19 and the war in Ukraine. Interlinked with these factors are gendered structural drivers of food insecurity, including deeply entrenched gender inequalities and harmful social norms. Gendered risks and impacts of food insecurity include alarming limitations on access to education, sexual and reproductive health rights, women’s agency and participation, and dramatic increases in different existing forms of GBV and the emergence of new ones. Recognition of such gendered dimensions of food insecurity and of the need for a multisectoral approach in the response is key to addressing the crisis, along-side sustained commitment and adequate allocation of resources. This policy brief draws out key findings from the OCHA discussion paper on this topic, which includes a desk review of studies, assessments and reports, and interviews with local women’s organizations on the front lines of the food insecurity crisis in communities across both regions. Below are the most pressing gendered drivers, risks and impacts of food insecurity (not in order of priority), as well as key gaps in the current humanitarian response to food insecurity, and recommendations to take forward.
