Agricultural production in sub-Saharan Africa has, in recent times, remained lower than the rest of the world. Many attribute this to factors inherent to Africa and its people, such as climate, soil quality, slavery and disease. This article traces the role of agriculture through history and argues that these are not the main reasons. Before the arrival of European traders, complex agricultural systems existed, which supported food security, manufacturing and trade. External interference manipulated these systems in pursuit of export crops. Independence has not fundamentally changed this; resource and wealth extraction continue to inhibit economic development for Africans in Africa.

This article explores the factors causing the current poor performance of most government irrigation schemes in sub-Saharan Africa. The literature review finds that the poor performance is not primarily caused by socioeconomic and biophysical conditions inherent to sub-Saharan Africa. African farmers have adapted to diverse biophysical conditions and expanded or contracted their area under agricultural water management in response to market signals. Rather, this poor performance is predominantly linked to the production systems introduced during colonialism and developments since independence, such as agricultural policies restraining rural economic development, unsuitable irrigation technologies and agricultural practices, and international lending practices and trade arrangements.

This article is the third in a series of historical reviews on sub-Saharan Africa (SSA), exploring why agricultural production and irrigation schemes are underperforming, and how this contributes to high levels of food insecurity. The expression ‘food security’ emerged in 1974 following the Sahel and Darfur famines. Despite SSA being a net agricultural exporter, food insecurity has persisted and is increasing. This is largely a legacy of the export-oriented colonial agricultural production systems, which procured scarce fertile land, water and labour to meet the needs of industries and consumers in the Global North. Colonialism also undermined the social contract between traditional leaders and communities, which had been instrumental in managing food scarcity in earlier times. Post-independence, agricultural policies remained focused on exports and neglected critical research and investment: integrating food productions systems into the domestic economy; developing supply chains and associated market, storage and value-adding infrastructure; and introducing appropriate technologies. As a result, Africa is the only region in the world where increased export production caused a decline in per capita food production. African nations should be extracted from the debt accrued due to poor colonial investments, World Bank lending practices, and global currency and interest fluctuations, which have crippled their capacity to support agriculture and improve livelihoods and food security. Farming needs to be profitable, which includes farmers being connected to domestic supply chains and market signals, local value-adding, and post-harvest storage. This will create jobs and increase income earning capacity, which is the key to households’ food security.

The United Nations calls for action to achieve 17 sustainable development goals (SDGs). We argue that the current development paradigm is an impediment to achieving several of these goals. We identify 14 agricultural research and development (R&D) needs, which ought to be addressed to achieve critical SDGs. We also identify the paradigm shifts required, particularly from global and international organizations, to facilitate this R&D and implement its outcomes. Importantly, the Global North2 would have to divert its focus from securing access to cheap land, water and labour that is primarily used to generate agricultural exports and business opportunities for Global North investors. Instead, the focus needs to be on creating opportunities for local farming communities to produce food for domestic markets, increase income and generate local jobs and business opportunities. Circular food systems can support a range of SDG goals, such as no hunger and zero poverty and slow migration, especially of youth, to big cities or foreign lands with insecure jobs.
