Investments in agricultural research in sub-Saharan Africa lead to high payoffs in terms of reduced poverty and increased productivity.<\/figcaption><\/figure><\/p>\n\n\n\n

A study on the impact of agricultural research on productivity and poverty in sub-Saharan Africa (SSA) shows that agricultural research is reducing the number of poor people in the region by 2.3 million annually.<\/p>\n\n\n\n

The study, authored by Arega Alene and Ousmane Coulibaly of the International Institute of Tropical Agriculture (IITA), finds that the estimated aggregate rate of return from agricultural research runs as high as 55%.<\/p>\n\n\n\n

However, the researchers\u00a0add that the actual impacts are not large enough to offset the poverty-increasing effects of population growth and environmental degradation in the region.<\/p>\n\n\n\n

The study, which has been published in the Food Policy Journal, further demonstrates that doubling investments in agricultural research and development in SSA from the current US$650 million could reduce poverty by two percentage points\u00a0every year.<\/p>\n\n\n\n

\u201cHowever, this would not be realized without more efficient extension, credit, and input supply systems,\u201d says Alene.<\/p>\n\n\n\n

The researchers also established that agricultural research had contributed significantly to productivity growth in SSA.<\/p>\n\n\n\n

Highest payoffs to agricultural research were found in Ghana, Cameroon, Nigeria and Ethiopia, and were attributable to sustained national research investments with modest research capacity, long-term CGIAR operations, and regional technology spillovers.<\/p>\n\n\n\n

International agricultural research by the CGIAR contributed about 56% of the total poverty reduction impact in the region. According to the study, in view of the significant long-term research investments and demonstrated successes in SSA, the reduction in poverty attributed to IITA’s research within the CGIAR ranges from 500,000 to one million poor people per year.<\/p>\n\n\n\n

Despite the contribution of agricultural research and development, the study notes that SSA also faces several constraints outside the research system that hinder the realization of potential research benefits. The study singled out weak extension systems, lack of efficient credit and input supply systems, and poor infrastructure development.<\/p>\n\n\n\n

The study concludes that efforts aimed at improving the functioning of extension, credit, and input supply systems could significantly contribute to reducing poverty even more when coupled with effective agricultural research.<\/p>\n\n\n\n

<\/strong>L'Afrique est confront\u00e9e \u00e0 des probl\u00e8mes complexes qui minent l'agriculture et la vie des populations. Nous d\u00e9veloppons des solutions agricoles avec nos partenaires pour lutter contre la faim et la pauvret\u00e9. Nos recherches pour le d\u00e9veloppement (R4D), maintes fois r\u00e9compens\u00e9es, reposent sur une r\u00e9flexion cibl\u00e9e et autoris\u00e9e, ancr\u00e9e dans les besoins de d\u00e9veloppement de l'Afrique subsaharienne. Nous travaillons avec des partenaires en Afrique et au-del\u00e0 pour r\u00e9duire les risques pour les producteurs et les consommateurs, am\u00e9liorer la qualit\u00e9 et la productivit\u00e9 des cultures, et g\u00e9n\u00e9rer de la richesse gr\u00e2ce \u00e0 l'agriculture.
