Increased Rice Yield Improves Nutrition of Farmers in Madagascar
―Towards solving malnutrition problem in Africa by improving productivity of staple crops

Main Points

  • Increased yield of rice, the main staple food in Madagascar, is effective in increasing the supply of energy and micronutrients to farmers in rural Madagascar.
  • Increased yield is associated not only with higher rice consumption, but also increased household cash revenue for purchase of nutritious food groups.
  • Increased productivity of staple food crops is expected to contribute to SDG 2: Zero Hunger

Overview

JIRCAS, in collaboration with the University of Tokyo and the National Office of Nutrition of Madagascar, has used econometric methods to show that increasing the yield of rice, the main staple food in Madagascar, is effective in improving farmers' nutrition in rural areas where serious nutrition problems exist.

The analysis in this study showed that increased rice yield resulted not only in increased rice consumption but also in increased purchase of nutritious foods such as vegetables, fruits, and meat/fish due to the cash income from rice sales. It was suggested that the diversification of foods consumed through these purchase behaviors contributes to improved nutrition, not only in terms of energy supply, but also in terms of the supply of micronutrients such as vitamin A, zinc and iron, i.e., in both quantity and quality.

Until now, there have been limited studies evaluating the impact of increased productivity of staple food crops on farmers' nutritional supply in rural areas of sub-Saharan Africa. This study found that technological interventions to improve paddy rice productivity can lead to diversification of purchasing behavior through consumption and markets, leading to improved nutrition for poor farmers, and is expected to contribute to Goal 2 of the Sustainable Development Goals (SDGs), "Zero Hunger".

The results of this research have been published in the electronic edition of Food Security, an international scientific journal, on January 11, 2023 (JST).
