Legumes in Sub-Saharan Africa (SSA)

Source: Piyaset

Legumes are versatile crops with lots of uses from a source of food to providing income, being animal feed and some legume varieties are used as medicine and fuel (Muoni et al., 2019, Akpalu et al., 2013).

Legumes have a good chance to enhance food and nutrition security in SSA because they are related to the local community’s culture and food consumption patterns. Legumes are nutritious and are able to adapt to rough climatic conditions and poor marginal soils (Abberton et al., 2022).

Legumes available and cultivated in SSA include African yam bean, bambara groundnut, cowpea, groundnuts, soybean, chickpea, pigeon pea (Stanton et al., 1966). African yam bean and bambara are part of the unpopular indigenous under-utilized orphan legumes including Kersting’s groundnut, Lima bean, and Jack bean (Popoola et al., 2022).

The inclusion of legumes in a diet could offer a lifelong solution to SSA malnutrition, hunger, and protein deficiencies because legumes are nutrient-dense, and provide great quality protein & micronutrients (Popoola et al., 2022).

Besides nutritional benefits, legumes also have environmental benefits such as enhancing soil moisture, and water effectiveness, covering the soil, reducing soil evaporation, fixing soil nitrogen, and controlling erosion and weed (Vidigal et al., 2019, Popoola et al., 2022)

Legume challenges include long cooking time, poor shelf-life, low yield, sensitivity to daylight, presence of potent anti-nutritional factors, these challenges have discouraged utilization and production because farmers are less interested in investing their time and energy in cultivating and producing legumes (Nnamani et al., 2017; Popoola et al., 2020, Popoola et al., 2022).

Other challenges include poor market price, poor demand, lack of buyers, lack of improved varieties, and inadequate capital that have hampered their production (Khan et al., 2021). To deal with these challenges and get benefits from legumes  Popoola et al. (2022) suggest that there is a necessity for systematic cultivation, wide acceptance, increased utilization, strategic crop improvement and funding, and the creation of global and local market spaces to improve consumption across the SSA.
