“…Many of these components have antioxidant properties, and a clear correlation between antioxidant properties and colour of the seed coat has been demonstrated (e.g., in cowpea seed coat [ 69 , 70 ]). Adedayo et al [ 71 ] found that the more colourful seeds of Vigna subterranea have greater antioxidant capacity. In Phaseolus vulgaris, antioxidant capacity is higher in beans with dark seed coats, in which phenolic compounds and flavonoids were found in higher quantities [ 72 ].…”

Cashew is an important export-oriented crop in several tropical countries, often under monocropping systems. Intercropping with legume species is promoted as a sustainable practice, enhancing agricultural productivity and providing nutritional food sources to rural communities. This study aimed to characterize the diversity of Leguminosae (or Fabaceae) in the cashew agroforestry systems of East Timor (Southeast Asia). Fourteen cashew orchards were sampled across the country, and information about leguminous species uses was collected from local populations. About 50 species are commonly part of the country’s cashew agroforestry system, many of them simultaneously used as food, fodder, and in traditional medicine. Six bean species—Cajanus cajan (L.) Huth, Phaseolus lunatus L., Phaseolus vulgaris L., Vigna angularis (Willd.) Ohwi and H.Ohashi, Vigna radiata (L.) R.Wilczek and Vigna unguiculata (L.) Walp.—are largely used as food. The mineral contents of these beans revealed relevant differences between species and, in some cases, between types (seed colour) within species. Periods of hunger and low food variety are frequent in East Timor, reflecting a very poor nutritional state of the population. Knowing and using legumes for local nutrition, as well as for healthcare and well-being, adds great value to these species as components of East Timor cashew agroforestry systems.

“…Significant levels of alkaloids, flavonoid conjugates (including epicatechin, catechin, [21] quercetin, kaempferol, apigenin, glycosides), saponins, steroids, triterpenoids, phenols, anthocyanins and carotenoids have also been reported [22,23,24]. The highest concentration of tannins and flavonoids have been found in red and brown V. subterranean.…”

The global effort in fighting the nutrition war seems to be witnessing a record setback owing to recent climatic changes, growing insecurity, COVID-19 disruptions etc. all resulting in a global rise in food prices. Parts of Africa and Asia have constantly ranked high in the Global Hunger Index (GHI) and are already associated with the poverty and malnutrition crisis. Women and children remain the worst victims of this crisis. Although Africa is a host to a number of locally sourced, nutritious food crops which have been used as food in the time past, these crops remain underutilized while Sub-Sahara Africa remains on the red list for malnutrition. Among these underutilized plants is Bambara groundnut (Vigna subterranean (L.) Verdc, synonym; Voandzeia subterranean (L.) Thouars. The seeds contain about 64.4% carbohydrate, 23.6% protein, 6.5% fat, 5.5% fiber and a lot of minerals as well as a number of secondary metabolites. In Africa, the nuts have been processed into various meals which are cheaper sources of protein with high acceptability. Bambara nuts, with such a rich nutritional content can be cultivated even in the arid and semi-arid regions of the world which are ravaged by malnutrition. Highlighting and promoting such cheaper, highly nutritious foods, can be a very effective weapon for dealing with the current malnutrition crisis in the world. With this, the global sustainable development goals #2 and #3, already grossly set back by COVID-19 and global insecurity etc., may still be attainable by the year 2030.

“…Bambara groundnut plays an important role not only in addressing food and nutritional well-being, but also in boosting immunity ( Adebowale et al, 2011 ; Adedayo et al, 2021 ), livestock feed ( Feldman et al, 2019 ), improving biodiversity, and protecting farmers’ livelihoods. Resistant starch is concentrated in this crop, which encourages the slow and sustained release of glucose into the bloodstream, making a healthy diet ( Cummings and Englyst, 1995 ).…”

Breeding Potentials of Bambara Groundnut for Food and Nutrition Security in the Face of Climate Change

Constant production of quality food should be a norm in any community, but climate change, increasing population, and unavailability of land for farming affect food production. As a result, food scarcity is affecting some communities, especially in the developing world. Finding a stable solution to this problem is a major cause of concern for researchers. Synergistic application of molecular marker techniques with next generation sequencing (NGS) technologies can unlock the potentials hidden in most crop genomes for improving yield and food availability. Most crops such as Bambara groundnut (BGN), Winged bean, and African yam bean are underutilized. These underutilized crops can compete with the major crops such as cowpea, soybean, maize, and rice, in areas of nutrition, ability to withstand drought stress, economic importance, and food production. One of these underutilized crops, BGN [Vigna subterranea (L.), Verdc.], is an indigenous African legume and can survive in tropical climates and marginal soils. In this review, we focus on the roles of BGN and the opportunities it possesses in tackling food insecurity and its benefits to local farmers. We will discuss BGN’s potential impact on global food production and how the advances in NGS technologies can enhance its production.
