Agricultural diversification: the potential for underutilised crops in Africa's changing climates

Area of Science:

• Agricultural Science
• Climate Change Adaptation
• Food Security Studies

Background:

• Climate change and declining agricultural diversity pose significant threats to global food security and nutrition.
• Africa, a center of agricultural biodiversity, faces substantial climate change impacts on crop production.
• The Green Revolution's limited success in tropical environments highlights the need for alternative strategies.

Purpose of the Study:

• To examine the interconnectedness of climate change and crop diversity impacts on global food security.
• To reassess the Green Revolution's effectiveness in diverse agroecological zones, particularly in Africa.
• To advocate for the utilization of indigenous, underutilized crops as a complementary strategy for future food systems.

Main Methods:

• Literature review and analysis of climate change and agricultural diversity impacts.
• Case study approach focusing on multidisciplinary research of bambara groundnut (Vigna subterranea).
• Examination of traditional farming systems and the role of local communities in crop conservation.

Main Results:

• Climate change and reduced crop diversity are intrinsically linked, with significant implications for food security.
• Indigenous crops, like bambara groundnut, represent a vast, underutilized resource for climate-resilient agriculture.
• Multidisciplinary research on bambara groundnut demonstrates its potential for cultivation and utilization in sub-Saharan Africa.

Conclusions:

• A shift towards harnessing indigenous and underutilized crops is crucial for enhancing global food security in the face of climate change.
• The bambara groundnut case study provides a model for developing other neglected crops for future food systems.
• Integrating traditional knowledge with scientific research can unlock the potential of diverse agroecosystems for sustainable food production.
