Briefings

Scientists analyzed 50 years of climate and soil data to identify optimal planting times for bambara groundnuts in Southern Africa. Their model determined that planting in October, coinciding with the onset of the rainy season, yields the highest production, while later sowing risks frost and reduced yields. This research aims to diversify food security by promoting indigenous crops that are drought-tolerant and nutrient-rich, addressing challenges in rain-fed maize production.

Key points

• A 50-year climate and soil data simulation identified October as the optimal planting time for bambara groundnuts in Southern Africa, producing highest yields.
• Planting later in the year risks frost and yield reductions, whereas October planting aligns with the onset of the rainy season.

Context

Southern Africa faces food security challenges due to water stress and climate change, making rain-fed maize production difficult. Indigenous crops like bambara groundnuts offer drought tolerance and high nutritional value, but farmers lack planting guidance. The study uses the Food and Agriculture Organization AquaCrop model to provide this critical information.

Limitations

The study covers 5,838 altitude zones across South Africa, Lesotho, and Eswatini using 50 years of data. It does not account for future climate change scenarios beyond the historical period, and specific local microclimates within the study area were not fully detailed.
