Understanding Barriers to Farmer Uptake of Rhizobia Inoculants for Non-Soybean Legumes in Sub-Saharan Africa
Introduction Nitrogen is a key driver of soil fertility, but many (SSPs) face depleted soils and high synthetic nitrogen fertilizer costs. Biological nitrogen fixation enables soil bacteria living in legume nodules to convert atmospheric nitrogen into plant-available forms, reducing reliance on synthetic inputs. Inoculation with symbiotic nitrogen-fixing bacteria (primarily Rhizobium and Bradyrhizobium spp.) is now…

Ag GeoSpatial Data Explorer (AgGeo): A Web-Based Tool for exploring Agricultural, Geospatial, and Climate Data
In 2023, approximately 282 million people across 59 countries faced severe food insecurity, an increase of 24 million from the previous year. Sub-Saharan Africa (SSA) bears a disproportionate burden of this crisis. Climate change is already reducing cereal production across the region, with projections showing a further 20% decline by 2030. Food import bills in…

How Well Does Machine Learning Predict Food Insufficiency? A Case Study from Malawi
The World Food Programme estimates (pdf) that approximately 3.5 million Malawians are chronically food insecure. That number rises, and hunger becomes more acute, in the lean season between harvests. Seasonal hunger is further aggravated by limited storage options and extreme weather events, such as the recent weak rains that rendered 25% of the population acutely…
