A review in the journal Frontiers examines how digital technologies can support climate-smart agriculture in Sub-Saharan Africa, where smallholder systems face rising temperatures, erratic rainfall and persistent yield gaps.

The study surveys tools across several categories: remote sensing and satellite imagery for monitoring crops and land condition, precision agriculture inputs such as variable-rate application, mobile-based advisory services that deliver weather and agronomic information to farmers, and data platforms that integrate climate information into farm planning.

According to the review, these technologies can improve adaptation and resilience by helping farmers time planting decisions, manage water more efficiently, and respond to pests and weather shocks. Mobile services in particular have expanded access to information in regions where extension systems are thin.

The authors also flag constraints. Connectivity gaps, limited digital literacy, the cost of devices and data, and weak institutional support can restrict adoption among smallholders. They argue that scaling requires investment in rural infrastructure, farmer training and policies that make tools affordable and locally relevant.

The review concludes that digital innovation can meaningfully strengthen climate adaptation in Sub-Saharan African agriculture if deployment addresses these barriers alongside the technology itself.
