ABSTRACT

This paper proposes a GIS-based framework for mapping climatic conditions relevant to agriculture in the Congo River Basin, where sparse in situ observations and strong convective variability complicate agroclimatic assessment. We discuss key challenges (data gaps, product inconsistencies, validation constraints and scale effects) and outline a multi-source workflow that harmonizes air temperature, precipitation and derived agroclimatic indicators to a common baseline (1991–2020). The approach combines satellite precipitation estimates, analysis products and high-resolution climatologies; uncertainty is quantified through inter-product comparison and cross-validation against available stations. Using Köppen–Geiger classes, aridity and rainfall seasonality metrics, we delineate major agroclimatic zones and identify hotspots of drought, excessive wetness and heat stress. The resulting map set, integrated with soils, terrain and settlement layers, provides an operational basis for climate-risk screening and subsequent natural-hazard mapping to support agricultural planning. Future work is linked to higher-frequency datasets, regional climate modeling and machine-learning downscaling to better represent local gradients and extremes.
