Abstract

This paper provides new cross-country evidence that greater investment in agricultural R&D significantly mitigates the adverse effects of climate variability on crop yields in sub-Saharan Africa. Despite this critical role, only a handful of countries have invested at levels sufficient to reach the thresholds where R&D delivers effective risk adaptation. Our analysis indicates that closing this gap would require an additional US$1–3 billion in annual agricultural research investment across the region.
