Drought-resistant sorghum varieties have been introduced to smallholder farmers in northern Ghana to mitigate the effects of climate change and improve agricultural productivity. A systematic search strategy was employed across multiple databases to identify relevant studies. Studies published between and were included for analysis. The review identified a significant proportion (78%) of farmers adopting drought-resistant sorghum varieties, with notable variations in adoption rates based on geographic location and farmer education level. Adoption mechanisms vary significantly among different groups of smallholder farmers, necessitating tailored strategies for effective dissemination and uptake. Policy makers should invest in targeted agricultural extension programmes to enhance the adoption rate of drought-resistant sorghum varieties by improving access to seeds, knowledge, and resources.
