Assessing the Adoption of Drought-Tolerant Maize Genotypes as a Climate Adaptation Measure in Northern Ghana

Abstract

The study examines the adoption of drought-tolerant maize (DTM) as a climate adaptation measure among smallholder farmers in northern Ghana, using data from 500 households and probit model analysis to determine key adoption drivers. The findings reveal that only 28% of the sampled farmers have adopted DTM, with maize yield, awareness of DTM, access to extension services, and geographical location being significant influencing factors. Among these, maize yield and awareness of DTM have the strongest association with adoption decisions. Additionally, 29% of smallholder farmers employ early planting as a climate adaptation measure. Seed sourcing patterns show that 66% rely on saved seeds, while 33% obtain seeds from input dealers. Encouragingly, 96% of farmers expressed willingness to adopt improved maize varieties. Despite the relatively low adoption rate, targeted policy interventions, such as strengthening agricultural extension services, promoting climate-smart practices, and ensuring continuous research on DTM varieties, can enhance adoption and improve farmers’ resilience to climate change. These findings provide crucial insights for policymakers and agricultural stakeholders aiming to promote sustainable maize production in northern Ghana.
