As climate change continues to disrupt Ghana’s agricultural systems, its effects are being felt most sharply by smallholder farmers who depend on predictable weather patterns for survival. Among them are mango farmers in the Yilo Krobo Municipality, whose experiences offer important lessons for Ghana’s climate resilience agenda.
Mango farming is increasingly becoming a strategic agribusiness in Ghana. Beyond local consumption, mango has export potential and provides income opportunities across the value chain- from production and processing to transport and trade. Yet, mango trees are highly vulnerable to climate stress. Irregular rainfall, prolonged dry seasons, rising temperatures, and pest outbreaks are now common threats.
A recent field-based study led by Dr. Kwaku Adu (Department of Applied Economics, University of Environment and Sustainable Development) among mango farmers in Yilo Krobo reveals how farmers are responding through Climate-Smart Agriculture (CSA) and why adoption remains uneven.
What Farmers Are Doing Right
The study shows that farmers are quick to adopt practices with immediate and visible benefits. Improved mango seedlings, proper spacing, pruning, and pesticide use are widely practiced. These methods directly improve yields and reduce losses, making them attractive to farmers operating with limited capital.
However, climate-smart practices that build long-term resilience, such as mulching, cover cropping, and water conservation, are far less common. These practices protect soil moisture, improve fertility, and reduce climate risks but they require additional labour, technical knowledge, and delayed returns.
Why Adoption Is Uneven
Several factors explain why some farmers adopt more climate-smart practices than others.
Education plays a critical role. Farmers with more years of schooling are better able to understand climate risks and appreciate the long-term benefits of sustainable practices. Similarly, farmers who have access to extension services are more likely to adopt climate-smart methods, highlighting the importance of agricultural advisory systems.
Access to credit also matters. Climate-smart agriculture often requires upfront investment—improved inputs, hired labour, or irrigation infrastructure. Without affordable credit, many farmers simply cannot take the risk.
Farm size influences adoption as well. Larger farms are more likely to experiment with new practices, while smaller farms tend to avoid risks that could threaten household food security. Distance to markets further discourages adoption by increasing transport costs and limiting access to information and inputs.
Interestingly, large household sizes reduce adoption intensity. For many families, immediate consumption needs outweigh long-term farm investments.
Why This Matters for National Policy
These findings carry clear policy implications.
First, climate-smart agriculture must be promoted beyond slogans. Farmers adopt what fits their realities. Awareness campaigns alone are insufficient without practical support.
Second, extension services deserve renewed investment. Well-trained extension officers, demonstration farms, and digital advisory platforms can bridge the gap between research and practice.
Third, climate policy must include financial inclusion. Affordable credit, tailored to horticultural crops like mango, can accelerate adoption of climate-resilient practices.
Finally, sustainability practices require incentives. Farmers are unlikely to invest in long-term soil and water conservation unless short-term support—such as subsidies, labour assistance, or climate-linked incentives is available.
A Strategic Opportunity for Ghana
Mango trees are long-term investments. Decisions made today determine productivity for decades. Supporting mango farmers to adopt climate-smart practices is not only about protecting livelihoods it is about safeguarding Ghana’s future food systems and export potential.
If properly supported, mango farmers in Yilo Krobo and similar districts could become champions of climate-resilient agriculture nationwide.
As climate change intensifies, Ghana’s response must move beyond policy documents to practical, farmer-centred solutions. Climate-smart mango farming offers one such pathway—where resilience, income, and sustainability meet.
