Revisiting Yields: A Replication Study on Climate-Resilient Rice Varieties among Coastal Ghanaian Farmers,

This study revisits the adoption rates of climate-resilient rice varieties among coastal Ghanaian farmers to assess yield increments over a single year. A replication study design was employed, involving interviews with farmers who adopted climate-resilient varieties. Data were collected using a structured questionnaire designed to ensure consistency across all respondents. The analysis revealed that climate-resilient rice varieties significantly increased yields by an average of 15% compared to traditional cultivars, with notable variance in responses from different farming communities. The replication study confirms the efficacy of climate-resilient varieties in enhancing agricultural productivity among coastal Ghanaian farmers, supporting previous research findings. Farmers and policymakers should be encouraged to adopt these new rice varieties as part of sustainable agriculture strategies to mitigate climate impacts on crop yields. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
