Maize is one of the most common cereals and a major staple that is cultivated across all agro-ecological zones in Ghana. However, maize productivity is affected by changes in climate, such as increased temperature and variations in rainfall. These changes in climate require farmers to implement practices (adaptation strategies) in order to reduce the magnitude of crop losses. This study examined how the perceptions of maize farmers regarding climate change affect their choice of adaptation strategies. A mixed methods approach was adopted for the study. Data was collected by means of a survey of 386 maize farmers along with focus group discussions. Quantitative data were analysed with descriptive statistics, Principal Component Analysis (PCA) and multivariate probit regression, while qualitative responses were used to explain the findings. Results from the data analysis indicated that maize farmers employed 17 adaptation strategies in adapting to climate change. The most common strategies identified were change of planting days, crop diversification, use of resistant varieties, and monitoring weather forecasts on radio. Furthermore, the factors that influenced the choice of adaptation strategies by maize farmers in both zones were experience in farming, household size, and perceptions about the impact and intensity of climate change.
玉米是最常见的谷物之一,也是加纳所有农业生态区广泛种植的主要主食。然而,玉米产量受到气候变化的影响,如气温升高和降雨变化。这些气候变化要求农民采取措施(适应策略)以减少作物损失的程度。本研究考察了玉米种植农户对气候变化的认知如何影响他们对适应策略的选择。该研究采用了混合研究方法。通过对386名玉米种植农户的调查以及焦点小组讨论来收集数据。定量数据采用描述性统计、主成分分析(PCA)和多元概率回归进行分析,而定性回答则用于解释研究结果。数据分析结果表明,玉米种植农户采用了17种适应气候变化的策略。确定的最常见策略包括改变种植日期、作物多样化、使用抗性品种以及通过广播收听天气预报。此外,影响两个地区玉米种植农户选择适应策略的因素包括务农经验、家庭规模以及对气候变化影响和强度的认知。
