Climate change and food security are critical topics in sustainable agricultural development. Climate change is expected to have serious environmental, economic and social impacts on Sri Lanka. Coconut growers’ knowledge, perception level and adoption for climate change adaptation measures have influenced productivity of the coconut cultivation. The study investigated the coconut growers’ knowledge gap, knowledge and perception levels regarding impacts of climate change in Gampaha and Puttalam districts. Further, this study investigated their adoption of different adaptation measures. A stratified random sampling technique was applied for selecting 240 respondents from two different districts. Structured questionnaire and interview schedule were used to elicit information from the respondents and data was analyzed with both descriptive and inferential statistics. Adoption rate of the climate change adaptation measures is significantly influenced by coconut growers’ knowledge and perception level at varying degrees. The study revealed that most of the growers in two study areas have better knowledge (> 70%) and perceptions (>60%) regarding the gradual changes in the climate and its impact on their coconut cultivation. However, their adaptation behavior is fairly poor (< 50%) in both districts. Hence government policies should more focused on to coconut growers to have access to affordable credit to increase their ability and flexibility to change adaptation strategies in response to the changing climatic conditions. Increasing growers’ access to agricultural extension services and access to information on weather forecasting are very important. In addition, government should improve and promote off-farm income-earning opportunities during dry seasons.
Contribution/ Originality
This study is one of the very few studies which use novel index-based approach to investigate coconut growers’ knowledge, perception and adoption on impacts of climate change in Gampaha and Puttalam districts.
