"This study aimed to highlight the issue of climate-oriented public policy forms, scales, and means of their implementation as well as their limitations. Based on an empirical case study of the French West Indies (Guadeloupe), we analyzed climate policy integration in programmatic local policies and sectoral practices. This study sheds light on the banana sector and how climate change is mainstreamed at a local level. In Guadeloupe, the climate change paradigm is grabbed and `invisibilized' into sectoral policies and practices. By paying attention to who implements the policies regarding the adaptation of agriculture to climate change (AACC) and how, we highlighted the capacity of the banana sector to retrieve policy instruments dedicated to the AACC to support their own agricultural and environmental agenda. We also paid attention to their local and sectoral transfer and their `fluid' implementation: implementation is multiform, compelled by limitations. Finally, we concluded that implementation of the AACC policy depends on four variables: (a) the multilevel governance and the complex process of reinterpretation of European Union (EU) policy and rules, (b) the specific polycentric governance style (c) that is centered on a powerful banana chain, and (d) the environmental agenda that gives priority to local vulnerabilities."
