Résumé
The communication aims enlightening the issue of climate-oriented public policy forms, scales and means of their implementation, as well as their limitations (Adelle and Russel, 2013; Howlett, 2014). Based on empirical case study in a French Caribbean island, named Guadeloupe, our study analyses the climate policy integration and urges greater consideration of the issue on the existence of so-called 'new' climate policies, thus fuelling debate on the potential emergence of a new climate-oriented public policy sector. Our discussions also foster analysis of the idea of mainstreaming international climate change governance concepts in national (Biesbroeck et al., 2010) and local (Wilbanks, 2003) policies. The Guadeloupean case study consequently focuses on analysing inter-level and -sector interactions, such that “transversal policies enhance the 'territorialization' process regarding public policy and activity areas, in turn challenging historically established sectoral boundaries” (Hassenteufel, 2011). In Guadeloupe, the State plays a critical leadership role in coordinating climate policy efforts and integrating climate change into bureaucratic and institutional structures to ensure timely and effective outcomes, that is to say that climate policy is integrated within existing structures and programs. However, but that it is not a "strong" strategy because, first, policy instruments such as MAEC (mesures agro-environnemenales et climatiques) are grabbed by bananas sector. In this way, the banana sector deprives other agricultural sectors of activities that could allow them to develop a climate policy for Guadeloupian agricultural sector. Second, adaptation of climate change is forgotten in vertical climate policy integration with the European, national and regional policy level. Finally, Adaptation to climate change is not a priority in the local agenda; she finds herself relegated behind other themes (health, development, Sargassum ...) and it is once dealt with the other emergencies settled.
