Abstract: The effects of climate change add to the challenges facing those with rice‐based livelihoods in West Africa. This article presents a long‐term ethnographic case study in southern Guinea‐Bissau where, in contrast to other reported cases in the region, uncertainty regarding the future of mangrove rice production overlaps with efforts to rehabilitate abandoned mangrove rice paddies. Agricultural knowledge is produced, renewed and transmitted along with the construction of site‐specific, techno‐ecological hybrids needed for water management in rice fields. This article analyses the role of communal, reciprocal and contract labour in the circulation of knowledge between villages with historically stable rice production (rice refugia) and villages where production has been discontinuous (rice margins). Knowledge circulation and experimentation are key to local adaptation to climate change and climate resilience programmes can play a role if they are able to adapt to current needs, for instance, by considering decentralized funding strategies. By promoting the exchange of services and goods, decentralization of funding can facilitate the redistribution of knowledge and labour, particularly if rice refugia, as regional knowledge repositories, participate in the recovery of rice production in rice margins. These connections revitalize and strengthen regional rice knowledge networks and their ability to confront climate change.
