This paper explores farmers' willingness to be (better) informed about reaction options to climate change and to pay for agricultural extension as related to modes of adaptation to climate change. Following a contingent valuation approach, the study was conducted through a survey on 336 producers farmers in northern Benin (West Africa). The results show that farmers were very willing to be informed about both climate change (predictions) and documented adaptation (strategies). However, they are willing to pay more for documented climate change adaptation strategies than for climate change predictions. The Heckman probit and seemingly unrelated regression models highlighted that age, gender, level of education, experience in agriculture, access to credit, organization membership, contact with extension, perception of and adaptation to climate change, and farm size have differential effects on farmers' behaviours towards agricultural extension services related to climate change.
