The evolution of cooperative forms on the one hand and the emergence of environmental issues on the other hand have reopened the debate on the governance of cooperatives, their environmental involvement and the effects of this involvement on their performance. This thesis focuses on the governance of Cooperatives for the Use of Agricultural Equipment (CUMA) and on the effect of governance on environmental investments and the implication of these investments on CUMA performance. Through a mixed approach combining a qualitative approach, a two-part econometric model with selection and a dynamic frontier analysis, our results highlight the ability of CUMA members to coordinate effectively by using mainly relational governance mechanism.The willingness of CUMAs to maintain this type of mechanism influences the size of the group, which becomes critical beyond a threshold by limiting their propensity and proportion to become involved in environmental issues. However, the environmental involvement of CUMAs is necessary and beneficial for their economic performance when environmental investments are made in equipment of first choice.
