Nigerien subsistence farmers increasingly rely on marginal lands for food production as a result of ongoing soil degradation, limited fertile land availability and growing population pressure. These degraded lands, however, generally provide poor yields, which is largely assigned to an increased vulnerability to drought, as a major part of the rainfall is lost through inefficient rain water distribution. More efficient use of rainwater can be achieved with the aid of water and soil conservation (WSC) techniques, which positively alter the soil water balance in favour of productive water. In Niger, zaï and demi‐lunes WSC techniques improve yields, but their adoption has not been widespread, and the dissemination generally encounters difficulties. To identify and quantify the importance and presence of several adoption constraints in the Tillab
