To cope with threats from climate change, many adaptation strategies have been widely promoted and adopted by rice farmers. This study aims to assess the impact of adaptation strategies on the income of rice farmers. To this end, the En-dogenous Switching Regression (ESR) model has been estimated. Data are from a random sample of 144 rice farmers. The results obtained show that the ESR model is statistically significant at the 1% level. Complementary irrigation, cultural diversification and the intensive rice-growing system are adaptation strategies that have positive impacts on the net incomes of rice-growers. Cultural rotation is the only strategy that has a negative impact on the net income of rice farmers. Thus, these strategies are those on which the actors of the development of the sector must carry out more concrete actions on the view of establishing a real adaptation strategy capable of mitigating the effects of climate change and improving agricultural incomes in a context of reducing hunger, poverty and guaranteeing food security.

Climatic hazards, known as anthropic issues, are permanent threat to agriculture. Thus, beside the observed new climatic conditions, several agricultural practices are being developed. This study is led in order to characterize and understand better the determinants of such the agricultural practices. Data collected from 280 maize cultivators in Northern Benin have been used to do a Multiple Correspondence Analysis (MCA) and logit models were specified. The results revealed that the perception of both the emergence of new grass species, insect pests, late starting of rains and rising temperatures influences positively the producers who, for adaptation, increase the dose of chemicals and opt for extending agriculture and adopt new varieties of seed. But, it influences negatively adopters of agroforestry and adopters of none chemical agricultural practices. Concerning the perception of the early arrival of rains, it influences positively the adoption of agricultural practices, which are likely to increase the ecological vulnerability of the producer in face of climatic hazards. Furthermore, the experience of the producer and the Access to extension service, increase the chance of adoption of ecologically unsustainable agricultural practices.
