Abstract: This study aims to analyze the perception of producers on agro-ecological practices in cotton growing areas in Benin. To do this, data was collected from 300 producers in three municipalities (Banikoara, Sinendé and Djidja) using a semi-structured questionnaire digitized on Kobocollecte. The calculation of the response rates and the ascending hierarchical classification carried out using the statistical software Ri386.4.0.4, made it possible to arrive at three classes of agro-ecological practices according to the perception of the producers. These classes of practices are: lightly restrictive, moderately restrictive and very restrictive. The major constraints are organizational, material, climatic and institutional. The study recommends strengthening the supervision of producers and taking into account the socio-economic characteristics of producers in the promotion of agro-ecological practices in cotton-growing areas.

The objective of this study is to determine the perception of corn producers on soil quality based on sustainable land management practices in the Okpara watershed. To do this, 280 heads of maize producers were surveyed in the municipalities of Pèrèrè, N’Dali, Tchaourou and Ouessè. The Fisher test made it possible to compare the soil quality score according to the municipalities, the farming practices of the Okpara watershed; the score of soil types according to farming practices and municipalities. This test showed that the municipalities of Pèrèrè and N’Dali have better soil quality scores than the municipalities of Tchaourou and Ouessè regardless of the type of soil. Multiple linear regression has shown that factors such as: the probability of predicting improved seed practices, the probability of ridging practices, the municipality of Tchaourou, the municipality of Ouessè, and the number of years of experience in agriculture in general significantly determine the quality of the soil in the Okpara watershed. Thus, it is therefore necessary to take into account the endogenous knowledge available to producers in the study area for a better assessment of the quality of the soil in future studies.

The development of fish farming in Benin is facing enormous constraints. For sustainability of fish farming systems, these constraints must be removed. The objective of this research is to identify the determinants of the ecological sustainability of fish farming systems in the Ouémé valley in southern Benin. For this, 300 fish farmers randomly selected were surveyed in four communes of the Ouémé Valley. These are the communes of Ouinhi, Bonou, Adjohoun and Dangbo. The Ecological Sustainability Score (EDS) was calculated using the IDAqua Approach that uses the sustainability indicators in aquaculture. Then a multiple linear regression was used to identify the factors determining the level of ecological sustainability of fish farming systems. The results indicate globally, fish farmers have an ecological sustainability score of 39.25 out of 100. The regression carried out showed that the level of ecological sustainability of fish farming systems in the Ouémé valley in southern Benin are economic efficiency, the level of primary schooling, the level of higher education and fish farming as the main activity. The results suggest that the authorities are putting in place policies where fish farmers are themselves trained to produce the foods they use while minimizing production costs. Under these conditions, one could expect an improvement in the ecological sustainability of fish farming systems.
