Climate change studies for West Africa tend to predict a reduced potential for farming that will affect the food security situation of an already impoverished population. However, these studies largely ignore farmers' adaptations and market adjustments that mitigate predicted negative effects. The paper attempts to fill some of this gap through a spatially explicit evaluation of the impact of climate change on farm income in the Oueme River Basin (ORB), Benin. The ORB is in many respects representative for the middle belt of West Africa where the predominantly sparse occupation leaves potential for migration from more densely populated areas. We apply a number of structural, spatially explicit relationships estimated for the whole territory of Benin to simulate conditions in the ORB proper that are similar to those currently prevailing in the drier North, and the more humid South. Our scenario results factor out for the main crops cultivated the constituent effects on yields, area, and revenue per ton. We find that under average climate change conditions the current low yields are not reduced, provided that cropping patterns are adjusted, while price increases partly compensate for the remaining adverse effects on farmer income. Consequently, without any policy intervention, farm incomes remain relatively stable, albeit at low levels and with increased occurrence of crop failures after extreme droughts. Scenario simulations show that there are also beneficial aspects that can, with adequate interventions, even turn losses into gains. Main channel for improvement would be the reduction of fallow, which is particularly promising because it requires few adjustments in prevailing farming practices, exploits the potential of uncultivated land and improves the water use efficiency. It also enables the Basin's capacity to absorb future migrant flows from more severely affected neighboring Sahelian areas. [ABSTRACT FROM AUTHOR]

The use of synthetic pesticides among vegetable producers in urban and peri-urban Cotonou, Benin, has been increasing to the extent that certain insect pests have developed resistance to the pesticides. This paper assesses the impact of the farmer field school approach in an integrated pest management (IPM) project that aimed to increase IPM knowledge, adaptation/adoption of IPM options, and appropriate application of pesticides and awareness of related health hazards among vegetable producers in Cotonou. A sample of 54 semi-structured interviews was conducted with the vegetable producers, and a double difference model was used to compare the knowledge and practices before and after the project. The project led to increased knowledge about IPM, which was to some extent adapted into the participants" production systems, although no significant difference was noted for the type of synthetic pesticides used. The producers do adapt their practices when new technologies and practices emerge, but not always in ways that are environmentally sound or healthy. [ABSTRACT FROM AUTHOR]

Resilience, adaptation and mitigation are unique but complimentary actions in the fight against climate change (CC), particularly in developing countries. Although evidence suggest the inclusion of stakeholder opinions as part of the frameworks for combating CC, this evidence is not well substantiated, and is not extensively described in sub-Sahara African CC literature. While language remains a big issue in CC discussions, processes comprised within climate actions are equally as important as both the language and the results. It is on the basis of the confusion surrounding the language adopted as actions geared towards combating CC that this study seeks to examine the opinions/perception of CC actors in three West African nations. It looks at perceived and/or suitable solutions to selected CC-imposed challenges in the midst of socio-economic and environmental concerns. A total of 475 individuals, representing NGOs, public and private organizations involved with CC issues, as well as private persons concerned about CC, were recruited across Nigeria, Niger, and Benin, over a two-year period (April 2017–April 2019). A questionnaire containing 15 items was administered. The results of data analysis using chi-square and Fischer's exact tests show that the mean number of CC actors differs within and across all three countries for all climate action types against CC-imposed challenges. While CC adaptive plans and projects are thought to yield immediate results, they are also observed to be cheaper in comparison to mitigation and resilience projects. [ABSTRACT FROM AUTHOR]
