Agriculture in Sub-Saharan Africa is regularly threatened by the occurrence of weather shocks. We wonder whether the way farmers respond to shocks can affect land use and induce deforestation. Reviewing the existing literature, we found that this question has only been marginally studied. Drawing from the adaptation and land-use change literatures, we then expose the mechanisms through which weather shocks can push farmers to induce land-use change, or conversely to foster conservation. As farmers cope with shocks, their responses can cause degradations in ecosystems which could, in the long term, encourage deforestation and land-use change. To prepare for the next growing season, or adapt to climate variability and risk in the longer term, farmers also make structural adjustments in their farm and land-use decisions, which may lead to changes in land holding. They also resort to adaptation strategies that can indirectly affect land-use decisions by affecting households’ resources (labor, income).

撒哈拉以南非洲农业家庭对天气冲击的适应：对土地利用变化和森林砍伐的影响

撒哈拉以南非洲的农业经常受到天气冲击的威胁。我们想知道农民应对冲击的方式是否会影响土地利用并导致森林砍伐。回顾现有文献，我们发现这个问题只得到了很少的研究。从适应和土地利用变化的文献中，我们揭示了天气冲击可以推动农民诱导土地利用变化或相反促进保护的机制。当农民应对冲击时，他们的反应可能导致生态系统退化，从长远来看，这可能会助长森林砍伐和土地利用变化。为了为下一个生长季节做准备，或从长远来看适应气候变化和风险，农民还对其农场和土地使用决策进行结构调整，这可能会导致土地持有量的变化。他们还采用适应策略，通过影响家庭资源（劳动力、收入）间接影响土地使用决策。
