摘要

小农户的抗灾能力是他们在脆弱的旱地地区继续耕作和投资的主要驱动力之一。本文旨在评估塞内加尔卢加、卡夫林和蒂斯三个旱地次区域小农户面对气候变化时的抗灾能力概况及其影响因素。我们利用农民对气候变异性的看法以及他们在气候冲击下的承受、适应和反弹能力的数据,制定了气候复原力综合指数(CICR)。干旱、强风和气候变化导致的土壤肥力下降是影响小农耕作系统的主要气候灾害。CICR 值从最脆弱家庭的 -2 到最具复原力家庭的 +2 不等。平均而言,所有家庭都是脆弱的,平均 CICR 值为-0.2。LOUGA 地区最脆弱,平均 CICR 值为-0.36,其次是 THIES 地区(-0.2)。卡夫林地区的脆弱性相对较小,CICR 值为-0.1。有序对数模型的估计结果表明,随着户主年龄的增加,提高 CICR 的几率会降低,直至 59 岁。接受气候智能型农业(CSA)实践和气候信息培训似乎有可能使家庭提高抗灾能力的几率增加 171%。分析还显示,多一名妇女在农场外或家中从事园艺工作,家庭提高抗灾能力的几率就有可能增加四倍。这凸显了增强妇女权能以提高家庭抵御气候变化能力的重要性。非农业收入使农户提高抗灾能力的几率增加了 62%,获得转移性收入的几率增加了 50%。这项研究为量化抗灾能力或福祉及其驱动因素提供了一种可靠的方法,丰富了我们对西非农民抵御气候变化能力的了解。它有助于设计有效的适应干预措施,改善小农的整体福祉。

Vulnerability and resilience in the face of climate changes in Senegal's drylands: measurement at the household level and determinant assessment
The resilience capacity of smallholder households is one of the main drivers of their ability to continue to farm and make investments in the fragile dryland regions. This paper aims to assess the resilience profile of smallholder farmers in the face of climate change and the factors influencing it in three dryland sub-regions of Senegal, namely, Louga, Kaffrine, and Thies. We developed a composite index of climate resilience (CICR) using data on farmers' perceptions of climate variability and their perceived ability to withstand, adapt, and bounce back in the event of climatic shocks. Drought, strong winds, and soil fertility decline because of climate change emerged as the main climate hazards impacting smallholder farming systems. The CICR value ranged from −2 for the most vulnerable households to +2 for the most resilient households. On average, all the households were found to be vulnerable, with an average CICR value of −0.2. The LOUGA region was the most vulnerable, with an average CICR value of −0.36, followed by THIES (-0.2). The KAFFRINE region was relatively less vulnerable, with a CICR value of −0.1. Ordered logit model estimates show that the chances of improving CICR decrease with the increase of the household head's age until 59 years. Access to training on climate-smart agricultural (CSA) practices and climate information appeared to have the potential to increase by 171% the chance of the household improving its resilience status. Analysis also shows that one more woman working off-farm or in-home gardening has the potential to multiply by four times the chances of households being more resilient. This highlights the importance of empowering women to enhance household resilience to climate change. The off-farm revenue increased the chance to improve the resilience status of the farm household by 62% and the receipt of transfer revenue by 50%. This study provides a robust method for quantifying resilience or wellbeing and its drivers and enriches our understanding of the resilience ability of farmers to climate change in a West African context. It can be useful in designing effective adaptation interventions and improving the overall wellbeing of smallholder farmers.
