Abstract

ABSTRACT Most studies on hazards to smallholder farmers focus on the impact of climate variability on their livelihoods. However, climate variability does not exist in isolation; rather, it manifests in combination with a multiplicity of stressors. This paper examines the perceptions of the influence of climate variability on multiple stressors affecting the agricultural livelihoods of smallholder farmers in an irrigation system in southern Mexico. An ethnographic approach was used to conduct a qualitative study of 85 smallholder farmers in four communities. The results showed that farmers are affected by several biophysical (e.g. water scarcity, crop disease) and socioeconomic (e.g. market price problems, high cost of chemical inputs) stressors that interact with climate variability. Farmers perceived increase in temperature, decrease in rainfall, and changes in the rainfall pattern (onset of the rainy season, its duration or cessation) as amplifying the stressors of water scarcity and crop disease. The results suggest that policies should go beyond the impacts of climate variability on agricultural livelihoods and consider the full range of socioeconomic impacts. Furthermore, the differences in perception regarding stressors and climate variability in communities point to the need for effective implementation of policies adapted to local conditions.
在多重压力源背景下气候变率对墨西哥南部小农的感知影响
大多数关于小农灾害的研究都集中在气候变化对其生计的影响上。然而,气候变率并非孤立存在;相反,它与多种压力源结合在一起。本文考察了气候变率对影响墨西哥南部灌溉系统中小农农业生计的多种压力源的影响的看法。采用民族志方法对四个社区的85名小农进行了定性研究。结果表明,农民受到几种生物物理(如缺水、作物病害)和社会经济(如市场价格问题、化学品投入成本高)压力因素的影响,这些压力因素与气候变率相互作用。农民认为,气温升高、降雨量减少以及降雨模式的变化(雨季开始、持续时间或停止)加剧了水资源短缺和作物病害的压力因素。研究结果表明,政策应超越气候变率对农业生计的影响,并考虑全面的社会经济影响。此外,社区对压力源和气候变化的认识差异表明,需要有效执行适应当地条件的政策。
