How adjustments in land use patterns contribute to drought risk adaptation in a changing climate—A case study in China

摘要

In the context of climate change, adaptation to climatic extremes, such as drought, has attracted worldwide attention, yet many practical adaptation strategies need to be examined at the local level. Based on a case study of the village of Beidian, located in a drought-prone region in northern China, this study demonstrates that when faced with multiple pressures of regional climate change, drought risk and rural poverty, reasonable adjustments in land use patterns can serve as an effective adaptation strategy in the agricultural sector. We used household questionnaires, in-depth interviews with village managers, and land use surveys at the farming plot level to quantify the relationship between land use change and drought mitigation effects. Our findings indicate that in the past decade, the farming practices in Beidian have transformed from a complete reliance on the winter wheat-summer corn rotation to a new diversified mode of apple as the main crop and corn and coarse cereals as the subsidiarycrops. The current farming mode is proven to possess a stronger adaptive capacity to drought due to its higher water-saving efficiency and economic benefit, which facilitates rural poverty reduction and socio-economic development. This study presents afeasible approach to address adaptation strategies at the local level, which provides policymakers with information on how to best support farm-level adaptation and to reduce farmers' vulnerability to climatic extremes within the broader context of climate change.
