评估区域范围内农业系统对气候变化和变异性的脆弱性对于保障粮食和纤维系统以及维持农村生计至关重要。农民、牧场主和林地所有者依靠基于科学的、与决策相关的本地化信息来维持生产、生态活力和经济回报。本文综合了有关美国西南部农业生产未来的研究成果。各种评估方法表明西南部地区存在不同的影响和风险，这些影响和风险通常与水资源的可用性有关，这推动了该地区采取适应性措施。该地区长期以来一直采取针对特定部门或物种的适应性措施，并将继续作为支持区域企业的农业生产所必需的。作物选择和收入来源的多样化赋予了气候适应能力。通过纳入社会和经济因素来建立生物物理脆弱性对于未来的适应规划工作至关重要。水资源有限的西南部地区农业的持久性和适应能力可以为该地区以外预期干旱和温暖条件的生产者提供指导性范例，并可能为减少未来气候影响提供解决方案。
Assessing regional-scale vulnerability of agricultural systems to climate change and variability is vital in securing food and fiber systems, as well as sustaining rural livelihoods. Farmers, ranchers, and forest landowners rely on science-based, decision-relevant, and localized information to maintain production, ecological viability, and economic returns. This paper synthesizes the collection of research on the future of agricultural production in the Southwestern United States. A variety of assessment methods indicate the diverse impacts and risks across the Southwest, often related to water availability, which drives adaptive measures in this region. Sector- or species-specific adaptive measures have long been practiced in this region and will continue to be necessary to support agricultural production as a regional enterprise. Diversification of crop selection and income source imparts climate resilience. Building upon biophysical vulnerability through incorporating social and economic factors is critical to future adaptation planning efforts. The persistence and adaptive capacity of agriculture in the water-limited Southwest serves as an instructive example for producers outside the region expecting drier and warmer conditions and may offer solutions to reduce future climate impacts.
