摘要

美国西部的生态服务和灌溉都严重依赖于稀缺的水资源。然而,干旱期间灌溉用水的反应并没有得到很好的记录。灌溉决策非常复杂,受到输水量、作物产量、设备、劳动力、作物价格和气候多变性等人为和环境因素的影响。虽然很少有灌区计划在干旱期间减少输水量,但水权、休耕模式、作物轮作和利润预期也会影响农场规模的灌溉管理。本研究利用高分辨率卫星数据,采用新的灌溉管理衡量标准--标准化灌溉管理指数,研究灌溉者对干旱的反应。我们从气候和河流流量的角度评估了田间和流域尺度的干旱状况,并分析了作物价格和干旱状况的变化对决策和用水的影响。我们发现田间尺度对干旱的反应存在很大差异,作物类型、灌溉类型和联邦管理解释了区域和田间尺度的差异。气候和价格对作物转换的相对影响表明,价格对作物种植决策的驱动力更大。该研究为干旱期间的灌溉管理提供了见解,这对美国西南部持续的供水危机下的可持续供水至关重要。

Irrigation response to drought in the Western United States, 1987–2021

Irrigation response to drought in the Western United States, 1987–2021

The Western United States (U.S.) relies heavily on scarce water resources for both ecological services and irrigation. However, the response of irrigation water use during drought is not well documented. Irrigation decision-making is complex and influenced by human and environmental factors such as water deliveries, crop yields, equipment, labor, crop prices, and climate variability. While few irrigation districts have plans to curtail water deliveries during droughts, water rights, fallowing patterns, crop rotations, and profit expectations also influence irrigation management at the farm scale. This study uses high-resolution satellite data to examine the response of irrigators to drought by using a novel measure of irrigation management, the Standardized Irrigation Management Index. We assess the state of drought at the field and basin scales in terms of climate and streamflow and analyze the importance of variations in crop price and drought status on decision-making and water use. We show significant variability in field-scale response to drought and that crop type, irrigation type, and federal management explain regional and field-scale differences. The relative influence of climate and prices on crop transitions indicate prices more strongly drive crop planting decisions. The study provides insights into irrigation management during drought, which is crucial for sustainable water supply in the face of the ongoing water supply crisis in the U.S. Southwest.

期刊介绍: JAWRA seeks to be the preeminent scholarly publication on multidisciplinary water resources issues. JAWRA papers present ideas derived from multiple disciplines woven together to give insight into a critical water issue, or are based primarily upon a single discipline with important applications to other disciplines. Papers often cover the topics of recent AWRA conferences such as riparian ecology, geographic information systems, adaptive management, and water policy. JAWRA authors present work within their disciplinary fields to a broader audience. Our Associate Editors and reviewers reflect this diversity to ensure a knowledgeable and fair review of a broad range of topics. We particularly encourage submissions of papers which impart a ''take home message'' our readers can use.
