气候变化正在挑战城市农业生态系统服务的持续提供。由于水资源供应有限，极端、长期干旱加上高温事件影响城市作物生产，并影响环境管理和对环境条件的适应。在这项研究中，我们使用加州中部海岸的城市社区花园作为一个系统来调查人们如何在三个时期内适应他们的管理行为——在加州最近历史上最长的干旱之前、期间和之后。我们特别询问了水政策和园丁特征（包括园艺经验、正规教育、干旱关注和与自然的关系）如何影响行为变化。通过结构方程模型和多变量分析，我们发现自然相关性和园艺经验影响干旱关注，进而影响行为变化，以及园丁可持续管理水和适应干旱条件的潜在能力。种植动机也很重要，随着时间的推移会影响人们对实践的采用和保留。然而，在缺乏关注的地方，水政策能够促进和维持行为改变和基于保护的实践采用。因此，需要环境意识和经验与政策相结合，以促进和支持主动的行为改变和适应，从而在气候变化下建立有弹性的城市粮食生产系统。
Climate change is challenging the sustained delivery of ecosystem services from urban agriculture. Extreme, prolonged drought in combination with high heat events affect urban crop production due to limited water availability and affect environmental management and adaptation to environmental conditions. In this study, we use urban community gardens in central coast California as a system to investigate how people are adapting their management behaviors over three time periods-before, during and after the longest drought in California's recent history. We specifically ask how behavioral change is impacted by water policies and gardener characteristics (including gardening experience, formal education, drought concern, and relationship to nature). Through structural equation modeling and multivariate analyses, we show that nature relatedness and gardening experience impact drought concern which in turn impact behavioral change, and potentially gardener's ability to sustainably manage water and to adapt to drought conditions. Planting motivations are also important, influencing people's adoption and retention of practices over time. Yet where concern may be absent, water policies are able to promote and maintain behavioral change and conservation-based practice adoption. Thus, environmental awareness and experience in combination with policies are needed to promote and support proactive behavioral change and adaptation to create resilient urban food production systems under climate change.
