Abstract:
The ubiquity of residential land uses place them at the center of landscape sustainability, which has been defined as the capacity of landscapes (inclusive of natural and built elements) to maximize ecosystem services while minimizing disservices. With the prevalence of lawns in residential land systems, scholars and conservations have raised concerns about their ecosystem disservices (i.e., negative environmental impacts), which include high water use and diminished biodiversity. To address these concerns, yard alternatives have emerged such as low water-use “xeric” landscapes and wildlife gardens. In this talk, I will share empirical results on the complex dynamics shaping residential land management decisions, which in turn affect sustainability outcomes—specifically, water conservation and biodiversity preservation. Additionally, I will reveal important, evidence-based considerations underpinning the social sustainability of residential landscapes, which requires designing and managing yards in ways that are aesthetically appreciated and easy to maintain. My talk contains two parts focusing on: 1) the factors affecting the adoption of xeric, water-conserving yards in metro Phoenix, AZ, some of which defy common assumptions about residents’ decisions and associated landscape change; and 2) the priorities that enable and constrain gardening for wildlife in residential areas across metropolitan regions of the US. In the second part, I will also demonstrate the significant impacts of wildlife gardens on plant and bird diversity based on interdisciplinary social-ecological research. To conclude, I offer suggestions on pursuing ecologically beneficial landscapes that garner public appreciation and maintenance over time, while also providing recommendations to advance landscape sustainability based on empirical evidence.
