With climate change, water-limited cities face difficulties in maintaining historic watering levels in urban parks, leading park managers to consider changes to park designs. Public preferences for different park designs in Perth, Australia were assessed using a choice experiment, revealing acceptance of both irrigated and non-irrigated alternatives. Incorporating at least 40% native vegetation groundcover can increase the utility derived from parks and conserve water, while park managers have flexibility in designing parks that still provide near-optimal benefits to communities.
With climate change, it is becoming more challenging for water-limited cities to sustain historic watering levels in urban parks, leading park managers to consider changes to park designs. However, the extent to which people value parks that deviate from conventional designs featuring primarily irrigated lawn remains uncertain. We use a choice experiment to assess public preferences for different park designs in Perth, Australia. With a scale-adjusted latent class model, we identify optimal groundcover compositions for four preference classes. We find that while having some watered grass in urban parks is important, the public are also accepting of non-irrigated alternatives. Incorporating at least 40% native vegetation groundcover can both increase the utility the public derives from parks and conserve water. Park managers also have a high degree of flexibility in designing parks that vary from the optimal groundcover composition but that still deliver near-optimal benefits to communities.
