Fernandez-Canero, Rafael | Ordovas, Jose | Herrera Machuca, Miguel Angel
Spain has undergone a period of uncontrolled urban expansion in a relatively short time-span, affecting people's quality of life in negative ways with significant impacts on the environment and land resources such as water and energy. Many new residential areas have low-density development, based on single-family houses with private gardens. These gardens are usually relatively small in size, but when considered as a whole, they make a substantial contribution to urban green spaces and have an important impact on the local environment. Although this includes a large variety of benefits, gardens demand a significant quantity of resources, including irrigation water, which is also important and should be taken into account. This paper analyzes features and management practices in domestic gardens, their relationships to garden design, and the attitudes of owners with regard to more sustainable alternatives. In addition, the main features of private gardens are examined. For this study, in-person interviews were conducted with homeowners who possess domestic gardens in the region of Aljarafe in southern Spain. The features of the gardens surveyed proved to be highly variable and related to several factors, such as the area of the gardens. Results seem to indicate that owners are reluctant to implement measures to lower water consumption in garden irrigation, apparently because of a lack of knowledge regarding more sustainable design alternatives. Homeowners who had prior knowledge of the principles of xeriscaping were significantly more open to applying these principles in practical ways.
