Short answer

Designers should actively advocate for and implement plant palettes and landscape structures that minimize water demand, especially in regions prone to water scarcity.

Field: Resource Management
Source: HortTechnology (2014)
Method: Mixed-methods research combining quantitative data collection (plant lists, area measurements, watering system assessment) with qualitative data from owner interviews.
Sample: 258 participants
Evidence: Strong effect

The selection of plant species, particularly the prevalence of turfgrass, and the presence of professional landscaping are strongly correlated with higher water requirements in private gardens. This resource management research insight is drawn from a 2014 study published in HortTechnology. Using Mixed-methods research combining quantitative data collection (plant lists, area measurements, watering system assessment) with qualitative data from owner interviews. with 258 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should actively advocate for and implement plant palettes and landscape structures that minimize water demand, especially in regions prone to water scarcity.

Garden Design Choices Significantly Impact Water Consumption in Mediterranean Climates

The selection of plant species, particularly the prevalence of turfgrass, and the presence of professional landscaping are strongly correlated with higher water requirements in private gardens.

HortTechnology · 2014

Key Findings

01The presence of turfgrass is linked to professional landscaping, property age, and the existence of swimming pools.
02Gardens with higher water requirements tend to utilize more efficient watering systems.
03A strategy for garden restructuring can reduce water use and increase the presence of fruit trees and orchards.

Application

Design takeaway

Designers should actively advocate for and implement plant palettes and landscape structures that minimize water demand, especially in regions prone to water scarcity.

How to apply

When designing for clients in similar climates, present options that clearly outline the water usage differences between various plant types and landscape styles, and recommend efficient irrigation systems.

Project actions

01When researching plant choices for a design project, always consider the water requirements of each species in the target climate.
02Investigate different irrigation systems and their efficiency levels for your chosen plants.

Method & Evidence

AimTo investigate the relationship between garden features, management practices, and water consumption in private gardens within a Mediterranean climate.

MethodMixed-methods research combining quantitative data collection (plant lists, area measurements, watering system assessment) with qualitative data from owner interviews.

ProcedureResearchers cataloged plant species and vegetation cover in 258 private gardens, interviewed owners about garden management and recent/planned modifications, and assessed watering system efficiency.

Sample258 participants

ContextPrivate domestic gardens in the Alt Empordà region of Catalonia, Spain.

Variables

IV["Presence of turfgrass","Professional landscaping","Property age","Presence of swimming pool","Garden restructuring strategy"]

DV["Relative water requirements of the garden","Watering system efficiency"]

CV["Geographic location (Alt Empordà, Spain)","Mediterranean climate"]

Strengths & Limitations

Strengths

+Large sample size for a study of this nature.
+Combines quantitative data with qualitative insights from interviews.

Limitations

The cost and availability of drought-tolerant plants or advanced irrigation systems might be a barrier for some clients or projects.

Reliability & validity

The study's reliability is supported by a large sample size and systematic data collection. Validity is enhanced by correlating multiple garden characteristics with water use, though self-reported data and regional specificity are potential limitations.

Think critically

To what extent should aesthetic preferences be compromised for water conservation in design projects, and how can designers effectively communicate these trade-offs to clients?

Design Principles

"Sustainable landscape design in water-stressed environments necessitates a careful balance between aesthetic goals, functional requirements, and ecological impact, with a strong emphasis on water conservation."

Designers and landscape architects working in water-scarce regions must consider the long-term water implications of their aesthetic and functional choices. Understanding these correlations can guide the development of more sustainable and resilient garden designs.

What This Means for Your Design

The plants you choose for a garden and how it's designed can make a big difference in how much water it uses, especially in dry places like Spain. Lawns and fancy designs often mean more water use.

Paragraph starter

Research indicates that landscape design choices, such as the inclusion of turfgrass and the reliance on professional landscaping, are strongly correlated with increased water consumption in private gardens, particularly within Mediterranean climates. This highlights the critical need for designers to prioritize drought-tolerant species and efficient irrigation systems to mitigate water scarcity.
