Assessing landscape functions with broad-scale environmental data: insights gained from a prototype development for...

Area of Science:

• Ecology
• Environmental Science
• Land Use Planning

Background:

• Understanding landscape functions, or the capacity of land to provide ecosystem services, is crucial but complex.
• Existing methods often struggle to capture the intricate relationships between land properties and service provision.

Purpose of the Study:

• To evaluate a methodological framework for analyzing landscape functions using expert- and literature-driven binary links.
• To assess the spatial explicit landscape function assessment across 581 European administrative units.
• To test the framework's reliability by comparing its outputs with independent assessments of ecosystem services and environmental indicators.

Main Methods:

• Developed a framework based on binary links defining the role of land uses/properties for specific landscape functions.
• Applied these links to environmental data from 581 European units, creating spatially explicit landscape function maps.
• Validated the maps by comparing them with existing continent-wide ecosystem service and environmental indicator assessments.

Main Results:

• The binary link framework successfully generated plausible geographical patterns for 9 out of 15 landscape functions.
• The method proved most effective for production functions.
• Analysis using four land use scenarios (IPCC SRES) indicated that most European regions can maintain service provision capacity, though locations may shift.

Conclusions:

• The proposed methodological framework, using straightforward binary links, is a valid and effective tool for assessing landscape functions at a continental scale.
• The framework's input parameters serve as reliable proxies for evaluating the mid-term potential of landscapes to provide essential goods and services.
• The study highlights the robustness of simplified models in predicting ecosystem service provision under changing land-use conditions.
