Worldwide water managers and policy makers are faced by the increasing demands for limited and scarce water resources, particularly in semi-arid ecosystems. This study assesses water regulation service in semi-arid ecosystems of the southeastern Iberian Peninsula. Comparisons between the supply–demand sides were analyzed across different landscape units. We mapped the biophysical supply as the potential groundwater recharged by aquifers and water supplies from reservoirs. The social demand was focused on an analysis of water consumed or used for irrigation and the stakeholder’s perceptions regarding water regulation importance and vulnerability. Results show that some landscape units are able to maintain and conserve water regulation service when the volume of recharge water by aquifers and the water supply from reservoirs is greater than its consumption (e.g. rural landscape units). However, we also found potential social conflicts in landscape units where water consumption and use is much greater than the water recharge and supply. This particularly occurs in the non-protected littoral areas with the highest water consumption and where water is perceived as a non-important and vulnerable natural resource. Overall, our results emphasized the importance of assessing ecosystem services from both supply to demand sides, for identifying social conflicts and potential trade-offs, and to provide practical information about how to integrate the ecosystem service research into landscape management and planning.  相似文献

Context

Humans continually transform landscapes, affecting the ecosystem services (ES) they provide. Thus, the spatial relationships among services vary across landscapes. Managers and decision makers have access to a variety of tools for mapping landscapes and analyzing their capacity to provide multiple ES.

Objectives

This paper characterizes and maps ES bundles across transformed landscapes in southeast Spain incorporating both the ecological and social perspectives. Our specific goals were to: (1) quantify ES biophysical supply, (2) identify public awareness, (3) map ES bundles, and (4) characterize types of ES bundles based on their social-ecological dimensions.

Methods

Biophysical models and face-to-face social surveys were used to quantify and map ES bundles and explore the public awareness in a highly transformed Mediterranean region. Then, we classified ES bundles into four types using a matrix crossing the degree of biophysical ES supply and the degree of social awareness.

Results

Results mapped seven ES bundles types representing diverse social-ecological dynamics. ES bundles mapped at the municipality level showed mismatches between their biophysical provision and the public awareness, which has important implications for operationalizing the bundles concept for landscape planning and management. ES bundles characterization identified four types of bundles scenarios.

Conclusions

We propose an ES bundles classification that incorporates both their social and ecological dimensions. Our findings can be used by land managers to identify areas in which ES are declining as well as priority areas for maximizing ES provision and can help to identify conflicts associated with new management and planning practices.
