摘要：Freshwater ecosystems deliver an extensive range of ecosystem services (ESs), which are the benefits people obtain from their interaction with nature. Increasing pressure on water resources threatens the sustainable supply of water-related ecosystem services, especially in arid regions, as is the case for the Drâa Valley located in southern Morocco. With the long-term objective of contributing to a sustainable supply of important ecosystem services in the Drâa Valley, this paper analyzes stakeholder perceptions of water-related ecosystem services (WESs). To assess the different perceptions of WES, 35 semi-structured interviews were conducted with the inhabitants of three oases in the middle Drâa Valley, as well as 12 other interviews with key government officials. Based on our interviews, we reflect on two of the policy-relevant generic principles proposed by the Stockholm Resilience Centre for enhancing the resilience of WESs. Our results reveal similarities in perceptions of WES among stakeholder groups regarding provisioning services but marked differences regarding regulating and cultural services. The analysis suggests that these differences stem from stakeholders’ different roles and activities in the area. In addition, socio-demographic, biophysical, and spatial aspects also shape how WESs are perceived in the area. Learning about similarities in WES perceptions can help build common ground among stakeholders. The recognition of differences can also assist the balancing of the different needs and interests of these groups. ESs perception assessment can contribute to strengthened stakeholder knowledge of the categories of ESs and provide a common ground for participating in ES-related decision making, hence enhancing resilience in social–ecological systems.
