In recent decades, unsuitable development and continued environmental degradation have endangered life support systems on earth and many organisms' survival. Poor governance and ignorance of the complex feedback of various ecosystem services have often led to depleting resources such as air, water, and soil, the destruction of ecosystems, the extinction of wildlife, widespread pollution and long-term negative consequences for humans' well-being. In water resources management systems, the dominant focus is on provisioning services with negligence of regulating and even cultural services. This study aims to assess the fit between ecosystem services uses and de facto and de jure coordination in Zayandeh Rud basin's water governance using the "socio-ecological network analysis" approach. The results showed that related uses to provisioning services such as agricultural and industrial products negatively affect regulating one. There is a synergy between regulating and cultural services. Besides, the interaction of various uses of ecosystem services in the Zayandeh Rud River is more conflictive and competitive, and the win-lose situation is evident. Despite the formal provision of de facto coordination mechanisms, the lack of coordinated programs and measures related to ecosystem services in practice, mostly regulatory and cultural sevices, is evident. These mechanisms are focused on provisioning services, and actors involved in current processes appear so far from considering mainly regulatory services. It can thus be suggested that value creation and business development from the regulating and cultural services are of paramount importance to lead non-zero sum and win-win strategies in the basin. Also, the involvement of other stakeholders like Isfahan Municipality, Cultural Heritage and Tourism Department of Isfahan Province, environmental NGO, and universities can address coordination deficit.
