Social-ecological system (SES) promoting sustainable management of natural 8 resources in common ownership area is controlled steered in a complex governance system 9 that includes regulations through laws and policies, and, management d by the 10 administrative authorities operating across structure of the related multi-level institutional 11 structures that, in turn, are governance system and shaped driven by stakeholder interests. In 42 it to define sustainable rangeland management. Well-functioning rangelands provide multiple 43 ecosystem services, such as water purification and storage, and biomass production (see Havstad et al., 2007). They also and have an important role in climate change mitigation due to their 2 capacity to sequester and store carbon in their biomass and soils (Lal, 2004; Cook et al., 2013). 3 These ecosystems provide economic and social benefits for local communities that rely on 4 utilizing rangeland resources for human livelihood (Lund, 2007). However, substantive parts of 5 the world´s rangeland systems are degraded and often ecologically dysfunctional due to 6 unsustainable land use and poor resource management approaches (Marques et al., 2016). 7 Drawing upon Ostrom (2009), rangelands in communal or joint ownership are among one 8 of among the many combined human-nature systems that are viewed as social-ecological systems 9 (SES). The SESs outcomes are the result of the interrelationship between the resource systems, 10 the actors that utilize the resources through certain resource units, and the related governance 11 system that controls and manages that utilization.
