“…This becomes a potential for interdisciplinary planning and management processes in SES, particularly for the support decision-making processes at the local level. However, in this review, we can highlight few cases using dynamic spatially distributed models for integrated approaches [57,[97][98][99][100].…”

Scenario analysis is a useful tool to facilitate discussions about the main trends of future change and to promote the understanding of global environmental changes implications on relevant aspects of sustainability. In this paper, we reviewed 294 articles published between 1995–2019, to evaluate the state of the art use of models and scenarios to investigate the effects of land use change and climate change on natural and social-ecological systems. Our review focuses on three issues. The first explores the extent to which the environmental dynamics of land use and climate change were jointly analyzed and the spatial scales associated with such integrated studies. The second explores the modelling methodologies and approaches used in the scenario analysis. The third explores the methods for developing or building scenarios. Results show that in most predictions there is little integration of key drivers of change. We find most forecasting studies use a sectoral modelling approach through dynamic spatially distributed models. Most articles do not apply a participatory approach in the development of scenarios. Based on this review, we conclude that there are some gaps in how scenario analysis on natural and social-ecological systems are conducted. These gaps pose a challenge for the use of models and scenarios as predictive tools in decision-making processes in the context of global change.

“…The selected hydrological model should have enough flexibility and capability of implementing different components of the basin's hydrology by a user (Devia et al, 2015; Sood & Smakhtin, 2015). In this regard, SWAT is one of the most comprehensive models used in various studies globally, including Black Sea Basin (Rouholahnejad et al, 2014), Basins in Switzerland (Abbaspour et al, 2007; Lehmann et al, 2019), and continental Africa (Schuol et al, 2008). Also, in the Iranian basins, including Karkheh River Basin (Vaghefi et al, 2015), Zarrineh Rood (Ahmadzadeh et al, 2016), and Tashk‐Bakhtegan (Nalbandan et al, 2023), Minab (Yousefi & Moridi, 2022), Harirud (Nazari Mejdar et al, 2023) and Zayandeh‐Roud (Jalali et al, 2021; Saedi et al, 2021), SWAT's capability to fill missing data using weather generator, auto‐irrigation, and auto‐fertilization functions are frequently used to deal with data scarcity issues (Nyeko, 2015; Samimi et al, 2020).…”

Historically, there has been a dispute over water allocation between users and policymakers in Iran's Zayandeh‐Roud Basin (ZRB). In this study, we used the “System of Environmental‐Economic Accounting for Water” (SEEAW) framework in combination with the hydrologic model “Soil and Water Assessment Tool” (SWAT) to achieve the water balance in ZRB. We used SEEAW to combine a wide range of water‐related statistics across stakeholders and SWAT to evaluate the unknown agricultural water use. The SWAT model is calibrated based on the stream flows and crop yields in the basin. The model assess the renewable water of the basin into two components, about 363 and 70 mm as green and blue water, respectively. Also results from the physical water supply and water use tables demonstrates that the agricultural sector uses 78% of the total renewable freshwater, followed by the residential, 16%, and the industrial sector, 6%. The flows of water from source to services in ZRB are traced based on the water supply and water use tables. The flow diagram shows that 8 MCM of industrial reused water was transferred to the agricultural sector, and 137 MCM and 18 MCM of water from the wastewater treatment plants to the agricultural and industrial sectors, respectively. Furthermore, the results show that the index of the basin dependence on groundwater resources is high (61%), the value of water stress is high (0.88) and the dependence of the basin on transboundary water resources is 30%. Therefore, this method is highly beneficial for achieving a conceptual water balance in disputed basins without enough agricultural water uses data.
