Exploring the influence of regime shifts on ecosystem services in Iran’s Zayandeh-Rud river basin

Abstract

ABSTRACT This research delves into the impact of human-induced regime shifts on ecosystem services in Iran’s Zayandeh-Rud River Basin, during the onset of the Anthropocene epoch marked by rapid changes attributed to human activities. Employing network analysis techniques, including in-degree and out-degree centrality, pivotal actors or drivers contributing to these shifts were identified. A total of 43 experts and researchers in humanities and environmental sciences completed questionnaires to assess the relationship network of regime shift drivers within the river basin, revealing the significant influence of governmental administration, water transfer projects, and water allocation. These factors were found to drive regime shifts, subsequently impacting environmental well-being. The study also thoroughly analyzed the ecosystem services and factors affecting human and environmental welfare affected by these shifts. Insights gained from this research offer crucial information for the development of effective management strategies and policies aimed at mitigating and adapting to regime shifts. By highlighting the key drivers and their impact on ecosystem services, the research provides actionable strategies for addressing regime shifts in the study area. Ultimately, this study contributes to a deeper understanding of the intricate interplay between human activities, regime shifts, and environmental well-being, essential for informed decision-making and sustainable management practices.
