Analysis of Social-Ecological System: Nakdong River Ecosystem Services
This paper delves into the social-ecological system of the Four Major Rivers Project in Iceland, focusing on the resilience improvement plan with an emphasis on the ecosystem services provided by the Nakdong River. Presented by Kihwan Song and Jinhyung Chon from Korea University, along with Nam-Hee Choi from Korea National University of Transport. Dive into the insightful analysis from this conference session.

THE 36TH INTERNATIONAL CONFERENCE OF THE SYSTEM DYNAMICS SOCIETY REYKJAV K, ICELAND Analysis of the Social-Ecological System of the Four Major Rivers Project and Resilience Improvement Plan with a Focus on the Ecosystem Services of the Nakdong River Kihwan Song, Korea University Jinhyung Chon, Korea University Nam-Hee Choi, Korea National University of Transport 0:00-0:30
Problem Statement Ecosystem services problem Provisioning services: agriculture/industrial water Regulating services: algal bloom Cultural services: ecotourism Supporting services: destruction of ecosystems The purpose of this study to identify the change of ecosystem service resilience through analysis of social-ecological system in the Nakdong River area and to suggest resilience improvement plan using the resilience principle. 0:30-2:00
Approach or Dynamic Hypothesis Classification of ecosystem services in the Nakdong River area and key variables Section Subsection Contents Fish and shellfish Animals and plants, dietary fiber Key variable Fishery production Crop and livestock production Water discharge Quantity of water intake Water for living, industrial water, agriculture water Hydroelectric power generation facility Hydroelectric power generation amount Amount of use Energy production amount using biomass Evapotranspiration per day/month Water temperature Average storage Mean velocity of flow Residence time Water purification index animals and plants Attached algae species and population amount Emerged plant Flood prevention facility Flood frequency Ecotourism destination designation Participation Jogging, bicycle exercise, fishing, swimming, etc. Waterfront park utilization Festival events Ecological Landscape Protected Area designation River geomorphological landscape Cultural properties designation Watershed or sphere area Natural ecosystem area Fish endemic species Vegetation distribution Riparian vegetation diversity Food Freshwater Direct use Provisioning services Hydroelectric power generation Biotic and abiotic energy sources Energy Biomass energy source Climate regulation Microclimate regulation Water purification function by flow or velocity Regulating services Pollutant self- purification capacity Water purification Water purification capacity Disaster regulation Flood, drought, forest fire prevention and mitigation Ecotourism River ecotourism Cultural services Rest/leisure Hydrophile property act and space utilization Landscape aesthetics Visual landscape Religious Identity Habitat Ecosystem support through habitat continuity Supporting services Biodiversity Diversity of species or population 2:00-3:30
Progress and Insights to Share Analysis of a causal loop diagram and resilience of ecosystem services in the Nakdong River area Regulating service Supporting service Cultural service Provisioning service Resilience improvement plan for ecosystem services in the Nakdong River area Diversity and redundancy / Connectivity / Slow variables and feeedbacks 3:30-5:00
