- Description: Modern day societies and economies are becoming increasingly vulnerable to the continued erosion of the stocks and flows of essential ecosystem services. Thus, the management of complex socio-economic systems to effectively provide these essential services has become a global priority policy and academic research area. Understanding how underlying processes and functions contribute towards the provision of final ecosystem services can facilitate improved dissemination of credible, legitimate and salient information to decision-makers. This paper presents an ecosystem service value chain analysis framework that applies basic system dynamics modelling in the form of causal loop diagrams to facilitate an alternative analysis of ecosystem service value chains. A scoping application of the framework is applied to a case study for flood attenuation services in the Baviaanskloof catchment in South Africa. The framework enables the identification of forward linkages and ripple effects in individual value chains of final ecosystem services as well as the identification and assessment of challenges and opportunities within individual causal pathways. Ultimately, providing the potential to advance strategies for improving the efficiency and effectiveness of final ecosystem service provision.

- Description: We still have a limited understanding of the value chains, markets and the actual economic value of ecosystem services from aquat-ic ecosystems. Different studies have developed various ap-proaches for determining the economic value of these benefits, and of the associated natural capital. Most confirm that the value of aquatic ecosystems lies in the sustained nett benefits derived from the many ecosystem services they supply; including various ecological functions, products for direct and indirect human con-sumption, energy, aesthetic and recreational benefits, and assimi-lative capacity of the residues of human activities. However, the geographic, cultural and economic differences between countries or nations have resulted in different views that affect the market potential of ecosystem services from aquatic ecosystems. This study focused on identifying key ecosystem services and their forward linkages, understanding how to improve market access to such services, and creating or improving the value chains in the South African context. The research is intended to help identify opportunities for improvements that benefit society more broadly. It is anticipated that the study will be useful to land use planners, designers of infrastructure and town planners.
