- 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: This paper empirically assesses multidimensional energy poverty for low‐income households in South Africa using the four waves of the National Income Dynamics Study. The study adopts the Nussbaumer et al. (Measuring Energy Poverty, 2011) methodology, the multidimensional energy poverty index (MEPI), to estimate energy poverty on 10,801 low‐income households. The results indicate that low‐income households in rural areas are more energy deprived than those in the urban areas. The MEPI score across the years in low‐income urban and rural households depicts a moderate state of energy poverty. Furthermore, low‐income households in both the urban and the rural areas are mostly deprived in the dimension of heating fuel. The study recommends that suitable measures to combat energy poverty be rural–urban specific.

- Description: Evaluating the outcomes of wetland restoration projects is critical to improve practice and justify further investment in wetland restoration. We conducted a systematic literature review to evaluate the current state of knowledge on the economic valuation of the outcomes of wetland restoration. We assessed the economic methods applied, the attributes valued, and the timing of the evaluation in relation to the age of restoration along with publication trends. Research on the topic is increasing, but studies from Africa and South America are lacking. A diverse cross‐disciplinary interest is notable, yet collaborations between disciplines are less frequent. Of particular concern is that only a third of the studies were undertaken postrestoration, and even fewer for restorations older than 10 years. Gaps in the knowledge base mean that our present understanding of the value achieved through wetland restoration is tentative. The need for postrestoration site‐specific valuation efforts remains large both to justify further investment and to improve confidence in predictive and value transfer approaches as practical tools to inform decision‐making.

- Description: The transition to modern energy carriers like electricity is an important way to achieve to eradicate energy poverty. This study investigated energy transition patterns and trends in low-income South African households. The marginal effects of the different determinants on the probability of choosing a specific energy carrier were computed and the influence of some endogenous characteristics in transitioning to modern energy carriers was explored. It was found that energy ladder behaviour exists for cooking while energy stacking was most likely for space heating and the pattern for lighting tended towards energy stacking. Dwelling type, household size and geographical location were among the key determinants of the energy transition pattern. Policies to reduce energy poverty need a multi-pronged approach and not only a focus on electricity access.
