Sustainability Assessment Model of the Buriganga River Restoration Project in Bangladesh: A System Dynamics and Inclusive Wealth Study

The Bangladesh government initiated the Buriganga River Restoration Project in 2010 to clean the heavily polluted Turag-Buriganga River. This study assessed the dynamic impact of the project on intergenerational well-being and developing a sustainable river system. The project outcomes were modeled for three future scenarios—varying waste control, streamflow, and migration control levels. System dynamics modeling—based on Streeter-Phelps’ water quality model and inclusive wealth (IW) index—was applied to secondary data (including remotely sensed data). The simulation model indicated that the project (with increasing streamflow up to 160 m3/s) will not ensure sustainability because dissolved oxygen (DO) is meaningfully decreasing, biological oxygen demand (BOD) is increasing, and IW is declining over time. However, sustainability can be achieved in scenario 3, an integrated strategy (streamflow: 160 m3/s, waste control: 87.78% and migration control: 6%) that will ensure DO of 8.3 mg/L, BOD of 3.1 mg/L, and IW of 57.5 billion USD in 2041, which is equivalent to 2.22% cumulative gross domestic product by 2041. This study is the first to use combined modeling to assess the dynamic impacts of a river restoration project. The findings can help policymakers to achieve sustainability and determine the optimal strategy for restoring polluted rivers.

Wealthier is healthier? Healthier is wealthier? A comprehensive econometric analysis of the European countries

Healthier people contribute more to the development of the economy. Besides, in a better economy, people have a better quality and healthier life. At this stage, one has to ask which one precedes the other: health or wealth? To find the answer, this study aims to investigate the causality relationship between health and inclusive wealth in the European countries for the period of 1990–2015. The causality between health and inclusive wealth scores, which are estimated by cluster and discriminant analyses, is investigated by the panel causality test. The research results indicate bidirectional causality between health and inclusive wealth. A one-way causality is detected in 11 cases as being from inclusive wealth to health and in 8 the other way. Furthermore, a two-way causality is found in 2 countries. Among the results, it is noteworthy that 91% of the countries with causality from inclusive wealth to health are among the healthy countries.

Conserving Economics for Biodiversity

The Economics of Biodiversity: The Dasgupta Review (Dasgupta 2021), henceforth the Review, tells us that we are embedded in Nature and our economies are bounded within Nature. It helps us estimate the value of natural capital and include it in estimations of economic output. The Review’s key messages concern (i) keeping our demands well within Nature’s supply, (ii) moving away from gross domestic product (GDP) towards inclusive wealth as a measure of economic success, and (iii) acknowledging the institutional failure in addressing global environmental problems and resolving them through institutional reforms in the financial and education systems. However, this commentary suggests that the Review is about conserving economics for biodiversity. It offers little opportunity for transformative change in our thinking and acting, to change our relationship with Nature so that we can conserve its diversity and dynamism...
