Purpose: Climate modification and population increase are threatening water supplies. The world's population have tripled ever since the turn of the century, nonrenewable energy demand has climbed by a ratio of 30, while occupational production had also risen by a ratio of 50. Theoretical Framework: Problem sizing and structure, model conceptualization, model implementation and testing, and scenarios analysis are the four phases of a conventional SD modeling framework. Methods: This indicates that as a result of occupational, agricultural, and urban usage, there is a rising demand for water and a diminishing supply of resources of sufficient quality. Due to the effects of climate change, unkind ocean smooth rose by 0.19 m among 1901 and 2010. Anthropogenic climate change is known to have impacted the incidence and magnitude of flooding. Globally, the recent identification of growing vogues in precipitation and large flows in specific basins suggests a larger impact. Results: This research article takes stock of the evaluation of the influences of climate change on water transport capacity, in particular using the Vensim model. In this research review, for the analysis or estimate of the impacts of climate change on the water transport capacity, Vensim was investigated using a system dynamics technique to simulate the basin slopes of the supply systems to study climatic effects. Conclusions: It was concluded that the combination of different adaptation strategies, such as desalination, the construction of dams and the promotion of water conservation, has the greatest effects in reducing the impacts of climate change.

Plastic packaging wastes are increasing due to the COVID-19 pandemic as consumers tend to stay home and purchase online. Plastic packaging waste is difficult to break down. It pollutes the environment and then enters the food chain, putting people and wildlife at risk. This paper presents the development of system dynamic models for sustainable plastic supply chain management in Klang Valley, Malaysia. System dynamic models for plastic supply chains, including forward, open-loop and closed-loop supply chains, were developed using Vensim 7.2 PLE software. To estimate the amount of plastic packaging wastes discharged at landfill, these models were simulated using various waste diversion rates. The results indicated that, when all stakeholders in the supply chain recycled 10% of their plastic packaging waste, the total amount of plastic packaging waste going to landfill could be reduced by approximately 65%. However, the means of open-loop and closed-loop supply chains, did not differ much.

Purpose: The purpose of this study is to address the growing challenges associated with water resources due to population growth, rapid economic expansion, and the imbalance between supply and demand. It aims to investigate the importance of water as a fundamental resource for ecological preservation and sustainable economic development. Design/Methodology/Approach: In this study, a comprehensive approach was taken to analyze water resources carrying capacity (WRCC) using the Vensim modeling tool. The research methodology involves considering the multifaceted roles of water resources within the complex ecological, environmental, societal, and economic systems, as well as their interrelationships with other system components. Findings: The findings of the study highlight the critical need for increasing investment in environmental protection and initiating new water storage projects to enhance the region's water resource carrying capacity. This research underscores the importance of sustainable water ecology in addressing the challenges posed by population growth and economic expansion. Research, Practical & Social Implications: This study has significant implications for research, practical applications, and societal well-being. It emphasizes the importance of understanding and managing water resources in a sustainable manner to ensure ecological health, economic development, and social progress. The findings can inform policy decisions and guide actions to address water resource challenges. Originality/Value: The originality and value of this study lie in its holistic approach to assessing WRCC and its consideration of the complex interactions between water resources, ecology, environment, society, and the economy. The research provides insights into the unique challenges faced by regions with increasing water resource demands and pollution and offers a modeling tool for measuring and enhancing water carrying capacity.
