Nexus Between Urban Green Streets and the Sustainability: Case on Khulna City Corporation (KCC) Area, Bangladesh

Abstract

Rapid Urbanization in Bangladesh has created a negative impact on the ecosystem and it’s resulting a change in the climate. In this research, Khulna City Corporation (KCC) is chosen to be the study area. The main objective of this study is to propose feasible models of green streets to reduce environmnetal pollution. Then it proposes green belts to alleviate the effect of harmful gases while maintaining ecological balance to achieve Sustainable Development Goals (SDGs) 11th goal. The study is completed in three phases. Firstly, Land Use Land Cover (LULC) detection and public opinion survey was conducted considering the existing scenario. Secondly, green street system was proposed in different intersection points, highways and neighborhoods of Khulna city on the basis of some successful cases and finally a conceptual framework for achieving SDG’s 11th goal is shown. This research shows that about 5% vegetation has decreased over the last 20 years. Also it shows the total amount of carbon-di-oxide (CO2) that can be consumed by big trees after 10 years is approximately 32,340 kg per year. The total amount of CO2 that can be consumed by shrubs is 34,810 kg per year. According to user satisfaction survey more than 90% people like the idea of green street and more than 60% people thinks that using the streets will be more convenient after its implementation. The successful adoption of green streets will help to achieve livable and healthy communities and also it will push the urban area towards sustainability by achieving SDG’s 11th goal.
