摘要:Rapid Urbanization in Bangladesh has created a negative im-pact 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 pol-lution. 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% vegeta-tion 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.
其他摘要:Hitra urbanizacija v Bangladešu je negativno vplivala na eko-sistem in posledično na podnebje. Območje preučevanja v tem članku je mesto Khulna (KCC). Glavni cilj te študije je predlagati izvedljive modele zelenih ulic za zmanjšanje onesnaženosti okolja. Predlagani so zeleni pasovi, ki zmanjšujejo vpliv škodljivih plinov in hkrati ohranjajo ekološko ravnovesje, kar prispeva k izpolnitvi 11. cilja trajnostnega razvoja. Članek ima tri dele. V prvem delu sta predstavljeni raziskava rabe in pokrovnosti tal ter raziskava javnega mnenja, izvedeni glede na sedanje stanje. Nato je predstavljen predlog sistema zelenih ulic na različnih križiščih, avtocestah in v soseskah mesta Khulna, ki temelji na nekaj uspešnih primerih. Nazadnje je predstavljen konceptualni okvir za izpolnitev 11. cilja trajnostnega razvoja. Iz raziskave je razvidno, da se je v zadnjih 20 letih vegetacija zmanjšala za 5 %. Prikazano je tudi, da je skupna količina ogljikovega dioksida (CO2), ki jo lahko sprejmejo velika drevesa po desetih letih, približno 32.000 kg na leto. Skupna količina CO2, ki jo lahko porabi grmičevje, je 34.810 kg na leto. Glede na raziskavo o zadovoljstvu uporabnikov je več kot 90 % ljudem všeč zamisel o zelenih ulicah, več kot 60 % pa jih meni, da bo uporaba ulic po ozelenitvi bolj praktična. Uspešno sprejetje zelenih ulic bo pripomoglo k doseganju za življenje prijetnih in zdravih skupnosti, mestno območje pa bo z izpolnitvijo 11. cilja trajnostnega razvoja postalo trajnostno.
