Factors determined amount of carbon sequestration in urban trees: a review

Abstract

Industrial Revolution and increased in population density lead to raise concentration of carbon dioxide in atmosphere from 280 ppm in 1850 and 380 ppm in 2005. This is due to abundance of carbon emitted from factories and vehicles. Since impact of carbon dioxide to global warming and climate change was identify, this situation really put this issue at high rank . To reduce carbon dioxide in the atmosphere, trees will help. The trees will sequester carbon during photosynthesis process and turn carbon into tissues in their body. This paper will review factors which determined amount of carbon uptake by urban trees from 1985 to 2013 studies. In summary, the factors that influenced increase of carbon sequesters by urban trees were tree size (diameter, height and crown cover), soil structure, tree species, climate and irrigation system. However, due to climate change that altered the rainfall patterns this will change the rate of carbon sequester by urban trees.
