Oxygen Generation by Dominant Urban Trees: A Case Study from Konnagar Municipality, West Bengal, India
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 1
Abstract
Urban vegetation, particularly trees provides a wide spectrum of ecosystem services which include upgradation of air quality, stabilizing temperature, reduction in ultraviolet radiation, oxygen generation, carbon sequestration, habitat of several flora and fauna (enhancement of biodiversity) aesthetic beauty etc. Oxygen production is one of the most commonly cited benefits of urban trees. The purpose of this article is to estimate the oxygen production by the dominant trees in the urban area of Konnagar, compare it with the estimated oxygen consumption by the population of the area and illustrate why oxygen production by urban trees is an important ecosystem service. Net oxygen production by trees is a function of the amount of oxygen produced during photosynthesis minus the amount of oxygen utilized during respiration [1]. If the carbon dioxide uptake during photosynthesis exceeds carbon dioxide release by respiration during the year, the tree will accumulate carbon (carbon sequestration). Thus, a tree that has a net accumulation of carbon during a year (tree growth) also has a net production of oxygen. This net production of oxygen is estimated as per the following expression Net O2 release (Kg/yr) = Net C sequestration (Kg/yr) ×32/12 The entire methodology of estimating oxygen production conducted during 2016 involved four phases.
