Teak trees computational modelling to measure environmental contribution using functional-structural plant modelling

Teak trees (Tectona grandis) are known for their excellent and expensive wood quality. However, teak trees have many contributions to the environment, such as maintaining soil stability and preventing erosion. Teak leaves also make an environmental contribution, namely producing oxygen and absorbing carbon. This study aims to create a plant computational model of teak trees using the functional-structural plant modelling (FSPM) method which is implemented on the growth grammar-related interactive modelling platform (GroIMP). This model can simulate the growth of teak trees morphologically and predict the contribution of teak trees to the environment such as the total oxygen produced, and the carbon absorption. The model simulated that one teak tree at the age of 20 can produce 1,800 grams of oxygen per day and absorb 670 grams of carbon per day, providing enough oxygen for three people in one day.
