4、 demand of 14 cubic meters per plant(based on a mix of 30 percent trees and 70 percent shrubs of varying species,age groups,and irrigation needs),the estimated total water demand in 2025,2030,and once all 10 billion trees have been planted is 1.424 billion cubic meters per year,8.545 billion cubic m

5、eters per year,and 142.423 billion cubic meters per year respectively.There are several sustainability strategies that can help make the SGI goals achievable.The first is to focus on planting native,drought-tolerant,non-invasive plants,such as the Manila tamarind shrub and the Arak tree.Next,target
