Cost Benefit Analisys of Urban Tree Management in Goiânia
Previous studies have shown the benefit value of isolated trees. However, only a few studies establish a relation among various benefits and various trees. Uncertainty is the word that better defines urban tree management projects, what should a do, how much it will cost, how big the scope should be, when benefits will come. Welfares can be easily enumerated but hard to measure. This fuzzy scenario is frequently a barrier to project approval. Many projects proposals fail on showing how will contribute to institution, losing, consequently, the resources competition to other projects or investments.
