Carbon Budgets of Forest Ecosystems in the Philippines
... The rapid loss of forests in the Philippines has left millions of hectares of denuded and degraded lands (FMB 1998). This has resulted to loss of huge amount of carbon that is stored in the natural forests. As has been discussed earlier, deforested lands have much lower C density than the forests th ...
