IYM aims to ensure the well-being of the mountain populations by promoting sustainable development in the mountains. It is consistent with Agenda 21, the global blueprint for sustainable development of 1992 Earth Summit in Rio de Janeiro, classifying mountains in the same order of importance as other global environmental concerns.
Mountains are stupendous landmasses rising in different altitudes and with varied shapes and sizes. In our country, they are homes of more than eight million Filipinos who depend on its natural resources for survival. These people are commonly called upland dwellers. They used to practice "kaingin" or slash and burn as agricultural method destroying the forest cover. As such, they were the major factor in forest destruction. With the paradigm shift of DENR in managing them, this practice was greatly minimized, if not totally put to a halt. Former kaingineros are now partners in forest development through community-based projects.
