This particular title reviews the country’s natural resource and environmental problems across ecosystems, per ecosystem, and per critical resource. It also presents a history of natural resources and environmental laws and policies, with the Philippine Agenda 21 (PA 21) highlighted, and discusses some of the important gaps and issues. While the implementation of PA 21 may be behind schedule, this book argues that a determined effort to address the most pressing issues will hasten the attainment of a more sustainable form of development for the country.
