Ecological characteristics of the Philippines are influenced by its location within the Ring of Fire, such that it features volcanoes and fault systems. Moreover, the country lies along typhoon belts.
The Philippines has 7,100 islands, each with unique biotic assemblage. These form bioregions and biodiversity corridors based on geological history. The country is surrounded by archipelagic waters and has a coastline of 22,450 km. There are also distinct ecosystems and species diversity. Biodiversity is the foundation for healthy and functioning ecosystems.
Our terrestrial, freshwater and marine natural resources as well as plant and animal groups are diverse. Yet these are subject to numerous hazards and direct pressures from population concentration, growth, expansion, migration and consequent socio-economic activities.
GIS help to assess ecological conditions that are both threatened and are threats (an ecological hazard). Rich Philippine biodiversity and the socio-economic pressures threatening it heighten the urgent need to preserve these resources that the human community relies on. A conceptual flowchart of the mapping process is presented below:
