Survey results demonstrate the interconnected effect of natural and socio-economic conditions onthe coastal and upland ecosystem changes. When nature works negatively, it can severely affect the ecosystem and the socio-economic well-being of the people who depend on it. For instance, typhoons can wipe out gains from years of trying to reduce poverty, causing loss of life and damage to property and the environment. The effect of nature on the island’s ecosystem is noticeable in the landscape and farming system. The occurrence of climate-related disasters threaten the capacity of the environmentto provide food and livelihoods. In coastal areas, siltation and sedimentation severely affectcritical habitats to varying degrees with major implications for agricultural productivity, fish catches and human settlement.On the other hand, the effects of socio-economic changes on the ecosystem can be traced back to the1800s when the agro-ecological changes started from a position of abundance in agriculture and continued until production diminished and new areas were explored. Farming started with the “kaingin system” of plantation-based farming. Today, farming is characterized by permanent, diversified and specialized cropping patterns dominated by agro-forestry, root crops, corn and rice.In summary, nature, together with socio-economic pressures, has shaped and transformed the island’secosystem into what it is today. Reducing poverty and increasing people resilience are urgent requirements.It is therefore recommended that Local Government Unit (LGU)’s invest in manpower,resources and facilities for climate change adaptation, natural resource management and disaster risk reduction and management in their policy and development agendas.
