This is depicted by the increased incidence of environmental disasters, like floods, pollution, salt water-intrusion and a host of other destructive trends. Added to this, the very nature of its geographical setting makes the Philippines further vulnerable to the likely consequences of climate change. The Philippines is a humid tropical country, highly dependent on rainfall and its distribution for agricultural production. However, the present day variability of rainfall is very high with projected increase in the frequency of severe weather distortions like typhoons, floods, storm surges, and expected sea level rise. Equally vulnerable are the multi-purpose water reservoirs where sedimentation would be accelerated, thus escalating the cost of hydroelectric and irrigation dam management.
Flooding is brought about by intense precipitation.
Extreme dry conditions prevail during the dry season, especially, during El Nino Southern Oscillation episodes. Various studies have assessed the impacts of the changing climate on rice in the Philippines. Matthews et al. Studies have also shown that corn productivity would decline in the rain-fed areas in the Philippines. No estimates about the associated economic impacts have been made as yet.
