The impact of climate change-related hazards in Papua New Guinea (PNG) has been increasing in intensity and frequency. Tropical storms and cyclones have become more common and further impacts from climate change include the loss of food gardens (widely used for subsistence farming) due to extensive flooding (both in coastal and riverine areas) combined with extended periods of drought. The rising sea level is causing the gradual submersion of some of PNG‘s islands. In addition, saltwater intrusion is lowering clean groundwater levels and loss of freshwater, particularly on islands and in coastal areas. This, too, poses a challenge for innovative agricultural expansion. In the highlands, increasing hailstorms and frost events have destroyed gardens used for subsistence farming. Irregular rainfall patterns with periods of prolonged dry seasons affect soil fertility and yield while increasing the spread of infectious diseases and pests, which are further decreasing agricultural productivity and producing food shortages in some areas of the country. With this drastic onset of climate change impacts, the country is increas
The programme strategy focuses on implementing measures as well as building institutional and policy capacities that promote efficient and cost-effective adaptation to coastal and inland flood- related risks at the sub-national levels. Community level-interventions will address specific vulnerability characteristics of two distinct geographic areas: the Northern coastal regions and island provinces, which face coastal flooding risks, as well as the river communities in the North Coast Region that are exposed to inland flooding.
