More than half the world population lives in the Asia-Pacific region. As a result there is a large pressure on the natural resources of the region. There are widespread concerns about the quality of the environment, ranging from the consequences of climate change on food security and sea-level rise, to loss of biodiversity in marine terrestrial ecosystems and the degradation of land and water resources. Other areas of concern in the Asia-Pacific region relate to the management and mitigation of natural disasters, the occurrence of widespread and persistent poverty, poor education and health care facilities in rural areas, poor physical and communication infrastructure, etc.
