Through Congress and Inter-Congress meetings, and ongoing scientific Working Groups, PSA provides an interdisciplinary platform for scientists to discuss and review common concerns and priorities in the region. Through our scientific network, PSA links scientists from developed countries with those from developing countries, including the archipelagic and more remote states of the Pacific. PSA facilitates research initiatives on critical emerging issues for the region, such as biodiversity loss, climate change, infectious diseases, and the social implications of globalization, in which science can provide crucial information in a way that is required by both society and policymakers to make sound and informed decisions.
