How Groundwater Impacts the People and Ecosystems of the South Pacific Islands - 2024 Darcy Lecture 2

Explore the critical role of groundwater in sustaining life across South Pacific Islands through this 56-minute Darcy Lecture delivered by Dr. Matthew Becker. Discover how groundwater systems function as lifelines for both human populations and delicate island ecosystems in this remote oceanic region. Learn about the unique hydrogeological challenges facing small island developing states, including saltwater intrusion, limited freshwater resources, and the vulnerability of groundwater supplies to climate change and sea-level rise. Examine case studies demonstrating how groundwater availability directly affects agricultural productivity, drinking water security, and the survival of endemic plant and animal species. Understand the interconnected relationships between groundwater, surface water, and coastal ecosystems, and how human activities can impact these fragile water systems. Gain insights into sustainable groundwater management strategies specifically designed for island environments, including monitoring techniques, conservation methods, and community-based approaches to water resource protection. Analyze the socioeconomic implications of groundwater scarcity and quality issues for island communities, and explore innovative solutions being implemented across the Pacific region to ensure long-term water security for both people and natural ecosystems.
