摘要

Water is a critical resource, and the shortage of freshwater resources worldwide will only become more critical as the world population increases and climate changes. The management of water resources provides a myriad of challenges, and, in light of advances in science, technology and policy making, now requires an integrated approach to be successful. Eutrophication and algal blooms are one of the most common and serious threats to the safety and security of water resources; however, despite advances in science and policy, the socio-economic consequences of the impact of such events on systems are still not well known. The economic cost of managing water quality issues is enormous, and can only benefit from the development of more integrated water management strategies. Research into areas related to water resources, such as management, policy, non-point source pollutants, wastewater, nutrients and water quality has increased significantly over the past 20. years, and will continue to increase as stakeholders and managers strive to develop more environmentally, socially, and economically sustainable water resource management plans. This perspective paper also presents a summary of a selection of research that formed part of the deliberations of the International Symposium on Science, Technology and Policy for Water Pollution Control at the Watershed Scale, held in April 2009.
