Marine Sciences and Society Despite repeated attempts to improve ocean management, human activities have led to significant degradation of ocean ecosystems. Experts have concluded that this failure is attributable in large part to the traditionally balkanized approach to ocean management. Each activity – such as fishing, shipping, oil and gas development, and renewable energy production -- is governed by a different set of laws and administered by a different agency. Scientists, policy experts, and governments are turning to the emerging practice of marine spatial planning as a practical way to implement ecosystem-based ocean management. This approach requires managers and stakeholders to assess and allocate access to ocean resources within a given area in a way that minimizes conflict and maximizes the potential to achieve ecological, economic, and social objectives. Speakers will explore the latest developments in the science, policy, and practice of marine spatial planning especially in light of a U.S. presidential memorandum directing all federal agencies with jurisdiction over activities that affect the oceans to develop a “framework for effective coastal and marine spatial planning” that “addresses conservation, economic activity, user conflict, and sustainable use of ocean, coastal, and Great Lakes resources.”
