Marine spatial planning (MSP) has been underway in Western European countries for almost a decade. Belgium, The Netherlands, Germany, and Norway are already working on second-generation spatial plans for their marine areas in the North and Baltic seas. Other countries, including the United States, Canada, the United Kingdom, and Sweden are working...
Chapter

This chapter introduces marine/maritime spatial planning (MSP) from the perspective of research and practice. After providing some basic definitions and terminology, it shows how MSP has developed since its inception, ending with a description of its current status of adoption around the world. It also sets out how MSP has been received in various...
Article
This paper reviews the key developments of ocean management leading up to and over the past decade, especially marine or maritime spatial planning and ecosystem-based management, with an emphasis on the former. From scattered seeds in a few marine places—from early marine spatial analysis and data atlases to the EU Marine Spatial Directive in 2014—...
Article

The acceleration of global warming and increased vulnerability of marine social-ecological systems affect the benefits provided by the ocean. Spatial planning of marine areas is vital to balance multiple human demands and ensure a healthy ocean, while supporting global ocean goals. To thrive in a changing ocean though, marine spatial planning (MSP)...
Chapter
Full-text available
This chapter provides an overview on the current status of MSP, starting by addressing what MSP is and why is it needed. It then reviews the global distribution of MSP around the world and, finally, analyses some of the most prominent and widespread challenges, present and future, that are linked to the development of MSP.

This guide on performance monitoring and evaluation (evaluation) is intended for practitioners responsible for planning and managing marine areas. Practitioners are the managers and stakeholders who are responsible for designing, planning, implementing, monitoring, and evaluating marine management plans. While its focus is on the performance monito...
Article
Full-text available
Evidence-based decision making is an essential process for sustainable, effective, and efficient marine spatial planning (MSP). In that sense, decision support tools (DSTs) could be considered to be the primary assistant of planners. Although there are many DSTs listed in tool databases, most of them are conceptual and not used in real MSP implemen...

Driven by outside economic forces and the effects of climate change, the Arctic, its ecosystems, and its people are all faced with substantial change ranging from the loss of ice-dependent species, more intense human uses of the Arctic, and the loss of natural services provided by Arctic ecosystems. In addition to business opportunities, these chan...
