Establishment of marine managed areas (MMAs) is a long-term investment in secure and sustainable ecosystems—secure for the people that depend on them for sustenance and livelihoods, sustainable in terms of the long-term persistence of habitats and species present.

One approach to the development of better coastal and marine policy and management is the concept of marine managed areas (MMAs). A MMA is an area of ocean, or a combination of land and ocean, where all human activities are managed toward common goals. MMAs are a form of ecosystem-based management, where all elements—biophysical, human, and institutional—of a particular system are considered together. This document describes what MMAs are, why they are important, and where they are implemented.

Although much research has been done on the ecological benefits and challenges of marine resource management, comparatively little insight has been gained into the benefits and challenges of the human well-being aspects. This document addresses this gap by building on existing knowledge and synthesizing over 20 social science studies conducted over the past five years in 19 countries, involving over 35 scientists, and drawing on experiences in 52 marine managed areas (MMAs) worldwide.

Conceptual diagrams are an excellent means of providing synthesis, visualization, and appropriate context to science communication, an essential component of environmental problem solving. The creation of conceptual diagrams provides an interface for engagement of various stakeholders, including scientists, managers, and wider public partners.

Vast areas of the globe's coastal zone have experienced significant declines in ecosystem health. Deteriorating water quality, loss and alteration of vital habitats, and reduced populations of fish and shellfish are some of the major changes recorded. Establishing and running an effective assessment program is a complex process that necessitates strategic collaboration and partnerships between many individuals and agencies.

Although spatial analysis is technically a component of statistical analysis and environmental modeling, the important role it plays, or should play, in coastal assessment programs warrants specific attention in its own separate chapter. This chapter provides some of the basic principles for producing effective maps through to the process of undertaking complex spatial analyses.

In this chapter, we describe the logistics of designing a monitoring program to obtain data within an integrated coastal assessment framework. We begin with the challenge of explicitly defining program goals and objectives, and describe the role of conceptual models and diagrams in facilitating this process. We next describe the selection of a subset of physical and chemical indicators for monitoring ecosystem status and trends.

As highlighted in the title of this chapter, the array of in situ instruments available for coastal monitoring is increasing rapidly, "the ever-growing toolbox,"(Figure 12.1). This growth is driven in part by research and development into new or existing sensors, sensor platforms, data logging, and data telemetry.

A coastal assessment program cannot simply draw from a few individuals; it takes contributions from an entire community and the creation of a shared vision. Keeping a balance among research, monitoring, and management is especially important and includes the dynamics of human interactions and strong communication between stakeholders and the broader community.

For every environmental campaign, a strong leader is needed for guidance and motivation. There have been a series of leaders or "champions" in the history of the world who have changed life on this planet. All of these leaders, no matter what area their specialty, have contained the following traits: knowledge of their field; passion for what they do; and an ability to successfully communicate their messages not only to their colleagues, but also to the broader community.
