The practical importance of economic valuation information can hardly be overstated. Coastal and marine resource policy planning and management benefit from complete information on the impact of policy decisions. In addition, proper accounting of the impacts of these policy decisions is necessary for benefit-cost analyses and measurements of economic growth over time. This special issue focuses on economic valuation of coastal and marine ecosystem services. Economic valuation provides methods and techniques to determine how changes in coastal and marine ecosystem services can be translated into benefits and costs to society. Economic values play an important role in everyday life and provide useful information about human welfare and happiness. Valuation provides a consistent framework to understand human-nature interactions across a broad range of coastal and marine resources, and to evaluate the costs and benefits of these interactions. The focus on ecosystem services provides new research on this perspective of human-nature interactions that has profoundly changed the academic dialogue on natural systems, but has had limited impact on public dialogue and the policy process.

ECOLOGICAL ECONOMICS AND COASTAL ZONE ECOSYSTEMS' VALUES: AN OVERVIEW. Turner, R. K. , Bateman, I. J. and Adger, W. N. 1. 1 Coastal zone pressure and sustainable management challenges Given the continued intensification of the process of globalisation - involving population growth, population density changes via urbanisation, industrial development, increased trade and capital flows, liberalisation of transnational corporation activity and lifestyle and attitudinal changes - coastal zones and their hydrologically linked catchment areas have come under heavy environmental pressure. The scale and extent of socio-economic activities have profound implications for the now coevolving natural and human systems and their complex interrelationships (Turner, Perrings and Folke, 1997). The consequences of this process of change manifest themselves across a range of spatial and temporal scales. Indeed the juxtaposition of different spatial, functional and temporal scales that is inherent in the catchment-coastal ecosystems-seas/oceans continuum poses particularly difficult challenges for both science and resource management/governance.

This book applies the ‘ecosystem services’ framework to coastal environments, showing how it could facilitate an adaptive management strategy. The contributors describe a decision support system (DSS) based on the 3 Ps – pluralism, pragmatism and precaution – that leads to a more flexible, ‘learn by doing’ approach to the stewardship of coastal environments. The book lays out a “Balance Sheets Approach” to formatting, interrogating and presenting data and findings. The opening chapter defines coastal zones, their characteristics and natural resources, and describes their complex and dynamic nature. The chapter shows that large-scale trends and pressures have led to a global loss of 50% of marshes, leading to significant declines in biodiversity and habitat. Part I presents a conceptual framework, describes natural science techniques for coastal and shelf modeling, and describes valuation of ecosystem services. Part II outlines practical ecosystem indicators for coastal and marine ecosystem services, reviews literature on valuation of coastal and marine ecosystem services, explores scenarios, outlines marine and coastal ecosystem services data and offers tools for incorporating data into decision-making. PART III offers case studies including one linking the ecosystem services of Marine Protected Areas to benefits in human wellbeing; and another on valuing blue carbon captured by oceans and coastal ecosystems. Also included are a study of managed realignments and the English coastline and their value estimate transferability; and studies of the impact of jellyfish blooms on recreation in the UK and on fisheries in Italy.

Marine and coastal resources provide millions of people with their livelihoods, such as fishing and tourism, and a range of critical additional ‘ecosystem services’, from biodiversity and culture to carbon storage and flood protection. Yet across the world, these resources are fast-diminishing under the weight of pollution, land clearance, coastal development, overfishing, natural disasters and climate change. This book shows how economic instruments can be used to incentivize the conservation of marine and coastal resources. It is shown that traditional approaches to halt the decline focus on regulating against destructive practices, but to little effect. A more successful strategy could be to establish schemes such as payments for ecosystem services (PES), or incorporate an element of financial incentives into existing regulatory mechanisms. Examples, both terrestrial and marine, from across the world suggest that PES can work to protect both livelihoods and environments. But to succeed, it is shown that these schemes must be underpinned by robust research, clear property rights, sound governance structures, equitable benefit sharing, and sustainable finance. Case studies are included from south and east Asia, Latin America, Africa and Australia. The book explores the prospects and challenges, and draws lessons from PES and PES-like programmes from across the globe.

On April 20, 2010, the Deepwater Horizon platform drilling the Macondo well in Mississippi Canyon Block 252 (DWH) exploded, killing 11 workers and injuring another 17. The DWH oil spill resulted in nearly 5 million barrels (approximately 200 million gallons) of crude oil spilling into the Gulf of Mexico (GoM). The full impacts of the spill on the GoM and the people who live and work there are unknown but expected to be considerable, and will be expressed over years to decades. In the short term, up to 80,000 square miles of the U.S. Exclusive Economic Zone (EEZ) were closed to fishing, resulting in loss of food, jobs and recreation. The DWH oil spill immediately triggered a process under the U.S. Oil Pollution Act of 1990 (OPA) to determine the extent and severity of the "injury" (defined as an observable or measurable adverse change in a natural resource or impairment of a natural resource service) to the public trust, known as the Natural Resources Damage Assessment (NRDA). The assessment, undertaken by the trustees (designated technical experts who act on behalf of the public and who are tasked with assessing the nature and extent of site-related contamination and impacts), requires: (1) quantifying the extent of damage; (2) developing, implementing, and monitoring restoration plans; and (3) seeking compensation for the costs of assessment and restoration from those deemed responsible for the injury. This interim report provides options for expanding the current effort to include the analysis of ecosystem services to help address the unprecedented scale of this spill in U.S. waters and the challenges it presents to those charged with undertaking the damage assessment.

The Little Green Data Book is a pocket-sized ready reference on key environmental data for over 200 countries. Key indicators are organized under the headings of agriculture, forestry, biodiversity, oceans, energy, emission and pollution, and water and sanitation. For the second year, The Little Green Data Book presents a new set of ocean-related indicators, highlighting the role of oceans in economic development.

Nutrient recycling, habitat for plants and animals, flood control, and water supply are among the many beneficial services provided by aquatic ecosystems. In making decisions about human activities, such as draining a wetland for a housing development, it is essential to consider both the value of the development and the value of the ecosystem services that could be lost. Despite a growing recognition of the importance of ecosystem services, their value is often overlooked in environmental decision-making. This report identifies methods for assigning economic value to ecosystem servicesâ€"even intangible onesâ€"and calls for greater collaboration between ecologists and economists in such efforts.
