Mangrove forests are among the most sensitive and also the most threatened ecosystems on Earth. At the same time, nearly all of them are located in regions where food security is fragile and smallholder families are desperate to find additional sources of income. As a result, the local population views them as a resource for enhancing their livelihoods; and as there are significant differences between the private profitability of converting mangroves into farm land and the social cost-benefit-balance of such actions, conflicts between the protection of mangrove forests on the one hand and their use for agricultural production on the other hand are prevalent. This study was conducted to estimate the economic value of the Wunbaike Mangrove and to evaluate the benefits of the alternative mangrove uses from the private and social point of view to assist in the improvement of mangrove management strategies and policies. The study focused on the Wunbaike Mangrove users in the Yanbye Township. The economic value of mangroves was estimated in terms of local direct use of mangrove forest products and users’ willingness to pay for the conservation of mangroves for its non-use value. Financial and economic cost-benefit analyses were conducted to evaluate the rice and shrimp farms in the mangroves.
In Vietnam, mangrove forests have been threatened by economic pressures and climate change. This report aims to analyze both opportunities and constraints for mangrove protection and management in Vietnam.The study found that local people appreciate the role that mangroves play in providing income, an attractive landscape and shelter from climate change related floods and storms. Many communities would be willing to contribute between USD 2-20 per year to a trust fund so as to protect their forests. A large number of policies and projects promote mangrove conservation activities. This has helped strengthen law enforcement, raised local awareness of the role and importance of maintaining forests, and restricted the conversion of mangroves to other economic activities. Government policies and development projects also provide capacity building, training and seedlings for mangrove reforestation activities at the studied sites. Additionally, new incentives such as payment for forest environmental services (PFES) are emerging as a potential source of finance to support mangrove protection and development in the future. Collective action for mangrove protection is widely recognized and promoted among study sites. People have self-organized strikes and protests to oppose converting mangroves to other economic purposes.Many policies and projects offer social and economic incentives for mangrove protection. However, they are impeded by insecure tenure, land grabbing, elite capture, inequitable benefit-sharing, and unclear responsibilities among government agencies at central, provincial and multilateral levels. Access to information on both policies and projects is difficult for local people. The monitoring and evaluation systems, incentives and disincentives designed by policies and projects have low enforcement and compliance. Policies and projects strongly emphasize and create incentives to replant mangrove forests, rather than to maintain and conserve existing mangrove forest areas. Incentives are also designed to compensate local labor costs for replanting mangrove or patrolling activities, rather than addressing the direct drivers of deforestation and degradation.Protecting mangroves requires a policy shift in land-use planning to address the drivers of mangrove deforestation and degradation. These drivers, in turn, respond to national and provincial economic development agendas, which focus on aquaculture expansion and migration. Cross-sectoral coordination also needs to be further enhanced to improve effectiveness in law enforcement. Enhancing local participation in mangrove forest protection and development requires a gender-sensitive approach and enabling conditions, such as well-enforced policies, accountable and transparent benefit-sharing, and inclusive decision making.

"This atlas provides the first truly global assessment of the state of the world's mangroves. Written by the leading expert on mangroves with support from the top international researchers and conservation organizations, this full color atlas contains 60 full-page maps, hundreds of photographs and illustrations and a comprehensive country-by-country assessment of mangroves. Included are the first detailed estimates of changes in mangrove forestcover worldwide and at regional and national levels, an assessment of these changes and a country-by-country examination of biodiversity protection. The book also presents a wealth of global statistics on biodiversity, habitat area, loss and economic value which provide a unique record of mangroves against which future threats and changes can be evaluated. Case-studies, written by regional experts, provide insights into regional mangrove issues, including primary and potential productivity, biodiversity, and information on present and traditional uses and values and sustainable management."--Pub. desc.
Human well-being relies critically on ecosystem services provided by nature. Examples include water and air quality regulation, nutrient cycling and decomposition, plant pollination and flood control, all of which are dependent on biodiversity. They are predominantly public goods with limited or no markets and do not command any price in the conventional economic system, so their loss is often not detected and continues unaddressed and unabated. This in turn not only impacts human well-being, but also seriously undermines the sustainability of the economic system. It is against this background that TEEB: The Economics of Ecosystems and Biodiversity project was set up in 2007 and led by the United Nations Environment Programme to provide a comprehensive global assessment of economic aspects of these issues. This book, written by a team of international experts, represents the scientific state of the art, providing a comprehensive assessment of the fundamental ecological and economic principles of measuring and valuing ecosystem services and biodiversity, and showing how these can be mainstreamed into public policies. This volume and subsequent TEEB outputs will provide the authoritative knowledge and guidance to drive forward the biodiversity conservation agenda for the next decade.
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.
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.
