The Benefits to People of Expanding Marine Protected Areas

This study focuses on how the economic value of marine ecosystem services to people and communities is expected to change with the expansion of marine protected areas (MPAs). It is recognised, however, that instrumental economic value derived from ecosystem services is only one component of the overall value of the marine environment and that the intrinsic value of nature also provides an argument for the conservation of the marine habitats and biodiversity

Marginal Abatement Costs of Carbon-Dioxide Emissions: A Meta-Analysis. ESRI WP248, June 2008

In this paper we carry out a meta-analysis of recent studies into the costs of greenhouse gas mitigation policies that aim at the long-term stabilization of these gases in the atmosphere. We find the cost estimates of the studies to be sensitive to the level of the stabilization target, the assumed emissions baseline, intertemporal optimisation, the choice of control variable (CO2 only versus multigas), assumptions on future technological options (backstop and carbon capture and storage), and, to a lesser degree, the scientific “forum” in which the study was developed

The environmental benefits of investment in agricultural science and technology: an application of global spatial benefit transfer

Food security is a major current and future policy concern. The world population is projected to reach 9 billion by 2050 and continuing growth in economic output and incomes is expected to result in changing food consumption patterns. In particular the wider adoption of ‘Western’ diets will result in both higher calorie intake and greater meat consumption. Continuing climate change is expected to add further pressures to agricultural production. This paper presents the results of a global analysis funded by the TEEB study on the environmental benefits of investment in agricultural knowledge, science and technology, specifically in terms of closing the gaps between developing and developed country agricultural productivity. The results show that by easing pressures on land use change on terrestrial biomes (forests and grasslands), and the ecosystem services they provide, investment in agricultural science and technology provides environmental benefits of US$161.3bn per annum in 2050. Between 2000 and 2050 these benefits amount to US$2,964bn in addition to US$6,343bn in carbon benefits and compare to costs of US$5,68bnResearch and Development/Tech Change/Emerging Technologies,

Impact of climate events, pollution, and green spaces on mental health: an umbrella review of meta-analyses

Climate change may affect mental health. We conducted an umbrella review of meta-analyses examining the association between mental health and climate events related to climate change, pollution and green spaces. We searched major bibliographic databases and included meta-analyses with at least five primary studies. Results were summarized narratively. We included 24 meta-analyses on mental health and climate events (n = 13), pollution (n = 11), and green spaces (n = 2) (two meta-analyses provided data on two categories). The quality was suboptimal. According to AMSTAR-2, the overall confidence in the results was high for none of the studies, for three it was moderate, and for the other studies the confidence was low to critically low. The meta-analyses on climate events suggested an increased prevalence of symptoms of post-traumatic stress, depression, and anxiety associated with the exposure to various types of climate events, although the effect sizes differed considerably across study and not all were significant. The meta-analyses on pollution suggested that there may be a small but significant association between PM2.5, PM10, NO2, SO2, CO and mental health, especially depression and suicide, as well as autism spectrum disorders after exposure during pregnancy, but the resulting effect sizes varied considerably. Serious methodological flaws make it difficult to draw credible conclusions. We found reasonable evidence for an association between climate events and mental health and some evidence for an association between pollution and mental disorders. More high-quality research is needed to verify these associations

Capturing Malagasy fisher communities non-market economic values using mixed methods

Understanding how people value ecosystem goods and services can provide important information to managers and planners. Marine protected area valuations often focus on marketed goods and services. For many traditional fisherfolk, however, non-marketed ecosystem services are critically important inputs to their wellbeing. Using discrete choice experiments (DCEs), we quantify the values that Vezo fisherfolk of southwestern Madagascar place on three non-marketed services: (1) the likelihood that their offspring will be able to follow their parents livelihoods as traditional fishers (bequest value); (2) increased social cooperation between villages (social capital); and (3) storm protection. The DCE was conducted in 2010 as part of a comprehensive Total Economic Valuation (TEV) of ecosystem services flowing from a community-managed marine area in southwest Madagascar. The TEV includes provisioning (fisheries, wood, shells, freshwater, medicinal plants, research, and tourism), regulating (organic waste disposal, carbon sequestration, and storm protection), and cultural ecosystem services (social capital represented by levels of intervillage cooperation and respect and intravillage conflict about marine resource use; cultural heritage represented as a bequest value; education; recreation; and spiritual). We present values for all ecosystem services measured in the valuation, along with interpretations of differences between groups and methods. We triangulate a number of the values using multiple methods, including market-based, ranking and rating, and Likert-scale rating. Despite their reputation in the academic literature as “living for each day”, we find that bequest values constitute an important portion of the total value that local Vezo fisherfolk place on the environment.Keywords: Fisheries Economics, Measurement and Indicators for Improved Management and Understanding Part I, Modeling & Economic Theor

Global socio-economic impacts of changes in natural capital and ecosystem services:State of play and new modeling approaches

The year 2020 is a critical year for sustainable development policy and practice with the review and renewal of various international commitments including the Sustainable Development Goals, the Convention on Biological Diversity and the Paris Agreement. The post-2020 agenda needs to be informed by more robust analytical approaches that capture the interactions between the economy, society and the environment. In this paper, we review the state of the art in available models and datasets that lay the groundwork for future analytical work to inform this agenda. Based on this review, we propose an integrated modeling approach for global analysis to underpin international policy discourse and advocacy, and; a sub-global approach focusing on evaluating specific strategies and policy portfolios to make progress toward sustainability commitments considering detailed local country context. Both approaches rely on integrating whole of economy computable general equilibrium models with spatial land use land cover and ecosystem services models. Endogenizing feedbacks between modeling system components ensures that evidence is based on interactions between all system components. Recent advances in methods, data and available tools discussed herein reduce barriers to entry for this type of complex systems analysis and increases the timeliness of policy advice

The global costs and benefits of expanding Marine Protected Areas

Marine ecosystems and the services they provide contribute greatly to human well-being but are becoming degraded in many areas around the world. The expansion of Marine Protected Areas (MPAs) has been advanced as a potential solution to this problem but their economic feasibility has hardly been studied. We conduct an economic assessment of the costs and benefits of six scenarios for the global expansion of MPAs. The analysis is conducted at a high spatial resolution, allowing the estimated costs and benefits to reflect the ecological and economic characteristics and context of each MPA and marine ecosystem. The results show that the global benefits of expanding MPAs exceed their costs by a factor 1.4–2.7 depending on the location and extent of MPA expansion. Targeting protection towards pristine areas with high biodiversity yields higher net returns than focusing on areas with low biodiversity or areas that have experienced high human impact

Improving air quality in metropolitan Mexico City : an economic valuation

Mexico City has for years experienced high levels of ozone and particulate air pollution. In 1995-99 the entire population of the Mexico City metropolitan area was exposed to annual average concentrations of fine particulate pollution (particulates with a diameter of less than 10micrometers, or PM10) exceeding 50 micrograms per cubic meter, the annual average standard in both Mexico and the United States. Two million people were exposed to annual average PM10 levels of more than 75 micrograms per cubic meter. The daily maximum one-hour ozone standard was exceeded at least 300 days a year. The Mexico Air Quality Management Team documents population-weighted exposures to ozone and PM10 between 1995 and 1999, project exposures in 2010, and computes the value of four scenarios for 2010: A 10 percent reduction in PM10 and ozone. A 20 percent reduction in PM10 and ozone. Achievement of ambient air quality standards across the metropolitan area. A 68 percent reduction in ozone and a 47 percent reduction in PM10 across the metropolitan area. The authors calculate the health benefits of reducing ozone and PM10 for each scenario using dose-response functions from the peer-reviewed literature. They value cases of morbidity and premature mortality avoided using three approaches: Cost of illness and forgone earnings only (low estimate). Cost of illness, forgone earnings, and willingness to pay for avoided morbidity (central case estimate). Cost of illness, forgone earnings, willingness to pay for avoided morbidity, and willingness to pay for avoided mortality (high estimate). The results suggest that the benefits of a 10 percent reduction in ozone and PM10 in 2010 are about $760 million (in 1999 U.S. dollars) annually in the central case. The benefits of a 20 percent reduction in ozone and PM10 are about$1.49 billion annually. In each case the benefits of reducing ozone amount to about 15 percent of the total benefits. By estimating the magnitude of the benefits from air pollution control, the authors provide motivation for examining specific policies that could achieve the air pollution reductions that they value. They also provide unit values for the benefits from reductions in ambient air pollution (for example, per microgram of PM10) that could be used as inputs into a full cost-benefit analysisof air pollution control strategies.Montreal Protocol,Public Health Promotion,Global Environment Facility,Air Quality&Clean Air,Health Monitoring&Evaluation,Montreal Protocol,Air Quality&Clean Air,Health Monitoring&Evaluation,Global Environment Facility,Transport and Environment
