As one of the top countries with the highest casualties per capita in road traffic accidents, Thailand needs to raise public awareness about the economic loss from road traffic crashes. This paper calculates the value of productivity loss due to road traffic accidents in Thailand in 2017. Extensive data collection and analyses enable to compute income losses over time in case of fatalities, permanent disabilities as well as major and minor injuries. The results reveal that, at the end of 2017, the total amount of productivity loss caused by road traffic accidents alone was approximately 121 billion Baht (45 billions for fatalities, 7 for disabilities, 67.5 for serious injuries and 1.5 for slight injuries), or close to 0.8% of the country's GDP, which is very significant. At-risk age groups are determined in each case and we see that the 16–25 age group is bearing the highest burden in all types of accidents. Future policies can then be targeted to types of casualties and to a specific public.

The complexity of ecological-economic systems significantly reduces our ability to investigate their behavior and propose policies aimed at various environmental and/or economic objectives. Following recent suggestions for integrating nonlinear dynamic modeling with input-output (IO) modeling, we develop a fully dynamic ecological-economic model by integrating IO with system dynamics (SD) for better capturing critical attributes of ecological-economic systems. We also develop and evaluate various scenarios using policy impact and policy sensitivity analyses. The model and analysis are applied to the degradation of fish nursery habitats by industrial harbors in the Seine estuary (Haute-Normandie region, France). The modeling technique, dynamization, and scenarios allow us to show trade-offs between economic and ecological outcomes and evaluate the impacts of restoration scenarios and water quality improvement on the fish population.

While environmentally extended input-output (IO) models are commonly used for capturing interactions between ecosystems and economic systems, this kind of modelling cannot reflect interactions within the ecosystem. Isard's (1968) model has been the only exception. He entered interactions occurring within the ecosystem into IO. Nevertheless, given the linearity of IO, he could only analyze environmental issues in a linear fashion. We propose an alternative that reverses Isard's model types: the economic system is modelled within the ecosystem (not the contrary), as one of the ecosystem's components. To demonstrate its feasibility, we develop an ecological-economic model by integrating conventional economic IO within system dynamics (SD). After describing the methodological issues, we “test” the IO/SD model on ecological and economic data by applying it to the destruction and restoration of the Seine Estuary, France, where Common soles live. Our model brings insight into the consideration of feedback loops in the modelling of interactions between the ecosystem and the economic system. We believe such a tool may be of help to decision makers in mixing economic and environmental issues like, in our application case, fish habitat and harbour development.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

The Environmental Kuznets Curve (EKC) hypothesises that emissions first increase at low stages of development then decrease once a certain threshold has been reached. The EKC concept is usually used with per capita Gross Domestic Product as the explanatory variable. As others, we find mixed evidence, at best, of such a pattern for CO2 emissions with respect to per capita GDP. We also show that the share of manufacture in GDP and governance/institutions play a significant role in the CO2 emissions–income relationship. As GDP presents shortcomings in representing income, development in a broad perspective or human well-being, it is then replaced by the World Bank's Adjusted Net Savings (ANS, also known as Genuine Savings). Using the ANS as an explanatory variable, we show that the EKC is generally empirically supported for CO2 emissions. We also show that human capital and natural capital are the main drivers of the downward sloping part of the EKC.

Establishing nature reserves protects species from land cover conversion and the resulting loss of habitat. Even within a reserve, however, many factors such as fires and defoliating insects still threaten habitat and the survival of species. To address the risk to species survival after reserve establishment, reserve networks can be created that allow some redundancy of species coverage to maximize the expected number of species that survive in the presence of threats. In some regions, however, the threats to species within a reserve may be spatially correlated. As examples, fires, diseases, and pest infestations can spread from a starting point and threaten neighboring parcels’ habitats, in addition to damage caused at the initial location. This paper develops a reserve site selection optimization framework that compares the optimal reserve networks in cases where risks do and do not reflect spatial correlation. By exploring the impact of spatially-correlated risk on reserve networks on a stylized landscape and on an Oregon landscape, this analysis demonstrates an appropriate and feasible method for incorporating such post-reserve establishment risks in the reserve site selection literature as an additional tool to be further developed for future conservation planning.

Monetary valuation techniques are often used for evaluating the effect of a change in ecosystem services on components of human wellbeing, even though they face several drawbacks. This paper seeks to reconcile monetary valuation techniques with methods that address ecosystem-economy interactions by developing a guiding framework that limits the use of monetary valuation to various market simulations. Simulations of scenarios of environmental measures are carried out with a semi-dynamic hybrid input-output model. The guiding framework ensures that monetary valuation techniques contribute to the understanding of the impact of economic activities on changes in ecosystems services and the feedback impact of these changes on economic activities. The framework operates according to three criteria: (i) the category of ecosystem components (intermediate products, ecosystem services, benefits obtained from the ecosystem), (ii) existence of a market, intention to exchange or possibility for restoration or preservation, and (iii) direct/indirect monetary valuation techniques. The methodology is then tested with a case-study. © 2014 Elsevier B.V.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

The Walloon forest, which is geographically close to densely populated areas of Atlantic Europe, fulfils an important recreational function. Two surveys were set up, among which a large-scale statistical survey in 40 woodlands, distributed throughout the Walloon forest and resulting in over 4,000 questionnaires collected. These give information about the recreational activities carried out in the forest, which helps determine the unit value of visits. The regional value is based on the estimated number of visits annually for the total woodlands. Contingent valuation is used to estimate recreational values for this data set comprising the whole regional level with heterogeneous visits and comparisons with other methods and other hypotheses are undertaken. Although the valuation varies depending on the method and the application modalities selected, it is very large and confirms the importance of this non-benefit service and the weight it could carry in terms of regional forest policy.

Cet article aborde brièvement la relation entre croissance et environnement dans l’histoire de la théorie économique (des physiocrates aux néo-classiques) et situe cette relation comme un thème dans le développement de la littérature en économie environnementale. Il expose ensuite de manière comparative deux paradigmes de l’économie environnementale (économie de l’environnement au sens large versus économie écologique) et donc les approches faible et forte de la soutenabilité. Il confronte ensuite ces deux paradigmes à propos de la croissance et de la courbe environnementale de Kuznets et réalise une analyse empirique de cette courbe et des découplages éventuels qu’elle pourrait induire pour le dioxyde de carbone en Belgique et dans d’autres pays, pour en tirer des conclusions contemporaines quant à la relation entre croissance et environnement.JEL : Q00, Q01, Q54, Q56, Q57

The expansion of nature reserves is an important public policy strategy for the protection of biological diversity. In this paper, the authors use integer programming model structures derived from Location Set Covering Problem and Maximal Covering Location Problem approaches of location science as tools for selectively augmenting nature reserve sites for special status species protection. The linear programming models presented incorporate the following: biological constraints in the form of species' area needs; economic constraints in the form of opportunity costs of converting smaller administrative districts into nature reserves; and spatial constraints in the form of required connectivity among districts in site selection. The construction of a taxonomic data set for Thailand enables the implementation of the models, the comparison of results and evaluation of the differences in outcomes. The models build upon the existing nature reserve network in Thailand and suggest various public policy options that would augment the reserves for enhancing species protection and for possibly improving national conservation efforts at lowest costs.

As currently designed and implemented, the Clean Development Mechanism (CDM) under the Kyoto Protocol is a market mechanism that creates ‘offset’ credits, named CERs (certified emission reductions). These credits are issued to Annex I Parties that invest in projects both reducing emissions and contributing to sustainable development in developing countries. This paper explores how CER weights could be used to reform and improve this mechanism. On the one hand, weights strictly lower than 1, or discount factors, would improve the environmental effectiveness of the CDM, enhancing global greenhouse gas emission mitigation while addressing the additionality concern. On the other hand, weights higher than 1, or multiplication factors, could increase the competitiveness of project types and/or host countries currently underrepresented in the CDM pipeline. This paper concentrates on stimulating investment from developed nations to less developed countries and aims at reducing the disparity between the three main CDM host countries (Brazil, India and China) and less developed nations. Based on statistical data published by the United Nations Framework Convention on Climate Change, our analysis then considers different policies, estimates their impacts, and shows how a sensible mix of discounting and multiplication could lead to a more equitable geographical distribution of CDM projects and possibly create atmospheric benefits.

This article formulates and tests set covering and related models with spatial characteristics for selecting sites that provide habitat for species that are identified as “critical” (e.g., typically threatened, endangered, or rare), thereby enhancing their persistence. The first two models presented require the creation of a core area for each critical species and a buffer zone surrounding the core, with and without being constrained to include at least one representation of each and every common (i.e., noncritical) species. The final model aims at minimizing costs of protecting predetermined numbers of common species while all critical species remain covered and buffered. These models are implemented for occurrence data of terrestrial mammals in Oregon. They enable, among other things, a comparison between the budgetary impacts of reserve networks with and without buffering rings for critical species, and a determination of the marginal cost of common species protection.

The objective of this paper is to assess the economic impacts of reducing greenhouse gas emissions by decreasing industrial output in Canada to a level that will meet the target set out in the Kyoto Protocol. The study uses an ecological–economic Input–Output model combining economic components valued in monetary terms with ecologic components – GHG emissions – expressed in physical terms. Economic and greenhouse gas emissions data for Canada are computed in the same sectoral disaggregation. Three policy scenarios are considered: the first one uses the direct emission coefficients to allocate the reduction in industrial output, while the other two use the direct plus indirect emission coefficients. In the first two scenarios, the reduction in industrial sector output is allocated uniformly across sectors while it is allocated to the 12 largest emitting industries in the last one. The estimated impacts indicate that the results vary with the different allocation methods. The third policy scenario, allocation to the 12 largest emitting sectors, is the most cost effective of the three as the impacts of the Kyoto Protocol reduces Gross Domestic Product by 3.1% compared to 24% and 8.1% in the first two scenarios. Computed economic costs should be considered as upper-bounds because the model assumes immediate adjustment to the Kyoto Protocol and because flexibility mechanisms are not incorporated. The resulting upper-bound impact of the third scenario may seem to contradict those who claim that the Kyoto Protocol would place an unbearable burden on the Canadian economy.

The preservation of species diversity generally suggests protection of either the greatest number of species possible or all species. Requiring representation of each species in at least one parcel in the system and seeking the minimum number of parcels in the reserve system to achieve this requirement is termed the Species Set Covering Problem (SSCP). Nonetheless, it is important, as well, to consider the rarest of species, as their populations are the most in need of protection to assure their survival. This paper uses 0–1 programming models and an existing data set to study species protection, rarity, species abundance and species diversity. We employ for this purpose an integer programming model that uses the SSCP format to require at least one representation of each and every species, but that seeks in addition protection of the rarest species. This is achieved by maximizing redundant coverage of those species designated as rare. Results are then compared to those of the SSCP. Recognizing that resources available for conservation purchases could well be insufficient to represent all species at least once, we structure a model comparing coverage of the greatest number of species and redundant coverage of rare species. We develop a trade-off curve for this multi-objective problem in order to evaluate the opportunity cost of covering more species as redundant coverage of rare species decreases—and vice versa. Finally, various possible rarity sets and various budget proxies are considered along with their impacts on conservation policies, Pareto optimality and species diversity.

Cooperation in the economic sense considers efficiency issues. Cooperation in the political sense, like the Kyoto Protocol, considers other issues like equity and historical responsibility. The environmental and economic impacts of the Kyoto Protocol and other scenarios are thus examined. The US pullout may then be viewed, among others, as the result of not untying “economic” and “political” cooperation; and since the Protocol will be much less effective without the US, it is shown that an external economic stimulus should and may theoretically be found for retaining their participation.

Abatement cost and benefit projections through 2100are computed, assembled and interpreted with respectto various levels of emission reduction. Mathematicalexpressions describing regional costs and benefits asa function of abatement strategy are developed. Usingthese data and expressions, optimal abatementstrategies are defined for noncooperative andcooperative (Pareto optimal) policies. Thecooperative solution calls for an average emissionsreduction of 16.6 percent over the 1990–2100 period,as compared to 5.8 percent in the noncooperative case. Achieving the cooperative solution would require sidepayments to China and potentially to the U.S., as wellas stringent (though beneficial) restrictions onnon-OECD countries. It is argued that Paretooptimality is technically achievable but possiblyinfeasible in the real world.
