SUMMARYA mathematical model has been developed which allows estimation of the epidemiological and economic effects of different tetanus vaccination strategies. The model was used to simulate the epidemiology of tetanus in italy from 1955 to 1982, and then applied to a district of Tuscany by utilizing data obtained from a seroepidemiological survey carried out in the same area. For this district we simulated vaccination programmes designed to reach, within 1 or 10 years, coverages of 60 or 90% of the population aged over 10 years who had not been exposed to the neonatal vaccination programme. The most effective strategy, from both the epidemiological and economic point of view, seems to be 90% coverage reached in 1 year's time. Benefits would be increased by improving the reliability of vaccinal anamnesis.

Green roofs respond to a need of today’s society to orient its development towards sustainability. Architecture and urban planning, as builders of the modern city, play a crucial role in the search for a balance between social, environmental and economic growth. Green roofs imply recognized benefits in all three fields, but a study of the economic viability of these solutions is necessary, especially in the field of rehabilitation with tighter budgets. Through a cost-benefit analysis throughout its useful life, it is intended to avoid that the initial construction cost of a green roof, or any sustainable construction, could discourage users, helping them to understand its global dimension from an economic point of view.

During the last century there were two distinct and profound changes in attitudes to animals. First, it became widely understood that human activities and anthropogenic changes to the environment present a serious threat to biological diversity. In response to this many programmes to protect habitat and to conserve species have been launched. Second, advances in various fields of science led to a strengthening belief in many societies that a wide range of animals may have the capacity for consciousness and thus suffering. This has led to growing concern for the welfare of animals - the quality of their lives - and to the development of extensive bodies of welfare legislation in many countries. Concerns for species conservation and concerns for individual animal welfare do not always pull in the same direction. Around the world, conflicts are becoming commonplace between those who believe it can be justifiable to compromise the interests of individual animals in order to prevent species extinctions and those who do not. Such conflicts may be addressed and hopefully avoided or minimized through use of an ethical review process in which conservation benefits and welfare costs are carefully identified, considered and weighed in a cost/benefit analysis. A second function of this review process is to ensure that, where the decision is taken to proceed with a conservation programme that may adversely affect the welfare of some individuals, all necessary steps are taken to minimize these threats and their possible impacts.

Abstract The paper presents possibilities of an economic evaluation of hard coal mines, using Cost Benefit Analysis (CBA). Suggested methodology for CBA applied to the economic evaluation of a mine allows to conduct a complex evaluation of mine’s functionality in connection to Polish conditions. Additionally to financial aspects, significant from the point of view of the mine’s owner, the paper includes social and environmental effects as a result of mining activities. Proposed methodology has undergone tests which used averaged data obtained from two selected hard coal mines located in the Upper Silesian Coal Basin. Presented results confirm the validity of social costs and benefits, and environmental losses resulting from mining operation, which were included in analysis comprehensively evaluating the efficiency of hard coal mines.

The redesigning of tires is addressed from two points of view, namely the structure of the materials and the constructive shape of these products. The necessity for research is justified by the fact that even during the product design stage, there may be situations that can irreversibly affect the separation of product components (rubber and insertion), and because it is strictly necessary to achieve the reuse and recycling of waste components. The proposed redesign refers to the inscription of the types of materials that are present in each area on the lateral surface of the tire. Thus, the new redesign has positive effects both economically and socially. To highlight these, a cost-benefit analysis (CBA) has been applied and the net present value (NPV) as well as the internal rate of return (IRR) have been determined for the classic scenario and for the two proposed scenarios. Testing the financial sustainability of the proposed solution was done through sensitivity analysis. An analysis of the new tire design from the point of view of the circular economy was also presented. The results obtained have highlighted the effectiveness of the proposed solution from a technical, economic, social, and protection of the environment point of view.

O processo de decisões quanto às alterações ambientais causadas pela construção e operação do sistema de produção e transmissão de energia elétrica tem sido tradicionalmente instruído pela sua análise econômica do ponto de vista empresarial. Uma análise custo-benefício seria suficiente, dentro deste enfoque. Entretanto, a natureza dessas alterações transcende o cálculo econômico feito sob os parâmetros da teoria econômica neoclássica. Nada mais distante de uma coletividade de indivíduos que maximizam suas utilidades, do que os indivíduos que têm poder de influir sobre as decisões mais importantes do setor. O exame histórico da evolução do setor elétrico no Brasil mostra um cenário em que diferentes grupos de atores sociais ou stakeholders, vêm aplicando diferentes paradigmas de análise nas decisões quanto ao uso dos recursos hídricos, alterações nos cursos d’água e na atmosfera. O estudo da dinâmica de evolução dos vários atores sociais, e das relações e embates entre eles são fundamentais para a compreensão do processo histórico. Permite também uma adequada separação e atribuição dos interesses e objetivos aos diversos grupos, pressuposto para qualquer tentativa de síntese em nome de um interesse mais amplo. Abstract The decision making process for the environmental alterations caused by the construction and operation of power plants and transmission system has been instructed traditionally by economical analysis of the business point of view. A cost-benefit analysis would be sufficient, inside of this focus. However, the nature of those alterations transcends economic calculations done under the parameters of the neoclassical economical theory. The individuals that have power of influence over the most important decisions of the power industry couldn’t be more distant of a collectivity of individuals that maximize their utilities. The historical examination of the evolution of the power industry in Brazil shows a scenario in that different groups of stakeholders apply different analysis paradigms in the decisions as for the use of hydro resources, alterations in the water bodies and in the atmosphere. The study of the dynamics of the several social actors’ evolution, and of the relationships and collisions among them are fundamental for the understanding of the historical process. It also allows an appropriate separation and attribution of the interests and objectives to the several groups, presupposition for any synthesis attempt on behalf of a wider interest.

The present paper carries out a cost benefit analysis of centralized wastewater reuse systems in Beijing. This study consists of two parts: financial analysis and economic analysis. The financial analysis is made from the point of view of plant manager, in which financial benefits and cost is calculated. The economic analysis is made from the point of view of society, in which the economic, environmental and social benefits and cost are determined. The results of financial analysis show that the financial benefits are larger than cost, which means the centralized wastewater reuse systems are financially feasible. It implies that the investment on centralized wastewater reuse systems is profitable. The results of economic analysis show that the ratio of benefit to cost is larger than 1, which means the centralized wastewater reuse systems are economically feasible. It implies that centralized wastewater reuse systems have positive effects on the society. From the point of view of plant manager, centralized wastewater reuse systems could operate in a long term, while from the point of view of government or society, the centralized wastewater reuse systems are worth to be promoted.

Although the increasing adoption of electric vehicles (EVs) is overall positive for the environment and for the sustainable use of resources, the extra effort that requires purchasing an EV when compared to an equivalent internal combustion engine (ICE) competitor make them less appealing from an economical point of view. In addition to that, there are other challenges in EVs (autonomy, battery, recharge time, etc.) that are non-existent in ICE vehicles. Nevertheless, the possibility of providing electricity to the power grid via vehicle-to-grid technology (V2G), along with lower maintenance costs, could prove that EVs are the most economically efficient option in the long run. Indeed, enabling V2G would make EVs capable of saving some costs for their vehicle owners, thus making them a better long-term mobility choice that could trigger deep changes in habits of vehicle owners. This paper describes a cost–benefit analysis of how consumers can make use of V2G solutions, in a way that they can use their vehicle for transport purposes and obtain revenues when injecting energy into the power grid.

(1) Background: in epidemiological terms, it has been possible to calculate the savings in health resources and the reduction in health effects of COVID vaccines. From the point of view of economic evaluation, some studies have estimated its cost-effectiveness with the vaccination showing highly favorable results, which in some cases is cost-saving; (2) Methods: a cost-benefit analysis of the vaccination campaign in the North Metropolitan Health Region (Catalonia). An epidemiological model based on observational data and before and after comparison is used. The information on the doses used and the resources assigned (conventional hospital beds, ICU, number of tests) has been extracted from administrative data from the largest Primary Care provider in the region (Catalan Institute of Health). A distinction is made between the social perspective and the health system; (3) Results: the costs of vaccination are estimated at 137 million euros (€48.05/dose administered). This figure is significantly lower than the positive impacts of the vaccination campaign, which are estimated at 470 million euros (€164/dose administered). Of these, 18% corresponds to the reduction of ICU discharges, 16% to the reduction in conventional hospital discharges, 5% to the reduction in PCR tests and 1% to the reduction of RAT tests. Monetization of deaths and cases with sequelae avoided account for 53% and 5% of total savings, respectively. The benefit/cost ratio is estimated at 3.4 from a social perspective and 1.2 from a health system perspective. The social benefits of vaccination are estimated at €116.67 per dose of vaccine given (€19.93 from the point of view of the health system); (4) Conclusions: the mass vaccination campaign against COVID is cost-saving. From a social perspective, most of these savings come from the monetization of the reduction in mortality and cases with sequelae, although the intervention is equally widely cost-effective from the point of view of the health system thanks to the reduction in the use of resources. It is concluded that, from an economic perspective, the vaccination campaign has high social returns.

Agriculture in Upper Egypt is characterized by unsustainable farming practices and a lack of the use of market intelligence. Improving agriculture in Upper Egypt is necessary, as farmers in this region need to meet the quality standards required by international markets if they are to increase export volumes. For this reason, agricultural interventions are required to transition from the current traditional farming systems and marketing practices to sustainable conservation farming practices and the use of market intelligence and logistics. The main aim of this research study is to assess the potential for improving the livelihoods of rural communities by conducting a cost–benefit analysis (CBA) and conducting a risk analysis using the Monte Carlo simulation method for the proposed agricultural interventions. Our results imply that the analyzed interventions are viable from both a financial and socio-economic point of view. The impacts of the interventions reveal real incremental employment opportunities at the farming level. In addition, the interventions have a very low probability of negative returns and become almost zero when we add the economic benefit to society.
