VALORAÇÃO DE ATIVOS E MULTAS AMBIENTAIS: ANÁLISE SIMULADA DE EMPREENDIMENTOS HOTELEIROS EM ÁREAS PROTEGIDAS

O crescimento desordenado e a ausência de políticas públicas mais eficientes levaram a uma diversificação quanto ao uso dos recursos naturais, principalmente no que se refere à água para o saneamento básico. O marco regulatório estabelecido na década de 1980 registrou as políticas públicas para o meio ambiente, que trouxeram avanços sobre o tema, desencadeando uma série de ações voltadas tanto para a estrutura burocrática e da prevenção, quanto solução para os problemas de degradação e esgotamento dos recursos naturais. Com o advento das leis específicas de proteção aos mananciais e mediante a lei 13.579/09 do Estado de São Paulo que trata sobre a área da Billings, percebeu-se um avanço na questão do gerenciamento para proteção e desenvolvimento de acordo com as características da região. Instrumentos de políticas públicas para conter as ações referentes aos danos causados ao meio ambiente, como a lei contra crimes ambientais foram às ações práticas do Estado para conter tais ações. O Objetivo desta pesquisa é analisar as possíveis discrepâncias entre as penalidades financeiras aplicadas na ocorrência das infrações ambientais e os modelos de valoração dos ativos ambientais, utilizando a simulação de implantação de um hotel em áreas de proteção e recuperação de manancial no Município de São Bernardo do Campo no Estado de São Paulo. O desenvolvimento da pesquisa se baseou no método de custo de reposição (MCR) para dimensionar os possíveis impactos gerados por um empreendimento hoteleiro e seu respectivo valor econômico. Posteriormente, os impactos ambientais foram relacionados com a legislação do município para determinar os valores das possíveis penalidades aplicáveis ao dano causado. Dentre os resultados levantados, verificou-se uma significativa discrepância entre a valoração econômica e as multas aplicáveis, sendo que nos impactos referentes a impermeabilidade do solo e contaminação do lençol freático, com diferenças superiores em relação às penalidades de R$ 804.922,78 e R$ 453.333,33 respectivamente. A partir da metodologia aplicada na pesquisa, observou-se que as penalidades incidentes em casos de danos ao meio ambiente, muitas vezes não atinge o objetivo, que é inibir a ação do infrator, pois o real custo econômico não é medido na aplicação do valor da multa.

Performance of small and medium enterprises and the impact of environmental variables: evidence from Vietnam

thesis is developed from a real life application of performance evaluation of small and medium-sized enterprises (SMEs) in Vietnam. The thesis presents two main methodological developments on evaluation of dichotomous environment variable impacts on technical efficiency. Taking into account the selection bias the thesis proposes a revised frontier separation approach for the seminal Data Envelopment Analysis (DEA) model which was developed by Charnes, Cooper, and Rhodes (1981). The revised frontier separation approach is based on a nearest neighbour propensity score matching pairing treated SMEs with their counterfactuals on the propensity score. The thesis develops order-m frontier conditioning on propensity score from the conditional order-m approach proposed by Cazals, Florens, and Simar (2002), advocated by Daraio and Simar (2005). By this development, the thesis allows the application of the conditional order-m approach with a dichotomous environment variable taking into account the existence of the self-selection problem of impact evaluation. Monte Carlo style simulations have been built to examine the effectiveness of the aforementioned developments. Methodological developments of the thesis are applied in empirical studies to evaluate the impact of training programmes on the performance of food processing SMEs and the impact of exporting on technical efficiency of textile and garment SMEs of Vietnam. The analysis shows that training programmes have no significant impact on the technical efficiency of food processing SMEs. Moreover, the analysis confirms the conclusion of the export literature that exporters are self selected into the sector. The thesis finds no significant impact from exporting activities on technical efficiency of textile and garment SMEs. However, large bias has been eliminated by the proposed approach. Results of empirical studies contribute to the understanding of the impact of different environmental variables on the performance of SMEs. It helps policy makers to design proper policy supporting the development of Vietnamese SMEs.

Practice report: the role of environmental factors in industrial site selection activities: a case of limestone quarry expansion in Barbados, West Indies

Site selection is a key activity for quarry expansion to support cement production, and is governed by factors such as resource availability, logistics, costs, and socio-environmental factors. Adequate consideration of all factors facilitates both industrial productivity and sustainable economic growth. This study illustrates the site selection process that was undertaken for the expansion of limestone quarry operations to support cement production in Barbados. First, alternate sites with adequate resources to support a 25-year development horizon were identified. Second, socio-environmental conditions were described and potential impacts identified. Third, a comparative matrix was constructed to evaluate relative site characteristics with respect to physical, ecological, socio-cultural and economic factors. The study shows that environmental factors were essential to the final site recommendation.

Creation of relational assets through the 'library of equipment' model:an industrial modernization approach of Japan's local technology centres

SMEs with a weak internal R&D capacity show the tendency to shy away from using external sources of technical expertise. The tendency deters providers of industrial modernization services from supporting such structurally weak SMEs. This paper examines how Japan's local technology centres - kosetsushi - remove the bottleneck and reach out to a significant proportion of SMEs with a weak R&D capacity in their localities. Kosetsushi centres sustain habitual interactions with client firms through 'low information gap' services solving immediate needs and lead the clients to a riskier and longer path toward innovation capacity building. This gives kosetsushi centres a position distinct from universities and consultancies in the regional innovation system. While long-term relationships between kosetsushi centres and their client firms can increase switching costs and produce lock-in effects, a case study of two kosetsushi centres illustrates the importance of 'low-information gap' services and relational assets created thereby to the modernization of SMEs with a weak internal R&D capacity. The paper calls for long-term commitment by the public sector if it addresses the issue through modernization services.

The valuation of travel time savings in least developed countries:theoretical and empirical challenges and results from a field study

In developed countries travel time savings can account for as much as 80% of the overall benefits arising from transport infrastructure and service improvements. In developing countries they are generally ignored in transport project appraisals, notwithstanding their importance. One of the reasons for ignoring these benefits in the developing countries is that there is insufficient empirical evidence to support the conventional models for valuing travel time where work patterns, particularly of the poor, are diverse and it is difficult to distinguish between work and non-work activities. The exclusion of time saving benefits may lead to a bias against investment decisions that benefit the poor and understate the poverty reduction potential of transport investments in Least Developed Countries (LDCs). This is because the poor undertake most travel and transport by walking and headloading on local roads, tracks and paths and improvements of local infrastructure and services bring large time saving benefits for them through modal shifts. The paper reports on an empirical study to develop a methodology for valuing rural travel time savings in the LDCs. Apart from identifying the theoretical and empirical issues in valuing travel time savings in the LDCs, the paper presents and discusses the results of an analysis of data from Bangladesh. Some of the study findings challenge the conventional wisdom concerning the time saving values. The Bangladesh study suggests that the western concept of dividing travel time savings into working and non-working time savings is broadly valid in the developing country context. The study validates the use of preference methods in valuing non-working time saving values. However, stated preference (SP) method is more appropriate than revealed preference (RP) method.

Influence of environmental factors on zoospores of Saprolegnia diclina

The numbers of zoospores produced by a pathogenic strain of Saprolegnia diclina and their behaviour are markedly influenced by a variety of environmental variables including temperature, pH, oxygen tension and the presence of biocides. The use of the latter is not recommended, as fish readily succumb to equivalent concentrations of biocides. Analysis of the pattern of distribution of resulting zoospore cysts demonstrates that zoospores become dispersed by random movement even while in the proximity of the parent colony’s nutrient source. However, the presence of amino acids, in particular aspartic and glutamic acid, at concentrations which occur in fish tissue promotes the directed movement of zoospores towards the nutrient source thereby encouraging the colonization of fresh sites.

Greening operations: an investigation of environmental decision making

This PhD thesis belongs to three main knowledge domains: operations management, environmental management, and decision making. Having the automotive industry as the key sector, the investigation was undertaken aiming at deepening the understanding of environmental decision making processes in the operations function. The central research question for this thesis is ?Why and how do manufacturing companies take environmental decisions? This PhD research project used a case study research strategy supplemented by secondary data analysis and the testing and evaluation of a proposed systems thinking model for environmental decision making. Interviews and focus groups were the main methods for data collection. The findings of the thesis show that companies that want to be in the environmental leadership will need to take environmental decisions beyond manufacturing processes. Because the benefits (including financial gain) of non-manufacturing activities are not clear yet the decisions related to product design, supply chain and facilities are fully embedded with complexity, subjectivism, and intrinsic risk. Nevertheless, this is the challenge environmental leaders will face - they may enter in a paradoxical state of their decisions – where although the risk of going greener is high, the risk of not doing it is even higher.

Lessons learned from INTAMAP, an interoperable web service for the real-time interpolation of environmental variables

Interpolated data are an important part of the environmental information exchange as many variables can only be measured at situate discrete sampling locations. Spatial interpolation is a complex operation that has traditionally required expert treatment, making automation a serious challenge. This paper presents a few lessons learnt from INTAMAP, a project that is developing an interoperable web processing service (WPS) for the automatic interpolation of environmental data using advanced geostatistics, adopting a Service Oriented Architecture (SOA). The “rainbow box” approach we followed provides access to the functionality at a whole range of different levels. We show here how the integration of open standards, open source and powerful statistical processing capabilities allows us to automate a complex process while offering users a level of access and control that best suits their requirements. This facilitates benchmarking exercises as well as the regular reporting of environmental information without requiring remote users to have specialized skills in geostatistics.

Automated mapping of environmental variables from a SEIS or SISE perspective

The INTAMAP FP6 project has developed an interoperable framework for real-time automatic mapping of critical environmental variables by extending spatial statistical methods and employing open, web-based, data exchange protocols and visualisation tools. This paper will give an overview of the underlying problem, of the project, and discuss which problems it has solved and which open problems seem to be most relevant to deal with next. The interpolation problem that INTAMAP solves is the generic problem of spatial interpolation of environmental variables without user interaction, based on measurements of e.g. PM10, rainfall or gamma dose rate, at arbitrary locations or over a regular grid covering the area of interest. It deals with problems of varying spatial resolution of measurements, the interpolation of averages over larger areas, and with providing information on the interpolation error to the end-user. In addition, monitoring network optimisation is addressed in a non-automatic context.

Effects of environmental temperature on members of the mucorales

The following investigation characterises the interaction between temperature and growth in psychrophilic, mesophilic and thermophilic fungi in order to gain further insight into the physiological mechanisms underlying fungal growth at extreme temperatures. In the first part of the investigation, the effect of environmental temperature on the growth of vegetative mycelium and sporangiospore production and germination was considered in order to determine the cardinal temperatures of these activities in different thermal groups. Subsequent investigations of plasma membrane permeability suggested that plasma membrane structure and function may be significant in establishing both the upper and lower growth temperature limits characteristic of psychrophiles, mesophiles and thermophiles. Analysis of the plasma membrane fractions revealed significant differences in membrane phospholipid composition between these thermal groups and it is suggested that the differing cardinal growth temperatures characteristic of psychrophilic, mesophilic and thermophilic fungi reflect the temperature ranges over which these organisms exhibit levels of plasma membrane fluidity sufficient to maintain membrane-associated growth processes. In contrast, the membrane protein components appear uniform in both character and thermostability and are therefore unlikely to contribute to this phenomenon.

The design of environmental test rigs

Product reliability and its environmental performance have become critical elements within a product's specification and design. To obtain a high level of confidence in the reliability of the design it is customary to test the design under realistic conditions in a laboratory. The objective of the work is to examine the feasibility of designing mechanical test rigs which exhibit prescribed dynamical characteristics. The design is then attached to the rig and excitation is applied to the rig, which then transmits representative vibration levels into the product. The philosophical considerations made at the outset of the project are discussed as they form the basis for the resulting design methodologies. It is attempted to directly identify the parameters of a test rig from the spatial model derived during the system identification process. It is shown to be impossible to identify a feasible test rig design using this technique. A finite dimensional optimal design methodology is developed which identifies the parameters of a discrete spring/mass system which is dynamically similar to a point coordinate on a continuous structure. This design methodology is incorporated within another procedure which derives a structure comprising a continuous element and a discrete system. This methodology is used to obtain point coordinate similarity for two planes of motion, which is validated by experimental tests. A limitation of this approach is that it is impossible to achieve multi-coordinate similarity due to an interaction of the discrete system and the continuous element at points away from the coordinate of interest. During the work the importance of the continuous element is highlighted and a design methodology is developed for continuous structures. The design methodology is based upon distributed parameter optimal design techniques and allows an initial poor design estimate to be moved in a feasible direction towards an acceptable design solution. Cumulative damage theory is used to provide a quantitative method of assessing the quality of dynamic similarity. It is shown that the combination of modal analysis techniques and cumulative damage theory provides a feasible design synthesis methodology for representative test rigs.
