Aptidão agrícola das terras e sensibilidade ambiental: proposta metodológica.

O uso indiscriminado das terras, sem levar em conta suas potencialidades e graus de sensibilidade ambiental (fragilidade e/ou estabilidade) dos agroecossistemas, é uma das principais causas da degradação do solo, erosão e perda de sua capacidade produtiva. O objetivo central deste trabalho foi propor uma classificação de sensibilidade ambiental e avaliar a aptidão agrícola das terras da quadrícula de Ribeirão Preto-SP, visando identificar a fragilidade, estabilidade e potencialidade quanto ao uso das terras, como subsídios ao planejamento e gestão ambiental. A área localiza-se entre as coordenadas: 21°00' a 21°30' S e 47°30' a 48°00' WGr. Para a classificação da sensibilidade ambiental utilizou-se a equação universal de perda de solo (EUPS), tolerância de perdas do solo e índice de fragilidade; para avaliação do potencial agrícola, foi adotado o sistema de avaliação da aptidão agrícola das terras, com modificações. A classificação da sensibilidade ambiental, no nível de manejo B, revelou que 75,34% da quadrícula possui áreas com estabilidade variando entre muito estável, estável e moderadamente estável, e 20,91% de áreas frágeis e muito frágeis; no nível de manejo C, 82,03% das áreas Apresentaram estabilidade variando entre muito estável, estável e moderadamente estável, e 14,22% de áreas frágeis e muito frágeis. Na avaliação do potencial agrícola, foi encontrado que 77,73% das terras são adequadas para o uso com lavouras; 15,55% têm uso mais indicado para pasto Plantado, silvicultura e pastagem natural; e 2,97% foram indicadas para preservação da fauna e flora. A classificação da sensibilidade ambiental e avaliação da aptidão agrícola são importantes ferramentas, podendo subsidiar trabalhos sobre planejamento agroambiental e gerenciamentos ambientais.

Macroinvertebrados aquáticos como bioindicadores no processo de licenciamento ambiental no Brasil

Resumo: Licenciamento ambiental no Brasil é um procedimento com vários níveis e etapas, concebido como ferramenta preventiva aos potenciais danos ambientais causados pela implantação de empreendimentos. Embora este procedimento seja obrigatório desde meados da década de 1980, ainda é limitado no que diz respeito ao uso de informações biológicas para a avaliação e o monitoramento de ambientes aquáticos. Neste processo, o órgão licenciador (federal, estadual ou municipal) define as variáveis a serem medidas, tendo como referência o tipo e a magnitude do empreendimento e as características específicas do local proposto para sua instalação. Respostas biológicas devem ser usadas para medir os impactos sobre ecossistemas aquáticos e os macroinvertebrados constituem um grupo que apresenta vantagens como bioindicadores, sendo os mais utilizados para este fim. Em 2011, o Grupo de Trabalho Intersetorial em Biomonitoramento foi criado para discutir o uso de macroinvertebrados em programas de monitoramento. Este trabalho apresenta as reflexões e propostas deste grupo e fornece subsídios para a inclusão destes organismos nos termos de referência a serem aplicados nos processos de licenciamento ambiental no Brasil. Abstract: In Brazil, the environmental licensing process has many stages, and it was designed as a tool to identify the potential and to prevent environmental damages caused by enterprises. Although this procedure is required since the mid-1980s, it is still limited regarding the use of bioassessment and biomonitoring of aquatic ecosystems. In this process, the agency responsible for the licensing (federal, state or local) is the responsible for defining the parameters to be measured. Those parameters are required based on the type and magnitude of the project, and the specific environment and location proposed for its installation. We recommend that biological responses should be used to assess and monitor stressors on aquatic ecosystems. Macroinvertebrates have been used worldwide as bioindicators because they have some advantages over other biological groups for this purpose. In 2011, the ?Intersectoral Working Group on Biomonitoring? was created to discuss the use of macroinvertebrates in biomonitoring programs. This paper presents proposals and recommendations aiming to stimulate and provide guidance for the use of this group in the context of the environmental licensing process in Brazil. Resumen: En Brasil, el proceso de licenciamiento ambiental tiene varios niveles y etapas. Fue diseñado como una herramienta de prevención de posibles daños ambientales causados por la ejecución de proyectos. Aunque este procedimiento exista desde la década de 1980, siegue con limitaciones en relación al uso de la información biológica para la evaluación y control de los ecosistemas acuáticos. En este proceso, la agencia de licenciamiento (federal, estadual o local) es la que define las variables a mensurar en función del tipo y la magnitud del proyecto y las características específicas del lugar propuesto para su instalación. Las respuestas biológicas deben ser utilizadas para evaluar los impactos a los ambientes acuáticos, y el grupo de los macroinvertebrados tienen ventajas sobre otros grupos biológicos y son los más utilizados para este fin. En 2011, el ?Grupo de Trabajo Intersectorial de Biomonitoreo? fue creado para discutir el uso de los macro-invertebrados en los programas de monitoreo ambiental. Este artículo presenta reflexiones y propuestas de este grupo y ofrece subsidios para la inclusión de estos organismos en los términos de referencia que serán aplicados en el proceso de licenciamiento ambiental en Brasil.

PAH biomarkers for human health risk assessment: a review of the state-of-the-art

Polycyclic aromatic hydrocarbons (PAH) are widely distributed in the environment, and some are carcinogenic to human beings. The study of biomarkers has helped clarify the nature and magnitude of the human health risks posed by such substances. This article provides a review of the state-of-the-art on PAH biomarkers for human health risk assessment and also discusses their applicability within the context of environmental management in Brazil. The article discusses the methodologies for determination of some biomarkers such as 1-hydroxypyrene and PAH-DNA adducts. Cytogenetic markers, frequency of chromosomal aberrations, and micronucleus induction were considered for the evaluation of cancer risk. The current stage of studies on validation of such biomarkers was also approached.

Contaminated sites and brownfield management State of art in Brazil and in Germany

Purpose - The aim of this paper is to briefly present aspects of public brownfield management policies from Brazilian and German points of view. Design methodology approach - The data collection method combined literature and documental research. The bibliography included Brazilian and German literature about brownfield management. The documental research includes Brazilian and German legislation and official documents published by CETESB, the Environmental Company of the State of São Paulo, Brazil. Furthermore, publications of German governmental research institutions have been integrated in the paper. Findings - In Brazil, despite the lack of a federal public policy, the State of São Paulo has approved specific rules to deal with contaminated sites. Topics that could be targets of scientific studies have been identified. Experiences in Germany show that it is essential to have political will and cooperation between the different political levels and technical disciplines. Partnerships between German and Brazilian universities would be welcome as there is a wide range of opportunities for academic post-graduation studies and research focusing on human resources capacitation in environmental management. Originality value - The paper makes an original contribution of exploring an area (brownfield management) that is at the forefront of discussion in academe and industry

Relationships between human resource dimensions and environmental management in companies: proposal of a model

This work deals with the main contributions of human resource dimensions for the environmental management in a company. While the specialized literature concerning the technical aspects of environmental management expands, there is a gap in the bibliography: integrated approaches between human resource dimensions and environmental management. An extensive bibliographical review was undertaken in order to systematize the human resource dimensions and their contributions concerning the effectiveness of the environmental management system. A model that analyses the relationships between these dimensions and the typical phases of an environmental management system is presented, within a perspective of application for academicians and managers.

Contributions of HRM throughout the stages of environmental management: methodological triangulation applied to companies in Brazil

The purpose of this research is to analyze the contribution of human resources management throughout the evolutionary stages of environmental management in Brazilian companies. A theoretical framework concerning environmental management and its evolution and the `greening` of the functional and competitive dimensions of human resource management were developed. A methodological triangulation was developed in two complimentary phases. In the first phase, data were collected from 94 Brazilian companies with ISO 14001 certification. The data collected were analyzed and processed using statistical techniques. The conclusions of the first phase supported the second phase of this empirical research. The second phase consisted of a study of multiple cases in four Brazilian companies. The results show evidence of the first known empirical study of contributions of human resource dimensions throughout the stages of environmental management in Brazilian manufacturing companies.

A procedure to evaluate environmental rehabilitation in limestone quarries

A procedure to evaluate mine rehabilitation practices during the operational phase was developed and validated. It is based on a comparison of actually observed or documented practices with internationally recommended best practices (BP). A set of 150 BP statements was derived from international guides in order to establish the benchmark. The statements are arranged in six rehabilitation programs under three categories: (1) planning (2) operational and (3) management, corresponding to the adoption of the plan-do-check-act management systems model to mine rehabilitation. The procedure consists of (i) performing technical inspections guided by a series of field forms containing BP statements; (ii) classifying evidences in five categories; and (iii) calculating conformity indexes and levels. For testing and calibration purposes, the procedure was applied to nine limestone quarries and conformity indexes were calculated for the rehabilitation programs in each quarry. Most quarries featured poor planning practices, operational practices reached high conformity levels in 50% of the cases and management practices scored moderate conformity. Despite all quarries being ISO 14001 certified, their management systems pay low attention to issues pertaining to land rehabilitation and biodiversity. The best results were achieved by a quarry whose expansion was recently submitted to the environmental impact assessment process, suggesting that public scrutiny may play a positive role in enhancing rehabilitation practices. Conformity indexes and levels can be used to chart the evolution of rehabilitation practices at regular intervals, to establish corporate goals and for communication with stakeholders.

Ocupação urbana em áreas de preservação permanente : o caso do manguezal da área continental de Vitória/ES

This research aims to diagnose the environmental impacts caused by the growth of urban occupations over the mangrove in the continental area of Vitória. It is justified by the gradual degradation of mangroves in Vitória that has inestimable importance to the landscape, to the environment and to the economy. With the growth of urban population in Brazil and around the world, researches like this, about environmental management, are essential to allow cities to grow more sustainably and well planned. The thesis was initially based on the study of occupations of Permanent Preservation Areas in general, with the presentation of the basic concepts and reflections, and later on territorial analysis of some protected areas and their surroundings, and the study of the empirical object, a polygon that covers urban areas and mangroves on the continental part of Vitória. The study hopes to promote a reflection and a discussion about the importance of maintenance of protected natural areas inside the cities, generating knowledge about the importance of mangrove and diagnose how it has been urbanized, protected or degraded over the years

Conception of a flexible integrator and lean model for integrated management systems

Management systems standards (MSSs) have developed in an unprecedented manner in the last few years. These MSS cover a wide array of different disciplines, aims and activities of organisations. Also, organisations are populated with an enormous diversity of independent management systems (MSs). An integrated management system (IMS) tends to integrate some or all components of the business. Maximising their integration in one coherent and efficient MS is increasingly a strategic priority and constitutes an opportunity for businesses to be more competitive and consequently, promote its sustainable success. Those organisations that are quicker and more efficient in their integration and continuous improvement will have a competitive advantage in obtaining sustainable value in our global and competitive business world. Several scholars have proposed various theoretical approaches regarding the integration of management sub-systems, leading to the conclusion that there is no common practice for all organisations as they encompass different characteristics. One other author shows that several tangible and intangible gains for organisations, as well as to their internal and external stakeholders, are achieved with the integration of the individual standardised MSs. The purpose of this work was to conceive a model, Flexible, Integrator and Lean for IMSs, according to ISO 9001 for quality; ISO 14001 for environment and OHSAS 18001 for occupational health and safety (IMS–QES), that can be adapted and progressively assimilate other MSs, such as, SA 8000/ISO 26000 for social accountability, ISO 31000 for risk management and ISO/IEC 27001 for information security management, among others. The IMS–QES model was designed in the real environment of an industrial Portuguese small and medium enterprise, that over the years has been adopting, gradually, in whole or in part, individual MSSs. The developed model is based on a preliminary investigation conducted through a questionnaire. The strategy and research methods have taken into consideration the case study. Among the main findings of the survey we highlight: the creation of added value for the business through the elimination of several organisational wastes; the integrated management of the sustainability components; the elimination of conflicts between independent MS; dialogue with the main stakeholders and commitment to their ongoing satisfaction and increased contribution to the company’s competitiveness; and greater valorisation and motivation of employees as a result of the expansion of their skill base, actions and responsibilities, with their consequent empowerment. A set of key performance indicators (KPIs) constitute the support, in a perspective of business excellence, to the follow up of the organisation’s progress towards the vision and achievement of the defined objectives in the context of each component of the IMS model. The conceived model had many phases and the one presented in this work is the last required for the integration of quality, environment, safety and others individual standardised MSs. Globally, the investigation results, by themselves, justified and prioritised the conception of an IMS–QES model, to be implemented at the company where the investigation was conducted, but also a generic model of an IMS, which may be more flexible, integrator and lean as possible, potentiating the efficiency, added value both in the present and, fundamentally, for future.

Certification and integration of management systems: the experience of Portuguese small and medium enterprises

The purpose of this study was to characterize the situation of Portuguese Small and Medium Enterprises (SMEs) concerning the certification of their Quality Management Systems (QMS), Environmental Management Systems (EMS) and Occupational Health and Safety Management Systems (OHSMS), in their individually form, to identify benefits, drawbacks and difficulties associated with the certification process and to characterize the level of integration that has been achieved. This research was based on a survey carried out by the research team; it was administered to 46 Portuguese SMEs. Our sample comprised 20 firms (43%) from the Trade/Services activity sector, 17 (37%) from the Industrial sector, 5 (11%) from the Electricity/Telecommunications sector and 4 (9%) from the Construction area. All SMEs surveyed were certified according to the ISO 9001 (100%), a quarter of firms were certified according to the ISO 14001 (26.1%) and a few certified by OHSAS 18001 (15.2%). We undertook a multivariate cluster analysis, which enabled grouping variables into homogeneous groups or one or more common characteristics of the SMEs participating in the study. Results show that the main benefits that Portuguese SMEs have gained from the referred certifications have been, among others, an improvement of both their internal organization and external image. We also present the main difficulties in achieving certification. Overall, 7 of the Portuguese SMEs examined indicated that the main benefits of the IMS implementation management included costs reduction, increased employee training and easier compliance of legislation. The respective drawbacks and difficulties are also presented. Finally, we presented the main integrated items in the certified Portuguese SMEs we examined.
