Estudi del protocol de mostreig i de l’afectació de la pressió humana en 4 microconques del riu Estelí (Nicaragua)

Objectius generals: Diagnosi de l’estat actual del riu Esteli. Avaluar la metodologia i proposar en el protocol del monitoreig.Estudiar si les comunitats de macroinvertebrats aquatics es veu afectades pel grau de pressió humana.Objectius específics: Comparar les mostres preses en dos mesos consecutius, per conèixer si les comunitats varien prou com per, agafar mostres cada mes en comptes de cada dos mesos. Determinar la qualitat de l’estació en diversos punts del riu Esteli considerant tant els resultats obtinguts a partir de les variables físicoquimiques de l’aigua, com les variables biològiques. Avaluar si la pressió humana afecta de manera diferent els diversos grups taxonòmics de macroinvertebrats de l’aigua. Avaluar amb quin índex biòtic es posa mes de manifest la pressió antròpica. Estudiar quines son les relacions de les diverses famílies de macroinvertebrats amb els paràmetres físicoquimics de l’aigua, i determinar si aquestes relacions varien en funcio del mes de mostreig o de l’ús del sòl.

Niagara River (Ontario) Remedial Action Plan fonds, 1984-1997, n.d.

The Niagara River Remedial Action Plan was part of an initiative to restore the integrity of the Great Lakes Basin ecosystem. In 1972, the Great Lakes Water Quality Agreement was signed by both Canada and the United States to demonstrate their commitment to protecting this valuable resource. An amendment in 1987 stipulated that Remedial Action Plans (RAPs) be implemented in 43 ecologically compromised areas known as Areas of Concern. The Niagara River was designated as one of these areas by federal and provincial governments and the International Joint Commission, an independent and binational organization that deals with issues concerning the use and quality of boundary waters between Canada and the United States. Although the affected area included parts of both the Canadian and American side of the river, Remedial Action Plans were developed separately in both Canada and the United States. The Niagara River (Ontario) RAP is a three-stage process requiring collaboration between numerous government agencies and the public. Environment Canada, the Ontario Ministry of the Environment, and the Niagara Peninsula Conservation Authority are the agencies guiding the development and implementation of the Niagara River (Ontario) RAP. The first stage is to determine the severity and causes of the environmental degradation that resulted in the location being designated an Area of Concern; the second stage is to identify and implement actions that will restore and protect the health of the ecosystem; and the third stage is to monitor the area to ensure that the ecosystem’s health has been restored. Stage one of the RAP commenced in January 1989 when a Public Advisory Committee (PAC) was established. This committee was comprised of concerned citizens and representatives from various community groups, associations, industries and municipalities. After several years of consultation, the Niagara River (Ontario) Remedial Action Plan Stage 2 Report was released in 1995. It contained 16 goals and 37 recommendations. Among them was the need for Canadians and Americans to work more collaboratively in order to successfully restore the water quality in the Niagara River. Stage three of the Niagara River (Ontario) RAP is currently ongoing, but it is estimated that it will be completed by 2015. At that point, the Niagara River Area of Concern will be delisted, although monitoring of the area will continue to ensure it remains healthy.

In the eye of the storm: exploring the introduction of environmental issues in the production function in Brazilian companies

This article aims to analyse the introduction of environmental issues in the context of the production function, which has been referred to as the organisational area to lead corporate environmental management. With that purpose, the theoretical references for corporate environmental management and the necessary alterations in production function have been organised to include environmental aspects, especially in terms of product and process development, quality management, and logistics. Considering that this research field still lacks empirical evidence for Brazilian companies, four case studies were conducted using companies located in the country. The environmental management maturity level of those companies tends to follow the rate with which the environmental issue is introduced in production sub-areas, especially in the product development process. However, in most cases we found that the companies had difficulties in structuring the insertion of the environmental dimension in logistics. The final notes point out the distance observed between what is recommended by international literature and the reality of Brazilian companies in the challenge of making the production function environmentally friendly.

Environmental management systems implementation

All organisations make some contribution to the degradation of the environment through their use of resources and production of waste. Environmental management systems (EMS) standards can provide a tool for companies to systematically reduce their environmental impacts. ISO 14001 was published in 1996. This fitted in with plans of the case study company to take proactive action in this area, even though there was no legislative requirement for them to do so. As EMS implementation was a new area at the time, appropriate methodologies were developed to address different aspects of the implementation, and ISO 14001 was successfully implemented in the company. The results of the primary research included: ♦ Drawing up a methodology for identifying and interpreting the environmental legislation that may have an impact on the organisation and compiling a register of such regulations. ♦ Developing a robust methodology for assessing significant environmental aspects and impacts and applying this to the software company. ♦ Establishing objectives and targets for those aspects identified as significant and implementing environmental management programmes to meet these. ♦ Developing an internal environmental audit procedure based on auditing against the significant aspects. ♦ Integrating areas of the EMS with the existing quality management system in order to avoid duplication of effort. ♦ Undergoing an external assessment process in order to achieve certification of the system. The thesis concludes that the systematic approach defined in ISO 14001 provided a mechanism that the organisation was able to adopt to bring about improvement in its environmental performance. The system was based on a thorough evaluation of the organisation's significant environmental aspects in order to bring about a reduction in its negative impacts. The ISO 14001 requirement for continual improvement is the key driver of the system, and this is what differentiates it from ISO 9000.
