The main objective of this article is to discuss the Brazilian environmental legislation and policies towards the development of navigation and port management. The research illustrated some difficulties faced by the country and make suggestions to overcome it. The construction of the environmental legal framework began in the early 1960s and resulted in a very complex system, as a consequence of policies adopted by the country. Nowadays Brazilian environmental policies are developed in democratic and participative way, although with elevated degree of bureaucracy and lack of integration among the several governmental agencies, which makes the approval of environmental certifications demand several years for new port projects or improvements, which delays the economic development of the country. Efforts have been made to simplify the licensing process. As result of this research two flowchart for environmental licenses of ports installation are shown: The first shows the process until 2009 and the second shows the process nowadays. This become an important issue due the fact that inland navigation is one of the less pollutant modes of transportation, and although, the process of environmental certification was simplified, if compare with 2009, it is still complex and time-consuming, delaying the development of the infrastructure. © 2012 Elsevier Ltd.

Este Ponto de Vista resume as conclusões de um Workshop conjunto, organizado pelos três Programas da FAPESP na Área Ambiental - BIOTA (O Instituto Virtual da Biodiversidade) - BIOEN (Pesquisa em Bioenergia) - Mudanças Climáticas, para discutir a contribuição da comunidade científica para a RIO+20, a Conferência das Nações Unidas para o Desenvolvimento Sustentável. O grupo de pesquisadores brasileiros reunidos pela FAPESP no início de março de 2012 levantou as seguintes preocupações: a) o número reduzido de oportunidades para a comunidade científica interagir com Conferências como a RIO+20; b) as graves deficiências do ZeroDraft, documento produzido pela Divisão das Nações Unidas para o Desenvolvimento Sustentável para a RIO +20; c) o fato do foco de pesquisa dos três Programas de Pesquisa Ambiental da FAPESP - biodiversidade, bioenergia e mudanças climáticas - não estarem na pauta das discussões da RIO+20; d) que pouca ênfase é dada aos oceanos na Agenda da Conferência; e) em relação aos mecanismos de mercado associados com a transição para uma economia mais verde, a necessidade de enfatizar a redução de subsídios perversos e a promoção de incentivos econômicos para atividades ou processos de mitigação e/ou seqüestro de carbono; f) a necessidade de estimular o desenvolvimento e a consolidação da pesquisa na área de avaliação e valoração de serviços ambientais, no Brasil. Os participantes do Workshop reconheceram a necessidade de aprofundar o conhecimento sobre as convenções, tratados e acordos internacionais assinados e ratificados pelo Brasil, bem como as instituições internacionais, programas e iniciativas que promovem a participação da comunidade científica no debate de políticas ambientais globais. Finalmente, do ponto de vista dos três programas da FAPESP dois pontos foram destacados: a) que é imperativo aprofundar o conhecimento científico em cada uma das três áreas focais - biodiversidade, bioenergia e mudanças climáticas - porque é necessário aumentar a massa crítica de pesquisadores e do conhecimento para participar das discussões internacionais nessas áreas estratégicas; b) também é imperativo apoiar e promover projetos de pesquisa que integrem as áreas focais dos três programas, estimulando a constituição de equipes inter e transdisciplinares. Esta é uma tendência mundial na área das mudanças ambientais globais, e os participantes dos três programas sentem que podem dar uma contribuição significativa para o avanço do conhecimento, para o debate internacional e para a efetiva solução dos problemas.

The management of the São Paulo Metropolitan Area has as one of the challenges to bring a sustainable solution for land use in watershed protection areas, aiming at regional water resources protection. This paper has the objective to contribute to the discussion about Sustainable Development Strategy Assessment, from an analisys with focus at the environmental policies of the Santo André City - SP Brazil, in the context of water resources protection. For this, the proposal is to verify, based on the Bellagio Principles, the use of systemic approach, transparency, participatory process and social engagement in its policy formulation and implementation process. It was observed coherence within the policies, programmes and actions analysed, nevertheless, gaps were identified, which, within a strategic approach, means weakness for the construction of the local sustainability, as the lack of a consolidated sustainability indicators system.

This paper presents a power system capacity expansion planning modelconsidering carbon emissions constraints. In addition to the traditionaltechnical and economical issues usually considered in the planning process, two environmental policies that consist on the taxation and the annual limitsof carbon dioxide (CO 2) emissions are considered. Furthermore, the gradualretirement of old inefficient generation plants has been included. The approachguarantees a cleaner electricity production in the expanded power system ata relatively low cost. The proposed model considers the transmission systemand is applied to a 4-region and 11-region power systems over a 20-yearplanning horizon. Results show practical investment decisions in terms of sustainability and costs.

Indiscriminate and inappropriate use of pesticides in agriculture has been pointed out for increasing health problems and environmental damage. Considering that water resources are the principal destiny of those compounds after application, the present study presents optimization and validation of two simple and effi cient analytical methods for pesticides quantifi cation in both surface and groundwater. Were selected the pesticides more commonly used at Dourados (MS - Brazil), region with intense agricultural activity. Pesticides were preconcentrated by solid-phase extraction using C18 (500 mg) cartridges and then divided in two groups for elution and quantifi cation: 2.4-D and 2.4-DCP were eluted with methanol and quantifi ed by high performance liquid chromatography with ultra-violet detector (HPLC-UV) while atrazine, DIA, DEA, trifl uralin and methyl parathion were eluted with ethylacetate (1:1, v/v) and quantifi ed by gas chromatography with thermionic specifi c detector (GC-TSD). The methods showed satisfactory accuracy (76-107%) and precision (<12%) for the substances analyzed at the fortifi ed levels selected for the study, except for DIA (<51%). Study of pesticide stability also presented good results: C18 cartridges could be stored for at least for 21 days at -20ºC with no signs of the compounds degradability. Both methods limits of quantifi cation of the pesticides (0.22 - 0.48 μg L-1) are in accordance to the levels currently established by the Brazilian national legislation for pesticides in water. Although only the pesticide 2.4-D has been detected in two distinct collection points in the study period of time, this work warns for the requirement of systematical analysis of pesticides presence in water destined to human consume, principally in areas of intense agriculture activity. Such monitoring can provide subsidies for public environmental policies.

Historically the evolution of the occupation of ararense territory was due to the expansion of agricultural activities. Such activities were intensified with the transformations engendered by the Green Revolution, increasing the exploitation, the area occupied by agriculture and the deforestation and consequent environmental degradation. Therefore the current reality of rural areas in Araras/SP has shown that part of agricultural practices made it does not guarantee the effectiveness of environmental legislation and the sustainability of farms. Considering the recently implemented environmental policies, such as Law nº 12.651 / 2012, better known as New Forest Code and Decree nº 8.235 / 2014 establishing a period of one year to rural property registered with the Rural Environmental Registry (CAR), as tools targeting to reduce environmental degradation and contribute to building a sustainable rural development. This work aims to analyze the dynamics of the rural municipality of Araras on the environmental situation in some rural properties and actions to be taken by the owners to the full compliance of its properties before the environmental public policy

Stricter environmental policies are shown necessary to ensure an effective pollutant emission control. It is expected for the present year of 2015, that Brazil will assume, at the 21th United Nation's Climate Change Conference (COP21), implementation of commitment to a low carbon economy. This positioning affects the industrial environment, so that is deemed necessary to search for new technologies, less aggressive to the environment, so the adequacies to the new emission policies do not cause a negative effect on production. Almost all of the processes performed in the steel industry demand burning fuel and, therefore, flue gases are sent to the atmosphere. In this present work is discussed the utilization of heat exchangers so, by recovering part of the available heat from the flue gases of certain industrial process, the combustion air is preheated. The combustion air preheat results in less energy requirement, i.e., less need of fuel consumption and, in addition, minor amount of pollutants to be emitted. Due to better fitting to the process, it is studied the utilization of spiral plate heat exchangers. The heat exchanger dimensioning is made by an iterative method implemented in the software Microsoft Excel. Subsequently are analyzed the gains in terms of process's thermal efficiency improvement and the percentage of fuel saving. The latter implies in reduction of the same percentage of greenhouse gases emission
