The role of maritime transportation within international trade was drastically revamped during the inception of the globalization process, which enhanced the contribution of ports in world economy as main logistics gateways for global production and trade. As a result, the relationship between ports and governments has changed. Devolution ideologies that had been applied in other industries decades ago were now being considered by governments for the port industry. Many central governments sought to extract themselves from commercial activities of ports and devolving this responsibility to local governments, communities or private entities. The institution of devolution programs also changed the governance structures of ports further influencing port performance. Consequently, the recent worldwide trend towards devolution in the port industry has spawned considerable variety of governance models that are now set in place around the world. While some countries opt for more decentralized structures others prefer to retain a centralization of powers. In this way some governments consider local features and national integration more than others, which ultimately influence the success of a port reform implementation. Nevertheless, the prime intent of governments is now to maximize the efficiency and performance of their domestic ports. This issue intends to examine the changed port governance environment in Brazil by determining how and why imposed port reforms of the Brazilian federal government have been affecting the overall performance of the national port system, over the last decades, using the Port of Santos as a sample upon an exploratory study. For that, the study will use a contingency theory-based framework – the Matching Framework - that views port performance as a function of the fit among the dimensions of external operating environment, strategy and structure of a port organization. In essence, the greater the fit among these dimensions the better the expected performance of a port will be, and vice-versa. Port managers, government officials and academics alike shall be interested in this document.

A dragagem dos sedimentos do Canal de Santos é necessária para permitir o trânsito de navios que operam no Porto de Santos. As áreas de disposição do material dragado estão situadas na zona costeira, em frente à Baía de Santos. Este estudo visou avaliar a qualidade dos sedimentos do Canal de Santos e das áreas de disposição atuais e antigas, utilizando testes de toxicidade de sedimento integral com anfípodos e de toxicidade de elutriatos com embriões de ouriço do mar. As amostras do Canal de Santos foram consideradas as mais tóxicas: todas as amostras dessa área foram consideradas significativamente tóxicas. Além disso, algumas amostras das áreas de disposição exibiram toxicidade. Os resultados mostraram, portanto, que os sedimentos apresentam evidências de degradação em sua qualidade, porém novos estudos devem ser conduzidos visando determinar as relações entre contaminação e toxicidade. Os resultados sugerem ainda que a disposição dos sedimentos dragados deva ser reavaliada.

Sediment contamination by metals poses risks to coastal ecosystems and is considered to be problematic to dredging operations. In Brazil, there are differences in sedimentology along the Large Marine Ecosystems in relation to the metal distributions. We aimed to assess the extent of Al, Fe, Hg, Cd, Cr, Cu, Ni, Pb and Zn contamination in sediments from port zones in northeast (Mucuripe and Pecem) and southeast (Santos) Brazil through geochemical analyses and sediment quality ratings. The metal concentrations found in these port zones were higher than those observed in the continental shelf or the background values in both regions. In the northeast, metals were associated with carbonate, while in Santos, they were associated with mud. Geochemical analyses showed enrichments in Hg, Cd, Cu, Ni and Zn, and a simple application of international sediment quality guidelines failed to predict their impacts, whereas the use of site-specific values that were derived by geochemical and ecotoxicological approaches seemed to be more appropriate in the management of the dredged sediments.

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.
