- A new model for EEZ surveillance and management in PortugalPublication . Melo, João Joanaz dePortugal has an EEZ of 1.6 million square kilometres. The importance of the EEZ is primarily related to economic activities such as fisheries and tourism, and eventually offshore mining; but also to broader issues such as environment, internal security and geo-strategy. Maritime surveillance is a keystone for the control of the EEZ. The authors discuss strengths and flaws of the Portuguese maritime surveillance scheme, plus opportunities for better management of the EEZ. Maritime surveillance has not been a priority in Portugal, hence available means are insufficient; the responsibilities of a maritime authority are distributed among several institutions, relatively low on State hierarchy and with inadequate co-ordination. Although the essential functions of a maritime authority are performed, efficiency is poor and existing means are not used to full capacity. EEZ management exists only as desegregated policies. The authors adopt the twin concepts of the integrated management for the EEZ; and the Command, Control, Communications and Intelligence (C3I) for the maritime surveillance. A model is proposed to integrate such concepts into the new VTMIS (Vessel Traffic Management Information Services) about to be implemented in Portugal. This should improve the VTMIS and the efficiency of other means of maritime surveillance and management. The new system should have a strong geographical information component and the capability to integrate on-line information from many sources (such as land-based radar, port information, satellite imagery, military and police routine surveillance, international databases and mathematical modelling, among others). Such information would then be used for a number of tasks, including environmental protection and natural resources management in the EEZ. The paper discusses the desirable specifications for such a system and its link with existing and future institutional arrangements in Portugal.
- Alqueva: alegrias e frustrações da mais emblemática obra pública portuguesa do séc. XXPublication . Melo, João Joanaz deAlqueva é um dos maiores empreendimentos já realizados em Portugal. É certamente o mais polémico, o mais emblemático deste estilo de desenvolvimento, o causador de maiores impactes ambientais e de mais medidas para a sua mitigação, num século XX recheado de obras públicas mais ou menos problemáticas. Alqueva tem sido defendido apaixonadamente por uns como um empreendimento estratégico e estruturante para o desenvolvimento do Alentejo, e atacado com igual paixão por outros como um elefante branco com impactes inaceitáveis. Alqueva foi também um dos casos que mereceu maior atenção e envolvimento por parte do movimento ambientalista português. Quase sete anos depois da inauguração da barragem de Alqueva, vale a pena fazer um balanço dos resultados.
