Na economia dos transportes estudam-se os mercados, no seu desempenho em tempo, na interação com o espaço e nos reflexos externos, num contexto de possível regulação e sob o objetivo de uma mobilidade sustentável. Esta deverá ser infra-máxima, a um preço moderador do consumo. O transporte é um importante sector e empregador. Cresce com a economia e contribui para que se cresça mais. É um elemento relevante da despesa das famílias e de Investimento. Permite o comércio, com consequências para a organização interna, regional e mundial da produção. Altera padrões de localização de empresas, pessoas e aglomerados urbanos, bem como estilos de vida. Gera externalidades positivas, aproximando ideias e mercados, mas é também um poluidor; o congestionamento é outra externalidade a lesar desempenho, procura e custos, sempre condicionados pelo tempo. As pessoas usam mais o automóvel. Nas mercadorias, dominam o navio e o camião. Também se abordam os projetos de infra-estruturas e as políticas.

Reflecting the very latest research, this book provides an in-depth review of the role of resilience in the management of social-ecological systems and the ecosystem services they provide. Leaders in the field outline seven principles for building resilience in social-ecological systems, examining how these can be applied to advance sustainability.

There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.

Traditional transport planning has generated transport systems that propagate an unfair distribution of accessibility and have environmental and safety issues. This book highlights the importance of social and political aspects of transport policy and provides a methodology to support this approach. It emphasizes the importance of co-ordinating urban, transport and traffic planning, and addresses the major challenge of modifying the building and use of roads. The author makes suggestions for innovative and radical new measures towards an equitable and sustainable urban environment.

Once one of the world's largest staple food producers, Angola is now known as a major oil exporter - the second largest producer in sub-Saharan Africa. Angola is also the world's fourth largest producer of rough diamonds in terms of value, with the potential to become one of the leading global diamond producers. In addition to oil and diamonds, the country is well endowed with agricultural resources which remain mostly untapped. However, despite the country's significant natural wealth, a prolonged civil war, the rapid development of the oil sector, and the policies pursued after Independence in 1975 have left the Angolan economy in a unique situation, characterized by very uneven indicators of development. The Angolan economy is now experiencing massive oil windfall gains that are expected to last throughout the next decade. Since oil rents are to a large part concentrated in the public sector, the question of how the oil revenue should be spent and distributed across present and future generations becomes key to any economic development strategy. This study identifies six core areas where a strategic approach for the development of a broad-based growth strategy is required: (i) the incomplete transition to a market economy; (ii) macroeconomic management; (iii) governance and transparency in the management of the mineral wealth; (iv) the business environment; (v) agriculture; and (vi) public service delivery to the poor.

For many women in developing countries, such as sub-Saharan Africa, south and south-east Asia, and central and south America, there is a high risk of cervical cancer, but a lack of effective programmes to detect and treat such a problem. This introductory manual is intended to simply the learning of colposcopy (a diagnostic and evaluation method for cervical intraepithelia neoplasia, or cervical cancer).
