摘要

The term brownfield is generally used to describe both spatially and formalistically everything from polluted industrial landscapes to former factory buildings, including vacant or abandoned properties usually found in older, declining sections of a city. This fact, is increasingly considered an important set back in understanding the variability existing within the different landscapes generally typified as brownfields, contributing somehow to prevent their regeneration and augmenting the length of time land is vacant or underutilized. In fact, though poorly assessed, this circumstance reveals one of the main questions that those aiming to work in brownfield transformation have to deal with, which is the relevance of understanding their characteristics and different typologies (abandoned land, contaminated land, derelict land, underutilized land and vacant land), as a means of achieving a consistency that enables the creation of new methodologies and frameworks to deal with the redevelopment of these spaces. In this regard, this research presents a critical review of the information on brownfield redevelopment, considering not only the use of existing literature but also the analysis of twenty-five brownfield redevelopment projects, in order to identifying on the one hand, the existing brownfield typologies, and on the other hand the benefits associated to each of the identified brownfield typologies. Considering the objectives of the research, expert participation was introduced as a crucial element of the processes, throughout the use of email and internet surveys, that enabled not only the collection of information regarding their level of agreement towards different brownfield typologies, but also their view on the benefits associated with each one of the identified typologies. The collected data enabled us to conclude that even if the redevelopment of the different brownfield typologies have direct and indirect benefits at different dimensions, they are very diverse influencing society and citizens' life's quality on different ways. The performed analysis showed that according to experts' perspectives, while the transformation of derelict land is the brownfield typology which brings more benefits on the defined identified dimensions, with special impact on infrastructure, economy, community, ecology and health, the development of vacant land, though equally important, is the one that has less benefits to society, since its benefits are felt mainly on community and recreational dimensions. When analyzed independently, the obtained results might give designers, planners and decision makers valuable information on the benefits associated to each of the five brownfield typologies identified throughout this research, enabling them to better decide on which sites to developed first, considering not only the objectives behind the development, but also the different dimensions positively affected by the redevelopment.
