Economic restructuring, social re-composition and recent urban changes in Portugal

The productive restructuring process has affected more than just the economic field, because its effects have been felt on urbanisation processes, on social relations, and on the spatial organisation of society. Starting from the ‘metapolis’ concept, developed by Ascher (1995), we analyse the evolution of new forms of urban space in Portugal, arguing that new urban forms generate new social inequalities and, in extreme cases, social exclusion. Portugal is a semi-peripheral country that combines certain of the trends in social and economic organisation common to core countries, with certain trends more common in the developing world. Thus the understanding of urban change in Portugal is a complex task, made more difficult by the rapidity of processes since the mid 1970s. The Lisbon Metropolitan Area has been deeply affected by the productive restructuring process. The role of economic and urban policies in the Lisbon region is discussed, and an assessment is made of certain measures aimed at solving economic and social problems.

Characteristics of post-socialist urban transformation in East Central Europe

The development of the post-socialist city has already been characterised by substantial restructuring processes. Particular emphasis should be drawn to the take-off of the tertiary sector and the comprehensive blight phenomena in the previously industrial areas. The urban housing sector has witnessed increasing housing affordability problems, a marginalisation of communal housing stock, an increase of segregation and an intensification of the decay in the old housing stock. In all East Central European states the spatial development processes of industry and services within the cities basically show clear parallels to the pattern of urban development in continental Europe. In Hungary housing policy, tenure structure and the level of segregation already show relatively closer similarities to the neoliberal, Anglo–American pattern of development. The other ECE states show closer similarities to the corporatist welfare states of continental Europe. As far as medium-term urban development in East Central Europe is concerned, it is to be assumed that – regardless of the specific path of further development – overall solutions shall not be found for the fundamental problems which are the legacy of the socialist era – the decay of old housing stock, large scale derelict industrial areas and the extent and deficiencies of high-rise housing estates.

Something in the Air: Civic science and contentious environmental politics in post-apartheid South Africa

The emergence of an environmental movement in post-apartheid South Africa has involved the reframing of the environment as a ‘brown’ issue, articulating the discourse of social and environmental justice and a rights-based notion of democracy. Environmental movements have pursued a dual strategy of deliberation and activist opposition. Environmental movements have deployed science to pursue the strategic task of democratic opposition and have established networks of environmental knowledge and expertise. Ecological modernization is the dominant approach to environmental governance and adopts a science-based policy approach. In this context the regulation and management of the environment is premised on the need for science, which provides the authoritative basis for a regulatory response. In local environmental movements, there exists a fundamental tension between a cumulative history of lay knowledge about pollution and the lack of official acknowledgement of qualitative narratives. This is accompanied by a lack and suspicion of reliable official data. Environmental movements have thus employed ‘civic science’ strategically to place the issue of air pollution on the political agenda. This paper uses the case of environmental politics in Durban to reflect on the ways in which civic science and lay knowledge, together constituting community hybrid knowledge, are produced and disseminated in order to pressure the state and capital. The three ways in which knowledge is deployed are: to frame environmental problems, in strategies of oppositional advocacy, and in deliberative policy forums. Empirical analysis shows that civic science is produced through knowledge networks, and both lay knowledge and civic science are opportunistically used by environmental movements to engage both inside and outside formal policy making arenas. This deployment of hybrid knowledge by environmental movements represents a broader challenge to the power of science and technology based on increasing evidence of the hazards and risks facing ordinary people in their daily lives.     

To the market and back: Housing policy and state housing in New Zealand

Housing policy in New Zealand has traditionally been characterised by significant market intervention in support of home ownership and a residual state housing rental sector. Within the context of dramatic social welfare reforms in the 1990s, a set of radical housing reforms was introduced that profoundly transformed the role of the state in the housing system. Key elements of the reforms included the creation of a profit-oriented company to manage state rentals, a move to market rents in the state sector and the introduction of an accommodation supplement. This paper examines the underlying rationale and impacts of the reforms focusing on issues of privatisation, tenant turnover, affordability and tenant protest. Having examined the ongoing problems engendered by these reforms the paper reviews more recent political and legislative reforms that were sought to reassert the state's traditional position within the New Zealand housing market.

Late Quaternary glaciation in Southern Africa: moraine ridges and glacial deposits at Mount Enterprise in the Drakensberg of the Eastern Cape Province,South Africa

Late Quaternary moraines and diamictons containing striated clasts are described from near Elliot in the Drakensberg of South Africa. An equilibrium line altitude (ELA) of 2109 m is suggested for the palaeoglacier associated with the innermost moraine. This glacier was fed by a very extensive snowblow area and the ELA may reflect the temperature–precipitation–wind ELA rather than the temperature–precipitation ELA and be considerably below the ‘regional’ ELA. Mean annual air temperatures when glaciation occurred were probably at least 10.0°C below those of the present. Copyright © 2001 John Wiley & Sons, Ltd.     

Moving young lives: Mobility, immobility and inter-generational tensions in urban Africa

This paper explores young people’s experiences and perceptions of mobility and mobility constraints in poorer urban areas of Ghana, Malawi and South Africa within the specific context of inter-generational relations. Drawing principally on qualitative research findings from a study involving both adult and child researchers, our aim is to chart the diversities and commonalities of urban young people’s mobility experiences in the everyday - how they use and experience the city - developing a comparative perspective across three urban study sites which links young people’s mobility with the power relations that operate to shape their movements in individual locations. In particular, we consider how positive and negative images of young people’s mobility play out in terms of the inter-generational frictions and negotiations generated by their mobility performances. We also reflect on the developmental implications, in terms of young people’s access to services and income and their participation in the social networks and peer culture which may shape their life trajectories. Three themes are explored in detail: mobility as challenge, mobility as temptation and mobility control.     

Urban environmental services and the state in East Africa; between neo-developmental and network governance approaches

Although governments are generally expected to provide environmental services such as sanitation and solid waste collection for their citizens, most (municipal) governments in Sub-Saharan Africa seem hardly able to take up this task. Without ignoring the lack of material resources resulting from poverty, there are other structural causes for this failure as well and related to the role of the state. Since independence, the state in Africa has been debated in political as well as in academic circles and opposing views can still be discerned today. While some promote a strong interventionist state which can effectively enhance development, others consider introducing network governance by involving various societal actors in combination with different levels of government a more promising alternative. After presenting an historical overview, in this paper I will summarize this debate and discuss future options for East African authorities for providing more effective and sustainable urban environmental infrastructures and services.     

Climate change transformation: A definition and typology to guide decision making in urban environments

Climate change presents a threat to the sustainability of cities and their societies, and must be adequately addressed. Urban environments (cities) are responsible for the creation of a significant amount of greenhouse gas emissions which are the source of climate change. Cities have been increasingly the focus of action to address climate change, yet emissions are not significantly reducing. Additionally, there a lack of integration between adaptation and mitigation. This prevents responses adequate to limit global warming to 1.5^OC, and to be well adapted to anticipated changes. This paper critically analyses existing definitions and typologies of climate change actions. A definition of ‘climate change transformation’ is proposed which includes the integration of adaptation and mitigation goals to enable a new regime in which global warming is limited to 1.5^OC. A new three-part typology: ‘coping, malaction and transformation,’ is presented for categorising climate change actions by the extent to which they integrate adaptation and mitigation, and define a new regime. The typology is accompanied by illustrations to demonstrate the relationship between adaptation and mitigation. The definition, typology and illustration serve to guide effective climate change decision making, and provides principles to guide application in urban environments.
