Book Description
The aim of this occasional paper is to gain a better understanding of urban agriculture within the green infrastructure network in the City of Johannesburg and to identify the range of ecosystem services that could be delivered when maintaining and investing in these assets. The analysis in this paper adopts a multi-method approach to (1) identify the interlinkages between urban agriculture and social, economic and environmental systems in the City of Johannesburg; (2) validate these critical interlinkages with stakeholder input and ground-level experience of urban agriculture; and (3) visualise these interlinkages through a spatial analysis of food gardens in the City of Johannesburg.

Book Description
In the context of heightened climate variability, thinking about ways to redesign our urban areas with more sustainable infrastructure solutions is becoming more and more important. Green infrastructure (GI) is emerging as an alternative approach to traditional (‘grey’) infrastructure in urban planning and development. Its emergence can be understood in terms of the growing demand for infrastructure and services, increased concerns over natural resource constraints and climate change, and the negative impacts associated with traditional approaches to designing and building cities. It has been proposed that GI can provide the same services as traditional infrastructure at a similar capital cost, while also providing a range of additional benefits. However, despite the increasing examples of successful urban GI applications, traditional infrastructure continues to dominate due to the lack of systematic evidence to support GI implementation. As a result, there has been an increase in calls from policy- and decision-makers for a greater evidence base on the benefits of GI, as well as for practical guidelines on its implementation. ‘Towards applying a green infrastructure approach in the Gauteng City-Region’ is the GCRO’s third report in its ongoing research into 'Green assets and infrastructure'. The first two reports in this project series were more theoretically grounded and policy-oriented, whereas this third report is more practical in nature. The first report explored the basic principles around GI, assessed the extent of ecological features in Gauteng and the way governments in the province think about planning and maintenance of green assets. The second report responded to some of the challenges identified in the first report, and in particular the importance of government officials and practitioners in exploring how international green infrastructure plans could be applied in the Gauteng context. This third report builds on the findings of the aforementioned reports and the project’s CityLab series, which highlighted the need to build an evidence base as critical for garnering support for and as well as enhancing investment in the GI approach. Unlike the more theoretically grounded earlier reports, this report comprises four technical sections and practical reflections on how a GI approach could be incorporated into urban planning in the GCR and in other similar urban contexts.

Book Description
As the population, economy and urban built environment in the Gauteng City-Region (GCR) expand, government is increasingly under pressure to provide urban infrastructure to support growth. It is increasingly important that this infrastructure is sustainable, minimising the negative environmental impacts often associated with traditional forms of urban development. Green Infrastructure (GI) is the interconnected set of natural and man-made ecological systems, green spaces and other landscape features that provide services and strategic functions in the same way as traditional infrastructure. In harnessing the benefits of ecosystem services, GI has emerged as a more efficient, cost effective and sustainable alternative – and sometimes accompanying approach – to conventional forms of infrastructure. Despite international evidence demonstrating how GI can be used as an alternative to, or in tandem with, traditional infrastructure, the GI approach has so far gained only limited traction in the GCR. In 2013 the GCRO published the State of Green Infrastructure in the GCR report. The report established the principles that underpin GI, used available data to map the extent of GI networks in the region, assessed to what extent municipalities were aware of and applying a GI approach, and demonstrated a possible way to value GI in local government financial systems. The conclusions of the State of Green Infrastructure report were used to guide the next phase of GCRO’s research in support of the adoption of GI approach – a phase focused on better understanding the opportunities for implementing GI in planning and infrastructure development programmes and on addressing some of the challenges associated with shifts towards this approach. A framework for a green infrastructure planning approach in the Gauteng City-Region, GCRO’s fourth Research Report, builds on the foundations laid in the State of Green Infrastructure report. It assembles expert inputs and reflections from collaborative stakeholder discussions in what was known as the Green Infrastructure CityLab to illustrate important considerations for the development of a GI planning approach in the Gauteng City-Region (GCR). The report is divided into three broad sections. Part A introduces the theoretical underpinnings of a GI approach and builds an argument for the importance of incorporating GI into planning and infrastructure development in the GCR. Part B presents three pieces written by external experts. They consider how GI and ecosystem services can be valued by municipalities, and how so-called ‘grey-green’ infrastructure design solutions can be implemented in the GCR. Part C reflects on the stakeholder engagement process that has been undertaken, primarily through the GI CityLab, to deepen understanding of how GI can be embedded in municipal practice. Based on these research findings, this report concludes with a strategy for GCRO’s next phase of work in its ongoing Green Assets and Infrastructure Project.

Book Description
Grouping a selection of papers from the 12th International Conference on Urban Regeneration and Sustainability, this book refers to all aspects of urban environment and provides solutions that lead towards sustainability. The series maintains its strong reputation and a substantial number of contributions have been made from a diverse range of transnational delegates, resulting in a variety of topics and experiences. Urban areas face a number of challenges related to reducing pollution, improving main transportation and infrastructure systems and these challenges can contribute to the development of social and economic imbalances and require the development of new solutions. The challenge is to manage human activities, pursuing welfare and prosperity in the urban environment, whilst considering the relationships between the parts and their connections with the living world. The dynamics of its networks (flows of energy matter, people, goods, information and other resources) are fundamental for an understanding of the evolving nature of today’s cities. Large cities represent a productive ground for architects, engineers, city planners, social and political scientists able to conceive new ideas and time them according to technological advances and human requirements. The multidisciplinary components of urban planning, the challenges presented by the increasing size of cities, the amount of resources required and the complexity of modern society are all addressed. The published papers cover the following fields: Urban strategies; Planning, development and management; The community and the city; Infrastructure and society; Eco-town planning; Spatial conflicts in the city; Urban transportation and planning; Conservation and regeneration; Architectural issues; Sustainable energy and the city; Environmental management; Flood risk; Waste management; Urban air pollution; Health issues; Water resources; Landscape planning and design; Intelligent environment; Planning for risk and natural hazards; Waterfront development; Case studies.

Book Description
Against the background of unprecedented rates of urbanisation in the Global South, leading to massive social, economic and environmental transformations, this book engages with the dire need to understand the ecology of such settings as the foundation for fostering sustainable and resilient human settlements in contexts that are very different to the Global North. It does so by bringing together scholars from around the world, drawing together research and case studies from across the Global South to illustrate, in an interdisciplinary and comprehensive fashion, the ecology of towns and cities in the Global South. Framed using a social-ecological systems lens, it provides the reader with an in-depth analysis and understanding of the ecological dynamics and ecosystem services and disservices within the complex and rapidly changing towns and cities of the Global South, a region with currently scarce representation in most of the urban ecology literature. As such the book makes a call for greater geographical balance in urban ecology research leading towards a more global understanding and frameworks. The book embraces the complexity of these rapid transformations for ecological and environmental management and how the ecosystems and the benefits they provide shape local ecologies, livelihood opportunities and human wellbeing, and how such knowledge can be mobilised towards improved urban design and management and thus urban sustainability.

Book Description
At present there are a great number of urban interventions taking place within the Gauteng City-Region, including transport and area-based upgrading projects (Corridors of Freedom/Transit Oriented Development), mega-human settlements, inner-city renewal schemes, and the establishment of City Improvement Districts (CIDs) in various locations. As they are envisioned, planned and implemented, all of these projects will make significant alterations to the urban fabric. It is therefore crucial that research engages with these processes and captures their dynamics, contradictions, contestations and outcomes. This Occasional Paper contributes to this endeavour by examining how two very different area-based management and urban upgrading projects have been imagined and executed. The report comprises a case-study of the expanding Ekhaya precinct in Hillbrow, a densely populated, economically stressed inner-city neighbourhood, and the development of a precinct plan in Norwood, a middle-class suburb situated to the north of the inner-city. Ekhaya is a Residential City Improvement District (RCID) and was an intervention led primarily by private, commercial developers. The Grant Avenue Precinct Plan (GAPP), in contrast, was initiated by local government as part of broader efforts to manage change and facilitate residential intensification and improved inclusion in the suburb. Comparing and contrasting approaches in two vastly different sub-local areas gives an opportunity to explore the varying actors; governance arrangements; urban upgrading ambitions and ideals; resources, practices, mechanisms and infrastructures; alliances and partnerships; and compromises and experiments that are assembled at the neighbourhood scale to bring urban upgrading interventions to fruition. The paper also draws particular attention to the fault lines, points of divergence, and conflicts in the two settings, and how these frequently hinder or frustrate efforts at urban improvement. The Occasional Paper is divided into three main sections. The first section, ‘Conceiving neighbourhoods’, outlines the visions and ideals that have shaped neighbourhood formation, planning processes and urban upgrading initiatives in the two case-study sites. It shows that Johannesburg’s vastly unequal landscape hinders the articulation of a single, unified vision for the city. Improvement in Hillbrow has entailed dealing with day-to-day deprivations, service delivery failings and deficits in basic urban management. The visions that informed urban regeneration in the Ekhaya RCID are therefore relatively mundane, but are capable of bringing about significant improvements to the area, as well as to the lives of its residents. In contrast, the visions behind the precinct strategy for Norwood were far more ambitious as they aimed at generating drastic change in the suburb’s built environment and social landscape. However, various socio-economic challenges – financial constraints, organised opposition from affluent residents and lack of support from the private sector – have rendered these broad ambitions unattainable. The second section, ‘Producing neighbourhoods’, examines the various tactics, strategies, planning mechanisms and material objects that were used to bring visions to life and give form to the two neighbourhood improvement schemes. For example, it explores how different security infrastructures mobilised in the Ekhaya RCID have defined the neighbourhood and separated it from the general disorder and decay that characterise the wider Hillbrow area. While these infrastructures have had significant effects on the neighbourhood, and contributed to improved feelings of safety, they have also introduced inequality – as the area has come to enjoy improved levels of policing and safety, crime has been displaced to surrounding neighbourhoods yet to attract private investment. The section further shows that while physical infrastructure is important, it is not sufficient to generate neighbourhoods and associational life. Rather, the realisation of visions for improved forms of belonging and social cohesion rely on the creation of social networks, and opportunities for socialisation and shared recreation. Highlighting experiences of upgrading two parks, Ekhaya Park in Hillbrow and Norwood Park, this section emphasises the importance of public space, and the shared ideals and commitments to social inclusion that should inform planning processes and urban interventions at the local level. However, the section also documents the prejudices and exclusionary attitudes that frequently emerge during such processes. The third section, ‘Managing neighbourhoods’, describes the institutional arrangements, day-to-day activities, forms of partnership and adaptive strategies being used to sustain urban interventions and regulate neighbourhoods. It investigates contrasting viewpoints and approaches to dealing with various urban challenges, particularly the role and place of informal activities in the two neighbourhoods. In Hillbrow, the official position is that informal trading is not permitted. However, in reality, actors with degrees of authority and power in the area have recognised the need to be tolerant towards people engaged in such practices, and frequently cooperate with some informal traders. The section therefore shows that urban governance requires the formation of arrangements and partnerships of convenience at the sub-local level, and that adaptive, flexible urban management practices are required, particularly in stressed neighbourhoods characterised by high levels of poverty. In contrast, although the official plans formulated for the GAPP stipulated that vulnerable groups such as homeless people, car guards and informal traders were to be protected, in reality, intolerant attitudes were evident and powerful residents and businesses used a variety of tactics to marginalise these groups and attempt to remove them from the area. The section therefore shows how everyday power and resource differentials can often supersede or subvert good intentions towards inclusivity – the realisation of visions for urban improvement unavoidably seems to generate new forms of exclusion that planners, officials and civil society need to be aware of.
