The Lagunya Lacuna : contestations of legitimacy and agency in housing allocation in a Black Local Authority, 1983-1994

Word processed copy.Includes bibliographical references (leaves 159-175).In this thesis I draw on experiences in a particular neighbourhood within the Lagunya townships, New Crossroads, in order to examine the realities of local government housing administration at the local scale. The New Crossroads housing allocation process illustrates the insider/outsider polemic and the ways in which complex interrelationships developed between the local authorities and the community leadership structures, between the New Crossroads community and the residents of townships surrounding them, and among the residents of the New Crossroads community themselves. Such interactions speak to the ways in which both state and community actors adopted multiple and sometimes-dissimilar identities in order to access resources such as housing and to navigate the highly politicised terrain of the townships during the BLA era

Inserting rights and justice into urban resilience : a focus on everyday risk

Resilience building has become a growing policy agenda, particularly for urban risk management. While much of the resilience agenda has been shaped by policies and discourses from the global North, its applicability for cities of the global south, particularly African cities, has not been sufficiently assessed. Focusing on rights of urban citizens as the object to be made resilient, rather than physical and ecological infrastructures, may help to address many of the root causes that characterize the unacceptable risks that urban residents face on a daily basis. Linked to this idea, we discuss four entry points for grounding a rights and justice orientation for urban resilience. First, notions of resilience must move away from narrow, financially-orientated risk analyses. Second, opportunities must be created for “negotiated resilience”, to allow for attention to processes that support these goals, as well as for the integration of diverse interests. Third, achieving resilience in ways that do justice to the local realities of diverse urban contexts necessitates taking into account endogenous, locally situated processes, knowledges and norms. And finally, urban resilience needs to be placed within the context of global systems, providing an opportunity for African contributions to help reimagine the role that cities might play in these global finance, politics and science processes

Collaborative risk governance in informal urban areas : the case of Wallacedene temporary relocation area

CITATION: Zweig, P. J. 2017. Collaborative risk governance in informal urban areas : the case of Wallacedene temporary relocation area. Jamba: Journal of Disaster Risk Studies, 9(1):a386, doi:10.4102/jamba.v9i1.386.The original publication is available at http://www.jamba.org.zaCommunity-based disaster risk management (CBDRM) is an emancipatory approach that aims to empower local communities in reducing their own risks. A community risk assessment (CRA) is an essential element of CBDRM, incorporating highly participatory processes of hazard identification and vulnerability analysis. By incorporating local knowledge and insights, together with those contributed by other external role players, the nature of local risks can be more accurately identified, giving consideration to their causal factors, the nature of their realised impacts or potential effects on a local community and the challenges posed in addressing them. Reflecting on the process and outcomes of a CRA conducted in an informal settlement in the Cape Town metropolitan area, this article describes how one such risk assessment contributed to building local agency through a process of collaborative engagement. Offered as an example of possible best practice, it illustrates both the immediate and potentially longer term benefits to be derived from such a collaborative process, suggesting that a community-based risk assessment may contribute significantly to building more resilient communities. It concludes with a consideration of the challenges of sustaining longer term risk reduction efforts.https://jamba.org.za/index.php/jamba/article/view/386Publisher's versio

Everyday hazards and vulnerabilities amongst backyard dwellers : a case study of Vredendal North, Matzikama Municipality, South Africa

CITATION: Zweig, P. J. 2015. Everyday hazards and vulnerabilities amongst backyard dwellers : a case study of Vredendal North, Matzikama Municipality, South Africa. Jamba: Journal of Disaster Risk Studies, 7(1):8 pages, doi:10.4102/jamba.v7i1.210.The original publication is available at http://www.jamba.org.zaThe populations of many small towns in South Africa continue to expand unmatched by parallel economic growth, entrenching high levels of poverty. The town of Vredendal, located close to the national route between Namibia and Cape Town in South Africa, is a West Coast development node and an emergent industrial and processing area that continues to attract an influx of people seeking economic opportunities. This is challenging the capacity of the local municipality, which has a waiting list for state-provided low-cost housing units, whilst the provision of adequate infrastructure to meet growing local need is also a developmental concern. In the suburb of Vredendal North this has resulted in the proliferation of unplanned informal dwellings in the backyards of formalised low-cost housing areas. Largely overlooked by urban researchers, little is known or understood about small town backyard populations. This prompted a brief study of Vredendal North backyard dwellers commissioned by the local municipality to identify their everyday hazards and livelihood vulnerabilities to inform future development planning. A community workshop identified critical development needs and suggested that backyard dwellers in small towns experience similar living conditions and hazards to those in the cities, although underlain by some unique differences.http://www.jamba.org.za/index.php/jamba/article/view/210Publisher's versio

Fire safety engineering guideline for informal settlements : towards practical solutions for a complex problem in South Africa

CITATION: Walls, R. (ed.). 2020. Fire safety engineering guideline for informal settlements: Towards practical solutions for a complex problem in South Africa. Stellenbosch: FireSUN Publications.ENGLISH ABSTRACT: Informal settlements are growing rapidly, and in Africa they are likely to double in size within the coming few decades. Informal settlements (IS) (also known by names such as slums, ghettos, favelas and shantytowns) are typically dense, and people’s homes are built from highly combustible materials. Hence, when a fire breaks out it can spread rapidly, leaving thousands homeless. Every year in South Africa fires are affecting large numbers of people, costing municipalities millions of rands (ZAR), and are severely hindering the upliftment of the poorest in our communities. This guideline seeks to provide a holistic approach to improving fire safety for communities. It is important to realise that this complex problem can only be improved by a multi-sectoral response addressing various issues such as: reducing the risk of ignition, providing early warning systems, having community involvement, having well-resourced and well-prepared fire departments, reducing the combustible nature of homes, and many other similar factors. The audience of this report is broad in that it seeks to assist fire departments, local municipalities, national government, engineers, town planners and non-governmental organisations involved in IS fire safety. This work initially provides an understanding of communities living in settlements, as often interventions overlook the daily reality of these people which leads to interventions being ineffective. Fire behaviour, fire spread and fire safety engineering is then discussed, and it is shown how this can be applied to ISs. This is done to dispel many common myths, and to show what can, and can’t, improve fire safety. To understand IS fire incidents a timeline of a typical fire incident is provided, along with a case study on the 2017 Imizamo Yethu disaster. Many interventions, strategies and devices are discussed, looking at what could be adopted to improve fire safety. It is important to realise that a basket of solutions is typically needed, and a single intervention may have a very limited impact. A list of tasks that communities can undertake before, during and after a fire incident provides a useful resource for organisations working with communities. Ultimately there is no easy solution to this problem. However, through a concerted, evidence-based approach significant fire safety improvements can be made to help the poorest in our land.publishers versio

Microbiota determines insulin sensitivity in TLR2-KO mice

Environmental factors have a key role in the control of gut microbiota and obesity. TLR2 knockout (TLR2(-/-)) mice in some housing conditions are protected from diet-induced insulin resistance. However, in our housing conditions these animals are not protected from diet-induced insulin-resistance. Aim: The aim of the present study was to investigate the influence of our animal housing conditions on the gut microbiota, glucose tolerance and insulin sensitivity in TLR2(-/-) mice. Material and methods: The microbiota was investigated by metagenomics, associated with hyperinsulinemic euglycemic clamp and GTT associated with insulin signaling through immunoblotting. Results: The results showed that TLR2(-/-) mice in our housing conditions presented a phenotype of metabolic syndrome characterized by insulin resistance, glucose intolerance and increase in body weight. This phenotype was associated with differences in microbiota in TLR2(-/-) mice that showed a decrease in the Proteobacteria and Bacteroidetes phyla and an increase in the Firmicutesphylum, associated with and in increase in the Oscillospira and Ruminococcus genera. Furthermore there is also an increase in circulating LPS and subclinical inflammation in TLR2(-/-). The molecular mechanism that account for insulin resistance was an activation of TLR4, associated with ER stress and JNK activation. The phenotype and metabolic behavior was reversed by antibiotic treatment and reproduced in WT mice by microbiota transplantation. Conclusions: Our data show, for the first time, that the intestinal microbiota can induce insulin resistance and obesity in an animal model that is genetically protected from these processes234CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPsem informaçãosem informação465693/2014-8We also acknowledge the financial support INCT de Obesidade e Diabetes 465693/2014-8 (FAPESP) and CAPES/CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico)

Oral Glutamine Supplementation Reduces Obesity, Pro-Inflammatory Markers, and Improves Insulin Sensitivity in DIO Wistar Rats and Reduces Waist Circumference in Overweight and Obese Humans

In the present study, we aimed to investigate whether chronic oral glutamine (Gln) supplementation may alter metabolic parameters and the inflammatory profile in overweight and obese humans as well as whether Gln may modulate molecular pathways in key tissues linked to the insulin action in rats. Thirty-nine overweight/obese volunteers received 30 g of Gln or alanine (Ala-control) for 14 days. Body weight (BW), waist circumference (WC), hormones, and pro-inflammatory markers were evaluated. To investigate molecular mechanisms, Gln or Ala was given to Wistar rats on a high-fat diet (HFD), and metabolic parameters, euglycemic hyperinsulinemic clamp with tracers, and Western blot were done. Gln reduced WC and serum lipopolysaccharide (LPS) in overweight volunteers. In the obese group, Gln diminished WC and serum insulin. There was a positive correlation between the reduction on WC and LPS. In rats on HFD, Gln reduced adiposity, improved insulin action and signaling, and reversed both defects in glucose metabolism in the liver and muscle. Gln supplementation increased muscle glucose uptake and reversed the increased hepatic glucose production, in parallel with a reduced glucose uptake in adipose tissue. This insulin resistance in AT was accompanied by enhanced IRS1 O-linked-glycosamine association in this tissue, but not in the liver and muscle. These data suggest that Gln supplementation leads to insulin resistance specifically in adipose tissue via the hexosamine pathway and reduces adipose mass, which is associated with improvement in the systemic insulin action. Thus, further investigation with Gln supplementation should be performed for longer periods in humans before prescribing as a beneficial therapeutic approach for individuals who are overweight and obese
