Enumeration as a Grassroot Tool Towards Securing Tenure in Slums: Insights from Kisumu, Kenya

Community-based slum enumeration was carried out in Kisumu from 2005 to 2008 as part of a city-wide slum-upgrading initiative. This paper analyses this enumeration exercise particularly in relation to land management and tenure security. The paper draws on a peer evaluation that included interviews with slumupgrading stakeholders as well as community-based focus group discussions, mainly with enumerators. The paper finds that, for a grassroots enumeration exercise to be successful, grassroots trust must be sustained for ongoing verification and updating of the enumeration data and the enumeration must link up effectively with the planning authorities. Broader preconditions are the coordination of the slumupgrading initiative, and beyond this, of wider and often competing city initiatives. Key findings towards securing tenure include the importance of various forms of mobilisation that accompany enumeration and of the informal and formal knowledge generation that results from the enumeration process

Housing and health in an informal settlement upgrade in Cape Town, South Africa

Taking a socio-ecological perspective the World Health Organisation recognizes that housing comprises four interrelated dimensions—the physical structure of the house, the home, the neighbourhood infrastructure and the community. Housing related health vulnerability arises when residents are exposed to poor conditions in any one of these dimensions and augmented when two or more co-exists. Regardless the relationship between housing and health in the global south remains largely under explored; in particular there has been little focus on health outcomes resulting from upgrading of informal settlements. Applying this framework we report from an in situ upgrading of the informal settlement of Imizamo Yethu in Cape Town, South Africa. Data gathered from surveys are used to determine whether differences in each of these dimensions exist between housing type; both formal upgrades and shacks. Results show that whilst no significant differences exist in self-reported physical health, residents of formal housing are less likely to report mental health issues, have a stronger sense of belonging and report greater satisfaction with both neighbourhood and home than shack residents. However, these contested spaces are not easily interpreted and community tension, exclusion and disadvantage highlight the complex interactions between each of the interrelated dimensions and policies regarding housing intervention. The paper highlights the complex relationship between housing and health that is often lost in simplistic measures of housing when outcomes related to the indoor environment alone are considered

Aerobic intestinal flora of wild-caught African dwarf crocodiles Osteolaemus tetraspis

Intestinal contents were collected from wild-caught African dwarf crocodiles (Osteolaemus tetraspis) in 1993 and 1995 which were slaughtered at urban markets in the Congo Republic. The samples were kept frozen and brought back to Onderstepoort for aerobic culture. Out of 29 specimens, 33 species of bacteria and 20 species of fungi were isolated. The bacteria included three isolates of Salmonella and eight isolates of Escherichia coli, most of the latter being rough strains. The flora of individual specimens contained 1-5 bacterial and 0-5 fungal species. Neither Aeromonas hydrophila nor Edwardsiella tarda were isolated from any of the samples.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Sustainable Urban Systems: Co-design and Framing for Transformation

Rapid urbanisation generates risks and opportunities for sustainable development. Urban policy and decision makers are challenged by the complexity of cities as social–ecological–technical systems. Consequently there is an increasing need for collaborative knowledge development that supports a whole-of-system view, and transformational change at multiple scales. Such holistic urban approaches are rare in practice. A co-design process involving researchers, practitioners and other stakeholders, has progressed such an approach in the Australian context, aiming to also contribute to international knowledge development and sharing. This process has generated three outputs: (1) a shared framework to support more systematic knowledge development and use, (2) identification of barriers that create a gap between stated urban goals and actual practice, and (3) identification of strategic focal areas to address this gap. Developing integrated strategies at broader urban scales is seen as the most pressing need. The knowledge framework adopts a systems perspective that incorporates the many urban trade-offs and synergies revealed by a systems view. Broader implications are drawn for policy and decision makers, for researchers and for a shared forward agenda

Broiler pulmonary hypertension syndrome. II. The direct measurement of right ventricular and pulmonary artery pressures in the closed chest domestic fowl

A technique for the catheterisation of the right ventricle and pulmonary artery of the domestic fowl is described. Mean peak systolic, minimum diastolic and mean pressures measured in the right ventricle and pulmonary artery of a group of clinically normal broilers housed at a medium altitude of 1 300 m were 24,3; 8,1; 17,8; 25,0; 22,1 and 22,3 mm Hg respectively. The pulmonary artery pressures are different from those reported elsewhere using the open chest technique. These differences are possibly due to both the effect of opening the thoracic cavity and the hypoxic pressor effect at this altitude.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Furunculosis in rainbow trout (Salmo gairdneri) raised in sea water

Ulcerative skin lesions were encountered in rainbow trout raised in sea water by a commercial concern in the Western Cape, South Africa. Grossly, the lesions resembled furunculosis but, histopathologically, they differed from typical furunculosis in that bacterial colonies were rarely found in the organs, and also the kidneys and spleens were minimally involved. The causative organism was identified as an achromogenic Aeromonas salmonicida that shared characteristics with all 3 subspecies, salmonicida, masoucida and achromogenes. This is the first report of an outbreak of this disease in South Africa.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Proximal Design in South African Informal Settlements: Users as Designers and the Construction of the Built Environment and its Fire Risks

In many countries, deaths and injuries due to fire in urban areas have been reduced by more equitable infrastructure, more affordable and accessible formal housing, and the provision of state services, including urban planning, professional fire-fighting services, and building regulations (Rush et al 2020). Such developments have proved more challenging in low-and-middle-income-countries, where 95% of the world’s fire deaths and morbidity remain (WHO 2004). Fire risk is particularly stark in informal settlements, which currently house one billion people across the globe. In Africa alone, this number is expected to grow to 1.2 billion by 2050 (UN-Habitat 2016). The definition of an informal settlement varies around the globe, but in the case of South Africa it is often referred to as an ‘unplanned settlement on land which has not been surveyed or proclaimed as residential, consisting mainly of informal dwellings (shacks)’ (SACB 2012)
