Qualitative Phase

In contemporary South Africa, partnerships between service providers in government, non-governmental organisations, the private sector and community based organisations have been identified as a means to strengthen communities and the sustainability of social services. However, the unequal power relations that exists between and within these organisations often leads to fragmentation, duplication, and lack of coordination of social services. Using Fowler’s (1998) conceptualisation of authentic partnerships, this qualitative phase of a larger study explored the challenges of building authentic partnerships in Bhambayi, a predominantly informal settlement in KwaZulu-Natal, South Africa. Individual interviews and a focus group held with nine service providers revealed that intraorganisational challenges, cross-boundary and inter-organisational relations as well as political influences were obstacles to the development of authentic partnerships. The article suggests that open communication, clarity of roles and mutual trust between service providers is vital.

Critical Separation

AbstractApproximately one billion people across the globe are living in informal settlements with a large potential fire risk. Due to the high dwelling density, a single informal settlement dwelling fire may result in a very serious fire disaster leaving thousands of people homeless. In this work, a simple physics-based theoretical model was employed to assess the critical fire separation distance between dwellings. The heat flux and ejected flame length were obtained from a full-scale dwelling tests with ISO 9705 dimension (3.6 m × 2.4 m × 2.4 m) to estimate the radiation decay coefficient of the radiation heat flux away from the open door. The ignition potential of combustible materials in adjacent dwellings are analyzed based on the critical heat flux from cone calorimeter tests. To verify the critical distance in real informal settlement fire, a parallel method using aerial photography within geographic information systems (GIS), was employed to determine the critical separation distances in four real informal settlement fires of 2014–2015 in Masiphumelele, Cape Town, South Africa. The fire-spread distances were obtained as well through the real fires. The probabilistic analysis was conducted by Weibull distribution and logistic regression, and the corresponding separation distances were given with different fire spread probabilities. From the experiments with the assumption of no interventions and open doors and windows, it was established that the heat flux would decay from around 36 kW/m2 within a distance of 1.0 m to a value smaller than 5 kW/m2 at a distance of 4.0 m. Both experiments and GIS results agree well and suggest the ignition probabilities at distances of 1.0 m, 2.0 m and 3.0 m are 97%, 52% and 5% respectively. While wind is not explicitly considered in the work, it is implicit within the GIS analyses of fire spread risk, therefore, it is reasonable to say that there is a relatively low fire spread risk at distances greater than 3 m. The distance of 1.0 m in GIS is verified to well and conservatively predict the fire spread risk in the informal settlements.

Fit For Purpose

This paper aims to analyze the financial and operational approach to land regularization and financing used in Brazil by an innovative private social enterprise in order to demonstrate that the approach widens the concept fit-for-purpose land regularization to include fit-for-purpose land financing, with relevance for wider efforts in informal settlement regularization and upgrading. In this approach, the enterprise acts as a coordinator and broker to organize the residents of informal settlements to regularize their settlements by negotiating buyouts of the underlying private owners at discounted values, handling titling and registration of the occupants, and coordinating with municipal governments to provide infrastructure. The analysis of parcel-level repayment and price data provides evidence of the sustainability of the business model and increase of property values of the regularized parcels. The results presented from the enterprise’s own repayment data demonstrate that under (non-pandemic) historical conditions residents are largely able to pay an affordable monthly payment over 7–10 years to the enterprise for the service to purchase the plots and maintain the enterprise. In operation since 2001, the enterprise has regularized over 20,000 parcels in more than 30 settlements, primarily in the cities of Sao Paolo and Curitiba in Brazil. The approach suggests that it could be widely replicable and add to the set of options for regularizing informal settlements, especially when purchase of private land is required.

This paper reports on the indoor and outdoor air quality in informal urban and rural settlements in Kenya. The study is motivated by the need to improve consciousness and to understand the harmful health effects of air quality to vulnerable people, especially in poor communities. Ng’ando urban informal settlement and Leshau Pondo rural village in Kenya are selected as representative poor neighborhoods where unclean energy sources are used indoor for cooking, lighting and heating. Filter based sampling for gravimetrical, elemental composition and black carbon (BC) analysis of particulate matter with an aerodynamic diameter less than 2.5 µm (PM2.5) is performed. findings from Ng’ando and Leshau Pondo showed levels exceeding the limit suggested by the world health organization (WHO), with rare exceptions. Significantly higher levels of PM2.5 and black carbon are observed in indoors than outdoor samples, with a differences in the orders of magnitudes and up to 1000 µg/m3 for PM2.5 in rural settlements. The elemental composition reveals the presence of potentially toxic elements, in addition to characterization, emission sources were also identified. Levels of Pb exceeding the WHO limit are found in the majority of samples collected in the urban locations near major roads with heavy traffic. Our results demonstrate that most of the households live in deplorable air quality conditions for more than 12 h a day and women and children are more affected. Air quality condition is much worse in rural settlements where wood and kerosene are the only available fuels for their energy needs.
