Spatial analyses of threats to ecosystem service hotspots in Greater Durban, South Africa.

ABSTRACT: Background:Population growth at all scales and rapid rates of urbanization, particularly in the global South, are placing increasing pressure on ecosystems and their ability to provide services essential for human well-being. The spatial consideration of threats to ecosystem services related to changes in land use is necessary in order to avoid undue impacts on society due to the loss or reduced supply of ecosystem services. This study assesses the potential threats of land use change from strategic and local development proposals to ecosystem services in the city of Durban. Methods:We analysed the spatial relationship between five categories of ecosystem service hotspots (carbon storage, water yield, sediment retention, nutrient retention and flood attenuation) and urban land use change related to selected strategic planning proposals, development proposals and sand-mining applications in Durban, South Africa (eThekwini Municipality) with a view to determining the consequences for progress towards a more sustainable development path in the city. We identified the potential levels of threat related to habitat destruction or transformation for the five categories of ecosystem services and a subset of 13 ecosystem service hotspots, using GIS spatial analysis tools. Results:The results show that on average, should Durban's strategic development plans be realised, approximately 42% loss of ecosystem service hotspots is expected in the two municipal town-planning regions assessed. With respect to development applications between 2009 and 2012, approximately 36% of all environmental impact assessments and 84% of sand mining applications occurred within ecosystem service hotspots within Durban. Discussion:The findings highlight the tension between short-term development pressures and longer-term sustainability goals and confirm that current planning and development proposals pose a threat to ecosystems and their ability to deliver services that support human well-being in Durban. We suggest practical solutions to include ecosystem services into local government decision-making.

Project description:BackgroundRefugees are generally considered a vulnerable population, with refugee children (newborn and young children) being particularly so. Access to healthcare for this population remains a challenge. The main purpose of this study was to explore refugee caregivers' perceptions of their children's access to quality health service delivery to their young children in Durban, South Africa.MethodsThis study used an explanatory mixed methods design, purposively sampling 120 and 10 participants for the quantitative and qualitative phases, respectively. Participants were administered a self-developed questionnaire that assessed demographic information of participants, socioeconomic status and living standard, medical history of children, satisfaction and experiences with healthcare services and refugees' networks and social support. A semi-structured interview schedule was developed to elicit in-depth and more detailed information from the participants on the quantitative areas that were investigated. Frequencies were calculated and a χ2 test was used to explore the factors associated with refugees' satisfaction of the healthcare provided and thematic analysis was used to analyse the qualitative data.ResultsThe majority (89%) of caregivers were women, with over 70% of them aged between 30 and 35 years. Over 74% of caregivers visited public clinics for their children's healthcare needs. The majority of caregivers (95%) were not satisfied with healthcare services delivery to their children due to the long waiting hours and the negative attitudes and discriminatory behaviours of healthcare workers, particularly in public healthcare facilities.ConclusionThese findings underscore the need to address health professionals' attitudes when providing healthcare for refugees. Attitudinal change may improve the relationship between service providers and caregivers of refugee children in South Africa, which may improve the health-related outcomes in refugee children.

Project description:ObjectiveInfections are common in systemic lupus erythematosus (SLE), with tuberculosis (TB) being important in an endemic environment. We studied the prevalence and spectrum of TB in SLE in Durban, South Africa.MethodsA medical records review of SLE patients seen over 13-year period, and the demographic data, clinical manifestations, laboratory findings, treatment and outcome were noted.ResultsThere were 512 SLE patients and 72 (14.1%) had TB. Thirty (41.7%) had pulmonary TB (PTB) and 42 (58.3%) had extra-pulmonary TB (EPTB). The prevalence of TB among the different ethnic groups was 36/282 (12.8%) for Indian people, 29/184 (15.8%) Black African people, 7/26 (26.9%) admixed African people and none among the 18 White people. Comparison of the 72 SLE-TB patients with 72 SLE controls showed no difference in gender, age at SLE diagnosis and disease duration. The SLE-TB patients had a significant increase in the clinical and laboratory features of disease activity (arthritis, mucocutaneous lesions, renal involvement, vasculitis, low complement, raised ds-DNA antibodies), and cumulative prednisone use over the preceding 3 months.Compared to PTB, the EPTB patients were significantly younger, developed TB earlier after SLE diagnosis, and had higher disease activity. The EPTB patients also had increase in features of disease activity (renal, thrombocytopenia, ds-DNA antibodies), and increase in ever use of intravenous methylprednisolone (IV-MP) and mycophenolate mofetil (MMF). On multivariate analysis, the independent risk factors for EPTB were ever use of MMF (p = 0.003) and IV-MP (p = 0.027). Analysis of the cumulative SLE criteria showed renal involvement was an independent risk factor for EPTB. The outcome was similar in both groups.ConclusionWe show an increased prevalence of TB (14.1%) and EPTB (58.3%) in SLE in an endemic area and confirm that features of disease activity and use of immunosuppressive therapy are the major risk factors. Renal involvement (as a cumulative criterion) is an independent risk factor for EPTB.
