Effects of cash transfers on Children's health and social protection in Sub-Saharan Africa: differences in outcomes based on orphan status and household assets

BACKGROUND: Unconditional and conditional cash transfer programmes (UCT and CCT) show potential to improve the well-being of orphans and other children made vulnerable by HIV/AIDS (OVC). We address the gap in current understanding about the extent to which household-based cash transfers differentially impact individual children’s outcomes, according to risk or protective factors such as orphan status and household assets. METHODS: Data were obtained from a cluster-randomised controlled trial in eastern Zimbabwe, with random assignment to three study arms – UCT, CCT or control. The sample included 5,331 children ages 6-17 from 1,697 households. Generalized linear mixed models were specified to predict OVC health vulnerability (child chronic illness and disability) and social protection (birth registration and 90% school attendance). Models included child-level risk factors (age, orphan status); household risk factors (adults with chronic illnesses and disabilities, greater household size); and household protective factors (including asset-holding). Interactions were systematically tested. RESULTS: Orphan status was associated with decreased likelihood for birth registration, and paternal orphans and children for whom both parents’ survival status was unknown were less likely to attend school. In the UCT arm, paternal orphans fared better in likelihood of birth registration compared with non-paternal orphans. Effects of study arms on outcomes were not moderated by any other risk or protective factors. High household asset-holding was associated with decreased likelihood of child’s chronic illness and increased birth registration and school attendance, but household assets did not moderate the effects of cash transfers on risk or protective factors. CONCLUSION: Orphaned children are at higher risk for poor social protection outcomes even when cared for in family-based settings. UCT and CCT each produced direct effects on children’s social protection which are not moderated by other child- and household-level risk factors, but orphans are less likely to attend school or obtain birth registration. The effects of UCT and CCT are not moderated by asset-holding, but greater household assets predict greater social protection outcomes. Intervention efforts need to focus on ameliorating the additional risk burden carried by orphaned children. These efforts might include caregiver education, and additional incentives based on efforts made specifically for orphaned children

Household-based cash transfer targeting strategies in Zimbabwe: are we reaching the most vulnerable children?

Census data, collected in July 2009, from 27,672 children were used to compare the effectiveness, coverage and efficacy of three household-based methods for targeting cash transfers to vulnerable children in eastern Zimbabwe: targeting the poorest households using a wealth index; targeting HIVaffected households using socio-demographic information (households caring for orphans, chronicallyill or disabled members; child-headed households); and targeting labour-constrained households using dependency ratios. All three methods failed to identify large numbers of children with poor social and educational outcomes. The wealth index approach was the most efficient at reaching children with poor outcomes whilst socio-demographic targeting reached more vulnerable children but was less efficient.publishedVersio

Effects of unconditional and conditional cash transfers on child health and development in Zimbabwe: a cluster-randomised trial

SummaryBackgroundCash-transfer programmes can improve the wellbeing of vulnerable children, but few studies have rigorously assessed their effectiveness in sub-Saharan Africa. We investigated the effects of unconditional cash transfers (UCTs) and conditional cash transfers (CCTs) on birth registration, vaccination uptake, and school attendance in children in Zimbabwe.MethodsWe did a matched, cluster-randomised controlled trial in ten sites in Manicaland, Zimbabwe. We divided each study site into three clusters. After a baseline survey between July, and September, 2009, clusters in each site were randomly assigned to UCT, CCT, or control, by drawing of lots from a hat. Eligible households contained children younger than 18 years and satisfied at least one other criteria: head of household was younger than 18 years; household cared for at least one orphan younger than 18 years, a disabled person, or an individual who was chronically ill; or household was in poorest wealth quintile. Between January, 2010, and January, 2011, households in UCT clusters collected payments every 2 months. Households in CCT clusters could receive the same amount but were monitored for compliance with several conditions related to child wellbeing. Eligible households in all clusters, including control clusters, had access to parenting skills classes and received maize seed and fertiliser in December, 2009, and August, 2010. Households and individuals delivering the intervention were not masked, but data analysts were. The primary endpoints were proportion of children younger than 5 years with a birth certificate, proportion younger than 5 years with up-to-date vaccinations, and proportion aged 6–12 years attending school at least 80% of the time. This trial is registered with ClinicalTrials.gov, number NCT00966849.Findings1199 eligible households were allocated to the control group, 1525 to the UCT group, and 1319 to the CCT group. Compared with control clusters, the proportion of children aged 0–4 years with birth certificates had increased by 1·5% (95% CI −7·1 to 10·1) in the UCT group and by 16·4% (7·8–25·0) in the CCT group by the end of the intervention period. The proportions of children aged 0–4 years with complete vaccination records was 3·1% (−3·8 to 9·9) greater in the UCT group and 1·8% (−5·0 to 8·7) greater in the CCT group than in the control group. The proportions of children aged 6–12 years who attended school at least 80% of the time was 7·2% (0·8–13·7) higher in the UCT group and 7·6% (1·2–14·1) in the CCT group than in the control group.InterpretationOur results support strategies to integrate cash transfers into social welfare programming in sub-Saharan Africa, but further evidence is needed for the comparative effectiveness of UCT and CCT programmes in this region.FundingWellcome Trust, the World Bank through the Partnership for Child Development, and the Programme of Support for the Zimbabwe National Action Plan for Orphans and Vulnerable Children

NW Borneo reservoir characterisation based on sedimentological evaluation of turbidite facies

Borneo was positioned in an exceedingly dynamic tectonic area throughout the Tertiary at the edge of an Early Cretaceous continental fragment and is surrounded by the Sunda Shelf, South China Sea, Sulu Sea, Celebes Sea, the narrow Makassar Strait and the Java Sea. Throughout this period of time, the Northwest Borneo basin and other adjacent basins (sedimentary and marginal) were formed and deformed as a result of the subduction and extension of the surrounding plates. The Northwest Borneo basin is distinguished by a steep slope from shelf to basin floor and shows high flow rates of turbidite sediment. The study areas include the Northwest Borneo Basin (offshore; 10.6 to 8.2 Ma) and the on-shore area covered by the Crocker Formation (Eocene to Early Miocene) on northwest Borneo and Gaya Island near Kota Kinabalu, East Malaysia. The Crocker Formation covers an area from 115o 58’E to 116o 09’E longitude and 05o 46’N to 06o 01’N latitude. All the study areas display characteristics of sediment deposited during lowstand systems tract (LST) and illustrate type II turbidite depositional systems consisting of proximal and distal turbidite deposits. The turbidite sediments accumulated in small lobes and are usually found deposited in the distal parts of the distributary channels. Ta-Tb-Tc-Td-Te Bouma sequences are present in all study areas but, commonly the base, middle or top of the sequences are absent. Other facies identified are massive sandstone, wispy sandstone and chaotic interbedded sandstone and mudstone sequences (Sm, Sw and Sa facies)

Involving communities in the targeting of cash transfer programs for vulnerable children: opportunities and challenges

We used baseline data, collected in July–September 2009, from a randomized controlled trial of a cash transfer program for vulnerable children in eastern Zimbabwe to investigate the effectiveness, coverage, and efficiency of census- and community-based targeting methods for reaching vulnerable children. Focus group discussions and in-depth interviews with beneficiaries and other stakeholders were used to explore community perspectives on targeting. Community members reported that their participation improved ownership and reduced conflict and jealousy. However, all the methods failed to target a large proportion of vulnerable children and there was poor agreement between the community- and census-based methods

Household-based cash transfer targeting strategies in Zimbabwe: are we reaching the most vulnerable children?

Asset ownership among households caring for orphans and vulnerable children in rural Zimbabwe: The influence of ownership on children's health and social vulnerabilities

The high prevalence of human immunodeficiency virus/acquired immune deficiency syndrome in sub-Saharan Africa has resulted in a dramatic increase in orphans and vulnerable children (OVC) over the past decade. These children typically rely on extended family networks for support, but the magnitude of the crisis has resulted in traditional familial networks becoming overwhelmed and more economically and socially vulnerable. Previous research consistently demonstrates the positive influence of household asset ownership on children's well-being. Using data from impoverished households caring for OVC in rural Manicaland Province, Zimbabwe, this study explores the influence of household asset ownership on OVC health vulnerability (HV) and social vulnerability (SV). Findings indicate that asset ownership is associated with significantly lower SV, in terms of school attendance and birth registration. Yet, assets do not emerge as a direct influence of OVC HV as measured by disease and chronic illness, although having a chronically ill adult in the household increases HV. These findings suggest that asset ownership, specifically a combination of fixed and movable assets, may offset the influence of other risk factors for children's SV
