    ICDS in India: Policy, Design and Delivery Issues

    Get PDF
    India's excellent economic growth in the last two decades has made little impact on the nutrition levels of its children. Its main intervention, the Integrated Child Development Services (ICDS) programme, has not yet succeeded in reducing child malnutrition. The programme is reaching less than one?third of all children. ICDS also faces substantial operational challenges, such as lack of monitoring. The article discusses the flaws in the design of ICDS, and suggests practical measures to improve its implementation. It argues that the basic nature of the ICDS scheme should be changed from centre?based to outreach?based, with a focus on children under two years old. The emphasis should be on the difficult tasks of changing child?rearing practices, and the control and treatment of infectious diseases. The article argues against provision of packaged food, as this is unpopular with young children and has led to corruption

    Post-Mortem Echocardiography as a Guide to Cardiac Autopsy—A Worthwhile Concept?

    Get PDF
    Sudden and unexpected death in the young is a common and worldwide problem. Sudden, unexpected death in infancy (SUDI), clinically unexpected death in an infant between one week and one year of age, affects around 1 in 1000 infants. Autopsy will reveal a specific cause of death in only one third of cases. This has led to various ancillary examinations in an effort to increase the diagnostic yield of the autopsy

    Agriculture, nutrition and education: On the status and determinants of primary schooling in rural Mali before the crises of 2012

    This cross-sectional study examines the status and the determinants of primary education in food insecure areas of Mali. Net and gross enrolment ratios in primary school were between 0.3 and 0.4 for both girls and boys and well below national levels, highlighting a critical gap in terms of access to primary education. Schooling was found to respond to a broad range of determinants, including child's age and nutrition status, as well as on household consumption, on farm labour, teacher availability, and village level remoteness. Interestingly, no significant gender differences were found in terms of primary education. School meals were found to be associated with increased enrolment, attendance and attainment. The scale of the problem in Mali strongly suggests the need for investments in education and social protection to be prioritised and funded as part of national education policy and development strategies

    Green revolution in Sub-Saharan Africa: Implications of imposed innovation for the wellbeing of rural smallholders

    Green Revolution policies are again being pursued to drive agricultural growth and reduce poverty in Sub-Saharan Africa. However conditions have changed since the well-documented successes of the 1960s and 1970s benefited smallholders in southern Asia and beyond. We argue that under contemporary constraints the mechanisms for achieving improvements in the lives of smallholder farmers through such policies are unclear and that both policy rationale and means of governing agricultural innovation are crucial for pro-poor impacts. To critically analyze Rwanda’s Green Revolution policies and impacts from a local perspective, a mixed methods, multidimensional wellbeing approach is applied in rural areas in mountainous western Rwanda. Here Malthusian policy framing has been used to justify imposed rather than ‘‘induced innovation”. The policies involve a substantial transformation for rural farmers from a traditional polyculture system supporting subsistence and local trade to the adoption of modern seed varieties, inputs, and credit in order to specialize in marketable crops and achieve increased production and income. Although policies have been deemed successful in raising yields and conventionally measured poverty rates have fallen over the same period, such trends were found to be quite incongruous with local experiences. Disaggregated results reveal that only a relatively wealthy minority were able to adhere to the enforced modernization and policies appear to be exacerbating landlessness and inequality for poorer rural inhabitants. Negative impacts were evident for the majority of households as subsistence practices were disrupted, poverty exacerbated, local systems of knowledge, trade, and labor were impaired, and land tenure security and autonomy were curtailed. In order to mitigate the effects we recommend that inventive pro-poor forms of tenure and cooperation (none of which preclude improvements to input availability, market linkages, and infrastructure) may provide positive outcomes for rural people, and importantly in Rwanda, for those who have become landless in recent years. We conclude that policies promoting a Green Revolution in Sub-Saharan Africa should not all be considered to be pro-poor or even to be of a similar type, but rather should be the subject of rigorous impact assessment. Such assessment should be based not only on consistent, objective indicators but pay attention to localized impacts on land tenure, agricultural practices, and the wellbeing of socially differentiated people

    Increased yield stability of field-grown winter barley (Hordeum vulgare L.) varietal mixtures through ecological processes

    Crop variety mixtures have the potential to increase yield stability in highly variable and unpredictable environments, yet knowledge of the specific mechanisms underlying enhanced yield stability has been limited. Ecological processes in genetically diverse crops were investigated by conducting field trials with winter barley varieties (Hordeum vulgare), grown as monocultures or as three-way mixtures in fungicide treated and untreated plots at three sites. Mixtures achieved yields comparable to the best performing monocultures whilst enhancing yield stability despite being subject to multiple predicted and unpredicted abiotic and biotic stresses including brown rust (Puccinia hordei) and lodging. There was compensation through competitive release because the most competitive variety overyielded in mixtures thereby compensating for less competitive varieties. Facilitation was also identified as an important ecological process within mixtures by reducing lodging. This study indicates that crop varietal mixtures have the capacity to stabilise productivity even when environmental conditions and stresses are not predicted in advance. Varietal mixtures provide a means of increasing crop genetic diversity without the need for extensive breeding efforts. They may confer enhanced resilience to environmental stresses and thus be a desirable component of future cropping systems for sustainable arable farming
