    The basic question about ā€˜how many poor people are there in the world?ā€™ generally assumes that poverty is measured according to international poverty lines (IPLs). Yet, an equally relevant question could be ā€˜how many poor people are there in the world, based on how poverty is defined where those people live?ā€™ In short, rather than a comparison based on monetary values, the latter question is germane to estimates based on a concept ā€“ ā€˜povertyā€™ ā€“ as defined by countriesā€™ specific circumstances and institutions. Estimates of poverty by national poverty lines (NPLs) and international poverty lines (IPLs) may vary in terms of technical grounds. But how similar are they? How different is poverty captured by comparable (in PPP monetary value) cross-country measures as embodied by the IPL compared to that viewed in NPLs? This paper offers a new perspective on global poverty. It does so by estimating the distribution of poverty across countries, regions and income categories based on national poverty lines (NPLs). Even though comparing NPLs across countries means comparing poverty lines of different monetary value, we argue that exploring ā€œpovertyā€ as a nationally defined concept by countries at different stages of development unveils important and often unnoticed findings. By addressing the question of poverty as defined where those poor people live, this paper seeks to offer a new perspective on global poverty and at the same time extend thinking on the ā€˜middle-income countries poverty paradoxā€™ ā€“ meaning that most of the worldā€™s poor do not live in the worldā€™s poorest countries Using data from 160 countries covering nearly 92 per cent of world population, we estimate that globally 1.5 billion people live in poverty as defined within their own countries (by NPLs), a billion of which are in middle-income countries (MICs) and - surprisingly perhaps - one in ten of worldā€™s poor live in high-income countries (HICs). Our analysis shows that NPL and IPL-based estimates lead to similar poverty estimates only in a limited number of cases. In particular, we conclude that (i) there is a considerable difference between regional and national poverty estimates based on IPLs and NPLs ā€“ that is, differences for a same country could be as high as 55 percentage points in poverty rates, or about 45 million in the number of poor people; (ii) NPLs may be particularly important for analysis of poverty in MICs: indeed, their NPLs donā€™t feed into the construction of IPLs. Hence, poverty at national level may not be adequately captured by IPLs themselves; (iii) NPLs are not substitutes for IPLs, but instead enrich and complement international analyses. Yet, there could be trade-offs between the two, especially in terms of different development actors tracking different poverty estimates. Our findings also have implications for debates about global poverty targets and international assistance. Keywords: poverty; inequality; aid; Middle-Income; Low-Income Countrie

    The analytical framework of water and armed conflict: a focus on the 2006 Summer War between Israel and Lebanon

    Get PDF
    This paper develops an analytical framework to investigate the relationship between water and armed conflict, and applies it to the ā€˜Summer Warā€™ of 2006 between Israel and Lebanon (Hezbollah). The framework broadens and deepens existing classifications by assessing the impact of acts of war as indiscriminate or targeted, and evaluating them in terms of international norms and law, in particular International Humanitarian Law (IHL). In the case at hand, the relationship is characterised by extensive damage in Lebanon to drinking water infrastructure and resources. This is seen as a clear violation of the letter and the spirit of IHL, while the partial destruction of more than 50 public water towers compromises water rights and national development goals. The absence of pre-war environmental baselines makes it difficult to gauge the impact on water resources, suggesting a role for those with first-hand knowledge of the hostilities to develop a more effective response before, during, and after armed conflict

    Intercomparison of global river discharge simulations focusing on dam operation --- Part II: Multiple models analysis in two case-study river basins, Missouri-Mississippi and Green-Colorado

    Get PDF
    We performed a twofold intercomparison of river discharge regulated by dams under multiple meteorological forcings among multiple global hydrological models for a historical period by simulation. Paper II provides an intercomparison of river discharge simulated by five hydrological models under four meteorological forcings. This is the first global multimodel intercomparison study on dam-regulated river flow. Although the simulations were conducted globally, the Missouri-Mississippi and Green-Colorado Rivers were chosen as case-study sites in this study. The hydrological models incorporate generic schemes of dam operation, not specific to a certain dam. We examined river discharge on a longitudinal section of river channels to investigate the effects of dams on simulated discharge, especially at the seasonal time scale. We found that the magnitude of dam regulation differed considerably among the hydrological models. The difference was attributable not only to dam operation schemes but also to the magnitude of simulated river discharge flowing into dams. That is, although a similar algorithm of dam operation schemes was incorporated in different hydrological models, the magnitude of dam regulation substantially differed among the models. Intermodel discrepancies tended to decrease toward the lower reaches of these river basins, which means model dependence is less significant toward lower reaches. These case-study results imply that, intermodel comparisons of river discharge should be made at different locations along the riverā€™s course to critically examine the performance of hydrological models because the performance can vary with the locations

    Social capital theory: a cross-cutting analytic for teacher/therapist work in integrating children's services?

    Get PDF
    Reviewing relevant policy, this article argues that the current 'integration interlude' is concerned with reformation of work relations to create new forms of 'social capital'. The conceptual framework of social capital has been used by government policy-makers and academic researchers to examine different types, configurations and qualities of relationships, including professional relations, and how these may function as resources. Focusing on the co-work of teachers and speech and language therapists, this analysis introduces social capital as a means of understanding the impact of integrating children's services on professional practitioner groups and across agencies. Social capital theory is compared to alternative theoretical perspectives such as systems and discourse theories and explored as an analytic offering a multi-level typology and conceptual framework for understanding the effects of policy and governance on interprofessional working and relationships. A previous application of social capital theory in a literature review is introduced and analysed, and instances of the additionality provided by a social capital analysis is offered. The article concludes that amongst the effects of current policy to re-design children's services are the reconstruction of professionals' knowledge/s and practices, so it is essential that such policy processes that have complex and far-reaching effects are transparent and coherent. It is also important that new social capital relations in children's services are produced by groups representative of all involved, importantly including those practitioner groups charged in policy to work differently together in future integrated services

    Cross-Sector Review of Drivers and Available 3Rs Approaches for Acute Systemic Toxicity Testing

    Get PDF
    Acute systemic toxicity studies are carried out in many sectors in which synthetic chemicals are manufactured or used and are among the most criticized of all toxicology tests on both scientific and ethical grounds. A review of the drivers for acute toxicity testing within the pharmaceutical industry led to a paradigm shift whereby in vivo acute toxicity data are no longer routinely required in advance of human clinical trials. Based on this experience, the following review was undertaken to identify (1) regulatory and scientific drivers for acute toxicity testing in other industrial sectors, (2) activities aimed at replacing, reducing, or refining the use of animals, and (3) recommendations for future work in this area

    Agreement between physicians and non-physician clinicians in starting antiretroviral therapy in rural Uganda

    <p>Abstract</p> <p>Background</p> <p>The scarcity of physicians in sub-Saharan Africa ā€“ particularly in rural clinics staffed only by non-physician health workers ā€“ is constraining access to HIV treatment, as only they are legally allowed to start antiretroviral therapy in the HIV-positive patient. Here we present a pilot study from Uganda assessing agreement between non-physician clinicians (nurses and clinical officers) and physicians in their decisions as to whether to start therapy.</p> <p>Methods</p> <p>We conducted the study at 12 government antiretroviral therapy sites in three regions of Uganda, all of which had staff trained in delivery of antiretroviral therapy using the WHO Integrated Management of Adult and Adolescent Illness guidelines for chronic HIV care. We collected seven key variables to measure patient assessment and the decision as to whether to start antiretroviral therapy, the primary variable of interest being the Final Antiretroviral Therapy Recommendation. Patients saw either a clinical officer or nurse first, and then were screened identically by a blinded physician during the same clinic visit. We measured inter-rater agreement between the decisions of the non-physician health workers and physicians in the antiretroviral therapy assessment variables using simple and weighted Kappa analysis.</p> <p>Results</p> <p>Two hundred fifty-four patients were seen by a nurse and physician, while 267 were seen by a clinical officer and physician. The majority (> 50%) in each arm of the study were in World Health Organization Clinical Stages I and II and therefore not currently eligible for antiretroviral therapy according to national antiretroviral therapy guidelines. Nurses and clinical officers both showed moderate to almost perfect agreement with physicians in their Final Antiretroviral Therapy Recommendation (unweighted Īŗ = 0.59 and Īŗ = 0.91, respectively). Agreement was also substantial for nurses versus physicians for assigning World Health Organization Clinical Stage (weighted Īŗ = 0.65), but moderate for clinical officers versus physicians (Īŗ = 0.44).</p> <p>Conclusion</p> <p>Both nurses and clinical officers demonstrated strong agreement with physicians in deciding whether to initiate antiretroviral therapy in the HIV patient. This could lead to immediate benefits with respect to antiretroviral therapy scale-up and decentralization to rural areas in Uganda, as non-physician clinicians ā€“ particularly clinical officers ā€“ demonstrated the capacity to make correct clinical decisions to start antiretroviral therapy. These preliminary data warrant more detailed and multicountry investigation into decision-making of non-physician clinicians in the management of HIV disease with antiretroviral therapy, and should lead policy-makers to more carefully explore task-shifting as a shorter-term response to addressing the human resource crisis in HIV care and treatment.</p
