ECONOMIC INTEGRATION FOR DEVELOPMENT IN EASTERN AND SOUTHERN AFRICA: ASSESSMENT AND PROSPECTS

Summary Eastern and Southern Africa has a long history of efforts to achieve operational economic integration and a complex set of overlapping institutional frames. The gains from successful cooperation are agreed ? the basic issues turn on how to attain them. In this context the experiences of the two key actors, PTA (Preferential Trade Area) and SADC (Southern African Development Community), offer insights into the strengths and weaknesses of a broad, secretariat?led trade barrier reducing organization and a narrower (geographically), key sector production coordination, country?led one (SADC). The divergences ? as well as history ? have hampered attempts to coordinate or to merge them and their responses to the opportunities and challenges posed by the re?entry of South Africa into Africa. The latter raises rather more complex issues (and ones less threatening ? or promising in some respects ? to its Eastern and Southern African region potential partners) than is sometimes supposed. Resumé efforts pour d'obtenir l'intégration économique et de rendre celle?ci opérationnelle dans le contexte d'une série complexe de cadres institutionnels parfois superposés. Les gains résultant des réussites dans la coopération ne sont pas contestés: les questions fondamentales tournent autour des moyens d'y parvenir. Dans ce contexte l'expérience de deux acteurs principaux (la PTA – Preferential Trade Area ou Zone commerciale privilégiée et la SADC – Southern African Development Community ou Communauté de développement de l'Afrique australe) offrent des aperçus quant aux avantages et désavantages de l'existence d'une organisation de grande envergure et fondée sur secrétariat, consacrée à la réduction des barrières douannières, et d'une autre organisation, cette fois limitée en termes de sa superficie géographique et menée par des pays, qui cherche à coordiner la production dans les secteurs clef: la SADC. Leurs divergences, et l'histoire même, ont servi d'entrave aux efforts de les coordiner ou de les faire fusionner, surtout en ce qui concerne les nouvelles possibilités et le challenge même de la réintégration de l'Afrique du Sud dans la grande Afrique. Cette réintégration soulève des questions un peu plus complexes (et moins menaçantes) et aussi, moins promettrices sous certains jours pour ses éventuels partenaires dans les régions orientales et australes de l'Afrique) qu'on ne le supposerait parfois. Resumen El Africa oriental y el Africa austral tienen un largo historial de esfuerzos para alcanzar la integración económica operacional y un complejo grupo de estructuras institucionales superpuestas. Los beneficios de una cooperación exitosa no están en discusión ? el punto básico es cómo obtenerlos. En este contexto las experiencias de dos actores clave, (la PTA?Preferential Trade Area o Zona de Comercio Privilegiado, y la SADC ? Southern Africa Development Community o Comunidad para el Desarrollo de Africa Austral), ofrecen interesantes revelaciones sobre los puntos fuertes y débiles de una amplia y burocrática barrera comercial que reduce la organización, y la coordinación de la producción en sectores clave de un área geográfica más reducida, de orientación nacional. Las divergenias ? así como la historia ? han estorbado intentos de combinar o coordinar estos dos aspectos y sus respuestas a las oportunidades o desafíos que presenta el reingreso de Sudafrica al Africa. Esto último plantea más asuntos complejos de los que a veces se suponen (y menos amenazantes ? más prometedores en alugunos aspectos) para sus socios comerciales en potencia en Africa oriental y Africa del sur

Inequities and their determinants in coverage of maternal health services in Burkina Faso

Background: Poor and marginalized segments of society often display the worst health status due to limited access to health enhancing interventions. It follows that in order to enhance the health status of entire populations, inequities in access to health care services need to be addressed as an inherent element of any effort targeting Universal Health Coverage. In line with this observation and the need to generate evidence on the equity status quo in sub-Saharan Africa, we assessed the magnitude of the inequities and their determinants in coverage of maternal health services in Burkina Faso. Methods: We assessed coverage for three basic maternal care services (at least four antenatal care visits, facility-based delivery, and at least one postnatal care visit) using data from a cross-sectional household survey including a total of 6655 mostly rural, poor women who had completed a pregnancy in the 24 months prior to the survey date. We assessed equity along the dimensions of household wealth, distance to the health facility, and literacy using both simple comparative measures and concentration indices. We also ran hierarchical random effects regression to confirm the presence or absence of inequities due to household wealth, distance, and literacy, while controlling for potential confounders. Results: Coverage of facility based delivery was high (89%), but suboptimal for at least four antenatal care visits (44%) and one postnatal care visit (53%). We detected inequities along the dimensions of household wealth, literacy and distance. Service coverage was higher among the least poor, those who were literate, and those living closer to a health facility. We detected a significant positive association between household wealth and all outcome variables, and a positive association between literacy and facility-based delivery. We detected a negative association between living farther away from the catchment facility and all outcome variables. Conclusion: Existing inequities in maternal health services in Burkina Faso are likely going to jeopardize the achievement of Universal Health Coverage. It is important that policy makers continue to strengthen and monitor the implementation of strategies that promote proportionate universalism and forge multi-sectoral approach in dealing with social determinants of inequities in maternal health services coverage

NON-PHYSICAL BARRIERS TO TRAFFIC FLOW AND THE PTA PROGRAMME OF ACTION: PROBLEMS AND PROSPECTS

A lot of resources have .been committed to the provision of transport infrastructure in Eastern and Southern Africa. Some of these resources have been borrowed from outside and have to be repaid. Hence the need to maximize their use. However, this is being minimized by non-infrastructural bottlenecks to traffic flow. These range from macro-economic constraints with implications for passenger (bus) transport such as the non-availability or acute shortage of foreign exchange to slow, cumbersome documentation procedures particularly for cross-border traffic. The Preferential Trade Area (PTA) for Eastern and Southern Africa is geared to the reduction and eventual elimination of actual and potential non-physical barriers to traffic flow, for which it has instituted a number of schemes. After introductory remarks on the sub-regional economy, its transport sector and avenues for sub-regional cooperation and the implementation of these schemes is assessed and other non-physical barriers yet to be addressed by the PTA are examined before conclusions are drawn

New strategies for controlling ticks

Ticks and the diseases they transmit are widely distributed throughout the world, particularly in tropical and subtropical countries. Ticks transmit numerous rickettsial, spirochetal, protozoan and viral pathogens to humans, many of which can produce fatal or debilitating infections. The importance of ticks in animal health and production lies in the enormous economic losses they cause by transmitting a wide variety of pathogens and by direct damage to their hosts. In addition, most livestock-parasitizing tick species are also capable of transmitting disease agents to man. In the developing world, the losses from ticks and tick-borne diseases are not merely economic. In many areas, malnourished people are deprived of animal protein and fat needed to increase their resistance to debilitating infectious diseases.

A novel, energy efficient, two stage heap leach process for the extraction and recovery of PGMs

The platinum group metals (PGMs) and associated minerals are particularly refractory to most traditional direct leach processes. However, the remoteness of many new ore deposits, socio-political risks, the scarcity of skilled labor and constraints on the availability of water and electrical power makes it increasingly more difficult to implement the conventional mill-float-smelt-refine process routes to extract and refine PGMs in remote areas. This paper discusses a process to extract PGMs from low grade ore and concentrate using a sequential stage heap leach process entailing heap bioleaching and high temperature cyanide leaching, and evaluates the feasibility of implementing a carbon-in-pulp process to recover the PGMs from the pregnant leach solution. The heap bioleaching extracts the base metals in an acidic sulfate medium using a mixed culture of thermophiles. After heap bioleaching the heap is reclaimed, rinsed, agglomerated and restacked for high temperature cyanide leaching where the cyanide liquor is directly heated via solar energy in panels. Palladium, gold and platinum are recovered during the cyanide leaching stage. The pregnant leach solution was evaluated for potential carbon-in-pulp adsorption and subsequent elution similar to gold processing. The kinetics of adsorption and elution compared well with gold adsorption and elution
