Web-based climate information resources for malaria control in Africa

Malaria remains a major public health threat to more than 600 million Africans and its control is recognized as critical to achieving the Millennium Development Goals. The greatest burden of malaria in Africa occurs in the endemic regions where the disease pathogen is continuously present in the community. These regions are characterized by an environment that is conducive to interactions between the Anopheles mosquito, malaria parasites and human hosts, as well as housing of generally poor quality, which offers little protection from mosquito-human contact. Epidemic malaria tends to occur along the geographical margins of endemic regions, when the equilibrium between the human, parasite and mosquito vector populations is occasionally disturbed and a sharp but temporary increase in disease incidence results. When malaria control measures are inadequate, as is the case in much of sub-Saharan Africa, the disease distribution is closely linked with seasonal patterns of the climate and local environment. In the absence of good epidemiological data on malaria distribution in Africa, climate information has long been used to develop malaria risk maps that illustrate the boundaries of 'climatic suitability for endemic transmission.' The best known of these are produced by the Pan-African-based MARA Collaboration. This paper describes the development of additional malaria suitability maps which have been produced in an online, interactive format to enable temporal information (i.e., seasonality of climate conditions) to be queried and displayed along with spatial information. These maps and the seasonal information that they contain should be useful to the malaria control and health service communities for their planning and operational activities

Climate and health in Africa

This paper describes the work of the International Research Institute for Climate and Society (IRI) and its partners towards the development of climate services for the health sector in Africa; integrating research, operational applications and capacity building alongside policy development and advocacy. It follows the evolution of IRI’s health work from an initial focus on the use of seasonal climate forecasts to a wider agenda serving climate and environmental information needs to a broad range of health-related users. Recognizing that climate information must be relevant to the priority policy and programming needs of national and international health stakeholders, this review highlights an approach that has centered not only on the assessment and creation of evidence, but also on knowledge transfer through engagement with decision-makers. Current opportunities and priorities identified for the routine use of climate and environmental information in health in Africa include: i) understanding mechanisms by which climate impacts on transmission and occurrence of disease; ii) mapping populations at risk both in space and by season; iii) developing early warning systems; iv) understanding the contributions of climate to trends in disease incidence v) improving the evaluation of the impacts of climate-sensitive interventions. While traditional metrics (e.g. peer review publications) have been important in establishing evidence for policy, the IRI’s role as a knowledge broker (in research and professional capacity building, facilitation of communities of practice, and engagement in policy dialogue at local and global scale) has been critical to delivery of its mission

Using climate information for improved health in Africa: relevance, constraints and opportunities

Abstract. Good health status is one of the primary aspirations of human social development and, as a consequence, health indicators are key components of the human development indices by which we measure progress toward sustainable development. Certain diseases and ill health are associated with particular environmental and climate conditions. The timeframe of the Millennium Development Goals (MDGs) demands that the risks to health associated with current climate variability are more fully understood and acted upon to improve the focus of resources in climate sensitive disease control, especially in sub-Saharan Africa, where good epidemiological surveillance data are lacking. In the absence of high-quality epidemiological data on malaria distribution in Africa, climate information has long been used to develop malaria risk maps illustrating the climatic suitability boundaries for endemic transmission. However, experience to date has shown that it is difficult in terms of availability, timing and cost to obtain meteorological observations from national meteorological services in Africa. National health services generally find the costs of purchasing these data prohibitive given their competing demands for resources across the spectrum of health service requirements. Some national health services have tried to overcome this access problem by using proxies derived from satellites, which tend to be available freely, in 'near-real-time ' and therefore offer much promise for monitoring applications. This paper discusses the issues related to climate and health, reviews the current use of climate information for malaria endemic and epidemic surveillance, and presents examples of operational use of climate information for malaria control in Africa based on Geographical Information Systems and Remote Sensing
