REACT - Remote sensing for Epidemiology in African CiTies

You are here

Context and objectives

According to the World Health Organization (WHO), it is estimated that 90% of all malaria deaths worldwide occur in Africa. Malaria intervention across the continent remains focused on rural, highly endemic communities. Yet, urban malaria in sub-Saharan Africa is a major health problem that is likely to become increasingly important. Up to now, the heterogeneity of intra-urban malaria risk has not been captured in continental risk-mapping initiatives and the inter-urban risk variations have not been taken into account in malaria risk modelling. REACT aims to harness the potential of remote sensing and spatial modelling at different spatial and temporal scales to improve the spatial understanding of intra- and inter-urban malaria risk variations in sub-Saharan Africa.

Project outcome

Expected scientific results

  • Innovative methods for deriving climatic, environmental, demographic and socioeconomic variables from VHRRS, HRRS and L/MRRS
  • Better insight into temporal and spatial variations of meteorological conditions in SSA cities
  • Better insight into environmental trends, cyclical components and rapid change events in SSA cities
  • Better insight into spatial variations of demographic and socioeconomic characteristics in SSA cities
  • Intra-urban predictions of malaria infection risk across 4 SSA cities
  • Better understanding of the variations of malaria infection risk between SSA cities
     

Expected products and services

  • Tools and methods for faster and less labour-intensive alternatives for targeted and effective disease
  • Control
     

The main stakeholders of the REACT project are policy makers based in the local and governmental ministries of low-income countries, in support to development, health and planning policies.
