Avian Influenza Risk AssessmentEfforts in risk assessment of highly pathogenic avian influenza (HPAI) and response strategies are to a large degree hampered by (a) the lack of a comprehensive understanding of the ecology of avian influenza, particularly the relationship between domestic poultry and wild waterfowl; and (b) the fact that geospatial datasets used for risk assessment strategies are often out-of-date and at coarse spatial (national or provincial) and temporal (annual) scales. Geospatial technology (satellite remote sensing, GIS) could potentially play an important role in providing dynamic and timely information to support risk assessment and early warning of HPAI. Environmental Geosolutions participated in the remote sensing component of a FAO-funded effort to generate a geospatial risk assessment system for HPAI. The system includes inputs that are ecological (e.g. waterfowl flyways, wetland locations), epidemiological, and social (agriculture management) and will be distributed in near real-time through a custom Google Earth interface. |
