The Early Warning System (EWS) supports governments and industry specific stakeholders goal across Africa of safeguarding agricultural resources by ensuring that new introductions of harmful invasive pests are detected as soon as possible, before they have a chance to cause significant damage.
This website provides a portal to information and maps on identifying, recording, trend analysis and the Early Warning System on Africa’s invasive species.
Preventing the introduction of invasive species is the first line of defense against invasions. However, even the best prevention efforts will not stop all invasive species introductions. Our Early Warning Detection efforts increase the likelihood that invasions will be noticed successfully while populations are still localized and population levels are not beyond that which can be contained and eradicated. Once populations are widely established, all that might be possible is the partial mitigation of negative impacts.
In addition, the costs associated with large area eradication and control efforts are typically far more than those of long-term invasive species early warning and detection systems.
