The goal of the Humanitarian Early Warning System is “to bring together and make accessible in a simple manner the most credible early warning information available at the global level from multiple specialized institutions.” Basically, it is a early warning system for all natural hazards. It is developed and maintained by the UN World Food Programme, HEWS has services dedicated to floods, seismic (earthquakes), storms, locust, volcanoes and weather. This tool is user friendly, and a great example of Geographic Informational System (GIS).
I think a lot of other early warning systems while I was quickly researching focused on everything included in HEWS but the locust. The locust took me by surprise, although it does makes sense in the context of Africa. The website says its 70% dynamically updated with real-time information, which still leaves 30%. This is obviously a significant number that leaves stakeholders in question of the data. I think this is a better system for NGOs and multilateral organizations that focus on disaster management, rather than the actual targeted citizens affected by the disaster because I think people usually get their information fro news sources or some may not have access to the internet to check this system.
