The document discusses Ushahidi and Growdmap, which are crowdsourcing tools. Ushahidi was created in 2008 to map reports of violence in Kenya and has since been used for other crisis mapping and public reporting purposes. Growdmap is a derivative of Ushahidi's platform that allows users to collaboratively map local issues and events. The document then covers topics like how crowdsourcing works, how people can participate through social media and other means, and examples of crowdsourcing being used for issues reporting.
