Projects & Publications
Each project is summarised to describe the work of the research grant recipients and their intended impact and outputs. This view shows projects mapped to the locations where the research was carried out.
Projects have been assigned one of eight primary cross-cutting themes. To see all the projects grouped under a particular theme click on that topic in the menu bar. You can also use the search fields to find projects or their related outputs grouped by country, keywords, location, organisation, or people who were the named grantees for the project or publication authors. You can make multiple selections. Use The Impact Initiative logo in the top left of the screen or the home icon to return to the home page.
