Reliefweb is one of the main repositories of aid news. One of the lesser-known features of Reliefweb is briefing kit creator, an handy pre-mission informationtool.
The briefing kit creates your own overview of a humanitarian situation in a particular country or emergency operation, and puts it all in a single PDF file. You can select the information on basis of the country, the type of information (appeals, assessments, field reports,...), the source of the data (NGOs, government,...), the sector (agriculture, food, refugees,...).
The data includes situation reports, press releases, maps and other information, which can be generated and downloaded on the spot, or can be made in the background, and emailed to you after it is generated.
Here is a video explaining it all:
And of course, while you are on mission, continue to check Humanitarian News. With a simple search you'll get the latest articles on your interested subjects from over 600 different hand-selected information sources. You can even create your own RSS feed based on your search criteria.
