Improving Freedom of Information in Uganda

Uganda is one of only 10 African countries with a national access to information (ATI) law. These types of laws are essential to human rights, providing citizens with legal access to the government-held information that directly impacts them—information on issues like mining permits, logging concessions, air quality data, and more. But as researchers are learning, ATI laws on the books do ...
