A project of the Thomson Reuters Foundation, AlertNet is a news aggregator that aims to raise awareness of humanitarian crises around the globe, particularly 'forgotten' emergencies that rarely make headlines. It publishes news from over 400 aid agencies and other media outlets across a range of topics, from natural disasters to climate change to health. AlertNet also provides tools for journalists, including facts and figures, crisis briefings and training modules.

EM-DAT, run by the Centre for Research on the Epidemiology of Disasters at the Universite Catholique de Louvain in Belgium, provides statistics and data on disasters' impact on humans, such as the number of people killed, injured or affected as well as economic damage estimates and disaster-specific aid contributions.

Users can search the database or pull out summary information including graphs to show temporal trends as well as reference maps of disasters by type or date.

The Guardian Environment website publishes news and commentary on environmental issues such as climate change, energy, ethical living, food and recycling.

It also provides blogs, job listings and multimedia, including audio and video podcasts. Users can comment and are encouraged to join discussions.

The website also aggregates relevant news from members of the Guardian Environment Network, which brings together the world's best environment websites including SciDev.Net, China Dialogue, Real Science and the World Resources Institute.
