In Gibhe Valley in Tolay, the burden of malaria is particularly great and is one of the main reasons for the high child mortality rate here. The malaria control project in Ethiopia follows the same principles that were developed and maximised in pilot projects in Kenya(Malindi und Nyabondo).

The population is sensitised to the danger presented by malaria-transmitting mosquitoes on malaria information days. Breeding sites (e.g. pools) are dried out in community work, and blocked water channels are cleared so that water may flow again.

Where this is not possible, stagnant bodies of water are treated with an environmentally safe bacteria (Bti, Bacillus thuringiensis israelensis). Training of mosquito scouts from the local population helps to endure the long-term success of the project.
