• They may involve the building of an expensive, prestigious building such as a hospital - which will mainly help the urban rich
• It will involve technology which is inappropriate - a tractor is not much use if there are not spare parts or diesel fuel available locally
• Large scale projects such as dams may damage the environment and force people off the land
• Some projects have suffered from corruption - the help has not gone to the people who need it but politicians and officials have greatly benefited
