International cooperation in ground-based astronomy

The UN/ESA workshops aim to foster the development of basic space science i n developing countries. It is argued that the involvement of these countrie s in international collaborations in ground-based astronomy is an effective method of achieving this aim. A brief analysis of patterns of internationa l cooperation in ground-based astronomy is presented. Where possible, the d iscussion is illustrated with examples chosen to highlight contributions by developing countries. Mechanisms to support international cooperation are discussed, along with some problems and possible solutions.
