As a French think tank for humanitarian and post-crisis aid, Groupe URD provides strategic guidance to public institutions (the Ministry for Europe and Foreign Affairs, the French Development Agency, the Auvergne-Rhône-Alpes Region and the European Commission, etc.) and aid organisations. Based on continuous exchanges with field actors, we engage in complementary activities that aim to improve aid practices: this approach feeds a collective learning process that helps to accompany organisations effectively. The complementary nature of these activities is one of Groupe URD’s strengths. As a result, following a study or an evaluation, we are able to provide the staff concerned with training or develop a tool to meet the needs that have been identified. Lessons can then be shared in a variety of ways, without always being made public (reports, videos, conferences, workshops, training courses, etc.).
