This study has been produced jointly by Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, a federally owned enterprise, implementing development programmes on behalf of the German Government, and CBM, a non-governmental organisation. Accordingly, its aim is to offer guidance to those in both governmental and non-governmental organisations on development cooperation. Given the wide and differing range of implementation procedures, levels of intervention and organisational cultures, it is not a ready-to-be-applied toolbox with concrete blueprints for action. Rather, it raises awareness on core human rights and disability – inclusive principles. It explains and illustrates the implications of applying these principles to development practice. Practitioners can therefore use the guidance to initiate a process of consideration of how to embed these principles within their programmes.
