This thesis intervenes in one of the most prominent recent debates in development theory – that between post-development theorists and their critics – and brings to it insights drawn from the experiences of a Senegalese non-governmental organisation, Enda Graf Sahel. I begin by providing a critical discussion of the post-development debate and then detail the question which guides this investigation, namely: how can we, the relatively privileged, respond meaningfully to poverty and injustice in the light of the post-development debate? I present three possible responses to my research question. Firstly, I argue that the relatively privileged have a role to play in rethinking the concepts of ‘poverty’ and ‘injustice’. Secondly, I discuss the kinds of support that we may provide to popular organisations; and finally, I describe ways in which those of us who are relatively privileged may change aspects of our own lives and settings in solidarity with the struggles of the poor and oppressed. Throughout, I draw extensively both on the post-development debate and on the experiences and insights of Enda Graf Sahel to show how we can move past a simple defence or rejection of post-development theory in order to meaningfully respond to poverty and injustice.
