Maternal health has become a top global priority. In contrast to the decline of the maternal subject (Stephens, 2011), and despite previous evidence that maternal health has struggled to find a place on the global policy agenda (Shiffman and Smith, 2007), it is now clear that the promotion of health for mothers and children is a staple of both government and private donor commitments. On humanitarian grounds, it makes sense to focus on maternal health and survival in the Global South. (...) Death related to pregnancy or childbirth is a disheartening example of needless suffering. But beyond the initial impulse to reduce suffering, what motivates and/or requires action for addressing injustice in the form of distributional inequities for maternal and reproductive health? In this article, I make a case for the necessity and validity of transnational cooperation to address maternal mortality and morbidity in the Global South. The first component of my argument addresses the transnational elements of both global interconnectedness and responsibility to act. These elements are drawn from Iris Marion Young’s philosophical justification for North-South responsibility-taking. The second component of my argument adds the concept of affective solidarity to that of transnational responsibility. My argument in this section draws from Iris Marion Young’s earlier work on identity (Young, 1990) and embodiment (Young, 1984) and expands the analysis of affective solidarity as a form of both embodiment and political commitment in order to explain the mechanism for transnational connection and understanding. And the final component of my argument explains how both of these elements – transnational responsibility and affective solidarity – support a theory of transnational maternal feminism. (shrink)
