The debate on growth and development that has been going on over the last decades has clearly highlighted a number of flaws and contradictions that the theory, as well as the practice, of International Development Cooperation (IDC) has failed to address in a convincing and effective way. IDC, once the prime tool for promoting a change in the livelihoods of the poorest and most vulnerable, is increasingly under scrutiny and does not seem to have provided an effective response to the current crisis. Buen Vivir (good life), Latin America's new concept for collective well-being, which has emerged over recent years from the traditional cosmovisions of Andean indigenous peoples and translated into political and institutional practice, offers elements of reflection on economy, environment and social life that are useful for reframing the way 'well-being' is conceived within the current development setting: a fresh perspective on the most urgent global concerns is particularly useful as the debate regarding the successors to the Millennium Development Goals post-2015 starts to heat up. The new approach to IDC developed in Ecuador in recent years represents an attempt to put some of these elements into practice. However, beyond the experiences in Latin America, that can claim a closer link, albeit not without tensions, with the indigenous peoples with which the Buen Vivir culture has its roots, these suggestions can show an interesting convergence with alternative views on development emerging from the reflections and practices of Western social movements.
