This new issue of the Poverty in Focus magazine presents 12 articles that discuss the main policy issues for a new inclusive and sustainable development paradigm. As a contribution to the dialogue around Rio+20 and to the ongoing discussions around a post-2015 MDG Agenda, this Poverty in Focus links future development to sustainability and particularly to social sustainability. Looking beyond the critical issues of ‘carbon footprints’, ‘low-carbon development’,’ green economy’ and the economics behind saving the planet, it draws attention back to the continuing challenge of ensuring that growth and development deliver for the poor and vulnerable. In its many forms—energy poverty, lack of access to water and sanitation, malnutrition or insecure access to food, and lack of access to education and health—the scale and scope of global deprivation call current development policy and practice into question.
