This publication highlights the outcomes of the climate-smart livelihoods programming implemented under the Pilot Programmatic Partnership (PPP) between the European Commission’s Civil Protection and Humanitarian Aid Operations Department and the International Federation of Red Cross and Red Crescent Societies (IFRC). Through case studies of activities in Burkina Faso, the Democratic Republic of the Congo, Ecuador and Honduras, it explores the role of National Societies in addressing climate-related humanitarian challenges that impact on livelihoods among marginalized communities, and climate-smart livelihoods programming as a solution.
