Government officials, representatives of UN bodies and agencies, intergovernmental organizations and civil society organizations are meeting at COP20 in Lima, Peru, to discuss a new global climate change agreement. Since the notion of agriculture is not on the agenda, The Technical Centre for Agricultural and Rural Cooperation ACP-EU (CTA) and other organisations working in agriculture and rural development are striving to establish formal arrangements for addressing agriculture within the next UN Climate Change negotiations. As week two of COP 20 gets into full gear, we urge you to join the online discussion by tweeting #cop20 or #foodsecurity.
