Climate change – both natural and anthropogenic – will lead to significant global and local changes in the near future. Agriculture is contributing significantly to GHG emmissions, but will also be among the sectors most severely impacted by changes in climate patterns. Climate change will affect all four dimensions of food security: food availability, food accessibility, food utilization and food systems stability. The next Brussels Development Briefing will focus on ‘Climate change, agriculture and food security: proven approaches and new investments’. It will address issues related to agriculture and food security in a changing climate, and how agriculture can increase resilience to climate change effects. In particular, it will: (i) raise awareness in ACP countries on the key challenges posed to agriculture by climate changes; (ii) increase exchange of information and expertise on strategies to develop climate-smart agriculture and proven successes; and (iii) facilitate networking among development partners. The briefing, wich will be held on 27 September, 2012, will be organized in collaboration with the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). Around 120 ACP-EU policy-makers and representatives of EU Member States, civil society groups, research networks and development practitioners, and international organizations based in Brussels.
