DESCRIPTION
The Chinese Academy of Agricultural Sciences (CAAS) and the International Food Policy Research Institute (IFPRI) jointly hosted the International Conference on Climate Change and Food Security (ICCCFS) November 6-8, 2011 in Beijing, China. This conference provided a forum for leading international scientists and young researchers to present their latest research findings, exchange their research ideas, and share their experiences in the field of climate change and food security. The event included technical sessions, poster sessions, and social events. The conference results and recommendations were presented at the global climate talks in Durban, South Africa during an official side event on December 1.TRANSCRIPT

Introduction: CC and FS
Climate adaptation: linking CC and FS
UNFCCC Secretary, 15 February 2011
“On a global level, increasingly unpredictable weather patterns will lead to falling agricultural production and higher food prices, leading to food insecurity”
The Committee on World Food Security (CFS) requested to “review existing assessments and initiatives on the effects of climate change on food security and nutrition, with a focus on the most affected and vulnerable regions and populations and the interface between climate change and agricultural productivity, including the challenges and opportunities of adaptation and mitigation policies and actions for food security and nutrition”.
• The concern about China’s food security or the ability to feed itself. While Brown (1995; 2004), on the one hand, warns that the rising dependence on grain imports in China might affect the global food price significantly, others argue that China is capable of producing enough grain it needs in the 21st century (Rosegrant et al., 1995; Song, 1997).
• China is facing with considerable annual fluctuations of food production caused by climate variations and hazards. For example, in 1998 China produced 392 million tons of grain, but saw significant reductions in production in four of the following five years. In 2003, grain production was 326 million tons, a drop of more than 60 million tons in five years.
Importance of Food Security (FS) in China
• Under climate change, periods of drought are likely to become more frequent and severe;
• Water shortage, already a problem in China, may be exacerbated by climate change; and water shortages will further affect food production;
• In addition, decreases in water availability and food production would lead to indirect impacts on human health.
The Necessity of Linking CC and FS
ACCC Project: A Study to Improve FS
• The “Adapting to Climate Change in China” (ACCC) project provides a new way of thinking to link agricultural production with several climate stressors, which influence interactively food security and rural sustainability.
• This presentation focuses on ACCC project activities related to agricultural sector vulnerability and risks to climate variation and change, climate adaptation policies to reduce risks in food security.
• Major climate change adaptation project• China – UK – Swiss collaboration • NDRC main Chinese partner• 3 year project, June 2009-2012-• 48,000,000 RMB total• An integrated and interdisciplinary approach (IA)
which integrates major physical, biological, and socio-economic components of the whole climate change domain (ACCC, 2011)

Key Principles of ACCC 项目原则
• 合作——汇集中外专家专业知识
• Collaborative project – bringing together Chinese and international expertise
• 将气候变化作为跨领域问题研究
• Climate change as cross-sectoral issue • 提高恢复能力,降低风险
• Reducing climate risks by building resilience• 将适应对策即规划作为重点
• Focus on adaptation options and planning• 关注脆弱群体,如贫困社区、妇女和儿童
• Focus on vulnerable groups e.g. poor communities, women & children• 与其它国家进行知识分享
• Knowledge-sharing with other countries

Applying AHP in adaptation option prioritization
• The analytic hierarchy process (AHP) method has been used to prioritize alternative adaptation measures or options;
• Policy meetings have been held to identify sustainability indicators by water resource managers and farmers; and
• AHP surveys have been arranged with questionnaire to allow stakeholders and experts to evaluate adaptation options in the water sector in three case regions.
