Yin Yongyuan — Adapting to climate change and enhancing food security in china


Published on

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.

Yin Yongyuan — Adapting to climate change and enhancing food security in china

  1. 1. Adapting to Climate Change and Enhancing Food Security in China 气候变化适应和增强中国粮食安全 ICCCFS Conference, Beijing, 2011-11-8Yongyuan Yin, Xu Yinlong, Emanuele Cuccillato, Ellen Kelley, Pan, X.B.,Wang, G.Q. and Declan Conway
  2. 2. Outline Introduction: CC and FS Climate adaptation: linking CC and FS ACCC project: interdisciplinary and IA概要 Project activities and achievements Science and policy integration Conclusions
  3. 3. “On a global level, increasingly unpredictable weatherpatterns will lead to falling agricultural production andhigher food prices, leading to food insecurity”The Committee on World Food Security (CFS) requested to“review existing assessments and initiatives on the effects ofclimate change on food security and nutrition, with a focus on themost affected and vulnerable regions and populations and theinterface between climate change and agricultural productivity,including the challenges and opportunities of adaptation andmitigation policies and actions for food security and nutrition”. UNFCCC Secretary, 15 February 2011
  4. 4. Importance of Food Security (FS) in China• 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.
  5. 5. The Necessity of Linking CC and FS• Under climate change, periods of drought arelikely to become more frequent and severe;• Water shortage, already a problem in China,may be exacerbated by climate change; andwater shortages will further affect foodproduction;• In addition, decreases in water availability andfood production would lead to indirect impactson human health.
  6. 6. ACCC Project: A Study to Improve FS• The “Adapting to Climate Change in China”(ACCC) project provides a new way of thinking tolink agricultural production with several climatestressors, which influence interactively food securityand rural sustainability.• This presentation focuses on ACCC projectactivities related to agricultural sector vulnerabilityand risks to climate variation and change, climateadaptation policies to reduce risks in food security.
  7. 7. • 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)

  9. 9. 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
