It is expected to impact upon the climatic conditions on China’s Loess Plateau, principally through prolonged variations in rainfall and droughts, pushing communities and farmers beyond their current adaptive capacity. There is an urgent need for assistance in building resilience and undertaking climate change adaptation efforts in order to reduce the vulnerability of social-environmental systems and farmers' livelihoods on the Plateau. The social-environmental systems on China’s Loess Plateau are unique in that they are extremely dynamic and fragile due to severe deforestation, soil erosion, water stresses, and poverty, which have occurred over many centuries. Two remarkable and vast programs, the Loess Plateau Watershed Rehabilitation Program (1994-2005) by the World Bank, and the national Grain for Green (1999-current) project, to a large extent, have made the social-environmental systems on the Plateau more resilient to environmental stresses. However, neither of these two initiatives has integrated climate change scenarios into planning, design or implementation. It reveals that emerging vulnerabilities to climate change have already affected these initiatives’ long-term sustainability. For instance, trees planted died due to severe water scarcity and farmers’ were forced to re-farm retired land due to reduced farm income caused by unfavorable climatic effects. Therefore, the integration of climate change implications into the policy-making processes and adaptive management strategy are keys to enhancing the resilience of social-environmental systems on the Plateau. The case study area of Huachi explores in greater depth the vulnerability of agriculture and farmers’ livelihoods to climate change. It identified the following adaptive strategies currently available to local farmers: cultivation of drought resistant crops and varieties; water-saving agricultural technologies; and non-farm employment. It has been found that farmers’ resilience to the adverse effects of changing climatic conditions has been improved. The results also found that main factors can enhance farmers’ adaptive capacity are farmers’ knowledge and skills; access to climate information, farming technology and infrastructure; access to markets, farmland tenure and off-farm activities. These findings have considerable relevance for the Chinese Government in their efforts to develop policies aimed at improving these factors.

I would like to take this opportunity to express my gratitude to all those people who have given their invaluable support. In particular, I am deeply indebted to my supervisor, A/P John Merson and co- supervisor, Visiting Fellow Mr. Sandy Booth. They are very generous with their time, knowledge and encouragement, professionally assisting me in each phase to complete the thesis. In addition, I should like to thank Professor LIU Yonggong from the College of Humanities and Development at China Agricultural University, who gave me important and indispensable advice on my thesis both in person and on the phone. Many thanks also to Mr. ZHAO Hua from Gansu Water Resource and Soil Conservation Bureau, and Mr. WEI Guoji from Huachi Water Resource and Soil Conservation Bureau, for helping to arrange the fieldwork for me; and particularly to local farmers in Huachi for their remarkable hospitality and for their participation in interviews and discussions. This thesis was financially supported by the ‘Australian Leadership Awards Scholarship’, which was offered by the Australian Agency for International Development (AusAID). The Faculty of Arts and Social Sciences at the University of New South Wales further financed my fieldwork in China in 2009. I gave my great thanks to these organisations. And finally, but not least, I’d include my friends, colleagues, and my family who are highly appreciated for their spiritual support, particularly my husband, ZHANG Hui to whom this thesis is dedicated.
