The impacts of climate change on livestock production are complex problems, existing in the relationship among this sector and others sectors such as environmental, social, economic and political systems. The complexity and dynamic of these impacts cannot be solved simply in isolation with the linear approach. A system thinking methodology is introduced in this paper to understand the impacts of climate change on livestock production, and identify effective interventions strategies to address this systemic problem. System thinking is a way of thinking about the world and relationships which has been developed far along way in the past. Today, systems thinking has become increasingly popular because it provides a 'new way of thinking' to understand and manage complex problems, whether they rest within a local or global context. While four levels of thinking is a fundamental tool to identify systemic problems, Causal Loop Diagram (CLD) is a visual tool created by a computer program to illustrate the whole picture of climate change impacts. CLD consist of feedbacks for system, which help strategists identify appropriate intervention strategies in solving the systemic problem.
