摘要：The complexity of social-ecological systems is well recognized (Berkes et al. 2003, Norberg and Cumming 2008).However, in the study of such systems, it is often the uncertainty that results from nonlinear interactions that forms the focusof discussion. Here, the normative implications of complexity for our knowledge of such systems are emphasised, by drawinglargely on the work of Cilliers (1998, 2005a), who introduced the term "critical complexity." This perspective on complexityis distinct in bringing the value-based choices that frame our knowledge generation strategies to the fore. It is from this viewthat we investigate the implications of complexity for social-ecological systems research. Based on these implications, wepropose a set of five key questions to guide the incorporation of insights from critical complexity into such research. We endwith a brief application of the questions proposed to the National Freshwater Ecosystem Priority Areas (NFEPA) project inSouth Africa, to illustrate their potential use in the context of resource management
