Zaccarelli, N., I. Petrosillo, G. Zurlini, and K. Hans Riitters 2008. Source/sink patterns of disturbance and cross-scale mismatches in a panarchy of social-ecological landscapes. Ecology and Society 13(1): 26. https://doi.org/10.5751/ES-02416-130126
Highlights
Land-use change is one of the major factors affecting global environmental change and represents a primary human effect on natural systems, and underlying fragmentation and habitat loss, which are the greatest threats to biodiversity (Alcamo and Bennett 2003)
By using moving windows to measure composition and spatial configuration of disturbance, we identify multiscale disturbance source/sink trajectories in the pattern metric space defined by composition and configuration of disturbance
Through the framework outlined in our examples, managers, as well as stakeholders belonging to social-ecological landscapes (SELs) in the panarchy, can be aware of specific scale ranges of disturbance where mismatches might occur and that will help them to value where and how to intervene in the panarchy of SELs to enhance the benefits and to minimize negative effects
Summary
Land-use change is one of the major factors affecting global environmental change and represents a primary human effect on natural systems, and underlying fragmentation and habitat loss, which are the greatest threats to biodiversity (Alcamo and Bennett 2003). Since human land use is a major force in driving landscape change, landscape dynamics can be better understood in the context of complex adaptive socioeconomic and ecological systems (e.g., Berkes and Folke 1998), integrating phenomena across multiple scales of space, time and organizational complexity. In the real geographic world such systems can be better defined as social-ecological landscapes (SELs), taking into account the scales and patterns of human land use as ecosystem disturbances. Worldwide losses of biodiversity have occurred on an unprecedented scale and agricultural intensification has been indicated as a major driver of this global change Agricultural intensification is determined by practices on both local and landscape scales (e.g., Matson et al 1997, Tilman et al 2002). It is due to Ecology and Society 13(1): 26 http://www.ecologyandsociety.org/vol13/iss1/art26/
