Mathis Wackernagel and William Rees describe the ‘ecological footprint’ (i.e. the ecological capacity, measured in hectares of biologically productive land, needed to supply a given person’s consumption of natural resources and absorb their waste) as a conception of environmental sustainability, and have accumulated significant data to measure the footprints of nations, cities and even individu...
Ecotourism, as the leading sector of the tourism industry, relies on utilizing environmental capabilities, and needs proper management decisions. In this context, the identification of ecological and environmental power is the most basic step. This study by considering the middle of the city as the sample of this province due to its ecological superiority and using the hierarchical analysis pro...
Development policy increasingly focuses on building capacities to respond to change (adaptation), and to drive change (innovation). Few studies, however, focus specifically on the social and gender differentiation of capacities to adapt and innovate. We address this gap using a qualitative study in three communities in Solomon Islands; a developing country, where rural livelihoods and well-bein...
Natural ecosystems have experienced widespread degradation due to human activities. Consequently, enhancing resilience has become a primary objective for conservation. Nature reserves are a favored management tool, but we need clearer empirical tests of whether they can impart resilience. Catastrophic flooding in early 2011 impacted coastal ecosystems across eastern Australia. We demonstrate th...
Sustainability science: accounting for nonlinear dynamicsin policy and socialâ•fiecological systems
Resilience is an emergent property of complex systems. Understanding resilience is critical for sustainability science, as linked social–ecological systems and the policy process that governs them have the capacity for nonlinear dynamics. The possibility of nonlinear change in these systems means that there is an inherent degree of uncertainty in social–ecological systems and the policy process...

Many physical diseases have been reported to be associated with psychosocial factors. In these diseases, assessment relies mainly on subjective symptoms in natural settings. Therefore, it is important to assess symptoms and/or relationships between psychosocial factors and symptoms in natural settings. Symptoms are usually assessed by self-report when patients visit their doctors. However, self...
Ecological momentary assessment and/or experience sampling methods are increasingly used in health studies to study subjective experiences within changing environmental contexts. In these studies, up to 30 or 40 observations are often obtained for each subject. Because there are so many measurements per subject, one can characterize a subject's mean and variance and can specify models for both....
The Ecological Footprint (EF) measure the natural capital demand of human activities (Wackernagel and Rees, 1996 and 2002) and reveal the sustainability of consumption patterns on individual, local, national and global scales (WWF, 2008). The ecological footprint measure the natural capital demand of human activities (Wackernagel and Rees, 1996) and reveal the sustainability of consumption patt...
