"The Piasa Creek Watershed (PCW) was once a landscape historically comprised of forest and prairie habitat, but today is largely comprised of agriculture and urban lands. Studies carried out in the watershed have shown stream biology, mainly fish, and water quality to have declined over time. In the PCW, macroinvertebrate bioassessments of water quality and land use have largely been underutilized. Benthic macroinvertebrates were sampled during October 2011 from riffle habitats at 19 unique locations throughout the PCW in order to examine water quality as a function of land use. Collections were based on rapid bioassessment procedures with a minimum of 125 organisms sampled and identified to the family level, and summarized using a suite of metrics. Water quality ratings were determined using the Hilsenhoff Biotic Index (HBI) which incorporated regional pollution tolerance values. Data analyses with multiple regression were used to evaluate relationships between macroinvertebrate metrics and land use coverage. Non-metric multi-dimensional scaling (NMDS) of community assemblages in combination with vector fitting procedures were employed to evaluate the effects of land use on communities. Data interpretation was assisted with the use of an analysis of similarity between communities of different stream orders and an indicator species analysis. Communities were obtained from 3rd through 6th order streams. In total, 5,345 organisms from 56 unique families of benthic invertebrates were identified. Predominant land uses included grass/pasture, agriculture, forest, and urban cover types. On average, water quality was rated as "fair" but ranged from "good" to "poor" using the HBI scale. Communities differed by the percentage of agriculture and forest land use in each watershed, as well as stream order, with those from 3rd order streams different from higher orders. Certain families of invertebrates discriminated among groups of stream sites, six families were indicative of 3rd order streams and two taxa were indicative of sites from higher orders. While the lack of significant relationships between land use and macroinvertebrates is weak, the results are based on a relatively small sample size which may have limited the scope of findings. Overall, the composition of macroinvertebrate communities in the PCW suggests water quality is impaired to some extent. An increase in the percentage of agricultural land cover affected community composition, and this land use is at least partially the source of water quality impairment. Additionally, community composition was also influenced by the percentage of forest land cover, and sites with the best water quality contained watersheds of mostly forest habitat. The relationship between land use and community composition is likely influenced by changes to riparian and in-stream habitat in addition to water quality. Stream systems in the PCW are likely influenced by land use at multiple spatial scales, however, findings from this study suggest the relationship does in fact extend to the watershed level. While addressing water quality and stream habitat issues in the PCW is a complex task, it may be beneficial to employ best management practices at key areas further out in the watershed to address water resource needs in the PCW."

The 21st century presents many challenges to the hazard manager; dynamic climatic conditions combined with population growth, rapid urbanization, and changing socio-economic relationships are reshaping disaster impacts, community responses, and social safety mechanisms. Indeed, human vulnerability is constantly restructured by the ongoing interplay of physical, social, economic, and political forces. At the same time, reducing vulnerability and enhancing community resilience require policies aimed at mitigating the consequences of disasters as they affect different locations and different groups, requiring sound scientifically-based research to further an understanding of the forces at play, and to devise appropriate means to counter them. It is within this context that this book examines evolving approaches to natural hazards. Research into natural hazards has a long tradition beginning with a focus on physical processes and evolving into an interdisciplinary agenda that incorporates interactions between the physical and human environments, embracing initiatives ranging from the physical to the socio-economic and political. It utilises various methodological approaches and technological advances, employing both quantitative and qualitative procedures. The papers included in this book offer insights into the development of applied hazards research, as they build on previous work, evolving technologies, improved understandings of the factors involved, and increased awareness of the needs of those who manage hazards. This volume shows an appreciation for the foundation that has been set, and will inspire future researchers as they look to address these very pressing social issues.
