Disturbance Patterns in a Socio-Ecological System at Multiple Scales |

ZURLINI, G., B. JONES, K. RIITTERS, N. ZACCARELLI, I. PETROSILLO, AND L. ROSSI. Disturbance Patterns in a Socio-Ecological System at Multiple Scales. ECOLOGICAL COMPLEXITY 3(2):119-128, (2006).

| Abstract:
|
Ecological systems with hierarchical organization and non-equilibrium dynamics require multiple-scale analyses to comprehend how a system is structured and to formulate hypotheses about regulatory mechanisms. Characteristic scales in real landscapes are determined by, or at least reflect, the spatial patterns and scales of constraining human interactions with the biophysical environment. If the patterns or scales of human actions change, then the constraints change, and the structure and dynamics of the entire socio-ecological system (SES) can change accordingly. Understanding biodiversity in a SES requires understanding how the actions of humans as a keystone species shape the environment across a range of scales. We address this problem by investigating the spatial patterns of human disturbances at multiple scales in a SES in southern Italy. We describe an operational framework to identify multi-scale profiles of short-term anthropogenic disturbances using a moving window algorithm to measure the amount and configuration of disturbance as detected by satellite imagery. Prevailing land uses were found to contribute in different ways to the disturbance gradient at multiple scales, as land uses resulted from other types of biophysical and social controls shaping the region. The resulting profiles were then interpreted with respect to defining critical support regions and scale-dependent models for the assessment and management of disturbances, and for indicating system fragility and resilience of socio-ecological systems in the region. The results suggest support regions and scale intervals where past disturbance has been most likely and clumped - i.e. where fragility is highest and resilience is lowest. We discuss the potential for planning and managing landscape disturbances with a predictable effect on ecological processes.

Understanding the Effects of Air Pollution on Human Health |

PENNELL, W., J. M. SAMET, D. S. GREENBAUM, L. W. REITER, AND H. ZENICK. Understanding the Effects of Air Pollution on Human Health. EM: AIR AND WASTE MANAGEMENT ASSOCIATIONS MAGAZINE FOR ENVIRONMENTAL MANAGERS. Air & Waste Management Association, Pittsburgh, PA, 8-14, (2006).
|
| Abstract:
|
Modern air pollution regulation is first and foremost motivated by concerns about the effects of air pollutants on human health and secondarily by concerns about its effects on ecosystems, cultural artifacts, and quality of life values such as visibility. This order of priority is not surprising since a chief responsibility of government is to ensure the health and safety of its citizens. This article briefly describes what is known about the processes by which air pollutants can cause disease, and reviews how this knowledge informs the regulatory process.

CUPITT, L. T. Spatial Variability in Pollutants: Implications for Exposure Assessment. Presented at ISEE/ISEA International Conference on Environmental Epidemiology and Exposure, Paris, FRANCE, September 02 - 06, 2006.
|
| Abstract:
|
The efforts to evaluate the value of improved exposure metrics on the ability to relate those metrics with outcomes in complex systems have met with varying degrees of success. This work describes the results of recent efforts, mostly involving air pollutants, to improve the sophistication in the exposure estimate and classification in order to improve the quality of associations between exposure and outcomes at the end of the complex systems, both human and environmental.
