Atrazine Monitoring and Modeling in the Lake Lavon Watershed

Description: This report describes a study to identify the distribution and extent of areas potentially at risk for atrazine (a broad leaf weedkiller) runoff in the Lake Lavon watershed, which is a major water supply for the Dallas area. The report presents the results of the study and makes recommendations for how information can be used in a cost-effective watershed atrazine reduction strategy.

Report of Planning Workshop on MAIRS Mountain Zone Implementation

Description: Monsoon Asia Integrated Regional Study (MAIRS) is an IRS research program over monsoon Asia under START and the Earth System Science Partnership (ESSP). It was established to address questions about the coupled human and environment system in the monsoon Asia region. The vision of MAIRS is to significantly advance understanding of the interactions between the human and natural components of the overall environment in the monsoon Asian region and implications for the global earth system, in order to support strategies for sustainable development. Regional-scale studies of global change provide the knowledge base for undertaking vulnerability analyses, identification of hotspots of risk and studies of environmental degradation which are crucial for the sustainable development. Regions may manifest significantly different environmental dynamics, and changes in regional biophysical, biogeochemical and anthropogenic components may produce considerably different consequences for the earth system at the global scale. Regions are not closed systems and thus the linkages between regional changes and the global earth system are crucial. This specific report focuses on Planning Workshop on MAIRS Mountain Zone Implementation that held in China. Integrated Regional Studies (IRSs) should have relevance for people living in the regions and should provide a sound scientific basis for the sustainable development of the countries in the regions, and IRSs are also important from an earth system science perspective.

Global Change and Mountain Regions: The Mountain Research Initiative

Description: The strong altitudinal gradients in mountain regions provide unique and sometimes the best opportunities to detect and analyse global change processes and phenomena. Meteorological, hydrological, cryospheric and ecological conditions change strongly over relatively short distances; thus biodiversity tends to be high, and characteristic sequences of ecosystems and cryospheric systems are found along mountain slopes. The boundaries between these systems experience shifts due to environmental change and thus may be used as indicators of such changes. The higher parts of many mountain ranges are not affected by direct human activities. These areas include many national parks and other protected environments. They may serve as locations where the environmental impacts of climate change alone, including changes in atmospheric chemistry, can be studied directly. Mountain regions are distributed all over the globe, from the Equator almost to the poles and from oceanic to highly continental climates. This global distribution allows us to perform comparative regional studies and to analyse the regional differentiation of environmental change processes as characterised above. Therefore, within the IGBP an Initiative for Collaborative Research on Global Change and Mountain Regions was developed, which strives to achieve an integrated approach for observing, modelling and investigating global change phenomena and processes in mountain regions, including their impacts on ecosystems and socio-economic systems.

Regional Assessment of Water Quality: Trinity River Basin

Description: The purpose of this study is "to identify significant issues affecting water quality" within the Trinity River watershed, located in the eastern half of Texas, "and to provide sufficient information for the Commission, river authorities, and other local government bodies to take appropriate corrective action necessary to maintain and improve the quality of [the] state's water resources" (p. [1]).

Remote Sensing and GIS for Nonpoint Source Pollution Analysis in the City of Dallas' Eastern Watersheds

Description: This report describes the findings of a study conducted on the Eastern Watersheds of Lake Lavon, Lake Ray Hubbard, Lake Tawakoni, Lake Palestine and Lake Fork, which are located within the Blackland Prairie, Post Oak Savannah and Pineywoods provinces. These watersheds are among nine that provide drinking water to Dallas, Texas. The study examines the potential benefit of "remote sensing and geographic information systems (GIS) for watershed management" in these five watersheds (p. iii).

Remote Sensing and GIS for Nonpoint Source Pollution Analysis in the City of Dallas' Western Watersheds

Description: This report describes the findings of a study conducted on the watersheds of "Lake Lewisville, Lake Ray Roberts, Lake Grapevine and the Elm Fork of the Trinity River between Lake Lewisville and Frazier Dam," which are all part of the upper Trinity drainage basin (p. 31). The study examines the potential benefit of "remote sensing and geographic information systems (GIS) for watershed management" in and around Dallas, Texas (p. i).

A Socio-ecological Assessment of Watershed Ecosystem Services in Southern Patagonia

Description: This thesis utilizes a theoretical framework which links biophysical and social domains of ecosystems via ecosystem services (ES), in order to conduct a socio-ecological assessment of urban watersheds in three communities in Chilean and Argentine regions of southern Patagonia. Results from this study show that expanding urban areas may be undermining the ability of local watersheds to provide for high quality ES posing potential risks to community wellbeing. Secondly, researchers and decision makers influencing regional natural resource management share similar values to general community members but do not capture the diversity of values that exist within the broader community, and dialogue between these groups on management issues is poor. A community-based management structure is recommended for the creation of adaptive and locally relevant management strategies.
