Mapping global inputs and impacts from of human sewage in coastal ecosystems
The authors use use a new high-resolution geospatial model to measure and map nitrogen (N) and pathogen—fecal indicator organisms (FIO)—inputs from human sewage for ~135,000 watersheds globally to assess the the potential impacts of human sewage on coastal ecosystems.
Political fragmentation and land use changes in the Interior Plains
Using the Interior Plains, the largest physiographic division of the US as study area, this paper investigates how political fragmentation in local governance can affect land use patterns through a watershed-level analysis of population and employment density changes.
Estimating the global burden of thalassogenic diseases: Human infectious diseases caused by wastewater pollution of the marine environment
Article presents a preliminary attempt at obtaining an order-of-magnitude estimate of the global burden of disease (GBD) of human infectious diseases associated with swimming/bathing in coastal waters polluted by wastewater, and eating raw or lightly steamed filter-feeding shellfish harvested from such waters. Such diseases will be termed thalassogenic - caused by the sea. (from Abstract)
Seasonal water discharge and sediment load changes in the Upper Yangtze, China.
Author finds that that most of the seasonal water discharge and sediment load changes in the Upper Yangtze were caused by human activities such as deforestation, water use, and construction of reservoirs rather than by decadal climatic variations, and that the changes in some tributaries had significant implications with respect to flooding and water shortages.
In search of water in Karnataka, India: Degradation of natural resources and the livelihood crisis in Koppal District.
Article deals with the groundwater, agricultural, and population consequences of resource depletion due to rock blasting and stone cutting.
Challenges of data integration in the study of a complex system: A case study of Lake Atitlán in Guatemala.
The watershed of Lake Atitlán on the Highlands of Guatemala is presented as an example of the high level of complexity found in a system that involves natural, social, and economic forces interacting in a small but extremely diverse geographical area. This paper describes our efforts to use a multidisciplinary approach to study the two main forces of natural and social change in the area: coffee production and tourism, as well as to understand how these interact with a highly intertwined system of institutions.
Migration, remittances, livelihood trajectories, and social resilience.
Paper discusses the effects of demogrpahic change, including migration, on social resilience, and use of the natural resource base. In the communities studied the authors find that emigration is concurrent with, but not driving, unsustainable agriculture.
Conflict and cooperation over international freshwater resources
The Basins at Risk project attempts to fill several gaps in research on freshwater resources and international conflict and includes: 'a methodology for identifying and classifying events by their intensity of cooperation and conflict; construction of a geographic information system (GIS) of countries and international basins, both current and historical; and the collection or creation of indicator variables (biophysical, socioeconomic, and geopolitical) for testing of hypotheses about factors associated with water conflict."
Water management in the binational Texas/Mexico Rïo Grande/Rïo Bravo Basin
Difficult, but pressing, challenges demand that policymakers begin looking at water management in the Rï''o Grande basin in new ways. In addition to increasing public awareness of the limits on water supply in the basin, long-held notions about the relationships among growth management, economic development and water supply, as well as about how water should be used in urban and rural areas, will have to be re-examined.
