Book Description
Land-use and land-cover (LULC) change is a continuous and dynamic process that is driven by human-induced activity. The North River watershed, located in Alabama, exemplifies patterns of forestry practices related to commercial logging that are present with the increasing frequency of intensive forestry practices across the Southeastern U.S. While many studies focus on expanding urbanization within watersheds and the effect on hydrology, there is a need to study effects on hydrology of newer forestry practices, which promote shorter regeneration and growth periods with more frequent tree harvest. Using the Soil and Water Assessment Tool (SWAT), a GIS hydrologic modelling program using watershed data (LULC, soil weather, elevation), a calibrated and validated model (NSE: 0.74 and 0.63, respectively) was produced and run for the study period of 2001-2018. LULC change trends between six NLCD LULC change periods (2001 to 2004, 2004 to 2006, 2006 to 2008, 2008 to 2011, 2011 to 2013, and 2013 to 2016) were examined and the impact on both discharge and water-balance components were analyzed. Using a KS-test on the distribution of climate de-trended monthly simulated discharges, three LULC change scenarios revealed statistically different distributions. With net forest loss in the watershed, water yield and subsequent discharge values increased; scenarios with forest gain resulted in water yield and discharge decreasing through various water-balance components analyzed in SWAT. These results suggest that LULC change can have effects on the hydrologic cycle with impacts on water yield through alteration of the water-balance variables.

Book Description
This is a progress report on the Black Creek sediment control project. This project is to determine the environmental impact of land use on water quality and has completed its third year of watershed activity. The project, which is directed by the Allen County Soil and Water Conservation District, is an attempt to determine the role that agricultural pollutants play in the degradation of water quality in the Maumee River Basin and ultimately in Lake Erie.

Book Description
With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.

Book Description
Ecosystems and Human Well-Being is the first product of the Millennium Ecosystem Assessment, a four-year international work program designed to meet the needs of decisionmakers for scientific information on the links between ecosystem change and human well-being. The book offers an overview of the project, describing the conceptual framework that is being used, defining its scope, and providing a baseline of understanding that all participants need to move forward. The Millennium Assessment focuses on how humans have altered ecosystems, and how changes in ecosystem services have affected human well-being, how ecosystem changes may affect people in future decades, and what types of responses can be adopted at local, national, or global scales to improve ecosystem management and thereby contribute to human well-being and poverty alleviation. The program was launched by United National Secretary-General Kofi Annan in June 2001, and the primary assessment reports will be released by Island Press in 2005. Leading scientists from more than 100 nations are conducting the assessment, which can aid countries, regions, or companies by: providing a clear, scientific picture of the current sta
