Download The Land-use Change Analysis System (LUCAS) for Evaluating Landscape Management Decisions Book in PDF, ePub and Kindle
Abstract: "Ecological dynamics in human-influenced landscapes are strongly affected by socioeconomic factors that influence land-use decision making. Incorporating these factors into a spatially-explicit landscape-change model requires integrating multidisciplinary data. In order to study the effects of land use on landscape structure in regions such as the Little Tennessee River basin in western North Carolina and the Olympic Peninsula of Washington state, we have developed the Land Use Change Analysis System or LUCAS for UNIX-based workstations. The map layers used by LUCAS are derived from remotely-sensed images, census and ownership maps, topographical maps, and outputs from econometric models. These map layers are stored, displayed, and analyzed using a public-domain Geographic Information System (GIS). Simulations using LUCAS generate new maps of land cover representing the amount of land-cover change so that issues such as biodiversity conservation, assessing the importance of landscape elements to meet conservation goals, and long-term landscape integrity can be addressed."

Download Change Analysis of Watersheds Using Remote Sensing & GIS Applications Book in PDF, ePub and Kindle
Evaluation of watersheds and development of a management strategy requires accurate measurement of the past and present land cover/land use parameters as changes observed in these parameters determine the hydrological and ecological processes taking place in a watershed. Present study was thus focused on presenting a comparative case study for detecting the change analysis of two watersheds in Islamabad, namely Rawal and Simly Watershed using satellite data obtained from Landsat 5 and SPOT 5 for the years 1992 and 2012 respectively. Land cover and land use change was detected by applying Supervised classification-maximum likelihood algorithm in ERDAS IMAGINE and five land classes were delineated viz., Agriculture, Bare soil/Rocks, Settlements, Vegetation and Water. Furthermore, land cover/land use and overlay maps for both Watersheds were created in ArcGIS. Achieved overall classification accuracies were 95.32% and 95.13%, while Kappa statistics were 0.9237 and 0.9070 for the final land cover/use maps of 1992 and 2012 respectively.

Download An Integrated Assessment of Watershed Land Use Impacts on Aquatic Ecosystem Integrity Book in PDF, ePub and Kindle
According to a 1996 report to congress, the Environmental Protection Agency stated that nutrients, primarily from agriculture, are the most common pollutants affecting lakes and constitute 49% of all the water quality problems that have been identified in lakes. Therefore, there is a strong need to evaluate the agricultural and other anthropogenic factors that contribute to the degradation of aquatic ecosystems-especially in areas that are dominated by agriculture. This project takes a watershed approach to analyzing water quality issues by evaluating agricultural land use impacts on indicators of aquatic ecosystem integrity. This approach incorporates the diverse aspects of agricultural and aquatic ecosystems through the use ofbiophysical models and a geographic information system (GIS).
