Time series segmentation techniques for land cover change detection
… understanding the location and extent of global land cover change. In this study, we focus on time series segmentation techniques in the context of land cover change detection. We propose a model based time series segmentation algorithm inspired by an event detection framework proposed in the …

Modeling land-cover change in the Amazon using historical pathways of land cover change and Markov chains. A case study of Rondõnia, Brazil
… farmers firstly using only pathways of past land cover change and secondly using demographic, socioeconomic and land cover data at the farm level. The second purpose is to compare the explanatory and predictive capacity of both approaches at identifying areas at high risk of deforestation …

Patterns of land cover change in Kanyati communal land in Zimbabwe
… trend with significant effects on existing land cover types and ecosystems. High rates of human population growth in southern Africa and subsequent increased pressure on land has led to the extension of cultivation and settlement into marginal lands. This study investigates the spatial …

Towards a Polyalgorithm for Land Use and Land Cover Change Detection
Earth observation satellites (EOS) such as Landsat provide image datasets that can be immensely useful in numerous application domains. One way of analyzing satellite images for land use and land cover change (LULCC) is time series analysis (TSA). Several algorithms for time series analysis have …

Simulating Land Use Land Cover Change Using Data Mining and Machine Learning Algorithms
… are to: (1) review the breadth and depth of land use land cover (LUCC) issues that are being addressed by the land change science community by discussing how an existing model, Purdue's Land Transformation Model (LTM), has been used to better understand these very important issues; (2) …

Linking Streamflow Trends with Land Cover Change in a Southern US Water Tower
… (SA) region of the U.S. The forested uplands of the SA receive high amounts of rain and act as a "water tower" for the surrounding lowland area, both of which have experienced higher than average population growth and urban development. For the total of 127 USGS gages with continuous …

Land Cover Change During a Transition in Land Management at Valles Caldera 1989-2013
This study examines how land-use policies can play a role in manifesting physical landscape changes. In 2000, Congress enacted a unique experiment in public lands management by creating the Valles Caldera National Preserve and its governing body, the Valles Caldera Trust (VCT). The management …

Land-cover change within the peatlands along the Rocky Mountain Front, Montana: 1937-2009
Aerial photographs of nine peatlands along the Rocky Mountain Front, Montana, were analyzed in a GIS. The boundary of wetland extent was hand-digitized and the area within was classified into land-cover types including: total area, open fen, open water, woody vegetation, and …

Land Cover Change and the Breeding Bird Survey: Rates of Change in Relation to Roads
… transects. Based on BBS assumptions that land cover is the same adjacent to roads as it is away from roads the overall goal of this study is to determine if landscape changes have occurred on a broad scale over an expanded time period and if these landscape changes have been similar …

War and Agriculture: Three Decades of Agricultural Land Use and Land Cover Change in Iraq
… as estimated using satellite remote sensing, changed during and as a result of war and sanctions. The first study used MODIS NDVI data during OIF and the end of UN sanctions to study changes in cultivated area for Iraq as a whole and to identify spatial patterns. The results revealed …

Land Cover Change and its Impacts on a Flash Flood-Producing Rain Event in Eastern Kentucky
… a 35-county region that is a part of the Cumberland Plateau of the Appalachian Mountains. With mountaintop removal and associated land cover change (LCC) (primarily deforestation), it is hypothesized that there would be changes in various atmospheric boundary layer parameters and precipitation. …

Linking Local Knowledge and Satellite-Derived Land-Use/Land-Cover Change Information In Krabi Province, Thailand
… conversion in three coastal communities in Thailand. It presents a methodology that could potentially aid coastal communities in determining sustainable land use conversion approaches by considering the viewpoint of villagers. A remote sensing analysis of Landsat satellite images from 1989, 2001 …

The Impact of Climate Variability and Land Cover Change on Groundwater Resources in The Niger River Basin
… severe droughts and floods under a significant change of the land use and land cover (LULC) with increasing population over the years. The present study is to understand the hydrological dynamics of NRB by using a water balance modeling approach with the seasonal variation of precipitation and …

Land Use and Land Cover Change in the Crown of the Continent Ecosystem, Montana, USA from 1992-2011
In recent decades land use and land cover change (LULCC) has occurred throughout the Intermountain West. The Crown of the Continent Ecosystem (CCE) extends along the Rocky Mountains adjacent to the Canada-U.S. International border. In the U.S. portion of the CCE, located in northwestern Montana, …
