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 …

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 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, …

Application of Remote Sensing and GIS in Monitoring Land Use and Land Cover Change in the Nandoni Dam Basin
Land use activities and land cover (LULC) changes have been widely acknowledged as the main drivers of environmental change at all spatial-temporal scales in some South African dam basins. The consequence of these land use activities causes encroachments, land cover changes, sediment deposits, …

Dialectics of Rural Change: A Political Economy of Livelihoods and Land Use and Land Cover Change in Rural Western Kenya
… examines the political economy of livelihoods and land use and land cover change in rural western Kenya during a period of economic change. The research findings are presented in three stand-alone papers. The first paper examines the initiatives and policies implemented by the state in the past …

Analysis of land use and land cover change and its impact on soil erosion in Nzhelele Valley, Limpopo Province, South Africa
Globally, the rate of land use and land cover changes has affeceted the magnitude of soil eroion. Strategies to combat soil erosion can give assistance as solutions to provide food security in many agricultural areas. Although some changes are caused by natural factors, anthropogenic factors and an …

Detecting and predicting land use and land cover change in the cross-sanaga-bioko coastal forest region for sustainable forest management
This study assesses forest, agriculture and built-up areas change in the Cross-Sanaka-Bioko (CSB) region from 2000 to 2021, aiming to provide reliable data for sustainable forest management practices. This analysis will be accomplished with the aid of GIS tools (Google Earth Engine and ArcGIS Pro) …

Optical and radar remote sensing of land use and land cover change in the tropics: An assessment of deforestation and secondary vegetation
<p>Quantification of the direct impact of land use in the tropics on net biotic carbon flux requires estimates of rates of deforestation, pre- and post-disturbance biomass, and fate of the cleared land. Synoptic observations of the extent, persistence, rates of secondary succession, and structure …

Landscape patterns and patch dynamics in Hamilton county over a forty year period: applicability to the conservation of the eastern box turtle
… development is the fastest growing form of land use in the southeastern US and the primary driver of habitat and biodiversity loss. Species with long generation times such as the eastern box turtle (Terrapene carolina carolina) can persist in an urbanizing environment but have higher …

Assessing agricultural expansion in upper Lunsemfwa river catchment: a case study of the upper Lunsemfwa river catchment, central province, Zambia.
Understanding dynamics occurring in land utilization and land cover is essential for analysing and assessing long-term transformations. These transformations in land cover primarily result from deforestation, which involves the conversion of forests into other land cover types such as agricultural …

Evaluating the influence of establishing pine forests and switchgrass fields on local and global climate
… extensively altered terrestrial surfaces through land-use and land-cover change. This change has resulted in increased food, fiber, fuel, and wood that is provisioned by ecosystems to support the human population. Unfortunately, the change has also altered climate through carbon emissions and …
