Land Use Changes and Pheasant Declines in Eastern South Dakota
Changes in pheasant (Phasianus colchicus) nesting habitat were investigated on Windsor Township, Brookings County, South Dakota. The population was censused, nesting densities determined, cover was mapped, and an interspersion index determined in 197 7 and 1978. Comparison to a similar study …

Land-Use Changes in Southwestern Guatemala: Assessment of their Effects and Sustainability
Land-use changes in the Pacific coastal plain of southwest Guatemala have accelerated in the past twenty years as native arable and pasture lands have been converted at an increasing rate to oil palm and banana plantations. This study of the changes during this period has been made by …

Between Fields and Cities: The Politics of Land Use Changes in Punjab, India
… thesis examines the urbanization of agricultural lands in the State of Punjab, looking for patterns that explain the type of development that is occurring while embedding these transformations in a larger political and economic context. The study will focus on both transportation infrastructure …

Spatio-Temporal Effects of Land Use Changes in A Savanna Wildlife Area of Kenya
Land use changes have been shown to have significant effects on wildlife species. Sixty three percent of the national Parks and Reserves in Kenya are located in the savannas. Because of the seasonality associated with savanna ecosystems, 75% of the wildlife species and numbers in Kenya occur in …

Estimates of global sources and sinks of carbon from land cover and land use changes
… of sources and sinks of carbon over the land surface is dominated by changes in land use such as deforestation, reforestation, and agricultural management. Despite, the importance of land-use change in dominating long-term net terrestrial fluxes of carbon, estimates of the annual flux are …

Are wetland plant communities in the Cape flora influenced by environmental and land-use changes?
… distribution and environmental condition of wetlands in South Africa. A 1987-1989 study investigated over one hundred wetlands to establish unique discernible features for grouping and classifying wetlands in the Cape Floristic Region. In the current study, a representative subset of the …

Sensitivity of Precipitation to Land-use Changes in a Regional Climate Model of West Africa
… for agricultural activities by causing changes in the background large-scale climate circulations which could lead to more precipitation overall in areas with water scarcity. Both observational and model studies have looked at irrigation impacts around the world, including West Africa. …

A finite element model to determine the effect of land-use changes on flood hydrographs
… conjunction with Galerkin's residual method, was used to mathematically route overland and channel flow. This numerical procedure was applied to the kinematic equations of one-dimensional transient flow in open channels. A one-dimensional finite element scheme was used to simulate overland flow …

Quantifying the impacts of climate and land use changes on the hydrological response of a monsoonal catchment
The effect of climate change and land use change on runoff generation and flooding has received great attention in many hydrological modelling studies. However, currently many hydrologists are still uncertain how much these two factors contribute to runoff generation, particularly in monsoon …

Projecting land use changes using parcel-level data : model development and application to Hunterdon County, New Jersey
… is to develop a parcel-based spatial land use change prediction model by coupling various machine learning and interpretation algorithms such as cellular automata (CA) and decision tree (DT). CA is a collection of cells that evolves through a number of discrete time steps according to …

A quantitative analysis of the impact of land use changes on floods in the Manafwa River Basin
… increase in flood events is also a response to land use changes; as more people use the land for agriculture and housing the percentage of less pervious and impervious area increases. Floods in the Manafwa watershed are often deadly and always an economic burden. In eastern Uganda there is …

An assessment of the impacts of land use changes on the Duthuni wetland stream using remote sensing, GIS and social surveying: a case study in Limpopo Province, South Africa
This is a case study research that focuses on the assessment of the impacts of land use changes on the Duthuni wetland ecosystem in Limpopo Province using geospatial techniques and Social Survey. SPOT 4 satellite images which covered the time frame between 1999, 2005 to 2012, were used. The unit of …

Application of GIS and Remote Sensing techniques to evaluate the impact of land cover and land use changes on the hydrology and water resources of Luvuvhu River Catchment in Limpopo Province, South Africa.
Luvuvhu River Catchment (LRC) exhibits diverse land use and land cover patterns that are influenced by seasonality and socio-cultural practices of the local communities. From 1950, the catchment has been undergoing land cover changes caused by expanding villages, new urban centres and clearing …
