Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael
Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael
International Journal of Geospatial and Environmental Research
Vegetation Land Cover/Land Use dynamics (VLC/LU) are the result of complex and compound interactions between the human (cultural, socioeconomic, and political) and the physical environment at different spatial scales. The present study assesses the spatial distribution of VLC/LU dynamics from 1987 to 2015 in the North-Eastern highlands of Tanzania using both qualitative (in-depth interviews and focus group discussions) and quantitative techniques (spatio-temporal analysis through GIS). The qualitative approach was used to elicit information on the main drivers of VLC/LU changes by land users as transitions occurred with time. The spatio-temporal analysis was used to assess the systematic vegetation land losses, …

Measuring And Modeling Of Urban Growth And Its Impacts On Vegetation And Species Habitats In Greater Orlando, Florida, Sunhui Sim, Victor Mesev
International Journal of Geospatial and Environmental Research
Urban growth is widely regarded as an important driver of environmental and social problems. It causes the loss of informal open space and wildlife habitats. Timely and accurate assessments of future urban growth scenarios and associated environmental impacts are crucial for urban planning, policy decision, and natural resource management. In this study, five distinct scenarios ("no constraints", "compact development", "transit-oriented development", "agriculture protection" and "environmental protection" scenarios) were tested on Greater Orlando, Florida, along with conservation objectives and projections for future land use/cover from development demands. The study examined the consequences of alternative scenarios of urban growth on potential habitat …
