During the last decades, the African continent has been experiencing population dynamics at rates which are considered to be among the strongest in human history. While Africa's population increased rapidly to currently 1.1 billion of people, it is expected to double until the year 2050 [1]. This human population increase goes in line with a strong urban growth, and urbanization rates of some African...
This paper examines whether eastern Tigray is still in a phase of land degradation or if a trend of landscape greening has started. Hitherto, the land cover in five representative Tigray villages was mapped for three different periods: 1965, 1994, and 2007. These maps were based on the interpretation of aerial photographs and high‐resolution satellite imagery in combination with field validation....
Land use and land cover change (LUCC) is an important factor of global environmental change. LUCC model is the focus of land change research. LUCC of the study area in the next 13 years is predicted based on CLUE-S model. Two prediction scenarios were used which are with or without considering “Liaoning Coastal Economy Development Plan”. The results showed that the construction land increased dramatically...
Regional land use change has been and will continue to be one of the hugest human impacts on the environment. Based on eight remotely sensed images of Guiyang city from 1973 to 2001, this paper studies the effect of urban sprawl on the land use and land cover of Guiyang in recent three decades. The process and characteristics of urban expansion and the surrounding land use change were analyzed. Besides,...
Urbanization, the conversion of other types of land to uses associated with growth of populations and economy, is a main type of land use and land cover change in human history. In recent 30 years, urban growth has been speeded up, and extreme stress to the environment has occurred in China. Based on the Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) stable nighttime...
Monitoring landscape change is critical to better understand urbanization impacts on ecosystems. Remote sensing and geo-referenced socio-economic data provide powerful tools for documenting changes in the landscape and developing strategies to minimize the effects of urban development on natural habitats. The interpretation and analysis of urban land cover change from remotely sensed images however...
