modeling and prediction of land use/cover changes is an essential need for planning sustainable use of land in country like iran with its high level of changes in land uses and land covers. this study aimed to analyze the capability of ca markov prediction model and landsat satellite images for land use/cover change detection within the framework of “iran at 1404 prospective” in esfarayen r...

Fresh water supply and its security encounter a high level of fluctuating variability under global climate changes. To address these concerns in catchment water management, a good understanding of land use/cover impacts on the hydrological cycle affecting water supply is crucial. The objective of this study is to define a model to investigate the impact of existing land use/cover on water yield...

Land use can be defined as the values that humans obtain from landscapes. What is it that people are actually doing on the landscape? Though remote sensing is often used for mapping land use and land cover over large areas, to actually map land use usually requires some careful human interpretation of the imagery or, better, surveying or interviewing people on the ground to identify their use o...

In this paper, urban growth of Bangalore region is analyzed and discussed by using multi-temporal and multi-spectral Landsat satellite images. Urban growth analysis helps in understanding the change detection of Bangalore region. The change detection is studied over a period of 39 years and the region of interest covers an area of 2182 km 2 . The main cause for urban growth is the increase in p...

Pressure on land resources is expected to increase as global population continues to climb and the world becomes more affluent, swelling the demand for food. Changing climate may exert additional pressures on natural lands as present-day productive regions may shift, or soil quality may degrade, and the recent rise in demand for biofuels increases competition with edible crops for arable land. ...

During Earth's history, species extinction has probably been caused by modifications of the physical environment after impacts such as meteorites or volcanic activity. On the contrary, the actual extinction of species is mainly a result of human activities, namely any form of land use that causes the conversion of vast areas to settlement, agriculture, and forestry, resulting in habitat destruc...

Geomorphometric features and land use/land cover are essential in the context of watershed prioritization for resources conservation and protection. Watersheds in tropical regions like the Philippines are under threat of degradation due to the combined effects of uncontrolled agricultural activities in the uplands and frequently increasing erosive precipitations brought about by climate change....
