. introduction if environmental hazards, including those with atmospheric origin and terrestrial origin cause economic and human life losses for human societies, they would be considered as disasters. terrestrial hazards, which mostly occur as catastrophic, may have economic and human life damages when they occur in a small scale but with high intensity. mass movements are among the most import...

in the case of iran with arid and semiarid climate and lack of freshwater, pay attention to water quality and its effective factors is necessary. karkheh watershed is more than 5 million hectares in area and with biggest soil dam in asia, which has widespread land use changes in last decades. the most important factors of water volume and water resources reduction are aridity and improper land ...

extended abstract 1. introduction the investigation of land cover and land use changes has been important since ancient eras and these changes mainly occur in two ways: the first types of these changes take place by the means of natural factors such as erosion, tectonic forces and floods and the second types take place by human factors. in recent years in many parts of the world, human oriented...

this research has been carried out with the aim of the determination of the land-use changes of the forests in the protected area of arasbaran. the determination of the changing points and the factors influencing these changes by the use of gis and remote sensing are the main aims of this research. accordingly, the satellite pictures pertaining to the years 1987 and 2005 along with other necess...

large scale land use/cover changes and habitat fragmentation is a major factor in the distribution and functioning of ecosystems. for analysis the relationship between land use changes and their impacts on biodiversity, land cover and land use information is needed at different scales. the main goal of this study was to quantify the land use/ cover changes in arasbaran biosphere reserve, northw...

in the recent years, human activities have led to changes in land use and land cover, consequently, these changes lead to the structure and function of ecosystems. spatial-temporal change detection of land use is important to understand the relationships and interactions between human and natural resources and to make appropriate decisions due to changes in land use and land cover occurs in bro...

Intraurban land-use change and factors affecting it are critical subjects in land-use planning. If unplanned, such changes can reduce the quality of life and spatial justice and ultimately lead to urban unsustainability. This paper aims to identify factors influencing unsustainable land-use change and analyze the intensity of such changes based on those factors. The artificial neural network an...
