  Gully erosion is one of the geomophological phenomenon that causes numerous losses to farmland, rangeland, roads, and increased sediment rate. Recognition of the causes and modeling gully erosion has an important role in watershed management, which aids in preventing the destruction of lands in sustainable development. In this research, a gully erosion map was prepared with the use of airp...

Earth surface temperature is an important indicator in the study of energy equilibrium models at the ground level on a regional and global scale. Due to the limitation of meteorological stations, remote sensing can be an appropriate alternative to the Earth's surface temperature. The main objective of this study is to monitor the surface temperature and its relationship with land use, which is ...

Effective soil conservation requires a framework modelling that can evaluate erosion for different land-use scenarios. The USLE model was used to predict the reaction of appropriate land-cover/land-use scenarios in reducing sediment yield at the upland watershed of Yamchi Dam (474 km2), West Ardabil Province, Iran. Beside existing scenario, seven other land-use management scenarios were determi...

Predicting land use change is an indispensable aspect in identifying the best development and management of land resources and their potential. This study used certified land-use maps of 1997, 2006, and 2015 combined with ancillary data such as road networks, water bodies and slopes, obtained from the Department of Agriculture and the Department of Surveying and Mapping in Malaysia, respectivel...

One of the most important problems facing desert areas today is the growing trend of desertification and land use change. Land use is a special use of man from the earth. These uses are changing over time and these changes lead to increased land degradation and ecosystem destruction, especially in arid and semi-arid regions. Accordingly, in this research, the trend of land use change in the eas...

1. introduction the meaning of sustainability is an effort to reach the best results in human and environmental programs which are considered to be for present and future. zayandeh-rud is the most important and vital river in esfahan area which is used in agriculture, industry, providing drinking water and all other economic sectors. this river is originated from the zagros mountains – zardkooh...

Remote sensing technology is one of the most efficient and innovative technologies for agricultural land use/cover mapping. In this regard, the object-based Image Analysis (OBIA) is known as a new method of satellite image processing which integrates spatial and spectral information for satellite image process. This approach make use of spectral, environmental, physical and geometrical characte...

the term degradation is used to specify the status of the environment. it is often associated with ‘improper use’. ‘use’ also implies environmental aspects other than physical ones and implies that the more intensive the use, the more susceptible the environment is to degradation, particularly if proper care for the environment is lacking. the question is, and has always been, how to map someth...

investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...
