In this study, land use change in the middle Taleghan watershed has been studied and analyzed. First, the land use map of Taleghan Mian watershed was prepared during the last thirty years in four years 1987, 1998, 2008 and 2017. Landsat satellite imagery was used to prepare land use map in four years. In this research, the hybrid classification method (combination of supervized and unsupervized...
Geospatial techniques can be used to assess the dynamic conditions of coastal land use and cover in order make informed decisions about future management strategies for sustainable development through a combination remote sensing data with field observations shoreline characteristics along coastlines worldwide. offer an invaluable method analyzing complex systems at multiple scales. The from Su...
In the context of economic renovation, Vietnam has transferred land-use rights form state and cooperative units under central planning to individual, community and other entities. Despite remarkable success in the lowland agriculture, the advancement in the uplands stays behind expectation. Agriculture land and forest, two basic components of the human ecosystem of the ethnic minority communiti...
Land use mapping is fundamental for assessment, managing and protection of natural resources of a region and the information on the existing land use is one of the prime pre-requisites for suggesting better use of terrain. Advances in satellite sensor and their analysis techniques are making remote sensing systems realistic and attractive for use in research and management of natural resources....
Agriculture began in the eastern Mediterranean Levantine Corridor about 11000 years ago toward the end of the Younger Dryas when aridity had diminished wild food resources. During the subsequent Climatic Optimum, agricultural villages spread rapidly but subsequent climatic changes on centennial to millennial scales resulted in striking oscillations in settlement, especially in marginal areas. N...

Extended abstract Introduction The present study was performed to investigate the effects of slope percentage and land use type on the produced sediment by an artificial rainfall simulator in Kakasharaf watershed, a branch of Karkhe watershed (Lorestan province). Methodology The rainfall simulator used in this research was designed and constructed by the Soil Conservation and...
The delivery and distribution of nutrients in coastal wetland ecosystems is much related to the land use. The spatial variations of TOC, TN, NH4+-N, NO3--N and TP and associated soil salinity with depth in 9 kinds land uses in coastal zone of the modern Yellow River Delta (YRD) was evaluated based on monitoring data in field from 2009 to 2015. The results showed that the average contents of soi...
