abstract decadal changes in land use/land cover for balachaur watershed in nawanshahar district, punjab, india were studied using black and white aerial photographs for march 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (fcc) of irs-1d liss-iii on 1:50,000 scale for march 2002, september 2002, and may 2003 and interpreted visually to prepare land use/land ...
Land use change is an essential determinant factor in hydrological processes and it affects many of them. Simulation of land use changes, rise in residential and agricultural area and its effects are among the most important issues related to the watershed management. The objective of this research is land use change detection in the past and simulation of future land use using CLUE-s Model. At...
abstract:â green spaces, especially urban gardens have been a subject of study in many countries for a long time, but the subject has been mostly overlooked in iran. therefore, this study tries to analyze the changes in land use and how we can protect green spaces (gardens) in jahrom in line with sustainable development in 1996-2006. the data in this study were collected through local investiga...
Models are used in a variety of fields, including land change science, to better understand the dynamics of systems, to develop hypotheses that can be tested empirically, and to make predictions and/or evaluate scenarios for use in assessment activities. Modeling is an important component of each of the three foci outlined in the science plan of the Land-use and -cover change (LUCC) project (Tu...
land-use change affects a number natural processes such as soil erosion, sedimentation, flooding and destruction of soil physical and chemical properties. this change of ecosystem causes the degradation of soil quality which eventually leads to a severe decrease in soil fertility. therefore, various aspects of land-use change should be taken into account in national major decision makings. this...
Urban land use change is one of the key issues in urban planning that has been addressed by researchers in many different aspects, especially from the perspective of space. But the point that has been overlooked in various studies is that the analysis of different aspects of land use change is not limited to classical and spatial factors, and because of the various interest of land use change, ...
Analysis of land use change in Nazlou district of Urmia in the 2005-2018 time series Abstract Population growth, increased prosperity, the spread of technology, and the improper use of land have in recent decades imposed many changes on land. Nazlou district in Urmia city has been exposed to many changes due to its favorable natural conditions, location in the development paths of Urmia-Cir an...
The land use change is one of the major challenges of the human communities in this century and even more its impacts are than the climate change phenomenon. Land use change influences run-off as well as the other hydrologic factors such as interception, infiltration and the flood intensity. This study is aimed to investigate the impact of last 30 years of land use changes on hydrological behav...
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...
Land use change is driven by interaction in space and time between humans and the environment that can be captured by computer simulation models (Veldkamp and Verburg, 2004). In the last few decades, land use change models have played an important role in understanding the causes, mechanisms and consequences of land use dynamics. SLEUTH is an open source cellular automata based land use change ...
