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...
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...
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...
Natural ecosystems provide services to agriculture such as pest control, soil nutrients, and key microbial components. These services and others in turn provide essential elements that fuel biomass productivity. Responsible agricultural management and conservation of natural habitats can enhance these ecosystem services. Vineyards are currently driving land-use changes in many Mediterranean eco...
human activities induced changes in land cover/use have extensive impacts on the landscape. in recent years, these changes had an increasingly growth due to irrational use of the natural resources in iran. hence, considering the negative effects of the inappropriate use of land and land-use change, understanding of the landscape changes over time is necessary to planning and implementation of s...
Land use change is one of the most important factors of global environmental change. So, understanding and predicting the causes, processes and consequences of land use and land cover has become a major challenge. The Remote Sensing and Geographic Information System (GIS) technologies can be used effectively to detect and quantify of land use changes and its effects on the environment. The pur...
agricultural land conversion (alc) has been introduced as one of the most important factorsaffecting ecosystem. this type of conversion has led to several challenges in agricultural development andhuman life. monitoring alc plays a crucial role when dealing with such challenges. the main objective of thisstudywas to monitor the trend ofalc in theqazvin province located in northwest iran from 19...
Prangos ferulacea (L.) Lindl is a perennial plant that besides fodder and medicinal values the plant can help to control soil erosion. There is little knowledge about the effect of climate change on the Prangos genus especially P. ferulacea. In this study, we used ensemble modeling based on five species distribution models to predict the potential effects of climate change on the future geograp...
providing of landing use maps and detecting of land capacity are required to manage of natural resources and environment and planning of land use. on the other hand, it is necessary to detect of the human deriving forces affecting land use change. in this research, we selected seyed mohaleh and drasara villages in tonekabon city. first, were provided the land use maps in 1987 and 2008 by using ...
purpose: one of the major problems in the agriculture field is the land use change that has been growing recently and disturbing the balance of agricultural products in long term. there are many factors that affect farmers' willingness to change the use of land. in this regard, the main objective of this study is to identify factors which affect the agricultural land use change in rural areas i...
