While Canada ranks second in the world in terms of national land area, its most productive arable land is limited in extent. These lands are also under pressure due to rapid urbanization, especially in the high growth areas of southern Ontario, the CalgaryEdmonton corridor and the lower Fraser River valley of British Columbia. Currently, a program is underway in the Earth Sciences Sector of Nat...

Taking the Landsat TM and ASTER images of Hanshiqiao wetland nature reserve in 1988, 1996 and 2004 as data source, based on the images interpretation by supervised classification, the land use changes during the period 1988 to 2004 were analyzed through land use dynamic degree. And then the driving forces of land use changes were analyzed based on natural and artificial factors. The results ind...

Earth’s land cover has been extensively transformed over time due to both human activities and natural causes. Previous global studies have focused on developing spatial and temporal patterns of dominant human land-use activities (e.g., cropland, pastureland, urban land, wood harvest). Process-based modeling studies adopt different strategies to estimate the changes in land cover by using these...

Under the premise that land administration is one of the necessary components of sustainable development and better land management, this article reviews how progressive titling could foster new land administration procedures and associated information systems. This review is based on the objectives of progressive titling as they are developed or currently implemented in various regions in the ...

Conversion of agricultural land into built-up is a regional economic development mechanism, where to increase Gross Domestic Product can be done by allocating the widest possible pattern space designation "industry, trade and settlement", implication conversion land. (rice fields) increases rice production facilities decrease so that food fulfillment constrained, in other words there off use pa...

land use changes are one of the important consequences of urban spatial extent. regarding the role of green space as one of important land use classes in urban ecosystems, the investigations of its changes seem to be crucial. in this study, to estimate the changes of green space, the ndvi index was applied to tm and irs images of 1990 and 2006 and green space maps of district 1 of tehran munici...
