Land Use Information is a key dataset required to enable an understanding of the changing nature of our landscapes and the associated influences on natural resources and regional communities. The Victorian Land Use Information System (VLUIS) data product has been created within the State Government of Victoria to support land use assessments. The project began in 2007 using stakeholder engageme...
There are 1.9 hectares of productive land available for each of the 6 billion people living in the world at present. In our industrialised Western society it is sometimes hard to realise quite how fundamental land is to our life on earth. The top six inches of land, which is soil, has to provide us with all our food. The land has to absorb much of our waste and is the catchment and filter for o...
land use mapping using fuzzy classification: case study in three catchment areas in hamedan province
land cover mapping is important for many planning and management activities. today, satellite images and remote sensing techniques are extensively used in all sectors including agriculture and natural resources because they provide updated data and high analyzing abilities. in this study, in order to produce land cover map for the northern part of hamedan province , digital satellite data irsp6...

East African forests have been largely converted to agriculture. The remaining forests hold many endangered species but are threatened by the heavy local demand for fuelwood. Here we evaluate fallow land in western Uganda as an alternate fuel source to diverse forests. We quantify the regeneration process on fallows, calculate tree biomass increases, and measure grass and woody herb biomass ove...

This article addresses one peripheral issue that cries out for such consideration: the international resource privilege (IRP). After explaining briefly what the IRP involves I argue that it is unethical and should not be supported in international law. My argument is based ...
Land use and climate change can accelerate the depletion of freshwater resources that support humans and ecosystem services on a global scale. Here, we briefly review studies from around the world, and highlight those in this special issue. We identify stages that characterize increasing interaction between land use and climate change. During the first stage, hydrologic modifications and the bu...
L and-use change in the United States represents an enormous uncontrolled experiment in the ways habitat changes influence plants and animals. When cities were built, land was plowed, or forests were cut, the effects on our native biota were not considered. Of course, humans have influenced the flora and fauna of North America over the ages. Native Americans established settlements, practiced a...
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 ...
