We present a new calculation of Australia’s ecological footprint. Modifications have been made to the concept as originally proposed, in response to its perceived shortcomings: rather than characterising the consumption of the Australian population in terms of appropriated ‘bioproduction’ at world-average productivity, a regional, disturbance-based approach is taken, including actual Australian...

The western “panhandle” region of Florida experienced greater development in the years 2000-2010 than the previous 40 years and greater than nearly all other parts of the United States. One reason is the fact that much of the coastal land in the peninsula of Florida is already developed whereas much of the Panhandle is empty. Another reason is the fact that increasing temperatures and less seve...

China is in the process of rapid urbanization, and wise land use is critical to the longterm sustainability of Chinese cities. Promotion of a compact city is typically believed to be a helpful for sustainable land use management. However, given the fact that Chinese cities are characterized by high population densities, the applicability of a more compact solution to expanding cities in China r...

The significance of land cover as an environmental variable has made land use change an important subject in global environmental change and sustainable development. Modeling land use change has attracted considerable attention. Currently, empirical estimation models using statistical techniques are one of mostly used spatial models to simulate land use pattern and its changes. Empirical estima...

A refined land cover classification for the arid Phoenix (Arizona, USA) metropolitan area and some simple modifications to the surface energetics were introduced in the fifth-generation PSU/NCAR mesoscale meteorological model MM5. The single urban category in the existing 24-category United States Geological Survey (USGS) land cover classification used in MM5 was divided into three classes to a...

The increasing amount of free and open remote sensing data suggests that a number of multitemporal land use and built-up land datasets derived from remotely sensed imagery will be made available soon. However, little research has been done regarding the approaches to evaluate spatiotemporal uncertainty of such products. Employing publicly available cadastral data with information on constructio...

Background: Physical activity, whether in water or on land, can improve motor disorders in the elderly. However, the more effective type of exercise remains inconspicuous. Aim: To compare the effects of aquatic and land-based exercises on the bio-motor abilities of elderly men. Method: This clinical trial was performed on 60 elderly men visiting Imamat and Daneshamuz health centers in Mashhad, ...

The ERS Interferometric Quick Look processor developed by ESA has made it possible to examine the interferometric coherence of ERS data for land-use applications on a world wide scale. Many successful interferometric studies have been focussed on relatively small regions of terrain. This is partly because of the localised nature of some of the areas of interest but also because of the relativel...

The rapid expansion of urban construction land has become the major characteristic of urban land-use change in China today. Meanwhile, the rapid urbanization process has led to the great changes of urban landscape in China, and it also has had certain impacts on environmental factors such as climate, soil, hydrology, biodiversity, etc., then it has made the overall ecological environment deteri...

Much of the agricultural land in the Central Hills area of the Sichuan Basin is at risk from soil erosion by water. An investigation of rates and patterns of soil erosion on agricultural land near Yanting was undertaken using the caesium-137 technique. Erosion of the upper parts of sloping fields was found to be severe, with rates of the order of 20 to 50 t ha" year". However, infield depositio...
