Human footprint models allow visualization of human spatial pressure across the globe. Up until now, Antarctica has been omitted from global footprint models, due possibly to the lack of a permanent human population and poor accessibility to necessary datasets. Yet Antarctic ecosystems face increasing cumulative impacts from the expanding tourism industry and national Antarctic operator activit...

Environmental or 'ecological' footprints have been widely used in recent years as indicators of resource consumption and waste absorption presented in terms of biologically productive land area [in global hectares (gha)] required per capita with prevailing technology. In contrast, 'carbon footprints' are the amount of carbon (or carbon dioxide equivalent) emissions for such activities in units ...

Article history: Received 26 September 2007 Received in revised form 2 June 2008 Accepted 19 June 2008 Available online 8 August 2008 The water footprint concept introduced in 2002 is an analogue of the ecological footprint concept originating from the 1990s. Whereas the ecological footprint (EF) denotes the bioproductive area (hectares) needed to sustain a population, the water footprint (WF) ...

Pollutants of Carbon flow virtually by streaming the Goods and services among the countries. Due to the Carbon Footprint (CFP) in economical divisions as well as subdivisions in Iran, the main objective of this paper is to specify the effects of Carbon footprint on import and export of various sections in the framework of Computable General Equilibrium Model. It’s used the social accounting mat...

Decisions can be taken to increase energy efficiency and to mitigate the emissions to the environment by examining the energy audit and greenhouse gas (GHG) emissions footprint of crop production in different ways and in different regions, with comparable principles. In this study, energy consumption and energy indices of tomatoes production in four regions of Iran including East Azerbaijan...

the ecological footprint is a useful tool that we can use it to inform the public about the pressure on ecology and the environment. also, by measuring it, policymakers can design and implement the necessary programs to help reduce that pressure. in order to measure the potential impact of future activities and policies of development programs on the environment, it is necessary to study the sh...

It is often argued that 3D inversion of entire airborne electromagnetic (AEM) surveys is impractical, and that 1D methods provide the only viable option for quantitative interpretation. However, real geological formations are 3D by nature and 3D inversion is required to produce accurate images of the subsurface. To that end, we show that it is practical to invert entireAEMsurveys to3Dconductivi...
