Land conversion

Hvunan activities have already significantly converted or modified the natural land cover of half of Earth s terrestrial surface. Virtually no region remains untouched by human impacts of some kind. The major land conversions we have accomplished over the past 10,000 years or so include (1) land clearing, mostly through deforestation and...

Intrasystem processes and their effects on solute transport can be evaluated by measuring solution chemistry at different stages of a hydrologic pathway. Studies of nitrogen transformations along hydrologic pathways in Amazon catchments have been conducted by McClain et al. (1994) and Brandes et al. (1996). Only Williams et al. (1997b) have addressed the effects of land conversion on... 

Land Conversion of natural and agricultural land or greenfields to built environment should be minimised and land must be recycled in the sense that disturbed land such as former industrial zones (brownfields) and used or blighted urban areas (greyfields) need to be restored to productive use. Land use is also connected to patterns of development that either create efficient urban forms at one extreme or urban sprawl at the other. Urban sprawl leads to overdependence on the automobile...

The increasing support for biofuel production over the last years in both developed and developing countries has been taking shape under a variety of policy tools aiming at several objectives from increasing biomass, to land conversion, redistribution issues, fuel consumption, fuel and food prices, to cite a few. Subsidies, under various facets across countries, are the most commonly-used measure in support of biofuels...
