    En pocas palabras, la escasez de agua tiene lugar cuando la demanda supera el suministro de agua dulce en un área determinada. Escasez de agua = un exceso de demanda de agua para el suministro disponible Esta situación aparece como consecuencia de una elevada demanda agregada por parte de todos los sectores que consumen agua respecto al suministro disponible, bajo las condiciones de infraestructuras y las disposiciones institucionales existentes.

    The AgriTech Toolbox enables researchers and policymakers to examine how alternative agricultural practices and technologies can impact farm yields, food prices, natural resource use, hunger, malnutrition, land use and global trade in 2050, when climate change impacts may be severe. As a result, it can inform the right mix of policies and investments needed to tackle the challenges agriculture faces in the coming decades. The AgriTech toolbox models the impacts of 10 technologies on farm yields, food prices, natural resource use, hunger, malnutrition, land use and global trade.

    Private property accounts for much of the planet's arable land, and most of this has been cleared for agricultural production. Agricultural areas retain only fragments of their original vegetation and this has been detrimental to many native plant and animal species. Habitat restoration and revegetation may be able to reconnect and enlarge existing remnant areas in agricultural landscapes and, thereby, enhance native plant and animal communities. However, conservation initiatives will be successful only if landowners actively participate in restoration actions.

    Numerous land-cover change detection techniques have been developed with varying opinions about their appropriateness and success. Decisions on the selection of the most suitable change detection method is often influenced by the study region landscape complexity and the type of data used for analysis. For different climatic areas, the method that suits best the seasonal land-cover change identification remains uncertain.

    Pricing greenhouse gas emissions is a burgeoning and possibly lucrative financial means for climate change mitigation. Emissions pricing is being used to fund emissions-abatement technologies and to modify land management to improve carbon sequestration and retention. Here we discuss the principal land-management options under existing and realistic future emissions-price legislation in Australia, and examine them with respect to their anticipated direct and indirect effects on biodiversity.

    Chemical and sediment losses from agricultural lands are threatening coastal marine and aquatic ecosystems in many parts of the world. This is an acute problem in Australia, where the condition of Great Barrier Reef (GBR) ecosystems is threatened by increased pollutant loads from agricultural lands, and Governments have enacted policies to reduce pollutant exports. These policies raise the question of how to identify changes in land management that will effectively reduce exports.
