Agricultural Water

Agricultural water consumption corresponds to 85% of global freshwater and is projected to double in 2050. The global water footprint of crop production in the period 1996–2005 was estimated to 7404 Gm3yr−1. Crops especially wheat (1087 Gm3yr−1), rice (992 Gm3yr−1) and maize (770 Gm3yr−1) require significantly amounts of water for production. In the coming years, crop production will increase in order to meet the growing demand of food, the new diet preferences and the shift from fossil energy toward bioenergy. Few new lands will be available so all production must come from the current natural resource base, requiring an intensification by increasing land and water use. Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
