In particular, site monitoring takes place through the following levels of analysis: > mapping production sites in areas with potential “water scarcity” sit uations, in which the average value of renewable water resources per person is lower than the reference set by FAO (the mapping is carried out with the Global Water Tool of the World Business Council for Sus tainable Development); > identification of “critical” produc tion sites, i.e. those in “Water Scar city Areas” with withdrawals; > more efficient management of wa ter, also aimed at maximizing the supply from wastewater and sea water; > monitoring of sites’ climate and vegetation data.
