DOWNLOAD EBOOKThis report is the presentation of the methodology applied in Italy to spatially disaggregate the computation of the level of water stress from the national to the subnational scale (SDG indicator 6.4.2). Compared to the national assessment, which results in a low level of water stress in the country, the spatial disaggregation of the indicator by the hydrological unit highlighted the presence of basins affected by water stress exceeding 60 per cent (district of the Po river basin). The analysis was performed considering the long-term average of the available fresh water resources calculated on different reference periods (1951-2020, 1961-90, 1991-2020), and this put in evidence the impact of climate change on the level of water stress. This report is part of the series SDG 6.4 MONITORING SUSTAINABLE USE OF WATER RESOURCES PAPERS that collects all the achievements on SDG 6.4. The study was implemented by the Italian Institute for Environmental Protection and Research (ISPRA), responsible for the model and data used to assess the total renewable freshwater resources, and the Italian National Institute of Statistics (ISTAT), which has provided the methodology and the official statistics related to water withdrawals by economic sector (Agriculture, Services, and Industry). The study is the outcome of an agreement between FAO and ISPRA under the Integrated Monitoring Initiative for SDG 6 (IMI-SDG6), designed to produce a map of Italy showing the SDG indicator 6.4.2 “Level of water stress: freshwater withdrawal as a proportion of available freshwater resources” disaggregated at river basin district level.
