  1. UN Water data problems • Total Water withdrawal – Tunisia 2001 UNSD = 2.14 km3/yr AQUASTAT = 2.85 km3/yr • Total population – Tunisia 2001 World Bank = 9 673 600 inhabitants UNFPA = 9 539 000 inhabitants • Official water withdrawal per capita has 4 interpretations [221.2]; [224.3]; [294.6]; [298.7] (in m3/(yr cap)) FWMS allows agreement -> All report 294.6 m3/(yr cap)) - or - FWMS allows disagreement -> 294.6 ± 70 m3/(yr cap)

  2. Data provider - modus operandi AQUASTAT validates & updates new withdrawal values AQUASTAT re-validate & updates new withdrawal values Data may change or not Review files/emails containing past harmonization issues, and country methodology notes Download latest population data (from another data provider) Update latest population data into AQUASTAT Compare conflicting values

  3. Data provider - improved system AQUASTAT or partners provides new withdrawal or population values Review differences in interface containing past harmonization decisions All partners re-validate & update new withdrawal Values, with full understanding of all conflicting values Data may change or not
