1 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Water statistics and accounts in the Republic of Moldova Dr. Jana Tafi & WDC team Water Data Centre project/ Ministry of Ecology and Natural Resources of the Republic of Moldova)

2 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 National demand for water statistics Moldova has signed the International Conventions and agreements related to water resources and has to fulfill its obligations: Convention on protection trans boundaries rivers and lakes (Helsinki, 1992), Black Sea convention on the environment (1994), Sofia convention on the Danube River (1994), RAMSAR (1971). The Parliament and the Government of Moldova has adopted Framework of national policy in the water resources domain (N 325-XV din )

3 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Water statistics Monitoring & surveys for quantitative and qualitative indicators of the availability, state and use of water resources quantitative and qualitative indicators of the availability, state and use of water resources Water as resource for population & agriculture Pressure on water resource ( in Moldova households pollution has replaced industrial) Supports sustainable development in country

4 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Methodology used for water accounts case study in Moldova Physical accounts for water resource in raw quantities using SEEA 2 projects: : initial project by the statistical institute (DASS) & IFEN (French Environment Institute) Since October 2001: lead by Ministry of Ecology (with IFEN & Beture Cerec)

9 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Primary Data Sources for Resource Accounts

10 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Survey about water consumption run by Apele Moldovei the National Water Agency Annual mandatory questionnaire sent to economic agents Data give view about abstraction, supply, use, discharge of water in m3 & emissions of pollutants in tones From 1983 the survey was exhaustive Presently, new approach by Apele Moldovei: Selective survey + Water accounts

11 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 HBS used as a basic survey to study ecological needs: one page added to the main Questionnaire 1: 1999 survey First ecological survey to define current ecological problems: actual ecological problems of the population of the country, actual ecological problems of the population of the country, populations attitude to problems, populations attitude to problems, level of environment pollution directly caused by households level of environment pollution directly caused by households Including a number of questions on water issues Used type of water resources Used type of water resources Volume consumed water Volume consumed water Quality of drinking water Quality of drinking water Influence of water to human health status. Influence of water to human health status. In December 1999, 520households (families) were enrolled with a total number of 1,4 thousand persons, 63% of them in rural areas In December 1999, 520households (families) were enrolled with a total number of 1,4 thousand persons, 63% of them in rural areas

12 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Second survey concentrated only on water problems and other related issues: state, pollution, consumption, water supply and water management. To analyze the current trends, some questions from the first survey were included in the second survey: access to water supply, water consumption, quality of drinking water in wells and springs, influence of state of water on health status On April 2001, representative sample of 521 households, involving 1404 persons, from urban and rural areas HBS used as a basic survey to study ecological needs: one page added to the main Questionnaire 2: 2001 survey

26 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005 Implementing water accounts 1. Physical accounts require validation by policy makers : Water Agency, Ministry of Economy, Ministry of Environment; 2. Possibility of making detailed physical water accounts has to be checked (lack of data on consumption by farmers, small business, rural households…) 3. Difficulties for statistical institute to maintain such type of accounts because physical water accounts are asking for combination skills of statisticians & ecologist, hydrologist, chemistries 4. Implementation of water accounts demanding multi-institutional involvement
