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) Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
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 2003-2010 (N 325-XV din 18.07.2003) National demand for water statistics 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, stateand 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 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: 1998-2000: initial project by the statistical institute (DASS) & IFEN (French Environment Institute) Since October 2001: lead by Ministry of Ecology (with IFEN & Beture Cerec) Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
The set of environmental and economic accounts for water Accounts of Main Linkages to Monitoring & Surveys National Accounts the domain The accounts presented above are a gateway between the domain of economic statistics (the National Accounts and their input-output tables (I-O Tables) and the domain of environmental and resource monitoring and assessment (generally presented by means of indicators). Assets Accounts Resource accounts Supply & Use accounts I-O Tables, NAMEA Uses Emission accounts I-O Tables, NAMEA Emissions Quality accounts Production & Income Expenditure accounts Accounts Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Water accounts cover From the economic perspective, : • Resource usage per sector • Polluting discharges per sector (emissions from sectors) • Expenditure for resource protection and operation. From media point of view : • The resource system (hydrological system) • Water quality (rivers and aquifers, at least) • Discharge of pollutants to the media. Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Main data sources • Meteo data (Hydrometeo service) • Hydrological data (Hydrometeo service) • Groundwater survey data (“AgeoM” & Ministry of Health) • Surface water survey data (Ministry of Health) • Inventory data: lakes, dams, wells, WWTP ( State Ecological Inspectorate, Apele Moldovei, AgeoM” & Ministry of Health ) • Surveys & consulting companies & IFEN ( Beture-Cerec, TAHAL) • Annual Survey by” Apele Moldovei”, the National Water Agency (reports from companies, communal services and irrigation supply) • Household Budget Survey & Special household surveys related environmental needs (NBS - Statistical Institute) • Annual technical & economical report by Communal services (NBS & Water Company) Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Water resource : the sources of data depend on the natural conditions and on the monitoring systems • Meteorology (precipitation, but also basis of calculation of potential evapotranspiration) • Institute of agronomy : Water stock of the soils and vegetation coverage (for the calculation of actual evapotranspiration). • Hydrology/Hydrogeology institute, flow in the water-courses and groundwater table level, • Various services : reserves in dams, cartography, etc. Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Primary Data Sources for Resource Accounts 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 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
First ecological survey to define current ecological problems: actual ecological problems of the population of the country, population’s attitude to problems, level of environment pollution directly caused by households Including a number of questions on water issues Used type of water resources Volume consumed water Quality of drinking water 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 HBS used as a basic survey to study ecological needs:one page added to the main Questionnaire1: 1999 survey 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 Questionnaire2: 2001 survey 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 Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005

WATER RESOURCE AND USE ACCOUNTS • Resource Availability Indicators • e.g. : Groundwater replenishment rate, Natural inflows, Annual available resource (net…) • Resource Use Indicators • e.g. Intensity of abstraction by sectors, Total consumption of water, Returns of waste water • Resource Depletion Indicators • e.g. Evapo-transpiration inducted by irrigation, Depletion of groundwater (net accumulation…) Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Policy making indicator • Water balance is essential for the optimization of water management and use • Renewable water resource • Non-renewable water resource • Quality of water resource is determined by natural factors and by human activities • Population connected to wastewater treatment • Industrial & agriculture activities • Urbanization process impact Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Implementing water accounts • Physical accounts require validation by policy makers : Water Agency, Ministry of Economy, Ministry of Environment; • Possibility of making detailed physical water accounts has to be checked (lack of data on consumption by farmers, small business, rural households…) • Difficulties for statistical institute to maintain such type of accounts because physical water accounts are asking for combination skills of statisticians & ecologist, hydrologist, chemistries • Implementation of water accounts demanding multi-institutional involvement Dr. Jana Tafi & WDC team International Work Session on Water Statistics Vienna, Austria, 20 June – 22 June 2005
Water resources quality indices • the average annual concentration of pollutant in the locality, on the spot, in the river basin, mg/l • media-variant, which corresponds to the probability rate of 50%, in % • recurrence of pollutant content in the water higher than SCL (Standard Concentration Limit), 10SCL, 30SCL, 50SCL, 100SCL, % • enabling to characterize the state of water for the purposes of compliance with the current norms and standards.
