3. WHO-UNICEF Joint Monitoring Program (JMP)  Responsible for monitoring progress towards the MDG 7 Target 7C Global accountability and advocacy Global accountability and advocacy  Biennial updates of coverage estimates Water supply, sanitation, urban, rural, total, household connections, by country, region and global Water supply, sanitation, urban, rural, total, household connections, by country, region and global

4. MDG target + Indicators MDG 7 Target 7C:  Halve, by 2015, the proportion of people without sustainable access to safe drinking water and basic sanitation Indicators:  Proportion of population that uses an improved drinking water source, urban and rural  Proportion of population that uses an improved sanitation facility, urban and rural

5. MDG definitions of improved/unimproved sources of drinking water and sanitation facilities Improved water supply Piped into dwelling, plot or yard Public tap/standpipe Tube well/borehole Protected dug well Protected spring Rainwater collection Improved sanitation Flush/pour flush to: piped sewer system septic tank pit latrine Ventilated improved pit (VIP) latrine Pit latrine with slab Composting toilet Unimproved water supply Unprotected dug well Unprotected spring Cart with small tank/drum Tanker truck Surface water (river, dam, lake, pond, stream, canal, irrigation canal) Bottled water Unimproved sanitation Flush/Pour flush to elsewhere Pit latrine without slab/open pit bucket Hanging toilet/hanging latrine No facilities, bush or field

6. Water: Urban and rural disparities 2006 84% without access live in rural areas 84% without access live in rural areas WHO/UNICEF JMP, 2008 Urban Rural 0% - 50% 50% - 75% 76% - 90% 91% - 100% No or insufficient data

9. 1. Introduction 2. Data sources 3. JMP Methodology 4. Rationale for monitoring

10. Data sources on access to water supply and sanitation  1980 – 1997 Reported data from Governments  1997 – data from household surveys and censuses  JMP data sources are primary sources: National household sample surveys (DHS, MICS, LSMS, CWIQ, WHS, HBS, H&N, RHS, PAPFAM etc) National household sample surveys (DHS, MICS, LSMS, CWIQ, WHS, HBS, H&N, RHS, PAPFAM etc) National census National census Note: JMP is not involved in primary data collection Note: JMP is not involved in primary data collection

13. JMP – data base (2007)  Data for +/- 170 countries  600+ results of HH surveys + Censuses from 1985 – 2006  Bulk of surveys for LDCs, SSA, larger developing countries  30 - 40 new survey results per year  Frequency for most developing countries one survey every three years

14. How does the JMP obtain data?  UNICEF Country offices – annual submission of new survey/census data to HQ  MICS/DHS/WHS - through UNICEF, ORC- MACRO and WHO  IHSN – International Household Survey Network  Web-searches from NSO websites  Direct contact with NSO’s

15. Survey validation  Do we know the survey and survey authorities?  Is the survey nationally representative?  Do we have the original source documentation?  Reliability check against other indicators

17. Monitoring MDG drinking water and sanitation targets  A country’s responsibility  At global level: JMP  Challenges:  Track progress over time  Track progress towards the MDG target vs. baseline year 1990 baseline year 1990  Ensure comparability over time  Ensure comparability of data among countries ( JMP specific challenge ) countries ( JMP specific challenge )

18. JMP methodology  Collection survey information  Validate survey information  Ensure comparability among different surveys (including some country level consultations)  Plot survey data on time scale (urban + rural)  Draw linear regression line  Calculate total coverage based on urban & rural coverage data

19. Adjustments made to survey or census data set (1) Example:  HBS ‘86: Latrine: 58%Improved  DHS ‘89: Pit: 62% Improved ?  Census ‘92: Open pit: 59%Not improved  MICS ‘95: Traditional latrine: 60%Improved?  How to interpret these categories?  Suggested re-classification: Pit latrine with a slab Pit latrine with a slab Pit latrine without a slab/open pit Pit latrine without a slab/open pit

20. Adjustments made to survey or census data set (2) Example:  DHS ‘98: Well: 22%Improved?  Census ‘00: Protected dug well: 14%Improved  Census ’00: Unprotected dug well: 6% Not Improved Did coverage drop by 22 -14 = 8% over the period 1990-2000?  Suggested re-classification: Tube well/borehole Tube well/borehole Protected well Protected well Unprotected well Unprotected well

21. Latest data point DHS 2002 :51%

22. Estimates Coverage 2004 = 50% Latest data point DHS 2002 :51%

23. Estimates Coverage 2004 = 50% = 54% 2006 = 57% Added Fictive data point 2005 :58%

24. Estimated Coverage 2004 estimate = 50% Latest data point DHS 2002 :51%

25. 2004 = 50% = 54% 2006 = 57% Added Fictive data point 2005 :58%Estimated Coverage 2004 = 50% = 49% 2006 = 52% Added Fictive data point 2005 :49%

26. JMP Methodology  Per country: Trendlines for urban and rural sanitation coverage Trendlines for urban and rural sanitation coverage Trendlines for urban and rural drinking water coverage Trendlines for urban and rural drinking water coverage  Population data from UN Population Division Total population Total population proportion urban population proportion urban population  Calculate total national coverage Note: JMP does not take total coverage data directly from surveys or census data Note: JMP does not take total coverage data directly from surveys or census data

27. 1. Introduction 2. Data sources 3. JMP Methodology 4. Reconciling national and international monitoring

28. Data discrepancies  Use of different definitions of access  Use of different population data  JMP always uses projections – countries often report on latest census or survey findings  Difference in denominator population vs. households

29. Questions How to reconcile definitional issues between national and international monitoring? Should international definitions take into account (some) national definitions? E.g. shared facilities, traditional latrines? Should international definitions take into account (some) national definitions? E.g. shared facilities, traditional latrines? Should national data (and definitions) be published alongside international estimates? Should national data (and definitions) be published alongside international estimates? At what point should line ministries get involved in the discussion on definitions and what if they propose additional access criteria? At what point should line ministries get involved in the discussion on definitions and what if they propose additional access criteria?  How to ensure survey data compatibility for national and international monitoring?  Reporting of latest survey data or use of projections?  How to ensure international monitoring uses all available survey data?

30. JMP Methodology - Summary   Primarily based on user data derived from household surveys and censuses rather than data reported by governments   Adjustments made to full historical series to ensure comparability over time and between countries   Use linear regression to extrapolate and interpolate reference years instead of using the latest household survey data
