  1. Lessons from the Field - Impact Evaluation of SDN Projects:A Water and Sanitation Project in Paraguay Maria Angélica Sotomayor (LCSUW) and Luis A. Andrés (LCSSD) Tuesday February 26, 2008 Time: 12:15 to 5:30 PM Room: I2-220

  2. Rural Water and Sanitation in Paraguay From the 4th Rural W&S Project to …a New 5th Intervention

  3. Rural Water and Sanitation Projects (I to IV) in PY

  4. A Successful Project? • 30 year sustainability test • No system collapsed • All targets met or exceeded • Innovative pilots: first OBA scheme in the water sector ever.. • Satisfied clients/beneficiaries… ….NO DATA TO PROVE IT!!

  5. How to move forward? Prepare a solid M&E system – IMPACT EVALUATION • Results framework • Indicators • Baseline • Design features: randomized intervention -

  6. The New Project PDO: Improve quality of life of rural population Indicator: • Reduce the morbidity rate (diarrhea,parasitosis) related to water and basic sanitation in rural population

  7. Goals / purpose • Sustainable access to potable water and sanitation services in the population of up to 10.000 inhabitants • # of people served with potable water. • # of people served with sanitation. • Strengthen the management capacity of the community based organizations responsible for rural W&S service delivery • Increase xx% of Water Boards that honor financial responsibilities • Increase xx% of Water Boards joining Associations of Water Boards • # of Water Boards that adopt measures to improve accountability

  8. Components • Investments • Rural water • PSP • Indigenous systems • Individual sanitation solutions • Simplified sewerage • Hand-washing • Institutional strengthening • Central Agency - SENASA • Water boards • Associations of water boards

  9. Outcomes Do improvements in water access (and sanitation) in rural (and urban) areas in Paraguay: • reduce the incidence of water related illness (diarrhea, etc)? For any specific group? • improve the nutritional level of the children? • decrease infant mortality? • change intra-household behavior such as time usage, access to education, and/or productivity?

  10. Identification strategy Random assignment? • Very hard to do this in INF’s interventions (mainly due to engineering constrains); • Unit of observation are the communities rather than the HHs; • Self selection: local communities have to be eligible, prepare a project, apply for funds, and commit 15% of the project value (in kind and cash); • But: ~200 communities (already selected) will be intervened in 4 years and the government has no capacity to start everywhere at the same time…

  11. Identification strategy (cont.) So? What we agreed to do… • We will randomize the entrance of these communities (50 each year): those that will enter last will be the control group for those that will enter first [“internal control group”]; Other (external) control groups? • Pipeline of projects for the (potential) 6th loan. In principle, these communities have similar characteristics => some of them may be an external CG; • Projects intervened in the 4th loan (assumption: trend for those intervened in the 4th loan is similar to the counterfactual); • Matching with those communities that did not apply (not self selected) to study the selection bias…

  12. Where we are… Building local capacities: • Team members and staff from the government attended the regional workshop on IE a year ago => they know (and accept) the commitments for this IE; • Working with Fundición Desarrollo(a local think tank); • This was discussed with different stake holders. Proper project preparation: • A project already has a (draft) design; • This design will be included in the PAD; • We are working together with a professor from Northwestern University; • Fundraising: for doing the data collection (it is very likely to get TF to complement the project’s budget).
