The Global Water Initiative (GWI) was an action-research and advocacy programme that ran from 2008-17. The project is now closed. This site is no longer being updated, but allows access to GWI outputs until 1 October 2020 when it will also close. After that date, information about the project and core GWI technical publications will continue to be available from the IIED website and Publications Library.

Pioneering an outcome-based approach to M&E

Our methodology for monitoring and evaluation adopted an outcome-based (or results-based) approach. This allowed us to assess our effectiveness in achieving success with people, processes and collaborating institutions.

We gathered a diverse set of data to measure our progress, including baseline data at the beginning of the initiative. We published annual reports against a set of 11 outcomes, which in turn measured progress against the 3 global GWI strategic objectives.

We have produced a set of resources documenting our M&E work.


GWI’s strategic objectives and outcomes sought in West Africa


Strategic Objective 1: Vulnerable, marginalised groups are actively involved in design, implementation and evaluation of multiple water use service delivery and governance

  • Outcome A: Women and children spend less time collecting water.
  • Outcome B: People always drink clean water.
  • Outcome C: Communities show improved hygiene behaviours.
  • Outcome D: Absence of serious water-related conflict.
  • Outcome E: Communities participate in the elaboration and implementation of plans for water resources management.


Strategic Objective 2: A vibrant, cohesive and well-informed water constituency actively involved in improving delivery of IWRM (Integrated Water Resource Management)

  • Outcome F: Actions to ensure sustained water quality in rivers and groundwater.
  • Outcome G: Actions to ensure sustained groundwater levels and river flows.
  • Outcome H: Sector organisations work proactively together across the basin.
  • Outcome I: Active communication and learning on WRM within the basin.


Strategic Objective 3: Donors, investors and governments have greater awareness of and more support for IWRM

  • Outcome J:  Level of resourcing for WRM is markedly increased.
  • Outcome K: Importance and recognition of WRM in central / regional / decentralised government policy and strategy





Hydrological studies like this one play an important role in the sustainable management of water supplies, particularly as they should help reduce the long-term costs of borehole maintenance.

GWI activities in the Sirba basin are described, covering six municipalities in the East and Sahel Regions with 34 intervention villages.  Five local water management committees were set up and their intervention area within the Sirba basin determined.

This report presents graphs of progress made towards meeting the programme outcomes, showing evolution of regional indicators from 2010-2012 in the results-based monitoring of GWI.

GWI Mali carried out a 3 part monitoring study of hydrostatic levels of improved water points in the Baye, Diallassagou, Ouenkoro and Sokoura municipalities in the 15 months to September 2012.

GWI asked experts in IWRM from the 2IE Engineering Institute to visit all four project sites and to evaluate the approach and experience on IWRM that GWI was promoting with local partners.

GWI was initially conceived as a ten year programme and IIED, working with IWEL, developed a Monitoring and Evaluation strategy with two components.

GWI Senegal surveyed its project area near Tambacounda, Senegal in 2010 to establish the baseline for the long term M&E indicators. This report describes the project area, the sampling methods the data gathered and the challenges encountered.
