Evidence-Based Decision-Making

Together, SWA partners work to promote the development of a strong evidence-base that supports good decision-making.

High-quality, up-to-date information is critical if decision-makers are to be able to make appropriate and timely investment decisions (what services are needed where, by whom by when). Evidence is also needed on the impact of water, sanitation and hygiene. With a strong evidence base, investments are more likely to be targeted to the right people and places.

Many developing countries do not have robust sector monitoring and evaluation systems that are able to provide reliable and consistently accurate data or information to support decision-making.  Ideally, national processes provide information on sanitation and water service delivery, including Joint Sector Reviews and government-led annual performance reviews, which are designed to analyse where the gaps and bottlenecks remain, using data provided by national information management systems.
