Wyzwania i Persistent Barriers to Effectiveness

Despite the growing revidence base, many internationally funded WASH projects still fall short. The challenges are structural, financial, andbehavoural.

Funding Gaps andMisalingment

While total ODA for water and sanitation has risen, it still presents only a small fraction of overall development aid - around 5-6% of bilateral ODA. Moreover, funding is often front-loaded for construction with little allocated for long- term operation, constructes, or monitoring.
