This document summarizes a session on conducting a risk opportunity mapping study on water sanitation and hygiene (WSS) in Uganda to address corruption issues. It describes the purpose of a vulnerability assessment to identify areas within an organization that may be vulnerable to abuse. It provides an overview of Uganda's water sector including rural and urban supply managed by various entities. The methodology for Uganda's study included a desk review and stakeholder interviews to develop a corruption risk map. The map analyzed macro-level national integrity issues and sector-specific risks within water institutions. Findings identified weaknesses in regulatory independence, procurement practices, and human/financial capacity. Discussion focused on adapting the approach to other country contexts.
