This presentation introduces policy influencing principles (policy influencing continuum and CLASP principles) and different levels of accountability in the context of the Watershed - empowering citizens programme. A distinction is made between social, financial and political accountability. Within the Watershed programme, there are three levels of accountability: local/national, international and The Netherlands. Budget tracking in Bangladesh and the Sanitation & Water for All (SWA) multi-stakeholder platform are examples of the first accountability two levels. In the Netherlands, Dutch civil society organisations (CSOs) are tracking the water, sanitation and hygiene (WASH) aid commitments of the Dutch Ministry of Foreign Affairs. A key message is that both monitoring services and monitoring budgets / financial flows are important for evidence-based advocacy. Presented by Roel Blesgraaf (Simavi) on 6 July 2016 at the IRC event: "Accountability tools to improve WASH service delivery", in The Hague.
