Decisions and actions of humanitarian actors have a profound effect on affected people. But how they hold humanitarian agencies to account for their actions? Affected people need an effective voice in the decision-making process in order to ensure accountable, contexualized and need-based responses. Hence, Start Fund Bangladesh (SFB) sought to broaden understanding of and commitment to common principles of accountability across its 27 local and 20 international NGO members by developing a common framework for accountability. Mechanism for Accountability to Affected Population is a set of 16 tools under four broad themes, Information provision, participation, complaint response mechanism (CRM), and learning. SFB piloted the set of 16 accountability tools for 16 responses implemented during 2020. It conducted a survey with all implementing partners, 25 organizations, to understand the most effective tools, challenging tools, and specific challenges and lessons learnt. In addition, all organizations submitted a MAAP adaptation status report covering the learnings from implementation of these tools. SFB compiled the results of the survey to come up key insights to be shared in the presentation. Although local agencies, received 85% of SFBs pooled fund and had a greater stake in decision making, the task of creating a more accountable and responsive system goes beyond localization. Accountability is not a theoretical pursuit; it is about holding power to account. Humanitarian agencies have a role to play in creating broad, informed participation of affected population and relevant stakeholders in decision-making process.
