Version 2 (unedited). The Basic Needs Analysis (BNA) is a multi-sector needs analysis approach that can be applied in both sudden onset and protracted emergencies. The methodology comprises the Guidance (this document) presenting the conceptual BNA framework and related processes, and a Toolbox, which includes tools, templates, training materials, and examples drawn from its first pilot, in Borno State(Nigeria). The BNA is conceived to go hand in hand with the Facilitator’s Guide for the Response Options Analysis and Planning (a separate document), as it is part of a broader response planning process (see The BNA within the ). It shall be carried out with other assessments on the operational environment and would not add any value if undertaken in isolation.
