This paper offers an overview of the main theories shaping gender-related policy that originated in development and that have been applied to relief. The analysis considers the tensions between maintaining theoretical integrity and managing practical operational concerns, bringing into question what is adaptable and applicable within an emergency context. It is not necessary to reinvent the wheel by developing a separate set of theories and tools for relief; there is overlap between the two. This creates an opportunity for development to inform relief and for relief to inform development. Included is a summary of the major gender planning and analysis frameworks for development and relief.
