The Sphere philosophy is based on two core beliefs:
- People affected by disaster or conflict have the right to life with dignity and, therefore, the right to assistance; and
- All possible steps should be taken to alleviate human suffering arising out of disaster or conflict.
The Humanitarian Charter and Minimum Standards put these core beliefs into practice. The Protection Principles inform all humanitarian action, and the Core Humanitarian Standard contains commitments to support accountability across all sectors. Together, they form The Sphere Handbook, which has developed into one of the most widely referenced humanitarian resources globally.
This fourth edition marks the 20th anniversary of The Sphere Handbook and reflects changes in the humanitarian sector over that time. It includes new guidance for working in urban settings, for addressing Minimum Standards in protracted crises, and for delivering assistance through markets as a way to meet the standards.
