GBV Minimum Standards
Read full descriptionHide full description
The GBV Minimum Standards mobile app presents 16 Minimum Standards for the prevention of and response to gender-based violence in emergencies. As a whole, the 16 Minimum Standards define what agencies working on specialized gender-based violence programming need to achieve to prevent and respond to gender-based violence, and deliver multisectoral services. The objective of the Minimum Standards is to establish a common understanding of what constitutes minimum prevention and response programming in emergencies. Each Standard in this resource represents a common agreement on what needs to be achieved for that specific programmatic element to be of adequate quality. The standards are universal; they are relevant for all emergency contexts. The GBV Minimum Standards app is a companion to the 2019 Inter-Agency Minimum Standards for Gender-Based Violence in Emergencies Programming.
