The new UNDG Resource Guide for Gender Theme Groups makes available to UN staff operating in the field a key knowledge resource for further enhancing coordinated action on gender equality and the empowerment of women by UNCTs. The structure and content of the Resource Guide address the evolving environment in which interagency gender coordination mechanisms have been functioning at the country level in support of gender mainstreaming within UNCTs. The Guide is anchored in the 2030 Agenda for sustainable development and the new programming guidance for UNCTs. It provides a menu of possible functional areas of focus of Gender Theme Groups based on real experiences in the field, complemented by an extensive set of practical examples of their work.
