This document introduces the Global Agenda of Action in Support of Sustainable Livestock Sector Development (the Agenda). The Agenda aims to continuously improve the efficient use of natural resources in the livestock sector through a multi-stakeholder partnership approach. It focuses on three areas: closing the efficiency gap through application of existing technologies, restoring value to grasslands, and moving towards zero discharge of nutrients from manure. The partnership functions to build consensus, share knowledge, analyze issues, guide innovation and investments. An open platform, guiding group, and focus area groups have been established to implement the Agenda. Recent developments include side events, establishing the guiding group, scoping activities, and planning for the next multi-stakeholder platform meeting
