Alliance of Bioversity and CIAT launches project with Global Methane Hub to develop a decision support tool for grazing management to cut livestock emissions

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Business Announcement

The Time2Graze project will develop and equip farmers in Latin America with tools that assess pasture availability to identify the optimal time to graze livestock

Supported by the Global Methane Hub, the Time2Graze project is co-led by the World Resources Institute (WRI), the Alliance Bioversity International and Center for Tropical Agriculture (CIAT), the National Agriculture Research Institute of Uruguay (INIA) and WWF.

While the initial focus for the Alliance is on Colombia and Brazil, the project aims to progressively expand its reach across tropical Latin America and the Caribbean.
