The International Center for Tropical Agriculture (known as CIAT from its Spanish-language name Centro Internacional de Agricultura Tropical) is an international research and development organization dedicated to reducing poverty and hunger while protecting natural resources in developing countries.

In 2019, CIAT joined with Bioversity International (as the Alliance of Bioversity International and CIAT) to "deliver research-based solutions that harness agricultural biodiversity and sustainably transform food systems to improve people’s lives".

[4] CIAT has one of the 11 gene banks of the CGIAR, with a collection of more than 65,000 accessions of three crops: beans (37,000); tropical forages (23,000) and cassava (6,000), from more than 100 countries.

The goals are tolerances to drought, low phosphorus soils, and heat; in addition to improved nitrogen fixation.

CIAT coordinated the activities of the Pan-Africa Bean Research Alliance (PABRA) in 29 countries in Sub-Saharan Africa.
