Regional ‘4 per 1000’ Latin America and Caribbean Conference
The Latin American and Caribbean Soil Carbon Research Symposium (LAC Soil Carbon) 2025 – June 25-28, 2025 – Rio de Janeiro, Brazil
The Latin American and Caribbean Soil Carbon Research Symposium (LAC Soil Carbon) 2025 aims to promote the importance of sustainable agricultural production for socioeconomic development and food security at both regional and global levels.
Promoted by the Soil Carbon International Research Consortium (IRC) and the international “4 per 1000” Initiative, the event will focus on organic carbon in soil, an essential resource for agricultural production.
Over four days, researchers, students, experts and practitioners will gather to exchange ideas and discuss regional and global challenges in promoting sustainable agricultural practices and preserving soil health.
Simultaneous translation will be available during the event in three languages: English, Spanish and Portuguese.

Why do we talk about “4 for 1000” ?
The International “4 per 1000” Initiative encourages stakeholders to engage in a transition towards a regenerative, productive, highly resilient agriculture, based on appropriate land and soil management, which creates jobs and income and thus leads to sustainable development.
It aims to show that agriculture can provide concrete solutions to the challenge posed by climate change while meeting the challenge of food security through the implementation of agricultural practices adapted to local conditions: agroecology, agroforestry, conservation agriculture, landscape management, etc.
The Initiative facilitates the development of concrete actions on the ground, benefiting to both farmers and herders, who are the first to be affected by land degradation, and more broadly to the entire world population.
The Executive Secretariat of the international “4 per 1000” Initiative is hosted by The Alliance Bioversity International-CIAT, an international organization based in Montpellier (France).
