Office of Climate Change, Biodiversity and Environment (OCB)

The Office of Climate Change, Biodiversity and Environment (OCB) works to ensure that countries and stakeholders respond to the challenges of climate change, biodiversity loss, and environmental degradation, keeping food and agriculture sustainability high on the agenda.

OCB contributes to all FAO aspirations, focusing on how the work for a better environment can contribute to better production, better nutrition and better livelihoods.

Areas of Work


FAO’s Office of Climate Change, Biodiversity and Environment foresees a future where governments, development partners,  civil society, academic institutions and the private sector work together to ensure sustainable agriculture and food systems, and  a climate-resilient world,  free from hunger and malnutrition, that conserves biodiversity and protects  the environment”.


OCB comprises over 200 professionals working with FAO Members and partners, to facilitate global dialogue, mobilize environmental and climate finance, and lead advocacy and actions to promote sustainable agriculture and food security within the global sustainability agenda.

Working through 5 workstreams: Climate Change, Biodiversity, Environment, Green Blue Finance, Innovation for Sustainability, OCB works across FAO’s seven core functions.

OCB coordinates initiatives across the organization with Members and partners to reach the targets of the Sustainable Development Goals (SDGs) related to climate change and natural resources, as the foundations to achieve other SDG targets, particularly those under SDG 1 End poverty, and SDG 2 Eradicate hunger.
