Food, Agriculture, and Land Use

Reduced / Sequestered

Human activity has transformed a significant fraction of the planet’s land, especially for growing food and harvesting forests. Land is the common ground of shelter, sustenance, feed for animals, fiber, timber, and some sources of energy, as well as the direct source of livelihood for billions of people.

Our pursuit of those ends often disrupts or displaces ecosystems, and the twin forces of a growing population and rising consumption mean the challenge of stewarding land in sustainable ways will only intensify. Today, agriculture and forestry activities generate 24% of greenhouse gas emissions worldwide.

How can we reduce the pressures on ecosystems and land, while meeting the growing demands for food and fiber worldwide? How can we do what we do on land better, tending it in ways that decrease emissions from agriculture and forestry?

The answers to these questions are critical for stemming greenhouse gases, sustaining the planet’s living systems, addressing food security, and protecting human health, all inextricably linked. Solutions in this sector are focused on waste and diets, ecosystem protection, and better agriculture practices.

Address Waste and Diets

By shifting diets and addressing food waste, the global demand for food can significantly drop. Eating lower on the food chain and ensuring what’s grown gets eaten is a powerful combination that lowers farming inputs, land-clearing, and all associated emissions.

Protect Ecosystems

When land and ecosystems are deliberately protected, activities that release carbon from vegetation and soil are stopped before they start. In addition, improving food production on existing farmland may reduce the pressure on other, nearby landscapes, thereby sparing them from clearing.

Shift Agriculture Practices

Better agriculture practices can lower emissions from cropland and pastures, including methane generated by growing rice and raising ruminants, nitrous oxide emitted from manure and overusing fertilizers, and carbon dioxide released by disturbing soils.

Farming and forestry practices can also support the role of land in removing greenhouse gases from the atmosphere. Many solutions that stop land-based emissions also enhance carbon sinks (explored below). Solutions in this sector are significant for improving food security and agricultural resilience as well, because many of them contribute to a more robust food system, better able to withstand climate impacts.
