![]() In addition, improving food production on existing farmland may reduce the pressure on other, nearby landscapes, sparing them from clearing. When we deliberately protect land and ecosystems, we stop activities that release carbon from vegetation and soil before they start. Eating lower on the food chain and ensuring what’s grown gets eaten is a powerful combination that lowers farming inputs, land clearing, and associated emissions. Shifting diets and addressing food waste can significantly reduce the global demand for food. ![]() Solutions in this sector are focused on waste and diets, ecosystem protection, and better agriculture practices. 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. How can we reduce the pressures on ecosystems and land, while meeting the growing demands for food and fiber worldwide? How can we manage land and other resources that provide food better, tending it in ways that decrease emissions from agriculture, fisheries, and forestry? Today, agriculture and forestry activities close to one-fourth of greenhouse gas emissions worldwide. ![]() 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. All told, the food, agriculture, and land use sector contributes 24 percent of anthropogenic greenhouse gas emissions. It also is the direct source of livelihood for billions of people. Land-including land at the edge and the bottom of the ocean-provides shelter, sustenance, feed for animals, fiber, timber, and some sources of energy. Human activity has transformed a significant fraction of the planet’s land, especially for growing food and harvesting forests.
