Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It is not a single specific practice but a combination of various sustainable techniques. These methods focus on regenerating topsoil and increasing biodiversity. They also aim to improve the water cycle and enhance ecosystem services. A major goal is supporting biosequestration, which is the process of capturing carbon. This helps increase resilience to climate change. By strengthening the health and vitality of farm soil, these systems seek to create a more stable environment.

Farmers use several specific mechanisms to achieve these goals. One common method is the maximal recycling of farm waste. This often involves adding composted material from non-farm sources to the fields. Large farms often adopt "no-till" or "reduced till" practices. This means they avoid digging up or turning the soil deeply. Such methods help preserve the soil structure. Another technique is sheet mulching. This practice smothers weeds while adding nutrients to the soil below.

Through crop rotation, farmers grow different crops in sequence. This can lead to increased yields and fewer pests or pathogens. As soil health improves, the need for outside inputs may decrease.

Different scales of farming use different specialized approaches. Small farms and gardens often rely on permaculture and agroecology. They might also use agroforestry, which combines trees with crops. Other methods include restoration ecology and keyline design. Holistic management is another approach used on smaller scales. Large-scale operations focus more on large-scale mechanical changes. They often use reduced tillage to manage vast areas of land. These varied methods all share the goal of improving soil health and water retention.

History shows how these ideas have evolved over several decades. The Rodale Institute began using the term "regenerative agriculture" in the early 1980s. In 1987, the Regenerative Agriculture Association began publishing books on the subject. In 2002, Storm Cunningham documented "restorative agriculture." He defined it as a technique to rebuild topsoil and local biodiversity. Since the early to mid-2010s, regenerative agriculture has appeared more frequently in academic research. This research spans the fields of environmental science, plant science, and ecology. The term has expanded significantly in recent years.

Many organizations now work to promote these specific practices. In Australia, the Mulloon Institute was founded in 2011. They work to reclaim land as water-retentive areas. They even completed a 22-weir in-stream project over 2 kilometers of Mulloon Creek. In 2013, Allan Savory launched The Savory Institute to educate ranchers. He also gave a TED talk on reversing climate change. The non-profit Kiss the Ground was founded in 2013 to publicize these terms. They released a film in 2020 to raise awareness about soil health.

Large corporations have also entered this growing market. In 2019, General Mills announced an effort to promote these practices. PepsiCo announced in 2021 that it would work with farmers by 2030. They aim to implement these practices across 7 million acres. Unilever and Nestle have also announced major implementation plans. Nestle announced a $1.8 billion investment to reduce its emissions. However, some experts express concern about this corporate involvement. They worry that environmental marketing might outpace what farmers can actually achieve. Some fear corporations may use the term for marketing while neglecting substantive practices.

There are important connections between farming and global climate systems. Regenerative agriculture claims to mitigate climate change through carbon dioxide removal. This is known as carbon sequestration. A report by the Sustainable Markets Initiative stated that regenerative agriculture is on 15% of cropland. The report suggests this rate must triple by 2030. This change is needed to help prevent global temperatures from rising too much. The Biden administration also recognized this potential in 2021. Secretary of Agriculture Tom Vilsack noted that $30 billion could be used to incentivize these practices. This shows how farming, economics, and planetary health are deeply interconnected.
