Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
Regenerative agriculture is not a specific practice. It combines a variety of sustainable agriculture techniques. [4] Practices include maximal recycling of farm waste and adding composted material from non-farm sources. [5] [6] [7] [8] Regenerative agriculture on small farms and gardens is based on permaculture, agroecology, agroforestry, restoration ecology, keyline design, and holistic management. Large farms are also increasingly adopting regenerative techniques, using "no-till" and/or "reduced till" practices.
As soil health improves, input requirements may decrease, and crop yields may increase as soils are more resilient to extreme weather and harbor fewer pests and pathogens. [9]
Regenerative agriculture mitigates climate change through carbon dioxide removal from the atmosphere and sequestration. Along with reduction of carbon emissions, carbon sequestration is gaining popularity in agriculture, and individuals as well as groups are taking action to fight climate change. [10]
Regenerative agriculture is based on various agricultural and ecological practices, with a particular emphasis on minimal soil disturbance and the practice of composting. [11] Similar ideas focus on "sea minerals." [12] [13] His work led to innovations in no-till practices, such as slash and mulch in tropical regions. [14] [15] [16] Sheet mulching is a regenerative agriculture practice that smothers weeds and adds nutrients to the soil below. [17] [18]
In the early 1980s, the Rodale Institute began using the term ‘regenerative agriculture’. [19] Rodale Publishing formed the Regenerative Agriculture Association, which began publishing regenerative agriculture books in 1987 and 1988. [20]
By marching forward under the banner of sustainability we are, in effect, continuing to hamper ourselves by not accepting a challenging enough goal. I am not against the word sustainable, rather I favor regenerative agriculture.
However, the institute stopped using the term in the late 1980s, and it only appeared sporadically (in 2005 [21] and 2008), until they released a white paper in 2014, titled "Regenerative Organic Agriculture and Climate Change". [22] The paper's summary states, "we could sequester more than 100% of current annual CO2 emissions with a switch to common and inexpensive organic management practices, which we term 'regenerative organic agriculture.'" The paper described agricultural practices, like crop rotation, compost application, and reduced tillage, [22] that are similar to organic agriculture methods. [23]
In 2002, Storm Cunningham documented the beginning of what he called "restorative agriculture" in his first book, The Restoration Economy. Cunningham defined restorative agriculture as a technique that rebuilds the quantity and quality of topsoil, while also restoring local biodiversity (especially native pollinators) and watershed function. Restorative agriculture was one of the eight sectors of restorative development industries/disciplines in The Restoration Economy. [24]
Regenerative agriculture has showed up in academic research since the early to mid 2010s in the fields of environmental science, plant science, and ecology. [25] As the term expands in use, many books have been published on the topic and several organizations started to promote regenerative agriculture techniques. Allan Savory gave a TED talk on fighting and reversing climate change in 2013. He also launched The Savory Institute, which educates ranchers on methods of holistic land management. Abe Collins created LandStream to monitor ecosystem performance in regenerative agriculture farms. [26] Eric Toensmeier had a book published on the subject in 2016. [27] However, researchers at Wageningen University in the Netherlands found there to be no consistent definition of what people referencing "regenerative agriculture" meant. They also found that most of the work around this topic were instead the authors' attempt at shaping what regenerative agriculture meant. [4]
In 2011, the (not for profit) Mulloon Institute was founded in New South Wales, Australia, to develop and promote regenerative practices to reclaim land as water-retentive areas by slowing the loss of water from land. [28] The members of the Institute created a 22-weir in-stream project with neighbours over 2 kilometers of Mulloon Creek. A study indicates that the outcomes were positive but relatively unpredictable, and that suitability of ground conditions on site was a key for success. [29] Bottom-up change in the context of Australian regenerative agriculture is a complex set of narratives and barriers to change affecting farmers. [30] A West Australian government funded survey of land hydration was conducted by the Mulloon Institute in June 2022, which concluded that water retention projects supported the regeneration of native plant species. [31]
Founded in 2013, 501(c)3 non-profit Kiss the Ground was one of the first to publicize the term to a broader audience. Today the group runs a series of media, farmland, education, and policy programs to raise awareness around soil health and support farmers who aim to transition from conventional to regenerative land management practices. [32] The film Kiss the Ground , executive produced by Julian Lennon and Gisele Bündchen and narrated by Woody Harrelson, was released in 2020. [33] A follow-up documentary, Common Ground, premiered in 2023 and was the recipient of the 2023 Human/Nature Award at the Tribeca Film Festival. [34]
Not all regenerative systems emphasize ruminants. In 2017, Reginaldo Haslett Marroquin published "In the Shadow of Green Man" with Per Andreeason, [35] which detailed Haslett Marroquin's early life as a campesino in Guatemala and how these experiences led him to develop regenerative poultry agroforestry systems that are now being practiced and expanding in the United States and elsewhere. [36] [37]
Several large corporations have also announced regenerative agriculture initiatives in the last few years. In 2019, General Mills announced an effort to promote regenerative agriculture practices in their supply chain. The farming practices have received criticism from academic and government experiments on sustainability in farming. In particular, Gunsmoke Farm partnered with General Mills to transition to regenerative agriculture practices and become a teaching hub for others. Experts from the area have expressed concerns about the farm now doing more harm than good, with agronomist Ruth Beck stating that "Environmental marketing got ahead of what farmers can actually do". [38]
In February 2021, the regenerative agriculture market gained traction after Joe Biden's Secretary of Agriculture Tom Vilsack made reference to it during his Senate Confirmation hearing. The Biden administration wants to utilize $30 billion from the USDA's Commodity Credit Corporations to incentivise farmers to adopt sustainable practices. [39] Vilsack stated in the hearing, "It is a great tool for us to create the kind of structure that will inform future farm bills about what will encourage carbon sequestration, what will encourage precision agriculture, what will encourage soil health and regenerative agricultural practices." [40] After this announcement from the Biden administration, several national and international corporations announced initiatives into regenerative agriculture. [41] [42] [43] During the House of Representatives Committee on Agriculture's first hearing on climate change, Gabe Brown, a proponent of regenerative agriculture, testified about the role of regenerative agriculture in both the economics and sustainability of farming. [44]
In 2021, PepsiCo announced that by 2030 they will work with the farmers in their supply chain to establish regenerative agriculture practices across their approximately 7 million acres. [45] [43] In 2021, Unilever announced an extensive implementation plan to incorporate regenerative agriculture throughout their supply chain. [42] [46] VF Corporation, the parent company of The North Face, Timberland, and Vans, announced in 2021 a partnership with Terra Genesis International to create a supply chain for their rubber that comes from sources utilizing regenerative agriculture. [41] [47] Nestle announced in 2021 a $1.8 billion investment in regenerative agriculture in an effort to reduce their emissions by 95%. [48]
Several days before the opening of the 2022 United Nations Climate Change Conference, a report was published, sponsored by some of the biggest agricultural companies. The report was produced by Sustainable Markets Initiative, an organisation of companies trying to become climate friendly, established by King Charles III. According to the report, regenerative agriculture is already implemented on 15% of all cropland. Despite this, the rate of transition is "far too slow" and must be tripled by the year 2030 to prevent the global temperature passing the threshold of 1.5 degrees above preindustrial levels. Agricultural practices must immediately change in order to avoid the damage that would result. One of the authors emphasised that “The interconnection between human health and planetary health is more evident than ever before.” The authors proposed a set of measures for accelerating the transition, like creating metrics for measuring how much farming is sustainable, and paying farmers who will change their farming practices to more sustainable ones. [49]
Several individuals, groups, and organizations have attempted to define the principles of regenerative agriculture. In their review of the existing literature on regenerative agriculture, researchers at Wageningen University created a database of 279 research articles on regenerative agriculture. [4] Their analysis of this database found that people using the term regenerative agriculture were using different principles to guide regenerative agriculture efforts. [4] The 4 most consistent principles were found to be, 1) enhancing and improving soil health, 2) optimization of resource management, 3) alleviation of climate change, and 4) improvement of water quality and availability.
The organization The Carbon Underground created a set of principles that have been signed on to by a number of non-profits and corporations including Ben & Jerry's, Annie's, and the Rodale Institute, which was one of the first organization to use the term "Regenerative Agriculture". [50] The principles they've outlined include building soil health and fertility, increase water percolation and retention, increasing biodiversity and ecosystem health, and reducing carbon emissions and current atmospheric CO2 levels. [50]
The group Terra Genesis International, and VF Corporation's partner in their regenerative agriculture initiative, created a set of 4 principles, which include: [51] [5]
Instead of focusing on the specifics of food production technologies, human ecologist Philip Loring suggests a food system-level focus on regeneration, arguing that it is the combination of flexibility and diversity in our food systems that supports regenerative ecological practices. [52] Loring argues that, depending on the relative flexibility of people in the food system with respect to the foods they eat and the overall diversity of foods being produced and harvested, food systems can fall into one of four general patterns:
Loring's typology is based on a principle he calls the Conservation of Change, which states that change must always happen somewhere in ecosystems, and derives from the Second Law of Thermodynamics and Barry Commoner's premise in that, in ecosystems, "there is no free lunch".
Practices and principles used in regenerative farming include: [7] [5] [53] [54]
Conventional agricultural practices such as plowing and tilling release carbon dioxide (CO2) from the soil by exposing organic matter to the surface and thus promoting oxidation. [65] It is estimated that roughly a third of the total anthropogenic inputs of CO2 to the atmosphere since the industrial revolution have come from the degradation of soil organic matter [65] and that 30–75% of global soil organic matter has been lost since the advent of tillage-based farming. [66] Greenhouse gas (GHG) emissions associated with conventional soil and cropping activities represent 13.7% of anthropogenic emissions, or 1.86 Pg-C y−1. [66] The raising of ruminant livestock also contributes GHGs, representing 11.6% of anthropogenic emissions, or 1.58 Pg-C y−1. [66] Furthermore, runoff and siltation of water bodies associated with conventional farming practices promote eutrophication and emissions of methane. [66]
Regenerative agriculture practices such as no-till farming, rotational grazing, mixed crop rotation, cover cropping, and the application of compost and manure have the potential to reverse this trend. No-till farming reintroduces carbon back into the soil as crop residues are pressed down when seeding. Some studies suggest that adoption of no-till practices could triple soil carbon content in less than 15 years. [65] Additionally, 1 Pg-C y−1, representing roughly a fourth to a third of anthropogenic CO2 emissions, [67] may be sequestered by converting croplands to no-till systems on a global scale. [65]
There is mixed evidence on the carbon sequestration potential of regenerative grazing. A meta-analysis of relevant studies between 1972 and 2016 found that Holistic Planned Grazing had no better effect than continuous grazing on plant cover and biomass, although it may have benefited some areas with higher precipitation. [68] However, some studies have found positive impacts compared to conventional grazing. One study found that regenerative grazing management, particularly adaptive multipaddock (AMP) grazing, has been shown to reduce soil degradation compared to continuous grazing and thus has the potential to mitigate carbon emissions from soil. [66] Another study found that crop rotation and maintenance of permanent cover crops help to reduce soil erosion as well, and in conjunction with AMP grazing, may result in net carbon sequestration. [66]
There is a less developed evidence base comparing regenerative grazing with the absence of livestock on grasslands. Several peer-reviewed studies have found that excluding livestock completely from semi-arid grasslands can lead to significant recovery of vegetation and soil carbon sequestration. [69] [70] [71] [72] [73] A 2021 peer-reviewed paper found that sparsely grazed and natural grasslands account for 80% of the total cumulative carbon sink of the world’s grasslands, whereas managed grasslands (i.e. with greater livestock density) have been a net greenhouse gas source over the past decade. [74] A 2011 study found that multi-paddock grazing of the type endorsed by Savory resulted in more soil carbon sequestration than heavy continuous grazing, but very slightly less soil carbon sequestration than "graze exclosure" (excluding grazing livestock from land). [75] Another peer-reviewed paper found that if current pastureland was restored to its former state as wild grasslands, shrublands, and sparse savannas without livestock this could store an estimated 15.2 - 59.9 Gt additional carbon. [76]
The total carbon sequestration potential of regenerative grazing has been debated between advocates and critics. One study suggests that total conversion of livestock raising to AMP grazing practices coupled with conservation cropping has the potential to convert North American farmlands to a carbon sink, sequestering approximately 1.2 Pg-C y−1. [66] Over the next 25–50 years, the cumulative sequestration potential is 30-60 Pg-C. Additions of organic manures and compost further build soil organic carbon, thus contributing to carbon sequestration potential. [67] However, a study by the Food and Climate Research Network in 2017 estimates that, on the basis of meta-study of the scientific literature, the total global soil carbon sequestration potential from grazing management ranges from 0.3-0.8 Gt CO2eq per year, which is equivalent to offsetting a maximum of 4-11% of current total global livestock emissions, and that “Expansion or intensification in the grazing sector as an approach to sequestering more carbon would lead to substantial increases in methane, nitrous oxide and land use change-induced CO2 emissions”, leading to an overall increase in emissions. [77] Consistent with this, Project Drawdown (referenced in the film Kiss the Ground) estimates the total carbon sequestration potential of improved managed grazing at 13.72 - 20.92 Gigatons CO2eq between 2020–2050, equal to 0.46-0.70 Gt CO2eq per year. [78] A 2022 peer-reviewed paper estimated the carbon sequestration potential of improved grazing management at a similar level of 0.15-0.70 Gt CO2eq per year. [79]
A research made by the Rodale institute suggests that a worldwide transition to regenerative agriculture can soak more than 100% of the CO2 currently emitted by people. [80]
Soil organic matter is the primary sink of nutrients necessary for plant growth such as nitrogen, phosphorus, zinc, sulfur, and molybdenum. [67] Conventional tillage-based farming promotes rapid erosion and degradation of soil organic matter, depleting soil of plant nutrients and thus lowering productivity. [65] Tillage, in conjunction with additions of inorganic fertilizer, also destroys soil microbial communities, reducing production of organic nutrients in soil. [65] In contrast, use of organic fertilizer will significantly increase the organic matter in the soil. [65] Practices that restore organic matter may be used to increase the total nutrient load of soil. [67] For example, regenerative management of ruminant livestock in mixed-crop and grazing agroecosystems has been shown to improve soil nutrient cycling by encouraging the consumption and decomposition of residual crop biomass and promoting the recovery of nitrogen-fixing plant species. [66] Regenerative crop management practices, namely the use of crop rotation to ensure permanent ground cover, have the potential to increase soil fertility and nutrient levels if nitrogen-fixing crops are included in the rotation. [66] Crop rotation and rotational grazing also allow the nutrients in soil to recover between growing and grazing periods, thus further enhancing overall nutrient load and cycling. [67]
The soil microbiome which consist of bacteria, fungi, and other microorganisms play an essential role in nutrient cycling by decomposing organic matter and releasing essential nutrients for plant growth. [81] Their activities are needed for decomposition and mineralization processes, which help to transform complex organic compounds into simpler forms that plants can absorb. [82] In nitrogen cycling, nitrogen-fixing bacteria convert organic nitrogen into ammonium (NH₄⁺), which is then converted into nitrate (NO₃⁻) by nitrifying bacteria. [83] While both ammonium and nitrate are important for plant growth, nitrate is the most preferred for many plants due to its mobility, less toxicity, and efficient transport systems. Ammonium is also a great alternative as it is more readily assimilated once inside the plant, it can cause toxicity if taken up in excess. [83] Environmental conditions such as soil pH, and nutrient availability play major roles in determining which form of nitrogen is absorbed first [83] . Soil microbes also play a key role in phosphorus cycling, helping to dissolve phosphorus from organic material for plant availability. [83] A diverse microbial community also helps to prevent soil-borne diseases and reduces the need for synthetic fertilizers. [84]
Conventional farming disrupts nutrient cycling by using practices like tillage, which breaks down soil structure, reduces soil organic matter (SOM), and negatively impacts the overall soil health. [81] Conventional practices lead to reduced crop yields, increased reliance on synthetic fertilizers, and environmental problems like nutrient runoff and water pollution. [85] Over-reliance on synthetic fertilizers depletes soil health by favoring the growth of certain microorganisms over others, thereby reducing microbial diversity, organic matter decomposition, leading to soil degradation. [84] In contrast, regenerative agriculture promotes practices that enhance soil health and nutrient cycling. [86] These practices include reduced tillage which helps to preserve SOM, the use of organic fertilizers such as compost for soil enrichment, incorporating regenerative livestock management, practicing crop rotation with leguminous plants like soybean to promote nitrogen fixation that occurs from the symbiotic relationship between nitrogen-fixing bacteria and the root nodules. [87] Integrating livestock into cropping systems has been shown to improve nutrient cycling as animal manure enriches the soil and promotes microbial diversity. [88] Cover cropping is another practice that helps to prevent erosion, leading to healthier and more resilient soils. [89]
Conventional agricultural practices are generally understood to simplify agroecosystems through introduction of monocultures and eradication of diversity in soil microbial communities through chemical fertilization. [90] In natural ecosystems, biodiversity serves to regulate ecosystem function internally, but under conventional agricultural systems, such control is lost and requires increasing levels of external, anthropogenic input. [90] By contrast, regenerative agriculture practices including polycultures, mixed crop rotation, cover cropping, organic soil management, and low- or no-tillage methods have been shown to increase overall species diversity while reducing pest population densities. [90] Additionally, practices that favor organic over inorganic inputs aid in restoring below-ground biodiversity by enhancing the functioning of soil microbial communities. [67] A survey of organic and conventional farms in Europe found that on the whole, species across several taxa were higher in richness and/or abundance on organic farms compared to conventional ones, especially species whose populations have been demonstrably harmed as a direct result of conventional agriculture. [91]
AMP grazing can help improve biodiversity since increased soil organic carbon stocks also promotes a diversity of soil microbial communities. [66] Implementation of AMP in North American prairies, for example, has been correlated with an increase in forage productivity and the restoration of plant species that had previously been decimated by continuous grazing practices. [66] Furthermore, studies of arid and semiarid regions of the world where regenerative grazing has been practiced for a long time following prior periods of continuous grazing have shown a recovery of biodiversity, grass species, and pollinator species. [66] Furthermore, crop diversification ensures that the agroecosystem remains productive when facing lower levels of soil fertility. [92] Higher levels of plant diversity led to increases in numerous factors that contribute to soil fertility, such as soil N, K, Ca, Mg, and C, in CEC and in soil pH. [93]

Some members of the scientific community have criticized some of the claims made by proponents of regenerative agriculture as exaggerated and unsupported by evidence. [94]
One of the prominent proponents of regenerative agriculture, Allan Savory, claimed in his TED talk that holistic grazing could reduce carbon-dioxide levels to pre-industrial levels in a span of 40 years. According to Skeptical Science:
"it is not possible to increase productivity, increase numbers of cattle and store carbon using any grazing strategy, never-mind Holistic Management [...] Long term studies on the effect of grazing on soil carbon storage have been done before, and the results are not promising.[...] Because of the complex nature of carbon storage in soils, increasing global temperature, risk of desertification and methane emissions from livestock, it is unlikely that Holistic Management, or any management technique, can reverse climate change. [95] "
Commenting on his TED talk "How to Fight Desertification and Reverse Climate Change", Savory has since denied claiming that holistic grazing can reverse climate change, saying that “I have only used the words address climate change… although I have written and talked about reversing man-made desertification”. [96] Savory has faced criticisms for claiming the carbon sequestration potential of holistic grazing is immune from empirical scientific study. [96] For instance, in 2000, Savory said that "the scientific method never discovers anything" and “the scientific method protects us from cranks like me". [97] A 2017 factsheet authored by Savory stated that “Every study of holistic planned grazing that has been done has provided results that are rejected by range scientists because there was no replication!". [98] TABLE Debates sums this up by saying "Savory argues that standardisation, replication, and therefore experimental testing of HPG [Holistic Planned Grazing] as a whole (rather than just the grazing system associated with it) is not possible, and that therefore, it is incapable of study by experimental science", but "he does not explain how HPG can make causal knowledge claims with regards to combating desertification and climate mitigation, without recourse to science demonstrating such connections." [96]
According to a 2016 study published by the Swedish University of Agricultural Sciences, the actual rate at which improved grazing management could contribute to carbon sequestration is seven times lower than the claims made by Savory. The study concludes that holistic management cannot reverse climate change. [99] A study by the Food and Climate Research Network in 2017 concluded that Savory's claims about carbon sequestration are "unrealistic" and very different from those issued by peer-reviewed studies. [94]
Tim Searchinger and Janet Ranganathan have expressed concerns about emphasis upon "Practices That Increase Soil Carbon at the Field Level" because "overestimating potential soil carbon gains could undermine efforts to advance effective climate mitigation in the agriculture sector." Instead Tim Searchinger and Janet Ranganathan say, "preserving the huge, existing reservoirs of vegetative and soil carbon in the world’s remaining forests and woody savannas by boosting productivity on existing agricultural land (a land sparing strategy) is the largest, potential climate mitigation prize of regenerative and other agricultural practices. Realizing these benefits requires implementing practices in ways that boost productivity and then linking those gains to governance and finance to protect natural ecosystems. In short, produce, protect and prosper are the most important opportunities for agriculture." [100]
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the probability of developing resistant pests and weeds.
Intensive agriculture, also known as intensive farming, conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital, labour, agrochemicals and water, and higher crop yields per unit land area.
Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within sustainable food systems, it is important to develop flexible business processes and farming practices. Agriculture has an enormous environmental footprint, playing a significant role in causing climate change, water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes. Sustainable agriculture consists of environment friendly methods of farming that allow the production of crops or livestock without causing damage to human or natural systems. It involves preventing adverse effects on soil, water, biodiversity, and surrounding or downstream resources, as well as to those working or living on the farm or in neighboring areas. Elements of sustainable agriculture can include permaculture, agroforestry, mixed farming, multiple cropping, and crop rotation.
Agroecology is an academic discipline that studies ecological processes applied to agricultural production systems. Bringing ecological principles to bear can suggest new management approaches in agroecosystems. The term can refer to a science, a movement, or an agricultural practice. Agroecologists study a variety of agroecosystems. The field of agroecology is not associated with any one particular method of farming, whether it be organic, regenerative, integrated, or industrial, intensive or extensive, although some use the name specifically for alternative agriculture.
No-till farming is an agricultural technique for growing crops or pasture without disturbing the soil through tillage. No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain. Other possible benefits include an increase in the amount of water that infiltrates into the soil, soil retention of organic matter, and nutrient cycling. These methods may increase the amount and variety of life in and on the soil. While conventional no-tillage systems use herbicides to control weeds, organic systems use a combination of strategies, such as planting cover crops as mulch to suppress weeds.
Land management is the process of managing the use and development of land resources. One aim of sustainable land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion. Land resources are used for a variety of purposes which may include for example agriculture, forestry, water resource management, human settlements and tourism. Unsustainable land managements leads to land being over- or misused which in turn degrades the land, reduces productivity and disrupts natural equilibriums.
Agroforestry is a land use management system that integrates trees with crops or pasture. It combines agricultural and forestry technologies. As a polyculture system, an agroforestry system can produce timber and wood products, fruits, nuts, other edible plant products, edible mushrooms, medicinal plants, ornamental plants, animals and animal products, and other products from both domesticated and wild species.
Clifford Allan Redin Savory is a Zimbabwean livestock farmer and former Rhodesian politician. He is the president and co-founder of the Savory Institute. He originated holistic management, a systems thinking approach to managing resources.
Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components that belong together, as in microbiota, plants and animals. It is possible that a soil can be healthy in terms of ecosystem functioning but not necessarily serve crop production or human nutrition directly, hence the scientific debate on terms and measurements.
Soil carbon is the solid carbon stored in global soils. This includes both soil organic matter and inorganic carbon as carbonate minerals. It is vital to the soil capacity in our ecosystem. Soil carbon is a carbon sink in regard to the global carbon cycle, playing a role in biogeochemistry, climate change mitigation, and constructing global climate models. Microorganisms play an important role in breaking down carbon in the soil. Changes in their activity due to rising temperatures could possibly influence and even contribute to climate change. Human activities have caused a massive loss of soil organic carbon. For example, anthropogenic fires destroy the top layer of the soil, exposing soil to excessive oxidation.
The environmental impacts of animal agriculture vary because of the wide variety of agricultural practices employed around the world. Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent. Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming, free-range farming, intensive livestock production, and subsistence agriculture. The livestock sector also includes wool, egg and dairy production, the livestock used for tillage, and fish farming.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution.
Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, i.e. killing local wildlife or contaminating drinking water, and downstream effects such as dead zones caused by agricultural runoff is concentrated in large water bodies.
Soil management is the application of operations, practices, and treatments to protect soil and enhance its performance. It includes soil conservation, soil amendment, and optimal soil health. In agriculture, some amount of soil management is needed both in nonorganic and organic types to prevent agricultural land from becoming poorly productive over decades. Organic farming in particular emphasizes optimal soil management, because it uses soil health as the exclusive or nearly exclusive source of its fertilization and pest control.
Holistic Management in agriculture is an approach to managing resources that was originally developed by Allan Savory for grazing management., Holistic Management has been likened to "a permaculture approach to rangeland management". Holistic Management is a registered trademark of Holistic Management International. It has faced criticism from many researchers who argue it is unable to provide the benefits claimed.
Soil compaction, also known as soil structure degradation, is the increase of bulk density or decrease in porosity of soil due to externally or internally applied loads. Compaction can adversely affect nearly all physical, chemical and biological properties and functions of soil. Together with soil erosion, it is regarded as the "costliest and most serious environmental problem caused by conventional agriculture."
Soil regeneration, as a particular form of ecological regeneration within the field of restoration ecology, is creating new soil and rejuvenating soil health by: minimizing the loss of topsoil, retaining more carbon than is depleted, boosting biodiversity, and maintaining proper water and nutrient cycling. This has many benefits, such as: soil sequestration of carbon in response to a growing threat of climate change, a reduced risk of soil erosion, and increased overall soil resilience.
Carbon farming is a set of agricultural methods that aim to store carbon in the soil, crop roots, wood and leaves. The technical term for this is carbon sequestration. The overall goal of carbon farming is to create a net loss of carbon from the atmosphere. This is done by increasing the rate at which carbon is sequestered into soil and plant material. One option is to increase the soil's organic matter content. This can also aid plant growth, improve soil water retention capacity and reduce fertilizer use. Sustainable forest management is another tool that is used in carbon farming. Carbon farming is one component of climate-smart agriculture. It is also one way to remove carbon dioxide from the atmosphere.
Climate-smart agriculture (CSA) is a set of farming methods that has three main objectives with regards to climate change. Firstly, they use adaptation methods to respond to the effects of climate change on agriculture. Secondly, they aim to increase agricultural productivity and to ensure food security for a growing world population. Thirdly, they try to reduce greenhouse gas emissions from agriculture as much as possible. Climate-smart agriculture works as an integrated approach to managing land. This approach helps farmers to adapt their agricultural methods to the effects of climate change.
Regenerative cacao is defined as cacao that is produced on a farm that employs regenerative agriculture and agroforestry methods. It is most closely associated with the Ecuadorian chocolate company To’ak, the organic food supplier Navitas, the rainforest conservation organization TMA, and the social-agricultural enterprise Terra Genesis.
