Wes Jackson (born 1936) co-founded the Land Institute with Dana Jackson. He is also a member of the World Future Council.
Jackson was born and raised on a farm near Topeka, Kansas. After earning a BA in biology from Kansas Wesleyan University, an MA in botany from the University of Kansas, and a PhD in genetics from North Carolina State University. Wes Jackson established and served as chair of one of the United States' first environmental studies programs at California State University, Sacramento.[ citation needed ]
Jackson then chose to leave academia, returning to his native Kansas, where he founded a non-profit organization, The Land Institute, in 1976. The Land Institute is working to develop perennial grains, pulses, and oilseed-bearing plants to be grown in ecologically intensified, diverse crop mixtures under its Natural Systems Agriculture program. In tandem with these sustainable agriculture efforts, the Ecosphere Studies program seeks to change the way people think about the world and their place in it, through educational and cultural projects with a perennial perspective. Jackson stepped down from the presidency of The Land Institute in 2016, [1] but still works in the Ecosphere Studies program.
The Land Institute has explored alternatives in appropriate technology, environmental ethics, and education, but a research program in sustainable agriculture eventually became central to its work. In 1978, Jackson proposed the development of a perennial polyculture. He sought to have fields planted in polycultures, more than one variety of plant in a field, like diverse plants grow together in nature.
Jackson also wanted to use perennials, which would not need to be replanted every year - reducing the need for frequent tillage, preventing erosion, and promoting plant-soil microbe relationships to establish and persist. [2] [3] The Land Institute attempts to breed plants not presently used in agriculture into effective producers of perennial grains in intercropping conditions. Jackson argues that this version of agriculture used "nature as model," and to pursue that end, The Land Institute has studied prairie ecology.
Now in its fourth decade, The Land Institute is beginning to demonstrate progress in developing the perennial crops called for in the Natural Systems Agriculture model. Programs in wheat, sorghum, and sunflower are generating crop lines displaying both perenniality and agriculturally-significant seed yield.
Research on integrating these new plants into polycultures also continues. The Land Institute is not itself developing machinery suitable for one-pass harvesting of grain polycultures. It instead takes the position that integration of existing materials separation technology into harvesters is a straightforward task, and will be accomplished by public and private agricultural engineers when the demand arrives.
Wes Jackson is the author of several books and is recognized as a leader in the international sustainable agriculture movement. In 1971, Wes Jackson's first efforts to address growing environmental concerns, react to social concerns growing from the civil rights movement and opposition to the Vietnam War, and answer student requests for more relevant materials, resulted in the environmental reader, "Man and the Environment". [4] [5] After leaving academia and establishing the Land Institute, Jackson published New Roots for Agriculture, partially in reaction to a report from the U.S. Government Accountability Office on soil erosion. [4] [6]
This book expanded on ideas presented in a 1978 article, "Towards a Sustainable Agriculture," [4] [7] about looking to natural ecosystems, such as the prairie, to help solve the problem of soil erosion. He collaborated with author Wendell Berry on "Meeting the Expectations of the Land," in response to a Council on Agricultural Science and Technology report on agrochemicals. [4] [8]
Jackson's Becoming Native to This Place, published in 1994, challenges readers to develop a relationship with their ecosystems and further develops the idea of Natural Systems Agriculture. He was a 1990 Pew Conservation Scholar and in 1992 became a MacArthur Fellow. [9] In 2000, he received the Right Livelihood Award "for his single-minded commitment to developing an agriculture that is both highly productive and truly ecologically sustainable." [10] His work is often referred to by author Wendell Berry, with whom Jackson has shared a longtime friendship and correspondence. [11]

In agriculture, monoculture is the practice of growing one crop species in a field at a time. Monocultures increase ease and efficiency in planting, managing, and harvesting crops short-term, often with the help of machinery. However, monocultures are more susceptible to diseases or pest outbreaks long-term due to localized reductions in biodiversity and nutrient depletion. Crop diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture or intercropping.
Permaculture is an approach to land management and settlement design that adopts arrangements observed in flourishing natural ecosystems. It includes a set of design principles derived using whole-systems thinking. It applies these principles in fields such as regenerative agriculture, town planning, rewilding, and community resilience. The term was coined in 1978 by Bill Mollison and David Holmgren, who formulated the concept in opposition to modern industrialized methods, instead adopting a more traditional or "natural" approach to agriculture.
The following outline is provided as an overview of and topical guide to sustainable agriculture:
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.
A land ethic is a philosophy or theoretical framework about how, ethically, humans should regard the land. The term was coined by Aldo Leopold (1887–1948) in his A Sand County Almanac (1949), a classic text of the environmental movement. There he argues that there is a critical need for a "new ethic", an "ethic dealing with human's relation to land and to the animals and plants which grow upon it".
Agroecosystems are the ecosystems supporting the food production systems in farms and gardens. As the name implies, at the core of an agroecosystem lies the human activity of agriculture. As such they are the basic unit of study in Agroecology, and Regenerative Agriculture using ecological approaches.
In agriculture, polyculture is the practice of growing more than one crop species together in the same place at the same time, in contrast to monoculture, which had become the dominant approach in developed countries by 1950. Traditional examples include the intercropping of the Three Sisters, namely maize, beans, and squashes, by indigenous peoples of Central and North America, the rice-fish systems of Asia, and the complex mixed cropping systems of Nigeria.
The Land Institute is an American nonprofit research, education, and policy organization dedicated to sustainable agriculture, based in Salina, Kansas. Their goal is to develop an agricultural system based on perennial crops that "has the ecological stability of the prairie and a grain yield comparable to that from annual crops".
Wendell Erdman Berry is an American novelist, poet, essayist, environmental activist, cultural critic, and farmer. Closely identified with rural Kentucky, Berry developed many of his agrarian themes in the early essays of The Gift of Good Land (1981) and The Unsettling of America (1977). His attention to the culture and economy of rural communities is also found in the novels and stories of Port William, such as A Place on Earth (1967), Jayber Crow (2000), and That Distant Land (2004).
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. The environmental degradation process amplifies the impact of environmental issues which leave lasting impacts on the environment.
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.
In agriculture, monocropping is the practice of growing a single crop year after year on the same land. Maize, soybeans, and wheat are three common crops often monocropped. Monocropping is also referred to as continuous cropping, as in "continuous corn." Monocropping allows for farmers to have consistent crops throughout their entire farm. They can plant only the most profitable crop, use the same seed, pest control, machinery, and growing method on their entire farm, which may increase overall farm profitability.
Agricultural philosophy is, roughly and approximately, a discipline devoted to the systematic critique of the philosophical frameworks that are the foundation for decisions regarding agriculture. Many of these views are also used to guide decisions dealing with land use in general. In everyday usage, it can also be defined as the love of, search after, and wisdom associated with agriculture, as one of humanity's founding components of civilization. However, this view is more aptly known as agrarianism. In actuality, agrarianism is only one philosophy or normative framework out of many that people use to guide their decisions regarding agriculture on an everyday basis. The most prevalent of these philosophies will be briefly defined below.
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.
Perennial rice are varieties of long-lived rice that are capable of regrowing season after season without reseeding; they are being developed by plant geneticists at several institutions. Although these varieties are genetically distinct and will be adapted for different climates and cropping systems, their lifespan is so different from other kinds of rice that they are collectively called perennial rice. Perennial rice—like many other perennial plants—can spread by horizontal stems below or just above the surface of the soil but they also reproduce sexually by producing flowers, pollen and seeds. As with any other grain crop, it is the seeds that are harvested and eaten by humans.
A perennial grain is a grain crop that lives and remains productive for two or more years, rather than growing for only one season before harvest, like most grains and annual crops. While many fruit, nut and forage crops are long-lived perennial plants, all major grain crops presently used in large-scale agriculture are annuals or short-lived perennials grown as annuals. Scientists from several nations have argued that perennial versions of today's grain crops could be developed and that these perennial grains could make grain agriculture more sustainable.
Perennial crops are a perennial plant species that are cultivated and live longer than two years without the need of being replanted each year. Naturally perennial crops include many fruit and nut crops; some herbs and vegetables also qualify as perennial. Perennial crops have been cultivated for thousands of years; their cultivation differs from the mainstream annual agriculture because regular tilling is not required and this results in decreased soil erosion and increased soil health. Some perennial plants that are not cultivated as perennial crops are tomatoes, whose vines can live for several years but often freeze and die in winters outside of temperate climates, and potatoes which can live for more than two years but are usually harvested yearly. Despite making up 94% of plants on earth, perennials take up only 13% of global cropland. In contrast, grain crops take up about 70% of global cropland and global caloric consumption and are largely annual plants.
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, improving the water cycle, enhancing ecosystem services, supporting biosequestration, increasing resilience to climate change, and strengthening the health and vitality of farm soil.
Christian doctrines, ideologies and beliefs have influenced the manner in which human interactions with land, soil, and plants are manifested, both as a historical interplay between Christianity and land, and more contemporary movements where diverse sets of biblical readings, theological interpretations and Christian ethics are manifested in Christian approaches to food production.
