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 process 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 damage to human or natural systems. It involves preventing adverse effects to soil, water, biodiversity, 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.
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.
The Smithsonian Conservation Biology Institute (SCBI) is a unit of the Smithsonian Institution located on a 3,200-acre (13 km2) campus located just outside the town of Front Royal, Virginia. An extension of the National Zoo in Washington, D.C., the SCBI has played a leading role in the fields of veterinary medicine, reproductive physiology and conservation biology since its founding in 1974.
The Long Term Ecological Research Network(LTER) consists of a group of over 1800 scientists and students studying ecological processes over extended temporal and spatial scales. Twenty-eight LTER sites cover a diverse set of ecosystems. It is part of the International Long Term Ecological Research Network (ILTER). The project was established in 1980 and is funded by the National Science Foundation. Data from LTER sites is publicly available in the Environmental Data Initiative repository and findable through DataONE search.
Ecological indicators are used to communicate information about ecosystems and the impact human activity has on ecosystems to groups such as the public or government policy makers. Ecosystems are complex and ecological indicators can help describe them in simpler terms that can be understood and used by non-scientists to make management decisions. For example, the number of different beetle taxa found in a field can be used as an indicator of biodiversity.
National Ecological Observatory Network (NEON) is a large facility program operated by Battelle Memorial Institute and funded by the National Science Foundation. In full operation since 2019, NEON gathers and provides long-term, standardized data on ecological responses of the biosphere to changes in land use and climate, and on feedback with the geosphere, hydrosphere, and atmosphere. NEON is a continental-scale research platform for understanding how and why our ecosystems are changing.
James J. Kay was an ecological scientist and policy-maker. He was a respected physicist best known for his theoretical work on complexity and thermodynamics.
Agroecosystem analysis is a thorough analysis of an agricultural environment which considers aspects from ecology, sociology, economics, and politics with equal weight. There are many aspects to consider; however, it is literally impossible to account for all of them. This is one of the issues when trying to conduct an analysis of an agricultural environment.
Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of and a specific element of agricultural biodiversity. Over the past 50 years, there has been a major decline in two components of crop diversity; genetic diversity within each crop and the number of species commonly grown.
DataONE is a network of interoperable data repositories facilitating data sharing, data discovery, and open science. Originally supported by $21.2 million in funding from the US National Science Foundation as one of the initial DataNet programs in 2009, funding was renewed in 2014 through 2020 with an additional $15 million. DataONE helps preserve, access, use, and reuse of multi-discipline scientific data through the construction of primary cyberinfrastructure and an education and outreach program. DataONE provides scientific data archiving for ecological and environmental data produced by scientists. DataONE's goal is to preserve and provide access to multi-scale, multi-discipline, and multi-national data. Users include scientists, ecosystem managers, policy makers, students, educators, librarians, and the public.
Eragrostis pilosa is a species of grass in the family Poaceae. It is native to Eurasia and Africa. It may or may not be native to North America. It is widely introduced, and it is a common weed in many areas.
The Indian Institute of Soil Science is an autonomous institute for higher learning, established under the umbrella of Indian Council of Agricultural Research (ICAR) by the Ministry of Agriculture, Government of India for advanced research in the field of soil sciences.
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.
Dr. C. Vernon Cole was a soil scientist known primarily for his work on nutrient cycling in agroecosystems. He was a member of Working Group II of the Intergovernmental Panel on Climate Change (IPCC) Second Assessment report, and the lead author of Chapter 23 “Agricultural Options for Mitigation of Greenhouse Gas Emissions”. The IPCC was awarded the Nobel Peace Prize in 2007.
The Jornada Biosphere Reserve is a UNESCO Biosphere Reserve in southern New Mexico. It is one of three biosphere reserves representing the Chihuahuan Desert. The area extends from the crest of the San Andres Mountains, which are dominated by shrub woodlands, to the Jornada Plains characterized by semi-desert grasslands.
Ivette Perfecto is an ecologist and professor at the University of Michigan. Her work focuses on complex ecosystem dynamics and the application of ecological theories to agricultural systems.
Ann M. Bartuska is an ecologist and biologist. She is a senior advisor at Resources for the Future and a former Deputy Under Secretary for Research, Education, and Economics (REE) at the United States Department of Agriculture and former USDA Chief Scientist.
Serita D. Frey is an American academic and ecologist, who serves as Professor of Environmental Science at the University of New Hampshire. Her research considers how human activities impact terrestrial ecosystems.
Stacy Philpott is an American ecologist who is a professor at the University of California, Santa Cruz. Her research considers agroecology and the conservation of biodiversity. She was elected a Fellow of the Ecological Society of America in 2021.
