Agriculture encompasses crop and livestock production, aquaculture, fisheries, and forestry for food and non-food products. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output.
Pesticides are substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides, and many others. The most common of these are herbicides, which account for approximately 50% of all pesticide use globally. Most pesticides are used as plant protection products, which in general protect plants from weeds, fungi, or insects. In general, a pesticide is a chemical or biological agent that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or are disease vectors. Along with these benefits, pesticides also have drawbacks, such as potential toxicity to humans and other species.
Organic farming, also known as ecological farming or biological farming, is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. It originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture accounts for 70 million hectares globally, with over half of that total in Australia. Biological pest control, mixed cropping, and the fostering of insect predators are encouraged. Organic standards are designed to allow the use of naturally-occurring substances while prohibiting or strictly limiting synthetic substances. For instance, naturally-occurring pesticides such as pyrethrin are permitted, while synthetic fertilizers and pesticides are generally prohibited. Synthetic substances that are allowed include, for example, copper sulfate, elemental sulfur, and veterinary drugs. Genetically modified organisms, nanomaterials, human sewage sludge, plant growth regulators, hormones, and antibiotic use in livestock husbandry are prohibited. Organic farming advocates claim advantages in sustainability, openness, self-sufficiency, autonomy and independence, health, food security, and food safety.
Natura 2000 is a network of nature protection areas in the territory of the European Union. It is made up of Special Areas of Conservation and Special Protection Areas designated under the Habitats Directive and the Birds Directive, respectively. The network includes both terrestrial and Marine Protected Areas.
The Common Agricultural Policy (CAP) is the agricultural policy of the European Commission. It implements a system of agricultural subsidies and other programmes. It was introduced in 1962 and has since then undergone several changes to reduce the EEC budget cost and consider rural development in its aims. It has however, been criticised on the grounds of its cost, its environmental, and humanitarian effects.
An orchard is an intentional plantation of trees or shrubs that is maintained for food production. Orchards comprise fruit- or nut-producing trees that are generally grown for commercial production. Orchards are also sometimes a feature of large gardens, where they serve an aesthetic as well as a productive purpose. A fruit garden is generally synonymous with an orchard, although it is set on a smaller, non-commercial scale and may emphasize berry shrubs in preference to fruit trees. Most temperate-zone orchards are laid out in a regular grid, with a grazed or mown grass or bare soil base that makes maintenance and fruit gathering easy.
An agricultural subsidy is a government incentive paid to agribusinesses, agricultural organizations and farms to supplement their income, manage the supply of agricultural commodities, and influence the cost and supply of such commodities.
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance, maintenance of a permanent soil cover, and diversification of plant species. It enhances biodiversity and natural biological processes above and below the ground surface, which contribute to increased water and nutrient use efficiency and to improved and sustained crop production."
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range and consume wild vegetations in order to convert the otherwise indigestible cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
An environmental management scheme is a mechanism by which landowners and other individuals and bodies responsible for land management can be incentivised to manage their environment.
On 26 June 2003, EU farm ministers adopted a fundamental reform of the Common Agricultural Policy (CAP) and introduced a new Single Payment Scheme for direct subsidy payments to landowners.
Miscanthus × giganteus, also known as the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of 3–4 metres (13 ft) in one season. Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass.
Conservation grazing or targeted grazing is the use of semi-feral or domesticated grazing livestock to maintain and increase the biodiversity of natural or semi-natural grasslands, heathlands, wood pasture, wetlands and many other habitats. Conservation grazing is generally less intensive than practices such as prescribed burning, but still needs to be managed to ensure that overgrazing does not occur. The practice has proven to be beneficial in moderation in restoring and maintaining grassland and heathland ecosystems. Conservation or monitored grazing has been implemented into regenerative agriculture programs to restore soil and overall ecosystem health of current working landscapes. The optimal level of grazing and grazing animal will depend on the goal of conservation. Different levels of grazing, alongside other conservation practices, can be used to induce desired results.
Hill farming or terrace farming is an extensive farming in upland areas, primarily rearing sheep, although historically cattle were often reared extensively in upland areas. Fell farming is the farming of fells, a fell being an area of uncultivated high ground used as common grazing. It is a term commonly used in Northern England, especially in the Lake District and the Pennine Dales. Elsewhere, the terms hill farming or pastoral farming are more commonly used.
The agricultural policy of the United States is composed primarily of the periodically renewed federal U.S. farm bills. The Farm Bills have a rich history which initially sought to provide income and price support to US farmers and prevent them from adverse global as well as local supply and demand shocks. This implied an elaborate subsidy program which supports domestic production by either direct payments or through price support measures. The former incentivizes farmers to grow certain crops which are eligible for such payments through environmentally conscientious practices of farming. The latter protects farmers from vagaries of price fluctuations by ensuring a minimum price and fulfilling their shortfalls in revenue upon a fall in price. Lately, there are other measures through which the government encourages crop insurance and pays part of the premium for such insurance against various unanticipated outcomes in agriculture.
Agricultural land is typically land devoted to agriculture, the systematic and controlled use of other forms of life—particularly the rearing of livestock and production of crops—to produce food for humans. It is generally synonymous with both farmland or cropland, as well as pasture or rangeland.
The European Centre for Nature Conservation (ECNC) was a Dutch non-profit foundation which was active in the field of European nature and biodiversity policy between 1993 and 2017. It was set up as a network of university departments, expert centres and government agencies and operated as a European biodiversity expertise centre. The organization promoted sustainable management of natural resources and biodiversity, and aimed to stimulate interaction between science, society and policy.
Energy efficiency in agriculture refers to reducing the amount of energy required to provide agricultural products and services. The European Commission has policies related to energy efficiency, including in agriculture. The European Union has established measures to promote energy efficiency, including setting targets for energy savings, and requiring energy audits and management plans for large companies. The AGREE project conducted studies on energy efficiency in different agricultural production systems and proposed measures for improvement. The results of the project were summarized in reports that highlighted the opportunities and drawbacks for energy efficiency in agriculture in different European countries. Improving energy efficiency in agriculture contributes to reducing greenhouse gas emissions.
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.
The Biodiversity Monitoring Switzerland (BDM) is a Swiss Confederation programme for the long-term monitoring of species diversity in Switzerland.
