Agricultural science is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists.
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor 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.
The Green Revolution, or the Third Agricultural Revolution, was a period of technology transfer initiatives that saw greatly increased crop yields. These changes in agriculture began in developed countries in the early 20th century and spread globally until the late 1980s. In the late 1960s, farmers began incorporating new technologies such as high-yielding varieties of cereals, particularly dwarf wheat and rice, and the widespread use of chemical fertilizers, pesticides, and controlled irrigation.
Organic farming, also known as organic agriculture or 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. Indeed, so-called "organic pioneers" wanted to keep farming with nature, without being dependent on external inputs. 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 severely limiting synthetic substances. For instance, naturally-occurring pesticides such as garlic extract, bicarbonate of soda, or pyrethrin which is found naturally in the Chrysanthemum flower are permitted, while synthetic fertilizers and pesticides such as glyphosate are prohibited. Synthetic substances that are allowed, only in exceptional circumstances, 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 positively impacts sustainability, self-sufficiency, autonomy and independence, health, animal welfare, food security, and food safety. Organic farming can therefore be seen as part of the solution to the impacts of climate change, as also established by the Food and Agriculture Organisation (FAO).
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.
The International Rice Research Institute (IRRI) is an international agricultural research and training organization with its headquarters in Los Baños, Laguna, in the Philippines, and offices in seventeen countries. IRRI is known for its work in developing rice varieties that contributed to the Green Revolution in the 1960s which preempted the famine in Asia.
CGIAR is a global partnership that unites international organizations engaged in research about food security. CGIAR research aims to reduce rural poverty, increase food security, improve human health and nutrition, and sustainable management of natural resources.
Philippine Rice Research Institute (PhilRice) is a government corporate entity attached to the Department of Agriculture created through Executive Order 1061 on November 5, 1985 to help develop high-yielding and cost-reducing technologies for farmers.
The Collaborative Crop Research Program (CCRP) funds participatory, collaborative research on agroecological intensification (AEI). Funded projects typically link international, national, and local organizations with communities of smallholder farmers, researchers, development professionals, and other parties. Projects work together as part of a Community of Practice to generate technical and social innovations to improve nutrition, livelihoods, and productivity for farming communities in Africa and South America. Large-scale impact is realized when new ideas, technologies, or processes are adapted, when insights from research catalyze change in policy and practice, and when innovation inspires further success. The program is under the direction of Rebecca J. Nelson of Cornell University and Jane Maland Cady of the McKnight Foundation.
For millennia, agriculture has played an important role in the Chinese economy and society. By the time the People's Republic of China was established in 1949, virtually all arable land was under cultivation; irrigation and drainage systems constructed centuries earlier and intensive farming practices already produced relatively high yields. But little prime virgin land was available to support population growth and economic development. However, after a decline in production as a result of the Great Leap Forward (1958–60), agricultural reforms implemented in the 1980s increased yields and promised even greater future production from existing cultivated land.
In Nepal, the economy is dominated by agriculture. In the late 1980s, it was the livelihood for more than 90% of the population. Although only approximately 20% of the total land area was cultivable.
Upland rice is rice grown in dry-land environments. The term describes varieties of rice developed for rain-fed or less-intensely irrigated soil instead of flooded rice paddy fields or rice grown outside of paddies.
In the Philippines, rice production is an important aspect of the country's food supply and economy. The Philippines is the 8th-largest rice producer in the world, accounting for 2.8% of global rice production. The Philippines was also the world's largest rice importer in 2010. There are an estimated 2.4 million rice farmers in the Philippines as of 2020.
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.
