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.
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom.
Subsistence agriculture occurs when farmers grow crops to meet the needs of themselves and their families on smallholdings. Subsistence agriculturalists target farm output for survival and for mostly local requirements. Planting decisions occur principally with an eye toward what the family will need during the coming year, and only secondarily toward market prices. Tony Waters, a professor of sociology, defines "subsistence peasants" as "people who grow what they eat, build their own houses, and live without regularly making purchases in the marketplace".
A paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures. It was spread in prehistoric times by the expansion of Austronesian peoples to Island Southeast Asia, Southeast Asia including Northeastern India, Madagascar, Melanesia, Micronesia, and Polynesia. The technology was also acquired by other cultures in mainland Asia for rice farming, spreading to East Asia, Mainland Southeast Asia, and South Asia.
The Akha are an ethnic group who live in small villages at higher elevations in the mountains of Thailand, Myanmar, Laos and Yunnan Province in China. They made their way from China into Southeast Asia during the early 20th century. Civil war in Burma and Laos resulted in an increased flow of Akha immigrants and there are now 80,000 people living in Thailand's northern provinces of Chiang Rai and Chiang Mai.
Agriculture, forestry, and fishing form the primary sector of industry of the Japanese economy together with the Japanese mining industry, but together they account for only 1.3% of gross national product. Only 20% of Japan's land is suitable for cultivation, and the agricultural economy is highly subsidized.
Agriculture is a sector of the Nigerian economy, accounting for up to 35% of total employment in 2020. According to the FAO, agriculture remains the foundation of the Nigerian economy, providing livelihoods for most Nigerians and generating millions of jobs. Along with crude oil, Nigeria relies on the agricultural products it exports to generate most of its national revenue. The agricultural sector in Nigeria comprises four sub-sectors: crop production, livestock, forestry, and fishing.
The history of agriculture in India dates back to the Neolithic period. India ranks second worldwide in farm outputs. As per the Indian economic survey 2020 -21, agriculture employed more than 50% of the Indian workforce and contributed 20.2% to the country's GDP.
Roughly one-third of Iran's total surface area is suited for farmland, but because of poor soil and lack of adequate water distribution in many areas, most of it is not under cultivation. Only 12% of the total land area is under cultivation but less than one-third of the cultivated area is irrigated; the rest is devoted to dryland farming. Some 92 percent of agricultural products depend on water. The western and northwestern portions of the country have the most fertile soils. Iran's food security index stands at around 96 percent.
Agriculture in the Philippines is a major sector of the economy, ranking third among the sectors in 2022 behind only Services and Industry. Its outputs include staples like rice and corn, but also export crops such as coffee, cavendish banana, pineapple and pineapple products, coconut, sugar, and mango. The sector continues to face challenges, however, due to the pressures of a growing population. As of 2022, the sector employs 24% of the Filipino workforce and it accounted for 8.9% of the total GDP.
Agriculture employs the majority of Madagascar's population. Mainly involving smallholders, agriculture has seen different levels of state organisation, shifting from state control to a liberalized sector.
The southeast Asian country of Laos, with a landmass of 23.68 million hectares, has at least 5 million hectares of land suitable for cultivation. Seventeen percent of this land area is actually cultivated, less than 4 percent of the total area.
The role of agriculture in the Bolivian economy in the late 1980s expanded as the collapse of the tin industry forced the country to diversify its productive and export base. Agricultural production as a share of GDP was approximately 23 percent in 1987, compared with 30 percent in 1960 and a low of just under 17 percent in 1979. The recession of the 1980s, along with unfavorable weather conditions, particularly droughts and floods, hampered output. Agriculture employed about 46 percent of the country's labor force in 1987. Most production, with the exception of coca, focused on the domestic market and self-sufficiency in food. Agricultural exports accounted for only about 15 percent of total exports in the late 1980s, depending on weather conditions and commodity prices for agricultural goods, hydrocarbons, and minerals.
Throughout its history, agriculture in Paraguay has been the mainstay of the economy. This trend has continued today and in the late 1980s the agricultural sector generally accounted for 48 percent of the nation's employment, 23 percent of GDP, and 98 percent of export earnings. The sector comprised a strong food and cash crop base, a large livestock subsector including cattle ranching and beef production, and a vibrant timber industry.
Rice production in Vietnam in the Mekong and Red River deltas is important to the food supply in the country and national economy. Vietnam is one of the world's richest agricultural regions and is the second-largest exporter worldwide and the world's seventh-largest consumer of rice. The Mekong Delta is the heart of the rice-producing region of the country where water, boats, houses and markets coexist to produce a generous harvest of rice. Vietnam's land area of 33 million ha, has three ecosystems that dictate rice culture. These are the southern delta, the northern delta and the highlands of the north. The most prominent irrigated rice system is the Mekong Delta. Rice is a staple of the national diet and is seen as a "gift from God".
Agriculture in Panama is an important sector of the Panamanian economy. Major agricultural products include bananas, cocoa beans, coffee, coconuts, timber, beef, chicken, shrimp, corn, potatoes, rice, soybeans, and sugar cane.
National Innovations in Climate Resilient Agriculture (NICRA) was launched during February 2011 by the Indian Council of Agricultural Research (ICAR) with the funding from the Ministry of Agriculture, Government of India. The mega project has three major objectives of strategic research, technology demonstrations and capacity building. Assessment of the impact of climate change simultaneous with formulation of adaptive strategies is the prime approach under strategic research across all sectors of agriculture, dairying and fisheries.
Agriculture in Somalia is a major employment activity and is the largest economic sector in the country. It contributes more than 65% to the national GDP from domestic distribution and exports to other parts of the continent, the Middle East and Europe.
Agriculture in Liberia is a major sector of the country's economy worth 38.8% of GDP, employing more than 70% of the population and providing a valuable export for one of the world's least developed countries. Liberia has a climate favourable to farming, vast forests, and an abundance of water, yet low yields mean that over half of foodstuffs are imported, with net agricultural trade at -$73.12 million in 2010. This was dismissed as a "misconception" by Liberia's Minister of Agriculture.
Rice production in Myanmar accounts for approximately 43% of total agricultural production in the country, making it the seventh largest producer of rice in the world. Out of 67.6 million hectares of land, 12.8 million are used for cultivation. In 2019 alone, Myanmar accounted for 13,300 million metric tons of milled rice production.
