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.
Roughly one-third of Iran's total surface area is suitable for farmland, but because of poor soil and a 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 is one of the dominant parts of Senegal's economy, even though Senegal lies within the drought-prone Sahel region. As only about 5% of the land is irrigated, Senegal continues to rely on rain-fed agriculture. Agriculture occupies about 75% of the workforce. Despite a relatively wide variety of agricultural production, the majority of farmers produce for subsistence needs. Millet, rice, corn, and sorghum are the primary food crops grown in Senegal. Production is subject to drought and threats of pests such as locusts, birds, fruit flies, and white flies. Moreover, the effects of climate change in Senegal are expected to severely harm the agricultural economy due to extreme weather such as drought, as well as increased temperatures.
Agriculture's share of GDP has declined in recent years, falling from 42% in 1989, to 26% in 1999. In 2023, agriculture and forestry accounted for about 12% of Vietnam's gross domestic product (GDP). However, agricultural employment was much higher than agriculture's share of GDP; in 2005, approximately 60 percent of the employed labor force was engaged in agriculture, forestry, and fishing. Agricultural products accounted for 30 percent of exports in 2005. The relaxation of the state monopoly on rice exports transformed the country into the world's second or third largest rice exporter. Other cash crops are coffee, cotton, peanuts, rubber, sugarcane, and tea.
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.
Agriculture is considered the backbone of Pakistan's economy, which relies heavily on its major crops. Pakistan's principal natural resources are arable land and water. Agriculture accounts for about 18.9% of Pakistan's GDP and employs about 42.3% of the labour force. The most agricultural province is Punjab where wheat & cotton are the most grown. Mango orchards are mostly found in Sindh and Punjab provinces, making it the world's fourth largest producer of mangoes.
Agriculture in Ethiopia is the foundation of the country's economy, accounting for half of gross domestic product (GDP), 83.9% of exports, and 80% of total employment.
Agriculture continued to be the mainstay of the economy of Haiti in the late 1980s; it employed approximately 66 percent of the labor force and accounted for about 35 percent of GDP and for 24 percent of exports in 1987. The role of agriculture in the economy has declined severely since the 1950s, when the sector employed 80 percent of the labor force, represented 50 percent of GDP, and contributed 90 percent of exports. Many factors have contributed to this decline. Some of the major ones included the continuing fragmentation of landholdings, low levels of agricultural technology, migration out of rural areas, insecure land tenure, a lack of capital investment, high commodity taxes, the low productivity of undernourished animals, plant diseases, and inadequate infrastructure. Neither the government nor the private sector invested much in rural ventures; in FY 1989 only 5 percent of the national budget went to the Ministry of Agriculture, Natural Resources, and Rural Development. As Haiti entered the 1990s, however, the main challenge to agriculture was not economic, but ecological. Extreme deforestation, soil erosion, droughts, flooding, and the ravages of other natural disasters had all led to a critical environmental situation.
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.
Benin is predominantly a rural society, and agriculture in Benin supports more than 70% of the population. Agriculture contributes around 35% of the country's gross domestic product (GDP) and 80% of export income. While the Government of Benin (GOB) aims to diversify its agricultural production, Benin remains underdeveloped, and its economy is underpinned by subsistence agriculture. Approximately 93% of total agricultural production goes into food production. The proportion of the population living in poverty is about 35.2%, with more rural households in poverty (38.4%) than urban households (29.8%). 36% of households depend solely upon agricultural (crop) production for income, and another 30% depend on crop production, livestock, or fishing for income.
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.
Agriculture in Jordan contributed substantially to the economy at the time of Jordan's independence, but it subsequently suffered a decades-long steady decline. In the early 1950s, agriculture constituted almost 40 percent of GNP; on the eve of the Six-Day War, it was 17 percent.
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.
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.
Agriculture in Spain is important to the national economy. The primary sector activities accounting for agriculture, husbandry, fishing and silviculture represented a 2.7% of the Spanish GDP in 2017, with an additional 2.5% represented by the agrofood industry.
Despite the crisis in Syria, agriculture remains a key part of the economy. The sector still accounts for an estimated 26 percent of gross domestic product (GDP) and represents a critical safety net for the 6.7 million Syrians – including those internally displaced – who still remain in rural areas. However, agriculture and the livelihoods that depend on it have suffered massive losses . Today, food production is at a record low and around half the population remaining in Syria are unable to meet their daily food needs.
Moldova is an agrarian-industrial state, with agricultural land occupying 2,499,000 hectares in a total area of 3,384,600 hectares. It is estimated that 1,810,500 of these hectares are arable. Moldova is located in Eastern Europe, and is landlocked, bordering Romania and Ukraine. Moldova's agricultural sector benefits from a geographical proximity to large markets, namely the European Union. As a share of GDP, agriculture has declined from 56% in 1995 to 13.8% in 2013. Data from 2015 estimated that agriculture accounted for 12% of Moldova's GDP. Agriculture as a sector is export-oriented, with the composition of Moldova's total exports containing agriculture and the agri-food sector as a main component. 70% of agri-food exports in 2012 included beverages, edible fruits and nuts, oilseeds, vegetable preparations and cereals. Here, fruits, vegetables and nuts were attributed to 33% of Moldova's exports for 2011–2013. Moldova is also one of the top ten apple exporters in the world. However, because of the long-term emphasis on fruit, vegetables are often imported.
Farming systems in India are strategically utilized, according to the locations where they are most suitable. The farming systems that significantly contribute to the agriculture of India are subsistence farming, organic farming, industrial farming. Regions throughout India differ in types of farming they use; some are based on horticulture, ley farming, agroforestry, and many more. Due to India's geographical location, certain parts experience different climates, thus affecting each region's agricultural productivity differently. India is very dependent on its monsoon cycle for large crop yields. India's agriculture has an extensive background which goes back to at least 9 thousand years. In India, in the alluvial plains of the Indus River in Pakistan, the old cities of Mohenjo-Daro and Harappa experienced an apparent establishment of an organized farming urban culture. That society, known as the Harappan or Indus civilization, flourished until shortly after 4000 BP; it was much more comprehensive than those of Egypt or Babylonia and appeared earlier than analogous societies in northern China. Currently, the country holds the second position in agricultural production in the world. In 2007, agriculture and other industries made up more than 16% of India's GDP. Despite the steady decline in agriculture's contribution to the country's GDP, agriculture is the biggest industry in the country and plays a key role in the socio-economic growth of the country. India is the second-largest producer of wheat, rice, cotton, sugarcane, silk, groundnuts, and dozens more. It is also the second biggest harvester of vegetables and fruit, representing 8.6% and 10.9% of overall production, respectively. The major fruits produced by India are mangoes, papayas, sapota, and bananas. India also has the biggest number of livestock in the world, holding 281 million. In 2008, the country housed the second largest number of cattle in the world with 175 million.
