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 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.
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.
Integrated pest management (IPM), also known as integrated pest control (IPC) that integrates both chemical and non-chemical practices for economic control of pests. The UN's Food and Agriculture Organization defines IPM as "the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human health and the environment. IPM emphasizes the growth of a healthy crop with the least possible disruption to agro-ecosystems and encourages natural pest control mechanisms." Entomologists and ecologists have urged the adoption of IPM pest control since the 1970s. IPM is a safer pest control framework than reliance on the use of chemical pesticides, mitigating risks such as: insecticide-induced resurgence, pesticide resistance and (especially food) crop residues.
In agriculture, polyculture is the practice of growing more than one crop species together in the same place at the same time, in contrast to monoculture, which had become the dominant approach in developed countries by 1950. Traditional examples include the intercropping of the Three Sisters, namely maize, beans, and squashes, by indigenous peoples of Central and North America, the rice-fish systems of Asia, and the complex mixed cropping systems of Nigeria.
An agrochemical or agrichemical, a contraction of agricultural chemical, is a chemical product used in industrial agriculture. Agrichemical refers to biocides and synthetic fertilizers. It may also include hormones and other chemical growth agents.
Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. For example, cereal crops like maize or sorghum are often infested by stem borers. Grasses planted around the perimeter of the crop attract and trap the pests, whereas other plants, like Desmodium, planted between the rows of maize, repel the pests and control the parasitic plant Striga. Push–pull technology was developed at the International Centre of Insect Physiology and Ecology (ICIPE) in Kenya in collaboration with Rothamsted Research, UK. and national partners. This technology has been taught to smallholder farmers through collaborations with universities, NGOs and national research organizations.
Organic cotton is generally defined as cotton that is grown organically in subtropical countries such as India, Turkey, China, and parts of the USA from non-genetically modified plants, and without the use of any synthetic agricultural chemicals such as fertilizers or pesticides aside from the ones allowed by the certified organic labeling. Its production is supposed to promote and enhance biodiversity and biological cycles. In the United States, cotton plantations must also meet the requirements enforced by the National Organic Program (NOP) from the USDA in order to be considered organic. This institution determines the allowed practices for pest control, growing, fertilizing, and handling of organic crops.
The Philippines' National Food Authority, is an agency of the Philippine government under the Department of Agriculture responsible for ensuring the food security of the Philippines and the stability of supply and price of rice, the Philippines' staple grain.
The Philippines' Fertilizer and Pesticide Authority, is a technical regulatory agency under the Department of Agriculture. The agency is responsible for assuring adequate supply of fertilizer and pesticide at reasonable prices; rationalizing the manufacture and marketing of fertilizer; protecting the public from the risks of the inherent use of pesticides; and educating the agricultural sector in the use of these inputs.
Industrial agriculture is a form of modern farming that refers to the industrialized production of crops and animals and animal products like eggs or milk. The methods of industrial agriculture include innovation in agricultural machinery and farming methods, genetic technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, the application of patent protection to genetic information, and global trade. These methods are widespread in developed nations and increasingly prevalent worldwide. Most of the meat, dairy, eggs, fruits and vegetables available in supermarkets are produced in this way.
Intensive crop farming is a modern industrialized form of crop farming. Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade. These methods are widespread in developed nations.
The Green Revolution was a period that began in the 1960s during which agriculture in India was converted into a modern industrial system by the adoption of technology, such as the use of high yielding variety (HYV) seeds, mechanized farm tools, irrigation facilities, pesticides, and fertilizers. Mainly led by agricultural scientist M. S. Swaminathan in India, this period was part of the larger Green Revolution endeavor initiated by Norman Borlaug, which leveraged agricultural research and technology to increase agricultural productivity in the developing world. Varieties or strains of crops can be selected by breeding for various useful characteristics such as disease resistance, response to fertilizers, product quality and high yields.
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.
Rice production in Indonesia is an important part of the national economy. Indonesia is the third-largest producer of rice in the world.
Rice production in China is the amount of rice planted, grown, and harvested for consumption in the mainland of China.
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.
Striga hermonthica, commonly known as purple witchweed or giant witchweed, is a hemiparasitic plant that belongs to the family Orobanchaceae. It is devastating to major crops such as sorghum and rice. In sub-Saharan Africa, apart from sorghum and rice, it also infests maize, pearl millet, and sugar cane.
The 21-year period of Philippine economic history during Ferdinand Marcos’ regime – from his election in 1965 until he was ousted by the People Power Revolution in 1986 – was a period of significant economic lows.
A rice-fish system is a rice polyculture, a practice that integrates rice agriculture with aquaculture, most commonly with freshwater fish. It is based on a mutually beneficial relationship between rice and fish in the same agroecosystem. The system was recognized by the FAO in 2002 as one of the first Globally Important Agricultural Heritage Systems.
