Since cereals that absorbed extra nitrogen would typically lodge (fall over) before harvest, semi-dwarfing genes were bred into their genomes. The drought affected the production of livestock and field crops such as wheat, corn, and soybean production in the Great Plains and Midwest and accounted for $14.5 billion in loss payments by the federal crop insurance program. Nitrogen compounds from the Midwest, for example, travel down the Mississippi to degrade coastal fisheries in the Gulf of Mexico, causing so-called oceanic dead zones. The perennial grasses form a living mulch understory to the grain crop, eliminating the need to plant cover crops after harvest.

Weather based crop insurance in India Policy Research Working Paper, World Bank. www.elibrary.worldbank.org/doi/pdf/10. Some of these act by interfering with the growth of the weed and are often based on plant hormones. It is characterized by a low fallow ratio, higher use of inputs such as capital and labour, and higher crop yields per unit land area.[1]. "[62], Industrial agriculture uses huge amounts of water, energy,[63] and industrial chemicals, increasing pollution in the arable land, usable water, and atmosphere. This volume presents the concepts and operational means for reorienting agricultural efforts towards these more environmentally friendly and socially desirable approaches in the developed as well as developing world. The Green Revolution transformed farming in many developing countries. [65], But other adverse effects show up within agricultural production systemsfor example, the rapidly developing resistance among pests renders herbicides and insecticides increasingly ineffective. Intensive agriculture, also known as intensive farming (as opposed to extensive farming) and 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. ), Intensive monoculture increases the risk of failures due to pests, adverse weather and disease. For example, in 2012, severe drought impacted 80 percent of agricultural land in the United States, causing more than two-thirds of its counties to be declared disaster areas. The primary direct economic impact of drought in the agricultural sector is crop failure and pasture losses. The challenges and issues of industrial agriculture for society, for the sector, and for animal rights, include the costs and benefits of both current practices and proposed changes to those practices. There are concerns over the sustainability of industrial agriculture, and the environmental effects of fertilizers and pesticides, which has given rise to the organic movement[18] and has built a market for sustainable intensive farming, as well as funding for the development of appropriate technology. The United States Environmental Protection Agency identified certain animal feeding operations, along with many other types of industry, as "point source" groundwater polluters. Conservation Agriculture is a farming system that promotes minimum soil disturbance (i.e. Species diversificationthrough varied crop sequences and associations involving at least three different crops. Forms that rely heavily on industrial methods are often called industrial agriculture, which is characterised by innovations designed to increase yield. Dammed rivers creating reservoirs store water for irrigation and other uses over large areas. A traditional component of crop rotation is the replenishment of nitrogen through the use of legumes and green manure in sequence with cereals and other crops. However, the advantage is lost for the progeny of the F1 hybrids, meaning seeds for annual crops need to be purchased every season, thus increasing costs and profits for farmers. [50], Aquaculture is the cultivation of the natural products of water (fish, shellfish, algae, seaweed, and other aquatic organisms). In Peru, the Inca made use of otherwise unusable slopes by building drystone walls to create terraces known as Andns. Historians cited enclosure, mechanization, four-field crop rotation, and selective breeding as the most important innovations. This in turn contributed to unprecedented population growth, freeing up a significant percentage of the workforce, and thereby helped enable the Industrial Revolution. crop yields and bolster resilience to drought and extreme weather an intensification of herbicide use with new crops genetically engineered to withstand hazardous herbicides dicamba and 2,4-D. A 2018 survey system. Learn more about the threats facing bees, including habitat loss, climate change, pesticides, pests and disease, and invasive species.

World Dev 87:139151 de Abreu LS, In 2015, farms contributed, For example, in 2012, severe drought impacted 80 percent of agricultural land in the United States, causing more than two-thirds of its counties to be declared disaster areas. Animal rights and animal welfare activists have charged that intensive animal rearing is cruel to animals. An official website of the United States government. Smaller areas sometimes use irrigation ponds or groundwater. Resting grazed lands allows the vegetation to renew energy reserves, rebuild shoot systems, and deepen root systems, resulting in long-term maximum biomass production. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project.

Journal of Applied Ecology 40 (6): 98493. doi:10.1111/j.1365-2664.2003.00856.x. Vertical farming is intensive crop production on a large scale in urban centers, in multi-story, artificially-lit structures, for the production of low-calorie foods like herbs, microgreens, and lettuce. With the increased productivity of rotational systems, the animals may need less supplemental feed than in continuous grazing systems. [70] Agricultural monoculture can entail social and economic risks. They require large water quantities for irrigation, much of it from flooding. The impacts of climate change on crop yield can already be detected in observed data (Lobell et al., 2011).Climate impact studies on crops predominate, but impacts on fisheries and livestock production are no less serious (Creighton et al., 2015, Herrero et al., 2015). [43], In the 1970s, scientists created high-yielding varieties of maize, wheat, and rice. A lagoon that burst in 1995 released 25 million gallons of nitrous sludge in North Carolina's New River. [68][69], A study for the U.S. Office of Technology Assessment concluded that regarding industrial agriculture, there is a "negative relationship between the trend toward increasing farm size and the social conditions in rural communities" on a "statistical level". Most specialty crops (such as fruits, vegetables, tree nuts, and medicinal herbs) are more vulnerable to drought than field crops and have a higher value per unit of land/water. NIDIS is a multi-agency partnership that coordinates drought monitoring, forecasting, planning, and information at national, state, and local levels across the country. Intercropping can increase yields or reduce inputs and thus represents (potentially sustainable) agricultural intensification. The depletion of water availability in soils causes significant declines in crops and livestock productivity. [14], The discovery of vitamins and their role in nutrition, in the first two decades of the 20th century, led to vitamin supplements, which in the 1920s allowed some livestock to be raised indoors, reducing their exposure to adverse natural elements. [16][citation needed] Developments in logistics and refrigeration as well as processing technology made long-distance distribution feasible. [6] The earliest rice cultivation there may have used dry-fields instead of paddies.

(2012) Increasing cropping system diversity balances productivity, profitability and no tillage), maintenance of a permanent soil cover, and diversification of plant species. In 1909, the Haber-Bosch method to synthesize ammonium nitrate was first demonstrated. These methods increase the yields of food and fiber per acre as compared to extensive animal husbandry; concentrated feed is brought to seldom-moved animals, or with rotational grazing the animals are repeatedly moved to fresh forage.[4][5]. NIDIS partners with the USDA Climate Hubs across the nation to support agricultural producers and ranchers with early information of drought onset and intensification; assessing the impacts of drought on the sector and the economy; and training and raising awareness among farmers and ranchers of how drought is depicted in the U.S. Drought Monitor, which determines federal assistance for producers.
