What is traditional agriculture?

Traditional agricultural systems, sometimes termed subsistence agriculture, which feed most of the poorest people in the world. These systems are of interest as they sometimes retain a level of integration with natural ecological systems greater than that of industrial agriculture, which may be more sustainable than some modern agricultural systems.

Which countries are responsible for food production?

Food production and demand on a global basis, with special attention paid to the major producers, such as China, India, Brazil, the US and the EU.

When did the agricultural revolution start?

In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887 , which used the term “agricultural science”. The Hatch Act was driven by farmers’ interest in knowing the constituents of early artificial fertilizer.

Who was the first scientist to use gypsum as a fertilizer?

In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulphate) as a fertilizer. In 1843, John Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research Station in England, some of which are still running as of 2018.

What is agricultural science?

Agricultural sciences, sciences dealing with food and fibre production and processing. They include the technologies of soil cultivation, crop cultivation and harvesting, animal production, and the processing of plant and animal products for human consumption and use. Food is the most basic human need.

How does agricultural technology affect the world?

From a global perspective, the international flow of agricultural technology allows for the increase of agricultural productivity in developed and developing countries alike. From 1965 to 1985, for example, world trade in grains tripled, as did net exports from the United States. In 1995 the total value of U.S. agricultural exports exceeded $56 billion, and it increased to more than $138 billion by 2017, making U.S. agriculture heavily dependent upon international markets. Similarly, China is both a major importer and exporter of agricultural products and is an important driver of global crop production.

What did the USDA do in the early 21st century?

In the early 21st century the USDA had a number of grants to promote agricultural education at all grade levels, and many major universities, both private and public, continued to offer programs in agricultural sciences.

What is the most basic human need?

Food is the most basic human need. The domestication and cultivation of plants and animals beginning more than 11,500 years ago were aimed at ensuring that this need was met, and then as now these activities also fit with the relentless human drive to understand and control Earth’s biosphere. Over the last century and a half, many of the world’s political leaders have recognized what India’s Jawaharlal Nehru did, that “most things except agriculture can wait.” Scientific methods have been applied widely, and the results have revolutionized agricultural production. Under the conditions of prescientific agriculture, in a good harvest year, six people can produce barely enough food for themselves and four others. Advanced technologies have made it possible for one farmer in the United States, for example, to produce food for more than 100 people. The farmer has been enabled to increase yields per acre and per animal; reduce losses from diseases, pests, and spoilage; and augment net production by improved processing methods.

How did agricultural research help the economy?

Until the 1930s, the benefits of agricultural research derived mostly from labour-saving inventions, like the cotton gin. Once the yield potentials of the major economic crops were increased through agricultural research, however, crop production per acre increased dramatically. Between 1940 and 1980 in the United States, for example, per-acre yields of corn tripled, those of wheat and soybeans doubled, and farm output per hour of farm work increased almost 10-fold as capital was substituted for labour. New techniques of food preservation made it possible to transport them over greater distances, in turn facilitating adjustments among locations of production and consumption, with further benefits to production efficiency.

Who was the first scientist to study agriculture?

The scientific approach was inaugurated in 1840 by Justus von Liebig of Darmstadt, Germany. His classic work, Die organische Chemie in ihrer Anwendung auf Agrikulturchemie und Physiologie (1840; Organic Chemistry in Its Applications to Agriculture and Physiology ), launched the systematic development of the agricultural sciences. In Europe, a system of agricultural education soon developed that comprised secondary and postsecondary instruction. The old empirical-training centres were replaced by agricultural schools throughout Europe and North America. Under Liebig’s continuing influence, academic agriculture came to concentrate on the natural sciences.

Did the agricultural sciences gain a place in the academic structure?
