What is the history of agricultural biotechnology?
This chapter presents the history of agricultural biotechnology. Throughout the history of agriculture, biotechnological processes have been used in the creation of agricultural products. Food and agriculture are biological by nature and are the result of biological applications.
How did biotechnology start in the United States?
At the beginning of the twentieth century, industry and agriculture started to incorporate biotechnology. The growing automobile industry, for example, used fermentation processes to produce acetone and paint solvents.
How has biotechnology been used in everyday life?
Humans have used biotechnology since the dawn of civilization. Egyptians used yeasts to bake leavened bread, the Chinese developed fermentation techniques for brewing and cheese making, and the Aztecs used Spirulina algae to make cakes. Today, when most people think of biotechnology, they probably think of recombinant DNA.
Is biotechnology in agriculture more effective than agrochemical?
Arguably the use of biotechnology in agriculture is deemed to be more effective than that of agrochemical. The latter is believed to be responsible for causing environmental distress and is also somewhat unfeasible for farmers.
When was biotechnology first used?
1919The term biotechnology was used for the first time by Karl Erkey, a Hungarian Engineer, in 1919.
Who discovered agricultural biotechnology?
Two scientists, James Watson and Francis Crick made this discovery (Pray 2008), considered to be one of the most significant scientific works in biology, largely through synthesis of the work of other scientists.
How long has biotechnology being used in agriculture?
The first food product produced through biotechnology was sold in 1990, and by 2003, 7 million farmers were utilizing biotech crops. More than 85% of these farmers were located in developing countries.
How is biotechnology used in agriculture?
How is Agricultural Biotechnology being used? Biotechnology provides farmers with tools that can make production cheaper and more manageable. For example, some biotechnology crops can be engineered to tolerate specific herbicides, which make weed control simpler and more efficient.
How has biotechnology improved farming and modern agriculture?
Biotechnology allows farmers to grow more food on less land using farming practices that are environmentally sustainable. Through biotechnology: Seeds yield more per acre, plants naturally resist specific insect pests and diseases, and farming techniques improve soil conservation.

How has biotechnology changed agriculture in the United States?
With improved weed control, plants are healthier and do not have to compete for nutrients in the soil. Healthier plants result in improved yield. Environmental Benefits: Thanks to biotechnology, farmers have adopted no- and reduced-tillage systems which utilize herbicidal weed control rather than plowing.
How did agriculture evolve?
Agricultural communities developed approximately 10,000 years ago when humans began to domesticate plants and animals. By establishing domesticity, families and larger groups were able to build communities and transition from a nomadic hunter-gatherer lifestyle dependent on foraging and hunting for survival.

Since then, the U.S. Food and Drug Administration (FDA), U.S. Environmental Protection Agency (EPA), and U.S. Department of Agriculture (USDA) have worked together to ensure that crops produced through genetic engineering are safe for people, animals, and the environment. Despite there being a wide range of foods—GMO and non-GMO—available …
What is agricultural biotechnology?
Agricultural Biotechnology is the use of new scientific techniques based on our understanding of DNA to improve crops and livestock that are not possible with conventional breeding alone. This can be achieved in part by modern molecular plant breeding techniques such as marker-assisted selection (MAS).
How does biotechnology affect agriculture?
Agricultural biotechnology delivers biomass for food, feed, genetic modifications, and molecular tools to enhance the plant breeding potential, resulting in increased food supplies, farm income, and reduced damage to ecology and environment.
What are some examples of biotechnology?
For example, one of the most important products generated through agricultural biotechnology has been the introduction of transgenic crop plants which confer herbicide tolerance, in such a way that herbicides can be sprayed on transgenic crops without causing damage while detouring the growth of neighboring weeds.
How are public attitudes toward agricultural biotechnology influenced by the social environment?
They are largely influenced by the social environment and the mass media, particularly when the issue at stake is characterized by weak involvement and lack of direct experience. This situation applies in particular to Europe, where the de facto ban on the cultivation of GMOs in most European countries, the lack of concrete experience with labeled GM food in supermarkets and the absence of public initiatives to render a practical experience with GMOs mandatory in high school education have led to rather heteronomous views on the technology. The lack of experience with GMOs has increased the influence of stakeholders in politics in the framing of the debate. By opposing GMOs they try to assure the public of their good motives and thus gaining public trust as guardians of food safety, the environment, and social values. The situation in North America in general and the United States in particular is different since farmers, consumers, and high school students mostly have made a concrete experience with the technology and this makes it more difficult for advocacy groups to portray themselves as the voices that represent the interests of consumers and producers. In the developing world there are countries in Latin America and Asia that have embraced the technology without much public debate. However, the continent that has so far been as reluctant as Europe to embrace the technology is Africa. Apart from South Africa and a few other countries that approved of the commercial release of Bt cotton, the continent remains largely GMO free. This is however not due to genuine domestic opposition to the technology but the pressure from Europe as the largest donor to African governments and the largest importer of agricultural products from Africa.
Why do insects die?
The insects soon die as a result of pores which are created in the gut cell membrane. The first generation of biotechnology crops focused on agronomic input traits that helped farmers; however, their value was not clear to the general consumer who is disconnected to the demands of farming.
