Agricultural Communication
Agricultural communication (or agricultural communications) is a field that focuses on communication about agriculture-related information among agricultural stakeholders and between agricultural and non-agricultural stakeholders. Agriculture is broadly defined in this discipline to include not only farming, but also food, fiber (e.g., cotton), animals, rural issues, and natural resources. Agricultural communication is done formally and informally by agricultural extension and is considered related to science communication. However, it has evolved into its own professional field. By definition, agricultural communicators are science communicators that deal exclusively with the diverse, applied science and business that is agriculture. An agricultural communicator is "expected to bring with him or her a level of specialized knowledge in the agricultural field that typically is not required of the mass communicator". Agricultural communication also addresses all subject areas related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farming
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: *Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and die ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Resources
Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife. Natural resources is a part of humanity's natural heritage or protected in nature reserves. Particular areas (such as the rainforest in Fatu-Hiva) often feature biodiversity and geodiversity in their ecosystems. Natural resources may be classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, air, as well as any living organism such as a fish, or it may be transformed by extractivist in ...

Agricultural Extension
Agricultural extension is the application of scientific research and new knowledge to agricultural practices through farmer education. The field of 'extension' now encompasses a wider range of communication and learning activities organized for rural people by educators from different disciplines, including agriculture, agricultural marketing, health, and business studies. Extension practitioners can be found throughout the world, usually working for government agencies. They are represented by several professional organizations, networks and extension journals. Agricultural extension agencies in developing countries receive large amounts of support from international development organizations such as the World Bank and the Food and Agriculture Organization of the United Nations. Extension terminology The use of the word 'extension' originated in england in 1866.Modern extension began in Dublin, Ireland in 1847 with Lord Clarendon's itinerant instructors during the great fami ...

Science Communication
Science communication is the practice of informing, educating, raising awareness of science-related topics, and increasing the sense of wonder about scientific discoveries and arguments. Science communicators and audiences are ambiguously defined and the expertise and level of science knowledge varies with each group. Two types of science communication are outward-facing or science outreach (typically conducted by professional scientists to non-expert audiences) and inward-facing or science "inreach" (expert to expert communication from similar or different scientific backgrounds). Examples of outreach include science journalism and science museums. Examples of inreach include scholarly communication and publication in scientific journals. But science communication is influenced by systemic inequalities that impact both inreach and outreach. Science communicators can use entertainment and persuasion including humour, storytelling and metaphors. Scientists can be trained in ...

Public Relations
Public relations (PR) is the practice of managing and disseminating information from an individual or an organization (such as a business, government agency, or a nonprofit organization) to the public in order to influence their perception. Public relations and publicity differ in that PR is controlled internally, whereas publicity is not controlled and contributed by external parties. Public relations may include an organization or individual gaining exposure to their audiences using topics of public interest and news items that do not require direct payment. The exposure mostly is media-based. This differentiates it from advertising as a form of marketing communications. Public relations aims to create or obtain coverage for clients for free, also known as earned media, rather than paying for marketing or advertising also known as paid media. But in the early 21st century, advertising is also a part of broader PR activities. An example of good public relations would be ge ...

Land-grant University
A land-grant university (also called land-grant college or land-grant institution) is an institution of higher education in the United States designated by a state to receive the benefits of the Morrill Land-Grant Acts, Morrill Acts of 1862 and 1890. Signed by Abraham Lincoln in 1862, the first Morrill Act began to fund educational institutions by granting federally controlled land (economics), land to the states for them to sell, to raise funds, to establish and Financial endowment, endow "land-grant" colleges. The mission of these institutions as set forth in the 1862 act is to focus on the teaching of practical agriculture, science, military science, and engineering—although "without excluding other scientific and classical studies"—as a response to the industrial revolution and changing social class. This mission was in contrast to the historic practice of higher education concentrating on a liberal arts curriculum. A 1994 expansion gave land-grant status to several trib ...

Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or "knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome. An organism that is generated through genetic engineering is considered to be genetically modified (GM) an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetically Modified Food
Genetically modified foods (GM foods), also known as genetically engineered foods (GE foods), or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits when compared to previous methods, such as selective breeding and mutation breeding. The discovery of DNA and the improvement of genetic technology in the 20th century played a crucial role in the development of transgenic technology. In 1988, genetically modified microbial enzymes were first approved for use in food manufacture. Recombinant rennet was used in few countries in the 1990s. Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its unsuccessful Flavr Savr delayed-ripening tomato.Weasel, Lisa H. 2009. ''Food Fray''.

Organic Food
Organic food, ecological food or biological food are food and drinks produced by methods complying with the standards of organic farming. Standards vary worldwide, but organic farming features practices that cycle resources, promote ecological balance, and conserve biodiversity. Organizations regulating organic products may restrict the use of certain pesticides and fertilizers in the farming methods used to produce such products. Organic foods typically are not processed using irradiation, industrial solvents, or synthetic food additives. In the 21st century, the European Union, the United States, Canada, Mexico, Japan, and many other countries require producers to obtain special certification to market their food as ''organic''. Although the produce of kitchen gardens may actually be organic, selling food with an organic label is regulated by governmental food safety authorities, such as the National Organic Program of the US Department of Agriculture (USDA) or European Commi ...

Bovine Spongiform Encephalopathy
Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is an incurable and invariably fatal neurodegenerative disease of cattle. Symptoms include abnormal behavior, trouble walking, and weight loss. Later in the course of the disease the cow becomes unable to function normally. There is conflicting information around the time between infection and onset of symptoms. In 2002, the WHO suggested it to be approximately four to five years. Time from onset of symptoms to death is generally weeks to months. Spread to humans is believed to result in variant Creutzfeldt–Jakob disease (vCJD). As of 2018, a total of 231 cases of vCJD had been reported globally. BSE is thought to be due to an infection by a misfolded protein, known as a prion. Cattle are believed to have been infected by being fed meat-and-bone meal (MBM) that contained either the remains of cattle who spontaneously developed the disease or scrapie-infected sheep products. The outbreak increased th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Proposition 2 (2008)
Proposition 2 was a California ballot proposition in that state's general election on November 4, 2008. It passed with 63% of the votes in favor and 37% against. Submitted to the Secretary of State as the Prevention of Farm Animal Cruelty Act, the initiative's name (as with others such as Proposition 8) was amended to officially be known as the Standards for Confining Farm Animals initiative. The official title of the statute enacted by the proposition is the Prevention of Farm Animal Cruelty Act. The proposition adds a chapter to Division 20 of the California Health and Safety Codebr> to prohibit the confinement of certain farm animals in a manner that does not allow them to turn around freely, lie down, stand up, and fully extend their limbs. The measure deals with three types of confinement: veal crates, battery cages, and sow gestation crates. Having been passed by the voters on November 4, 2008, the key portion of the statute became operative on January 1, 2015. Farming ope ...
