Agricultural change is built up of many replications of this novelty generation, selection and diffusion process, just as we’ve evolved through countless natural selection iterations. The main role of science in agriculture has been to help us generate novelties that allow us to produce more with less land and less effort.
Why do we need Science in developing sustainable agricultural systems?
Perhaps nowhere is this better demonstrated than in the need for science in developing sustainable agricultural systems. To understand why this is so it is first necessary to see that change in agricultural systems, like all technology change, is an evolutionary process.
How did the development of Technology improve agriculture?
With the improvement of technology man learnt to use tube wells and pumping sets. Development of these technologies for agriculture had other used, too. For example, primitive canals showed the way to modern network of canals which can irrigate vast areas of land and can make agriculture possible even in arid zones.
What do we need to make agriculture a science?
What is needed is a blending together of hard, reductionist science with ‘soft’ social science. What this means in practice for agriculture is that we begin with the selection and diffusion processes and pressures, that is the drivers of technology change, rather than with the novelties as we’ve done in the past.
What is the most important application of Science?
The most important application of science. Scientists often justify their work using these and similar arguments—currently linked to personal health and longer life expectancies, technological advancement, economic profits, and/or sustainability—in order to secure funding and gain social acceptance.
How has scientific research helped agriculture?
In agriculture, scientists actively seek to discover procedures that will increase livestock and crop yields, improve farmland pro- ductivity, reduce loss due to disease and insects, develop more effi- cient equipment, and increase overall food quality.
How has science and technology improved farming?
Advances in machinery have expanded the scale, speed, and productivity of farm equipment, leading to more efficient cultivation of more land. Seed, irrigation, and fertilizers also have vastly improved, helping farmers increase yields.
What is the big impact of science in agriculture?
Science made agriculture a business, not a relatively low-paying way of life. Science saved the American farmer from agrarian peasantry, and gave his children the opportunity of higher education and so the right and freedom to compete in any occupation.
How can science help farmers?
For centuries, humans have used science to improve soil productivity and crop yields. The last century has seen huge changes in farming practices. For example, the use of fertilisers and irrigation along with improved plant and animal breeding have made it possible to increase the amount of product a farm can produce.
How information technology helps the agriculture?
Some of the roles of Information technology in the agricultural sector include : Improved productivity. Farmers need information on latest varieties, changing weather patterns, crop production techniques and improved agronomic practices for them to produce.
How has science improved agriculture in India?
New farming irrigation methods such as drip irrigation, stronger and more resistant pesticides, more efficient fertilizers, and newly developed seeds helped in proficient crop growth. As a result of such new improvements in agricultural methods, India experienced drastic increases in crop production.
How has science and technology helped in food production?
Science, technology, and innovation can play a critical role in producing more food by creating plant varieties with improved traits, as well as optimizing the inputs needed to make agriculture more productive.
What are the application of science and technology in the food industry?
What is Food Technology? Food technology is the application of food science to the selection, preservation, processing, packaging, distribution, and use of safe food. Related fields include analytical chemistry, biotechnology, engineering, nutrition, quality control, and food safety management.
What is the impact of science and technology on agriculture?
Importance of Agricultural Technology Higher crop productivity. Decreased use of water, fertilizer, and pesticides, which in turn keeps food prices down. Reduced impact on natural ecosystems. Less runoff of chemicals into rivers and groundwater.
How is science related to agriculture?
Agricultural science will help countries adjust to healthier methods of food production. Scientists are developing new high-yield varieties of crops that require fewer fertilizers or pesticides. Such crops reduce the need for using costly chemicals and trade.
Why did farmers not know the consequences of their actions?
Farmers did not know the consequences because they were used to operating on the scale of their own fields, not to thinking about what might happen over millions of hectares. And the research and extension systems that were encouraging them to adopt did not know the consequences either.
Why are humans a force of nature?
The report, prepared by the United Nations, the World Bank and the World Resources Institute, shows that humans have become a major force of nature, largely because of the success of science-based technologies in extracting the earth’s resources without proper concern for the environmental consequences. Science, though, has a crucial role …
What is biotechnology?
Biotechnology is a suit of tools that allows plant breeders to introduce a greater array of novelty into their plant varieties, and select which work, much faster than they could using conventional plant breeding techniques. There is nothing inherently evil or Frankenstein-like about genetically modified plants.
Why do we need to meet the Ecochallenge?
To meet the ecochallenge science needs to help contribute to a framework that guides our selection decisions so that we don’t all grow one rice variety or cut down the rainforest with devastating consequences for human development and the welfare of all species.
What was the main source of water for irrigating primitive man’s fields?
Development in irrigation rainfall was the main source of water for irrigating primitive man’s fields. He learnt to store this water in ditches and reservoirs that he made. He also learnt to divert water to his fields from ponds and rivers. This gave him the idea of canals.
How did man learn to craft new things?
It is clear that as man’s knowledge of nature and its laws increased, i.e., as science developed, so did man’s ability to craft new things for his use, For example, man first learnt how to make fore and then he used fore to cook, to bake pottery, to extract and purify metals using fore. ADVERTISEMENTS:
What did man use domesticated animals for?
Now man could same these animals, feed them and use them for drawing carts, ploughing and grinding, hauling logs, etc. Thus domesticated animals became a resource. Take the case of clay. Man had no use for it till advancement in technology allowed him to make pottery, bricks, etc.
How did man irrigate the land?
To irrigate the land, man developed several tools like water pulley and water-wheel. He used animals to operated water pulleys. With the improvement of technology man learnt to use tube wells and pumping sets. Development of these technologies for agriculture had other used, too.
What animals did the Romans use to thresh grains?
For this he drafted ox, buffalo, horse, camel, etc. For threshing of grains too, these animals were used. The use of animals on farm set free many men to do other works. The use of animals for other purposes like pulling carts, etc., also increased.
What did the Stone Age people do?
In the New Stone Age, man discovered that he could grow his own crops . In the beginning he used primitive tools and grew basic crops like wheat and some fruit trees.
What would happen if the utilitarian view of science as an economic tool prevailed?
If the utilitarian view of science as an economic tool prevails, basic research will suffer. Dismantling the current science research infrastructure, which has taken centuries to build and is based on free enquiry, would have catastrophic consequences for humanity.
Why do scientists justify their work?
Scientists often justify their work using these and similar arguments—currently linked to personal health and longer life expectancies, technological advancement, economic profits, and/or sustainability—in order to secure funding and gain social acceptance.
What is the improvement of human culture and society?
The improvement of human culture and society relies on more diffuse structural and functional patterns. In the case of science, its diffusion to the general public is commonly called the popularisation of science and can involve scientists themselves, rather than journalists and other communicators.
What is a classic example of a discipline that was virtually absent from school textbooks a couple of generations ago
A classic example is molecular biology; a discipline that was virtually absent from school textbooks a couple of generations ago. The deliberate and consistent addition of new scientific knowledge to enhance education might seem an obvious application of science, but it is often ignored.
