What impact did the Green Revolution have on agriculture?
The green revolution led to high productivity of crops through adapted measures, such as (1) increased area under farming, (2) double-cropping, which includes planting two crops rather than one, annually, (3) adoption of HYV of seeds, (4) highly increased use of inorganic fertilizers and pesticides, (5) improved ...
Definition of green revolution
: the great increase in production of food grains (such as rice and wheat) due to the introduction of high-yielding varieties, to the use of pesticides, and to better management techniques.
After the green revolution, the production of cereal crops tripled with only a 30% increase in the land area cultivated. This came true all over the world, with a few exceptions. In addition, there were significant impacts on poverty reduction and lower food prices.
green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. Its early dramatic successes were in Mexico and the Indian subcontinent.
Ray Offenheiser: The Green Revolution was the emergence of new varieties of crops, specifically wheat and rice varietals, that were able to double if not triple production of those crops in two countries.
Green Revolution refers to the substantial increase in production of foodgrains resulting from the use of High Yielding Varieties (HYVs) of seeds and the increased use of fertilisers, pesticides and irrigation facilities.
Increased yield and improved varieties of wheat and rice were introduced in India. Examples of improved varieties of wheat: Sonalika and Kalyan Sona. Examples of improved varieties of rice: Jaya and Ratna.
The Green Revolution, or the Third Agricultural Revolution (after the Neolithic Revolution and the British Agricultural Revolution), is the set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production in parts of the world, beginning most markedly in ...
Answer: By using modern farming methods, Indian farmers are able to produce much greater amount of grains on a single plant. There is a large increase in the production of wheat. Using these methods, the farmers have greater amounts of surplus wheat to sell in the markets.
Green Revolution in India
Major milestones in this undertaking were the development of high-yielding varieties of wheat. The Green revolution is revolutionary in character due to the introduction of new technology, new ideas, the new application of inputs like HYV seeds, fertilizers, irrigation water, pesticides, etc.
What are the positive and negative effect of Green Revolution?
Reduced production costs and resulted in cheaper food prices. Had a few side effects on health. The agricultural industry was able to produce much larger quantities of food. The use of chemical fertilizers, synthetic herbicides increased environmental and soil pollution.
Grade 9. It is important to develop irrigation facilities as it ensures the following: Well-Developed irrigation facilities reduce the dependence of farmers on monsoons and ensure regular supply of water. Irrigation also facilitates the construction of dams that help in generating electricity.
The application of concentrated nitrogen to farm fields increased production even over the yields that had been achieved using guano and nitrate, causing a global explosion of crop yields known as the Green Revolution.
Abstract. The Green Revolution in India was initiated in the 1960s by introducing high-yielding varieties of rice and wheat to increase food production in order to alleviate hunger and poverty.
Solution : (i) Loss of soil fertility due to increased use of chemical fertilizers. <br> (ii) Continuous use of groundwater for tubewell irrigation has reduced the water table below the ground. <br> (iii) The chemical fertilizers, casily soluble in water, can dissolve in the groundwater and pollute it.
Overall, these efforts benefited virtually all consumers in the world and the poor relatively more so, because they spend a greater share of their income on food (29).
The Neolithic Revolution—also referred to as the Agricultural Revolution—is thought to have begun about 12,000 years ago. It coincided with the end of the last ice age and the beginning of the current geological epoch, the Holocene.
The different techniques that promoted the increase in agricultural productivity was called The Green Revolution, also Third Agricultural Revolution, and was based mainly on the use of varieties of high-yielding seeds, cultivated in large areas (monoculture), and the use of large amounts of fertilizers, phytoregulators ...
Poor infrastructure, high transport costs, limited investment in irrigation, and pricing and marketing policies that penalized farmers made the Green Revolution technologies too expensive or inappropriate for much of Africa.
Green Revolution is associated with agricultural production. It is the period when agriculture of the country was converted into an industrial system due to the adoption of modern methods and techniques like the use of high yielding variety seeds, tractors, irrigation facilities, pesticides, and fertilizers.
Who started Green Revolution?
M. S. Swaminathan, the main architect or the Father of the Green Revolution in India.
Yes it is important for India to be Self-sufficient in food grain production because, India is an agricultural country. It has the resources required for the production of food grains in abundance. It is necessary to exploit these resources to the full extent to meet the requirement of food grains in our country.
Food security is defined by the Food and Agriculture Organization (FAO) as: when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life.
Some of the plants grown from HYV seeds are maize, wheat and rice. Hyv seeds are modern variety seeds and various new characteristics are found in these plants. Some plants grown from traditional seeds are wheat and maize.
Higher-yielding seeds (HYV) refer to those that produce large quantities of crops, including rice and wheat. Regular water supply, the highest use of fertilisers, and the application of pesticides with a precise proportion are essential to using these seeds.
Modern farming methods imply use of chemical fertilisers and artificial irrigation. Excessive use of chemical fertilisers has led to loss of soil fertility in the following manner : (a) The chemical fertilisers and pesticides destroy the microorganisms in the soil making the soil less fertile.
- The usual way of increasing production in a land is through multiple cropping, which is possible due to irrigation.
- Multiple cropping means growing more than one crop on a piece of land during the year.
- Planting a tree belt.
- Practising crop rotation.
- Carrying out a large scale irrigation system.
- Using organic fertilisers.
This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, improved efficiency of water power, the increasing use of steam power, the development of machine tools and the rise of the factory system.
- Positive: There are more people because there is enough food. More ideas can be created and the population can become more diverse. - Negative: More competition for space and resources.
How was agriculture affected by the Industrial Revolution?
The increase in food sparked an increase in the population and gave way to a lager labor force, which increased overall productivity in agriculture.
The Agricultural Revolution helped bring about the Industrial Revolution through innovations and inventions that altered how the farming process worked. These new processes in turn created a decline in both the intensity of the work and the number of agricultural laborers needed.
- There were three agricultural revolutions that changed history. ...
- There are two primary methods of farming in the world. ...
- Von Thunen's model of agricultural land use focuses on transportation.
The Agricultural Revolution of the 18th century paved the way for the Industrial Revolution in Britain. New farming techniques and improved livestock breeding led to amplified food production. This allowed a spike in population and increased health. The new farming techniques also led to an enclosure movement.
The Neolithic Revolution started around 10,000 B.C. in the Fertile Crescent, a boomerang-shaped region of the Middle East where humans first took up farming. Shortly after, Stone Age humans in other parts of the world also began to practice agriculture.
What was a direct effect of increased food production during Europe's Agricultural Revolution? The population increased.
How did an agricultural revolution contribute to the population growth? A huge increase in agricultural productivity and output during the agricultural revolution contributed to the population growth. The agriculture revolution created a surplus of food, so fewer people died from starvation.
How do you think population growth contributed to the Industrial Revolution? As population increases, the railroad industry was developed for the shipping of the massively produced goods. As demand rose, more people began to like the products that these industries regulated. Therefore, industry kept expanding.
While both approaches are perceived as being environmentally friendly, they achieve it through very different means. Certain elements of organic farming and sustainable farming overlap, for instance the efforts to reduce/eliminate the use of fertilizers, herbicides, and pesticides, and the planting of cover crops.
Which of the following was a result of the agricultural revolution? Many small farmers became tenant farmers or moved to cities, enclosures became landmarks of wealthy landowners, landowners experimented with new agricultural methods.
How does industry help agriculture?
Agriculture and industries are interdependent i.e. they depend on each other. In other words, they both help each other and without one, the other cannot develop. Agriculture helps various industries by providing them raw materials, labour, a market for their goods and also food for workers in the industrial sector.
1) how and why did the agricultural revolution affect human population size? shift away from hunter-gatherer lifestyle. As people began to grow crops, domesticate animals, and live sedentary lives on farms and in villages, they produced more food to meet their nutritional needs and began have more children.
How did improved farming lead to the development of government? Government developed to help manage the surplus of food, which occurred because of improved farming.
