The Green Revolution was an agricultural strategy introduced by the Indian government in 1966-67 to increase food production. It involved the introduction of high-yielding variety seeds, chemical fertilizers, and farm machinery. As a result of the Green Revolution, agricultural production increased through the use of Mexican wheat seeds, large amounts of fertilizers and pesticides, irrigation canals and borewells, and tractors. However, it also led to problems like the extinction of traditional seed varieties, soil degradation, increased pest attacks, farmer debt, and reduced job opportunities.

Green revolution
The document discusses the history and impact of the Green Revolution. It describes three major agricultural revolutions: 1) the Neolithic Revolution involving the transition to farming, 2) the British Agricultural Revolution involving increases in labor and land productivity, and 3) the Green Revolution involving the development and adoption of high-yielding varieties of wheat and rice in developing countries between the 1950s-1960s. Key organizations involved in the Green Revolution included the Ford Foundation and Rockefeller Foundation. Norman Borlaug was a leading agricultural scientist who developed disease-resistant wheat varieties, increasing yields and saving over a billion people from starvation. The Green Revolution spread to India in the 1960s and significantly increased food grain production through the adoption of new seeds, fertilizers,

The document discusses the Green Revolution in India which began in the 1960s. It was a period of increased agricultural production led by Norman Borlaug's development of high-yielding varieties of wheat. This involved the introduction of modern farming techniques like irrigation, fertilizers, and pesticides. The Green Revolution initially focused on wheat and rice in Punjab and Haryana. It led to increased food grain production but also issues like pollution, disease, and unemployment. The document calls for a second Green Revolution with a focus on non-food grains and improving rural infrastructure and market opportunities.
Green revoulation in agriculture
The presentation discusses the Green Revolution in agriculture, which refers to a large increase in crop production through the use of modern techniques. It was sparked by scientists like Norman Borlaug who developed high-yielding varieties of major crops that responded well to fertilizers and irrigation. This led to a crop surge starting in the 1960s, boosting food production in countries like India, Mexico, and Bangladesh. While the Green Revolution increased yields and food security, it also led to environmental issues from overuse of chemicals and could leave small farmers unemployed. More sustainable farming methods are now needed.
Green Revolution in Developing Countries
The Green Revolution of the 1940s-1960s led by Norman Borlaug developed high-yielding varieties of wheat and rice to increase global food production and reduce hunger. Now, genes providing insect, chemical, and environmental resistance are being inserted into crops via transgenic methods. Bt crops containing a natural insect-killing gene have benefits like reduced pesticide use and increased yields but also concerns about their long-term impacts and corporate control. For Bt crops to best help the poor, issues around access, enabling environments, stability, and consumer protection must be addressed.

Green Revolution
Agriculture before the Green Revolution was limited by lack of irrigation and technology, resulting in low and unpredictable crop yields. This caused global concerns about the ability to feed growing populations. After independence, India established agricultural institutions and saw some improvements but productivity remained low. The Green Revolution starting in the 1960s introduced high-yielding varieties of wheat and rice, irrigation projects, and chemical fertilizers, doubling food production in India and alleviating famine concerns. Agricultural advances after the Green Revolution continued to increase yields and crop diversification.

Agricultural diversification
1) Agricultural diversification involves reallocating farm resources like land, capital and equipment to non-farm activities or alternative crops. It helps reduce risk and respond to changing demands, policies and climate change.
2) There are two approaches to crop diversification - horizontal which adds new high-value crops, and vertical which adds value through processing.
3) Diversification is needed in India due to monsoon reliance, lack of irrigation, and to provide employment outside of agriculture. Government policies aim to promote diversification through insurance, technology missions, subsidies and other support.
Introduction to Farm Power Machineries in Bangladesh
1. The document discusses the sources of farm power in Bangladesh including human power, animal power, mechanical power, electrical power, and renewable energy. It also discusses the merits and demerits of different power sources.
2. Farm mechanization aims to apply engineering principles to agricultural operations to increase crop yields. The scope of farm mechanization has expanded with improved irrigation, high yielding varieties, and increased fertilizer and pesticide use.
3. Benefits of farm mechanization include timely operations, precision, improved work environment, increased productivity, economic returns, and rural progress. However, problems include fragmented lands, farmers' limited buying capacity, lack of quality machines, and technical knowledge.
Impact of Green Revolution on Indian Agriculture
The document discusses the Green Revolution in India that occurred in the late 1960s. It introduced high-yielding varieties of seeds, increased usage of fertilizers and irrigation, which led to a significant increase in food grain production. However, the Green Revolution also had negative environmental and social impacts. There is now a need for a second Green Revolution that focuses on sustainable agricultural practices to continue feeding India's growing population.
The Green Revolution In India
The Green Revolution in India aimed to address food shortages through high-yielding crop varieties that required intensive chemical use. This transition from traditional to industrial agriculture had significant social, political, and environmental consequences. It increased tensions by prioritizing large farms, exacerbating inequalities. Over-application of chemicals degraded soils while dependence on external inputs rose. Ultimately, declining returns sparked unrest among small farmers and added to regional ethnic/religious conflicts, such as the crisis in Punjab between Sikh farmers and the central government.
Green revolution
The Green Revolution in India refers to the period in the 1960s-70s when agricultural productivity increased dramatically due to the adoption of new technologies and high-yielding varieties of seeds, brought about through initiatives like those of M.S. Swaminathan. This helped increase food grain production, especially in states like Punjab, Haryana, and Uttar Pradesh. However, long term problems arose due to overuse of chemicals, loss of biodiversity, rising costs for farmers, and increased regional disparities between areas that could benefit and those that could not.
Green Revolution
The Green Revolution in India occurred between 1967-1978 and focused on increasing food grain production through the introduction of high-yielding variety seeds, expansion of irrigation through dams, and double-cropping existing farmland. This led to a significant increase in food grain production, with India becoming a net exporter, but the benefits were not evenly distributed across India and questions remained about long-term sustainability and self-sufficiency.
Organic farming presentation
This document provides an introduction to organic farming. It discusses that organic farming prohibits the use of synthetic pesticides, fertilizers, genetic engineering, sewage sludge, and antibiotics or hormones. The history of organic farming is outlined, noting it was the original form of agriculture and the modern organic movement began in the 1920s in Europe. The aims of organic farming are listed as maintaining soil fertility, reducing costs, effective resource use, and providing quality foodstuff while avoiding pollution. Methods like crop diversity, pest control, livestock, and plant nutrition are described. The advantages include reduced costs, increased yields, and health benefits from consuming organic foods.
Green revolution
The document discusses the Green Revolution which occurred between the 1940s and late 1960s and increased agricultural production worldwide. It achieved this through the introduction of high-yield seed varieties, increased fertilizer and pesticide use, expansion of irrigation, and development of new farming techniques. These developments led to greater yields per acre and more than one harvest per year in some areas.
farm mechanization
1) Farm mechanization in India faces problems due to small land holdings, lack of knowledge and financial constraints among small farmers. Government initiatives to promote mechanization include training programs and subsidies.
2) The average farm power availability in India is 1.5 kW/ha but varies widely between states. States with higher availability such as Punjab have much higher agricultural productivity. In Assam, availability is only 0.8 kW/ha, below the national average.
3) Strategies to increase farm mechanization in India include developing equipment suitable for different terrains, establishing farm machinery banks, increasing average power availability, and strengthening collaboration between farmers and researchers.
Privatization of agriculture extension
Privatization of agriculture extension involves transferring ownership of extension services from the public sector to private organizations. This began in India in the 1980s to improve access to inputs and create a more efficient system, as the public system had shortcomings like only reaching a small portion of farmers and having an ineffective top-down approach. Private extension is now provided by groups like agricultural consultants, farmers associations, input companies and NGOs. While privatization reduces the economic burden on the government and increases efficiency, it could hamper free sharing of information if farmers don't disseminate learning to others and only commercial farmers benefit.
Agricultural Technology for Development
The return of high food prices and the need to adapt to climate change have revived interest in agricultural technologies adapted to smallholders, in particular women. Sustainable intensification of smallholder production will require a shift to knowledge-intensive agriculture that combines local knowledge and the latest sustainability science to adapt practices to local ecosystems and increase resilience to climate change, price and other shocks. Poor farmers, often women, usually cultivate in more extreme environments in addition to being less connected to markets. A radical change in the focus of national agricultural plans and substantial investment are needed to unleash smallholder production potential, contributing to achieving MDGs and boosting food production to meet the 70% increase needed by 2050. A holistic approach is needed to raise productivity and resilience of agriculture and supporting ecosystems as well as the efficient and equitable functioning of agricultural supply chains.
Diversification of agriculture production
Diversification in agriculture involves allocating resources like land, capital and labor to new crops or non-farm activities. This helps reduce risk and respond to changing demands and policies. Factors leading to diversification include reducing risk, responding to consumer or policy changes, and adapting to external shocks like climate change. Diversification can involve shifting to higher-value crops or transforming the workforce to activities like livestock, fisheries or non-agriculture. This provides more income opportunities for rural farmers.
Green Revolution
Green Revolution is a face used to describe spectacular increase in the production of food. A large increase in crop production in developing countries achieved by the use of artificial fertilizers, pesticides, and high-yield crop varieties.

Climate smart agriculture 2
Agriculture in developing countries must undergo a significant transformation in order to meet the related challenges of achieving food security and responding to climate change. Projections based on population growth and food consumption patterns indicate that agricultural production will need to increase by at least 70 percent to meet demands by 2050. Most estimates also indicate that climate change is likely to reduce agricultural productivity, production stability and incomes in some areas that already have high levels of food insecurity. Developing climate-smart agriculture is thus crucial to achieving future food security and climate change goals. This seminar describe an approach to deal with the above issue viz. Climate Smart Agriculture (CSA) and also examines some of the key technical, institutional, policy and financial responses required to achieve this transformation. Building on cases from the field, the seminar try to outlines a range of practices, approaches and tools aimed at increase the resilience and productivity of agricultural product systems, while also reducing and removing emissions. A part of the seminar elaborates institutional and policy options available to promote the transition to climate-smart agriculture at the smallholder level. Finally, the paper considers current gaps and makes innovative suggestion regarding the combined use of different sources, financing mechanism and delivery systems.
Natural Farming- Zero Budget Natural Farming
This document provides information about natural farming and zero budget natural farming (ZBNF) in India. It discusses the principles and practices of natural farming according to major proponents like Masanobu Fukuoka, Subhash Palekar who developed ZBNF, and initiatives in Indian states to promote ZBNF. It summarizes the key drivers of ZBNF adoption, impact on yields, costs and incomes, and ongoing research efforts including ICAR's evaluation of ZBNF claims and potential large scale impacts on Indian agriculture.
Green revolution
The document discusses the Green Revolution in India, which involved the introduction of high-yielding crop varieties, artificial fertilizers, and pesticides that significantly increased crop production. It notes that the Green Revolution was led by American biologist Norman Borlaug and describes some of the key aspects, including how fertilizers allowed for extra nutrient supply to crops, leading to higher yields. However, it also mentions that farmer suicides have increased after the Green Revolution. The document concludes by suggesting it is time to move toward an Organic Revolution that is chemical-free, organic, fair trade, and eco-friendly.
Market-Led Extension to Enhance Producer Share
The document discusses the transition from production-led extension to market-led extension in India. It notes that while production-led extension made India self-sufficient in food, farmers did not receive remunerative prices. With globalization, a shift to market-led extension is needed. Farmers now need to transform from mere producers to producers and sellers in wider markets. Case studies show how market-led extension through groups, market intelligence, and linkages have increased farmers' incomes and crop productivity in various states. The role of extension is expanding beyond production to focus on quality, market needs, and marketing.
Rice culture and greenhouse gas emission
This document discusses rice cultivation practices and their impact on greenhouse gas emissions. It begins with an introduction to climate change impacts on agriculture and rice production. It then describes different rice cultivation methods like transplanted rice, direct seeded rice, system of rice intensification, and aerobic rice. The document discusses the main greenhouse gases emitted from rice including carbon dioxide, methane, and nitrous oxide. It provides data on greenhouse gas emissions from Indian agriculture. Finally, it discusses various mitigation strategies for different rice cultivation practices like mid-season drainage, use of slow-release fertilizers, and alternate wetting and drying irrigation.
Subsistence farming
This document discusses subsistence farming, which provides a sustainable source of food for families or communities. There are two main types - family-based small farms where all produce goes to the immediate family, and community-based somewhat larger farms where most produce is used by the community. Subsistence farms are found in impoverished areas where they support families barely getting by, and also in developed nations where money plays a larger role. Key methods used include intercropping to maximize space, composting to improve soil, and chickens to fertilize land. Water is obtained through rain barrels or natural wells. Some farms earn income through CSAs or farmers markets.
Ppt impact on green revolution
The document discusses the impact of the Green Revolution. It began in the 1960s when high-yielding varieties of crops and increased use of fertilizers and irrigation led to dramatic increases in agricultural production. This included the introduction of semi-dwarf, high-yielding varieties of wheat and rice into India that doubled and tripled yields. While food grain production grew substantially, the overuse of chemicals caused issues like soil degradation and pollution over time. The Green Revolution saved many from famine but was not a sustainable solution due to its environmental impacts.
Intensified Agriculture and its Merits and Demerits
Agriculture has intensified significantly over the past century due to population growth and industrialization. This intensification involved adopting mechanization, irrigation, fertilizers, pesticides, and high-yield crop varieties to boost productivity on existing farmland rather than expanding into new areas. While intensification increased food supply, it has also led to environmental issues like soil acidification, pollution from excess nutrients, and loss of biodiversity. Maintaining sustainable agricultural practices that balance productivity with environmental protection remains an ongoing challenge.

7. green revolution
The green revolution significantly increased agricultural production in developing countries between the 1940s-1960s through programs introducing high-yielding crop varieties, irrigation infrastructure, and use of fertilizers. This transformation was initiated by organizations like the Rockefeller Foundation and led to widespread adoption of new crops like rice varieties in countries in Asia and Latin America. While food production increased dramatically, the green revolution also had environmental and social impacts, and its benefits were not evenly distributed. Overall, the green revolution is both praised for preventing famine and criticized for its unintended consequences.
Green Revolution
The green revolution aimed to increase crop yields through new high-yielding varieties of rice and wheat. This led to successes like tripling of yields in India, allowing the country to become self-sufficient in wheat and rice. However, there were also failures, as only wealthy farmers could afford the costs of the new seeds and technologies, which increased rural unemployment and migration to cities. The green revolution benefited some but was not financially viable for most small farmers. Appropriate technology tailored to existing skills could help increase living standards for more people.

Green revolution an over view
The green revolution was a period in the 20th century where agricultural productivity greatly increased due to new technologies. Norman Borlaug conducted research in Mexico in 1940 that developed high-yielding varieties of wheat, laying the foundation for the green revolution. In 1965, under Dr. M.S. Swaminathan, the Indian government accelerated the green revolution through initiatives like expanding farmlands, introducing artificial monsoons, enabling multiple cropping per year, and developing high-yield crop varieties that used fertilizers and pesticides. The green revolution transformed many nations from food deficient to self-sufficient.

However, overuse of chemical pesticides and fertilizers also led to negative environmental impacts like land degradation over time.
Green revolution
Green Revolution began in India in the 1960s in response to concerns about food security. New high-yielding varieties of wheat and rice developed by Dr. Norman Borlaug were introduced, along with increased use of irrigation, fertilizers, pesticides, and farm mechanization. This led to greatly increased food grain production, making India self-sufficient and reducing the need for food imports. Key components of the Green Revolution included development of infrastructure like irrigation projects, rural electrification, and agriculture support services. The document provides details on the introduction and impact of these Green Revolution strategies and technologies in India.
Organic farming presentation rrrrrrrr
Before the Green Revolution, India faced food scarcity and relied on imports due to traditional organic farming practices. In the 1960s, under M.S. Swaminathan's leadership, the Green Revolution introduced high-yielding varieties and chemical fertilizers/pesticides, increasing food production and attaining self-sufficiency. However, continuous chemical use degraded soils and polluted water/air. While chemical farming boosted short-term yields, organic farming maintains soil health and is more sustainable. Organic farming avoids chemicals and uses organic manures/compost to nourish soils and crops. Both methods have benefits and drawbacks, so policy support is needed for organic techniques to increase production in an environmentally friendly way.

powe rpoint presentation Green revolution 2016
The document discusses the strategies and impacts of the Green Revolution in India. It introduces strategies used like high yielding variety seeds, chemical fertilizers, construction of canals and bore wells, and increased use of tractors. The Green Revolution aimed to address high poverty, low agricultural productivity, and lack of infrastructure. Its positive impacts included making India self-sufficient in food, controlling food prices, and increasing buffer stocks by boosting rice and wheat yields. However, it also increased disparities between large and small farmers, made crops more vulnerable, caused unemployment, and led to water pollution from excessive chemical use.
Green revolution
The Green Revolution significantly increased agricultural productivity in India through the introduction of high-yielding varieties of wheat and rice, increased fertilizer and pesticide use, and improved irrigation techniques. Led by Indian agronomist M.S. Swaminathan and supported by Mexican scientist Norman Borlaug, the Green Revolution transformed India from a food-deficient nation in the 1960s to a major food exporter by the late 1970s through high crop yields that established India as one of the world's largest agricultural producers. However, overuse of chemicals polluted water sources and soils over time. Future agricultural plans need better management of irrigation and controls on pesticide and fertilizer use to minimize environmental impacts.
Green Revolution in India.pptx
The Green Revolution was a period in the 20th century when agricultural productivity greatly increased due to new technologies. Chemical fertilizers and pesticides were developed that allowed for higher crop yields by providing extra nutrients to crops and controlling weeds, insects, and diseases. The Green Revolution started in the 1940s and spread around the world in the 1950s and 1960s, helping to avoid widespread famine. It introduced high-yielding varieties of cereal grains, expansion of irrigation infrastructure, modern agricultural technology such as mechanized cultivation, and increased use of fertilizers and pesticides to boost production.
ORGANIC-FARMING.pdf
This document discusses organic farming in India. It defines organic farming as using green manure, compost, crop rotation, and biological pest control instead of chemicals. The objectives of organic farming are to increase genetic diversity, promote natural pesticides, ensure proper soil cultivation, and maintain soil structure and fertility. Sikkim has been declared India's first fully organic state. The government is taking several initiatives to promote organic farming such as missions and schemes. Organic farming provides benefits like improved nutrition, environmental sustainability, and food security.
Green Revolution: Changes in economy and culture.pptx
The presentation discusses how the Green Revolution changed economies and cultures. It introduced high-yielding varieties of wheat and rice that increased agricultural production and improved food security. This led to economic changes like higher incomes for farmers, more rural jobs, and industrial growth to support mechanized farming. However, overuse of chemicals degraded land quality over time. Culturally, traditions and simple living gave way to materialism and westernization as villages grew more connected to modern culture. While the Green Revolution brought many economic benefits, it also accelerated the transformation of rural societies.
