  • Second Green Revolution-1
    SECOND GREEN REVOLUTION for SUSTAINABLE LIVELIHOOD OF SMALL FARMERS Concept Paper BAIF DEVELOPMENT RESEARCH FOUNDATION Dr. Manibhai Desai Nagar, Warje, Pune 411 058, India Phone: 020-25231661 Fax: 020-25231662 E-mail: [email protected] Website: www.baif.org.in Development for Sustainable Rural Livelihood The advancement in space and nuclear technologies will soon take India to the group of developed nations. India has already established its leadership in information technology and heavy engineering. The challenge now is to sustain the growth and ensure economic prosperity, particularly in rural areas. Rural development in India requires priority because more than 65% of the population are still living in villages and over 85% of the rural people are dependent on agriculture for their livelihood. More than 75% being small and marginal holders, most of their earnings are utilised to ensure food security. With the growing population and over-exploitation of natural resources, the pressure on food security and employment generation will continue to mount, further affecting the quality of rural life. Hence, it is necessary to develop a suitable strategy to improve the economy of the rural sector through agricultural development and sustainable use of natural resources. To achieve rural prosperity, the development strategy should focus on improved agricultural production while generating gainful self-employment for small farmers and weaker sections of the society. With year-round employment, the poor can earn enough to meet their basic needs. Agriculture is the main source of rural employment, but being deprived of irrigation facilities, a majority of the small and marginal farmers are heavily under-employed for 6-8 months in a year.

  • Challenges Facing a Second Green Revolution—Expanding the Reach of Organic Agriculture Presentation at USDA Workshop on Organic Agriculture
    Challenges Facing a Second Green Revolution—Expanding the Reach of Organic Agriculture Presentation at USDA Workshop on Organic Agriculture October 6-7, 2005 Washington, D.C. Thomas L. Dobbs South Dakota State University The first Green Revolution • The word “revolution” has been greatly abused, but no other term adequately describes the effects of the new seeds on the poor countries where they are being used. The technological breakthrough achieved by agricultural scientists foreshadows widespread changes in the economic, social, and political orders of the poor countries. [Lester Brown (1970, p. 6), describing the “Green Revolution” in developing countries, in his book Seeds of Change: The Green Revolution and Development in the 1970’s] A second Green Revolution based on organic systems? • The future for organic farming is uncertain. Much depends on the availability and price of fertilizer (especially nitrogen) and farm labor, produce-price relationships, the domestic and world demand for food, concern for soil and water conservation, concern for health and the environment, and U.S. policies toward the development and promotion of organic farming practices. Due to one or more of the above factors, it may be economical for some farmers to produce certain crops and livestock organically rather than conventionally. [From the USDA’s classic Report and Recommendations on Organic Farming (USDA Study Team on Organic Farming, 1980, p. 46)] ‘Influences’ emphasized by analysts of both the ‘first’ and ‘second’ Green Revolutions • Technology, prices, and markets • The structure of agriculture • Public policies Technology, prices, and markets • US organic consumption expanding 20% annually. • Organic food sales 2% of US food sales by 2003.

  • A Second Green Revolution | the Economist
    5/10/2014 How better rice could save lives: A second green revolution | The Economist How better rice could save lives A second green revolution Technological breakthroughs in rice will boost harvests and cut poverty. They deserve support May 10th 2014 | From the print edition WHEN, in 1961, the government of India asked a celebrated wheat breeder, Norman Borlaug, for advice about new seeds, the subcontinent was thought to be on the verge of starvation. China actually was suffering from famine. Borlaug persuaded India to plant a new semi- dwarf variety of wheat in Punjab. The next year, the country also tried out a dwarf variety of rice called IR8. These short-stemmed crops solved a basic problem: old-fashioned crops were long and leggy, so when fed with fertiliser they grew too tall and fell over. Borlaug’s varieties put out more, heavier seeds instead. They caught on like smartphones. Over the next 40 years the green revolution spread round the world, helping ensure that, where its seeds were planted, famines became things of the past. Now a second green revolution is stirring in the fields of Asia. It will not be the same as the first one, since it will depend not on a few miracle varieties but on tailoring existing seeds to different environments. But it promises to bring similar benefits—this time to the poor lands and poorer farmers that the first version passed by (see article (http://www.economist.com/news/briefing/21601815-another-green-revolution-stirring-worlds- paddy-fields-bigger-rice-bowl) ).

  • Education in East Africa: Reviving the Green Revolution
    Anna Johnson, Student Participant Iowa City High School Iowa City, IA Education in East Africa: Reviving the Green Revolution In order to understand how to replicate the Green Revolution, it is important to first examine the original Revolution. In the mid-1960s, Norman Borlaug and a team of scientists began developing a breed of dwarf wheat that would be resistant to many kinds of plant pests and diseases. The wheat was also two to three times more productive than normal varieties of wheat at the time. Borlaug introduced this species into India and Pakistan, which were on the verge of famine. In only one decade, wheat production had quadrupled. Today wheat production is tenfold what it was when Borlaug began his work. By 1974 India was self-sufficient in the production of cereals. Pakistan transformed its wheat production; from 3.4 million tons of wheat per year when Borlaug started to 18 million tons today. Borlaug went on to develop a high-yield rice. This rice was introduced throughout Asia and gave birth to the Green Revolution. The success of the Green Revolution is due in large part to Borlaug’s approach to introducing new crops. The first step is to develop the technology. The second step is to deploy the technology and the third step is to encourage farmers, businesses and government organizations to use the technology on a large scale. Each step should include working with and educating local farmers. In order for the introduction of new crops to be successful, it is imperative that local farmers be involved in the decisions and planning of every step.

This Article analyzes the tools available to achieve this demanding goal. We assess changes in agriculture related to both the organic industry and the high-tech sector that are enabling farmers to be- come more efficient. Critically, biotechnology offers great promise to hasten the pace of increased agricultural efficiency through genetic engineering. While genetic modification has been controversial, we cannot exclude any viable policy option, especially one with so much promise.

  • In His 1968 Bestseller the Population Bomb
    Will Rooney, Student Participant A & M Consolidated High School College Station, Texas Fighting Hunger Using Previously Learned Lessons in East Africa and Ethiopia In his 1968 bestseller The Population Bomb, biologist Paul Ehrlich wrote that “The battle to feed all of humanity is over” and he predicted massive famines in most of the less developed world (Bailey 1). He claimed that “billions would perish” and that these global famines could not be stopped by any means (Bailey 1). The situation in most of the countries which he was talking about was severe and over fifty percent of the world’s population experienced some sort of food insecurity each year at that time (Bailey 1). In addition to Ehrlich, many other scientists also believed that the world could not continue to support increasing population. Luckily, he was proved wrong by a massive effort on the part of Norman Borlaug and the countless thousands of scientists and agronomists across the world who participated in the aptly named “Green Revolution”. Started in the 1940s, it grew to encompass most of Asia, India, the Middle East and many parts of Latin America, making many of these countries self sufficient in cereal grain production (Hesser 68). Most countries, most notably India and China, did not endure the massive famines which were predicted; and many of these same countries are now food secure. The effect of the green revolution was significant; it doubled or tripled yields of most or all crops and it is credited with saving over a billion people thorough its effects (Bailey 1).

  • Lessons from the Green Revolution
    Lessons from the Green Revolution Peter Rosset March/April 2000 Do We Need New Technology to End Hunger? Faced with an estimated 786 million hungry people in the world, cheerleaders for our social order have an easy solution: we will grow more food through the magic of chemicals and genetic engineering. For those who remember the original "Green Revolution" promise to end hunger through miracle seeds, this call for "Green Revolution II" should ring hollow. Yet Monsanto, Novartis, AgrEvo, DuPont, and other chemical companies who are reinventing themselves as biotechnology companies, together with the World Bank and other international agencies, would have the world's anti-hunger energies aimed down the path of more agrochemicals and genetically modified crops. This second Green Revolution, they tell us, will save the world from hunger and starvation if we just allow these various companies, spurred by the free market, to do their magic. The Green Revolution myth goes like this: the miracle seeds of the Green Revolution increase grain yields and therefore are a key to ending world hunger. Higher yields mean more income for poor farmers, helping them to climb out of poverty, and more food means less hunger. Dealing with the root causes of poverty that contribute to hunger takes a very long time and people are starving now. So we must do what we can-increase production. The Green Revolution buys the time Third World countries desperately need to deal with the underlying social causes of poverty and to cut birth rates. In any case, outsiders-like the scientists and policy advisers behind the Green Revolution-can't tell a poor country to reform its economic and political system, but they can contribute invaluable expertise in food production.

[email protected] Received: 28 Oct 2013 Accepted: 05 Nov 2013 Published: 30 Dec 2013 Abstract The second Green Revolution is understood as the development of transgenic varieties, using tools such as genetic engineering and molecular biology applied to the DNA molecule. The product of the second Green Revolution corresponds to genetically modified organisms (GMOs) developed from inter-species cross manipulation and genetic information of some species of interest. The second Green Revolution was established as a strategy to help ensure food security, an increasingly growing population, and demanding of resources, to optimize crop productivity improving or introducing specific characteristics such as resistance to insects and herbicide tolerance to allow GMOs to be more tolerant of natural aggression. The debate on this revolution is maintained, sharpening and raising many interests due to its transversal aspects and impact on social, scientific, economic, political, and ecological issues. This paper aims to review the history, development, and applications of the second Green Revolution framed within the advantages and disadvantages of the environmental components that interact on the soil.
