...coordinated wheat and rice breeding schemes. They key break-through was the development of short, fertilizer-responsive rice and wheat varieties. These varieties were resistant to disease and insects and were used as model plant types for breeders to adapt to local conditions. The first users of the wheat and rice varieties were in India, Malaysia and Pakistan in 1965 (Evenson, 2003). They produced spectacular increases in yield and their success was characterized as the "Green Revolution". Effects of the Green Revolution The Green Revolution helped to reduce widespread poverty, averting hunger for millions of people. However the Green Revolution also spurred its share of negative consequences, often not because of the technology itself but rather, because of the policies that were used to promote rapid intensification of agricultural systems and increase food supplies. According to Pingali (2012) Africa was the main exception to the success of the Green Revolution in the developing world. During the Green Revolution, the demand for intensification in Africa was quite low because land was relatively abundant. Farmers had little incentive to intensify land use because there was no incentive to save on land costs. In the 1960s and 1970s, national and international programs sought to short cut the varietal improvement process in sub-Saharan Africa by introducing unsuitable crop varieties from Asia and Latin America. This pattern remained until the 1980s, when more suitable varieties...

...The first Green Revolution has yet to reach large parts of the country - especially dryland areas, where poverty incidence and farming risk tend to be highest The Second Green Revolution is a change in agricultural production widely thought necessary to feed and sustain the growing population on Earth. These calls have precipitated in part, as a response to rising food commodity prices, and fears of peak oil among other factors India’s 2010-11 harvest was its largest ever, more than 240 million tons. The next harvest is expected to be even bigger. The government recently announced its target for year 2020: 400 million tons. Is this realistic? What changes would it require, in technology, policies and approach? And could these ideas be applied in other developing countries? To answer these questions, we first look at the Green Revolution of the 1960s and ‘70s, which transformed a chronically food-deficient country into the world’s second largest agricultural producer. Between the mid ‘60s and the mid ‘90s, food production more than doubled, while the intensity of hunger and poverty was cut by half. The Green Revolution was driven by greater use of inputs – irrigation, fertilizer, and high-yielding photoperiod-insensitive ‘dwarf’ varieties of wheat and rice. But what set it apart from similar but less successful efforts in other countries was the integrated approach, combining research, education, policy, institutions and services, backed by strong political will. THE...

...The Sated Hunger Throughout the history of mankind, starvation has been one of the most exigent problems that humans have encountered. Exponential growth of population along with financial crisis generated a chronic food shortage all around the globe. Despite these adversities, Norman Borlaug, the father of the Green Revolution, saved billions of lives by introducing an exceptionally vital genetically modified organism (GMO). Not only had this eminent GMO diminished suffering from privation, its influences have been shown through social and political advancements. Hence, Norman E. Borlaug, who fully utilized his understanding of genetics which unlocked the secret of how life works, is the most influential scientist in the course of history. In the middle of the 20th century, the whole world was undergoing catastrophic circumstances due to World War II and inflation. Eventually, these calamities led to acute famine. Numerous countries attempted to ameliorate their situations by husbandry; however, the lands were not arable on account of poor soil quality, inefficient strategies, and ineffectual grains. Although the situation seemed incorrigible, Norman Borlaug firmly believed that there was a way to engender a high yielding grain: invent a genetically modified grain by uncovering a secret of genome. In the 1940s, he started conducting research in Mexico with thousands of different crops to breed the highest yielding crop. Through Backcrossing, a crossing of hybrid which was used...

...SOUMI BANERJEE UG:2 ; 4th Semester; ROLL NO. : 107 PAPER :Major 5----- INDIAN POLITICS SINCE INDEPENDENCE. THE CHANGING DYNAMICS OF PEASANT MOVEMENT IN INDIA The agrarian structure and land reforms in india have undergone a significant change since Independence both as a result of land reforms during the mid-fifties and more so as a consequence of rapid-technological changes, especially since the mid-sixties. During the late nineteenth and early twentieth century, increase inproduction of commercial crops and introduction of canal irrigation in some parts of india acted as a catalyst in enhancing agrarian development. However, irrigation investment was confined to only limited areas and also the archaic land relations provided a strong barrier to the full exploitation of the benefits of new technology. The land relations were more or less semi-feudal in the Permanently settled ares.Even in the Mahalwari and Ryotwariares, where land transfers had been legalized,large tracts of land had passed to absentee money-lenders and sahukars, due to large-scale peasants’ indebtedness. This resulted in peasant uprising in various parts of India. Moreover because of the non-differentiation in the peasantry and the all-embracing nature of the anti-imperialist struggle, the peasant movement was able to unite all section of the peasantry. The nature of the peasant movement in the colonial period can only be understood in the context of the then existing mode and relations...

...ENVS 1127 Chapters 6, 8, 9 & 10 Homework Assignment 4 Due Noon Tuesday, October 15, 2013 1. Name and describe the four different revolutions leading to significant increases in the human population. What is the importance of the fifth revolution, the environmental revolution, to the size of the human population on this planet? (Chapter 8) The Neolithic Revolution was the first revolutions that lead to a increase in human populations. The Neolithic Revolution occurred approximately 12,000 years ago and was the rise of stable food, the rise of settlements, specialization of labor, and the reduction of mortality. Following this is the Industrial Revolution saw the birth and rise of modern technology and science. Because of new energy sources, production became more efficient and faster. Food could be produced quicker; this also began increased environmental resource exploitation. The Medical Revolution included the increase of epidemics and other rise in diseases that gave children a high mortality rate. This resulted in a low population growth. Because of this, more health regulations were put into place. This in turn, increased human population growth rate. The Green Revolution began with the concern of over-production of food, this lead to an increase in agricultural efficiency. The newest revolution, the Environmental Revolution, consists of policy and industrial changes. This also includes efficient technologies, urban, regional planning and also changes in personal...

The abstract is typically a short summary of the contents of the document.] | Food insecurity has been a long lasting issue in Pakistan – a country where about half its populations suffers from malnutrition to some extent. There is a wide range of causes for this problem, and there are also many solutions – some more effective than others. In this response to the article “Food Insecurity in Pakistan: Causes and Policy Response,” I will attempt to summarize these causes and policy responses, as well as give some of my personal input. There are many causes of food insecurity in Pakistan, the main one, in my opinion, is the ever growing gap between the demand for food and the actual food supply. Although the Pakistan’s food supply has been steadily increasing over the past decades, the population seems to be increasing at a much faster rate. In other words, the increase in the demand has been outweighing the increase in supply, leaving more and more citizens with inadequate food supplies and improper nutrition. This passage from the article shows just how rapidly Pakistan’s population has grown over the past sixty years, “Pakistan’s population...

The National Development Council (NDC) in its 53rd meeting held on 29th May, 2007 adopted a resolution to launch a Food Security Mission comprising rice, wheat and pulses to increase the production of rice by 10 million tons, wheat by 8 million tons and pulses by 2 million tons by the end of the Eleventh Plan (2011-12). Accordingly, a Centrally Sponsored Scheme, 'National Food Security Mission' (NFSM), was launched in October 2007. The Mission is being continued during 12th Five Year Plan with new targets of additional production of food grains of 25...

...PERSPECTIVES ON POPULATION GROWTH Based on the current trend, there will be a total to about 9.2 billion people on the earth by mid-century, fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute, 2014). This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that drive our lives can be sustained indefinitely can support humanity in the long term. We operate on the assumption that, on a finite planet, nothing physical can grow indefinitely. As our population grows, the fewer resources there are for each of us and members of other species with which we share the planet. Because of the finite nature of the resources and the ability of our planet to provide us infinite resources, we need to, carefully consider some aspects of our existence, like our consumption, acceptable living standards, what technologies make best use of the resources available and explore ways to preserve the ecosystems on which we depend. The primary concern regarding rapid global population growth includes aggravated poverty, starvation, water scarcity, political & social instability and depletion of natural resources. How will we feed 9.2 billion people when high food prices and the global economic recession have pushed 100 million more people than last year into...

...Anthony Mitchell Hessler 5/8/12 The Social-Economic, Political, and Environmental Impacts of Unregulated Population Growth Ladies and gentlemen of the Senate Select Committee on Intelligence, mankind is well on its way to answering a seldom asked yet vitally important question pertaining to its sustainability. "How many people can inhabit this planet sustainably?" This is a question that should have been looked into decades ago, yet the answer is still unclear. With no regards to what the answer may be mankind persists in rapidly escalating its population as if the worlds sustainable population capacity is limitless. With the numerous problems that currently plague mankind, overpopulation is perhaps the most threatening and overlooked issue. If current population trends continue there will undoubtedly be terrible repercussion to face in the future. Problems arising from overpopulation will eventually have a grim impact on the socio-economic systems and political systems of the world along with the environment as a whole, the worst of which could lead to the annihilation of the human race. This is why population growth should be a global concern that should be recognized, examined, and dealt with immediately. To understand the impacts of overpopulation one must first understand the concept of overpopulation. Overpopulation is a state wherein the population density of an area has grown large enough to exceed what would be the natural sustainable inhabitant capacity...

...Many things threaten our world: war, climate change, and poverty are among them. While many people are concerned with our economy, our oil dependency, and dwindling food and water supplies, others acknowledge the simple reason as to why we are faced with these issues – the Earth is overpopulated. Exponential growth has been seen in our world population over the past two centuries, with a grand total of 7 billion (6.97 as of my last essay) people roaming the Earth today (Tomkin, 2011). Mankind has ventured a long way to reach the position we are in currently, and in this essay I will explain how we got here and where we might be headed, citing examples of previous efforts to combat overpopulation. I then will suggest my own solution to the problem, and then give detailed analysis as to why my method should be implemented. Over the course of mankind’s time on this planet, the population has changed rather drastically. Since long before the birth of Christ, thousands of years ago, the Earth had held a stable number of approximately one million people (Zhang, et al, 2011). The stability was vastly due to the scavenger lifestyle of early humans, a world where only the strong survived. Throughout the Middle Ages population increased to an estimated 250-500 million people, yet took hard hits due to disease and plague (Rosling, 2010). The flux in population was due to the invention of agriculture, which at this time was the sole reason that Earth’s carrying capacity had increased...

...Effects of over population in Mexico City There are parts of the world that have an alarming overpopulation rate, one of these locations is Mexico city which is located in the Federal District, Capital of the Country of Mexico. Mexico City's enormous population continues to rapidly increase every day. With approximately 20 million residents; up from 9 million only 20 years ago, Mexico City is considered the most populous urban center on earth. There are many people in the country of Mexico who move to Mexico city because they feel that there are better life and employment opportunities there, however there are also hundreds of people that are born there every year and these factors contribute even more to its overcrowding and overpopulation. Mexico City has a poor living habitat because it is located in the Valley of Mexico, and is highly vulnerable to volcanic eruptions and earthquakes. These natural disasters have caused much destruction making these grounds to be weak and dry, never the less the city is rapidly diminishing water supply which adds a danger problem to the overcrowding of its population. Once its water supply is gone, the only way to receive water will be to transport it from across the mountains. Not only does the city have to pipe water in, but it also has to pipe the sewage out of waste-filled areas. This would be a very expensive undertaking and could cost Mexico City a large amount of money. In...

...The Threats to Global Food Supplies Weiwen Huang Student Number: 2171584 Class: Syllabus 4/1 Tutor: Siriol Lewis In the past half-century, food production had a significant growth. At the same time, the global demand for food rose rapidly. It is required more food supply to feed the global growing population. Thus the global population growth is the main factor of rising food need. It was predicted that the global population will reach over 9 billion people by 2050(Black, 2010 cited in Slaght, 2012, p.28). Another factor is that food consumption per person shows a rising trend with increased consumption of animal protein (Leaver, 2011). Therefore, the primary task of global food supplies is that making sure the global food production can match the global food demand. It is not easy to be done, because there are many menaces to global food provision. This essay will discuss some threats for food supplies and identify several solutions to make the assignment easier to be fulfilled. First of all, different resources constrict food production, such as land. It is well known that if food output want to be increase, it is necessary to increase the area of farmland. However, over the past 50 years the global farmland acreage just grew slightly, which did not match the growth of population. The agricultural land area for each person had fallen from 1.3 hectares to 0.72 hectares during 1967-2007. (Leaver, 2011) This means that average amount of food that can be consumed per person...
