Agricultural_Development

Before the start of the twentieth century, the overwhelming majority of increases in inelegant production were the result of an increase in the summate of cultivated areas. However, the start of the 21st century has come to demand that nearly all increases in farming(a) production result from the increased productivity of real cultivated areas, thereby leaving an extremely window of time for countries to make the dramatic shift from a system of production that has long been based on resources to one that is based on science (Ruttan, 2001 p. 179).To quantify the shift in terms of population, as the global population neared $1 billion, the increased demand for agriculture was met by expanding farm land area. In sharp contrast, the population, and consequently the demand for agriculture, more than manifold after 1950. Virtually all of the demand, which suddenly doubled, was met by increase farm productivity (Federico, 2005 p. 388).For developed countries, the shift from a most res ource-based system to a science-based system began in the 19th century. But, unfortunately for maturation countries, these changes did not catch to take place until the second half of the 20th century, thereby leaving the developing countries at a disadvantage because the demands place on agriculture had doubled by this time.Population and income growth were the underlying causes of this two-fold increase. Because demands are expected to rapidly double again, substantial and scientific and technical effort will be required in the worlds poorest in countries in order for them to complete the transition to the science-based system (Ruttan, 2001 p. 179).Since the 1950s, the overall understanding of agricultures role in economic development has increased. In the past, development economists in premodern and traditional societies viewed agriculture as atmospherics as sustained annual growth rates as low as 0.5 to 1% were feasible over extended periods.With industrialization, agricul tural output growth rates increased to 1.5% to 2.5%, rates which were sustained for extended periods of time in Western Europe, North America, and Japan. Since 1950, growth rates have shifted further upward to 3%.This increase primarily took place in newly developing countries ilk Brazil, The Peoples Republic of China, and Mexico. As output growth rates steadily increased, economists came to adopt the new view that agriculture was dynamic rather than static (Ruttan, 2001 p. 180).By 1960, the high-payoff input model merged as a new theory by which economists were attempting to understand agriculture. It took into consideration agroenvironmental constraints and is based on the conclusion that these constrains make agricultural technology location specific.For example, it was discovered that technologies that were developed in highly developed countries were generally not transferable to less developed countries which had different climates and resource endowments.Additionally, it app eared obvious that because poor countries were not providing peasant farmers with technical and economic opportunities, reallocating resources in traditional peasant agriculture would only produce marginal productivity gains.Under the high-payoff input model, it was argued that developing economies could be transformed by investments from the public and private sectors to make high-payoff technical inputs available to poor farmers (Ruttan, 2001 p. 187).Between the 1970s and mid 1980s, Hayami, Ruttan ,and Binswanger developed a new agricultural model in which conditions in the economic system arose from technical and institutional change. This model was based on the recognition that there is more than one line to technological development.These different paths to development make it possible for a country to substitute more abundant factors for scarce factors. Techniques which allow for the substitution of other job factors are termed labor deliverance, while techniques which fac ilitate the substitution of other land factors are referred to as land salvage.Mechanical technology corresponds with labor saving technology, as it substitutes power and machinery for labor. Biological technology, which tends to substitute intensive production practices and industrial inputs for land, corresponds with land saving techniques.Chemical fertilizers, increased recycling of manures, pesticides, and pathogen-resistant crops are example of land saving technologies. Mechanical technology and mechanical processes were the driving force of the industrial revolution. But biological and chemical technologies became more prominent in the latter half of the 20th century (Ruttan, 2001 p. 188, 190).
