    During the Green Revolution, agricultural practices from more developed countries diffused to less developed countries in Asia and Africa. Which of the following best explains the Green Revolution's highly variable level of success in increasing agricultural yields?

    A. The increased yield of the Green Revolution in sub-Saharan Africa decreased the incidence of famine, but the program was unsuccessful in India because of poor soil quality.

    B. Small-scale farmers in Asia often lacked the resources necessary to acquire the hybrid seeds and the chemical inputs to grow them, leaving large gaps in the success of the Green Revolution outside of urban cores.

    C. The Green Revolution was not successful in China because the strain of rice produced was prone to widespread crop failures, and China dropped out of the program.

    D. Rice production surpassed all other crop production in sub-Saharan Africa, but corn production in Mexico was less successful because of the negative impact on the environment.

    E. Persistent famine has occurred in India since new technologies associated with the Green Revolution were implemented because only the wealthy could afford the increased cost of the improved strains of rice.

    B. Small-scale farmers in Asia often lacked the resources necessary to acquire the hybrid seeds and the chemical inputs to grow them, leaving large gaps in the success of the Green Revolution outside of urban cores.

    Between 1950 and 1990, wheat production in India in average pounds per acre more than tripled, which allowed India to meet its population's need for food. Which of the following best explains this change?

    A. The elimination of poverty in India's rural regions

    B. The use of genetically modified seeds

    C. The increase in microloan programs that provide farmers with credit

    D. The use of large farm tractors and combine harvesters

    E. The use of improved plant hybrids and agricultural chemicals

    E. The use of improved plant hybrids and agricultural chemicals

    In less developed countries, pesticides are typically applied by hand, whereas pesticides are typically applied by tractors or aircraft in more developed countries. Which of the following best explains the risks associated with pesticide applications?

    A. Crop dusters are at risk when applying pesticides with aircraft in more developed countries, whereas environmental pollution is a risk in less developed countries.

    B. Farm animals used to plow fields are at risk from pesticides in more developed countries, whereas environmental pollution is a risk is less developed countries.

    C. Farmers' health is at risk in less developed countries, whereas environmental pollution is a risk in more developed countries.

    D. Crops are at risk in more developed countries, whereas environmental pollution is a risk in less developed countries.

    E. Contract harvesters are at risk in more developed countries, whereas environmental pollution is a risk in less developed countries.

    Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed.

    Systems[edit]

    Continuous grazing by sheep or cattle is a widespread extensive farming system, with low inputs and outputs.

    Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labour are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional sunlight.

    Geography[edit]

    Extensive farming is found in the mid-latitude sections of most continents, as well as in desert regions where water for cropping is not available. The nature of extensive farming means it requires less rainfall than intensive farming. The farm is usually large in comparison with the numbers working and money spent on it. In 1957, most parts of Western Australia had pastures so poor that only one sheep to the square mile could be supported [1]

    Just as the demand has led to the basic division of cropping and pastoral activities, these areas can also be subdivided depending on the region's rainfall, vegetation type and agricultural activity within the area and the many other parentheses related to this data.

    Advantages[edit]

    Extensive farming has a number of advantages over intensive farming:

    Less labour per unit areas is required to farm large areas, especially since expensive alterations to land (like terracing) are completely absent.

    Mechanisation can be used more effectively over large, flat areas.

    Greater efficiency of labour means generally lower product prices.

    Animal welfare is generally improved because animals are not kept in stifling conditions.

    Lower requirements of inputs such as fertilizers.

    If animals are grazed on pastures native to the locality, there is less likely to be problems with exotic species.

    Local environment and soil are not damaged by overuse of chemicals.

    The use of machinery and scientific methods of farming produce a large quantity of crops.

    Animals bred in larger areas develop more efficiently.

    Disadvantages[edit]

    Extensive farming can have the following problems:[2]

    Yields tend to be much lower than with intensive farming in the short term.

    Large land requirements limit the habitat of wild species (in some cases, even very low stocking rates can be dangerous), as is the case with intensive farming.

    Extensive farming was once thought to produce more methane and nitrous oxide per kg of milk than intensive farming.[3] One study estimated that the carbon "footprint" per billion kg (2.2 billion lb) of milk produced in 2007 was 37 percent that of equivalent milk production in 1944.[4] A more recent study by CIRAD, however, found that extensive livestock systems impact the environment less than intensive systems.[5]
