Which agricultural system requires the lowest input of labor and energy?

1) industrial agriculture
2) intensive farming
3) the development and use of genetically modified crops
4) nomadic pastoralism

1 answer

  1. Industrial agriculture typically requires the lowest input of labor and energy compared to the other systems listed. This is because industrial agriculture relies heavily on mechanization, large-scale operations, and the use of inputs such as fertilizers and pesticides, which allows for higher efficiency and productivity with comparatively less manual labor.

In contrast:

  • Intensive farming often requires significant labor and energy inputs to maximize output per unit of land.
  • Genetically modified crops can potentially reduce the need for labor and inputs over time, but the development and implementation phases require considerable effort and resources.
  • Nomadic pastoralism involves a relatively high degree of labor and energy in terms of movement and management of livestock.

Therefore, the correct answer is industrial agriculture.
