Agricultural System Case Study: Intensive Rice Farming Ganges Flashcards
Inputs
5 month growing season Temperatures over 21 degrees Monsoon rainfall over 2000m (uses 90% of Asia's agricultural water) Flat, flooded land Large labour force Rice seeds
Processes
Ploughing
Planting rice
Harvesting wheat
Weeding
Outputs
Rice
Manure for buffalos for fertilising
Rice seeds
Vegetables
Problems
Flooding can sometimes be so severe that they destroy the crop
Drought can fail crop
Little use of machinery/modern methods
Farms are too small leading to food shortages
Majority of farmland held by a few wealthy landowners
Changes
Green revolution has increased yields 3 times
Irrigation-wells, indundation canals, terraces
Appropriate technology-wells, local labour, renewables resources
Soil conservation
General information
Ganges Basin is India’s most extensive and productive agricultural area
Lower Ganges Valley is an important area of intensive subsistence rice cultivation
Why is the Ganges Basin perfect?
Temperatures of over 21 degrees
2000mm annual rainfall
Large amount of flat land that can be flooded to create padi fields
Flooding deposits fertile alluvium which allows rice to be grown well
Continuous growing season allows 2 crops to be grown on the same piece of land a year-rice when monsoon rain falls and vegetables in dry season
