PROBLEMS FACING IRRIGATION FARMING IN CHINA

PROBLEMS FACING IRRIGATION FARMING IN CHINA
  • Siltation of the canals by deposited alluvium which limits flow of water to the crop fields.




  • Very hot temperatures which lead to high evaporation rates that drain the soils making them unsuitable for crop growth.
  • Salination of the soils near the irrigated zones through capillarity making them less fertile and unproductive.
  • Over use of fertilizers to ensure all-year –round production which end up polluting the soils through affecting the oil PH.
  • Occasional flooding of the river banks during the heavy rainy seasons leading to destruction of some crop fields.
  • High costs of production involved in dredging of silted canals, maintaining and repairing of cracked canals making irrigation farming very expensive.
  • Outbreak of pests and diseases which affect the quality and quantity of crops.
  • Limited land for agricultural expansion due to the ever increasing population which requires more land for settlement and infrastructural development.
  • Pollution of irrigation water by industrial wastes and fertilizers leading to the wilting of crops.
  • Over flooding which washes away the weak canal culverts hence distorting water transfer the crop yields.




SOLUTIONS TO PROBLEMS FACING IRRIGATION FARMING IN CHINA

  • Dredging is carried out to reduce siltation.
  • Use of particles and insect icicles to control pests and diseases.
  • Treatment of industrial wastes before emission to reduce pollution.
  • Hiring migrant workers during the busy periods to avoid labor shortage.
  • Acquiring loans from the government construct and maintain. Irrigation canals.
  • Land redamation of swamps and wastelands to create more land for irrigation farming
