Summary

Cassava (Manihot esculenta) is a vital food security crop in tropical regions, crucial for smallholder farmers facing production constraints. Its reliability makes it a key carbohydrate source and locally produced food in many low-income countries.

Area of Science:

  • Agricultural Science
  • Food Security Studies
  • Tropical Agronomy

Background:

  • Cassava (Manihot esculenta) is a critical food security crop for smallholder farmers in tropical regions.
  • It is a primary locally produced food and the fourth most important carbohydrate source in the tropics.
  • Production is constrained by climate, soil, and societal stresses in many areas.

Purpose of the Study:

  • To highlight the global significance of cassava production and consumption.
  • To provide an overview of cassava's role in food security and agricultural economies.
  • To present key statistics on world production, yield, and usage.

Main Methods:

  • Data compilation from global production statistics (1994-1996).
  • Analysis of land use, yield, and consumption patterns.

  • Regional production breakdown by continent.

    • Main Results:

    • World production averaged 166 million tons/year on 16.6 million hectares, with a yield of 9.9 tons/ha.
    • 57% of cassava is for human consumption, 32% for animal feed/industrial use, and 11% is waste.
    • Africa leads production (51.3%), followed by Asia (29.4%) and Latin America (19.3%).

    Conclusions:

    • Cassava's reliability and productivity underscore its importance in global food systems, particularly in low-income countries.
    • Significant portions are dedicated to human consumption and animal feed, indicating diverse economic roles.
    • Regional disparities in production highlight the need for targeted agricultural support and research.
