Recent research said that coffee production across the world is threatened by synchronous crop failures, characterised by broad, simultaneous yield losses in various countries at the same time.


About Coffee production

  • The vast majority of the world’s coffee comprises two species — Coffea Arabica (Arabica) and Coffea Canephora (Robusta). Coffee, especially Arabica, is considered a sensitive crop, vulnerable to climate variability and change.
  • Climatic conditions required for coffee production —
      • It requires a hot and humid climate for its growth.
      • Temperatures ranging between 15°C and 28 °C
      • Rainfall — 150 to 250 cm.
      • Soil Well-drained, loamy soil containing a good deal of humus and minerals like iron and calcium are ideal for coffee cultivation.
      • It is generally grown under shady trees.
      • Dry weather is necessary at the time of ripening of the berries.
      • It is grown on hill slopes at elevations from 600 to 1,600 metres above sea level.
  • In India coffee is largely cultivated in Karnataka, Kerala, Tamil Nadu, Andhra Pradesh and Odisha, among which, Karnataka produces the most with over 70% of the total output.
