Q: For an irrigation project, culturable command area (CCA) =
  • A. Culturable command area (CCA) = Gross command area (GCA)
  • B. Culturable command area (CCA) = Unculturable area = Gross command area (GCA)
  • C. Culturable command area (CCA) = Gross command area (GCA) – Unculturable area
  • D. Culturable command area (CGA) = Gross command area (GCA) + Unculturable area
Correct Answer: Option C - Culturable Command Area (CCA)–The portion of the GCA which is culturable or cultivable. CCA = GCA – Uncultivable area Gross Command Area (GCA)–Total area which can be irrigated by canal system if unlimited quantity of water is available is known as gross command area.
