Questions and Answers

What is a key advantage of raised bed farming in temperate regions with cold winters?

  • Raised beds prevent soil erosion in urban areas
  • The beds warm up quicker than the barren ground in the spring, extending the growing season (correct)
  • Raised beds require less maintenance compared to traditional farming methods
  • Raised beds provide better protection against pests and diseases

    • How are amphibious farming areas secured in place?

  • By building a solid foundation on the lakebed using bricks and mortar
  • By using concrete pillars to anchor the farming islands
  • By driving wooden stakes into the lakebed and establishing a perimeter with woven reed fences (correct)
  • By creating a floating platform using buoyant materials

    • What is the primary purpose of floating agriculture?

  • To create additional recreational spaces on water bodies
  • To utilize inundated areas for food production (correct)
  • To provide a habitat for aquatic organisms
  • To prevent flooding in low-lying areas
