During drought planning for landscapes, which system type is preferred?

• A. Above-ground sprinkler systems
• B. In the ground or drip systems
• C. Fogging systems
• D. Hand watering with a hose

Answer: (B)

During drought planning, the aim is to water plants efficiently with minimal losses. In-ground drip irrigation delivers water directly to the root zone in a slow, targeted way, which greatly reduces evaporation, runoff, and overspray. This level of precision makes it the most water-efficient choice for landscapes under drought conditions. Above-ground sprinklers spray larger areas and are more prone to wind drift and evaporation, wasting water. Fogging systems aren’t practical for typical landscape irrigation and don’t wet root zones effectively. Hand watering with a hose is labor-intensive and hard to regulate, often leading to uneven watering. So, in-ground or drip systems best meet drought-planning goals by maximizing water use efficiency.
