Question

Quizplus · Accepted Answer

Using monoculture instead of polyculture farming is not a low-tech method for irrigation. Monoculture involves growing only one crop in an area, which is not a sustainable farming method and can lead to soil degradation and loss of biodiversity. The other options mentioned are all low-tech methods commonly used in developing countries for irrigation. Rainwater harvesting involves collecting rainfall and storing it for later use. Planting deep-rooted perennial crop varieties allows for better water absorption in the soil. Mulching fields involves covering the soil with a layer of organic material to reduce evaporation and retain moisture. Harvesting fog with fog catcher nets involves capturing water from fog, which is a common practice in areas with high fog occurrence but low rainfall.
