Protected agriculture (PA) refers to the use of technology to modify the natural environment (temperature, rainfall, humidity, wind, etc.) that surrounds a crop to harvest higher yields, of better quality, during an extended season. PA often employs cutting-edge technologies to enhance the productivity of commercial crops, as well as the quality and safety of agrifood products for greater profitability. Some examples of PA are floating covers, low tunnels, walking tunnels, and greenhouses.
