Protected agriculture (controlled environment agriculture) is the use of technology to modify the growing environment for crops to extend the growing period and increase yields. It can include greenhouses, shade nets or polytunnels. This technology is moderately expensive therefore it is used only for the cultivation of high-value crops and raising seedlings in winter.
