It requires close attention to the land itself and the crops, rather than the standard mode of farming which is to plant cash crops at the highest yield possible.
Organic farming has long been considered more environmentally friendly than intensive, conventional farming. Although the scientists found the data is limited, they concluded that many high-yield systems are less damaging to the environment and use less land.
Main article: Terrace agriculture In agriculturea terrace is a leveled section of a hilly cultivated area, designed as a method of soil conservation to slow or prevent the rapid surface runoff of irrigation water.
The human landscapes of rice cultivation in terraces that follow the natural contours of the escarpments, like contour ploughingare a classic feature of the island of Bali and the Banaue Rice Terraces in Banaue, IfugaoPhilippines.
Remove competing plants from the crop growing area Herbicide spray Allows more energy to be transferred to the crop Reduces biodiversity and may have harmful effect on health Remove animals that feed on the crop Pesticide spray Prevents energy being transferred from the crop to consumers Reduces biodiversity and may poison helpful organisms Keep animals indoors Reduces energy transferred to environment so more energy available for growth Increased risk of disease, lower quality product, ethical concerns The effects of insecticides Some insecticides don't break down quickly.
This is where, through science, a tomato can have a gene from fish added to it to make it have a longer shelf life. However, while total yield per acre is often increased dramatically, yields of any single crop often diminish. In Peruthe Inca made use of otherwise unusable slopes by building drystone walls to create terraces.
