All farmers want to produce an abundance of high-quality produce on their land. Despite the prevailing belief that sustainable agriculture cannot produce enough food to feed the world, many studies show that small-scale, diversified, sustainable farms are often more productive per unit of land than large-scale, mono-cropped, conventional farms. Abundant yields are often achieved by inter-planting diverse crops together. This practice helps control pests and weeds, feeds the soil, and uses water efficiently.
