Perennials are crops which do not have to be planted every year. These crops can reduce the erosion of soil as well as nutrient runoff. The only problem right now is that these crops have low yields. Scientists and private organizations are working to resolve this problem. Developing perennial varieties of major food grain crops can help to feed the approximately 1 billion hungry people in the world. Shifting the trend of agriculturists from annual to perennial crops may be the answer to the food shortage problem in future. Take a look at some challenges faced by perennial crops:
Various techniques employed in sustainable farming such as drainage and crop rotation claim to work wonders to eliminate food scarcity. Pressure on food supplies is ever increasing with the increase in population but it is becoming far more impossible to meet the food needs. Sustainable farming seems to be a good solution that helps farmers to use land for the best of its capacity and eliminate food scarcity.
