Food System That Fails Poor Countries Needs Urgent Reform, Says UN Expert

According to a UN special rapporteur, a loss of agrobiodiversity, accelerated soil erosion, and pollution of fresh water from the overuse of chemical fertilizers resulting from the green revolution should be replaced by agroecology—a range of techniques that include intercropping, the use of manure and food scraps as fertilizer, and agroforestry (planting trees). This approach is more environmentally friendly and contributes to both diversified diets and improved nutrition. Although easier to implement on smaller-sized farms, agroecology is also applicable to larger operations.
