Box 1. Sustainable Development Goals related to fruit and vegetables SDGs 2 3 Health benefits of fruit and vegetables Harness the goodness Fruit and vegetables have multiple health benefits. They strengthen the immune system, combat malnutrition and help prevent non-communicable diseases. SDGs 2 3 Diversified diet and a healthy lifestyle Live by it, a diverse diet Adequate amounts of fruit and vegetables should be consumed daily as part of a diversified and healthy diet. SDGs 2 8 12 13 14 15 Food loss and waste Respect food from farm to table Fruit and vegetables are worth more than their price. Maintaining their quality and assuring their safety across the supply chain, from production to consumption, reduces losses and waste and increases their availability for consumption. Innovate, cultivate, reduce food loss and waste Innovation, improved technologies and infrastructure are critical to increase the efficiency and productivity within fruit and vegetable supply chains to reduce loss and waste. SDGs 1 2 12 15 Sustainable value chains Foster sustainability Sustainable and inclusive value chains can help increase production, and help to enhance the availability, safety, affordability and equitable access to fruit and vegetables to foster economic, social, and environmental sustainability. SDGs 1 2 3 4 5 8 11 12 15 Highlighting the role of family farmers Growing prosperity Cultivating fruit and vegetables contributes to a better quality of life for family farmers and their communities. It generates income, creates livelihoods, improves food security and nutrition, and enhances resilience through sustainably managed local resources and increased agrobiodiversity. 4 Fruit and vegetables – your dietary essentials

Trade policies have also promoted the influx of cheap, imported fruit and vegetables to the detriment of locally produced, indigenous varieties.
