Special issue: 'Organic farming and agroecology as a response to global challenges'—selected papers from the 2nd International GRAB-IT Workshop (GRAB-IT 2018), Anacapri, Italy, 26–27 June 2018, editorial.

Agroecological practices and circular economy approaches are at the core of a modern way of organic farming. To respond to the current challenges, the organic sector needs to strengthen its innovation efforts, not only to produce sufficient healthful, safe, and affordable food for a growing population, but also to meet the goals of developing circular food chains, minimizing food losses and food waste, guaranteeing a fair distribution of the added value produced among the actors, using renewable energy and recycled nutrients in an efficient way. The selected papers included in this special issue are a contribution to tackle these challenges and foster innovation in the organic food and farming sector. [ABSTRACT FROM AUTHOR]
