Climate change, increasing food demand, decreasing natural resources and rapid degradation of most ecosystems are calling urgently for alternative farming practices. This virtual issue published by the journal Agronomy for Sustainable Development gathers 20 visionary reviews describing principles and applications of agroecological engineering. Key topics include climate-change resilient farming, food sovereignty, organic farming, weeds for bees, water management under drought, alternative pest management, ecological services for agriculture, cereal-legume intercropping, landscape engineering, and soil carbon and biodiversity.
