“…This focus on protecting natural resources and ecosystems remains until today [7,59], as confirmed also by the majority of articles connecting sustainable agriculture to environmental issues. Environmental protection in agriculture therefore represents one major strand of articles: The predominant lines of argumentation include ecological or ecosystem approaches to agricultural areas, such as studies on soil quality [60,61] and nutrient management [62,63]; environmental best agricultural practices, such as conservation agriculture [64,65], (eco)agroecology and agroecosystems [66][67][68], agrobiodiversity and agroforestry [69,70], low-input agriculture [7,71], alternative fertilization [72], and, finally, plant protection methods [73] as well as improved resource management (such as of energy and water) [60]. While often not directly connected to sustainable agriculture, resilience approaches to agriculture are a closely related topic.…”
