As a concept, agroecology was proposed over a century ago as a framework for more sustainable farming systems. Agroecology seeks to reduce our dependency on fossil fuel (petrol, gas), to reduce pollution of the environment and to mitigate the effects of climate change. It is based on principles that collectively aim to increase the autonomy and the resilience of the agroecosystem: recycling biomass, enhancing soil biotic activity through better management of organic matter, minimizing nutrient losses from the agroecosystem, increasing energy efficiency, increasing species and within-species diversity, and enhancing beneficial interactions and synergisms within agroecosystems (Altieri, 2015).
