Continued and expanded agricultural production is required for global food security, but farmers’ intensive reliance on agrochemical, fossil-fuel and other purchased inputs has put the sustainability of production systems at risk. Excessive input-based modern agriculture has severely compromised the health of natural resources (soil, water and biodiversity) and the quality of our environment and food. Thus, there is an urgent need to rethink the choice of technology, practices, policies, and strategies to achieve sustainable crop production.
Agroecological approaches aim to diminish farmers’ dependence on external inputs as much as possible by mobilizing and invigorating the biological processes and potentials available in existing plants and the soil systems that support our crops. Empirical evidence shows that these objectives are achievable.
