One assumption, two observations and some guiding questions for the practice of agro-ecosystem health

The paper describes the features of agro-ecosystem health as a paradigm or framework to study and develop sustainable agricultural systems. It is posited that agro-ecosystem health research is undertaken in order to help people make better decisions with regard to managing the ecosystems in which they live and grow food. Agro-ecosystems can be viewed and interpreted from a variety of non-equivalent perspectives, and within each perspective, agro-ecosystems can be viewed and understood at different spatial and temporal scales. Therefore, whose perspective is taken into account in identification of constraints and priorities, and designing solutions will determine whether research and development efforts will lead to sustainable agricultural systems
