Sustainable Agroecosystems

In order to understand sustainable agriculture and implement it, we need to elucidate the feedbacks between ecosystem management options (e.g., tillage, cover cropping, green manuring, sustainable farming, and grazing), global change (e.g., elevated CO₂ and climate change), and biogeochemical cycling.

Hence, we need to unravel the complex interactions between plants (e.g., diversity, nutrient uptake, and root growth), soil (e.g, structure, texture and mineralogy), soil biota (e.g. fungi, bacteria, and earthworms), and the carbon and nitrogen cycles in agroecosystems across spatial and temporal scales. Furthermore, since agriculture is an human enterprise, not only biophysical aspects, but also social and economic dimensions of sustainable agriculture needed to be elucidated. One approach to do so is bio-economic modeling through which the sustainability of agricultural practices are holistically assessed.
