Delineate critical areas that require different crops and management practices.
Identify suites of suitable crops, crop rotations, and conservation practices for each management area.
Develop a landscape-scale precision-agriculture system.
Apply policies, education, and programs that address social and economic concerns related to the adoption and implementation of the land-scape-scale precision-agriculture systems.
Monitor and document the new system’s performance toward production and conservation goals.
Re-evaluate the system and make adaptive changes to improve its performance.
In summary, the important message from the above examples and guidelines is that the technology needed to implement a sustainable landscape vision of biofuel production exists and that the practices can already be implemented efficiently and economically.
