n the past decade, researchers have clearly identified
the range of scenarios for food and agriculture and
identified the past impacts as well as the many
challenges we face. Accordingly, there is considerable
agreement about the nature and causes of these
challenges. The challenges are not only those of our
crops and animal husbandry but also those of our
soils, biodiversity, and water. However, given the
interpretations of past developments that are framed
by diverse values and world views, there has been less
accord about the best solutions.
