Modern science should focus on sustainable increases in land and water productivity, management of production risks caused by droughts, floods, pests, and on mitigation and adaption to climate change. Drought-tolerant and pest-resistant crop varieties, disease-resistant livestock, and high-yield agricultural production systems that use less water and capture nitrogen from the air are but a few examples of the kind of technologies needed.
