Harnessing emerging technologies to reduce Gulf hypoxia

Precision farming enabled by big data and gene-editing technologies are accelerating progress toward increasing nitrogen-use efficiency. However, farmer engagement, public–private partnerships and sound public policies are critical to harness the potential of such technologies to reduce hypoxia in the Gulf of Mexico.
