Nitrogen Crisis Meeting, Sept. 2015
Tackling the nitrogen crisis; what are the solutions?
Oxford Martin School, 18th September 2015.
Meeting overview
A broad, discipline-spanning symposium examining the nitrogen crisis, its severity and how we measure and monitor it. Innovations to alleviate the nitrogen crisis were explored; from changing agricultural practice, legume breeding, nodulation of cereals, cereal nitrogen use efficiency, through to engineering solutions such as expressing nitrogenase in mitochondria, synthetic symbioses and exploiting natural endophytes. How these relate to social and regulatory aspects of changing agricultural practice in both developing and well-developed countries was considered.
Themes considered
1. How bad is the nitrogen crisis?
2. Agricultural practices, their social and economic context
3. Engineering and natural solutions
4. Nitrogen use efficiency
