  • The Reactive Nitrogen “Wicked Problem”– critical nutrient, disastrous pollutant

    August 11, 2014

    Nobel Peace Prize recipient and Director of the Purdue University Climate Change Research Center, Dr. Otto Doering, recently gave a keynote speech where he highlighted his definition of Wicked Problems facing the globe and the US.

    In brief, he used US struggles regarding affordable health care and the debate regarding the Affordable Health Care Act as a prime example of a Wicked Problem. Regardless where one might stand politically on such an issue, it is clear that the issues of affordable health care and potential policy solutions are of great importance to many, with its tentacles reaching into vast and diverse sectors of our society. No clear consensus on how to solve the problem appears to be present, due to the complexities and interrelationships involved. In particular, solutions can be shown to result in a cascade of unknown consequences, either positive or negative, with individual stakeholders holding a diversity of economic, personal and social viewpoints. 

  • New Meta-Analysis Identifies Three Significant Benefits Associated With Organically Grown Plant-Based Foods

    July 11, 2014

    There have been four progressively rigorous meta-analyses published since 2009 focusing on differences in the nutritional quality and safety of organic versus conventional food. The latest comes out July 15, 2014 in the British Journal of Nutrition (BJN). I was the sole American scientist on the mostly European research team that produced the BJN paper:

  • Closing the Nutrient Loop

    July 2, 2014

    There are a number of sustainability issues getting a fair amount of attention these days: climate change, regional and local food systems, and soil health, to name a few. While this is obviously good, there are also issues that may be getting somewhat less attention than they deserve. And closing the nutrient loop is one of these.
