Across the United States, record quantities of corn and soybeans have been harvested in recent years. However, according Dr. David Gustafson of the International Life Sciences Institute Research Foundation, this trend may soon change. The combined and uncertain effects of climate change could have a devastating impact on grain yields in the US Midwest, with major global implications for food security. To address these rising threats, Dr. Gustafson and his colleagues propose a new, coordinated network of field research sites at which precise data on the performance of current and future crops, cropping systems, and farm-level management practices in the US Midwest could be gathered. Dr. Gustafson joins us to describe the plan.
Numerous studies have demonstrated the benefits of contact with nature for human well-being. However, despite strong trends toward greater urbanization and declining green space, little is known about the social consequences of such contact. Netta Weinstein, senior lecturer at Cardiff University, and her team used a nationally representative UK study to examine the relationships between social cohesion and exposure to nature. The interrelationships were complex, but the results indicate that, even when controlling for numerous possible confounds, nature exposure may account for meaningful amounts of variance in crime and perceived community well-being.
