Half a century ago, MIT meteorology professor Edward Lawrenz famously posited that if a butterfly flaps its wings, it could ultimately trigger a tornado. The notion, which came to be known as the “butterfly effect,” aimed to illustrate how chain reactions in nature can be kicked off by unexpected events or phenomena, with unknowable consequences. Lawrenz would have found a fine case study for his work this week in events that started with a volcanic eruption in the South Pacific and led to dramatic results—political, social and economic—far away in Peru. Ten days ago, a volcano at the bottom of [...]
Anyone with even a sketchy understanding of the Cold War knows that it was a time not only of intense direct competition between the reigning superpowers, but also of grand schemes by both the U.S. and USSR for integrating their allies and clients into adversarial blocs, as well as for poaching the partners of the rival power—especially in the developing world—into their own camp. Throughout much of this era, the West regarded professions of neutrality among poorer countries with skepticism or even outright hostility. Beginning with the Eisenhower administration, the view took hold in Washington that non-alignment was just a [...]
For the past 60 years, a series of agricultural innovations have helped feed the world. New varieties of staple crops produced high yields. New fertilizers encouraged crop health. And improved agronomic methods helped farmers make the most of their resources. These new tools and practices became foundational to the production of agriculture in the U.S. and around the world, enabling marked increases in output and important reductions in rural poverty. But that productivity-centric model is no longer meeting global needs. Over the past decade, hunger has once again started to rise, bringing with it doubts about our long-term ability to [...]
