Scientists and development experts across the globe are racing to increase food production by 50 percent over the next two decades to feed the world’s growing population, yet many doubt their chances despite a broad consensus that enough land, water and expertise exist.

The number of hungry people in the world rose to 1.02 billion this year, or nearly one in seven people, according to the United Nations Food and Agriculture Organization, despite a 12-year concentrated effort to cut the number.

Agronomists and development experts who gathered in Rome last week generally agreed that the resources and technical knowledge were available to increase food production by 50 percent in 2030 and by 70 percent in 2050 — the amounts needed to feed a population expected to grow to 9.1 billion in 40 years.

Sandseter began observing and interviewing children on playgrounds in Norway. In 2011, she published her results in a paper called “Children’s Risky Play From an Evolutionary Perspective: The Anti-Phobic Effects of Thrilling Experiences.” Children, she concluded, have a sensory need to taste danger and excitement; this doesn’t mean that what they do has to actually be dangerous, only that they feel they are taking a great risk. That scares them, but then they overcome the fear. In the paper, Sandseter identifies six kinds of risky play: (1) Exploring heights, or getting the “bird’s perspective,” as she calls it—“high enough to evoke the sensation of fear.” (2) Handling dangerous tools—using sharp scissors or knives, or heavy hammers that at first seem unmanageable but that kids learn to master. (3) Being near dangerous elements—playing near vast bodies of water, or near a fire, so kids are aware that there is danger nearby. (4) Rough-and-tumble play—wrestling, play-fighting—so kids learn to negotiate aggression and cooperation. (5) Speed—cycling or skiing at a pace that feels too fast. (6) Exploring on one’s own.

This last one Sandseter describes as “the most important for the children.” She told me, “When they are left alone and can take full responsibility for their actions, and the consequences of their decisions, it’s a thrilling experience.”

the final irony is that our close attention to safety has not in fact made a tremendous difference in the number of accidents children have.
