One-third of global protected land is under intense human pressure

Protected yet pressured

Protected areas are increasingly recognized as an essential way to safeguard biodiversity. Although the percentage of land included in the global protected area network has increased from 9 to 15%, Jones et al. found that a third of this area is influenced by intensive human activity. Thus, even landscapes that are protected are experiencing some human pressure, with only the most remote northern regions remaining almost untouched.

In an era of massive biodiversity loss, the greatest conservation success story has been the growth of protected land globally. Protected areas are the primary defense against biodiversity loss, but extensive human activity within their boundaries can undermine this. Using the most comprehensive global map of human pressure, we show that 6 million square kilometers (32.8%) of protected land is under intense human pressure. For protected areas designated before the Convention on Biological Diversity was ratified in 1992, 55% have since experienced human pressure increases. These increases were lowest in large, strict protected areas, showing that they are potentially effective, at least in some nations. Transparent reporting on human pressure within protected areas is now critical, as are global targets aimed at efforts required to halt biodiversity loss.

Agroecology is Advancing Around the Globe. Will the U.S. Take Part?

With its strong focus on social change for small farmers, agroecology is going mainstream worldwide, but the American food movement has yet to catch up.

Earlier this month, the United Nation’s Food and Agriculture Organization (FAO) held the 2nd International Symposium on Agroecology at its headquarters in Rome. The gathering attracted almost 800 participants, with representatives from 72 governments and 350 “non-state actors,” including civil society, academia, and the private sector. Farmers from Senegal, academics from the U.S., French parliamentarians, and staff of CropLife International, among others, gathered to debate the FAO’s claim of the urgent need to “scale up” agroecology as a means of achieving a more sustainable food system.

The symposium, hosted by the preeminent global institution on food issues, suggests that agroecology may finally be moving out of the margins. And it’s in the process of being mainstreamed.

Yet here in the U.S., it’s a different story. In fact, the word is rarely heard, even among people concerned with both agriculture and ecology. Instead, advocates—and the food industry—use the words organic, sustainable, and regenerative. And while some seem to use agroecology as an umbrella term that encompasses all of these practices, it’s more complex than that.

Shifting Language

All the above-mentioned terms share a commitment to food production without negative impacts on the environment. What makes agroecology different, potentially, is the combination of its scientific bona fides and its rootedness in the practices and political organization of small-scale food producers from across the globe. The former—as seen in multiple scientific elaborations of agroecology’s principles, like improved soil health, crop rotation, and diversification—is complemented by the latter, which gives agroecology meaning beyond the combination of “ecological” and “agriculture.”

California Will Require Solar Power for New Homes

SACRAMENTO — Long a leader and trendsetter in its clean-energy goals, California took a giant step on Wednesday, becoming the first state to require all new homes to have solar power.

The new requirement, to take effect in two years, brings solar power into the mainstream in a way it has never been until now. It will add thousands of dollars to the cost of home when a shortage of affordable housing is one of California’s most pressing issues.

That made the relative ease of its approval — in a unanimous vote by the five-member California Energy Commission before a standing-room crowd, with little debate — all the more remarkable.

State officials and clean-energy advocates say the extra cost to home buyers will be more than made up in lower energy bills. That prospect has won over even the construction industry, which has embraced solar capability as a selling point.
