Portugal is one of the most vulnerable countries in Europe to climate change. Straddling the Mediterranean and eastern Atlantic regions, it’s part of a climate change hot spot. Some of the biggest fuels are shrubs. One study found that shrubland covers 1.6 million hectares in Portugal—about 18 percent of the nation’s land area. And those shrubs are gaining ground. That’s because, for decades, people have been moving out of rural communities such as the one Tommy Ferreira lives in.
