Save a Rainforest, Reduce Poverty

A new study disputes a widely-held assumption that protecting forest resources exacerbates poverty for people living nearby.

Instead, this novel research shows that saving rainforests and protecting land in national parks and reserves reduced poverty in Costa Rica and Thailand. The researchers looked at the long term impacts of poor people living near parks and reserves established in 1985 or earlier. From the abstract:

“As global efforts to protect ecosystems expand, the socioeconomic impact of protected areas on neighboring human communities continues to be a source of intense debate. The debate persists because previous studies do not directly measure socioeconomic outcomes and do not use appropriate comparison groups to account for potential confounders. We illustrate an approach using comprehensive national datasets and quasi-experimental matching methods. We estimate impacts of protected area systems on poverty in Costa Rica and Thailand and find that although communities near protected areas are indeed substantially poorer than national averages, an analysis based on comparison with appropriate controls does not support the hypothesis that these differences can be attributed to protected areas. In contrast, the results indicate that the net impact of ecosystem protection was to alleviate poverty.”

Coauthor and economist Paul J. Ferraro tells Georgia State University the results are counterintuitive:

“Most people might expect that if you restrict resources, people on average will be worse off.”

The authors speculate that conservation of biodiverse areas may help poor people through tourism and infrastructure, notably new roads providing new economic opportunities.

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
