‡

Sample sizes smaller than 996 reflect both missing values and exclusion of obvious errors, such as years of schooling greater than age and implausible reports of land assets.

#

Households in intervention villages where the concept of REDD+ had not yet been introduced were not asked whether they had heard of REDD+, in order to avoid raising concerns or generating confusion about the intentions of implementing organizations.
