a The annual mean trends of NDVI in the buffer zones of the project and reference areas, with the red vertical line representing the year 2012. b The annual site-based NDVI differences between each of the 36 project sites and their corresponding reference areas, as represented by blue dots for each year. The red line across the plot represents the mean of these differences across all projects. c The average treatment effect on the treated for individual projects’ buffer zones estimated by difference-in-difference regression, where the whiskers extending above and below each point indicate the 95% confidence interval.
