This is the way

Are you able to find it on Google Maps? Having a hard time locating it. "Based on the results of this study, the Taklamakan Desert, although only around its rim, represents the first successful model demonstrating the possibility of transforming a desert into a carbon sink," Yung said.

A lot of the roads that cross the desert look like they're flanked by trees or by some kind scrubby grass mounds. This road is flanked by trees or bushes https://maps.app.goo.gl/JW3gxd8wxSiuwhnZ7

So to plant a row of trees a bulldozer has to level sand dunes. I somehow doubt the exhaust from this process is factored into the CO2 sink calculation.

We found that an 8T excavator that spent 11 hours and 3 minutes working, 1 hour and 6 minutes of which were idle, it used 89 litres of fuel and resulted in 237.4kgs of carbon emissions. 4 hours saved on that machine would be a total of 84kgs of carbon emissions on average.

> To determine the amount of carbon dioxide a tree can absorb, we combine average planting densities with a conservative estimate of carbon per hectare to estimate that the average tree absorbs an average of 10 kilograms, or 22 pounds, of carbon dioxide per year for the first 20 years.

As long as they're not taking all day for one tree, I think they'll be OK.

I wonder how the albedo has changed, and evaporation of water there.

That was my thought too Is it possible the trees can change the climate in the region? Can trees dampen regional water flux, seed clouds down range?

How much deforestation over the past decades has been reversed and is deforestation currently under control?

Per the article:

> China finished encircling the Taklamakan Desert with vegetation in 2024, and researchers say the effort has stabilized sand dunes and grown forest cover in the country from 10% of its area in 1949 to more than 25% today.

That tree carbon capture estimate is probably conservative here if planting trees achieved de-desertification and resulted a larger thriving ecosystem.

The main problem with attempts at reversing the damage is that forests aren't fungible.

An old growth forest has a rich, balanced ecosystem. Newly planted forests tend to be susceptible to catastrophic damage by various critters, as the species mix is much less complex, and their fauna and flora is relatively impoverished.
