Beyond carbon-centric estimates: revisiting the interplay between hydroclimatic conditions and dryland forestation

In the global pursuit of climate mitigation, extensive tree planting initiatives have targeted the vast drylands. However, the carbon sequestration potential of forestation in these regions remains uncertain, primarily due to the oversight of crucial factors like vegetation-climate interactions. By revisiting the benefits of dryland forestation using comprehensive Earth System Modeling, we underscore the vital role of hydroclimatic factors in shaping the effectiveness of nature-based solutions, urging a reassessment of criteria for accurate carbon-centric estimates and sustainable global climate change mitigation strategies.
