Decision trees for SOC estimation and management to achieve LDN

Land degradation neutrality (LDN) is achieved if land degradation is avoided or reduced, and new degradation is balanced by reversing degradation elsewhere in the same land type through restoration or rehabilitation. 

The primary instrument for avoiding and reducing degradation is the application of sustainable land management, (SLM) approaches, and technologies. Because of its multifunctional roles and its sensitivity to land management, soil organic carbon (SOC) is one of the three global indicators for LDN, so predicting and monitoring change in SOC is vital to achieving LDN targets.

To optimize the use of limited resources to manage SOC using SLM to pursue LDN, the framework below guides the development, testing, and refinement of SOC assessment methods for application in SOC monitoring, to support the assessment of LDN achievement.

                                         Framework SOC

The following decision trees will guide efforts to predict change in SOC under alternative SLM practices, and monitor SOC change in response to SLM interventions, and thereby support decision-makers to pursue the right SLM interventions in the right locations, at the right time, at the right scale with the overall goal to increase or maintain SOC and improve soil health in support of LDN achievement.
