A method for calculating land degradation neutrality.

Area of Science:

• Environmental Science
• Sustainable Land Management
• Ecology

Background:

• The United Nations Convention to Combat Desertification (UNCCD) introduced Land Degradation Neutrality (LDN) to address global land degradation.
• LDN seeks to maintain or enhance land quality by balancing gains and losses over time.
• Quantifying this balance requires robust methodologies for assessing land quality.

Purpose of the Study:

• To develop a mathematical model for calculating and redressing land degradation.
• To provide a tool for quantifying the balance between land quality gains and losses.
• To establish a stable and scalable method for assessing land degradation.

Main Methods:

• A mathematical model was developed to calculate a proxy parameter for land quality.
• The model utilizes a set of land quality indices and correlation coefficients.
• It compares initial and degraded land conditions to determine necessary gains for neutrality.

Main Results:

• The model demonstrated stability within land quality index values of 1 and 2, and correlation coefficients from 0 to 1.
• A proxy parameter effectively represents land quality.
• The model successfully calculates the gains needed to achieve land degradation neutrality.

Conclusions:

• The developed mathematical model is a stable, scalable, and user-friendly tool for assessing land degradation.
• It provides a quantitative method to support Land Degradation Neutrality goals.
• The model can be applied across different scales for effective land management.
