Combating desertification in southern African rangelands is addressed by a new Decision Support System (DSS). This system integrates local and scientific knowledge to aid land users in restoration efforts.

Area of Science:

Environmental Science
Agricultural Science
Information Science

Background:

Desertification and bush encroachment are critical issues in southern African rangelands.
Restoration technologies often rely on indigenous knowledge but lack integration with scientific data.

Purpose of the Study:

To develop a user-friendly, computerized Decision Support System (DSS).
To integrate local and scientific knowledge for combating desertification.

Main Methods:

Utilized case studies from Namibia to combine qualitative and quantitative data.
Developed a DSS comprising two databases and an expert system.
Linked the DSS to national and international web resources for broader information access.

Related Experiment Videos

Main Results:

The DSS evaluates land user management practices and offers tailored advice.
Provides accessible information on agricultural and conservation technologies.
Facilitates informed decision-making for rangeland restoration.

Conclusions:

Integrating local and scientific knowledge in a DSS is effective for desertification control.
The developed DSS empowers land users with data-driven insights for sustainable rangeland management.
This approach enhances the success rate of restoration technologies in combating desertification.
