Framework for measuring sustainable development in catchment systems.

Area of Science:

• Environmental Science
• Water Resource Management
• Sustainable Development

Background:

• Integrated catchment management balances environmental, economic, and social factors for sustainable resource use.
• Effective management requires indicators to assess complex catchment processes and resource management actions.
• The Driving-Forces--Pressure--State--Impact--Response (DPSIR) framework is a valuable tool for developing these indicators.

Purpose of the Study:

• To apply the DPSIR framework for identifying key catchment management issues.
• To develop a set of indicators for evaluating catchments in South Africa.
• To support sustainable development through informed decision-making in water resource management.

Main Methods:

• Utilized the DPSIR indicator framework to categorize catchment management components.
• Identified driving forces (natural conditions, development, economic activity).
• Analyzed pressures (water supply, demand, pollution), state (quantity, quality), and impacts (ecosystem, resource use value).

Main Results:

• Core indicators were identified within each DPSIR category.
• The framework allows for the evaluation of major catchment-based management issues.
• Key issues and a set of indicators for South African catchments were identified.

Conclusions:

• The DPSIR framework provides a robust structure for developing sustainable development indicators in catchment management.
• This approach is applicable for evaluating catchments and informing management strategies in South Africa.
• The developed indicators can aid in achieving sustainable benefits while protecting natural resources.
