TMDL implementation in agricultural landscapes: a communicative and systemic approach

Area of Science:

• Agricultural Science
• Environmental Science
• Ecosystem Services

Background:

• Total Maximum Daily Load (TMDL) limits are increasingly applied to agricultural watersheds.
• Reducing non-point source pollution often requires land-use changes beyond annual crop management.
• Barriers exist for adopting perennial crops and other necessary land-use modifications.

Purpose of the Study:

• To present a novel strategy for voluntary land-use change to meet TMDL goals.
• To create economic incentives for landowners through multifunctional agriculture (MFA).
• To introduce the Communicative/Systemic Approach (C/SA) for MFA landscape design.

Main Methods:

• Developing new economic enterprises focused on multifunctional agriculture (MFA).
• Utilizing the Communicative/Systemic Approach (C/SA) with a GIS-based spatial modeling framework.
• Facilitating stakeholder deliberation and collaborative design of MFA landscapes.

Main Results:

• MFA can generate new revenue streams to finance land-use changes.
• C/SA systematically assesses tradeoffs and synergies in MFA landscape design.
• The approach aligns stakeholder interests for effective TMDL implementation.

Conclusions:

• A strategy combining MFA and C/SA can accelerate TMDL implementation.
• Voluntary participation driven by economic opportunities is key to land-use change.
• Integrated landscape design and stakeholder collaboration are essential for meeting environmental goals.
