Background:

• Ambient air quality in Central Europe poses a potential threat to agroecosystem productivity.
• Existing knowledge gaps hinder a full understanding of the relationship between air pollution and ecosystem function.

Purpose of the Study:

• To highlight the need for developing, validating, and applying air pollutant exposure-plant response models.
• To explain the complex relationships between the chemical climate and ecosystem responses.
• To incorporate numerical terms for effective air pollutant exposure, considering matter, energy, and information fluxes.

Main Methods:

• Discussing a combined approach using empirical and mechanistic models.
• Integrating numerical terms for air pollutant exposure regimes.
• Accounting for fluxes of matter, energy, and information within ecosystems.

Main Results:

• The study outlines a framework for modeling the impact of air pollutants on agroecosystems.
• It emphasizes the necessity of quantitative models to link air quality to ecosystem productivity.
• The proposed approach allows for a comprehensive description of ecosystem structure and function under pollutant stress.

Conclusions:

• Developing robust air pollutant exposure-plant response models is essential for Central European agroecosystems.
• Such models are key to understanding and mitigating the adverse effects of air quality on agricultural productivity.
• The integration of empirical and mechanistic approaches offers a promising pathway for ecosystem management.
