Life Cycle Assessment on Agricultural Production: A Mini Review on Methodology, Application, and Challenges

Area of Science:

• Agricultural Science
• Environmental Science
• Ecosystem Analysis

Background:

• Agricultural Life Cycle Assessment (LCA) is crucial for evaluating environmental impacts across agricultural systems.
• It supports the promotion of sustainable and green agricultural development by summarizing environmental effects.
• Agricultural LCA is increasingly utilized in agroecosystems for resource and environmental impact analysis.

Purpose of the Study:

• To discuss existing challenges in agricultural LCA.
• To recommend research priorities for scientific advancement and practical implementation.
• To enhance the robustness and effectiveness of agricultural LCA for decision-making.

Main Methods:

• Life Cycle Assessment (LCA) concept applied to agricultural systems.
• Analysis of environmental impact assessment index systems.
• Evaluation of LCA application across different agricultural production modes.
• Exploration of integrating LCA with other environmental models.

Main Results:

• Identified limitations in current agricultural LCA, including index system improvement needs and limited application scope.
• Highlighted the necessity for better integration of LCA with other models.
• Emphasized the need for regional heterogeneity databases and innovative methodologies for functional units.

Conclusions:

• Agricultural LCA is a vital tool for assessing environmental impacts and promoting sustainable agriculture.
• Addressing current challenges requires developing regional databases, innovative methodologies, and enhanced model integration.
• Improved agricultural LCA will support informed decision-making from farm to international levels for a sustainable agricultural future.
