Life Cycle Assessment (LCA) in Protected Agriculture: Methodological Inconsistencies Hinder Environmental Impact Clarity

Inconsistent methodologies and assumptions in Life Cycle Assessments (LCA) for protected agriculture obscure a clear understanding of its environmental impact.

Horticulturae · 2023

Key Findings

01Significant heterogeneity exists in LCA methodologies and assumptions used for protected agriculture.
02The environmental benefits of protected agriculture are highly context-dependent, particularly influenced by climate.
03Climate change significantly impacts crop yields and resource inputs/outputs (water, energy, carbon emissions).
04Protected agriculture can offer solutions for high-yield, high-quality crop production in extreme climates.
05Integration of circular bioeconomy strategies can mitigate identified environmental trade-offs.

Application

Design takeaway

How to apply

When undertaking a design project involving protected agriculture, conduct a thorough Life Cycle Assessment (LCA) using a well-defined and consistent methodology, and explore opportunities to incorporate waste reduction, resource recycling, and renewable energy sources.

Project actions

01When researching environmental impacts, be explicit about the methodology used for Life Cycle Assessment (LCA).
02Consider the specific environmental context (climate, local resources) when proposing design solutions for agricultural systems.
03Investigate how circular economy principles can be applied to reduce waste and resource consumption in your design.

Method & Evidence

AimTo identify trends, methodological inconsistencies, and future research directions in the application of Life Cycle Assessment (LCA) to protected agriculture.

MethodBibliometric and systematic review

ProcedureResearchers conducted a bibliometric analysis to track scientific productivity and research trends, followed by a systematic review of existing LCA studies on protected agriculture. This involved scrutinizing methodological choices across all phases of the LCA process (objective/scope, inventory, impact assessment, interpretation) and summarizing reported environmentally friendly practices and challenges.

ContextProtected agriculture (e.g., greenhouses, vertical farms)

Variables

IV["Methodology of LCA (e.g., scope, inventory, impact assessment, interpretation)","Context of protected agriculture (e.g., climate, location)"]

DV["Environmental impact assessment results","Identification of environmentally friendly practices","Identification of methodological challenges"]

CV["Type of protected agriculture system","Specific crop being grown"]

Strengths & Limitations

Strengths

+Comprehensive bibliometric and systematic review approach.
+Identifies key trends and limitations in a specific research area.
+Provides clear recommendations for future research and practice.

Limitations

The heterogeneity of LCA methodologies means that direct comparisons between studies can be challenging, and the findings may not be universally applicable without careful consideration of the original study's context and assumptions.

Reliability & validity

The reliability of the findings is strengthened by the systematic review methodology, which aims for comprehensive coverage and consistent analysis. Validity is supported by the dual approach of bibliometric and systematic review, providing both quantitative trends and qualitative insights into methodological rigor. However, the inherent heterogeneity of the reviewed studies introduces potential limitations to the generalizability of specific findings.

Think critically

Given the methodological inconsistencies in LCA for protected agriculture, how can designers ensure they are making truly informed decisions about environmental sustainability, and what steps can be taken to promote greater standardization in the field?

Design Principles

"Context-aware environmental impact assessment and circularity integration are essential for sustainable design in protected agriculture."

For designers and engineers working on agricultural systems, understanding the true environmental footprint is crucial for making informed decisions. Inconsistent LCA data makes it difficult to compare different approaches, identify the most sustainable solutions, and effectively communicate environmental benefits or drawbacks to stakeholders.

What This Means for Your Design

Studies looking at how 'green' farming methods like greenhouses are for the environment often use different ways to measure things, making it hard to compare them. The actual environmental benefit depends a lot on where the farm is and the weather. Using ideas from the circular economy can help make these farms more eco-friendly.

How to use in your project

1.Reference this study when discussing the importance of Life Cycle Assessment (LCA) in evaluating the environmental impact of your design project.
2.Use the findings on context-dependency to justify design choices that are tailored to specific environmental conditions.
3.Incorporate the concept of circular bioeconomy strategies as a potential area for design improvement or innovation.

Paragraph starter

This research highlights the critical need for standardized methodologies in Life Cycle Assessment (LCA) when evaluating protected agriculture systems, as current inconsistencies obscure a clear understanding of their environmental impact. The study emphasizes that the sustainability of these systems is highly context-dependent, particularly influenced by climate, and suggests that integrating circular bioeconomy principles can effectively mitigate environmental trade-offs. Therefore, any design project aiming for environmental sustainability in agriculture must rigorously apply consistent LCA practices and incorporate circular design strategies.
