Greenhouse horticulture in the Mediterranean: Optimizing water, fertilizer, and plastic use for environmental and economic gains

Sustainability · 2024

Key Findings

01Fertigation management is a major water consumer, potentially reaching 11,283 m³/ha/year.
02Fertilizer leaching can contribute significantly to marine eutrophication (up to 27 kg N eq).
03Crop protection treatments pose a risk of terrestrial ecotoxicity (up to 130,037 kg 1,4-DCB).
04The use and disposal of plastic materials for infrastructure are significant environmental concerns.
05Greenhouse management and hired labor represent the largest economic cost components (up to 35% and 40% respectively).

Application

Design takeaway

How to apply

When designing or improving agricultural systems, conduct a thorough life cycle assessment to identify and address the most significant environmental and economic hotspots, such as water use, waste generation, and operational inefficiencies.

Project actions

01When researching a product, think about its entire life, from making it to throwing it away, to find the biggest problems.
02Consider both the environmental impact and the cost when designing solutions.

Method & Evidence

AimTo identify and quantify the environmental and economic hotspots within Mediterranean greenhouse horticulture to inform strategies for improving overall performance.

MethodLife Cycle Assessment (LCA) and Life Cycle Costing (LCC) applied to case studies.

ProcedureResearchers conducted a comparative analysis of four commercial greenhouse operations across Italy, Spain, Tunisia, and Turkey. They assessed the environmental impacts (water use, eutrophication, ecotoxicity) and economic costs (management, labor) throughout the product life cycle to pinpoint critical areas for improvement.

Strengths & Limitations

Strengths

+Combines environmental and economic assessment (LCA and LCC).
+Cross-country comparison provides broader insights.
+Identifies specific, quantifiable hotspots.

Limitations

It's hard to get exact data for every stage of a product's life, and real-world conditions can change results.

Reliability & validity

The use of established methodologies like LCA and LCC, combined with real-world case studies, lends credibility. However, the validity might be limited by the specific choices made in the LCA and the representativeness of the case studies.

Think critically

How might the specific climate and socioeconomic conditions of the Mediterranean Basin influence the generalizability of these findings to other regions or agricultural systems?

Design Principles

"Minimize resource consumption and waste throughout the product lifecycle by targeting high-impact areas identified through comprehensive assessment."

This research provides critical data for designers and engineers involved in agricultural technology and infrastructure. By identifying the most impactful areas for intervention, it guides the development of more resource-efficient and economically viable greenhouse systems, crucial for food security and environmental protection in a sensitive region.

What This Means for Your Design

Greenhouse farming in sunny places like the Mediterranean uses a lot of water and fertilizer, and creates plastic waste. Fixing these issues, along with managing costs better, can make the farms more eco-friendly and profitable.

How to use in your project

1.Use the methodology (LCA/LCC) as inspiration for your own project's impact assessment.
2.Reference the identified hotspots (water, fertilizer, plastic) as areas to investigate for your design problem.
