Global Biomass Flow Mapping Reveals Shifting Cropland Footprints
Category: Resource Management · Effect: Strong effect · Year: 2019
Detailed input-output modeling of biomass flows in the global food and agriculture sector can quantify consumption-based resource demands, highlighting shifts in environmental pressures across countries.
Design Takeaway
Quantify the physical resource flows and environmental impacts associated with your product's entire supply chain to identify key areas for sustainable intervention.
Why It Matters
Understanding the physical flow of biomass from production to consumption is crucial for identifying resource bottlenecks and environmental impacts within complex global supply chains. This insight enables designers and engineers to make more informed decisions regarding material sourcing, waste reduction, and the overall sustainability of their products and systems.
Key Finding
A detailed model of global biomass flows shows how consumption in different regions drives resource use, like cropland, across the world.
Key Findings
- The FABIO model provides a comprehensive, transparent, and flexible structure for organizing data on material flows within metabolic networks.
- It allows for tracing of biomass flows and associated environmental pressures along global supply chains with detailed product and country specificity.
- Analysis of cropland footprints revealed evolving consumption-based demand for plant-based and livestock-based food and nonfood products in China, the EU, and the USA.
Research Evidence
Aim: To develop and apply a multiregional input-output model in physical units to document and analyze the complex flows of agricultural and food products within the global economy, specifically to trace cropland footprints based on consumption.
Method: Input-Output Modeling
Procedure: The FABIO model was constructed using FAOSTAT statistics on crop production, trade, and utilization in physical units, combined with data on conversion efficiencies. This data was integrated into a balanced input-output framework covering 191 countries and 130 products from 1986 to 2013. The model was then applied to analyze consumption-based cropland demand evolution in China, the EU, and the USA.
Sample Size: 191 countries, 130 products
Context: Global Food and Agriculture Supply Chains
Design Principle
Map and analyze the physical flow of materials through global supply chains to understand and mitigate resource consumption and environmental impact.
How to Apply
When designing products that utilize agricultural or forestry-derived materials, investigate the origin and processing of these materials to understand their full resource footprint.
Limitations
The model relies on available statistical data, which may have inherent inaccuracies or gaps. Conversion efficiencies can vary significantly in practice.
