More spatially-explicit trade analyses:the development of a pixel-to-consumer model for
Brazilian farming production
8/13/2019 Godar Javier
2/18
(Land) footprint analyses lack a detailed spatial connection between
production regions and final consumers.
Distortion of causal links between consumers choices and the environment
Errors in footprint calculations because env. impacts are site-specific (spatialvariability) while we use global or national averages (yields, C, WF index)
Impacts in specific regions remain invisible to consumers
This hampers our capacity to:
Allocate consumer responsibilities, accountability of governments/producersInclude externalities in the prize of traded goods
Understand mechanisms for improved efficiency
Inform policies

WHITOUT A SPATIAL DIMENSION? Geography matters!
WHAT LAND FOOTPRINT REALLY MEANS?....
For agricultural land: Europe is net importing large amounts of embodiedland Brazil (19 million ha) (Friends of the Earth Europe, 2013)
A cup of coffee has a land footprint of 4.3 m2

A PIXEL TO CONSUMER MODEL (4)
1.a Apparent consumption, re-exports: Products consumed in a country originate
in proportional shares from the country's imports and domestic production (Kastneret al, 2011). The exporting municipalities are treated as countries.

4- Modeling consumption
SEI tool: Resources and Energy Analysis Programme (REAP). REAP generatesecological, carbon and greenhouse gas at municipal, regional and national scales.
Data on emissions and land/resources required for production are allocated fromthe generating sector to the goods or services produced through the MRIO.

FINAL REMARKS
The model is in the process of further automatization for easy replicability(GRASS+R).
At the end this is about integrating well-consolidated disciplines:
The study of farming production dynamics
Environmental impact assessments
Trade analysisConsumption footprinting
Exports data at fine scales not generally available in most countries, but there isgood tracking-traceability of goods for tax/health purposes We need to demand
better trade data and provide resources to increase data standards.

CURRENT STATUS AND FUTURE DIRECTIONS
-Trade model just finished for all crops, code implemented in R andGRASS.
-Ongoing calculation of environmental impacts.
-Analyses and link to policies in 2014
-Several decisions to take:
-Which amortization time?-Crop substitution-Socio-economic impacts?-Integration with REAP, how?-Move to other countries.
-What can MRIO add to the methodology?-Automatization of several steps (LP)-Help!
