Agri-footprint - Bugs & Issues

Agri-footprint 5.0 and Agri-footprint 6.0

We believe that making the agri-food sector and society more sustainable and healthier begins with accurate and clear information. To facilitate this we developed the LCA-database Agri-footprint. The first version of the database has been released in 2014, followed by yearly updates. Agri-footprint is under continuous development and we are always looking for opportunities to enhance, extend and improve the database. Inevitably, the database contains certain 'bugs & issues'. Our Data & Model team is right on top of these flaws and they are making an effort to solve every issue.

We are convinced that transparency is essential in the development of sustainable agri-food chains, which is why we want to be open about the current 'bugs & issues' in Agri-footprint. Below you find an overview of the 'bugs & issues' related to Agri-footprint 5.0 and 6.0 (which is available in SimaPro 9.4), including the solution we envision. And of course, please reach out to us if you want to raise any bug, issue or shortcoming you encountered.

Solution

Market mixes

For market mixes, all transport movements of each transport mode for moving mix components to the market mix country are aggregated into one default movement for that mode, neglecting differences in e.g. vehicle size and fuel type used. This causes misrepresentation in transport emissions, particularly for long distances.

This has been adapted for Agri-footprint 6.1, which will be available in SimaPro beginning of October 2022

Crude palm oil, crude peanut oil, crude maize germ oil, co-products and derivative products

Prices for palm kernel, crude peanut oil and maize germ meal extracted are wrong, causing economic allocation for the impact to main products to be too low and the impact for the co-product to be too high.

This has been adapted for Agri-footprint 6.1, which will be available in SimaPro beginning of October 2022
Dutch feed compounds containing soy bean hulls US soybean hulls are used in 3 feed compounds in the Netherlands This has been adapted for Agri-footprint 6.1, which will be available in SimaPro beginning of October 2022
Process: Calves <1 year ration, at farm/NL Economic The first "Grass, at farm/NL Economic" input should be grass silage This has been adapted for Agri-footprint 6.1, which will be available in SimaPro beginning of October 2022
Emissions for diesel use is not included in fishery activities (only the production of diesel is considered) The majority of the impact due to fuel combustion is currently not modelled. This leads to lower impact for fish and fish derived products in the database This has been adapted for Agri-footprint 6.1, which will be available in SimaPro beginning of October 2022
Market mixes of soybean expeller, rapeseed expeller and sunflower expeller Market mixes of these products are composed of the "meal" product This has been adapted for Agri-footprint 6.1, which will be available in SimaPro beginning of October 2022

Description of issue

Solution

Emissions from ammonia as fertilizer for USDA crops Upstream emissions of ammonia as fertilizer not included for USDA crops (which can be recognized with "US-**" in the database). This means that production of ammona is not included in the cultivation LCI's for USDA crops. Emissions from ammonia are included in the dataset. USDA crops will either be updated or excluded from Agri-footprint in the future.
Methane emissions USDA rice cultivation Methane emissions are not included in USDA rice cultivations. This significantly lowers the carbon footprint of this product USDA crops will either be updated or excluded from Agri-footprint in the future.
Lime inputs are not included for non-arable crops Lime as input is not included for all orchard cultivations in AFP. This means that production of lime is not included in the cultivation LCI's for orchards. Emissions from lime are included in the dataset. Arable crops do not have this problem Impact of lime will be added to new update of Agri-footprint. Impact of lime production is low and the amount of orchard type of crops in Agri-footprint is limited. 
Grass, at dairy farm/NL Phosphor emissions from manure and fertilizer mapped to the wrong compartment (soil instead of water) for roughages. Roughages in AFP include: grass, lucerne and fodder beet. The error has impact on eutrophication impact category only. Roughages will be updated and expanded in the next Agri-footprint update. 
Pea slurry, at processing/NL Economic Process of pea wet milling should be using pea flour as a raw material input, while now it uses dry peas. Will be updated in new Agri-footprint version.
Pea protein-concentrate, at processing/NL Economic Pea flour should be used for pea protein concentrate instead of the pea market mix. Will be updated in new Agri-footprint version.
Bleaching Earth Wrong transportation distance used for transporting bleaching earth. Bleaching earth used in small quantities for some oil refining processes. Distance will be corrected in new Agri-footprint version
Fertilizer splits for Belgium Fertilizer splits for Belgium based on data from Belarus. Although the amount of NPK used for Belgian cultivations are correct the total amount of NPK is expressed based on fertilizer splits that are available in Belarus. Most important difference is that Belarus uses urea as the most commonly used nitrogen fertilizer, wheras Belgium uses calcium ammonium nitrate more often and barely uses urea. This issue has impact on the type of fertilzer use and its production for Belgian cultivations only. It does not have impact on the total amount synthetic fertilizer use for Belgian cultivations and most of the emissions: laughing gas emissions (all related to the amount of N). The only type of emission the error has influence on is the amount of ammonia from fertilizer, since this determined by the type of fertilizer used (Tier 2 emission modelling.

Future plans for the Agri-footprint database

Our ambition for Agri-footprint is to offer a high quality agricultural database, which is mainly focused on feed and animal production, based on up-to-date data and state of the art methodologies. We want to offer a reliable and transparent database that can be used as a basis for any LCA work.

Agri-footprint 6.0 is now available in SimaPro 9.4. In August 2022 we will release Agri-footprint 6.1, which will be available through our Tool Platform and openLCA nexus.
