Trase Supply Chains

Trase is a data-driven transparency initiative that maps the international trade and financing of agricultural commodities, providing tools that enable companies, financial institutions and governments to address tropical deforestation.

Reconstructing Ecological Niche Evolution via Ancestral State Reconstruction with Uncertainty Incorporated

Hannah Owens, Vivian Ribiero, Erin Saupe, Marlon E. Cobos, Peter Hosner, Jacob Cooper, Abdallah Samy, Vijay Barve, Narayani Barve, Carlos Muñoz & A. Townsend Peterson
Reconstructing ecological niche evolution can provide insight into the biogeography and diversification of evolving lineages. However, comparative phylogenetic methods can infer the history of ecological niche evolution inaccurately because (1) species’ niches are often poorly characterized; and (2) phylogenetic comparative methods rely on niche summary statistics rather than full estimates of species’ environmental tolerances. Here we propose a new framework for coding ecological niches and reconstructing their evolution that explicitly acknowledges and incorporates the uncertainty...

Modelled annual average percentage yield loss due to ozone damage for four global staple crops, 2010-2012 version 2

K. Sharps, G. Mills, D. Simpson, H. Pleijel, M. Frei, K. Burkey, L. Emberson, J. Uddling, M. Broberg, Z. Feng, K. Kobayashi & M. Agrawal
Modelled average percentage yield loss due to ground-level ozone pollution (per 1 degree by 1 degree grid cell) are presented for the crops maize (Zea mays), rice (Oryza sativa), soybean (Glycine max) and wheat (Triticum aestivum) for the period 2010-2012. Data are on a global scale, based on the distribution of production for each crop, according to the Food and Agriculture Organisation’s (FAO) Global Agro-Ecological Zones (GAEZ) crop production data for the year 2000. Modelled...

SEI-PCS Argentina crop commodities methodology version 1.1

This document describes the data and methods that Trase used to map the supply chain for Argentinian soy and corn commodities.

SEI-PCS Paraguay corn v1.0 supply chain map: Data sources and methods.

Trase maps supply chains for agricultural commodities, making it possible to link products and supply chain actors with specific areas of production and associated sustainability risks and opportunities. It uses an approach called Spatially Explicit Information on Production to Consumption Systems (SEI-PCS) as the basis for this work (see our manual for more detail). This document describes the data and methods that Trase used to map the subnational supply chain for Paraguayan exports of corn...

Data from: Disentangling the pathways of land use impacts on the functional structure of fish assemblages in Amazon streams

Rafael P. Leitão, Jansen Zuanon, David Mouillot, Cecília G. Leal, Robert M. Hughes, Philip R. Kaufmann, Sébastien Villéger, Paulo S. Pompeu, Daniele Kasper, Felipe R. De Paula, Silvio F. B. Ferraz & Toby A. Gardner
Agricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these impacts operate through multiple pathways and at several spatial scales. This complexity undermines the development of more effective management approaches, and illustrates the need for more in-depth studies to assess the mechanisms that determine changes in stream biodiversity. Here we present results of the most comprehensive multi-scale assessment of the biological condition of streams in the...

COP26 must commit to eliminating deforestation

Vivian Ribeiro
World leaders attending the UN climate talks in Glasgow must commit to stopping commodity-driven deforestation if they are to prevent climate catastrophe.

Data from: Impacts of dead-wood manipulation on the biodiversity of temperate and boreal forests - A systematic review

Jennie Sandström, Claes Bernes, Kaisa Junninen, Asko Lohmus, Ellen Macdonald, Jörg Müller & Bengt Gunnar Jonsson
Dead wood (DW) provides critical habitat for thousands of species in forests, but its amount, quality and diversity have been heavily reduced by forestry. Therefore, interventions aiming to increase DW might be necessary to support its associated biodiversity, even in protected forests, which may be former production forests. Our aim was to synthesise the current state of knowledge drawn from replicated experimental studies into solid quantitative evidence of the effects of DW manipulation on forest...

Commodity deforestation exposure and carbon emissions assessment

This document explains how Trase calculates metrics that reflect deforestation for commodity production, related greenhouse gas emissions, and the exposure of supply chain actors to those impacts.

Accounting for environmental variation in co‐occurrence modelling reveals the importance of positive interactions in root‐associated fungal communities

Nerea Abrego, Tomas Roslin, Tea Huotari, Ayco J.M. Tack, Björn D. Lindahl, Gleb Tikhonov, Panu Somervuo, Niels Martin Schmidt, Otso Ovaskainen & Ayco J. M. Tack
Understanding the role of interspecific interactions in shaping ecological communities is one of the central goals in community ecology. In fungal communities, measuring interspecific interactions directly is challenging because these communities are composed of large numbers of species, many of which are unculturable. An indirect way of assessing the role of interspecific interactions in determining community structure is to identify the species co-occurrences that are not constrained by the environmental conditions. In this study, we...

Assessing tropical deforestation risk in Germany’s agricultural commodity supply chains

Peta rantai pasok ‘SEI-PCS Indonesia palm oil v1.2’: Sumber data dan metode.

Dokumen ini menjelaskan data dan metode yang digunakan Trase untuk memetakan rantai pasok minyak kelapa sawit Indonesia dengan menggunakan versi model yang dinamakan “SEI-PCS Indonesia palm oil v1.2”.

Scaling up gas and electric cooking in low- and middle-income countries: Climate threat or mitigation strategy with co-benefits?

Emily Floess, Andrew Grieshop, Elisa Puzzolo, Daniel Pope, Nicholas Leach, Christopher J. Smith, Annelise Gill-Wiehl, Katherine Landesman & Robert Bailis
Nearly three billion people in low- and middle-income countries (LMICs) rely on polluting fuels, resulting in millions of avoidable deaths annually. Polluting fuels also emit short-lived climate forcers and greenhouse gases (GHGs). Liquefied petroleum gas (LPG) and grid-based electricity are scalable alternatives to polluting fuels but have raised climate and health concerns. Here, we compare emissions and climate impacts of a business-as-usual household cooking fuel trajectory to four large-scale transitions to gas and/or grid electricity...

Data from: Is environmental legislation conserving tropical stream faunas? a large-scale assessment of local, riparian and catchment-scale influences on Amazonian stream fish

Cecília G. Leal, Jos Barlow, Toby Gardner, Robert M. Hughes, Rafael P. Leitão, Ralph Mac Nally, Philip R. Kaufmann, Silvio F. B. Ferraz, Jansen Zuanon, Felipe R. De Paula, Joice Ferreira, James R. Thomson, Gareth D. Lennox, Eurizângela P. Dary, Cristhiana P. Röpke, Paulo S. Pompeu & Toby A. Gardner
1.Agricultural expansion and intensification are major threats to tropical biodiversity. In addition to the direct removal of native vegetation, agricultural expansion often elicits other human-induced disturbances, many of which are poorly addressed by existing environmental legislation and conservation programmes. This is particularly true for tropical freshwater systems, where there is considerable uncertainty about whether a legislative focus on protecting riparian vegetation is sufficient to conserve stream fauna. 2.To assess the extent to which stream fish...

A practical approach to measuring the biodiversity impacts of land conversion

América P. Durán, Jonathan M. H. Green, Christopher D. West, Piero Visconti, Neil Burgess, Malika Virah-Sawmy & Andrew Balmford
1. Further progress in reducing biodiversity loss relies on the improved quantification of the connections between drivers of habitat loss and subsequent biodiversity impacts. To this end, biodiversity impact metrics should be able to report linked trends in specific human activities and changes in biodiversity state, accounting for both the ecology of different species, and the cumulative effects of historical habitat losses. These characteristics are not currently captured within a single metric. 2. Here we...
