Authors, experts, fieldwork, contributors, acknowledgements

Document authors, contributors, and Indigenous advisors

Authorship of this methodology has been difficult to assign properly, as many contributors have worked on different aspects of the design. We have opted for a formal scientific authorship list, a contributor listing, and a piloting practitioner list — as we feel the grassroots practitioners have contributed significantly by proving the model in practice, even if they never participated in writing.

It is important to use it to demonstrate equitable and accurate authorship of scientific work. But, in the case of this methodology, it was quite difficult, as there were so many disciplines, contributors, and even definitions of 'science'. For clarity and credit, we've opted for the following approach.

Multicategory authorship

Authors fall into one or more of four categories:

1. Direct authors of the methodology as per traditional academic criteria.
2. Indigenous or local leaders who are practitioners, field experts and piloting sites, advising on the practice guide, informing methodology creation by application and piloting feedback, or independently teaching its core tenets.
3. Collaborators and acknowledgements, including multidisciplinary scientists, practitioners, experts, and peers. Some of whom do not endorse this work, but provided foundational scientific work.
4. Reviewers who have publicly commented on or otherwise informed its development without direct endorsement

Notes on authorship:

• This methodology has been informed by exposure to traditional ecological knowledge (TEK) from several Indigenous groups, but is not directly attributable to one group in particular. We have chosen to cite individual contributing Indigenous advisors below, and removed any plant knowledge that may require Nagoya protocols.
• In some ways, funders are authors, as what gets funded gets produced. In that spirit, Naturatech LAC quite obviously contributed funding, peer support, applied science advising, and went far beyond traditional funders in that regard. Their funders, BID Labs Colombia made this possible. Additional research was funded by Bioversity/CIAT and the Institute of Plant Sciences.
• This is a living document and the author list is expected to expand as the methodology is intentionally stacked, different authors might work on different layers. We've outlinked to component layers where possible.

Direct methodology authors

Authors listed in alphabetical order. Included according to compliance with ICMJE authorship/contributorship criteria. Note: given the scope of the topics in the methodology, we are using a contributor/guaranteur model and including authors who contributed substantial writing and/or intellectual basis for core content.

Note: All contributing authors for an academic citation have been included according to ICMJE authorship/contributorship criteria. However, we find these criteria to be insufficient for the type of work this methodology represents.

Practitioners, field experts, and piloting sites

Collaborators

Technical advisors and negotiators are listed in alphabetical order. Contributed intellectually to the work without meeting formal ICMJE authorship/contributorship criteria. Note: there are strong debates in various fields as to some of the technical decisions in this protocol, and contributors should not be assumed to endorse all aspects of the protocol, which is extensive and multidisciplinary.
