Public participation in science may deliver democratised understanding about what is happening on the land, but often struggles to account for who ultimately has the power to make decisions about land use. This is especially important in the study of agricultural systems, where actions taken by private farmland owners are the drivers that press environmental and social outcomes in the public interest. The power to make changes to agricultural practices often lies in the hands of land owners, rendering findings or recommendations from agriculture themed citizen science projects as disconnected from the levers of authority to make change. This is why a strategy for open land ownership data  is a crucial, overlooked piece of the puzzle when it comes to transformative open agri-environmental research.
When it’s clear who owns the land, one knows who to engage with to make changes, who is responsible for any action or misdeed, and who has controlling interests in landscape dynamics. Asking questions like “who benefits?” and “who decides?” introduces an awareness of social power into community science initiatives. Of all of the types of non-expert participation in science, a defining feature is how explicitly the varying approaches recognise and address power relations. For example, at one end of the spectrum is citizen science, defined by its enrollment of non-experts in the data collection phase of a predetermined research agenda most often limited to the biophysical sciences. For citizen science, engagement with power relations is mostly emergent, where the act of engaging a broader public in a research question leads to empowered citizens and new forms of data made newly accessible. At the other end of the power awareness spectrum is the Fals-Bordian participatory action research (PAR), where concerns of the dispossessed, marginalised and grassroots drive the research questions, the methods used and the forms of outputs to be delivered. For citizen science, the goal might be summarised to explore and explain the world more broadly and with enhanced ingenuity. For PAR the goal is to use inquiry as a tool to contest unjust power relations.
If public participation in scientific research initiatives are to be applied towards an action research agenda, it must ground its findings in the systems of power, control, jurisdiction and decision making systems that govern how any evidence produced may be received and then acted upon. The key to do this for open agri-environmental research is the expansion and development of land ownership data.
In its simplest form, land ownership data are best understood as a parcel boundary. The data show where property lines exist in space and who is listed as the owner. Even in this basic form, the potential for environmental analysis is drastically expanded. A researcher can understand how many owners there are in a landscape, how consolidated the land is or how fragmented. But parcel data often contains other important information, such as any zoning rules that apply, land valuation, the tax address of the landowners. In many locales around the world, land ownership data is public information—county assessor’s offices in the US, for example, are all mandated to provide these data when queried .
Combining who owns farmland with other environmental data, one can begin to ask higher order questions like “Which farmland owners are contributing to certain patterns in nitrogen runoff, biodiversity conservation and pesticide application? Who are the top twenty farmland owners who control the most habitat for important species diversity? Is the agricultural matrix in my town made up of a network of small family farmers selling domestic products or corporate owners specialising in export production?
Imagine if iNaturalist, an open data and citizen science initiative, also provided land ownership data? Suddenly, the tool becomes not just about where the relative abundances of species are, but who has the power to influence the stability of these distributions. Of course this would implicate the platform in new, messy political contests, but I argue these contests are where transformative science occurs.
Before this potential is realised, progress must be made towards open land ownership data that is both functional and governed democratically. While open land ownership information would revolutionise the ability to practice open inquiry in the agricultural sector, it brings with it some wicked problems and known drawbacks that must be contended with.
Diving into this tenuous balance is the Scottish Government, that by decree of the government's various Land Reform Acts, has mandated the official land registry be completed and made digitally public by 2024. The goal of the Scottish Land Reform Agenda is to rebalance the shape of land tenure, moving the land from large estates to a diversity of ownership forms, especially community ownership. The legislation sets up a new process, funding and legal powers for communities to register their interest in any asset in Scotland, with the goal of protecting local community interest in asset acquisition when it comes up for sale. In some cases (of neglect, vacancy, or unsustainability) a community group can force the sale of an asset from private landowner to the community .
Based on my experience studying how Scotland’s unique land reform policies may change agricultural practices, I sense that the Scottish Government recognises that if it wants communities to be able to identify, study, and put forth productive land use visions they first need to understand who owns the land, its boundaries in space and the surrounding land ownership context. As evident in the government’s Land Rights and Responsibilities Statement, owners of land are thought to have a responsibility to use the balances of private and public goods.
In the most recent part of the Land Reform agenda, the law states that a community group can begin a process of compulsory sale of land if the community can adequately claim that the land in its current use and management impedes the sustainability of the community. Here is where citizen science and open land ownership data converge to produce new outcomes for society. For this land reform objective to work, non-expert community groups must be able to swiftly understand landscape dynamics related to property boundaries, make compelling evidence-based arguments and mobilise action based on the results. This is only achievable with a usable, well governed open and ownership system.
Of course, it remains to be seen if the data provided by the Register of Scotland is usable by a broad array of publics. But importantly, instead of software developers to monetise these datasets, tools could be built to serve the ambitions of citizen scientists and community land reformers. Because of the mandate of the Register of Scotland, tools like Shared Asset’s Land Explorer is an early example of a mission driven land interface that supports the goals of community science.
For Public Participation in Science on agriculture to be transformative and move it more towards participatory action research, you have to know who owns what. Although tenuous, open land ownership data is the way forward. Otherwise, the benefits of land ownership data will only benefit the powerful, hidden from community inquiry.

 Or land rights information
 Different legal rules apply to the provision of these data. Some counties have stricter privacy rules that prevent the disclosure of addresses. These rules are often in delicate balance with a duty to provide the public with tax assessment information. Some counties are just cash strapped and don’t spend on the ongoing maintenance of a complex geospatial database.
