Open government data and environmental science: a federal Canadian perspective

Governments worldwide are releasing data into the public domain via open government data initiatives. Many such data sets are directly relevant to environmental science and complement data collected by academic researchers to address complex and challenging environmental problems. The Government of Canada is a leader in open data among Organisation for Economic Co-operation and Development countries, generating and releasing troves of valuable research data. However, achieving comprehensive and FAIR (findable, accessible, interoperable, reusable) open government data is not without its challenges. For example, identifying and understanding Canada’s international commitments, policies, and guidelines on open data can be daunting. Similarly, open data sets within the Government of Canada are spread across a diversity of repositories and portals, which may hinder their discoverability. We describe Canada’s federal initiatives promoting open government data, and outline where data sets of relevance to environmental science can be found. We summarize research data management challenges identified by the Government of Canada, plans to modernize the approach to open data for environmental science and best practices for data discoverability, access, and reuse.


Introduction
Environmental science increasingly relies on combining disparate data from multiple sources to answer questions involving, for example, broad geographical areas, multiple time periods, many species, and complex systems or issues (Barone et al. 2017;Cheruvelil and Soranno 2018;Poisot et al. 2019). The resulting data sets (sometimes leading to Big Data) may generate deeper and more robust insights than spatially and temporally restricted data, and have the potential to better inform environmental management and conservation policy (Huang and Qiao 2011;McClenachan et al. 2012;Wolkovich et al. 2012). Concurrent with the technological advances in data sharing (Hipsley and Sherratt 2019), there is a growing sentiment among scientists and governments that open and FAIR (findable, accessible, interoperable, reusable) data (Appendix 1) increase the speed, scope, quality, and value of scientific research (Molloy 2011;Borgman 2012). Key benefits of open research data include: preserving information to ensure the continuity of scientific discovery, allowing the verification of research results by improving transparency and reproducibility, maximizing returns on public investments in research, enabling data synthesis and reuse to advance research and innovation, and facilitating education and public outreach and participation (Roche et al. 2014). Consequently, a growing number of funders and publishers are adopting policies that require scientists to share their data and computer code on public platforms upon publishing their results (Roche 2016;Nature Editorial 2018;Renaut et al. 2018). These policies are gaining traction across the natural and social sciences, resulting in greater data deposition rates by academics into publicly accessible repositories (Vines et al. 2013; Science Digital 2019).
Such policies have strong potential to incentivize data sharing by academic researchers. However, governments also conduct research and amass rich environmental data sets and in some cases are less beholden to funding agencies. For example, over 1.1 million scientists and engineers work for the United States government (National Science Foundation 2015). In Canada, the federal government employs approximately 25 000 scientists in natural sciences and engineering alone (Statistics Canada 2012). Several science-based departments and agencies (SBDAs) within the Canadian government generate data of direct relevance to environmental management and biodiversity conservation, often through long-term research and monitoring programs ( Table 1). Between 2012 and 2015, federal SBDAs published 17 695 scientific journal articles, representing 6.8% of all peer-reviewed publications by Canadian scientists (Open Science Metrics Working Group 2018). Canada is also fourth among Organisation for Economic Co-operation and Development (OECD) countries in terms of the spending on government research as a fraction of gross domestic product (OECD 2019b).
Government employees, as is the case for academic researchers, must share the data necessary to reproduce their results when publishing in journals requiring open data. However, government employees also regularly publish using a diversity of other media, including reports, specialized publications, and government periodicals that are not subject to academic publishers' open data policies. Many federal SBDAs (e.g., Statistics Canada, the Department of Fisheries and Oceans, and Environment and Climate Change Canada) have been publicly releasing comprehensive data sets for decades (Environment and Climate Change Canada 2019). However, all departments and agencies must now participate in open data in line with Canada's commitments to international agreements and important changes in government policy and directives ( In general, recent progress on open data in the academic and government sectors is encouraging. However, the implementation of new open data policies poses important technical and cultural challenges that have yet to be resolved, both in government and in academic institutions. For example, data management practices vary considerably among disciplines, institutions, and research groups, slowing the adoption of data sharing standards and best practices (Hipsley and Sherratt 2019;Poisot et al. 2019). As a result, researchers often struggle to share their data in formats that are readily understandable and reusable by third parties (Poisot et al. 2019). For example, a 2015 study found that over 50% of open data sets shared by ecologists and evolutionary biologists were unusable (Roche et al. 2015). Additionally, the ever-increasing volume and complexity of data sets in environmental science requires that institutions allocate considerable resources to help scientists curate, store, and share their data effectively. Presently, most research data are shared in a decentralized fashion, across a diversity of repositories and portals (Open Science Metrics Working Group 2018; Privy Council Office Government of Canada 2018), creating challenges for their discovery, integration, and reuse. In addition, restricted data (e.g., personally identifiable information, confidential business information, intellectual property) and sensitive data (e.g., the location of commercially valuable species or species at risk) (e.g., Lennox et al. 2020) require an additional layer of data management to balance access and security.
Along with 34 other OECD countries, Canada has established formal requirements for publicly sharing government data. In 2019, Canada ranked third among OECD members on the basis of  Recognizing these challenges, the Government of Canada is intent on achieving more efficient and cohesive data governance. Here, we synthesize the current status of open research data (Appendix 1) produced by the Government of Canada, focusing on environmental sciences (broadly defined-including natural, social, and physical science perspectives given the inherent interdisciplinary nature of environmental science (Dick et al. 2016)).
This paper targets diverse parties with a stake in open environmental data, including Government of Canada researchers, information technology officers, policy analysts, and executives, as well as academic researchers outside of government. Our aim is to outline: (i) the landscape of federal initiatives that promote open data in environmental science, (ii) indicate how and where these data are shared (including existing infrastructure and best practices), and (iii) discuss planned improvements to open data practices in the Government of Canada.

The Government of Canada's commitments, policies, and directives on open data
In recent years, the Government of Canada has pledged to increase public accessibility of its data by signing international agreements and promulgating policies and directives to this end via its executive and legislative branches (Fig. 1). These policies and directives apply to both administrative agencies and SBDAs. We identified nine SBDAs within the Government of Canada that produce research data relevant to environmental science ( Table 1).

International commitments
In 2011, Canada adopted the International Open Data Charter (opendatacharter.net) and launched its first Action Plan on Open Government in 2012. Four action plans have now been tabled in the context of the Open Government Partnership (OGP; opengovpartnership.org), an international initiative to improve transparency, public participation, and accountability in governance. Canada joined the OGP in 2011 and co-chaired the organization in 2018 and 2019. National Action Plans on Open Government are tabled biennially and formulate commitments to be implemented over a two-year period. For example, in its third biennial plan to the OGP (2016-2017), Canada formulated 22 commitments to promote transparency in government, including increasing the openness of federal science activities (Commitment 13) and aligning the implementation of open data across Canada (Commitment 14) (Government of Canada 2016). Governments must report on the implementation of their action plan to the OGP via a self-assessment report and OGP's independent review process (Government of Canada 2018).
In 2013, the Government of Canada adopted the G8 Open Data Charter (G8 Leaders 2013), stipulating that all government data should be published openly by default and outlining core principles to increase the quality, quantity, and reuse potential of open data. The government then formally endorsed a set of data principles in 2016 via the G20 Hangzou Concensus (G20 Leaders 2016), a communiqué in which the G20 leaders support efforts to "promote open science and facilitate appropriate access to publicly funded research results based on Findable, Accessible, Interoperable and Reusable (FAIR) data principles" (Wilkinson et al. 2016).
Canada is also a member of the G7 Expert Group on Open Science tasked with making recommendations on incentives and infrastructure to increase the speed and coherence of national transitions towards open science (G7 Science and Technology Ministers 2016). In 2017, the working group Roche et al.
FACETS | 2020 | 5: 942-962 | DOI: 10.1139/facets-2020-0008 946 facetsjournal.com recommended that G7 nations promote research data management practices that adhere to FAIR data principles and develop infrastructure allowing researchers to deposit, access, and analyze data across disciplines on a global scale (G7 Open Science Working Group 2017).
Finally, international commitments specific to the environment demonstrate Canada's recognition of the importance of open data. For example, Canada's commitments under the Convention on Biological Diversity are articulated at a national level in the "2020 Biodiversity Goals and Targets for Canada". Target 14 specifically addresses the need for a "science base [that is] better integrated and more accessible", with indicators of performance under this target specifically related to the amount of environmental data being contributed to online repositories and portals (Biodivcanada 2015).

Policies and directives
Policies are developed by the Treasury Board of Canada Secretariat (TBS) to provide direction to departments and agencies on how to orient their activities toward the achievement of results, enact good stewardship of public resources, and assist ministers in their accountability to Parliament (Treasury Board of Canada Secretariat 2008). Policies provide formal directions that impose specific responsibilities on departments and expectations for heads of departments and agencies and their officials. Directives detail how policy objectives must be met by providing formal instruction obliging departments to take or avoid specific action. Several policies and directives formulate specific requirements regarding transparency and data sharing within the Government of Canada. An in-depth analysis of the hierarchy of policy instruments demonstrated that the guidelines and authorities that support open science can be traced back to the values and ethics code for the public service (Austin 2020). All TBS policies and directives are mandatory across federal departments and agencies.

The Policy on Service and Digital
This policy came into effect on 1 April 2020 (Treasury Board of Canada Secretariat 2020) and replaced several existing policies such as the Policy on Information Management and the Policy Framework for Information and Technology (Fig. 1). This new policy provides an integrated set of rules for how Government of Canada organizations and employees must manage data, information, and cyber security, among other things. Key aspects of the policy relating to research data management include official languages, privacy, and accessibility requirements, as well as commitments to Government of Canada Digital Standards such as good data stewardship, working in the open by default, using open standards and tools, and addressing data security and privacy risks.

Scientific integrity policies
On 30 July 2018, The Office of the Chief Science Advisor released a Model Policy on Scientific Integrity (Office of the Chief Science Advisor 2018). This model serves as a framework for the adoption of scientific integrity policies by 21 SBDAs to proactively strengthen the reliability and credibility of research and scientific activities undertaken by the federal government (Table S1) (Treasury Board of Canada Secretariat 2018d). A core principle of the Model Policy is that research data and information be made openly accessible in a timely and transparent manner unless there are clear and compelling reasons preventing full disclosure.

Data Strategy Roadmap
Co-authored by Statistics Canada, the Treasury Board Secretariat, and the Office of the Privy Council in 2018 (Privy Council Office Government of Canada 2018), this document outlines the current state of data management practices within the federal government, ongoing challenges, and a comprehensive set of 21 recommendations to improve how the government manages, uses, and shares data both internally and externally.

Roadmap for Open Science
This document (Office of the Chief Science Advisor 2020) provides overarching principles and recommendations to guide Open Science activities in Canada, in particular for science and research funded by federal government departments and agencies.

Implementation of open environmental data by federal science-based departments and agencies
Government scientists and SBDAs seeking to make environmental data publicly available have a range of options of where and how to share them (Culina et al. 2018; Open Science Metrics Working Group 2018). Data repositories are servers that host data, whereas data portals and registries (Appendix 1) contain links and information about data sets stored elsewhere. Portals and repositories are searchable via their own search engines. Additionally, general and discipline-specific repositories can be searched via data aggregators (e.g., DataOne, DataCite, Google Dataset Search) (Culina et al. 2018;Canino 2019). For example, data sets on Canada's Open Government Portal (see below) are discoverable via Google Dataset Search, resulting in approximately 5% of the overall traffic to data set pages on the portal (Treasury Board of Canada Secretariat, personal communication, 2019).
Selecting a suitable data repository is key for ensuring data preservation and discoverability. Similarly, the way in which data are shared (i.e., format, resolution, and metadata) greatly influences their reuse potential. The government's recent commitments and policies towards greater transparency have led to improvements in digital infrastructure and guidelines for sharing research data. Some of these improvements, and the remaining challenges, are described below.

Infrastructure
The Government of Canada currently maintains dozens of SBDA-led data repositories and portals, which can be readily browsed and (or) searched by potential reusers seeking discipline-or agencyspecific data sets (Table S2). All SBDAs producing data of relevance to environmental science release data for public consumption, except for the Impact Assessment Agency of Canada (IAAC). Environment and Climate Change Canada, for example, hosts over 40 different data portals providing access to data sets such as species occurrences, climate data, and data on air and water quality (Environment and Climate Change Canada 2019). Fisheries and Oceans Canada shares data on aquaculture, fisheries, and import and export of fisheries products, most of which date back to the 1980s and 1990s. IAAC makes records of environmental assessments available upon request, but does not own or curate data collected by third parties responsible for project assessments. However, the 2019

Roche et al.
FACETS | 2020 | 5: 942-962 | DOI: 10.1139/facets-2020-0008 948 facetsjournal.com Impact Assessment Act will facilitate public release of documents and data through the IAAC's online public registry and the Government of Canada's proposed new Cumulative Effects Open Science and Data Platform (Government of Canada 2019). This platform is intended to provide public access to information and data that support decision-making on major projects such as pipelines and mines.
The Government of Canada launched the Open Government Portal (open.canada.ca) in March 2011 (previously named the Open Data Portal) to centralize cataloguing of federal data collected by different SBDAs. The Portal acts as a federated registry of government open data sets, supporting national policies and meeting international commitments to foster open data. A federated registry is a system that integrates several independent repositories or platforms in a single user interface: when the registry is queried, the system finds which of its component repositories or platforms contains the requested data and passes the request to it. Canada's Federated Research Data Repository is an example of a federated system outside the Government of Canada (frdr.ca). At the time of writing, the Open Government Portal was supported by a team of 5-6 technical staff in the Treasury Board Secretariat: it can host data sets and link to data sets archived elsewhere, but it is not intended to replace existing repositories. Rather, it is meant to consolidate open data metadata from across government into a readily searchable, centralized catalogue or registry that links to data found on federal or external platforms. The Open Government Portal consists of three components: (i) financial, human resources and government operations information (the Proactive Disclosure Portal), (ii) publications and digital information resources (the Open Information Portal), and (iii) data sets (the Open Data Portal). As of May 2019, 79 824 federal data sets were listed on the Open Data Portal, nearly all of them (98.3%) contributed by SBDAs producing data of relevance to environmental science ( Table 1)

Best practices in research data management and sharing
General guidelines and best practices in data stewardship (Fig. 2) are applicable across domains, to government and nongovernment scientists alike. Open data should comply with the FAIR data principles (Wilkinson et al. 2016), which are described on the GO-FAIR website (go-fair.org/). Briefly, data are findable and accessible when they are archived and freely available from an indexed and searchable public data repository. Data are interoperable and reusable when humans and computers can readily understand them (e.g., via metadata) and explore and reuse them using a range of nonproprietary software. Interoperability and reusability hinge largely on the ease of use of data and file formats (White et al. 2013;Hart et al. 2016), a metadata language (Wilkinson et al. 2018), and a usage license (e.g., creativecommons.org/licenses). Metrics have recently been developed to assess compliance with the FAIR data principles (Wilkinson et al. 2018).
Scientists do not necessarily have a background or training in research data management (Popkin 2019). However, best practice guidelines (Box 1) and open education resources are a good source of free training in research data management (Box 2). Good data stewardship begins with a Data Management Plan (DMP) outlining essential aspects of research data management a priori (Austin Michener 2015). Key elements include determining adequate file formats, data formats, documentation needed to describe the data (i.e., metadata), storage and backup locations, and compliance with ethical considerations in the case of research on humans and other vertebrates (step 1 in Fig. 2) (White et al. 2013). The online Portage Network DMP Assistant (assistant.portagenetwork.ca; see Box 1) and the DMP Common Standard (RDA 2020) may be useful resources.
Once data collection begins, data must be stored and backed-up safely (step 2 in Fig. 2). Adequate formats must be used and metadata provided allowing the data generator(s) and third parties to easily interpret and explore and reuse the data (step 3 in Fig. 2; Box 1). Next, data quality and standardization must be checked to identify erroneous entries and comply with any government-or disciplinespecific standards (steps 4 and 5 in Fig. 2). Resources such as Statistics Canada's Data Quality Toolkit (statcan.gc.ca/eng/data-quality-toolkit) are broadly applicable to assist with this step. In government, researchers can consult with their respective SBDA's information management team or data management officer(s) for assistance.
Adequate data protection measures must then be implemented if necessary, and a suitable public data repository identified (step 6, in Fig. 2; Box 3) (Culina et al. 2018). Sensitive data might include personal identifiers and the location of valuable infrastructure or species, which might pose a security, privacy, or conservation risk if disclosed publicly (Lindenmayer and Scheele 2017). Various means of protecting data exist to allow their release and align with international commitments (e.g., by the G7, G8, and G20) to make government data "as open as possible and as closed as necessary".

Roche et al.
FACETS | 2020 | 5: 942-962 | DOI: 10.1139/facets-2020-0008 953 facetsjournal.com measures include anonymizing data (i.e., removing identifiers such as participants' names), reducing spatial resolution (for geospatial data), applying an embargo on data release (i.e., archiving data but delaying their public release), and implementing access control (i.e., vetting the credentials of potential data reusers) (Box 1). Once these considerations are addressed, and a publishing license has been chosen (Dodds 2013), a public identifier (e.g., a digital object identifier-DOI) is assigned to the data, which can then be shared publicly (step 7 in Fig. 2).

Modernization of research data management and open data within the Government of Canada
The Open Government Directive holds the promise of making vast amounts of untapped government research data accessible to environmental scientists and other interested parties. However, achieving this directive's full potential presents various challenges, in part because the volume of data collected by SBDAs is growing exponentially, in concert with advances in digital technologies (Privy Council Office Government of Canada 2018). In its 2018 Data Strategy Roadmap, the Government of Canada recognizes these challenges and the need to act rapidly to meet its international commitments (Privy Council Office Government of Canada 2018); the authors of the report noted: Data are often collected in ways-based on informal principles and practices-that make it difficult to share with other departments or Canadians. Their use is inconsistent across the government and their value sub-optimized in the decision-making process and in day-today operations. [ : : : ] Managing, using and sharing data will be crucial in the coming years, but the government is not set up to treat data as a strategic asset for policymaking, program design or service delivery, or to create value for the public, private, not-for-profit, and research sectors. Across the government, data are created, used and stored within individual areas and are often limited to use for a single purpose. Access, use and re-use between and within organizations are often difficult, in part because of a lack of awareness that data could be useful to others and a reticence to share information with others. [ : : : ] While intragovernmental data sharing does occur, it is often via ad hoc technical solutions requiring formal letters of agreement signed at the deputy minister level, adding to administrative burden. [ : : : ] Compounding these challenges is the absence of a governance structure or senior-level decision-making table charged with providing strategic direction on data issues and driving cultural change (p. 4).
Specifically, the Data Strategy Roadmap identifies four overarching challenges across government: the absence of horizontal governance for strategic direction on data issues; a lack of data literacy and cultural resilience to break silos; a lack of adequate digital infrastructure and complex rules framework; and difficulties associated with acquiring, governing, and managing large volumes of disparate data (Privy Council Office Government of Canada 2018). These issues are echoed in several individual SBDAs' Open Government Implementation Plans (Table S3), creating inefficiencies within departmental operations. They also compound more general impediments to data sharing, including researchers' fear of being "scooped", concerns about potential errors in their data and analyses being exposed, and the considerable additional time that would be needed to appropriately manage data and metadata.
To remedy these problems, the Data Strategy Roadmap (Privy Council Office Government of Canada 2018) outlines 21 recommendations aimed at modernizing and improving how SBDAs create, manage, protect, use, and share data. These recommendations center around four themes: (i) stronger governance to ensure that data are managed holistically as a strategic asset, (ii) capacity-building to improve data literacy and skills, (iii) enabling infrastructure and legislation to facilitate data Roche et al.
FACETS | 2020 | 5: 942-962 | DOI: 10.1139/facets-2020-0008 954 facetsjournal.com management and analytics, and (iv) a more focused treatment of data as valuable assets such that they are discoverable and available to maximize their social and economic value. Some recommendations are in the process of being implemented-for example, in September 2019, individual SBDAs were asked to submit their own customized data strategies aligning with the standards and principles in the Data Strategy Roadmap. Forty such strategies had been submitted by January 2020 (Statistics Canada, personal communication, 2020). Other concrete recommendations are expected to be rolled out in the coming years. Two key recommendations of the Data Strategy Roadmap are the launch of a digital academy to develop digital and data skills of existing employees and the appointment of a Government of Canada Chief Data Steward to help coordinate decisions on data management issues spanning the whole of government.

Conclusion
The nature of the activities undertaken by government implies that departments and agencies collect, store, manage, and publish considerable amounts of data, including research data (Altayar 2018). By publicly sharing these data, governments contribute to advancing democracy and development through promoting transparency, accountability, and public participation as well as by supporting research and innovation (Zeleti et al. 2016;Ruijer and Martinius 2017). In a 2019 study, 156 open government data initiatives were identified across 61 countries, illustrating rapid progress on this front at a global scale. Key to the success of these initiatives is the implementation of a national data portal enabling users to readily search for and access data sets (OECD 2019a). Portals setup by international governing bodies (e.g., United Nations, European Union, World Bank) and other national governments (Table S4) The ability of environmental scientists to access and synthesize large amounts of data impacts their capacity to understand the natural world and contribute to solving some of the "grand challenges" of the 21st century ( (Reid et al. 2010); grandchallenges.org) and addressing the Sustainable Development Goals ( (Reid et al. 2017); sustainabledevelopment.un.org). Much of the environmental data collected in Canada originate from the federal government through longstanding monitoring efforts; internal research programs; and collaborations with industry, academia, and citizen scientists. At present, research data management and sharing occurs in a fragmented fashion within the federal government. However, bold commitments and initiatives are underway to modernize data governance and stewardship across the whole of government. Importantly, policies and directives mandate that research data, including many environmental data sets, become "open by default" (Privy Council Office Government of Canada 2018). Achieving this objective requires a multi-pronged approachon one hand, changes in data governance and culture will help overcome legacy practices that hinder data sharing, on the other hand, massive investments in digital infrastructure and capacity building will be needed to manage and share data in compliance with internationally recognized standards and best practices. Ultimately, environmental science will benefit from a modern, digital, and dataenabled government that is open to sharing.
