A Review of Citizen Science and Crowdsourcing in Applications of Pluvial Flooding

Curated on Posted on by Stefaan Verhulst

Jonathan D. Paul in Frontiers in Earth Science: “Pluvial flooding can have devastating effects, both in terms of loss of life and damage. Predicting pluvial floods is difficult and many cities do not have a hydrodynamic model or an early warning system in place. Citizen science and crowdsourcing have the potential for contributing to early warning systems and can also provide data for validating flood forecasting models. Although there are increasing applications of citizen science and crowdsourcing in fluvial hydrology, less is known about activities related to pluvial flooding. Hence the aim of this paper is to review current activities in citizen science and crowdsourcing with respect to applications of pluvial flooding.

Based on a search in Scopus, the papers were first filtered for relevant content and then classified into four main themes. The first two themes were divided into (i) applications relevant during a flood event, which includes automated street flooding detection using crowdsourced photographs and sensors, analysis of social media, and online and mobile applications for flood reporting; and (ii) applications related to post-flood events. The use of citizen science and crowdsourcing for model development and validation is the third theme while the development of integrated systems is theme four. All four main areas of research have the potential to contribute to early warning systems and build community resilience. Moreover, developments in one will benefit others, e.g., further developments in flood reporting applications and automated flood detection systems will yield data useful for model validation….(More)”.

Citizen science for environmental policy: Development of an EU-wide inventory and analysis of selected practices

Curated on Posted on by Stefaan Verhulst

EU Science Hub: “Citizen science is the non-professional involvement of volunteers in the scientific process, whether in the data collection phase or in other phases of the research.

It can be a powerful tool for environmental management that has the potential to inform an increasingly complex environmental policy landscape and to meet the growing demands from society for more participatory decision-making.

While there is growing interest from international bodies and national governments in citizen science, the evidence that it can successfully contribute to environmental policy development, implementation, evaluation or compliance remains scant.

Central to elucidating this question is a better understanding of the benefits delivered by citizen science, that is to determine to what extent these benefits can contribute to environmental policy, and to establish whether projects that provide policy support also co-benefit science and encourage meaningful citizen engagement.

EU-wide inventory 

In order to get an evidence base of citizen science activities that can support environmental policies in the European Union (EU), the European Commission (DG ENV, with the support of DG JRC) contracted Bio Innovation Service (FR), in association with Fundacion Ibercivis (ES) and The Natural History Museum (UK), to perform a “Study on an inventory of citizen science activities for environmental policies”.

The first objective was to develop an inventory of citizen science projects relevant for environmental policy and assess how these projects contribute to the Sustainable Development Goals (SDGs) set by the United Nations (UN) General Assembly.

To this end, a desk-research and an EU-wide survey were used to identify 503 citizen science projects of relevance to environmental policy.

The study demonstrates the breadth of citizen science that can be of relevance to environmental policy....Three salient features were found:

  • Government support, not only in the funding, but also through active participation in the design and implementation of the project appears to be a key factor for the successful uptake of citizen science in environmental policy.
  • When there is easy engagement process for the citizens, that is, with projects requiring limited efforts and a priori skills, this facilitates their policy uptake.
  • Scientific aspects on the other hand did not appear to affect the policy uptake of the analysed projects, but they were a strong determinant of how well the project could serve policy: projects with high scientific standards and endorsed by scientists served more phases of the environmental policy cycle.

In conclusion, this study demonstrates that citizen science has the potential to be a cost-effective way to contribute to policy and highlights the importance of fostering a diversity of citizen science activities and their innovativeness….(More)”.

Learning Through Citizen Science: Enhancing Opportunities by Design

Curated on Posted on by Stefaan Verhulst

National Academies: “Scientific research that involves nonscientists contributing to research processes – also known as ‘citizen science’ – supports participants’ learning, engages the public in science, contributes to community scientific literacy, and can serve as a valuable tool to facilitate larger scale research, says a new report from the National Academies of Sciences, Engineering, and Medicine.  If one of the goals of a citizen science project is to advance learning, designers should plan for it by defining intended learning outcomes and using evidence-based strategies to reach those outcomes.

“This report affirms that citizen science projects can help participants learn scientific practices and content, but most likely only if the projects are designed to support learning,” says Rajul Pandya, chair of the committee that wrote the report and director, Thriving Earth Exchange, AGU.  

The term “citizen science” can be applied to a wide variety of projects that invite nonscientists to engage in doing science with the intended goal of advancing scientific knowledge or application. For example, a citizen science project might engage community members in collecting data to monitor the health of a local stream. As another example, among the oldest continuous organized datasets in the United States are records kept by farmers and agricultural organizations that document the timing of important events, such as sowing, harvests, and pest outbreaks.

Citizen science can support science learning in several ways, the report says. It offers people the opportunity to participate in authentic scientific endeavors, encourages learning through projects conducted in real-world contexts, supports rich social interaction that deepens learning, and engages participants with real data. Citizen science also includes projects that grow out of a community’s desire to address an inequity or advance a priority. For example, the West-Oakland Indicators Project, a community group in Oakland, Calif., self-organizes to collect and analyze air quality data and uses that data to address trucking in and around schools to reduce local children’s exposure to air pollution. When communities can work alongside scientists to advance their priorities, enhanced community science literacy is one possible outcome….

In order to maximize learning outcomes, the report recommends that designers and practitioners of citizen science projects should intentionally build them for learning. This involves knowing the audience; intentionally designing for diversity; engaging stakeholders in the design; supporting multiple kinds of participant engagement; encouraging social interaction; building learning supports into the project; and iteratively improving projects through evaluation and refinement.  Engaging stakeholders and participants in design and implementation results in more learning for all participants, which can support other project goals. 

The report also lays out a research agenda that can help to build the field of citizen science by filling gaps in the current understanding of how citizen science can support science learning and enhance science education. Researchers should consider three important factors: citizen science extends beyond academia and therefore, evidence for practices that advance learning can be found outside of peer-reviewed literature; research should include attention to practice and link theory to application; and attention must be given to diversity in all research, including ensuring broad participation in the design and implementation of the research. Pursuing new lines of inquiry can help add value to the existing research, make future research more productive, and provide support for effective project implementation….(More)”.


Citizen science, public policy

Curated on Posted on by Stefaan Verhulst

Paper by Christi J. Guerrini, Mary A. Majumder,  Meaganne J. Lewellyn, and Amy L. McGuire in Science: “Citizen science initiatives that support collaborations between researchers and the public are flourishing. As a result of this enhanced role of the public, citizen science demonstrates more diversity and flexibility than traditional science and can encompass efforts that have no institutional affiliation, are funded entirely by participants, or continuously or suddenly change their scientific aims.

But these structural differences have regulatory implications that could undermine the integrity, safety, or participatory goals of particular citizen science projects. Thus far, citizen science appears to be addressing regulatory gaps and mismatches through voluntary actions of thoughtful and well-intentioned practitioners.

But as citizen science continues to surge in popularity and increasingly engage divergent interests, vulnerable populations, and sensitive data, it is important to consider the long-term effectiveness of these private actions and whether public policies should be adjusted to complement or improve on them. Here, we focus on three policy domains that are relevant to most citizen science projects: intellectual property (IP), scientific integrity, and participant protections….(More)”.

Information to Action: Strengthening EPA Citizen Science Partnerships for Environmental Protection

Curated on Posted on by admin

Report by the National Advisory Council for Environmental Policy and Technology: “Citizen science is catalyzing collaboration; new data and information brought about by greater public participation in environmental research are helping to drive a new era of environmental protection. As the body of citizen-generated data and information in the public realm continues to grow, EPA must develop a clear strategy to lead change and encourage action beyond the collection of data. EPA should recognize the variety of opportunities that it has to act as a conduit between the public and key partners, including state, territorial, tribal and local governments; nongovernmental organizations; and leading technology groups in the private sector. The Agency should build collaborations with new partners, identify opportunities to integrate equity into all relationships, and ensure that grassroots and community-based organizations are well supported and fairly resourced in funding strategies.

Key recommendations under this theme:

  • Recommendation 1. Catalyze action from citizen science data and information by providing guidance and leveraging collaboration.
  • Recommendation 2. Build inclusive and equitable partnerships by understanding partners’ diverse concerns and needs, including prioritizing better support for grassroots and community-based partnerships in EPA grantfunding strategies.

Increase state, territorial, tribal and local government engagement with citizen science

The Agency should reach out to tribes, states, territories and local governments throughout the country to understand the best practices and strategies for encouraging and incorporating citizen science in environmental protection. For states and territories looking for ways to engage in citizen science, EPA can help design strategies that recognize the community perspectives while building capacity in state and territorial governments. Recognizing the direct Executive Summary Information to Action: Strengthening EPA Citizen Science Partnerships for Environmental Protection connection between EPA and tribes, the Agency should seek tribal input and support tribes in using citizen science for environmental priorities. EPA should help to increase awareness for citizen science and where jurisdictional efforts already exist, assist in making citizen science accessible through local government agencies. EPA should more proactively listen to the voices of local stakeholders and encourage partners to embrace a vision for citizen science to accelerate the achievement of environmental goals. As part of this approach, EPA should find ways to define and communicate the Agency’s role as a resource in helping communities achieve environmental outcomes.

Key recommendations under this theme:

  • Recommendation 3. Provide EPA support and engage states and territories to better integrate citizen science into program goals.
  • Recommendation 4. Build on the unique strengths of EPA-tribal relationships.
  • Recommendation 5. Align EPA citizen science work to the priorities of local governments.

Leverage external organizations for expertise and project level support

Collaborations between communities and other external organizations—including educational institutions, civic organizations, and community-based organizations— are accelerating the growth of citizen science. Because EPA’s direct connection with members of the public often is limited, the Agency could benefit significantly by consulting with key external organizations to leverage citizen science efforts to provide the greatest benefit for the protection of human health and the environment. EPA should look to external organizations as vital connections to communities engaged in collaboratively led scientific investigation to address community-defined questions, referred to as community citizen science. External organizations can help EPA in assessing gaps in community-driven research and help the Agency to design effective support tools and best management practices for facilitating effective environmental citizen science programs….(More)”.

Help NASA create the world’s largest landslide database

Curated on Posted on by Stefaan Verhulst

EarthSky: “Landslides cause thousands of deaths and billions of dollars in property damage each year. Surprisingly, very few centralized global landslide databases exist, especially those that are publicly available.

Now NASA scientists are working to fill the gap—and they want your help collecting information. In March 2018, NASA scientist Dalia Kirschbaum and several colleagues launched a citizen science project that will make it possible to report landslides you have witnessed, heard about in the news, or found on an online database. All you need to do is log into the Landslide Reporter portal and report the time, location, and date of the landslide – as well as your source of information. You are also encouraged to submit additional details, such as the size of the landslide and what triggered it. And if you have photos, you can upload them.

Kirschbaum’s team will review each entry and submit credible reports to the Cooperative Open Online Landslide Repository (COOLR) — which they hope will eventually be the largest global online landslide catalog available.

Landslide Reporter is designed to improve the quantity and quality of data in COOLR. Currently, COOLR contains NASA’s Global Landslide Catalog, which includes more than 11,000 reports on landslides, debris flows, and rock avalanches. Since the current catalog is based mainly on information from English-language news reports and journalists tend to cover only large and deadly landslides in densely populated areas, many landslides never make it into the database….(More)”.

From Crowdsourcing to Extreme Citizen Science: Participatory Research for Environmental Health

Curated on Posted on by Stefaan Verhulst

P.B. English, M.J. Richardson, and C. Garzón-Galvis in the Annual Review of Public Health: “Environmental health issues are becoming more challenging, and addressing them requires new approaches to research design and decision-making processes. Participatory research approaches, in which researchers and communities are involved in all aspects of a research study, can improve study outcomes and foster greater data accessibility and utility as well as increase public transparency. Here we review varied concepts of participatory research, describe how it complements and overlaps with community engagement and environmental justice, examine its intersection with emerging environmental sensor technologies, and discuss the strengths and limitations of participatory research. Although participatory research includes methodological challenges, such as biases in data collection and data quality, it has been found to increase the relevance of research questions, result in better knowledge production, and impact health policies. Improved research partnerships among government agencies, academia, and communities can increase scientific rigor, build community capacity, and produce sustainable outcomes….(More)”

Coastal research increasingly depends on citizen scientists

Curated on Posted on by Stefaan Verhulst

Brenna Visser at CS Monitor: “…This monthly ritual is a part of the COASST survey, a program that relies on data taken by volunteers to study large-scale patterns in seabird populations on the West Coast. The Haystack Rock Awareness Program conducts similar surveys for sea stars and marine debris throughout the year.

Surveys like these play a small part in a growing trend in the science community to use citizen scientists as a way to gather massive amounts of data. Over the weekend, marine scientists and conservationists came to Cannon Beach for an annual Coast Conference, a region wide event to discuss coastal science and stewardship.

Whether the presentation was about ocean debris, marine mammals, seabirds, or ocean jellies, many relied on the data collection work of volunteers throughout the state. A database for citizen science programs called Citsci.org, which recorded only a few dozen groups 10 years ago, now has more than 500 groups registered across the country, with new ones registering every day….

Part of the rise has to do with technology, she said. Apps that help identify species and allow unprecedented access to information have driven interest up and removed barriers that would have otherwise made it harder to collect data without formal training. Another is the science community slowly coming around to accept citizen science.

“I think there’s a lot of reticence in the science community to use citizen science. There’s some doubt the data collected is of the precision or accuracy that is needed to document phenomena,” Parrish said. “But as it grows, the more standardized it becomes. What we’re seeing right now is a lot of discussion in citizen science programs asking what they need to do to get to that level.”…While a general decline in federal funding for scientific research could play a factor in the science community’s acceptance of using volunteer-collected data, Parrish said, regardless of funding, there are some projects only citizen scientists can accomplish….(More)”

The Promise of Community Citizen Science

Curated on Posted on by Stefaan Verhulst

Report by Ramya Chari, Luke J. Matthews, Marjory S. Blumenthal, Amanda F. Edelman, and Therese Jones: “Citizen science is public participation in research and scientific endeavors. Citizens volunteer as data collectors in science projects; collaborate with scientific experts on research design; and actively lead and carry out research, exerting a high degree of control and ownership over scientific activities. The last type — what we refer to as community citizen science — tends to involve action-oriented research to support interventional activities or policy change. This type of citizen science can be of particular importance to those working at the nexus of science and decisionmaking.

The authors examine the transformative potential of community citizen science for communities, science, and decisionmaking. The Perspective is based on the authors’ experiences working in collaboration with community groups, extensive readings of the scientific literature, and numerous interviews with leading scholars and practitioners in the fields of citizen science and participatory research. It first discusses models of citizen science in general, including community citizen science, and presents a brief history of its rise. It then looks at possible factors motivating the development of community citizen science, drawing from an exploration of the relationships among citizens, science, and decisionmaking. The final section examines areas in which community citizen science may exhibit promise in terms of outcomes and impacts, discusses concerns that may hinder its overall potential, and assesses the roles different stakeholders may play to continue to develop community citizen science into a positive force for science and society.

Key Findings

At Its Core, Citizen Science Is Public Participation in Research and Scientific Endeavors

  • Citizens volunteer as data collectors in science projects, collaborate with scientific experts on research design, and actively lead and carry out research.
  • It is part of a long tradition of rebirth of inventors, scientists, do-it-yourselfers, and makers at all levels of expertise.
  • Instead of working alone, today’s community citizen scientists take advantage of new technologies for networking and coordination to work collaboratively; learn from each other; and share knowledge, insights, and findings.

The Democratization of Science and the Increasingly Distributed Nature of Expertise Are Not Without Concern

  • There is some tension and conflict between current standards of practice and the changes required for citizen science to achieve its promising future.
  • There is also some concern about the potential for bias, given that some efforts begin as a form of activism.

Yet the Efforts of Community Citizen Science Can Be Transformative

  • Success will require an engaged citizenry, promote more open and democratic decisionmaking processes, and generate new solutions for intractable problems.
  • If its promise holds true, the relationship between science and society will be profoundly transformed for the betterment of all…(More)”.
