The benefits and negative impacts of citizen science applications to water as experienced by participants and communities

Wiley Interdisciplinary Reviews Water, Journal Year: 2020, Volume and Issue: 8(1)

Abstract Citizen science is proliferating in the water sciences with increasing public involvement monitoring resources, climate variables, quality, and mapping modeling exercises. In addition to well‐reported scientific benefits of such projects, particular solving data scarcity issues, it common extol for participants, example, increased knowledge empowerment. We reviewed 549 publications concerning citizen applications examine personal motivations, wider community benefits. The potential were often simply listed without explanation or investigation. Studies that investigated whether not participants communities actually benefitted from involvement, experienced negative impacts, uncommon, especially Global South. Assuming certain will be can fallacious as some cases intended either achieved fact had impacts. Identified are described we reveal more consideration should given how these interrelate they build capitals foster their realization projects. Additionally, describe identified impacts showing seldom considered though may uncommon borne mind when implementing science. Given time effort commitment made by scientists benefit research, there a need further study involved water, particularly low‐income regions, ensure both researchers benefitting.

Low-cost monitoring systems for urban water management: Lessons from the field

Water Research X, Journal Year: 2024, Volume and Issue: 22, P. 100212 - 100212

Published: Jan. 1, 2024

Sound urban water management relies on extensive and reliable monitoring of infrastructure. As low-cost sensors networks have become increasingly available for environmental monitoring, researchers practitioners must consider the benefits disadvantages such technologies. In this perspective paper, we highlight six technical socio-technological considerations technology to reach its full potential in field management, including: barriers implementation, complementarity with traditional sensing technologies, sensor reliability, added value produced information, opportunities democratize data collection, economic costs technology. For each consideration, present recent experiences from our own work broader literature identify future research needs address current challenges. Our experience supports strong technology, particular that it promotes innovative Future efforts should focus more systematic documenting lower designing, implementing, testing networks, assessing economic, social, deployments.

Citizen science in hydrological monitoring and ecosystem services management: State of the art and future prospects

The Science of The Total Environment, Journal Year: 2019, Volume and Issue: 693, P. 133531 - 133531

Published: July 22, 2019

Hydrological monitoring is essential to guide evidence-based decision making necessary for sustainable water resource management and governance. Limited hydrometric datasets the pressure on long-term hydrological networks make it paramount explore alternative methods data collection. This particularly case low-income countries, where scarcity more pronounced, conventional are expensive logistically challenging. Citizen science in research has recently gained popularity crowdsourced a promising cost-effective approach also potential enhance knowledge co-creation science-based evidence that underpins governance of resources. paper provides comprehensive review citizen collection within context hydrology, based synthesis 71 articles from 2001 2018. Application hydrology increasing number breadth, generating plethora scientific data. approaches differ scale, scope degree involvement. Most programs found North America Europe.

Characterization of wood‐laden flows in rivers

Abstract Inorganic sediment is not the only solid‐fraction component of river flows; flows may also carry significant amounts large organic material (i.e. wood), but characteristics these wood‐laden (WLFs) are well understood yet. With aim to shed light on relatively unexamined phenomena, we collected home videos showing natural with wood as main solid component. Analyses watersheds and streams where were recorded allowed us define for first time WLFs, describe broaden definition transport regimes (adding a new regime called here hypercongested transport). According our results, WLFs occur repeatedly, in range catchment sizes, generally steep, highly confined single thread channels mountain areas. typically unsteady log motion non‐uniform, described other inorganic sediment‐laden (e.g. debris flows).

The use of low-cost sensor networks (LCSNs) is becoming increasingly popular in the environmental sciences and unprecedented monitoring data generated enable research across a wide spectrum disciplines applications. However, particular, non-technical challenges still hinder broader development application LCSNs. This paper reviews LCSNs over last 15 years, highlighting trends future opportunities for diverse range We found air quality, meteorological water-related were particularly well represented with few studies focusing on ecological systems. Furthermore, we identified bias towards that have direct links to human health, safety livelihoods. These more likely involve downstream analytics, visualisations, multi-stakeholder participation through citizen science initiatives. there was paucity considered sustainability factors implementation Existing are largely focussed detecting mitigating events which impact humans such as flooding, pollution or geo-hazards, while these applications important need ecosystem structure function. Our findings highlight three distinct unleash full potential LCSNs: (1) improvement between collection activities; (2) broaden scope systems fields; (3) better integrate stakeholder engagement sustainable operation longer greater societal impacts.

Robust inventories are vital for improving assessment of and response to deadly costly landslide hazards. However, collecting events in is difficult at the global scale due inconsistencies or absence reporting. Citizen science a valuable opportunity addressing some these challenges. The new Cooperative Open Online Landslide Repository (COOLR) supplements data NASA-developed Global Catalog (GLC) with citizen reports build more robust, publicly available inventory. This manuscript introduces COOLR project its methods, evaluates initial results from first 13 months, discusses future improvements increase engagement project.
