Citizen science new tool to empower vulnerable communities

Manila Bulletin 04 November 2020 | Ellalyn De Vera-Ruiz

Environment advocates are making use of citizen science as a unique opportunity for vulnerable communities to empower themselves with data and information amid the threats of chemical wastes to health and environment.

“Through the years, citizen science has developed into a practical and potent tool for helpless victims who often suffer in silence from the destructive pollution caused by powerful commercial and industrial interests,” Penchom Saetang, EARTH executive director and a citizen science practitioner for over 20 years, said in a statement.

Citizen science, as it is generally called, has become a strategic tool enabling communities impacted by chemical and waste problems to empower themselves with data and information that can be used to assert their rights to a healthy and safe environment.

A four-part online regional conference that commenced on Wednesday puts a spotlight on the application of citizen science in addressing, such problems affecting mostly poor and marginalized communities, with children, pregnant women and workers at greater risk. 

The International Pollutants Elimination Network-Southeast and East Asia (IPEN-SEA) virtual conference is co-organized by Nexus3 Foundation-Indonesia, EcoWaste Coalition-Philippines and the Ecological Alert and Recovery-Thailand with support from the Stockholm Environment Institute (SEI) and IPEN.  

“By developing their scientific knowledge, technical skills and critical abilities, pollution victims, or survivors rather, have found their voice and are able to use the results of their own studies to negotiate with polluters, defend their human rights in courts and advocate for policy reforms,” Saetang said.

“In citizen science, grassroots-based NGOs and community groups are the subject and the actors of the investigation, not a subject of a research project.  In many cases, the results of citizen science advocacy works contribute to policy changes at the local and national level,” said Yuyun Ismawati, co-Founder and senior adviser of Nexus3 Foundation.

Among the citizen science efforts presented were the monitoring of mercury concentrations in air in several healthcare facilities in Denpasar City, Bali, Indonesia, which eventually led to the issuance of a government policy withdrawing mercury-containing medical devices; the screening of playground equipment for lead content in Penang, Malaysia, which further drew attention to the urgency of adopting a regulation banning lead in paint; and the air sampling in Rayong Province, Thailand that detected excessive levels of air pollutants, including cancer-causing benzene and vinyl chloride, which prompted the government to issue a notification on the annual standard level of volatile organic compounds in ambient air for nine highly toxic chemical compounds.

The topic of how citizen science can be used in the context of the Sustainable Development Goals (SDGs) is growing in momentum, said Rachel Pateman, a researcher at SEI, University of York.  

The SDGs, which member states of the United Nations adopted in 2015, seek to end poverty and other deprivations, improve health and education, reduce inequality and spur economic growth, all while tackling climate change and preserving marine and terrestrial biodiversity.

“Citizen science can help in filling the data gaps to monitor the SDG indicators and in localizing indicator monitoring, especially in under-reported areas. It can help to bring to the fore issues of importance or concern to local communities that may have been missed in higher level discussions. And it can also be a way to bring together different stakeholders, including citizens, to build a shared understanding of and co-develop solutions to sustainability challenges,” Pateman said.
