Water and Sanitation discussions on the context of the 30th United Nations Climate Change Conference of the Parties

About this Research Topic

Background

Brazil was elected host country for the 30th United Nations Climate Change Conference of the Parties (COP 30) to be held in the city of Belém do Pará, Amazon Region, between November 10 and 21, 2025. The fact that it will be held in an urban area in the hearth of the Amazon rain forest is a powerful image of the importance of protecting environment despite urban development. This brings to light the importance of discussing several aspects of urban and environmental sustainability, in the 21st century.

The characteristics and roles of large cities reveal the constant and deeply interconnected relationships between local, national, and global dynamics. Urban spaces serve as arenas of conflict, innovation, and negotiation—socio-spatial processes that demand careful theorization. When it comes to basic sanitation services, as water supply and sewage management, development often produces unequal exposure to environmental risks and unequal access to safe water, particularly for socio-environmentally vulnerable populations and minority groups, producing scenarios of environmental injustice.

One of the trend topics to be discussed at COP30 is about how developed countries can provide financial support to developing countries for climate action. In this sense, may the water and sanitation topic be explored in the debates and also the privatization of water and sanitation services in general.

In this Research Topic, we aim to discuss issues about water supply and sanitation services universal access around the world, especially on how this topic will be addressed at COP 30, both by developed and developing countries that are still far from universal access to drinking water and basic sanitation.

In this sense, we expect that articles brings research, official data and information, recent water and sanitation policies and even reports from the COP 30 meetings, informing and discussing how COP 30 participants discussed the subject of water and sanitation.

The viewpoint of all authors involved in this topic will be highly considered for this research topic: participation of organized civil society, governments, legislative bodies, national and international committees and councils, media and journalists and private companies.

We welcome Original Research, Review, Policy and Practice Review, Brief Research Report, Case Report, Community Case Study, Mini Review, Perspective and Policy Brief articles.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
