The Danube Delta Living Lab: monitoring a transboundary wetland with open science

• November 10, 2026

Europe’s second-longest river meets the Black Sea in the Danube Delta, and the delta belongs to no single country. It straddles Romania and Ukraine, and the wider bioregion takes in the Danube basin, the Black Sea and surrounding areas of Ukraine, Romania and Moldova. Every monitoring programme here has to work across a border, which turns the choice of method into a governance decision as much as a scientific one.

Setup and partners

The Schmalhausen Institute of Zoology of the National Academy of Sciences of Ukraine coordinates the Danube Delta Open Living Lab and developed its framework. Supporting partners include the National Institute of Research and Development for Biological Sciences in Bucharest, the Royal Belgian Institute of Natural Sciences, the Technical University of Denmark and Lviv Polytechnic.

Much of the delivery is carried by regional institutions: the Institute of Marine Biology and the Institute of Hydrobiology of the National Academy of Sciences of Ukraine, the Ukrainian Scientific Centre of Ecology of the Sea, the Danube Biosphere Reserve, Kuyalnyk National Nature Park and the NGO Mare Nostrum. Field activity has had support from the Ukrainian Nature Conservation Group and Rewilding Ukraine.

The lab works as a collaborative system for cooperation, learning and action, pulling in research projects, innovation initiatives, local organisations, schools and residents, and it follows open science principles explicitly. [TO CONFIRM: the published material gives the launch as spring 2025 in one place and reports a launch in April 2026 in another.]

What open science means in practice here

The method is deliberately plain. Participants upload geotagged, time-stamped photographs to MINKA, the free citizen science platform created by Spain’s national research council, available as a website and a mobile app. It has been translated into Ukrainian, which is the difference between a tool that exists and a tool people use.

Data goes to Ukrainian researchers and, where the observer permits it, to the Global Biodiversity Information Facility. That consent step is not decoration. It keeps the contributor in control of where their observation ends up, and that is the condition on which voluntary monitoring carries on.

In a transboundary wetland the approach has a particular advantage. A photograph with coordinates and a timestamp can be verified by anyone, in any country, with no shared survey protocol to agree and no need for matching equipment. Where institutional cooperation is complicated, a common open platform does work a joint monitoring programme would struggle with.

The lab aims to reduce marine pollution, promote the circular economy and develop sustainable practices, with a longer-term ambition of making the delta a model for circular, resilient, community-driven development. Its bioregional approach links marine systems with water, energy, food and land waste management. In a delta that fits, because the line between marine and terrestrial management is mostly administrative anyway.

Invasive species as the central question

Invasive species are named as a pressure on the ecosystem, and the forward programme is built around them: building species data, tracking new arrivals, and watching how native and alien species interact.

Citizen science suits this well. Detecting a first arrival is a coverage problem rather than an analytical one, and many observers spread across a wide area will spot a new species before a periodic professional survey does. It is also where the limits appear. Photographic records can establish presence. They cannot establish abundance, rate of spread or competitive effect, and those need structured survey design, which the published material doesn’t describe at this site. Note too that eDNA, used at other PHAROS sites, is not mentioned in the Danube Delta material [TO CONFIRM: whether eDNA sampling is planned here].

Youth as the recruitment strategy

Engagement here has run through schools. More than 100 schoolchildren from the Odesa region attended a biological camp on the Syniukha River, and 15 of them completed a citizen science course, analysing their own results and producing posters that linked the work to a candidate site for Ukraine’s Nature Reserve Fund. More than 300 wildlife records were logged in July 2026.

In absolute terms, 300 records is a small dataset. Read as a conversion rate from a short course, it is a reasonable return, and the more durable output is a group of young people who now know what a verifiable observation is.

Building a Self-Sustaining Community of Practice for Species, Pollution and Ecosystem Resilience

Species data collection continues, along with tracking of new arrivals, monitoring of native-alien interactions, and the building of a community of practice that can carry on past the project. Alongside that sit pollution reduction through prevention and clean-up, a shift towards circular practices, and resilience-building in marine and terrestrial ecosystems.

The community of practice is the point. Where field science operates under real constraints, a distributed network of trained observers using a platform in their own language is monitoring capacity that doesn’t depend on a project continuing, as long as the platform stays available and somebody keeps using the data.
