Dataharvest 2026 - the European Investigative Journalism Conference

Comparing the size of glacier 100 years ago to today is a strong message on the impact of climate change without many words. This idea – to visualize gradual changes by contrasting the world some decades ago with today – can be a powerful way to engage new audiences for climate stories. Sources for this kind of structural analysis are often available but untapped: Old guide books, maps and other materials existing only in print.

Through an example on the industrialization of ski resorts, we will show how old guide books and other analog materials can be a treasure trove for climate journalists and how they can use it efficiently, even if the amount of paper seems intimidating.

In the session we will discuss potential story leads and which guide books (or similar) to look out for. In the second part, we will discuss strategies and tools to extract information and organize data, and tools that might be useful for extraction. We will also demonstrate how AI tools might help, where manual work is needed and which non-AI tools might speed up the work, even if you don’t consider yourself a data journalist.

Did you know: since July 2024, Members of the European Parliament (MEPs) have disclosed over 55,000 meetings with lobbyists and collectively declared more than 1,800 side jobs, including roles linked to registered EU lobby organisations? Or that of the over 23,000 lobby meetings disclosed by the European Commission, only less than one in five was held with civil society organisations? This expanding body of public data enables systematic analysis of lobbying exposure, conflicts of interest, and undue influence risks in EU decision-making, and has become a key resource for investigative reporting to break stories across the EU.

During this session, we will examine the practical investigative applications of Integrity Watch EU (IW EU), a near real-time transparency and data aggregation platform on the interactions between the private sector and over 2000 EU officials. IW EU collates all available data on MEP and European Commission lobby meetings, MEP side activities, and lobbyists registered on the EU’s Transparency Register. It is part of the wider IW eco-system of platforms, deployed in 23 European countries, enabling cross-border linkages with national integrity data such as political donations, lobby registers, or public procurement procedures.

Participants will receive a technical introduction to the new real-time monitoring features of IW EU, including its underlying data sources, legal disclosure frameworks, and analytical functionalities. We will go hands-on to learn how data sets can be queried, cross-referenced, and contextualised for investigative purposes. This session is suitable for beginners, and no data journalism knowledge is required.

Data journalists have traditionally thought of maps and spatial calculations as a job for special mapping software, like QGIS. But it's often more efficient to do GIS work within the same script that you perform the rest of your analysis.

In this session, you will see how easy it is to work with GIS within your code and share interactive maps with colleagues. To follow along, participants should have some experience in data journalism and a curiosity about the relationship between data and maps.

This session will introduce participants to a new world of possibilities for doing spatial analysis in code. While participants will benefit from simply observing, those who want to run the code should have R Studio installed https://posit.co/download/rstudio-desktop/
