\nBeyond the myth of the \u201cTop Three\u201d<\/h2>\n\n\n\n

On the week of 26 May 2025, ten authors* of Chapter 2 of the IPBES Nexus Assessment<\/a> gathered at the Luxembourg Centre for Socio-Environmental Systems (LCSES)<\/a>. IPBES \u2013 Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services \u2013 advises the United Nations Convention on Biological Diversity. Its IPBES Nexus Assessment, released in December 2024 at the plenary in Namibia, explores the interlinkages among biodiversity, water, food, climate and health.<\/p>\n\n\n\n

Over four days, the international working group worked collaboratively on scientific publications based on the Assessment. Hosted at the historic Maison Schuman<\/a> in Luxembourg, the team also opened its doors to the public with a seminar sharing key insights and reflections five months after the report\u2019s release.<\/p>\n\n\n\n

\nThe question everyone asks<\/h3>\n\n\n\n

As Prof. Ralf Seppelt<\/a>, IPBES coordinating lead author from the University of Luxembourg, noted: \u201cPeople often ask us: What are the top three things to do? The truth is\u2014there is no such list.\u201d <\/em> Solutions exist, but they are interconnected and context-dependent. The key element of success is collaboration and acknowledging that things are interrelated in an environmental polycrisis.<\/p>\n\n\n\n

Prof. Pamela McElwee<\/a>, Co-Chair of the Assessment from the State University of New Jersey, USA (see photo below), explained that the report synthesised 71 actionable solutions from 6,500 scientific publications, each evaluated for its impact across the five Nexus elements. The message is clear: addressing issues in isolation no longer works. Interdisciplinary and interministerial cooperation is essential.<\/p>\n\n\n

\nFrom data to decisions<\/h3>\n\n\n\n

The scientific challenge now is to map cause-and-effect interactions across at least three Nexus elements using global data and trend analysis. This approach promises greater impact than tackling problems one by one. It also opens opportunities for technological innovation and for embedding solutions into new socio-economic models and behavioural shifts.<\/p>\n\n\n

\nFunding and implementation<\/h3>\n\n\n\n

Beyond identifying solutions, the report outlines pathways for change \u2013 starting with funding models. Current investments in climate mitigation often overlook biodiversity impacts. To bridge this gap, IPBES teams are developing decision-support tools to identify barriers and drivers of change. A database of 200 such tools will be released soon. <\/p>\n<\/div>\n\n\n\n

\nHealth as a driver<\/h3>\n\n\n\n

Prof. David Hayman<\/a>, Coordinating Lead Author from Massey University, New Zealand, highlighted how drivers of biodiversity loss and human health are deeply linked. Emerging signals include:<\/p>\n\n\n\n
