Blue Papers was set up to connect academic and practical analysis of water, culture, heritage and sustainable development and provide concepts, methodologies and case studies to guide policymakers in developing value-based decisions and strategies. The first five issues of the journal brought together over 130 authors from academia, practice, private sector, major public institutions and NGOs. Their insights from multiple sectors and scientific fields – including policymaking, governance, water management, biology, urban planning, heritage and history – shed light on global and local dynamics, challenges and approaches to contemporary urgencies in the water sector and their impact on space, society and culture. The 85 articles so far published in Blue Papers have explored examples from 31 countries, highlighting positive and negative aspects of governance, historical processes and socio-cultural practices related to water.@en

Taking an integrated approach to problems involving water, culture, heritage, and sustainable development can be especially complicated depending on the water body at stake. Oceans, lakes, rivers and canals all require specific approaches. This issue of Blue Papers takes particular interest in rivers as agents of interaction between water and land, culture and nature, and as carriers and connectors of multiple, often very different challenges.@en

In March 2023, thousands of people from various disciplines came together in New York for the United Nations 2023 Water Conference. The attendees included policymakers, activists, professionals and academics, all with an interest in the water sector. The conference provided a platform to share knowledge and exchange ideas about water-related challenges. Through a combination of in-house and side events, participants were provided with the opportunity to voice their concerns, engage in crucial discussions and exchange novel insights, despite the predominantly scripted nature of the event as a forum tailored for politicians and policymakers. The Water Conference identified risks ensuing from the number of short-term commitments, unclear funding and the lack of quantifiable measurements (President of the General Assembly 2023). The Water Conference also saw the adoption of the Water Action Agenda (United Nations 2023), consisting of voluntary commitments in line with UN Sustainable Development Goals (SDGs) and focusing on water. Crafting these commitments posed a challenge, highlighting the complex nature of the United Nations’ efforts in fostering collaboration among people representing diverse backgrounds, interests, cultures and histories.@en
