We are increasingly confronted with severe social and economic impacts of environmental degradation all over the world. From a valuation perspective, environmental problems and conflicts originate from trade-offs between values. The urgency and importance to integrate nature's diverse values in decisions and actions stand out more than ever. Valuation, in its broad sense of ‘assigning importance’, is inherently part of most decisions on natural resource and land use. Scholars from different traditions -while moving from heuristic interdisciplinary debate to applied transdisciplinary science- now acknowledge the need for combining multiple disciplines and methods to represent the diverse set of values of nature. This growing group of scientists and practitioners share the ambition to explore how combinations of ecological, socio-cultural and economic valuation tools can support real-life resource and land use decision-making. The current sustainability challenges and the ineffectiveness of single-value approaches to offer relief demonstrate that continuing along a single path is no option. We advocate for the adherence of a plural valuation culture and its establishment as a common practice, by contesting and complementing ineffective and discriminatory single-value approaches. In policy and decision contexts with a willingness to improve sustainability, integrated valuation approaches can be blended in existing processes, whereas in contexts of power asymmetries or environmental conflicts, integrated valuation can promote the inclusion of diverse values through action research and support the struggle for social and environmental justice. The special issue and this editorial synthesis paper bring together lessons from pioneer case studies and research papers, synthesizing main challenges and setting out priorities for the years to come for the field of integrated valuation.JRC.D.2-Water and Marine Resource

Pour démontrer que le concept légal d’intérêts diffus est un instrument pour la justice et la démocratie environnementale, il faut tout d’abord le comprendre dans le contexte des fonctions sociales du procès judiciaire. Au-delà des intérêts individuels et de l’intérêt public, il existe dans certains systèmes juridiques, et en particulier dans celui des pays lusophones, une consécration des intérêts trans-individuels, dont les intérêts diffus sont une sous-catégorie. Le système d’action populaire est l’aboutissement de l’objectif de concrétisation de la protection des intérêts diffus sur le plan de la procédure juridictionnelle. La conséquence est une protection plus effective des droits environnementaux, à travers une représentation plus élargie.

Alongside production and consumption, bio-waste management is central to the food systems debate. To achieve sustainable food systems—an essential component of the Sustainable Development Goals and the world they envision—public authorities must address the shortage of current bio-waste-management policies and strive towards a new paradigm of bio-waste management, where environmental justice primarily informs policy design and decision making. In order to achieve fair environmental policies, particularly in the context of food systems and bio-waste management, it is essential to understand what drives public policy in these matters. In the present review, we seek to contribute by closing a gap in the literature by proposing a set of bio-waste-management drivers in the European context. Moreover, we focus on the “policy and legislation” driver, hoping to examine its main components and understand both their limitations and the opportunities they provide. Finally, we explore the role that co-creation can play as a facilitator of a public-governance paradigm that promotes sustainable development.
