    Rivers in developed regions are under significant stress due to nutrient enrichment generated mainly by human activities. Excess nitrogen and phosphorus emissions are the product of complex dynamic systems influenced by various factors such as demographic, socio-economic and technological development. Using a Catalan river catchment, La Tordera (North-East of Spain), as a case study of an integrated and interdisciplinary environmental assessment of nutrient flows, we present and discuss the development of narrative socio-economic scenarios through a participatory process for the sustainable management of the anthropogenic sources of nutrients, nitrogen and phosphorus. In this context, scenarios are an appropriate tool to assist nutrient emissions modelling, and to assess impacts, possible pathways for socio-economic development and associated uncertainties. Evaluated against the 1993–2003 baseline period, scenarios target the 2030 horizon, i.e. through the implementation process of the Water Framework Directive (Directive 2000/60/EC). After a critical examination of the methodology used in the participatory development of socio-economic scenarios, we present four possible futures (or perspectives) for the Catalan river catchment conceived by stakeholders invited to a workshop. Keys to the success of such a participatory process were trust, which enhanced openness, and disagreements, which fostered the group's creativity for scenario development. The translation of narrative socio-economic scenarios into meaningful nutrient emission scenarios is also discussed. By integrating findings of natural sciences and socio-economic analysis, we aim to assist decision makers and stakeholders in evaluating optimal management strategies for the anthropogenic sources of nitrogen and phosphorus

    Between activism and science: Grassroots concepts for sustainability coined by Environmental Justice Organizations

    textabstractAbstract In their own battles and strategy meetings since the early 1980s, EJOs (environmental justice organizations) and their networks have introduced several concepts to political ecology that have also been taken up by academics and policy makers. In this paper, we explain the contexts in which such notions have arisen, providing definitions of a wide array of concepts and slogans related to environmental inequities and sustainability, and explore the connections and relations between them. These concepts include: environmental justice, ecological debt, popular epidemiology, environmental racism, climate justice, environmentalism of the poor, water justice, biopiracy, food sovereignty, "green deserts", "peasant agriculture cools downs the Earth", land grabbing, Ogonization and Yasunization, resource caps, corporate accountability, ecocide, and indigenous territorial rights, among others. We examine how activists have coined these notions and built demands around them, and how academic research has in turn further applied them and supplied other related concepts, working in a mutually reinforcing way with EJOs. We argue that these processes and dynamics build an activist-led and co-produced social sustainability science, furthering both academic scholarship and activism on environmental justic
