Participatory assessment of French Reed Beds (FRB) as natural based solution for rural sanitation in arid environments: insights from Ouijjane project in Morocco
Published: 2025-08-16
Subjects: Civil and Environmental Engineering, Environmental Studies, Natural Resources Management and Policy, Water Resource Management
Rural improved sanitation remains a major challenge to achieving the UN SDG 6 goal. In this regard, this study evaluates, with local stakeholders, an operational rural sanitation project in Ouijjane commune, Morocco, using French Reed Bed (FRB) technology. Data from project documentation, as well as field interviews and focus group discussions, were used to carry out a participatory evaluation. [...]
Technological Adaptation Outpaces Climate Impacts on Aviation: Evidence from Three Decades of Warming
Published: 2025-08-08
Subjects: Civil and Environmental Engineering, Engineering, Environmental Engineering, Environmental Studies, Social and Behavioral Sciences
Climate impact assessments frequently prioritize projections over empirical validation of operational outcomes. We introduce and apply a generalizable empirical validation framework that (i) separates operational encounters from safety outcomes and (ii) tests climate → operations linkages via physical mechanism validation with explicit detectability bounds. Using 33 years (1991–2023) of U.S. [...]
“It is a sham process with participation.” Ten forms of citizen participation for sustainable development in the Norwegian Arctic
Published: 2025-07-31
Subjects: Environmental Studies
Achieving the Sustainable Development Goals (SDGs) requires action at all levels, from local to global, through synergy among all societal actors. Norway shares responsibility for SDG- based sustainable development with local authorities (municipalities and counties). The Planning and Building Act’s purpose clause stipulates that it shall promote sustainable development for the benefit of [...]
Iran’s Sustainability Gap: An Economic Analysis
Published: 2025-07-29
Subjects: Environmental Studies
Iran faces a widening sustainability gap as biocapacity stagnates while the ecological footprint expands. This study investigates how external debt, economic growth, natural resource rents, and renewable energy consumption affect the national load capacity factor—a composite index of biocapacity relative to ecological demand. Annual data for 1995–2023 were compiled from the World Bank and the [...]
Monetary transfers may be related to patterning in climate events, not just single extreme events
Published: 2025-07-25
Subjects: Climate, Environmental Studies, Physical and Environmental Geography, Remote Sensing
It is well-documented that households respond to climate events with climate adaptations: risk-management strategies like livelihood diversification, migration, or remittances – sending money and goods across distances. However, the focus is largely on responses to single climate events, while suggestive evidence indicates that temporal and spatial patterns across multiple events – including [...]
Navigating Rising Waters: Applying Protection Motivation Theory to Communities Facing Recurrent Flooding along the Shunganunga Creek
Published: 2025-07-24
Subjects: Atmospheric Sciences, Environmental Studies, Meteorology, Social and Behavioral Sciences
Floodplain communities face persistent and compounding challenges as climate change and urban development increase the frequency and severity of flooding events. This case study examines how residents living near the Shunganunga Creek floodplain in Topeka, Kansas, perceive recurring flood risks and respond to current communication strategies. Using 11 semi-structured interviews analyzed through [...]
Conservation is Coherence: Introducing the Negawatt Philosophy of Lawful Design
Published: 2025-07-10
Subjects: Civil and Environmental Engineering, Ecology and Evolutionary Biology, Environmental Studies, Natural Resources and Conservation, Operations Research, Systems Engineering and Industrial Engineering, Other Environmental Sciences, Other Physics, Other Planetary Sciences, Sustainability, Systems Biology
This paper articulates the Negawatt Philosophy, reframing conservation not as omission or moral restraint, but as the structural intelligence that sustains life and preserves biospheric coherence. Modern economies valorise extraction and combustion while treating conservation as invisible absence. Yet thermodynamics reveals life as negentropy—an ordering that defies the drift into entropy’s [...]
Embedding Symbolic Power in the Relational Turn
Published: 2025-07-04
Subjects: Environmental Studies
Understanding how nature’s values become institutionalised, while others are marginalised, is central to advancing sustainability transformations. The relational turn in sustainability science is centred around the coconstitutive dynamics of human–nature relationships. Yet, it has so far paid limited attention to the power relations that shape which values gain legitimacy or are marginalised. We [...]
River Network HyperGraphs and Transportation Network HyperGraphs: A Graph-Theoretic Approach for Geoscientific and Civil Applications
Published: 2025-07-03
Subjects: Applied Mathematics, Civil Engineering, Environmental Studies, Life Sciences, Mathematics, Other Life Sciences, Other Mathematics, Physical Sciences and Mathematics, Social and Behavioral Sciences
River Network Graphs and Transportation Network Graphs are classical models that represent river systems and transportation infrastructures as vertices and edges, respectively, and underpin applications in hydrological simulation, watershed management, shortest-path computation, and urban traffic analysis. In this paper, we extend these graph-based models into the hypergraph and superhypergraph [...]
‘You can’t blame people for risky choices if there are no better options’: Household water safety in the Dominican Republic
Published: 2025-07-02
Subjects: Environmental Studies
Household water insecurity, fractured systems of water delivery, and intermittent water supply hamper efforts to ensure that the water households consume is safe. Household water treatment and safe storage are often advocated as effective, rapidly deployed, and cost-effective solutions to these problems. However, the effectiveness of these measures and household compliance with them often degrade [...]
The air pollution benefits of low severity fire
Published: 2025-07-02
Subjects: Environmental Studies, Forest Sciences, Remote Sensing
Larger and more frequent wildfire events in Western North America in recent years have resulted in extensive human and environmental damage, and are reversing decades of air quality improvements. Fuels treatments, including the use of prescribed fire, can reduce the extent and severity of future wildfires, but air quality trade-offs resulting from application of these treatments -- more initial [...]

Food security beyond borders: how crop imports affect drought risk of conflict-affected countries
Published: 2025-06-25
Subjects: Agricultural Science, Agriculture, Climate, Environmental Studies, Hydrology, Meteorology, Natural Resources Management and Policy, Sustainability
Drought events can disrupt food security and increase the risk of violent conflicts. In an interconnected global food system, countries rely on both local food production and imports to meet domestic demand. When assessing the impact of drought risk on national food security, however, imported crops are often overlooked. This study incorporates international crop trade information to understand [...]
Gamified Learning for Sustainable Eating: Exploring the Role of Prior Knowledge and Readiness to Change
Published: 2025-06-14
Subjects: Environmental Studies
Background: Dietary habits play a central role in the transition toward a more sustainable food system. However, many consumers lack an understanding of the principles of sustainable eating. Objective: This study examined whether a gamified quiz could enhance knowledge about the environmental impact of food. Additionally, it explored the role of prior knowledge and readiness for change, based on [...]
Bridging the Macro-Micro Divide through a New Paradigm for Climate Resilience Assessment in Data-Scarce Regions
Published: 2025-06-04
Subjects: Environmental Studies
Efforts to assess climate resilience in low-income countries (LICs) are often hampered by fragmented data systems and analytical silos between national and local scales. This study proposes and operationalizes an integrated empirical framework that bridges macroeconomic econometric modeling and micro-level spatial analysis to measure and visualize climate resilience in data-scarce settings. Using [...]
