Illuminating the collective learning continuum in the Colorado River Basin Science‐Policy Forums

Environmental Policy and Governance, Journal Year: 2024, Volume and Issue: unknown

Abstract Although considerable research over the past two decades has examined collective learning in environmental governance, much of this scholarship focused on cases where occurred, limiting our understanding drivers and barriers to learning. To advance knowledge what we call “collective continuum,” compare was not found occur or its effects were “blocked.” Through semi‐structured interviews with key stakeholders science‐policy forums Colorado River Basin, a large complex river basin western North America, examine differences patterns that explain moments learning, blocked non‐learning, drawing insights from framework. Our results find various factors influence non‐learning. We discover technical social as common both In contrast, more structural associated At same time, reveal about role political factors, such timing, legal constraints, priorities, which are underdeveloped Overall, these findings theoretical continuum offer practical may strengthen coordination science management for effective governance within Basin.

Socio-ecological analysis of the eutrophication in Chesapeake Bay, USA

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: Sept. 8, 2023

This study is a social-ecological analysis of eutrophication in the Chesapeake Bay, United States America (USA). It uses an expanded DPSIR framework (Drivers/Pressures/State/ Impacts/Responses) methodology to analyze issue. In addition, typology social actors and stakeholders socio-economic part system identified. These include residents, agriculturists, fishers, real estate developers, tourism operators, scientific researchers, state federal regulators. The results found that Drivers are food security, housing, economic development, recreation pursuits, sense belonging, population growth. result human Activities such as land coastal change for coastline changes fisheries, urban or suburban burning fossil fuels, agricultural fertilization. activities exert Pressures wastewater discharge, runoff from cleared land, atmospheric deposition (NOx), nutrient input, decreased tidal vegetation, overfishing filter feeders. alterations State environment its resilience by increasing duration areal extent hypoxia, turbidity, ratios. also causes ecosystem changes, decrease wildlife diversity, affects services, decreasing buffering. health Bay benefits all wildlife, so reduction services Impacts on society’s welfare well-being, economy, environmental justice.

National Forest City Policy and Urban Ecological Resilience: Evidence from 292 Cities in China

Forests, Journal Year: 2024, Volume and Issue: 15(11), P. 1906 - 1906

Published: Oct. 29, 2024

The process of sustainable urban development faces complex and severe environmental problems. Therefore, enhancing ecological resilience (UER) has become an urgent critical goal. In this study, the establishment national forest cities (NFCs) in China is regarded as exogenous shock event, impact NFCs on UER its mechanisms are investigated based data from 292 spanning 2003 to 2021 using a difference-in-difference method. It found that can significantly enhance UER, conclusion holds after series robustness tests. Mechanism analysis shows effectively strengthen regulations, upgrade industrial structures, promote green innovation, thus UER. Heterogeneity indicates effect NFC more significant low-carbon non-pilot cities, with higher levels development, central western China. Spatial spillover improve neighboring cities. should be continuously implemented optimized establish long-term mechanism for forests resilience.
