Abstract Transitional waters, described as critical transition zones because of their position at terrestrial, freshwater and marine interfaces, provide essential goods services to the biosphere including human populations. These ecotones face increasing influence mainly due population density increase in coastal areas. water bodies have, date, received little attention development ecological status indicators; this is a deficiency when trying meet Water Framework Directive objective all...

This study analyzes the factors that have facilitated Vietnam's recent rapid solar and wind power expansion draws policy insights for other member states of Association Southeast Asian Nations (ASEAN). A policy-mix analysis focusing on targets, incentive instruments, enabling regulations, implementation is carried out, informed by semi-structured interviews with 20 Vietnamese experts during period January–March 2021. comparative between Vietnam ASEAN countries provides insights. Generous...

Rapid increases in electricity consumption Southeast Asia caused by rising living standards and population raise concerns about energy security, affordability environmental sustainability. In this study, the role of short-term off-river storage (STORES) supporting 100% renewable is investigated. Large-scale integration off-river, closed-loop pumped hydro a new approach to providing system flexibility facilitating high penetration variable systems. The features STORES include large potential,...

At the United Nations Framework Convention on Climate Change 26th Conference of Parties (COP 26) in November 2021, Vietnam pledged to phase out unabated coal power by 2040s or as soon possible thereafter. Achieving this will require major efforts. This study investigates drivers for Vietnam's phase-out decision, barriers achieving a successful thermal out, and potential strategies achieve pledge. To end, survey 43 experts from government agencies, research institutions, civil society,...

Abstract Transitional waters are ecotones between terrestrial, freshwater and marine ecosystems, being characterized by high spatial heterogeneity temporal variability. The EU Water Framework Directive (WFD) posed to the scientific community challenge classify these ecosystems into a small number of types, while retaining functional classification ecosystem types. A niche theory approach is proposed identify limiting forcing factors organizing biological quality elements, i.e. dimensions....

Abstract This paper offers essential insights into Southeast Asiaʼs transition to clean energy, a cornerstone for global climate objectives. Based on 27 interviews with regional energy and experts conducted between September 2022 October 2023, the research distils key factors 3Ds: Demanding, Doable, Dependent. Highlighting these aspects would foster readiness, persuade stakeholders, secure international support, all of which are pivotal advancing towards net‐zero emissions in Asia.

Abstract Aim To analyse the relationship between fish species richness and salinity, to provide a simple linear model for diversity trends across salinity gradients in tropical coastal lagoon that can be compared with other similar ecosystems communities. reinforce our conclusions, salinity–fish was investigated at different spatial scales (sampling station, set of stations whole lagoon) two periods, separated by 18 years. Location The Terminos lagoon, shallow (mean maximum depths ranging...

ABSTRACT A lack of information on environmental protection values, especially non-market has contributed to wetland degradation in the Mekong River Delta. To fill this gap, study uses choice modelling estimate biodiversity values Tram Chim National Park, a typical ecosystem The estimated net social benefit proposed program ranges from USD0.52 million USD1.84 million. This suggests that program's implementation would improve welfare. Some issues, including use focus groups, aspects...

This study assesses key barriers to offshore wind power (OWP) development in Vietnam and policy options for the of sector. A survey 39 experts from government agencies, research institutions, industry, civil society plus 22 follow-up interviews were conducted over January–September 2021, coupled with a broader analysis options. The finds that an underdeveloped environment, incomplete procedures, infrastructure supply chain immaturity are current OWP Vietnam. Recommended measures include: 1)...

Forests face increased threats from multiple hazards, with clear evidence of rising levels disturbance across the world. In Europe part this is increasing areas forest continent, due to management forests, and changing climate. Recently damage have become alarming, windstorms causing catastrophic damage, fires appearing in new unexpected locations, extended droughts followed by bark beetle infestations leading very high mortality Norway spruce Central Europe.The agents that affect forests...

1 - As a consequence of their location between land and open sea, coastal lagoons are subject to strong anthropogenic pressures due tourism and/or heavy shellfish/fish farming. Furthermore, they receive fresh water from catchment areas loaded with urban, agricultural industrial effluents domestic sewages. 2 These responsible for important ecosystem alterations i.e. eutrophication, bacterial contamination, algal blooms (toxic or not), anoxia fish kills. Further, additional problems arise...

This paper investigates options for carbon price adoption in Vietnam, with a focus on model designs capable of meeting the country's updated Nationally Determined Contribution (NDC).We employ an ex-ante policy evaluation across environmental, economic, social, and political dimensions, drawing interviews key stakeholders.A multi-criteria analysis is also pursued to provide overall comparison options.The findings indicate that relatively low but increasing could play important role steering...

Species are identified as bioindicators when their presence or abundance within sites of a particular habitat conservation area high. Dufrêne and Legendre (1997), Ecological Monographs 67: 345–366, proposed the use flexible asymmetrical approach to detect indicator species assemblages characterizing groups sites, value for each being subsequently tested by randomization. Although advantages these methods in comparison other multivariate two-way analyses have been demonstrated, relatively few...

Abstract Cumulative relative biomass trophic level spectra (BTLS) are constructed for the fish community of a tropical coastal lagoon in Mexico to analyse spatio-temporal patterns as potential ecosystem indicator multifactor impacts. Data were based on monthly trawl surveys over single year carried out eighteen years apart. The show significant differences between two periods, indicating major shifts structure system. Specifically, omnivorous, estuarine species middle foodweb (originally...

The world faces critical water risks in relation to availability, yet demand is increasing most countries. To respond these risks, some governments and authorities are reforming their governance frameworks achieve convergence between supply ensure freshwater ecosystem services sustained. assist this reform process, the Water Governance Reform Framework (WGRF) proposed, which includes seven key strategic considerations: (1) well-defined publicly available objectives; (2) transparency...

Abstract Systemic threats to food‐energy‐environment‐water systems require national policy responses. Yet complete control of these complex is impossible and attempts mitigate systemic risks can generate unexpected feedback effects. Perverse outcomes from emerge the diverse responses decision‐makers across different levels scales resource governance. Participatory risk assessment processes help planners understand subnational dynamics ensure that policies do not undermine resilience...

Asia is facing serious environmental challenges including urban air pollution and the effects of global climate change. As a major source greenhouse gases, what happens in will play crucial role determining extent to which world warms over coming decades. This paper reviews key faced by region growing opportunities for transition cleaner economy powered zero‐emission energy sources. Economic mechanisms – emissions pricing, reverse auctions, renewable portfolio standards with green...
