'Debating' nature conservation: policy, law and practice in Indonesia: a discourse analysis of history and present

This book is about the politics of nature conservation in late New Order and early Reformasi Indonesia. It approaches the subject through discourse analysis. Understanding politics as a struggle for discourse hegemony it analyses both processes of policy- and lawmaking in Jakarta and of implementation in national parks, and their outcomes, and addresses a number of questions: Which discourses have dominated conservation policies and laws throughout history? How did Ministers, members of Parliament, state officials, NGOs and residents of national parks try to decide debates on conservation in their advantage? Which unwritten rules helped or constrained them in this effort? How did the struggle for discourse hegemony affect policy and law, policy- and lawmaking and implementation? Based on rich empirical case material the book argues that a multitude of discourses have come to co-exist which enabled actors to use arguments strategically, and that various actors have succeeded to mobilise discourses enabling them to participate in the debate without obligations. The results of this study go beyond participating in the debate on what element of sustainable development to focus on but link the policy debate to the debate on governance and rule of law.Effective Protection of Fundamental Rights in a pluralist worl

Prioritization Approaches for Substances of Emerging Concern in Groundwater:A Critical Review

Risks from emerging contaminants (ECs) in groundwater to human health and aquatic ecology remain difficult to quantify. The number of ECs potentially found in groundwater presents challenges for regulators and water managers regarding selection for monitoring. This study is the first systematic review of prioritization approaches for selecting ECs that may pose a risk in groundwater. Online databases were searched for prioritization approaches relating to ECs in the aquatic environment using standardized key word search combinations. From a total of 672, 33 studies met the eligibility criteria based primarily on the relevance to prioritizing ECs in groundwater. The review revealed the lack of a groundwater specific contaminant prioritization methodology in spite of widely recognized differences between groundwater and surface water environments with regard to pathways to receptors. The findings highlight a lack of adequate evaluation of methodologies for predicting the likelihood of an EC entering groundwater and knowledge gaps regarding the occurrence and fate of ECs in this environment. The review concludes with a proposal for a prioritization framework for ECs in groundwater monitoring that enables priority lists to be updated as new information becomes available for substances with regard to their usage, physicochemical properties, and hazards

Biological and synthetic surfactant exposure increases antimicrobial gene occurrence in a freshwater mixed microbial biofilm environment

Publication history: Accepted - 8 March 2023; Published - 17 March 2023.Aquatic habitats are particularly susceptible to chemical pollution, such as antimicrobials, from domestic, agricultural, and industrial sources. This has led to the rapid increase of antimicrobial resistance (AMR) gene prevalence. Alternate approaches to counteract pathogenic bacteria are in development including synthetic and biological surfactants such as sodium dodecyl sulfate (SDS) and rhamnolipids. In the aquatic environment, these surfactants may be present as pollutants with the potential to affect biofilm formation and AMR gene occurrence. We tested the effects of rhamnolipid and SDS on aquatic biofilms in a freshwater stream in Northern Ireland. We grew biofilms on contaminant exposure substrates deployed within the stream over 4 weeks. We then extracted DNA and carried out shotgun sequencing using a MinION portable sequencer to determine microbial community composition, with 16S rRNA analyses (64,678 classifiable reads identified), and AMR gene occurrence (81 instances of AMR genes over 9 AMR gene classes) through a metagenomic analysis. There were no significant changes in community composition within all systems; however, biofilm exposed to rhamnolipid had a greater number of unique taxa as compared to SDS treatments and controls. AMR gene prevalence was higher in surfactant-treated biofilms, although not significant, with biofilm exposed to rhamnolipids having the highest presence of AMR genes and classes compared to the control or SDS treatments. Our results suggest that the presence of rhamnolipid encourages an increase in the prevalence of AMR genes in biofilms produced in mixed-use water bodies.EPSRC, Grant/Award Number: EP/P032427/1; University of Ulste
