    Antibiotic resistance genes - Antibiotics - Full-scale WWTP - Tertiary treatment - Treatment technology

    Information on the removal of antibiotics and ARGs in full-scale WWTPs (with or without additional treatment technology) is limited. However, it is important to understand the efficiency of full-scale treatment technologies in removing antibiotics and ARGs under a variety of conditions relevant for practice to reduce their environmental spreading. Therefore, this study was performed to evaluate the removal of antibiotics and ARGs in a conventional wastewater treatment plant (WWTP A) and two full-scale combined with additional treatment technologies. WWTP B, a conventional activated sludge treatment followed by an activated carbon filtration step (1-STEP® filter) as a final treatment step. WWTP C, a treatment plant using aerobic granular sludge (NEREDA®) as an alternative to activated sludge treatment. Water and sludge were collected and analysed for 52 antibiotics from four target antibiotic groups (macrolides, sulfonamides, quinolones, tetracyclines) and four target ARGs (ermB, sul 1, sul 2 and tetW) and integrase gene class 1 (intI1). Despite the high removal percentages (79–88%) of the total load of antibiotics in all WWTPs, some antibiotics were detected in the various effluents. Additional treatment technology (WWTP C) showed antibiotics removal up to 99% (tetracyclines). For ARGs, WWTP C reduced 2.3 log followed by WWTP A with 2.0 log, and WWTP B with 1.3 log. This shows that full-scale WWTP with an additional treatment technology are promising solutions for reducing emissions of antibiotics and ARGs from wastewater treatment plants. However, total removal of the antibiotics and ARGS cannot be achieved for all types of antibiotics and ARGs. In addition, the ARGs were more abundant in the sludge compared to the wastewater effluent suggesting that sludge is an important reservoir representing a source for later ARG emissions upon reuse, i.e. as fertilizer in agriculture or as resource for bioplastics or bioflocculants. These aspects require further research.

    This technical report discusses the research behind the findings and information on the role of agriculture in developing and maintaining the national ecological network presented in the Evaluation of the Nature Pact 2020, focusing on the ambitions in the Nature Pact for linking nature and economy and halting the decline in biodiversity, specifically in relation to the objectives of the national ecological network. The aim was to gain insight into how the provincial governments involve the agricultural sector in the realisation of the national ecological network, to assess the extent to which these approaches align with the characteristics and trends in agriculture, and to identify future directions the provinces can pursue for linking agriculture into the national ecological network.
    Eiwittransitie in perspectief: Duurzaam en gezond eten

    De Schijf van Vijf is hét advies van de overheid voor gezond en duurzaam eten in Nederland. Maar de overheid wil het voedselsysteem verder verduurzamen en stuurt daarom aan op een eiwittransitie: minder eiwit eten, waarvan een groter deel plantaardig eiwit. Dit kan gevolgen hebben voor de volksgezondheid, met name bij kwetsbare groepen.

    Antibiotic resistance genes - Antibiotics - River - Wastewater treatment plant
    Antibiotics are being used intensively for humans and livestock worldwide and have led to the presence of antibiotic resistance bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment. Wastewater treatment plants (WWTPs) have been identified as a point source for ARB&Gs, and water catchments consequently are potential receptors of ARB&Gs. The objective of this study was to investigate the occurrence of antibiotics (macrolides, sulfonamides, tetracyclines), ARGs (ermB, sul1, sul2, tetW), and class 1 integron (targeting the integrase gene), in a Dutch river that receives wastewater treatment plant effluent. Sediment and water samples were collected during one year along the river. The WWTP significantly increased the amounts of antibiotics and ARGs in the river as compared to the upstream samples, of which the antibiotics decreased once they entered the river. ARGs were persistent in the water and sediment from the WWTP effluent discharge point until 20 km downstream. This study provides insight in the prevalence of antibiotics and ARGs in a wastewater effluent-receiving river system in the Netherlands. Even though human antibiotic usage is low in the Netherlands, antibiotics, residues of antibiotics, and ARGs are detected in the river surface water-sediment system, which shows that a river has the potential to act as a reservoir of ARGs.

    In het Friese veenweidegebied verdwijnt het veen langzaam en daardoor daalt de bodem. Dit heeft gevolgen voor de natuur, landbouw en bebouwing. Wetterskip Fryslân, Provincie Fryslân en andere belanghebbenden hebben samen de veenweidevisie opgesteld. De visie schetst een duurzaam ontwikkelingsperspectief voor het veenweidegebied. Deze Storymap laat zien hoe gegevens uit de Basisregistratie Ondergrond (BRO) hebben bijgedragen tot begrip van de veendaling en het ontwikkelen van effectieve maatregelen.

    De 1392 locaties van de Landelijke Steekproef Kaarteenheden werden na circa 20 jaar opnieuw bezocht om onder meer het gehalte aan organische stof en de dichtheid te bepalen. Het gehalte aan organische stof in de laag van 0 tot 30 cm blijkt tussen circa 1998 en 2018 significant te zijn afgenomen: van 6,85 naar 6,43%. In de laag van 30 tot 100 cm werd een significante afname gevonden van 7,82 naar 5,11%. Ook de koolstofvoorraden in de Nederlandse bodem bleken in de periode tussen circa 1998 en 2018 significant te zijn afgenomen. Binnen 24 deelgebieden naar bodem en landgebruik kon in bijna alle gevallen geen significante verandering worden aangetoond. Voor het deel van Nederland dat op de bodemkaart als minerale grond is gekarteerd, kon ook geen significante verandering in het gehalte aan organische stof worden aangetoond. De resultaten geven aan dat een verklaring voor afname van het landelijk gemiddelde gehalte aan organische stof ligt in oxidatie van veen en moerig materiaal. Met de ervaringen van de meetcampagne in 2018 kan de toekomstige monitoring voor post-2020 LULUCF-rapportages ter hand worden genomen, waarbij aandacht nodig is voor de effecten van veranderend landgebruik, de effecten van diepe grondbewerking, veranderingen in bodemdichtheid en de hoogte van de koolstofratio (verhouding koolstof-organische stof). Bovendien geven de resultaten aan in welke gebieden een extra meetinspanning nodig is om nauwkeurige schattingen van koolstofvoorraden en veranderingen daarin te verkrijgen.

    In the pursuance of sustainable development, knowledge development and learning are often central activities. Moreover, this is organised in sustainability clusters that are groups of related companies that aim to increase the sustainability of their firms, value chains and territories, supported by stakeholders from public authorities, science, society and business. The thesis Territorial knowledge governance: pursuing sustainability in agriculture and food clusters aims to improve the understanding of the principles and to what extent of the coordination that is established through knowledge and learning in the pursuance of the sustainable development of agriculture and food clusters, or territorial knowledge governance. The thesis addresses two knowledge gaps: 1) the underrepresentation of the coordinative and transformative aspects of knowledge and learning in modes of governance literature and 2) the underrepresentation of a territorial-economic approach in the literature on the governance of sustainable development transitions, especially regarding knowledge and learning.

    The thesis makes use of on an iterative research design. Each research step consisted of theoretical explorations and case studies that were evaluated afterwards to select the next research activities. The data collection and analysis has two pillars: 1) a literature research on theories of modes of governance, knowledge, learning, innovation, and territorial development and 2) a comparative case study analysis.

    The thesis presents an analytical framework for analysing territorial knowledge governance, especially in relation to sustainable development and agriculture and food clusters. The coordinative principles of territorial knowledge governance have been defined in this framework as: 1) the setting of sustainable development missions, 2) the production and exchange of knowledge in supportive milieus, 3) the embedding of substantive knowledge, 4) the anchoring of significant knowledge, and 5) the feeding of the acquired significant knowledge into the (re-) design of institutions and strategies of policy design and implementation. Moreover, constraints, enablers and type of results are presented. It is concluded that territorial knowledge governance is especially suited to complex challenges, such as sustainable development, because it is able to open new pathways for sustainable development, through the establishment of alignment between cluster actors around a shared vision and mission that emerges during knowledge-based endeavours in the sustainable development in agriculture and food. Time-aspects and the institutions that enable or constraint territorial knowledge are identified as major issues for future research, especially in relation to the highly complex settings in which cluster actors act from perspectives, habits, capabilities, beliefs and ambitions that tend to oppose the implementation of sustainable territorial development missions.
