Advancing the contributions of European stakeholders in farming systems to transitions to agroecology

The concept of a ‘just transition’ is gaining traction in international policy discourses. It has particular significance in relation to achieving net zero greenhouse gas emissions and the need for ensuring rights and responsibilities of all actors in transitions to agroecological farming systems. Research plays an important role in accompanying this transformation. It explores pathways for more sustainable and fair food systems, barriers to them being achieved, and where and what risks arise for communities of interest and of place. Researchers and practitioners across levels and sectors were brought together in H2020 projects LIFT and UNISECO using processes of stakeholder engagement. Both projects analysed the perceptions of actors towards agroecological farming, and their active involvement in the transitions required. This article summarises lessons learnt regarding multi‐actor engagement in different participatory settings in both projects, including a Multi‐Actor Platform approach, Q method, DELPHI and Hybrid forum workshops. The interactions involved several hundred actors from 18 countries across Europe. The article reflects on implications of the Covid‐19 pandemic on the processes and effectiveness of multi‐actor engagement, and assessments of the impacts on the empowerment of the actors. The findings are contextualised by contemporary European Union and national policy objectives of tackling climate change, the loss of biodiversity, and inequalities

Entwicklung und Operationalisierung eines Zielkonzepts zur Erreichung gesellschaftlich erwünschter Biodiversitätsziele in der Agrarlandschaft

Der Biodiversitätsschwund in Agrarlandschaften wird mittlerweile von einer breiten Öffentlichkeit und politisch vielfältig diskutiert. Forderungen, den Trend zu stoppen oder umzukehren, finden zunehmend Gehör. Jedoch herrscht weitgehend Unklarheit darüber, welche konkreten Veränderungen es in welcher Größenordnung in Agrarlandschaften bedarf, um den Biodiversitätsschwund zu stoppen und eine Trendumkehr zu erreichen.In der hier vorgestellten Forschungsarbeit werden Biodiversitätsziele für die Agrarlandschaft definiert und ein Zielkonzept entwickelt, welches Kriterien enthält, die a) aus ökologischer Sicht die Erreichung dieser Ziele erwarten lassen und b) für die Agrarlandschaft konkret anwendbar sind (Operationalisierbarkeit). Ergebnis ist das Konzept ‚Biodiversitätsziele für Agrarlandschaften‘ und seine konkrete Anwendung auf vier Beispielbetrieben

Blood volume-monitored regulation of ultrafiltration in fluid-overloaded hemodialysis patients: study protocol for a randomized controlled trial

Abstract Background Data generated with the body composition monitor (BCM, Fresenius) show, based on bioimpedance technology, that chronic fluid overload in hemodialysis patients is associated with poor survival. However, removing excess fluid by lowering dry weight can be accompanied by intradialytic and postdialytic complications. Here, we aim at testing the hypothesis that, in comparison to conventional hemodialysis, blood volume-monitored regulation of ultrafiltration and dialysate conductivity (UCR) and/or regulation of ultrafiltration and temperature (UTR) will decrease complications when ultrafiltration volumes are systematically increased in fluid-overloaded hemodialysis patients. Methods/design BCM measurements yield results on fluid overload (in liters), relative to extracellular water (ECW). In this prospective, multicenter, triple-arm, parallel-group, crossover, randomized, controlled clinical trial, we use BCM measurements, routinely introduced in our three maintenance hemodialysis centers shortly prior to the start of the study, to recruit sixty hemodialysis patients with fluid overload (defined as ≥15% ECW). Patients are randomized 1:1:1 into UCR, UTR and conventional hemodialysis groups. BCM-determined, ‘final’ dry weight is set to normohydration weight −7% of ECW postdialysis, and reached by reducing the previous dry weight, in steps of 0.1 kg per 10 kg body weight, during 12 hemodialysis sessions (one study phase). In case of intradialytic complications, dry weight reduction is decreased, according to a prespecified algorithm. A comparison of intra- and post-dialytic complications among study groups constitutes the primary endpoint. In addition, we will assess relative weight reduction, changes in residual renal function, quality of life measures, and predialysis levels of various laboratory parameters including C-reactive protein, troponin T, and N-terminal pro-B-type natriuretic peptide, before and after the first study phase (secondary outcome parameters). Discussion Patients are not requested to revert to their initial degree of fluid overload after each study phase. Therefore, the crossover design of the present study merely serves the purpose of secondary endpoint evaluation, for example to determine patient choice of treatment modality. Previous studies on blood volume monitoring have yielded inconsistent results. Since we include only patients with BCM-determined fluid overload, we expect a benefit for all study participants, due to strict fluid management, which decreases the mortality risk of hemodialysis patients.
