Compensation for Environmental Services and Rural Communities: Lessons from the Americas

In principle, payments for environmental services – such as watershed management, biodiversity conservation, and carbon sequestration – can advance the goals of both environmental protection and poverty reduction. A review of recent initiatives in the Americas suggests, however, that this desirable combination is not automatic. If payments for environmental services (PES) schemes are to be an effective vehicle for strengthening livelihoods in poor rural communities, they must be designed with that objective firmly in mind. This paper draws key lessons from diverse experiences in Costa Rica, Mexico, Brazil, El Salvador, and New York.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Interaction of metal and slag in continuous casting mold.

Knowledge of the flow field inside the mold can offer an opportunity to improve the internal cleanness of the final product. The PIV technique was employed to assess the distribution of longitudinal velocity distribution along a wide section ranging from the submerged nozzle entry to the narrow surface of a mold in a slab casting machine, as well as the distribution of transverse velocity component. This information can be used to assess the degree of interfacial turbulence and also to characterize transient phenomena in the mold
