Direction, not detail: Progress towards consensus at the fourth intergovernmental conference on biodiversity beyond national jurisdiction.

After a two year delay caused by the COVID-19 pandemic, the fourth intergovernmental conference (IGC-4) in the negotiations for a new UN treaty to address the conservation and sustainable management of biodiversity beyond national jurisdiction (BBNJ) took place in March 2022. This meeting differed substantially from previous IGCs in terms of process, with much of the discussions occurring in 'informal informals,' or off-the-record meetings open only to delegates and registered observers. Additionally, in-person participation was extremely limited and observers only had access to web broadcasts, i.e., no in-person interactions with delegates. A draft text of the treaty was circulated in advance and provided the basis for discussion and negotiation at the meeting. This paper examines IGC-4 in line with previous analyses of the first three IGCs, tracing the process and outcomes to date, aiming to understand the factors and players that are building a new BBNJ agreement. Key themes explored include marine genetic resources (MGRs), area-based management tools, including marine protected areas (ABMTs/MPAs), environmental impact assessment (EIA), and capacity building and transfer of marine technology (CB/TMT). Some progress toward consensus has been made, buoyed by intersessional discussions, but several sticking points remain with regard to definitions, content, and processes enshrined in the draft treaty, and a fifth IGC is scheduled to take place from 15 to 26 August 2022.

Missing marine protected area (MPA) targets: How the push for quantity over quality undermines sustainability and social justice.

International targets for marine protected areas (MPAs) and networks of MPAs set by the World Summit on Sustainable Development and United Nations Convention on Biological Diversity failed to meet their 2012 deadline and have been extended to 2020. Whilst targets play an important role in building momentum for conservation, they are also responsible for the recent designation of several extremely large no-take MPAs, which pose significant long-term monitoring and enforcement challenges. This paper critically examines the effectiveness of MPA targets, focusing on the underlying risks to achieving Millennium Development Goals posed by the global push for quantity versus quality of MPAs. The observations outlined in this paper have repercussions for international protected area politics with respect to (1) the science-policy interface in environmental decision-making, and (2) social justice concerns in global biodiversity conservation.

Wealth blindness beyond national jurisdiction.

Marine genetic resources (MGR) are a new issue in high seas management. Discussion on how to best manage these resources is currently ongoing at the United Nations, within the context of a proposed treaty on the conservation and sustainable use of marine 'Biodiversity Beyond National Jurisdiction' (BBNJ), which is expected to be completed in 2020.But how accurately can states measure the potential economic value of resources that still do not have a clear market application? Developing states in particular already suffer from wealth blindness, where they lack the capacity to properly evaluate the economic value or market potential of their marine resources. This article explores the extent to which wealth blindness forms the backdrop to the current debates over the potential for profitably exploiting marine genetic resources, as well as how this relates to demands for capacity building and technology transfer in the BBNJ treaty negotiation process.

Relevance of medical comorbidities for functional mobility in people with limb loss: retrospective explanatory models for a clinical walking measure and a patient-reported functional outcome.

OBJECTIVES: Various modifiable and non-modifiable factors affect functional mobility, but subjective patient-reported and objective performance-based measures are rarely combined in explanatory analyses of functional mobility in people with limb loss. This study determined separate explanatory models for patient-reported function using the Prosthetic Evaluation Questionnaire Mobility Subscale (PEQ-MS), and performance-based 2-Minute Walk Test (2MWT). DESIGN: Retrospective cross-sectional observational analysis. SETTING: Wellness-walking program. PARTICIPANTS: Three hundred five volunteers with lower limb loss participated. Sixty nine percent were men, mean age 56 (15) years. Fifty two percent had vascular amputation causes, 42% had surgical levels above the knee, and 82% had medical comorbidities. Walking levels included limited-household (21%), limited-community (30%), and independent-community (49%). Outcome measures included patient-reported PEQ-MS, Activities-specific Balance Confidence (ABC) and Houghton scales; and performance-based balance and walking. MAIN OUTCOMES: Separate PEQ-MS and 2MWT multiple regression models fit using backward deletion. RESULTS: Modifiable (balance ability, ABC, Houghton score; P<0.05) and non-modifiable factors (sex, amputation cause, surgical level; P<0.05) explained the variance in 2MWT (adjusted R2=0.685). Patient-reported and performance-based modifiable factors (Houghton score, 2MWT; P<0.001) explained PEQ-MS variance (adjusted R2=0.660). Integumentary (P=0.022) and cardiopulmonary (P<0.001) comorbidities explained an additional 4% of PEQ-MS variance, while surgical level was insignificant. CONCLUSIONS: Both modifiable and non-modifiable factors explained prosthetic functional mobility. Performance-based walking was explained by modifiable factors including balance ability and confidence, prosthesis and walking aid use. Patient-reported function was also explained by prosthesis and walking aid use, walking speed and medical comorbidities. Modifiable factors for objective and subjective prosthetic mobility may provide a clinical roadmap for rehabilitation.

Accuracy and precision of consumer-level activity monitors for stroke detection during wheelchair propulsion and arm ergometry.

The purpose of this study was to evaluate whether consumer-level activity trackers can estimate wheelchair strokes and arm ergometer revolutions. Thirty able-bodied participants wore three consumer-level activity trackers (Garmin VivoFit, FitBit Flex, and Jawbone UP24) on the wrist. Participants propelled a wheelchair at fixed frequencies (30, 45 and 60 strokes per minute (spm)) three minutes each and at pre-determined varied frequencies, (30-80 spm) for two minutes. Participants also freely wheeled through an obstacle course. 10 other participants performed arm-ergometry at 40, 60 and 80 revolutions per minute (rpm), for three minutes each. Mean percentage error (MPE(SD)) for 30 spm were ≥46(26)% for all monitors, and declined to 3-6(2-7)% at 60 spm. For the obstacle course, MPE ranged from 12-17(7-13)% for all trackers. For arm-ergometry, MPE was at 1-96(0-37)% with the best measurement for the Fitbit at 60 and 80 rpm, and the Garmin at 80rpm, with MPE = 1(0-1)%. The consumer-level wrist-worn activity trackers we tested have higher accuracy/precision at higher movement frequencies but perform poorly at lower frequencies.
