[Long-term effects of an assets-based, co-created physical activity intervention on health-related quality of life in older adults]. / Efectos a largo plazo de un programa de actividad física enriquecido en la calidad de vida relacionada con la salud en adultos mayores.

PURPOSE: The purpose of this study is to examine the long-term effects of a programme called Ser Mayor, un RETO («Being Older, a Challenge¼) aimed at improving quality of life in older adults over 60 living in the community. METHODS: This programme used co-design principles to create sustainable opportunities to improve quality of life, connecting with the community, and empowering older adults to take responsibility for their own health. Ser Mayor, un RETO was based on Bronfenbrenner's bio-social-ecological perspective and the health assets model. Its design was complemented with leisure education and physical activity promotion-based guidelines, identified in the scientific literature. The study design was quasi-experimental, with control group, and was conducted over a period of 20-months (September 2017 to June 2019) in several municipalities near the city of Zaragoza (Spain), with the participation of 213 older adults (n=120 experimental group and n=93 control group). Data were analysed using generalised linear mixed models controlling for age and gender of participants and accounting for initial differences between groups in the study outcomes. RESULTS: The results indicate that the experimental group experienced an improvement in levels of quality of life relative to the control group, which was sustained over the study period, especially in several physical dimensions of quality of life: physical function (P=.014), physical role (P=.027), physical component summary (P=.022) and in emotional role (P=.033). CONCLUSION: The Ser Mayor, un RETO programme had a positive effect on the quality of life of older adults, showing potential for sustainability of its effects and for the service providers to develop a sense of ownership over the programme.

Enhancing efficiency and quality control: The impact of Digital Twins in drinking water networks.

This paper showcases the successful development and implementation of two Digital Twin prototypes within the Lab Digital Twins project, designed to enhance the efficiency and quality control of Aigües de Barcelona's drinking water network. The first prototype focuses on asset management, using (near) real-time data and statistical models, and achieving a 70% success rate in predicting pump station failures 137 days in advance. The second prototype addresses water quality monitoring, leveraging machine learning to accurately forecast trihalomethane levels at key points in the distribution system, and enabling proactive water quality management strategies, ensuring compliance with stringent safety standards and safeguarding public health. The paper details the methodology of both prototypes, highlighting their potential to revolutionize water network management. PRACTITIONER POINTS: Digital representation of assets and processes in the drinking water treatment network Early fault detection in assets, and predictions of trihalomethane formation in the drinking water distribution network Reduction on monitoring time and incident response for target assets by means of Digital Twins Improvement in visualization, prediction, and proactive measures for asset management and water quality control Contribution to the growing knowledge on Digital Twins and their potential to revolutionize water network operations.

Asset Framing: a Tool for Enhanced Equity in Feedback and Assessment.

Asset framing can enhance equity in feedback and assessment in medical education. It is said that what you find depends on how you see, and the narratives that we build in our minds can influence our judgement and our assessments when working with learners. Asset framing has been used in other fields, and found to be an effective tool to reduce bias and enhance equity. In our article, we discuss biases that may occur in assessment and feedback, and how asset framing can be an effective tool to help mitigate this. We propose solutions at individual, departmental, and institutional levels.

Personal Finance: Basic Instruments, Taxation Strategies, & Unique Opportunities.

The authors provide a simple primer for hand surgeons to further educate themselves on the basics of investing, tax reduction strategies that are completely legal, insurance protection, especially in your formative years, and unusual options available for further consideration. There are many ways for further education including publications related to finance, investment clubs of like-minded individuals, mentors that have extensive experience in these areas, and formal courses sponsored by business schools or other venues. The opportunities and regulatory environment are ever-changing, so one needs to constantly keep up with taxation rules and newer investment options.

Transforming Health Care Delivery: Innovations in Payment Models for Interprofessional Team-Based Care.

By examining the strengths, limitations, and implications of different payment models we seek to inform policymakers, practitioners, and educators on the path toward patient-cen-tered, efficient, and sustainable primary health care deliv-ery. Health care payment model reform should be viewed as an investment in future health asset capacity and equity production rather than an immediate return on investment for short-term health care cost reduction.

An 'alcohol health champions' intervention to reduce alcohol harm in local communities: a mixed-methods evaluation of a natural experiment.

Background: Globally alcohol consumption is a leading risk factor for premature death and disability and is associated with crime, social and economic consequences. Local communities may be able to play a role in addressing alcohol-related issues in their area. Objectives: To evaluate the effectiveness and cost-benefit of an asset-based community development approach to reducing alcohol-related harm and understand the context and factors that enable or hinder its implementation. Design: A mixed-methods evaluation. Area-level quasi-experimental trial analysed using four different evaluation methods (a stepped-wedge design where each area was a control until it entered the intervention, comparison to matched local/national controls and comparison to synthetic controls), alongside process and economic evaluations. Setting: Ten local authorities in Greater Manchester, England. Participants: The outcomes evaluation was analysed at an area level. Ninety-three lay persons representing nineareas completed questionnaires, with 12 follow-up interviews in five areas; 20 stakeholders representing ten areas were interviewed at baseline, with 17 follow-up interviews in eight areas and 26 members of the public from two areas attended focus groups. Interventions: Professionals in a co-ordinator role recruited and supported lay volunteers who were trained to become alcohol health champions. The champion's role was to provide informal, brief alcohol advice to the local population and take action to strengthen restrictions on alcohol availability. Main outcome measures: Numbers of alcohol-related hospital admissions, accident and emergency attendances, ambulance call-outs, street-level crime and antisocial behaviour in the intervention areas (area size: 1600-5500 residents). Set-up and running costs were collected alongside process evaluation data exploring barriers and facilitators. Data sources: Routinely collected quantitative data on outcome measures aggregated at the intervention area and matched control and synthetic control areas. Data from policy documents, licensing registers, meeting notes, invoices, time/cost diaries, training registers, questionnaires, interviews, reflective diaries and focus groups. Results: The intervention rolled out in nine out of ten areas, seven of which ran for a full 12 months. Areas with better-established infrastructure at baseline were able to train more champions. In total, 123 alcohol health champions were trained (95 lay volunteers and 28 professionals): lay volunteers self-reported positive impact. Champions engaged in brief advice conversations more readily than taking action on alcohol availability. There were no consistent differences in the health and crime area-level indicators between intervention areas and controls, as confirmed by using three different analysis methods for evaluating natural experiments. The intervention was not found to be cost-beneficial. Limitations: Although the sequential roll-out order of the intervention was randomised, the selection of the intervention areas was not. Self-reported impact may have been subject to social desirability bias due to the project's high profile. Conclusions: There was no measurable impact on health and crime outcomes. Possible explanations include too few volunteers trained, volunteers being unwilling to get involved in licensing decisions, or that the intervention has no direct impact on the selected outcomes. Future work: Future similar interventions should use a coproduced community outcomes framework. Other natural experiment evaluations should use methodological triangulation to strengthen inferences about effectiveness. Trial registration: This trial is registered as ISRCTN81942890. Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Public Health Research programme (NIHR award ref: 15/129/03) and is published in full in Public Health Research; Vol. 12, No. 9.

Alcohol consumption puts an individual's health and social relationships at risk of harm. The more a person drinks, the more harmful it is. The harmful effects can place a burden on emergency services and hospitals. We wanted to find out whether community members can make a difference by taking action to address alcohol harm in their local area. Local councils in Greater Manchester developed a project called Communities in Charge of Alcohol, where volunteers in targeted local areas were trained to become 'alcohol health champions'. Alcohol health champions gave alcohol-related brief advice to people to help them drink less. They had a say about when, where and how alcohol is sold by reporting issues to their local council. We compared numbers of alcohol-related hospital admissions, accident and emergency attendances, ambulance call-outs and reports of crime and antisocial behaviour between areas that had alcohol health champions with other similar areas in England that did not. We calculated how much it costs to run and whether Communities in Charge of Alcohol could save society money. Not as many volunteers came forward to become an alcohol health champion as hoped for. Those who did give alcohol-related brief advice to people. They preferred not to report issues about alcohol sales to their local council, either because it was too complicated or because they did not want to be called a 'grass'. We did not find levels of alcohol harm changed in the Communities in Charge of Alcohol areas. Because of this, we could not demonstrate that Communities in Charge of Alcohol could save society money. Getting involved in alcohol licensing decisions needs to be made easier for communities, with more anonymity, through the support of professionals. More work needs to be done to understand whether giving brief advice can reduce alcohol harm in whole communities.

Assessing coastal population capacity in Tsunami-prone areas: A grid-based approach.

Tambakrejo Beach in Blitar Regency is classified as an area that is very vulnerable to tsunami catastrophes. Many researchers have conducted studies on regions impacted by the tsunami. However, more studies into the link between the outcomes of social and spatial studies still need to be carried out because these are two different perspectives with different parameters and variables. The novel approach in this research involves delineating tsunami-affected areas and assessing population capacity in coastal regions. The hazard maps and livelihood asset variables using grid cells of a specific size have been used to identify risk levels. The grid cells used are 50 m2 × 50 m² so that they are expected to represent the minor units on the face of the earth, such as buildings, assets, property or land parcels, for capacity assessments or measuring the level of threat to disasters and are no longer based on regional administrative boundaries. Contribution: The research results show that using grid cells to analyse areas affected by the tsunami can provide excellent and informative results. Research findings at the research location regarding community preparedness in facing tsunamis show that communities at risk of being affected by the tsunami need to increase their capacity because the majority of communities in coastal areas, especially in the Sidorejo sub-village, have been identified as having low capacity according to several livelihood asset parameters such as financial capital in income. By increasing individual capacity, it is hoped that society will be able to avoid the threat of tsunami waves better.

Transitioning Toward a Zero-Emission Electricity Sector in a Net-Zero Pathway for Africa Delivers Contrasting Energy, Economic and Sustainability Synergies Across the Region.

Although Africa contributes less than 5% to global greenhouse gas (GHG) emissions, its role in global climate action is pivotal. To date, 53 African countries have submitted their Nationally Determined Contributions (NDCs), and four have committed to a net-zero target. However, many of Africa's NDCs are vaguely expressed and without specific focus on explicit sectoral decarbonization targets. Furthermore, Africa's huge land-based carbon dioxide removal (CDR) potential remains unclear in the context of enabling net-zero (NZ) emissions within the continent. This study achieves two objectives: Under a NZ GHG emission trajectory in Africa, we uncover the implications of a targeted zero-emission electricity sector by 2030, on the energy landscape and other sustainability factors. This study also features the role of land-based biological removal methods─bioenergy carbon capture and storage (BECCS) and afforestation/reforestation (A/R)─in net zero actualization in Africa. Our results reveal a unified but disparate actualisation of the mid-century net zero emission goal across the continent, as all regions except North Africa achieve carbon neutrality. The industrial sector faces significant difficulties in transitioning and contributes substantially to positive emissions on the continent, with its share of total residual emissions reaching 49-64% by 2050. This difficulty persists even with targeted sectoral decarbonization of the electricity sector, although it is significantly reduced by the availability of BECCS as a CDR option. Under the zero-emission electricity pathway, emissions in buildings and transport sectors are reduced due to rapid electrification. A trade-off emerges in the net zero pathway concerning land allocation for negative emissions versus other land use activities. A key result shows that achieving a net zero target in Africa leads to a cumulative loss of $102 billion in fossil fuel infrastructure within the electricity sector by mid-century, which doubles when the zero-emission electricity goal is achieved.

Evaluation of the value of Internet platform Enterprises in the digital economy by the big data cooperation asset valuation model.

With the innovation of information technology, the national industry has been adjusted and upgraded, and the development of the Internet industry has had a huge impact on economic development. The investment and financing of network enterprises and the merger and acquisition of network companies need to evaluate the value of network companies. In this regard, this paper evaluated the value of Internet platform enterprises under the digital economy based on the Big Data (BD) cooperation asset valuation model. This paper analyzed the factors affecting the value evaluation of Internet enterprises and discussed the advantages of BD cooperative asset valuation model in the value evaluation of Internet enterprises in the digital economy. The BD cooperation asset valuation model was constructed, and the value evaluation experiment of Internet platform enterprises under the digital economy was carried out. The experimental results of this paper showed that in the evaluation of the profitability value of Internet enterprises, the difference between the net sales interest rate was 0.14%-0.51 %. The difference between the net interest rate of equity was 0.09%-0.67 %, and the difference between the net interest rate of total assets was 0.19%-0.92 %; in terms of the evaluation of the operating capacity of Internet enterprises, the difference between the current asset turnover rate was 0.05-0.16. The difference of non-current asset turnover rate was 0.02-0.15, and the difference of total asset turnover rate was 0.01-0.16. The evaluation value based on the BD cooperation asset valuation model was not different from the actual enterprise value, which showed that the BD cooperation asset valuation model had good advantages in the evaluation of the value of Internet enterprises.

Research on the impact and heterogeneity of housing on the allocation of financial assets of households: Evidence from China.

This paper investigates the impact of housing with both consumption and investment attributes on the risky financial asset allocation of households, constructs Probit and Tobit models using 2019 China Household Finance Survey (CHFS) data, and proceeds to the mediation effect test and heterogeneity analysis. Results indicate that owning only one house exhibits a crowding-out effect on the risky financial asset allocation of urban households, with the degree of risk preference as the mediating effect mechanism, while owning multiple houses exhibits an asset allocation effect. Housing borrowing other than bank loans inhibits urban households from making risky financial asset allocations. The effect of housing on risky financial asset allocation is heterogeneous by income, age, and region.

Excluding livestock access to farm dams reduces methane emissions and boosts water quality.

Farm dams, also known as 'agricultural ponds', are ubiquitous features of agricultural landscapes globally. Those accessed by livestock have high methane (CH4) emissions per unit area relative to other freshwater systems. Fencing dams and installing water troughs to prevent livestock from entering the dams are promising strategies to improve water quality and substantially reduce their carbon footprints. However, previous studies only measured the effects of fencing on methane diffusive emissions without considering ebullitive fluxes (i.e., methane bubbles), which is often the dominant emission pathway in smaller water bodies. Also, data is lacking on how the benefits of fencing farm dams vary across seasons. Using Australia as a test case, this study investigates the benefit of fencing off farm dams by monitoring total CH4 (diffusion + ebullition) and carbon dioxide (CO2) in summer and winter. Fenced dams had 72 % lower CH4 emissions in summer and 92 % lower in winter than unfenced dams. Similarly, CO2-equivalent (CO2 + CH4) fluxes were lower in fenced dams by 59 % in summer and 73 % in winter. Fenced dams had higher water quality, with 51 % less total dissolved nitrogen, 57 % less phosphorous, and 23-49 % more dissolved oxygen. Average daily air temperature was a key predictor of CH4 emissions from farm dams, underscoring the importance of considering temporal dynamics for estimating yearly farm dam emissions. We confirmed that excluding livestock from entering farm dams using fences significantly mitigates CH4 emissions and enhances water quality, and these benefits are maintained seasonally.

A Citizen Science and Photovoice Approach to Food Asset Mapping and Food System Planning.

Food asset mapping conducted by planners and policymakers usually consists of an online map identifying the locations of food-related sites in cities. However, food asset mapping may be limited in its consideration for ecological and cultural assets critical for community food security. Furthermore, what are considered "assets" may not reflect the everyday lived experiences of marginalized communities. This study applied a "citizen science" photovoice food asset mapping involving diverse participants in the City of Vancouver. In applying a citizen science photovoice approach, this study surfaced "hidden" contexts, food assets, and stories to integrate diverse community perspectives in food system planning.

El mapeo de activos alimentarios realizado por planificadores y formuladores de políticas generalmente consiste en un mapa en línea que identifica las ubicaciones de los sitios relacionados con los alimentos en las ciudades. Sin embargo, el mapeo de activos alimentarios puede estar limitado en su consideración de activos ecológicos y culturales críticos para la seguridad alimentaria de la comunidad. Además, lo que se considera "activos" puede no reflejar las experiencias cotidianas de las comunidades marginadas. Este estudio aplicó un mapeo de activos de alimentos de fotovoz de "ciencia ciudadana" que involucró a diversos participantes en la ciudad de Vancouver. Al aplicar un enfoque de fotovoz de ciencia ciudadana, este estudio reveló contextos "ocultos," activos alimentarios y historias para integrar diversas perspectivas comunitarias en la planificación del sistema alimentario.

BIM-enabled built-asset information management conceptual framework: A case of public university buildings in Addis Ababa, Ethiopia.

The integration of BIM with other digital advancements has demonstrably led to an increase of performance in the Architecture, Engineering, Construction and Operation (AECO) industry. This integration not only is showing promising results in boosting the industry's performance, but also the productivity and promotes data-driven decision-making. Despite these benefits, there are limited studies that address the integration of BIM and digital data for managing built-assets in general and in developing countries in particular. To fill this gap, a closer assessment of current built-asset information management practice is necessary. The assessment of the practice examines how digital processes and/or technology can be seamlessly integrated into existing practices. In this regard, this study aims to provide valuable insights into increasing the maturity of built-asset information management by integrating digital data with BIM. The study uses a case-based research design using built-assets (universities in Addis Ababa) as public building representative to capture the prevailing information management practices in Ethiopian public buildings. The findings reveal that traditional paper-based practices still dominate the management of built-assets. This leads to difficulties in terms of data loss, unavailability, inaccuracy, and unreliability, all of which are detrimental to the overall performance. Based on these findings, a conceptual framework is designed to improve the performance of built-assets and help owners, end-users, and managers in defining data and information requirements for BIM-enabled asset information management. The framework delineates processes for structured information requirements definition and validation of various asset data from varying sources. The framework utilizes a BIM-enabled platform as a single source of truth and offers a comprehensive solution to the identified challenges. The findings of this study holds significant promise for improving the existing practice of built-asset information management within the study context.

Metrics to quantify the degree of co-location of urban water infrastructure.

Co-located infrastructure networks such as road, water, and sewer in theory offer the possibility for integrated multi-infrastructure interventions. However, how closely these networks are aligned in space and time determines the practical extent to which such coordinated interventions can be realized. This study quantifies the spatial alignment of the aforementioned infrastructure networks and demonstrates its application for integrated interventions and potential cost savings. It proposes two metrics, namely 1) shared surface area and, 2) shared trench volume, to quantify the spatial relationship (i.e., degree of co-location) of infrastructures. Furthermore, the study demonstrates how the degree of co-location can be used as a proxy for cost-saving potential of integrated interventions compared to silo-based, single-infrastructure, interventions. Through six case studies conducted in Norwegian municipalities, the research reveals that implementing integrated interventions across road, water, and sewer networks can result in potential average cost savings of 24% in urban areas and 11% in rural areas. Utility-specific savings under different cost-sharing scenarios were also analysed. To identify the yearly potential of integrated multi-infrastructure interventions, future work should add the temporal alignment of rehabilitation of infrastructures (i.e., time of intervention need for the infrastructures).

Publicly Available Anatomic Total Shoulder Arthroplasty Rehabilitation Protocols Show High Variability and Frequent Divergence from the 2020 ASSET Recommendations.

Background: In 2020, the American Society of Shoulder and Elbow Therapists (ASSET) published an evidence-based consensus statement outlining postoperative rehabilitation guidelines following anatomic total shoulder arthroplasty (TSA). Purpose: The purpose of this study was to (1) quantify the variability in online anatomic TSA rehabilitation protocols, and (2) assess their congruence with the ASSET consensus guidelines. Methods: This study was a cross-sectional investigation of publicly available, online rehabilitation protocols for anatomic TSA. A web-based search was conducted in April 2022 of publicly available rehabilitation protocols for TSA. Each collected protocol was independently reviewed by two authors to identify recommendations regarding immobilization, initiation, and progression of passive (PROM) and active range of motion (AROM), as well as the initiation and progression of strengthening and post-operative exercises and activities. The time to initiation of various components of rehabilitation was recorded as the time at which the activity or motion threshold was permitted by the protocol. Comparisons between ASSET start dates and mean start dates from included protocols were performed. Results: Of the 191 academic institutions included, 46 (24.08%) had publicly available protocols online, and a total of 91 unique protocols were included in the final analysis. There were large variations seen among included protocols for the duration and type of immobilization post-operatively, as well as for the initiation of early stretching, PROM, AROM, resistance exercises, and return to sport. Of the 37 recommendations reported by both the ASSET and included protocols, 31 (83.78%) were found to be significantly different between groups (p\<0.05). Conclusion: Considerable variability was found among online post-operative protocols for TSA with substantial deviation from the ASSET guidelines. These findings highlight the lack of standardization in rehabilitation protocols following anatomic TSA. Level of Evidence: 3b.

Reliability and validity of the Japanese version of the Survey of Perceived Organizational Support.

OBJECTIVES: This study aimed to examine the reliability and validity of the Japanese version of the Survey of Perceived Organizational Support (SPOS-J) for the Japanese workforce. METHODS: The translation of the SPOS into Japanese followed the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Task Force guidelines. An online baseline survey with 6220 Japanese workers assessed the SPOS-J and related scales, followed by a follow-up survey with 452 respondents 2 weeks later. We developed the SPOS-J and evaluated its factorial, convergent, and known-group validities, as well as its internal consistency, test-retest reliability, and interpretability. RESULTS: Exploratory and confirmatory factor analysis (EFA and CFA) indicated that the SPOS-J, diverging from the original version's 1-factor structure, adopted a 2-factor structure comprising 2 subscales: the SPOS-J (Sufficiency of Positive Aspects [SPA]) and the SPOS-J (Minimality of Negative Aspects [MNA]). The final version of the SPOS-J, consisting of 8 items selected by the item response theory analysis, demonstrated acceptable model fit in the CFA. Cronbach a values for SPOS-J (SPA) and SPOS-J (MNA) were .92 and .84; intraclass coefficients were 0.72 and 0.55, respectively. The correlations between SPOS-J (SPA) and related variables, as well as the score distributions by demographic characteristics, supported the convergent and known-group validity of SPOS-J (SPA). In contrast, SPOS-J (MNA) showed lower correlation coefficients with all related variables and supported known-group validity. CONCLUSIONS: The SPOS-J (SPA), a subscale of the 8-item SPOS-J, is a reliable and valid measure for assessing perceived organizational support among Japanese workers.

Financial Well-Being for Thoracic Surgeons.

The authors provide a brief overview for thoracic surgeons in topics essential to achieving financial well-being as a student, trainee, practicing surgeon, and beyond. While broad in nature, the authors' article is comprehensive, and they cover topics including student loans, asset and wealth management, investment opportunities, financial and estate planning, and insurances. It is hoped that the information provided will allow thoracic surgeons to become more familiar with the financial topics that pertain to thoracic surgeons and provide an introduction to explore financial wellness and literacy more thoroughly.

Nurturing care assets for food security: a community asset mapping approach.

BACKGROUND: Zip codes classified by the Food Insecurity Index with moderate and high food insecurity (FI) risk can be a threat to the health and well-being of children during the first 1,000 days (from pregnancy to 2 years). The presence of nurturing care assets (i.e., stable environments that promote health and nutrition, learning opportunities, security and safety, and responsive relationships) can contribute to supporting families and their communities, and ultimately reduce systemic barriers to food security. We aimed to identify and characterize nurturing care assets in under-resourced communities with moderate and high FI risk. METHODS: Four steps were used to conduct a Community Asset Mapping (CAM): (1) review of community documents across five zip codes in Clark County, Nevada (2), engagement of community members in identifying community assets (3), definition of the assets providing nurturing care services, and (4) classification of assets to nurturing care components, i.e., good health, adequate nutrition, safety and security, opportunities for early learning, and responsive caregiving. The Food Insecurity Index was used to determine FI risk in each zip code. Analyses explored whether disparities in nurturing care assets across zip codes with moderate and high FI exist. RESULTS: We identified 353 nurturing care assets across zip codes. A more significant number of nurturing care assets were present in zip codes with high FI risk. The adequate nutrition component had the most assets overall (n = 218, 61.8%), while the responsive caregiving category had the least (n = 26, 7.4%). Most of the adequate nutrition resources consisted of convenience stores (n = 96), food pantries (n = 33), and grocery stores (n = 33). Disparities in the number and type of good health, early learning, and security and safety assets were identified within zip codes with high FI risk compared to moderate FI risk. CONCLUSIONS: The quantity and type of nurturing care assets can exacerbate existing demographic disparities across zip codes, which are tied to barriers to access to food in under-resourced communities in Clark County, Nevada. Co-creating a nurturing care asset-based zip code strategy to address high FI risk will require strengthening systems across existing nurturing care assets.

Policy analysis for informing climate adaptation, environmental resilience, and irrigation demands in the Rio Grande Basin.

Water policymakers internationally face the challenge of adapting to climate, supporting environmental resource needs, and meeting irrigation demands for food security in the world's arid and semi-arid regions. Much recent work has assessed the economic performance of environmental river flows to support endangered species habitat protection. However, little published work to date has systematically formulated and applied methods to identify the economic performance of various policy measures that adapt to climate, support endangered species, and meet irrigation demands for water. This work's original contribution with international relevance is to address those gaps by identifying the economic performance of various water shortage sharing methods for handling climate water stress while supporting protection of critical habitat to protect the endangered Southwestern willow flycatcher (Empidonax traillii extimus) along with Willow tree (Salix bonplandiana) habitat in the middle part of the Rio Grande Basin in North America, a region facing a number of conflicts between commercial uses of water and protection of key ecological assets. It develops a hydroeconomic optimization model containing information on crop water use and endangered species requirements in that region to identify the economic performance of three climate adaptation policy scenarios for handling water shortages while respecting endangered species habitat protection requirements. Results show how water shortages as well as policy responses for handing those shortages affect the economic value of water in agriculture for food security both with and without critical habitat to support the endangered flycatcher. This work's international relevance comes from its capacity to inform policy debates on the costs of protecting endangered species habitat under various climate scenarios and climate policy adaptation measures. Findings provide a general framework to address existing gaps in understanding and measuring the economic performance of measures to promote environmental resilience.

A deep dive into green infrastructure failures using fault tree analysis.

Green Infrastructure has transformed traditional urban stormwater management systems by fostering a wide range of service functions. Despite their popularity, green infrastructure's performance can deteriorate over their lifecycle, leading to operational failures. The operation of green infrastructure has predominantly relied on reactive maintenance strategies. To anticipate malfunctions and enhance the performance of green infrastructure in the long run, failure data needs to be recorded so that deterioration processes and component vulnerabilities can be recognized, modelled and included in predictive maintenance schemes. This study investigates possible failures in representative GIs and provides insights into the most important events that should be prioritized in the data collection process. A method for qualitative Fault Tree Analysis using minimal cut sets are introduced, aiming to identify potential failures with the minimum number of events. To identify events of interest fault trees were constructed for bioswales, rain gardens and green roofs, for three groups of service function failures, namely runoff quantity control, runoff quality control and additional service functions. The resulting fault trees consisted of 45 intermediate and 54 basic events. The minimal cut set analysis identified recurring basic events that could affect operation among all three green infrastructure instances. These events are 'trash accumulation', 'clogging due to sediment accumulation', and 'overly dense vegetation'. Among all the possible cut sets, events such as 'plants not thriving', 'invasive plants taking over', and 'deterioration caused by external influences' could potentially disrupt most of the service functions green infrastructure provides. Furthermore, the analysis of interactions between component failures shows vegetation and filter media layer failures have the highest influence over other components. The constructed fault trees and identified basic events could be potentially employed for additional research on data collection processes and calculating the failure rates of green infrastructure and as a result, contribute to a shift toward their proactive operation and maintenance.
