- Description: Forensic mental health nurses (FMHN) provide care to address the needs of people who have mental illnesses across a range of diverse settings. The Clinical Reasoning Cycle (CRC) has been identified as a potential framework to assist FMHNs; however, adaptations were required to reflect the unique nature of the clinical setting. This study aimed to explore adaptations made to determine suitability prior to implementation in practice. Nominal Group Technique was used to explore suggested adaptations determined from a previous study and reach a consensus on the changes. Fourteen senior nurses from a state-wide Forensic mental Health (FMH) service participated. A consensus was reached for two proposed changes. Data were analysed using thematic analysis. Three main themes were interpreted from the data; FMH adaptations are warranted, the focus of the CRC, and who owns the cycle? Nurses in this study considered the need to include offence and risk issues due to the impact these factors have on the therapeutic relationship and cognitive bias; however, they also identified the need to focus on recovery-oriented care while engaging in clinical reasoning. Nurses in this study also expressed some reluctance for nursing to ‘own' the model, due to concern that ownership may cause division among the team or result in inconsistency in care. However, some participant's suggested the CRC with adaptations assisted FMH nurses to articulate their specialist skills and knowledge to others and highlight the nursing contribution to care. Further work is needed to finalize adaptations with a focus on engaging the consumer carer workforce and interdisciplinary team. © 2022 The Authors.

- Description: The city of Christchurch, New Zealand, incurred significant damage due to a series of earthquakes in 2010 and 2011. The city had, by the late 2010s, regained economic and social normalcy after a sustained period of rebuilding and economic recovery. Through the concerted rebuilding effort, a modern central business district (CBD) with redesigned infrastructure and amenities was developed. The Christchurch rebuild was underpinned by a commitment of urban planners to an open and connected city, including the use of innovative technologies to gather, use and share data. As was the case elsewhere, the COVID-19 pandemic brought about significant disruptions to social and economic life in Christchurch. Border closures, lockdowns, trading limitations and other restrictions on movement led to changes in traditional consumer behaviors and affected the retail sector’s resilience. In this study, we used CBD pedestrian traffic data gathered from various locations to predict changes in retail spending and identify recovery implications through the lens of retail resilience. We found that the COVID-19 pandemic and its related lockdowns have driven a substantive change in the behavioral patterns of city users. The implications for resilient retail, sustainable policy and further research are explored.

- Description: Restoration of native grasslands is challenging due to high soil phosphorus levels. Cultivation of plants with high phosphorus (P) absorption is an optimal solution to remove and decrease P from the soil. It has been demonstrated that native grassland taxa (species) of the genus Ptilotus have significant P-uptake. In a glasshouse study, Ptilotus macrocephalus and Ptilotus polystachyus were tested for their ability to reduce the amount of soil phosphorus that was readily available. Lupinus albus, a third species with a reputation for high phosphorus uptake, served as a comparison species, and a further treatment included Phoslock®, a soil additive that could bind soil phosphorus into insoluble forms. The findings revealed that phosphorus in the soil was absorbed at a high level via Ptilotus macrocephalus and Ptilotus polystachyus showed a maximum reduction of P (-2.58 and -2.55 ppm). It is argued that several years of planting and harvesting these plants will offer a workable method for lowering soil phosphorus levels. However, this only happened at high concentrations of 1500 g/m2 and when soil phosphorus concentrations were very high. Despite, the Phoslock®'s effectiveness in lowering soil-accessible phosphorus. At concentrations often observed in former agriculture paddocks, it proved less effective. The study's findings have improved our existing comprehension of reclaiming abandoned grassland. © 2023 Authors. All rights reserved.

- Description: With the internationalisation of higher education, students from culturally and linguistically diverse (CALD) backgrounds represent a significant proportion of the university student body in Australia. Research literature indicates that the unique cultural and linguistic challenges experienced by these students may adversely impact their academic performance and social integration in university settings. However, less is known about how the socio-emotional competencies of undergraduate CALD and non-CALD domestic English-speaking students compare. This cross-sectional quantitative study compares the emotional and social competencies in a cohort of CALD and non-CALD occupational therapy undergraduates. Data were collected at one Australian university from a group of 360 students enrolled in the Bachelor of Occupational Therapy (Honours) course. Participants completed the Emotional and Social Competency Inventory– University edition (ESCI-U). Multivariate regression analyses were used to compare between CALD and non-CALD students, controlling for students’ year level of study, age, and gender. Key findings from the regression analysis included the observation of indicate that non-CALD students having significant higher scores than CALD students on all the ESCI-U socio-emotional subscales, especially the Emotional Self-control, Achievement Orientation, Empathy and Teamwork from western perspectives. No difference was found between CALD and non-CALD student on two cognitive competencies- systems thinking and pattern recognition. These findings should be interpreted with caution considering CALD students may interpret the questions differently and demonstrate the competencies in different ways. Specific emotional and social competencies that need to be strengthened in students are discussed and recommendations are made to inform the preparation of evidence-based curricula.

- Description: Patient falls in hospital may lead to physical, psychological, social and financial impacts. Understanding patients’ perceptions of their fall risk will help to direct fall prevention strategies and understand patient behaviours. The aim of this study was to explore the perceptions and experiences that influence a patient’s understanding of their fall risk in regional Australian hospitals. Semi-structured, individual interviews were conducted in wards across three Australian hospitals. Participants were aged 40 years and over, able to communicate in English and were mobile prior to hospital admission. Participants were excluded from the study if they returned a Standardised Mini-Mental State Examination (SMMSE) score of less than 18 when assessed by the researcher. A total of 18 participants with an average age of 69.8 years (SD ± 12.7, range 41 to 84 years) from three regional Victorian hospitals were interviewed for this study. Data were analysed using a reflexive thematic analysis identifying three major themes; (1) Environment (extrinsic) (2) Individual (intrinsic), and (3) Outcomes, as well as eight minor themes. Participants recognised the hazardous nature of a hospital and their personal responsibilities in staying safe. Falls education needs to be consistently delivered, with the focus on empowering the patient to help them adjust to changes in their clinical condition, whether temporary or permanent. © 2022 by the authors.

- Description: Background Various brain stimulation devices capable of generating high-frequency currents are readily available. However, our comprehension of the potential side or therapeutic effects associated with high-frequency transcranial pulsed current stimulation (tPCS), particularly concerning the new 400 Hz tPCS device, AscenZ-IV Stimulator, developed by AscenZion Neuromodulation Co. Pte. Ltd. in Singapore, remains incomplete. Objective This study examines preliminary parameters for the safe and comfortable application of 400 Hz tPCS at intensities below 2 mA. Methods In a cross-sectional study, 45 healthy participants underwent sub-2 mA 400 Hz tPCS to assess sensory, motor, and pain thresholds on the dominant side. Study 1 (N = 15) targeted the primary motor cortex of the right-hand area, while study 2 (N = 30) focused on the back of the right forearm. Results Study one showed that increasing the current intensity gradually resulted in no responses at sub-0.3 mA levels, but higher intensities (p < 0.001) induced sensory perception and pain responses. Study two replicated these findings and additionally induced motor responses along with the sensory and pain responses. Conclusion Despite the theoretical classification of tPCS as a subsensory level of stimulation, and the expectation that individuals receiving this type of current should not typically feel its application on the body, this high-frequency tPCS device generates different levels of stimulation due to the physiological phenomenon known as temporal summation. These novel levels of stimulation could be viewed as either potential “side-effects” of high frequency tPCS or as additional “therapeutic benefits”. This dual capacity may position the device as one that generates both neuromodulatory and neurostimulatory currents. Comprehensive comprehension of this is vital for the development of therapeutic protocols that incorporate high-frequency tPCS. Copyright: © 2023 Jaberzadeh, Zoghi.

- Description: Cancer is a prevalent disease with significant morbidity and mortality rates. Exercise interventions implemented before, during, or after cancer-based surgeries have shown promising benefits in improving fitness, postoperative complications, and quality of life. This thesis comprises three original research chapters aimed at investigating the effect of perioperative and preoperative 'prehabilitation' exercise in breast, colorectal, and prostate cancer patients. The first study focused on exploring exercise therapy interventions and their impact on cardio-respiratory fitness and 30-day postoperative outcomes in colorectal cancer patients. The systematic review and meta-analysis (N= 411 intervention and N= 368 control) revealed a small but significant improvement in cardio-respiratory fitness (SMD = 0.18; 95% CI = 0.03, 0.32; p < 0.05) with exercise interventions, although no significant impact on 30-day postoperative outcomes was observed. In the second study, various exercise types, including aerobic, resistance, flexibility, and mind-body exercises (alone or in combination), were compared in terms of their effect on cardio-respiratory fitness and 30-day postoperative outcomes in colorectal cancer patients (N= 411 intervention and N= 368 control). The network meta-analysis findings indicated that engaging in aerobic exercise alone (SMD = 0.30) or a combination of aerobic, resistance, and flexibility exercises (SMD = 0.57) yielded the most significant improvements in cardio-respiratory fitness. The final study examined the efficacy of pre-surgical aerobic exercise (prehabilitation) therapy in relation to post-operative cardio-respiratory fitness, quality of life, and 30-day postoperative outcomes in the Grampians Region of Victoria. The prehabilitation (PREHAB) group included a supervised aerobic based program which would see patients exercise every two/three days for a minimum of 2 weeks. A total of 11 PREHAB and 9 usual care (UCARE) patients were enrolled and analysed. The study showed that a prehabilitation exercise program resulted in small clinical improvements in some markers of cardio-respiratory fitness (+1.5% and +1.2% for absolute and relative V̇O2peak, respectively) and is safe and feasible. However, no significant improvements were observed in quality of life and 30-day postoperative outcomes. While the overall findings demonstrate some positive effects of perioperative and specifically prehabilitation exercise, it is important to consider the magnitude of these effects and any specific factors contributing to their success, if applicable. Further research is needed to fully understand the potential benefits and limitations of exercise before, during and after surgery in this patient population.

- Description: Forensic mental health (FMH) inpatient settings are complex working environments at times due to a number of factors including the presence of challenging behaviours that may include violence and aggression, restrictions related to legislation, extended length of stay and the impact of trauma. Nurse unit managers (NUMs) play an important role in managing the unit environment and clinical standards of care to achieve better outcomes for consumers and staff. However, the role of NUMs in an FMH setting is poorly understood. The overall aim of this study was to explore the role of NUMs working within an FMH setting in Victoria, Australia. To our knowledge, this is the first study that has examined the subject. Data were collected via focus groups from n = 32 participants which included NUMs, their managers, staff who work alongside the NUMs and the staff the NUMs manage. Data were analysed using thematic analysis and four themes were interpreted from the data, (i) lack of role clarity, (ii) the importance of clinical Leadership and forensic mental health knowledge, (iii) step up in responsibility and step down in pay and (iv) seeing the difference you make. The role of the NUM within a forensic mental health setting comes with a number of challenges, but also opportunities to enact change. An ongoing effort to better support those employed within the NUM role and make the role desirable for aspiring staff is critical to the sustainability of a skilled clinical workforce and quality of care in this complex setting. © 2023 The Authors.

Data were analysed using thematic analysis and four themes were interpreted from the data, (i) lack of role clarity, (ii) the importance of clinical Leadership and forensic mental health knowledge, (iii) step up in responsibility and step down in pay and (iv) seeing the difference you make. The role of the NUM within a forensic mental health setting comes with a number of challenges, but also opportunities to enact change. An ongoing effort to better support those employed within the NUM role and make the role desirable for aspiring staff is critical to the sustainability of a skilled clinical workforce and quality of care in this complex setting. © 2023 The Authors.

- Description: Background: This study explored the factors associated with timeliness of care in the healthcare seeking pathway among patients with lung cancer in Bangladesh. Methods: A structured questionnaire was used for data collection from 418 patients with lung cancer through face-to-face interviews in three tertiary care hospitals. Log-rank tests were performed to test differences in the length of intervals between points in healthcare by socioeconomic characteristics and care seeking behaviours of the patients. Cox Proportional Hazard (PH) regression analysis was performed to identify the predictors of the intervals after adjustment for variations in other variables. Results: A higher education level was associated significantly (p < 0.05) with a shorter interval between first contact with a healthcare provider (HCP) and diagnosis (median 81 days) and initiation of treatment (median 101 days). Higher monthly household income was associated significantly with a shorter time from first contact and diagnosis (median 91 days), onset of symptom and diagnosis (median 99 days), onset of symptom and treatment (median 122 days), and first contact with any HCP to treatment (median 111 days). Consulting with additional HCPs prior to diagnosis was associated significantly with longer intervals from first contact with any HCP and diagnosis (median 127 days), onset of symptom and diagnosis (median 154 days), onset of symptom and treatment (median 205 days), and first contact with any HCP to treatment (median 174 days). Consulting with informal HCPs was associated significantly with a longer time interval from symptom to treatment (median 171 days). Having more than one triggering symptom was associated significantly with a shorter interval between onset of symptoms and first contact with any HCP. Conclusion: The predictors for timeliness of lung cancer care used in this study affected different intervals in the care seeking pathway. Higher education and income predicted shorter intervals whereas consulting informal healthcare providers and multiple providers were associated with longer intervals. © 2023, The Author(s).

- Description: Introduction: Experiences of pregnancy and birth are important and have long-term impacts on the well-being of women and their families. Perinatal services should aim for care that promotes a positive childbearing experience, as well as optimizing health outcomes for the woman and newborn. This study aimed to understand the health system factors that promote a positive childbearing experience. Methods: Women who had a positive experience and had given birth in Australia in the previous 12 months were recruited for individual semistructured interviews. The interview guide focused on health system factors that participants credited with contributing to their positive experience of perinatal care. Interviews were conducted until data saturation was reached. Qualitative data were transcribed verbatim and analyzed using inductive thematic analysis. Results: Data from 36 interviews were thematically analyzed, and 4 major themes were generated: health care provider attributes, health system attributes, communication and decision-making, and experience of care. The salient factors that promoted positive experiences included care that was respectful and individualized with effective communication, access to midwifery continuity of care models, and good integration between services. Competent and professional health care providers who facilitated shared decision-making were also essential. Discussion: Although women often sought out care that promoted physiologic birth, they emphasized that the way they were cared for was more important than fulfilling specific birth aspirations. Quality maternity care has the capacity to support a woman's confidence in her own abilities and promote a positive, and sometimes transformative, childbearing experience. © 2022 The Authors.

Recently updated World Guidelines for Falls Prevention and Management strongly recommend evaluating patients’ concerns about falling as part of a multifactorial assessment. The aim of this systematic review was to evaluate the quality of falls risk perception measures for adults in a hospital setting. This review was conducted using the Consensus-based Standards for the selection of health Measurement Instruments guidelines and provides a comprehensive summary of these instruments, including psychometric properties, feasibility and clinical recommendations for their use. The review followed a prospectively registered protocol, in which a total of ten databases were searched between the years 2002 and 2022. Studies were included if the instruments measured falls risk perception and/or other psychological falls constructs, if they were conducted in a hospital setting and if the target population contained hospital inpatients. A total of 18 studies met the inclusion criteria, encompassing 20 falls risk perception measures. These falls risk perception instruments were grouped into five falls-related constructs: Balance Confidence, Falls Efficacy/Concern, Fear of Falling, Self-Awareness and Behaviour/Intention. Two of the patient reported outcome measures (PROMs) received Class A recommendations (Falls Risk Perception Questionnaire and the Spinal Cord Injury-Falls Concern Scale); however, this rating is only applicable for the populations/context described in the studies. Thirteen PROMs received Class B recommendations, solidifying the need for further validation studies of these PROMs. © 2023, The Author(s).

Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of triglycerides for CVD mortality. The cohort included 26 570 adult participants, among which 3978 had diabetes. People with higher triglycerides had a higher prevalence of diabetes at baseline.

Finding a place for organic waste-to-energy in Australian agribusiness
- Authors: Hurley, Craig

- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis seeks to understand Australian agribusiness engagement with approaches to generate energy from organic waste materials. Applications of modern bioenergy technologies, utilising agriculture residues to produce electrical, thermal and transport energy, have been well established in many parts of the world. There has been enthusiasm for bioenergy from agriculture to make a substantial contribution to Australia’s energy mix, but the agriculture sector, like Australia more generally, has been slow to transition to bioenergy technologies. Adopting the pragmatism research philosophy, this study applies the Multi-Level Perspective and Social Practice Approach frameworks to explore Australian agribusiness engagement with bioenergy systems, to produce energy from organic waste. A multi-methods qualitative research methodology is used to analyse the adoption of organic waste-to-energy approaches by Australian agribusiness, and to identify the critical drivers and barriers impacting these transitions. Except for sugar processors, Australian agribusiness adoption of organic waste-to-energy approaches is in its very early stages. The main drivers prompting agribusinesses to explore their organic waste-to-energy options are, agribusinesses experiencing problems with the cost and/or quality of their energy supplies, and/or problems with the social acceptance of their existing organic waste management practices. The main barriers to agribusinesses making the transition to bioenergy technologies, include financial factors such as the high capital costs of bioenergy plants and low returns on investment. Other barriers include a low level of awareness and understanding of bioenergy approaches in the agriculture industry, and in Australia more broadly, and a lack of consultative expertise to develop and service bioenergy systems. For organic waste-to-energy to play a more substantial role in Australian agriculture, support is needed to overcome critical barriers. This study finds policy and support mechanisms are required to encourage greater collaboration of small-scale agribusinesses and other relevant stakeholders. Investment is also needed to increase Australia’s awareness and understanding of organic waste-to-energy approaches, and to build the consultative expertise and skills-base to support the development of bioenergy systems.

- Description: Predicted increases in fire frequency and extent are being realised across Australia, bringing changes to the fire regime which may influence the availability of essential resources required by birds. However, few studies have examined either the impacts of fire frequency on birds or the impacts from both wildfire and planned burns, com bined. Birds were surveyed eight times across 84 sites in heathy dry forests in central Victoria, south-east Australia, from 2012 to 2014. Fire history records were retrieved from the 1970’s onwards, the time from which accurate planned burn records were kept. We developed mixed models to investigate how birds responded to time-since-fire and fire frequency, analysing total bird abundance, ten foraging guilds and 30 individual species. We found distinct responses by all modelled guilds and species to time-since-fire, along with evidence for responses to fire frequency. The greatest shifts in species’ abundances occurred during the first ten years post fire, with bird species commonly present across the stages greater than ten years since fire. For total bird abundance there was no statistically detectible difference between recently burnt forest (0-6 months) and other age classes. However, some guilds showed a significant drop in abundance in newly burnt vegetation (e.g. bark foragers, damp ground insectivores, those that feed on seeds close to the ground, tall shrub foragers). It is with guild and species’ responses that more differences across vegetation age classes became apparent. Significant increases in abundance were apparent in both the regrowth and new growth vegetation age classes, compared with older habitat (e.g. canopy foragers, damp ground insectivores, tall shrub foragers); open ground foragers were especially common in post-fire regrowth but then significantly declined. Other responses were more complex, with species’ preferences reflecting their foraging ecology. Some birds showed preferences across two age classes: sites that were young post-fire regrowth (6 months–2.5 years since fire) along with sites of old habitat (>35 years since fire), (e.g. Crimson Rosella, Scarlet Robin, Sulphur-crested Cockatoo), while some ground-foraging species became scarce in dense new-growth vegetation that appears 2.5–10 years post fire (e.g. Australian Magpie, Laughing Kookaburra and White-winged Chough). Such species may deserve specific management strategies to maintain populations in forests where substantial areas are burnt by wildfire or planned burns, over short periods of time. The model for total bird abundance showed a significant fire frequency response with birds preferring sites twice burnt within 35 years (e.g. bark and canopy-foraging guilds). Four guilds demonstrated a preference for sites frequently burnt, increasing in abundance as number of burns increased (nectarivores, open-ground foragers, seeds in trees foragers, tall shrub foragers). In contrast, two species appeared to prefer sites that had experienced low fire frequencies, a response not common to their guilds. Laughing Kookaburra (carnivore) and White-winged Chough (forages on open ground among trees) generally declined in abundance with increasing fire frequency. © 2023 Elsevier B.V.

- Description: While established in Asia, rice koji and miso are fermented foods that are becoming more popular in western countries. They have been shown to contain a variety of microorganisms, consisting of bacteria, yeasts, and fungal species. Many contemporary miso varieties are not pasteurized as consumers are looking for more natural products, and/or have the desire to consume fermented foods containing live microorganisms. While correctly prepared fermented foods are rarely associated with food safety outbreaks, incidences have been recorded. On these occasions, pathogenic, or spoilage microorganisms were introduced into the products from external sources such as the raw material or the processing environment. Consequently, hygiene and fermentation conditions need to be carefully monitored to ensure food safety. Furthermore, many of the production steps during koji and miso manufacture do not fit into contemporary food safety guidelines for foods. Although pH is a required food safety hurdle for fermented foods, this does not apply to nonacidic foods such as koji or miso. This review focuses on control of microbial pathogens and discusses the processes of miso fermentation, and how fermentation of rice koji and miso fits with current food safety hurdles in western countries. © 2023 The Authors.

Furthermore, many of the production steps during koji and miso manufacture do not fit into contemporary food safety guidelines for foods. Although pH is a required food safety hurdle for fermented foods, this does not apply to nonacidic foods such as koji or miso. This review focuses on control of microbial pathogens and discusses the processes of miso fermentation, and how fermentation of rice koji and miso fits with current food safety hurdles in western countries. © 2023 The Authors.

- Description: Although the country is transitioning out of COVID-19 lockdowns and easing restrictions, Australians are now facing increased costs of living. Global political unrest, interest rate rises, and inflation have seen the prices of fuel, food and household bills surge, increasing the strain on individuals and families. Fruit and vegetables have seen cost increases by almost 7% from last year, with this figure only estimated to rise. During the same period, however, takeaway food prices increased marginally by 0.7%, potentially due to government subsidy and voucher systems introduced post COVID-19 lockdowns. The strain of food prices is felt even more greatly by those living in regional, rural and remote Australia, with prices increasing due to freight costs. The Morwell Neighbourhood House (MNH) Food Bank provides emergency relief without requiring an appointment and is unrestricted by postcode or healthcare card status. The Food Bank is supported by St Vinnies Morwell, which provides $12,000 annually towards the cost of food, and by numerous community organisations, individuals and businesses. Demand for the Food Bank has increased steadily and particularly so during the COVID-19 pandemic. The immediate precursor to the People’s Kitchen was a 2019 project named Cooking for a Purpose. That involved GippsTAFE VCAL students preparing nutritious frozen meals using ingredients provided by MNH. The availability of frozen home-cooked meals has ensured that Food Bank clients have at least one nutritious hot meal per day. The CERC was commissioned to explore the activities of the MNH, gaining an insight into how the whole of person approach to food security was being implemented. This understanding was gained through the perspective of those who were paid employees, Volunteers or accessed the MNH services, outlining the benefits, barriers and future suggestions for the MNH operations when addressing food security in the Latrobe Valley. Data were collected between 2022 - 2023 using a mixed methods approach to understand the impact of the MNH services on participants. Participants included MNH stakeholders, staff, Volunteers, secondary school students and people who accessed the MNH services. In addition to this, a comprehensive literature review was performed to understand the global landscape of food insecurity, exploring how people access Food Banks, the opportunities that arise from engaging with food security service activities and the perspectives of employees who ran these services.

- Description: The paper investigates the freeze–thaw resistance and sorptivity behavior of fine-grained alkali-activated concrete cured at ambient temperature. A blended binder system containing fly ash, ground granulated blast furnace slag, and silica fume was used. A combination of sodium hydroxide and sodium silicate was used as an activator. The freeze–thaw resistance was evaluated based on mass loss (scaling), and the extent of internal damage was assessed by testing the ultrasonic time at different cycles. Initial and secondary sorptivity coefficients were calculated based on the cumulative water absorption values at different time intervals. Alkali content, sodium silicate to sodium hydroxide ratio, and water to binder ratio were investigated. The experimental results showed that water to binder ratio is the most significant parameter for the scaling; higher ratios result in higher scaling. In terms of internal damage, alkali content is the most significant. The increase of alkali increased the amount of internal damage in the concrete. The initial sorptivity coefficient increased with the water and alkali content and decreased with the silicate content. The secondary sorptivity coefficient showed no significant change with the investigated parameters. © 2022 The Authors.

- Description: There is growing awareness that biodiversity loss poses a significant risk to the global economy, but a lack of clarity on what this means for corporations, and how they are responding. This study provides a first quantitative assessment of biodiversity risk exposure across the world's largest listed companies, compared with their adoption of biodiversity policies, through analysis of disclosures from a sample of 11,812 companies from 2004 to 2018. We find that companies have started responding strategically to biodiversity risk, with 29% having adopted a biodiversity policy by 2018. However, around $7.2 trillion of total enterprise value remains exposed to unmanaged biodiversity risk. Companies in sectors with material impacts on biodiversity tend to have high levels of response, but there is poorer responsiveness to material biodiversity dependency risks. A natural-capital-based view (NCBV) of the firm is proposed to theorise how corporations are constrained by both their impacts and dependencies on natural capital. © 2022 The Authors.
