A resilience-based approach to regional natural resource management planning in NSW
Creators: name: Parkes, Claire
Publisher: name: University Of Tasmania
Year: 2023

description: Natural resource management programs around Australia are led, coordinated and implemented by regionally-based organisations. In New South Wales (NSW) the thirteen catchment management authorities have legislative responsibilities to prepare strategic catchment plans that coordinate and integrate the natural resource management activities of community and government. These plans are about to be revised and new approaches to planning practice are being sought and explored. Resilience theory is an emerging field of research and practice that is being proposed by some institutions as a new and potentially worthwhile approach to dealing with complexity, uncertainty and inevitable future change. Resilience theory conceptualise problems as evolving from complex and interlinked social-ecological systems. It identifies those areas in systems where resilience may be being undermined and therefore could tip into another system state, or where a system may be currently stuck in an undesirable but resilient state and therefore requires active transformation. The aim of this study was to explore how resilience principles and methods could be applied to a specific planning project - the preparation of an integrated catchment plan. It also aimed to assess the strengths and weaknesses of resilience thinking in this context, and identify implications for natural resources policy in NSW. The study found that resilience concepts are is best applied within an overall strategic planning process that is familiar to the planning agency and that derives elements from rational, collaborative, integrative and adaptive planning theories, rather than using resilience thinking as an allencompassing approach to developing the plan. It found that the greatest strengths of resilience thinking are in its systems-based approach to problem definition, and in its ability to provide a strong rationale for the management actions selected. Although many aspects of a resilience-based approach are familiar to many natural resource managers, there are still challenges for the wider uptake of a resilience approach in natural resource management in NSW. These include a perception that natural resource management is limited to the biophysical and ecological rather than the social and economic, accountability arrangements that are not conducive to adaptive management and the challenges in garnering commitment to an approach that represents a shift away from the dominant natural resource management paradigm.

description: This paper focuses on the Drakensberger as competitive beef breed of cattle. The Drakensberger is a medium-framed black cattle breed, indigenous to South Africa. The breed fares well in key requirements for successful cattle farming, and although the breed has much to offer, it does not enjoy a large market share in the country. Resultantly, this low market share raises questions as to why an indigenous, quality cattle breed has a low market share. The primary objective was to determine the South African farmerâ€™s perception on Drakensberger as cattle breed in the market. This was achieved by the secondary objectives that identify and describe the competitive South African cattle breeds, identify the characteristics a South African farmer looks for a cattle breed, measure the Drakensbergerâ€™s performance against these identified characteristics, and to clarify the low market share. The literature study reviewed the background of the South African cattle industry, identified the competitors in the cattle market, and also assessed the Drakensberger breedâ€™s potential. From the literature it was evident that the breed has no fatal flaws. It outperforms certain other more popular cattle breeds, and the Drakensberger is also exceptionally well adapted for the diverse South African conditions, performing well on even low quality sour grass veld conditions. The empirical research employed qualitative research to determine the characteristics important to South African cattle farmers. Additionally, quantitative research, using a structured questionnaire, was employed to determine cattle breedersâ€™ perceptions of the Drakensberger and competitive cattle breed. The data showed a high reliability coefficient of 0.83 (as calculated by the Cronbach Alpha). The results showed that farmers prefer cattle breeds possessing hardiness, high fertility, high weaning weight and, surprisingly, the colour of the breed. The colour preference negatively impacts on the Drakensberger as South African farmer prefer red and not black cattle breeds (such as the Drakensberger). However, farmers farming with the Drakensberger are very satisfied with the breedâ€™s performance, even more so that the farmers of other cattle breeds are with their breeds.

description: Purpose - The paper analyzes the decision-making process on whether or not to commercialize genetically modified (GM) crops in the current EU environment, for several agriculture industry sectors. This cross-industry analysis provides us insights in the (future) market dynamics of GM crop (applications) in the EU environment. Methods - Agribusiness stakeholders of six agricultural industry sectors were interviewed on their GM policy, using a semi-structured interview guide. This data were analyzed by content analysis. Principal results - The cross-industry analysis on GM policies between companies belonging to the same and to different agriculture industry sectors, unveils several alignments of common central arguments in their decision-making processes that precede this actual GM business policy. Accordingly, three strong hypothetical policy congruities were identified, between (1) the agricultural biotechnology and compound feed industry, whoâ€™s policies are motivated by their conviction that GM imports are a by-default reality in the EU, (2) between NGOâ€™s and the organic industry, whoâ€™s policy is driven by their pursued agricultural ideals (that oppose both to the current (globalizing) agricultural system and to GM crops as they reinforce this system), and (3) between all the food actors, whoâ€™s GM business policy is primarily motivated from a (black-or-white) marketing consideration. Finally, our insights (1) highlight the â€œtalking at cross-purposesâ€ in the GM debate between different agriculture industry sectors, and (2) unveil several underlying reasons for the locked-in situation with GM crops in the current EU environment.

description: In this work we suggest a statistical mechanics approach to the classification of high-dimensional data according to a binary label. We propose an algorithm whose aim is twofold: First it learns a classifier from a relatively small number of data, second it extracts a sparse signature, {\it i.e.} a lower-dimensional subspace carrying the information needed for the classification. In particular the second part of the task is NP-hard, therefore we propose a statistical-mechanics based message-passing approach. The resulting algorithm is firstly tested on artificial data to prove its validity, but also to elucidate possible limitations. As an important application, we consider the classification of gene-expression data measured in various types of cancer tissues. We find that, despite the currently low quantity and quality of available data (the number of available samples is much smaller than the number of measured genes, limiting thus strongly the predictive capacities), the algorithm performs slightly better than many state-of-the-art approaches in bioinformatics.

description: Mushrooms containing amatoxin are found worldwide and represent a challenging poisoning for the clinician and consulting poison center. This study evaluates the experience of a large poison system with possible amatoxin-containing mushroom ingestion calls. A 10-year retrospective review of the California Poison Control System database was performed for amatoxin mushroom ingestion calls resulting in hospitalization. Cases found were abstracted and data statistically analyzed for association with a composite endpoint of death, liver transplant, and/or the need for dialysis. Amatoxin-containing mushroom calls are infrequent with the vast majority (98.4 percent) coming from Northern California during the rainier first and fourth quarters (October through March) of the year. Elevated initial aminotransferase activities and international normalized ratios were predictive of the composite negative outcome. The mortality plus liver transplant and hemodialysis composite rate was 8.2 percent, consistent with current literature. The California Poison Control System has relatively few amatoxin-containing mushroom ingestion calls that result in hospitalization but those that are reported mostly occur in Northern California. Treatment bias towards the sickest patients may explain the association of intravenous fluid use or treatment with acetylcysteine or silibinin with meeting the composite outcome. The initial presence of elevated hepatic aminotransferase activity and international normalized ratios are poor prognostic indicators and are likely reflective of late presentation, an advanced toxic phase of amatoxin poisoning, and/or delays in time to obtain poison center consultation.

description: Increasing Greenhouse-gas emissions and related climate effects require mitigation strategies. Also emissions caused by agriculture are brought into the focus of political debate. Particularly peatland cultivation, inducing significant CO2 emissions is being discussed more and more. Our study aims to answer the question of whether changes of peatland management can serve as costefficient emission-mitigation strategy. We have built an economic model in which farm-individual and plot-specific CO2-abatement costs of selected landuse strategies are calculated by contrasting effects on the agricultural income with the related reduction in greenhouse-gas emissions. With respect to microeconomic data we use a dataset collected in six German regions while data on emission-factors originates from own measurements. Results show that CO2-abatement costs vary due to different levels of land-use reorganisation. Reasonable emission reductions are mainly achieved when agricultural intensity is clearly decreased. Agricultural income forgone varies significantly due to production conditions and mitigation strategies. However, even when economic costs are high they may be balanced by high emission reductions and may not result in high abatement costs. Nevertheless, CO2-reductions benefits appear to be social and costs private. Agro-environmental programmes must be implemented to compensate resulting income losses.

description: Precise knowledge of the cross sections for neutrino interactions with nuclei is important not only for existing experiments but also for development of future detectors. When momentum transferred to the nucleus by the probe is high enough, the impulse approximation is valid, i.e. the nucleus can be described as composed of independent nucleons and the interaction happens between neutrino and a single bound nucleon. The cross section of the nucleus is then expressed as an integral of the free cross section (modified by the off-shell effect) folded with the so-called spectral function, describing the distribution of nucleon momenta and energies. I present results obtained for the approximate spectral functions of argon and calcium. The accuracy of the approach is verified by comparison with a broad spectrum of precise electron-scattering data for the calcium target. Some of these data lie in the kinematical region corresponding to neutrino interactions what indirectly shows that a similar level of accuracy is achieved for neutrinos. The calculated Ar(nu_mu,mu) cross section is significantly lower than the one predicted within the Fermi gas model.

description: The cost efficiency of the dairy subsector has been analyzed using data for four FADN regions in Poland for the period 2004/05-2007/08. The cost inefficiency indexes have been calculated for each farm from each region. Overall, all applied measures have been statistically significant in the heteroskedasticity consistent estimation except for the farmerâ€™s age. Regional differences have been pronounced and the benchmark Mazowsze and Podlaskie region showing higher cost efficiency than two other major regions, but not a minor, in terms of dairy production, MaÅ‚opolska and PogÃ³rze region. It is likely that the regional specialization will continue with the benchmark region gaining further advantage. A sub-regional analysis has been recommended for the future study.

description: ABSTRACT
 Attention to nature based solution in watershed conservation and management is increasing in the developing world as chemicals continue degrading agricultural land; garbage and urban sewage infrastructure are sediment clogged. The realization of significance of watersheds is fundamental for utilization that is sustainable where urban livelihoods recreation and economies are majorly dependent on the utilization of natural resources.Lake Ullal is characterized by surrounding population density that is high made up of urban population characterized by raw sewage disposal, garbage and flow of debris from construction. The catchment areas engage in agriculture characterized by use of pesticides and fertilizers that dissolve in the flowing water to the lake. These materials pose a serious threat to the watersheds.The high population density at the catchment has led to intensive agriculture that is characterized by pressure to yield more output to match the demand. There is a big gap between institutional and policy framework development at the high level and real implementation of proposals on the ground to combat soil erosion,land degradation and need to decrease the sediment load. The study mainly focused on the catchments of Ullal while assessing anthropogenic activities that have led to degradation of the lake. This provides an insight of nature based solution that can be adapted to conserve and manage the precious lake. The concept of Nature based Solution (NBS) provides adequate recommendation that can be adopted to salvage the lake for future generations.Subject area: GeographyKey words:Nature based solution, watersheds, catchment, degradation and conservation based solution that can be adapted to conserve and manage the precious lake.

description: The thermal management of cryogenic storage tanks requires advanced control strategies to minimize the boil-off losses produced by heat leakages and sloshing-enhanced heat and mass transfer. This work presents a data-assimilation approach to calibrate a 0D thermodynamic model for cryogenic fuel tanks from data collected in real time from multiple tanks. The model combines energy and mass balance between three control volumes (the ullage vapor, the liquid, and the solid tank) with an Artificial Neural Network (ANN) for predicting the heat transfer coefficients from the current tank state. The proposed approach combines ideas from traditional data assimilation and multi-environment reinforcement learning, where an agent's training (model assimilation) is carried out simultaneously on multiple environments (systems). The real-time assimilation uses a mini-batch version of the Limited-memory Broyden-Fletcher-Goldfarb-Shanno with bounds (L-BFGS-B) and adjoint-based gradient computation for solving the underlying optimization problem. The approach is tested on synthetic datasets simulating multiple tanks undergoing different operation phases (pressurization, hold, long-term storage, and sloshing). The results show that the assimilation is robust against measurement noise and uses it to explore the parameter space further. Moreover, we show that sampling from multiple environments simultaneously accelerates the assimilation.

description: As part of the gradual expansion and abolition of EU milk quotas, the Irish government has approved the allocation of milk quota to a small number of new entrants to dairy production. The objective of this study was to describe the characteristics of new entrant dairy farm businesses developing within the Irish dairy industry in terms of geographical distribution, planned production system characteristics and intended operational scale and expected profitability based on an analysis of successful applications and business plans to the Irish New Entrant Dairy Scheme over a 3 year period. A total of 230 applications and business plans of entrants who received up to 200,000 litres of milk quotas through the New Entrant Scheme from 2009-2011, were analysed for the effects of region, age, household income, previous dairy experience, and education on overall business plan expectations. The results show that a youthful, highly educated and highly resourced group of new farmers are using the New Entrant Scheme to enter the Irish dairy industry. Applicant age has a significant impact on available investment equity and expectations, as younger entrants have less owned resources, are increasingly reliant on additional borrowing and have significantly increased expectations for the productive capacity of their potential farm businesses when compared to older entrants. The results provide a further indication that quota abolition is likely to result in an increased regional polarisation of milk production within Ireland with increased intensity of production within traditional milk production areas in the south.

description: Stochastic backgrounds or relic gravitons, if ever detected, will constitute a prima facie evidence of physical processes taking place during the earliest stages of the evolution of the plasma. The essentials of the stochastic backgrounds of relic gravitons are hereby introduced and reviewed. The pivotal observables customarily employed to infer the properties of the relic gravitons are discussed both in the framework of the $Λ$CDM paradigm as well as in neighboring contexts. The complementarity between experiments measuring the polarization of the Cosmic Microwave Background (such as, for instance, WMAP, Capmap, Quad, Cbi, just to mention a few) and wide band interferometers (e.g. Virgo, Ligo, Geo, Tama) is emphasized. While the analysis of the microwave sky strongly constrains the low-frequency tail of the relic graviton spectrum, wide-band detectors are sensitive to much higher frequencies where the spectral energy density depends chiefly upon the (poorly known) rate of post-inflationary expansion.

description: The United States Congress has yet to pass new farm program legislation after the expiration of the 2008 Farm Bill last year. Most of the provisions of the 2012 farm program have been extended until September 30, 2013 to cover the 2013 crop. Farm bill legislation is always subject to wide array of proposals promoted by different interest groups and that is occurring this time as well. Two main ideas have surfaced with rather broad agreement. It is generally accepted that direct payments will not be included in the next farm bill. These payments have been made to producers regardless of production or prices. The other main area of agreement is that federally subsidized multi-peril crop insurance should be protected and become the primary safety net component of the next farm bill. Crop insurance protects producers very well in the event of individual production losses. However, the potential for crop insurance to provide a long term safety net against loss of price is yet to proven. Producers have experienced the benefit of several years of rising crop prices and therefore, insurance levels. If prices decline for a multi-year period, it remains to be seen if producers can reduce their cost of production enough to deal with the lower safety net in the event of a loss. In addition, crop insurance provides no protection against price losses on the portion of yield above the guaranteed level.

description: Public policy favoring the organization of agriculture through the farm family business has been a long held foundation of agricultural policy in the industrialize democracies. Much of this policy has been based upon an ideal typology that focuses upon the relationships of the farm and the family to the land and the processes that shape those relationships. An ideal typology that focuses on relationships provides little quantitative data and while such typology may be appropriate in developing it may not be appropriate to the implementation of such policy. The implementation of policy often requires some quantifiable data that will determine the inclusion or exclusion of farms for policy benefits. Given that policy favors family farms a key to their sustainability is the ability to transfer the farm land and the farm business to a successor generation. The complexity of the process of intergenerational transfer is little understood and under researched. This lack of research and the information that could be derived for it has affects the formulation of public policy. The FARMTRANSFERS international farm succession research project has over 15,500 replications of a postal questionnaire. Accepting the limitation of time, location and culture it has produced a valuable and unique set of data that upon analysis yields insights into differences in farm policy based upon legal system and culture. A summary of selected policies is offered in by the authors of this paper. The paper concludes with observations on the future of the farm family business and the attributes of the successor of the future.

description: The Beta Pictoris Moving Group is a nearby stellar association of young (12Myr) co-moving stars including the classical debris disk star beta Pictoris. Due to their proximity and youth they are excellent targets when searching for submillimetre emission from cold, extended, dust components produced by collisions in Kuiper-Belt-like disks. They also allow an age independent study of debris disk properties as a function of other stellar parameters. We observed 7 infrared-excess stars in the Beta Pictoris Moving Group with the LABOCA bolometer array, operating at a central wavelength of 870 micron at the 12-m submillimetre telescope APEX. The main emission at these wavelengths comes from large, cold dust grains, which constitute the main part of the total dust mass, and hence, for an optically thin case, make better estimates on the total dust mass than earlier infrared observations. Fitting the spectral energy distribution with combined optical and infrared photometry gives information on the temperature and radial extent of the disk. From our sample, beta Pic, HD181327, and HD172555 were detected with at least 3-sigma certainty, while all others are below 2-sigma and considered non-detections. The image of beta Pic shows an offset flux density peak located near the south-west extension of the disk, similar to the one previously found by SCUBA at the JCMT. We present SED fits for detected sources and give an upper limit on the dust mass for undetected ones. We find a mean fractional dust luminosity f_dust=11x10^{-4} at t=12Myr, which together with recent data at 100Myr suggests an f_dust propto t^{-alpha} decline of the emitting dust, with alpha > 0.8.

The new experiments significantly reduce systematic uncertainties in the DSAM technique. The J$^π$ = $2^+_1$ state at 3.37 MeV has $τ$ = 205${\pm}$(5)$_{stat}\pm$(7)$_{sys}$ fs corresponding to a $B$($E2\downarrow$) of 9.2(3) $e^2$fm$^4$ in broad agreement with many calculations. The J$^π$ = $2^+_2$ state at 5.96 MeV was found to have a $B$($E2\downarrow$) of 0.11(2) $e^2$fm$^4$ and provides a more discriminating test of nuclear models. New Green's Function Monte Carlo (GFMC) calculations for these states and transitions with a number of Hamiltonians are also reported and compared to experiment.

description: Harmonic model predictive control (HMPC) is a recent model predictive control (MPC) formulation for tracking piece-wise constant references that includes a parameterized artificial harmonic reference as a decision variable, resulting in an increased performance and domain of attraction with respect to other MPC formulations. This article presents an extension of the HMPC formulation to track periodic harmonic/sinusoidal references and discusses its use for tracking arbitrary trajectories. The proposed formulation inherits the benefits of its predecessor, namely its good performance and large domain of attraction when using small prediction horizons, and that the complexity of its optimization problem does not depend on the period of the reference. We show closed-loop results discussing its performance and comparing it to other MPC formulations.

description: This paper presents a method for assessing the personal construct systems of young children (ages 4 to 6) regarding the notion of 'nature,' conducted at a Montessori Casa in Toronto, Ontario. Images from the participants' drawings of 'nature' were used in a card sorting exercise and as elements in a modified repertory grid test. Member checking was conducted through recorded conversations with the children throughout the process to minimize the influence of my own construct system. I conducted content analyses of the initial drawings, and made structural measurements and statistical analyses of the card sort and repertory grid data. The limited results indicate that this modified form of repertory grid test is reliable and useful for assessing the structure of young children's construct systems regarding 'nature.' Using Personal Construct Theory may facilitate the development of more participatory, engaging, and effective Environmental Education programs.

description: Farmers have been encouraged, for many years, to apply a more formal and rigorous planning approach to their business management functions. The preferred documents accompanying the planning are strategic plans or business plans. Setting a strategy refers to developing a plan that documents where a farmer sees his or her business in the future and what management and investment decisions have to be made to attain the vision. Business plans are more focused on a specific concept or project, usually within a defined timeline. The two planning functions can exist on a standalone basis but more typically, one would expect a business plan to harmoniously be working toward achieving the longer term strategy. Strategic plans will generally have a five year horizon with a three to five year focus for business plans. Plans that have a one year timeline are usually more operational in nature. Having an operational plan would be a minimum expectation. But the reality is that the majority of farms have no formal plans at all. Farmers will have operational plans but they reside in their heads. The absence of any formal planning hierarchy does not, in itself, result in failure. In fact, many farms have been very successful with no written plans at all. This paper will not argue the relative merits of strategic, business or operational plans. It will present an alternate approach to planning.

description: We present a comprehensive rheological study of a suspension of thermosensitive particles dispersed in water. The volume fraction of these particles can be adjusted by the temperature of the system in a continuous fashion. Due to the finite polydispersity of the particles (standard deviation: 17%), crystallization is suppressed and no fluid-crystal transition intervenes. Hence, the moduli $G'$ and $G"$ in the linear viscoelastic regime as well as the flow curves (shear stress $σ(\dotγ)$ as the function of the shear rate $\dotγ$) could be measured in the fluid region up to the vicinity of the glass transition. Moreover, flow curves could be obtained over a range of shear rates of 8 orders of magnitude while $G'$ and $G"$ could be measured spanning over 9 orders of magnitude. Special emphasis has been laid on precise measurements down to the smallest shear rates/frequencies. It is demonstrated that mode-coupling theory generalized in the integration through transients framework provides a full description of the flow curves as well as the viscoelastic behavior of concentrated suspensions with a single set of well-defined parameters.

description: Civilizations historically share a common trajectory of soil degradation through cyclical technological advancements and soil productivity. A living soil food web provides a holistic approach to eco-regenerative properties as an expression of the soil microbial community (SMC) in relationship to plants and other organisms. Acknowledging soil ecology’s identification of plant-SMC-plant signalling, this study’s mixed methodology addressed the question of how an eco-centred perspective of living soil and plant relationships can contribute to this understanding. Using quantitative field analysis, Cornus alternifolia was identified to curate a SMC at a lower than anticipated fungal:bacterial (F:B) ratio, across three different seral stages in a southwestern Ontario mixed deciduous forest. Qualitative interviews and analyses of three land management industry discussion groups, using Grounded Theory methodology, affirmed a variable understanding of a SMC-plant eco-context, and identified challenges and leverage potentials for industry eco-regeneration focused on land management and cultural changes, as well as ecology.
The status and conservation of shorebird habitat in South-east Tasmania

description: Census data from 11 sites of shorebird habitat in South-east Tasmania from the 1960s, 1970s and 1980s were examined qualitatively and by using analysis of variance techniques. The aim was to establish whether the numbers of shorebirds using these sites as feeding, breeding and roosting habitat had changed over that time period, and to establish whether a relationship existed between observed changes in numbers and habitat alteration and loss at the sites. Of the eight sites monitored intensively during both the 1960s and 1980s sampling periods, the abundance of shorebirds decreased at three sites (Lauderdale, Orielton Lagoon and Sorell), no change in abundance was recorded at two sites (Clear Lagoon and Barilla Bay), and three sites (Pipeclay Lagoon, Calverts Lagoon and South Arm Neck) experienced an increase in shorebird abundance. At those same eight sites, the number of species present decreased at five sites (Lauderdale, Clear Lagoon, South Arm Neck, Sorell and Barilla Bay) between the 1960s and the 1980s, no change in species richness was recorded at two sites (Pipeclay Lagoon and Orielton Lagoon), and one site (Calverts Lagoon) experienced an increase in species numbers. No clear trends were evident at the remaining three sites. The reasons for the changes in shorebird numbers at the sites were (1) a shift in site preference and the pattern of site utilization, and (2) a decline in the abundance of some species utilizing the sites. It is highly likely that these changes were related to changes in habitat, although a direct cause and effect relationship could not be proved. Urban pressure was identified as the primary cause of degradation at the sites. The over-riding management priority was identified as the conservation of the major sites of feeding, breeding and roosting habitat for shorebirds. Secondary priorities included the development of management plans and appropriate levels of management for each site, establishment of wetland conservation policies by the state and local governments, community education of wetland values, involvement of the Bird Observers' Association of Tasmania in an advisory capacity in planning for wetland areas, and the undertaking of ecological research at the sites. The protective reservation of shorebird habitat at Pittwater and South Arm Neck is urgently required.

description: Atmospheric escape in exoplanets has traditionally been observed using hydrogen Lyman-$α$ and H-$α$ transmission spectroscopy, but more recent detections have utilised the metastable helium triplet at 1083$~$nm. Since this feature is accessible from the ground, it offers new possibilities for studying atmospheric escape. Our goal is to understand how the observability of escaping helium evolves during the lifetime of a highly irradiated gas giant. We extend our previous work on 1-D self-consistent hydrodynamic escape from hydrogen-only atmospheres as a function of planetary evolution to the first evolution-focused study of escaping hydrogen-helium atmospheres. Additionally, using these novel models we perform helium triplet transmission spectroscopy. We adapt our previous hydrodynamic escape model to now account for both hydrogen and helium heating and cooling processes and simultaneously solve for the population of helium in the triplet state. To account for the planetary evolution, we utilise evolving predictions of planetary radii for a close-in 0.3$~M_{\rm Jup}$ gas giant and its received stellar flux in X-ray, hard and soft EUV, and mid-UV wavelength bins assuming a K dwarf stellar host. We find that the helium triplet signature diminishes with evolution. Our models suggest that young ($\lesssim 150$~Myr), close-in gas giants ($\sim 1$ to $2~R_{\rm Jup}$) should produce helium 1083$~$nm transit absorptions of $\sim 4\%$ or $\sim 7\%$, for a slow or fast-rotating K dwarf, respectively, assuming a 2$\%$ helium abundance.
