Abstract: Highly Pathogenic Avian Influenza (HPAI) is a high morbidity and mortality zoonotic disease, which threatens poultry and human health. An outbreak of disease in China requires strict slaughter and disposal of all chickens within a three-kilometer radius, incurring large private costs for farmers and encouraging black market transactions. A stated preference survey of 331 farmers across six provinces in China was conducted in 2015, in order to measure the responsiveness of farmers to accept various compensation prices for safely disposing of HPAI infected chicken. Findings suggest that about 25% and 40% of farmers in South and North China respectively would not adopt safe disposal at the current compensation price (10 yuan/bird) offered by the government. However, 80% of farmers would adopt safe disposal if the compensation price increased to 14.1 yuan in South China and 18.9 yuan in North China. The adoption of safe disposal by farmers was positively and significantly influenced by compensation price (p=0.000) and regular contact with epidemic prevention staff (p=0.094). However, adoption was negatively and significantly influenced by net farm income (p=0.100) and chicken production income percentage (p=0.014). Although half of (51%) of farmers were willing to receive zero compensation, a reasonable compensation scheme along with strengthened supervision, may be considered the most effective strategy to encourage safe disposal of HPAI infected chicken and reduce the risks associated with black market transactions.

Abstract: The potential link between certified organic farming and bio ersity and conservation remains unexplored in Australia, despite the country having the world's largest amount of certified organic farmland and unprecedented bio ersity loss. This study modelled the spatial effects of organic farming (intensity of local farming systems), environmental heterogeneity, and urbanisation on two widely studied environmental taxa - vascular plant and bird species richness (surrogate measures of bio ersity) - in South Australia, using a unique certified organic farming postcode level dataset from 2001 to 2016 (N = 5440). The spatial Durbin error model results confirmed the positive spatial congruence of organic farming with greater vascular plant species richness, whereas only weak to no significant evidence was found for bird species richness. Landscape features (habitat heterogeneity) and green vegetation (a proxy indicator of resource availability) - rather than organic farming - appeared to be most associated with bird species richness. Both plant and bird species richness were positively associated with habitat heterogeneity (land cover ersity and elevation range), plant productivity and proportion of conservation land and water bodies. Whereas, increased anthropogenic land use for cropping and horticultural farming, soil type ersity and proximity to the coast significantly reduced species richness of both taxa. The results suggest that a multi-scale spatially refined bio ersity conservation strategy, with spatial targeting that promotes low intensive farming systems and increases landscape heterogeneity to provide quality habitat (a whole of landscape approach by incorporating private agricultural landholders), could be beneficial for bio ersity conservation.

Abstract: Little is known about the interdependence between surface and groundwater extractions and trade. Groundwater metered extraction was modelled at the bore level (n = 1,890) in the Goulburn‐Murray Irrigation District, Victoria, from 2007–08 to 2016–17 to understand its associations with hydrologic, location, climatic, and economic factors. Surface and groundwater extractions were found to be substitutes for each other, with groundwater extractions statistically significantly increasing when: (i) bores were closer to surface water watercourses, (ii) surface water allocations and rainfall were lower, and (iii) surface water temporary market prices and entitlement trade out‐of‐zone volumes were higher. Other key groundwater extraction influences included pumping costs and commodity prices.

Abstract: Irrigators in the Murray–Darling Basin (MDB) of Australia face a salinity triple threat, namely: dryland salinity, surface-water, and groundwater salinity. Water trading has now been adopted to the point where it is a common adaptation tool used by the majority of irrigators in the Basin. This study uses a number of unique water market and spatial databases to investigate the association between the severity and extent of areas which suffer from salinity and permanent trade over time, holding other regional characteristics constant. It was found that larger volumes of permanent water were likely to be sold from areas suffering from higher dryland salinity. In addition, increases in the concentration of groundwater salinity was found to decrease volumes of surface-water entitlements sold, providing evidence that groundwater entitlements (where they are viable substitutes) have been increasingly used as substitutes for surface-water entitlements in recent years. Other key influences on water sales included water market prices and net rainfall.

Abstract: Environment-related migration in China is shaped by a complex set of factors and their interactions. The central question addressed in this study is: how does economic well-being at the household level change after displacement and what shapes it? Based on a survey of households displaced in the Ganzi Tibetan Autonomous Prefecture, Sichuan Province between 2004 and 2009, the study demonstrates that livelihood reconstruction is influenced by a mixture of household, institutional and community contextual factors. Government-led resettlement could be an effective approach to ersifying livelihood and building the future resilience of households to rural poverty and environmental change. The study contributes to the discussion on economic outcomes of resettlement due to environmental change, which can assist in suggesting how to improve the economic well-being of the recently resettled populations. Further resettlement action and policy measures need to be adjusted based on a more comprehensive understanding of the variety of factors that affect people's overall well-being to develop better ways to ensure improved livelihoods and long-term well-being of the displaced.

Abstract: There has been little work conducted on how landholders’ farm management approaches and financial capital (specifically (i) farm method such as organic farming and (ii) financial profitability) may impact mental health. In particular, there is emerging evidence that an increase in natural farm capital and environmental conditions may improve farmers’ wellbeing. We used a 2015–2016 survey, which randomly s led 1000 irrigators from the southern Murray–Darling Basin, to model the drivers of irrigators’ psychological distress. Results highlight that worsening financial capital (namely, lower farmland value, higher farm debt, lower percentage of off-farm income, lower productivity change over the past five years, and lower net farm income) was the most statistically significant factor associated with increased irrigator distress. In addition, there was some evidence that being a certified organic irrigator was also associated with lower psychological distress however, it was only weakly significant in our overall model, with the most significance within the horticultural industry model. Contrary to expectations, drought and water scarcity were not the main drivers of psychological distress in the time-period studied, with their influence seemingly through reducing financial capital as a whole.

Abstract: Recently, concern has increased globally over farmers’ mental health issues. We present a systematic review of the outcomes, locations, study designs, and methods of current studies on farmers’ mental health. In particular, this review aims to fill an important gap in understanding of the potential key risk factors affecting farmers’ mental health around the world. 167 articles on farmer mental health were included in a final systematic review using a standardized electronic literature search strategy and PRISMA guidelines. The four most-cited influences on farmers’ mental health in the reviewed literature respectively were pesticide exposure, financial difficulties, climate variabilities/drought, and poor physical health ast injuries. The majority of studies were from developed countries, most specifically from the United States, Australia, and the United Kingdom. Comparative studies on the mental health of farmers and other occupational workers showed mixed results, with a larger portion identifying that psychological health disturbances were more common in farmers and farm-workers. Knowledge of farmer psychological disorder risk factors and its impacts are essential for reducing the burden of mental illness. Further research will be required on climate change impacts, developing country farmers’ mental health, and information on how to reduce help-seeking barriers amongst farmers.

Abstract: The control of food-borne outbreaks caused by Listeria monocytogenes in humans relies on the timely identification of food or environmental sources and the differentiation of outbreak-related isolates from unrelated ones. This study illustrates the utility of whole-genome sequencing for examining the link between clinical and environmental isolates of L. monocytogenes associated with an outbreak of hospital-acquired listeriosis in Sydney, Australia. Comparative genomic analysis confirmed an epidemiological link between the three clinical and two environmental isolates. Single nucleotide polymorphism (SNP) analysis showed that only two SNPs separated the three human outbreak isolates, which differed by 19 to 20 SNPs from the environmental isolates and 71 to ,000 SNPs from sporadic L. monocytogenes isolates. The chromosomes of all human outbreak isolates and the two suspected environmental isolates were syntenic. In contrast to the genomes of background sporadic isolates, all epidemiologically linked isolates contained two novel prophages and a previously unreported clustered regularly interspaced short palindromic repeat (CRISPR)-associated (Cas) locus subtype sequence. The mobile genetic element (MGE) profile of these isolates was distinct from that of the other serotype 1/2b reference strains and sporadic isolates. The identification of SNPs and clonally distinctive MGEs strengthened evidence to distinguish outbreak-related isolates of L. monocytogenes from cocirculating endemic strains.

Abstract: Economic instruments have been increasingly adopted by governments around the world to address water scarcity problems because of their potential to achieve environmental outcomes in more cost‐effective ways. This is the first study to estimate the willingness to accept compensation for land fallowing in rural China. Using survey data collected from village representatives in Northern China (mainly village leaders, party secretaries and village accountants), our results suggest that in groundwater irrigated s le villages, at least 28 per cent of respondents have a compensation expectation lower than the standard level of 500 yuan/mu/year for one season of fallowing set by the Government. Water scarcity measures such as irrigation supply reliability and depth‐to‐groundwater within a village are found to have statistically significant effects on the likelihood of fallowing land in groundwater irrigated villages.
