Urban green infrastructure (UGI) has the potential to address a wide range of challenges associated with rapidly growing cities in a changing climate, while also providing multiple environmental, economic and social benefits. However, the location of projects is often determined according to a single potential benefit rather than a set of benefits. Furthermore, while UGI is recognized as a successful strategy to support resilience in many cities around the world, it has not been implemented in Uruguay. This study develops a model to identify priority areas in need of green infrastructure in Montevideo, Uruguay. The GIS-based model, termed the “Green Infrastructure Suitability Model” (GISM) is based on a multi-criteria decision analysis approach and is similar in structure to land suitability analysis. The model considers a range of socioeconomic, biophysical and environmental factors to prioritize the need for UGI across the case-study region. Resulting suitability maps identify areas for multifunctional UGI localization in places where benefits can be maximized. The GISM has potential as a tool to support future planning for multifunctional UGI.

Condições climáticas afetam a produtividade e a viabilidade econômica da agricultura que é desafiada pelas constantes variações de temperatura e precipitação ao longo do tempo. O objetivo deste trabalho foi estimar alterações climáticas na microrregião de Guarapuava no estado do Paraná, analisando os impactos sobre a cultura do milho, utilizando modelagem para cenários futuros e comparando com um cenário base do passado. Foram ajustados modelos de adequação matemática utilizando Análise de Múltiplos Critérios (MCA) e Processo de Hierarquia Analítica (AHP), utilizando os cenários climáticos RCP4.5 e RCP8.5 (IPCC) para o cálculo do índice de aptidão agrícola da cultura considerando as variáveis solo, topografia e clima. Concluiu-se que a projeção de aumento da temperatura média durante o ciclo de cultivo é o fator ambiental de maior impacto para a redução do índice de aptidão agrícola para o milho na microrregião de Guarapuava no ano de 2050.

Storm-water management is a common concern in rural catchments where development-related growth causes increases of storm-water flows. Greater magnitude and frequency of storm-water create greater challenges for mitigating storm-water damage and improving water quality. The concept of Blue-Green Infrastructure (BGI) as a solution incorporates a wide range of applicable components with the aim of minimizing the effect of catchment development on flow regimes without changing the watershed morphology. BGI components manage storm-water by decreasing impermeable cover and expanding natural and semi-natural systems to store water or recharge and filter storm-water into the ground. In this paper, guidelines for designing a pond as a component of BGI are provided and, configuration and size of the pond are determined. Moreover, the impacts of the designed pond on storm-water peak flow and quality are assessed for the Tarwin catchment, State of Victoria, Australia. The results indicate that the introduction of the pond would have reduced outfall inflow by 94 % and would have achieved the reduction of 88.3, 75.5 and 50.7 % for total suspended solids, total phosphorus, and total nitrogen respectively, during the extreme weather event in June 2012.

In Australia, flood risk mitigation and response has followed an ad hoc development trajectory starting largely with structural measures such as levees and later non-structural approaches such as planning and regulation. These have proved largely ineffective in reducing the exposure of towns and rural populations to flood risk and damage over time. This paper explores the possible implementation of blue-green infrastructure (BGI) approaches as a new, alternative method to reduce flood volume and rainfall runoff in regional Australia. It outlines a case study example in rural Victoria that is subject to regular and damaging floods where the possible introduction of BGI has been modelled. Different types of BGI components - bio-retention cell, rain barrel, infiltration trench, and vegetative swale - were examined and the results indicate that developing BGI systems in a regional Australian context provide multi-functional and cost-effective solutions to flooding that will support adaptation to future climate changes.

The value of using systems approaches, for situations framed as ‘super wicked’, is examined from the perspective of research managers and stakeholders in a state-based climate change adaptation (CCA) program (CliChAP). Polycentric drivers influencing the development of CCA research pre-2010 in Victoria, Australia are reflected on, using Soft Systems Methodology (SSM) to generate a boundary critique of CCA research as a human activity system. We experienced the complexity of purpose with research practices pulling in different directions, reflected on the appropriateness of agricultural bureaucracies’ historical new public management (NPM) practices, and focused on realigning management theory with emerging demands for adaptation research skills and capability. Our analysis conceptualised CliChAP as a subsystem, generating novelty in a wider system, concerned with socio-ecological co-evolution. Constraining/enabling conditions at the time dealing with political legitimacy and conceptual integration were observed as potential catalysts for innovation in research management towards better handling of uncertainty as a social process using systemic thinking in practice (StiP).

Precise information on the extent of inundated land is required for flood monitoring, relief, and protective measures. In this paper, two spectral indices, Normalized Difference Water Index (NDWI) and Modified Normalized Difference Water Index (MNDWI), were used to identify inundated areas during heavy rainfall events in the Tarwin catchment, Victoria, Australia, using Landsat-8 OLI imagery. By integrating the assessed condition of levees, this research also explains the inefficiency of the flood control measures of this region of Australia. NDWI and MNDWI indices performed well, but water features were enhanced better in the NDWI-derived image, with an accuracy of 96.04% and Kappa coefficient of 0.83.

Infection of brassica crops with the clubroot pathogen, Plasmodiophora brassicae, can result in stunted plant growth and wilting, which can severely affect crop yield. Determining P. brassicae infection within a field prior to crop planting has long posed a problem for choosing appropriate control treatments. The options for control of this pathogen are limited and in the UK and are based on adjusting pH with soil amendments. In this study quantitative polymerase chain reaction (qPCR) was investigated for measurement of this pathogen in different control treatments. The qPCR was capable of reliably quantifying P. brassicae at levels greater than and including 103 resting spores/g soil. The assay was used to study the effect of lime-based products (LimeX) on the incidence of the clubroot pathogen in field trials with broccoli crops grown on contaminated land. The results showed that variation occurred in clubroot resting spore levels in treated and untreated plots during the crop growing period. In year one there was a 96% decrease in spore load during the growth of the crop. Treatment with LimeX resulted in a greater marketable head weight of broccoli in 2 years of the field trials, and significantly reduced gall numbers on the roots in 1 year. The rate of lime (calcium carbonate) application was not found to have a significant effect in this study, however a greater reduction in clubroot was observed at higher LimeX concentrations.

Land suitability analysis is employed to evaluate the appropriateness of land for a particular purpose whilst integrating both qualitative and quantitative inputs, which can be continuous in nature. However, in agricultural modelling there is often a disregard of this contiguous aspect. Therefore, some parametric procedures for suitability analysis compartmentalise units into defined membership classes. This imposition of crisp boundaries neglects the continuous formations found throughout nature and overlooks differences and inherent uncertainties found in the modelling. This research will compare two approaches to suitability analysis over three differing methods. The primary approach will use an Analytical Hierarchy Process (AHP), while the other approach will use a Fuzzy AHP over two methods; Fitted Fuzzy AHP and Nested Fuzzy AHP. Secondary to this, each method will be assessed into how it behaves in a climate change scenario to understand and highlight the role of uncertainties in model conceptualisation and structure. Outputs and comparisons between each method, in relation to area, proportion of membership classes and spatial representation, showed that fuzzy modelling techniques detailed a more robust and continuous output. In particular the Nested Fuzzy AHP was concluded to be more pertinent, as it incorporated complex modelling techniques, as well as the initial AHP framework. Through this comparison and assessment of model behaviour, an evaluation of each methods predictive capacity and relevance for decision-making purposes in agricultural applications is gained.

Increased global demand for agricultural production is being driven, in particular, by the rising middle class in the Asia-Pacific geo-region. The significant role of natural resource-based industries, especially agriculture, in the development of non-metropolitan regions is again being recognised. In this context, this article describes a spatial analysis approach to agricultural development based on the development of Production Areas (PAs) in regional/rural economies. PAs are spatial units within regions selected for the intensive sustainable development of agriculture (including forestry, agro-forestry and bio-energy), their associated activities and underpinning infrastructure. A case study in a resource-based region in Australia—Gippsland – explains the approach. This is informed by the eco-economy model of endogenous regional/rural development, which addresses the links between novel co-production and consumption networks. The methodology for the identification and analysis of PAs has, at its core, Land Suitability Analyses of those agricultural commodities currently cultivated in the region and those that could be grown in future climates. The use of GIS enables us to overlay and analyse several constraints (e.g. flood erosion and salinity risk) and resources (e.g. water and transport) to define PAs and the available land within each of them. The approach is further illustrated by focusing in one PA—Macalister, an irrigated dairy production area where recent dry climatic conditions caused a substantial decline in water resources. Key elements for the sustainable development of this PA are outlined including construction of Blue-Green Infrastructure. Comments on the approach and the need for strategic long-term planning concludes the article.

In 2008, vegetable growers observed stunted lettuce plants showing signs of chlorosis and wilting. It was suspected that monochloramine in the recycled water used for irrigation, in combination with extreme environmental conditions (high irrigation water salinity and extreme heat), was responsible for these crop failures. A series of glasshouse studies was conducted to evaluate the impact of monochloramine concentration alone on iceberg lettuce seedlings, as well as in combination with high salinity and hot ambient temperatures. Monochloramine concentrations up to 9 and 15 mg L−1 Cl2 for continuous and initial irrigation only, respectively, did not affect the weight of iceberg lettuce heads (p > 0.05), while the combination of monochloramine (4–5 mg L−1 Cl2) and salinity (3,500 μS cm−1) did not significantly affect harvest measurements (p > 0.05). We therefore conclude that it is unlikely that monochloramine was responsible for the observed crop failures.

Australian agriculture is very susceptible to the adverse impacts of climate change, with major shifts in temperature and rainfall projected. In this context, this paper describes a research methodology for assessing potential climate change impacts on, and formulating adaptation options for, agriculture at regional level. The methodology was developed and applied in the analysis of climate change impacts on key horticultural commodities—pome fruits (apples and pears), stone fruits (peaches and nectarines) and wine grapes—in the Goulburn Broken catchment management region, State of Victoria, Australia. Core components of the methodology are mathematical models that enable to spatially represent the degree of biophysical land suitability for the growth of agricultural commodities in the region of interest given current and future climatic conditions. The methodology provides a sound analytic approach to 1) recognise regions under threat of declines in agricultural production due to unfolding climatic changes; 2) identify alternative agricultural systems better adapted to likely future climatic conditions and 3) investigate incremental and transformational adaptation actions to improve the problem situations that are being created by climate change

Options for the integrated management of white blister (caused by Albugo candida) of Brassica crops include the use of well timed overhead irrigation, resistant cultivars, programs of weekly fungicide sprays or strategic fungicide applications based on the disease risk prediction model, Brassicaspot™. Initial systematic surveys of radish producers near Melbourne, Victoria, indicated that crops irrigated overhead in the morning (0800–1200 h) had a lower incidence of white blister than those irrigated overhead in the evening (2000–2400 h). A field trial was conducted from July to November 2008 on a broccoli crop located west of Melbourne to determine the efficacy and economics of different practices used for white blister control, modifying irrigation timing, growing a resistant cultivar and timing spray applications based on Brassicaspot™. Growing the resistant cultivar, ‘Tyson’, instead of the susceptible cultivar, ‘Ironman’, reduced disease incidence on broccoli heads by 99 %. Overhead irrigation at 0400 h instead of 2000 h reduced disease incidence by 58 %. A weekly spray program or a spray regime based on either of two versions of the Brassicaspot™ model provided similar disease control and reduced disease incidence by 72 to 83 %. However, use of the Brassicaspot™ models greatly reduced the number of sprays required for control from 14 to one or two. An economic analysis showed that growing the more resistant cultivar increased farm profit per ha by 12 %, choosing morning irrigation by 3 % and using the disease risk predictive models compared with weekly sprays by 15 %. The disease risk predictive models were 4 % more profitable than the unsprayed control.

The potato cyst nematodes (PCN), Globodera rostochiensis (Woll.) and G. pallida (Stone), are major pests of ware and seed potato (Solanum tuberosum L.) crops worldwide and severely impact the movement of potatoes around the globe through quarantine restrictions. In Australia, only G. rostochiensis has been discovered, on four separate occasions between 1986 and 2008. The infested areas are the subject of strict regulation and quarantine procedures and while they are considered to be contained, managing nematode populations remains a priority. This study has identified the G. rostochiensis Ro1 resistance-status of potato cultivars currently grown by Australian potato growers, and new cultivars emerging from the Australian Potato Breeding Program. Resistance was assessed by a simple and robust procedure carried out in a purpose-built quarantine facility. Of the 24 potato cultivars grown in the affected Koo Wee Rup district in 2004, 10 were resistant to nematode infestation, including the locally important cultivar Atlantic. Other cultivars important to the Victorian and Australian potato industry, such as Kennebec, Desiree, Sebago and Coliban, were classified as susceptible. Importantly, this study provided evidence that the Koo Wee Rup PCN population was able to complete its lifecycle on the native plant species, S. aviculare (kangaroo apple), potentially acting as an alternate host and spreading PCN among potato crops.

Purpose – This paper seeks to scope the nature and form of practices, understandings and institutional arrangements that might contribute to the successful “design” and continuity of Communities of Practice (CoP) in a state government department in Australia. The study aims to provide research evidence to support the design and establishment of a CoP based on systems thinking within this department.Design/methodology/approach – A total of 13 semi-structured interviews were undertaken involving 14 informants. The interviewer also attended one CoP meeting. An emergent approach to research design was adopted with data analysis guided by previous studies on CoPs.Findings – The research revealed the existence of six CoPs that were purposefully created internally by the department. Six “design” and practice considerations were suggested for practitioners aiming to create and sustain successful CoPs.Research limitations/implications – Interview material was the only source of primary data and it was gathered from one organisation only – a state government department in Australia. Findings indicate that the role of the CoP coordinator is still not fully understood.Practical implications – The results from this study can be used in re-designing a systems thinking CoP to support systems thinking within the department. The study also revealed that purposefully designing CoPs is possible and useful for practitioners aiming to collaborate and share expertise across disciplinary and divisional boundaries.Originality/value – This study provides some guidance for the purposeful design of CoPs, which has been under-examined in the literature.

Microarray analysis was used to investigate changes in host gene expression during the primary stages of the interaction between the susceptible plant Arabidopsis thaliana (L.) Heynh ecotype Col-0 and the biotrophic pathogen Plasmodiophora brassicae Woronin. Analyses were conducted at 4, 7 and 10 days after inoculation (DAI) and revealed significant induction or suppression of a relatively low number of genes in a range of functional categories. At 4 DAI, there was induced expression of several genes known to be critical for pathogen recognition and signal transduction in other resistant host–pathogen interactions. As the pathogen further colonised root tissue and progressed through the primary plasmodium stage to production of zoosporangia at 7 and 10 DAI, respectively, fewer genes showed changes in expression. The microarray results were validated by examining a subset of induced genes at 4 DAI by quantitative real-time reverse transcriptase PCR (RT-qPCR) analysis all of which correlated positively with the microarray data. The two A. thaliana mutants jar1 and coiI tested were found to be susceptible to P. brassicae. The involvement of defence-related hormones in the interaction was further investigated and the findings indicate that addition of salicylic acid can suppress clubroot disease in A. thaliana plants.

The purpose of this study was to investigate the occurrence of antibiotic resistance genes (ARGs) in water used for irrigation in the Werribee River Basin, Australia, including river water and reclaimed effluent water (reclaimed water). Samples of reclaimed water, collected over a one-year period, were screened for the occurrence of ARGs using PCR detection assays. The presence of ARGs in the reclaimed water samples were contrasted with that of water samples taken from the Werribee River Basin, collected over the same time period, from five points selected for varying levels of urban and agricultural impact. Of the 54 river water samples collected, 2 (4%), 2 (4%), 0 and 0 were positive for methicillin, sulfonamide, gentamicin and vancomycin-resistant genes, respectively, while 6 of 11 reclaimed water samples were positive for methicillin (9%) and sulfonamide (45%). The presence/absence of ARGs did not appear to correlate with other measured water quality parameters. The low detection of ARGs in river water indicates that, regardless of its poor quality, the river has not yet been severely contaminated with ARGs. The greater prevalence of ARGs in reclaimed water indicates that this important agricultural water source will need to be monitored into the future.
