    This report identifies major constraints to the adaptive capacity of food organisations operating in Australia. This report is about food security, climate change and risk management. Australia has enjoyed an unprecedented level of food security for more than half a century, but there are new uncertainties emerging and it would be unrealistic – if not complacent – to assume the same level of food security will persist simply because of recent history. The project collected data from more than 36 case study organisations (both foreign and local) operating in the Australian food-supply chain, and found that for many businesses,  risk management practices require substantial improvement to cope with and exploit the uncertainties that lie ahead. Three risks were identified as major constraints to adaptive capacity of food organisations operating in Australia:  risk management practices; an uncertain regulatory environment – itself a result of gaps in risk management; climate change uncertainty and projections about climate change impacts, also related to risk management

    How multilevel societal learning processes facilitate transformative change: A comparative case study analysis on flood management

    Get PDF
    Sustainable resources management requires a major transformation of existing resource governance and management systems. These have evolved over a long time under an unsustainable management paradigm, e.g., the transformation from the traditionally prevailing technocratic flood protection toward the holistic integrated flood management approach. We analyzed such transformative changes using three case studies in Europe with a long history of severe flooding: the Hungarian Tisza and the German and Dutch Rhine. A framework based on societal learning and on an evolutionary understanding of societal change was applied to identify drivers and barriers for change. Results confirmed the importance of informal learning and actor networks and their connection to formal policy processes. Enhancing a society's capacity to adapt is a long-term process that evolves over decades, and in this case, was punctuated by disastrous flood events that promoted windows of opportunity for change

    Extraordinarily Prolonged Disease Recurrence in a Granulosa Cell Tumor Patient

    Background: Granulosa cell tumors are rare sex cord stromal lesions that comprise approximately 3% of all ovarian neoplasms. The vast majority of granulosa cell tumors are considered indolent but in spite of aggressive management, delayed recurrence is of significant concern. Case Report: We describe a case involving a 67-year-old woman who presented with abdominal pain, bloody stools, and mild nausea. Following a CT scan of the abdomen and pelvis, a 19-cm pelvic mass was identified. Her prior medical history included a hysterectomy for uterine fibroids 40 years ago and a bilateral salpingo-oophorectomy for a presumed granulosa cell tumor 20 years ago. Final pathology revealed granulosa cell tumor with small bowel mesentery involvement. The patient underwent surgical resection and adjuvant chemotherapy; she is currently doing well. Conclusion: Granulosa cell tumors are considered to be of low malignant potential but they have the capacity to recur, even several years following initial patient management. This case exemplifies the disease’s capacity for prolonged recurrence and further accentuates the significance of long-term follow-up in these patients

    Reenergising professional creativity from a CHAT perspective: Seeing knowledge and history in practice

    Get PDF
    This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2011 Regents of the University of California.This article offers a critical examination of aspects of a practice- and theory-developing intervention in the teacher education setting in England designed as a variation of Developmental Work Research. A positive case is argued for the distinctiveness of such cultural-historical activity theory [CHAT-] informed interventions and some points of contrast are drawn with the British tradition of educational action research. In describing the practice-developing intervention, the twin focus on seeing knowledge and history in human activity systems is advanced as two dimensions of CHAT's distinctive approach, with the goal of stimulating and studying the emergence of professional creativity. Creativity under this interpretation is defined as the perception and analysis of opportunities for learning within the social situation of development and the production of new conceptual tools and approaches to the social organisation of work. Professional creativity is advanced as a much needed capacity among teachers in industrial workplaces influenced by the techniques of New Public Management. Common ground between CHAT and action research approaches is seen in their optimistic and modernist commitments to progress, and CHAT-framed interventions, like action research approaches, are presented as part of an evolving intellectual project

    Water Demand, Adaptive Capacity, and Drought: an Analysis of the Upper Klamath Basin, Oregon and California

    Get PDF
    Freshwater demand and scarcity issues are an issue of global concern, in particular for the American West as global climate models suggest precipitation regime changes and an increase of drought. This research conducts a case-study of the Upper Klamath Basin, located in south-central Oregon and northern California, a microcosm of the arid and semi-arid American West that experienced an economically, socially, and ecologically impactful drought in the early 2000s. Through a mixture of qualitative and quantitative methods this research: 1) identifies key stakeholders, their goals and key policies; 2) conducts an adaptive capacity assessment of water management within the basin; and 3) makes future recommendations for water policy and management within the basin. To achieve these objectives content analysis, semi-structured interviews, and an event history calendar were completed. Results indicate that adaptive capacity is tied, in addition to occurrences of drought, to events on the sociopolitical landscape and is variable to each stakeholder group examined. This research shows that adaptive capacity overall was on the rise following the early 2000s, peaking with the signing of the Klamath Basin Restoration Agreement (KBRA) and Final Order of Determination but has begun decreasing again following the sunset of the KBRA in 2015

    Africa's COVID-19 Situation in Focus and Recent Happenings: A Mini Review.

    Full text link
    Given that COVID-19 (SARS-CoV-2) has crept into Africa, a major public health crisis or threat continues to linger on the continent. Many local governments and various stakeholders have stepped up efforts for early detection and management of COVID-19. This mini review highlights the current trend in Africa, history and general epidemiological information on the virus. Current ongoing efforts (e.g., improving testing capacity) and some effective ways (e.g., intensified surveillance, quick detection, contact tracing, isolation measures [e.g., quarantine], and social distancing) of preventing and managing COVID-19 in Africa are described. The review concludes by emphasizing the need for public health infrastructure development (e.g., laboratories, infectious disease centers, regional hospitals) and human capacity building for combating COVID-19 and potential future outbreaks. Additionally, regular public health educational campaigns are urgently required. Future epidemiological studies to ascertain case fatality and mortality trends across the continent for policy directions are necessary

    Optimising invasive fish management in the context of invasive species legislation in South Africa

    Get PDF
    South Africa hosts a large number of non-native freshwater fishes that were introduced for various industries. Many of these species are now listed under the National Environmental Management: Biodiversity Act (NEM:BA) Alien and Invasive Species (A&IS) lists and regulations, though the practical options available to conservation agencies to effectively manage these fishes vary greatly among species and regions. Objectives & methods: We assessed the history and status of national legislation pertaining to invasive freshwater fishes, and the practical implications of the legislation for managing different species with contrasting distributions, impacts and utilisation value. Results: The smallmouth bass, despite being a potential conflict-generating species, is fairly straightforward to manage based on current legislation. Two species of trout, which remain absent from the NEM:BA A&IS lists because of ongoing consultation with stakeholders, continue to be managed in regions like the Western Cape province using existing provincial legislation. To maximise the limited capacity for management within conservation agencies, we proposed a decision-support tool that prioritises invasive fish populations that represent high environmental risk and low potential for conflict with stakeholders. Using three case studies, we demonstrated how the tool can be used to set management goals of 'eradicate', 'manage against impacts and further spread' and 'continue to monitor population' as the most pragmatic solutions given the state of an invasion, its socio-economic impact and the capacity of the responsible agency to act. Conclusion: By choosing a pragmatic management strategy, conservation agencies can maximise the effective deployment of limited resources, while minimising avoidable conflicts with stakeholders.EM201

    Cooperative Federalism in Biscayne National Park

    Get PDF
    Biscayne National Park is the largest marine national park in the United States. It contains four distinct ecosystems, encompasses 173,000 acres (only five percent of which are land), and is located within densely populated Miami-Dade County. The bay has a rich history of natural resource utilization, but aggressive residential and industrial development schemes prompted Congress to create Biscayne National Monument in 1968, followed by the designation of Biscayne National Park in 1980. When the dust settled, Florida retained key management powers over the Park, including joint authority over fishery management. States and the federal government occasionally share responsibility for regulating natural resources, but Biscayne National Park represents a unique case study in cooperative federalism. This article explores these cooperative federalism contours in order to assess whether the park’s management paradigm provides a model worthy of replication. A diverse range of materials were reviewed for this project, including literature and jurisprudence on traditional models of cooperative federalism, federal natural resources laws, national park regulations and policy, Biscayne National Park’s statutory frameworks and legislative history, state and federal management plans, inter-agency communications, and direct stakeholder interviews. These materials combine to tell a story of cooperative federalism that has been frustrating and, at times, incoherent. But the story also demonstrates that shared responsibility over fishery management has produced beneficial results for the Park and its stakeholders by forcing state and federal officials to work together on planning and enforcement, diversifying human and financial resources, and incorporating federal, state, and local interests into park management and policy. The research suggests that future applications of the Biscayne National Park model of cooperative federalism, in which states and the federal government share joint authority over marine resources in some capacity, may enjoy similar success

    Peritoneal carcinomatosis from a small bowel carcinoid tumour

    Get PDF
    BACKGROUND: Peritoneal carcinomatosis from a gastrointestinal carcinoid tumour is rare and the long-term management and prognosis have not been clearly defined. The natural history is different from gastrointestinal adenocarcinoma, although its capacity to invade regional lymph nodes and generate distal metastasis can make the management more complex. Whilst the development of carcinomatosis is uncommonly reported, it may be higher than expected. CASE PRESENTATION: A 63 years-old woman underwent emergency surgery in 1993 for right iliac fossa pain and a mass that was found to be an ileal carcinoid tumour. Over the next ten years, further surgery was required for disseminated disease with peritoneal carcinomatosis and liver metastasis. Systemic chemotherapy had little effect, although Somatostatin was used effectively to relieve symptoms caused by the disseminated disease (flushing and diarrhoea). CONCLUSION: Peritoneal carcinomatosis from carcinoid tumours is not well documented in the literature. Aggressive surgery must be performed in order to control the disease since chemotherapy has not been reported to be effective. With repeated surgery long-term survival can be achieved in these patients
