Future landscapes in South-eastern Australia : the role of protected areas and biolinks in adaptation to climate change

The extent and rapidity of global climate change is the major novel threatening process to biodiversity in the 21 st century. Globally, numerous studies suggest movement of biota to higher latitudes and altitudes with increasing empirical -evidence emerging. As biota responds to the direct and consequent effects of climate change the potential to profoundly affect natural systems (including the reserve system) of south-eastern Australia is becoming evident. Climate change is projected to accelerate major environmental drivers such as drought, fire and flood regimes. Is the reserve system sufficient for biodiversity conservation under a changing climate? Australia is topographically flat, biologically mega-diverse with high species endemism, and has the driest and most variable climate of any inhabited continent. Whilst the north-south orientation and aftitude gradient of eastern Australia's forests and woodlands provides some resilience to projected climatic change, this has been eroded since European settlement, particularly in the cool-moist Bassian zone of the south-east. Following settlement, massive land-use change for agriculture and forestry caused widespread loss and fragmentation of habitats; becoming geriatric in agricultural landscapes and artificially young in forests. The reserve system persists as an archipelago of ecological islands surrounded by land uses of varying compatibility with conservation and vulnerable to global warming. The capacity for biota to adapt is limited by habitat availability. The extinction risk is exacerbated. Re-examination of earlier analysis of ecological connectivity through biolink zones confirms biolinks as an appropriate risk management response within a broader suite of measures. Areas not currently in the reserve system may be critical to the value and ecological function of biological assets of the reserve system as these assets change. Ecological need and the rise of ecosystem services, combined with changing socio-economic drivers of land-use and social values that supported the expansion of the reserve system, all suggest biolink zones represent a new, necessary and viable multi-functional landscape. This paper explores some of the key ecological elements for restoration within biolink zones (and landscapes at large) particularly through currently agricultural landscapes.

Learning in agriculture : building social capital in island communities

Social capital helps communities respond positively to change. Research in agricultural businesses and into managing change through learning in communities has highlighted the importance of relationships between people and the formal and informal infrastructure of communities to the quality of outcomes experienced by communities, businesses and individuals. Communities can be geographic communities - the data drawn on in this paper are from an island community, for example or communities-of-common-purpose, such as agricultural organisations. This paper reviews research into managing change through learning and social capital, presents a model of the simultaneous building and use of social capital and explores the ways in which learning as part of an agricultural community can be used to bring benefits to geographic communities such as islands. The model presented in this paper stems from studies of the informal learning process that builds resilient communities. It conceptualises the way in which social capital is used and built in interactions between individuals. There are two stages to the model. The first stage depicts social capital at the micro level of one-on-one interactions where it is built and used. The second stage of the model is about the interrelationship of micro-level social capital processes with the community and societal-level social capital resources.

History of contact and change in the Goroka Valley, Central Highlands of New Guinea, 1934-1949

The thesis traces the interaction of the Goroka Valley people with European and coastal New Guinean intruders during the pacification stage of contact and change. In this 15 year period the people moved from a traditional subsistence culture to the threshold of a modern, European-influenced technological society. The contact experiences of the inhabitants of the Valley and the outsiders who influenced them are examined, using both oral and documentary sources. A central theme of this study is the attempts by Europeans and their coastal New Guinean collaborators to achieve the pacification of a people for whom warfare has been described as 'the dominant orientation'. The newcomers saw pacification as being inextricably linked with social, economic and religious transformation, and consequently it was pursued by patrol officers, missionaries and soldiers alike. Following an introductory chapter outlining the pre-contact and early-contact history of the Goroka Valley people, there is a discussion of the causes of tribal fighting in Highlands communities and two case studies of violent events which, although occurring beyond the Goroka Valley, had important consequences for those who lived within its bounds. The focus then shifts to the first permanent settlement of the agents of change -initially these were coastal New Guinean evangelists and policemen - and their impact on the local people. A period of consolidation is then described, as both government and missions established a permanent 'European presence in the Valley'. This period was characterised by vigorous pacification coupled with the introduction of innovations in health and education, agriculture, technology, law and religion. The gradual transformation of Goroka Valley society as a result of the people's interaction with the newcomers was abruptly accelerated in 1943, when many hundreds of Allied soldiers occupied the Valley in anticipation of a threatened Japanese invasion. Village life was disrupted as men were conscripted as carriers and labourers and whole communities were obliged to grow food to assist the Allied war effort. Those living close to military airfields-and camps were subject to Japanese aerial attacks and the entire population was exposed to an epidemic of bacillary dysentery introduced by the combatants. However the War also brought some positive effects, including paradoxically, the almost total cessation of tribal fighting, the construction of an ail-weather airstrip at Goroka which ensured its future as a town and administrative and commercial centre, and the compulsory growing of vegetables, coffee, etc, which laid the foundations for a cash economy and material prosperity. The final chapter examines the aftermath of military occupation, the return of civil administration and the implementation of social and economic policies which brought the Goroka Valley people into the rapid-development phase of contact. By 1949 Gorokans were ready to channel their aggressive energies into commercial competitiveness and adopt a cash-crop economy, to accept the European rule of law, to take advantage of Western innovations in medicine, education, transport and communications, to seek employment opportunities at home and in other parts of the country and to modify their primal world view with European religious and secular values. A Stone Age people was in process of being transformed into a modern society.

Perpetual revolution : people and state in socialist Cuba

This thesis examines the definition of “Revolution” in Cuba, exploring the political and social system that is associated with what people in Cuba call “the Revolution”, and placing special emphasis on people’s daily experiences of such systems. Through an analysis of organic movements of urban agriculture, alternative therapies emerging within the framework of a state-centred biomedical health system, and emigration this thesis aims to understand the lived experience of the Cuban Revolution

Nation-building across the urban and rural in Timor-Leste : conference report

‘Nation-building across Urban and Rural Timor-Leste’ provided an opportunity for East Timorese and people from around the world to reflect, discuss and debate the nation-building process in Timor-Leste since 1999. In this context, nation-building in Timor-Leste is taken to mean the many different attempts since 1999 to ensure the political, economic and cultural integration of the population to fulfil the ambition of self rule.

Ten years after the 1999 vote for independence, this conference considered how nation-building is being experienced and responded to across urban and rural communities in Timor-Leste. Broadening the discussion beyond that of ‘state-building’, at the core of the conference was a consideration of the myriad ways the new republic has been ‘built’. Here ‘nation-building’ considers not only in terms of policy and programmatic initiatives but also grass roots experiences and perceptions of how Timor-Leste as a nation is seen and understood. For this reason, the majority of participants were East Timorese representatives from across the districts, allowing them top share their stories of nation-building.

Expert systems modeling for assessing climate change impacts and adaptation in agricultural systems at regional level

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.

Effects of site of assessment and variation in wool quality traits on the tactile assessment of textural greasy wool handle

Variation in textural greasy wool handle across the fleece of Merino sheep was explored. Results demonstrate that there were significant differences across nine sites on the fleece. The inclusion of the covariates fibre diameter, fibre diameter co-efficient of variation, staple length, dust penetration, staple structure, greasy wool colour and resistance to compression, helped to explain some of the variation in textural greasy wool handle between sites such that site of assessment was no longer a significant factor (P ≤ 0.065). However, in practice, those involved with clip preparation or sheep selection based on textural greasy wool handle assessment are unlikely to have these measurements available. The results highlight the importance of nominating a site of assessment when recording textural greasy wool handle. © CSIRO 2014.

Opportunities and challenges in developing a whole-of-government national food and nutrition policy: lessons from Australia's National Food Plan

OBJECTIVE: The present article tracks the development of the Australian National Food Plan as a 'whole of government' food policy that aimed to integrate elements of nutrition and sustainability alongside economic objectives. DESIGN: The article uses policy analysis to explore the processes of consultation and stakeholder involvement in the development of the National Food Plan, focusing on actors from the sectors of industry, civil society and government. Existing documentation and submissions to the Plan were used as data sources. Models of health policy analysis and policy streams were employed to analyse policy development processes. SETTING: Australia. SUBJECTS: Australian food policy stakeholders. RESULTS: The development of the Plan was influenced by powerful industry groups and stakeholder engagement by the lead ministry favoured the involvement of actors representing the food and agriculture industries. Public health nutrition and civil society relied on traditional methods of policy influence, and the public health nutrition movement failed to develop a unified cross-sector alliance, while the private sector engaged in different ways and presented a united front. The National Food Plan failed to deliver an integrated food policy for Australia. Nutrition and sustainability were effectively sidelined due to the focus on global food production and positioning Australia as a food 'superpower' that could take advantage of the anticipated 'dining boom' as incomes rose in the Asia-Pacific region. CONCLUSIONS: New forms of industry influence are emerging in the food policy arena and public health nutrition will need to adopt new approaches to influencing public policy.

The effect of repeated boar exposure on cortisol secretion and reproduction in gilts

It has been proposed that short-term activation of the hypothalamo-pituitary adrenal axis, with a consequent increase in the secretion of cortisol, amy disrupt the endocrine events prior to ovulation and thereby impair reproduction in females. We investigated this concept in gilts in which oestrus was detected by introduction to boars, where intense physical contact is possible, or by applying pressure to the back of gilts (back-pressure test) during fence-line exposure to boars, where intense physical contact is prohibited. We expected that there would be a greater release of cortisol and that reproduction would be inhibited in gilts introduced to boars compared to gilts in which the back-pressure test was used. As expected, introduction of gilts to boars resulted in a significant transient increase in plasma concentrations of cortisol while there was no significant effect of using the back-pressure test on plasma cortisol. Nevertheless, introduction of gilts to boars did not impair reproduction and there was no effect of method of detecting oestrus on duration of oestrus, sexual receptivity, fertility or fecundity. The length of the oestrous cycle was decreased and ovulation rate increased in gilts that were introduced to boars compared to gilts that underwent the back-pressure test, indicating that introduction of gilts to boars may have stimulated these aspects of reproduction. These stimulatory effects may have been due to an increased exposure of gilts to sexual behaviour and stimuli from boars when introduced to boars and/or to stimulatory effects of the hypothalamo-pituitary adrenal axis on some aspects of reproduction.
