Academic literature on the topic 'Murrumbateman'

Tillage experiments with wheat (Triticum aestivum L.) were conducted at 2 sites in south-eastern Australia: one cool and wet (Murrumbateman), the other warmer and drier (Yanco). Following crop residue removal, direct drilling treatments with complete surface disturbance to 3 cm depth of the medium-textured topsoils (D), or with disturbance only in the narrow seeding slots (DN), were compared with drilling into a surface prepared by cultivating to about 7 cm depth (control). At the 4.5 leaf stage, seedlings from D and DN treatments had less shoot dry weight than the control except at Murrumbateman under very wet post-seeding conditions. Simulation of the above tillage treatments in intact soil Cores from both sites kept under controlled temperature and moisture conditions confirmed that DN treatment, with only 11% of the volume of soil disturbance of the control, reduced early growth, especially at Yanco and if post-sowing conditions were drier. Reduced shoot growth was associated with relatively larger effects on the extent of root exploration. Treatment D, with 43% of the volume of disturbed soil, did not reduce shoot growth relative to the control under any circumstances. Although results suggest a minimum volume of disturbed soil for maximum growth, interactions with biotic stresses as reported recently cannot be ruled out.

Soil temperatures were measured at different depths under wheat crops sown by three different methods in a dry (1982) and a wet season (1983). A conventionally cultivated treatment, which comprised a short cultivated fallow, was compared with one which was directly drilled with full disturbance of the soil surface after previous crop residues had been burned, and with another treatment which was directly drilled with minimum disturbance into soil carrying 2-4 t ha-' stubble. Generally the soil temperatures at any particular depth of the conventionally cultivated treatment were warmer during the day and cooler during the night than the soil temperatures at the same depth in the direct drilled treatments. These patterns persisted throughout both the growing seasons, but in the wet year (1983) there was little difference between temperatures under conventional cultivation and direct drill with stubble burning and full disturbance. Similar temperature patterns were measured when the same treatments were imposed on an adjacent area which had previously been growing fertilized ryegrass/clover pasture. It was found that wheat sown by conventional means had a larger shoot dry weight per plant at the 4 1/2 leaf stage of development than direct drilled wheat. The improved early vigour of wheat sown by conventional cultivation practices could at least partially have been due to the patterns in soil temperature.

This thesis is an evaluation of the use the USLE to estimate soil loss from two pastoral land uses - commercial properties and "hobby farms" in Murrumbateman. Sensitivity analysis was used to evaluate the USLE components. Sediment measurement in farm dams was taken to estimate sediment yield from several sites, as an alternative approach to study soil loss. The annual soil loss from entire study area was 0.25 t/ha/year whilst these figures from commercial properties and hobby farms were 0.29 t/ha/year and 0.21 t/ha/year, respectively. The annual average sediment yield from three catchments in hobby farms was 0.3 t/ha/year. The USLE was found to be highly sensitive to slope steepness, ground cover and stocking rates. The critical values were 16% for slopes, 35% for the ground cover and 19 Dry Sheep Equivalent/ha for stocking rate. I tentatively conclude that the USLE is sufficiently sensitive to detect differences in soil loss between the two land uses. There is, however, a need to improve the operation of the model in some respects. The use of farm dams for estimating sediment yield also shows promise.

This thesis contends that; in mainstream rural residential development around the Australian Capital Territory, use of community title guidelines for sub-division should consider social processes and environmental considerations along-side economic imperatives and interactions. Community title is a form of land tenure that allows for private freehold ownership of land as well as community owned land within the one sub-division. In New South Wales, community title was introduced in 1990 under the Community Land Development Act 1989 (NSW) and the Community Land Management Act 1989 (NSW). Since the introduction of community title, upwards of one hundred and fifty developments, ranging from just a few blocks to the size of small suburbs, have been approved throughout the state. The original aim of community title was to provide a legal framework that underpinned theme-based broad-acre development. Themebased development could include a Permaculture© village, a rural retreat for likeminded equine enthusiasts, or even a medieval village. Community title is also seen as an expedient form of land tenure for both developers and shire councils. Under community title, a developer only has to submit a single development application for a multi-stage development. This can significantly reduce a developer's exposure to risk. From a shire council's perspective, common land and resources within a development, which would otherwise revert to council responsibility for management, becomes the collective responsibility of all the land owners within the development, effectively obviating council from any responsibility for management of that land. Community title is also being touted in planning and policy as a way of achieving 'sustainable' environmental management in new subdivisions. The apparent expediency of community title has meant that development under these guidelines has very quickly moved beyond theme-based development into mainstream rural residential development. Community title effectively provides a framework for participatory governance of these developments. The rules governing a community title development are set out in the management statement, which is submitted to the local council and the state government with the development application. A community association, which includes all lot owners, manages the development. Unless written into the original development application, the council has no role in the management of the common land and resources. This thesis looks at the peri-urban zone around one of Australia's fastest growing cities - Canberra, whose population growth and relative affluence is impacting on rural residential activity in the shires surrounding the Australian Capital Territory. Yarrowlumla Shire, immediately adjacent to the ACT, has experienced a 362 percent increase in population since 1971. Much of this growth has been in the form of rural residential or hobby farm development. Since 1990, about fifteen percent of the development in Yarrowlumla Shire has been community title. The Yass Shire, to the north of the ACT, has shown a forty five percent population increase since 1971. Community title in that shire has accounted for over fifty percent of development since 1990. The thesis case study is set in Yass Shire. The major research question addressed in the thesis is; does community title, within the context of rural residential development around the Australian Capital Territory, facilitate community-based environmental management and education? Subsidiary questions are; what are the issues in and around rural residential developments within the context of the study, who are the stakeholders and what role do they play and; what skills and support are required to facilitate community-based environmental management and education within the context of the study area? To answer the research questions I undertook an interpretive case study, using ethnographic methods, of rural residential development near the village of Murrumbateman in the Yass Shire, thirty kilometres north of Canberra. At the time of the study, which was undertaken in 1996, the developments involved had been established for about four years. The case study revealed that, as a result of stakeholders and residents not being prepared for the management implications of community title, un-necessary conflict was created between residents and between residents and stakeholders. Community-based environmental management issues were not considered until these issues of conflict were addressed and residents had spent enough time in the estates to familiarise themselves with their environment and with each other. Once residents realised that decisions made by the community association could affect them, there developed a desire to participate in the process of management. Eventually, earlier obstacles were overcome and a sense of community began to develop through involvement in the community association. As residents became more involved, the benefits of having ownership of the community association began to emerge. However, this research found that management of a broad acre rural residential development under community title was far more complicated than any of the stakeholders, or any but the most legally minded residents, were prepared for.
