The soil moisture characteristics of undisturbed samples of Mallee soils, taken from typical profiles of the Riverland district neat Berri in South Australia, were determined. Samples were grouped according to texture and bulk density and, for each group, the moisture storage between matric potentials was derived. Over the usual range of soil moisture tensions (-0 to 40kPa) these showed only small variation between soil groups since, while moisture storage at field capacity and at wilting point does vary with texture; 50 to 60 mm/m is available between field capacity (-7 kPa) and the re-irrigation point (-30 to 40kPa) in all soils.

The soil structural conditions of two management systems of vineyard soil on Barmera Sandy Loam in the Riverland of South Australia were compared. Three years of zero cultivation and weed mulching were compared with long term winter cropping and cultivation between vines. Significant increases in 1 mm dry aggregates, aggregate stability and percentage of large pores were measured under zero tillage. Significant reductions also occurred for bulk density and penetration resistance of the 6-12 cm layer of the zero-tilled soil. The results suggest that infiltration, aeration and root growth of vines would improve under a long-term program of zero tillage and weed mulching.

SUMMARYRoss River virus (RRV) infection is the most common notifiable vector-borne disease in Australia, with around 6000 cases annually. This study aimed to examine the relationship between climate variability and notified RRV infections in the Riverland region of South Australia in order to set up an early warning system for the disease in temperate-climate regions. Notified data of RRV infections were collected by the South Australian Department of Health. Climatic variables and monthly river flow were provided by the Australian Bureau of Meteorology and South Australian Department of Water, Land and Biodiversity Conservation over the period 1992–2004. Spearman correlation and time-series-adjusted Poisson regression analysis were performed. The results indicate that increases in monthly mean minimum and maximum temperatures, monthly total rainfall, monthly mean Southern Oscillation Index and monthly flow in the Murray River increase the likelihood, but an increase in monthly mean relative humidity decreases the likelihood, of disease transmission in the region, with different time-lag effects. This study demonstrates that a useful early warning system can be developed for local regions based on the statistical analysis of readily available climate data. These early warning systems can be utilized by local public health authorities to develop disease prevention and control activities.

The Riverland Ramsar site in south-eastern Australia has Limits of Acceptable Change (LAC) derived on the basis of hydrological regimes and vegetation requirements. This study evaluated LAC for the site against trajectories of environmental change including increasing river regulation and changing climate. The study identified a high likelihood of exceedances of the LAC from changed hydrologic regime and also from changing climate, with the combined influences increasing the likelihood of breaches. Regional climatic variations in the past call into question the concept of baseline conditions for this site and elsewhere, and suggest that management plans based on ecological variation around a point in time will be insufficient. Vulnerability assessment, adaptation enhancement, and regular reviews of site condition and regional significance are suggested components for future management of Ramsar sites.

AbstractNancy Cato (1917–2000) was born in Adelaide and lived there for the first half of her life. Moving to Noosa in 1967, she became known for environmental activism as well as her writing. Through research for her historical novels set in Tasmania and on the Murray River, as well as her travels in Central and Northern Australia, she developed a strong interest in Aboriginal and Torres Strait Islander peoples. She published poetry, stories, plays and journalism, as well as novels set in the Northern Territory, North Queensland, the Riverland and Tasmania. She had a painter's eye as well as a gift for lyrics and a lifelong interest in storytelling. With the emergence of eco-criticism, we can now see her diverse career as a writer as cohering around her love of the natural world and her curiosity about how human beings lived in it. This article considers her writing about her adopted country around Noosa.

Abstract A sand-box experiment equipment is constructed to simulate the transportation of contaminant in unsaturated flow under dirichlet boundary condition. Based on analysis of the mechanism in unsaturated migration, taking a riverland as an example, the model of water quality which was affected by contaminant transport was built, and the calculation values coincided well with experimental data. The results showed that the lateral migration should not be neglected when seepage velocity was high. In addition, the lateral migration was faster in high moisture content areas and the solute was retained for a short time; however, the situation was reversed in low moisture content areas. Moreover, during the initial stage of solute transport, the velocity of the trailing end of the pinnate pollution zone was high under the effect of capillary action, which would lead to expansion of the range of pollution. Furthermore, the relative concentration curve of pollutants presented a single peak state, with the peak value of the curve increasing with the velocity, and the arrival time of the peak value was also gradually advanced. Therefore, this study can provide reference for the prediction and control of groundwater contaminant transport in an unsaturated zone.

Economic analyses of regional irrigated agricultural production typically make little distinction between perennial and annual crops despite the distinctive characteristics of perennials. Such factors include high planting costs, lags in production, long lifespan, and potentially long-lasting impacts of input use and weather shocks. This study establishes a fully dynamic model of irrigated perennial crop production in a regional context where annuals are also grown. Perennial crop area is modeled as a vintage capital stock with age-dependent yields. The model is applied to the Riverland region of South Australia to examine the possible effects of both temporary and permanent changes in water supplies and the establishment of water prices, which is then used to estimate agricultural water demand. The model demonstrates that annuals are fallowed during drought so that perennial crops may be preserved and how, due to the fixed costs of re-planting perennials, annual crops are used to smooth profits while recovering from a severe shock. In all scenarios, a very slow rate of convergence to the steady state is found, highlighting the need for models that capture the transitional dynamics of agricultural land use in areas with significant perennial production.

Despite a vigorous reintroduction program between 1985 and 2010, numbat populations in Western Australia are either static or declining. This study aimed to document the population ecology of numbats at two sites that are going against this trend: Scotia Sanctuary in far western New South Wales and Yookamurra Sanctuary in the riverland of South Australia. Scotia (64 659 ha) and Yookamurra (5026 ha) are conservation reserves owned and managed by the Australian Wildlife Conservancy and where numbats were reintroduced in 1999 and 1993 respectively. Both sites have large conservation-fence-protected introduced-species-free areas where there are no cats (Felis catus) or red foxes (Vulpes vulpes). Numbats were sourced from both wild and captive populations. From small founder populations, the Scotia numbats are now estimated to number 169 (113–225) with 44 at Yookamurra. Radio-collared individuals at Scotia were active between 13 and 31°C. Females had home ranges of 28.3 ± 6.8 ha and males 96.6 ± 18.2 ha, which leads to an estimated sustainable population or carrying capacity of 413–502 at Scotia. Captive-bred animals from Perth Zoo had a high mortality rate upon reintroduction at Scotia due to predation by raptors and starvation. The habitat preferences for mallee with a shrub understorey appear to be driven by availability of termites, and other reintroduced ecosystem engineers appear to have been facilitators by creating new refuge burrows for numbats. This study shows that numbats can be successfully reintroduced into areas of their former range if protected from introduced predators, and illustrates the difficulties in monitoring such cryptic species.

The effects of soil applications of nitrogen on the quality of fresh and dried fruit from 12-year-old apricot Prunus armeniaca cultivar Moorpark trees growing on an orthic Tenosol in the Riverland region of South Australia were studied over 3 years. The experiment was set up in a randomised complete block design with 6 annual rates of nitrogen (0, 250, 500, 750, 1000 and 1250 g/tree.year) applied in the form of ammonium nitrate. Application was split into 30% at budburst, 30% six weeks after budburst and 40% after harvest. Firmness of fruit was significantly reduced as the rate of applied nitrogen increased. The flesh of individual fruits ripened more evenly when 0 or 250 g nitrogen/tree.year was applied, compared with rates in the range 500–1250 g nitrogen/tree.year. Application of nitrogen significantly increased the pH of fruit. The total soluble solids level of fruit from trees that received 0 or 250 g nitrogen/tree.year, was significantly lower than from trees that received 750 or 1250, but not 1000 g nitrogen/tree.year. Application of nitrogen did not significantly affect the concentration of sulfur dioxide in fresh fruit measured after sulfuring, but the concentration of sulfur dioxide in fruit at the completion of drying was significantly increased. The application of nitrogen did not affect the drying ratio of fruit. Nitrogen application increased the rate of darkening of dried apricots in storage in each of the three years. Relationships were found between time taken for dried apricots to darken to an unacceptable level and nitrogen concentration in harvested fruit. It is suggested that to assist in the management of darkening of dried apricots in storage, annual nitrogen application rates on an orthic Tenosol need to be below 500 g/tree.year and ideally below 250 g/tree.year.

SUMMARYBioregionalism claims that interaction between the biophysical and human components of a region generates place-based environmental and social understanding and concern, which lead to locally shared power and responsibility in cooperative land management and governance. The Man and the Biosphere Programme's Seville Strategy calls for local community participation in a multi-stakeholder ecosystem-based approach to conservation, but it is unclear if tenets of bioregionalism play a role in its implementation. Bookmark Biosphere Reserve (BBR) in Australia has substantially succeeded in scientific research and monitoring, conservation, environmental education and sustainable land-use initiatives. Aspects of bioregionalism (for example recognition of the region's unique identity, local community sense of responsibility, integration of local knowledge, presence of motivated local leaders and cooperative community-based management through a network of groups) have contributed to success. Other crucial factors were funding, technical and scientific information and support from government agencies, leadership from members of state and federal government and from private philanthropic foundations, community capacity-building for sustainable land management and availability of volunteers from outside the region. Nevertheless, conflict arose in relation to governance, originating from the recognized difficulties of reconciling a diversity of allegiances, motivations, management styles and personalities, and resulted in division of BBR into two, one section being managed largely through the private sector and community volunteers, the other (renamed Riverland Biosphere Reserve) coordinated by a committee with more diverse affiliations. Bioregionalism can play a role in biosphere reserves but motivations and resources of external public and private organizations are also vital. Avoiding weaknesses of bioregional approaches requires greater attention to social aspects of environmental management. Governance structures and processes need to be inclusive, flexible and equitable in decision making and access to funds. They should support both agency and community-initiated activities and include conflict resolution mechanisms.

The ability of 11 species of annual medics (Medicago doliata, M. laciniata, M. littoralis, M. minima, M. orbicularis, M. polymorpha, M. praecox, M. rigidula, M. rigiduloides, M. tornata and M. truncatula) to nodulate and fix nitrogen with naturalised rhizobia from 28 South Australian soils was assessed. The number of rhizobia in the soils was estimated. Medic shoot dry matter production and nodulation were measured, after inoculation of medic seedlings with a soil suspension, in 2 glasshouse experiments. The number of medic rhizobia ranged from 0.4 10 2 to 1.5 10 6 per gram soil. Medicago laciniata was the only medic species tested which was not consistently nodulated by the soil rhizobia. While all the other species formed nodules, they varied widely in their ability to form an effective symbiosis. Symbiotic performance (which indicates how much growth the medic line achieved, when compared to an effective inoculation treatment) of the medic species ranged from 3% (M. rigiduloides) to 67% (M. praecox). Herald (M. littoralis) achieved a symbiotic performance of 49% and it was estimated that this would be insufficient to meet the nitrogen requirements of a Herald-based pasture during early growth. The symbiotic performance of Santiago (M. polymorpha) was low (17%) and erratic (from –6 to 72%). The ability of the rhizobia to form an effective symbiosis varied widely also between soil regions. For example, the rhizobia in Riverland soils resulted in only 31% of the shoot dry matter of those in Eyre Peninsula soils, in association with M. polymorpha. There are significant opportunities to improve the symbiotic performance of a number of the species of annual medics examined in this study. Options to improve the effectiveness of the symbiosis of medics with naturalised soil rhizobia are discussed.

The effect of soil-applied nitrogen on the growth and yield of 12-year-old apricot Prunus armeniaca cultivar Moorpark trees growing on an orthic Tenosol in the Riverland region of South Australia was studied over 3 years. The experiment was set up in a randomised complete block design with 6 annual rates of nitrogen (0, 250, 500, 750, 1000 and 1250 g/tree.year) applied in the form of ammonium nitrate. Application was split into 30% at budburst, 30% 6 weeks after budburst and 40% after harvest. Growth in trunk circumference was significantly greater at 750 and 1000 g/tree.year than at the other rates of nitrogen. In years 1 and 2, the weight of water shoot growth removed at pruning was significantly higher at nitrogen rates of 750–1250 g/tree.year than from trees that received no nitrogen. It is suggested that for Moorpark apricots growing on an orthic Tenosol, applying nitrogen at rates of 750 g/tree.year and above produces levels of water shoot growth that are undesirable for tree management. Nitrogen application resulted in darker and more vivid green leaves as measured with a Minolta Chroma Meter. Concentration of nitrogen in mid-shoot leaves was increased with increase in applied nitrogen. Fruit size was significantly increased by applied nitrogen in year 1, but fruit size was not significantly affected in years 2 and 3. Nitrogen application increased fruit set in the second and third year. Yield of fresh fruit was not significantly affected in the first year, but was in subsequent years with the maximum yield obtained at a rate of 1000 g/tree.year of nitrogen in both years. Yield of dried fruit followed similar trends to that of fresh fruit. Fruit maturation was delayed by 4 to 8 days by nitrogen application. After 3 years, applying nitrogen at 1250 g/tree.year the pH of soil in the top 15 cm was 4.7 compared with 6.7 where no nitrogen was applied.

The responses of grapevines (Vitis vinifera L.), ungrafted and grafted to Ramsey rootstock, to saline irrigation have been investigated in drip-irrigated trials at Loxton, Dareton and Merbein in the Riverland–Sunraysia region of the southern Murray–Darling Basin. Soil type and climate were similar across the sites and the characteristics of the soils were monitored in relation to salinity treatment. The treatments involved application of defined irrigation water salinities throughout the season at Merbein and Dareton, while at Loxton, a high salinity treatment was applied between flowering and veraison with low salinity being applied in the remainder of the season. Between-site comparisons of the same rootstock or same cultivar in the fifth season of irrigation show that for water of similar salinity (volume weighted electrical conductivity of 1.4–1.6 dS/m), the ion accumulation patterns were not equivalent. Leaf petiole sodium ion (Na+) and chloride ion (Cl–) concentrations in ungrafted Sultana vines at Dareton were 2-fold those at Merbein, which aligned with differences in electrical conductivity of the soil saturation paste extract. Differences between salinity of soil and ion content of leaves at the 2 sites were attributed to different irrigation management with the estimated leaching fraction at Merbein nearly double that at Dareton. The average ECe at Loxton was equivalent to that at Merbein. However, the leaf lamina Cl– in vines grafted to Ramsey rootstock at Loxton was 2-fold that at Merbein and leaf lamina Na+ was 10-fold. Cultivar differences between the 2 sites — Sultana at Merbein and Colombard at Loxton — may explain a small part of the increase in leaf Na+ and most of that in leaf Cl–. However, a far more plausible explanation is that vines at Loxton experienced transient waterlogging which increased their uptake of both Na+ and Cl–, and increased the rate of Na+ uptake relative to that of Cl–. Transient waterlogging was probably caused by a combination of soil sodicity, small excesses in irrigation, and the combination for part of the season of low electrolyte concentration and high sodium adsorption ratio in the soil solution. Under waterlogged conditions, the uptake of Na+ relative to Cl– at Loxton would have been further enhanced by the inherent differences between Loxton and Merbein in the properties of the soil solution. The soil solution at Loxton had a higher Na:Cl ratio.

Objectives. This paper describes the longitudinal component of a larger mixed methods study into the processes and outcomes of chronic condition management and self-management strategies implemented in three Aboriginal communities in South Australia. The study was designed to document the connection between the application of structured systems of care for Aboriginal people and their longer-term health status. Methods. The study concentrated on three diverse Aboriginal communities in South Australia; the Port Lincoln Aboriginal Health Service, the Riverland community, and Nunkuwarrin Yunti Aboriginal Health Service in the Adelaide metropolitan area. Repeated-measure clinical data were collected for individual participants using a range of clinical indicators for diabetes (type 1 and 2) and related chronic conditions. Clinical data were analysed using random effects modelling techniques with changes in key clinical indicators being modelled at both the individual and group levels. Results. Where care planning has been in place longer than in other sites overall improvements were noted in BMI, cholesterol (high density and low density lipids) and HbA1c. These results indicate that for Aboriginal patients with complex chronic conditions, participation in and adherence to structured care planning and self-management strategies can contribute to improved overall health status and health outcomes. Conclusions. The outcomes reported here represent an initial and important step in quantifying the health benefits that can accrue for Aboriginal people living with complex chronic conditions such as diabetes, heart disease and respiratory disease. The study highlights the benefits of developing long-term working relationships with Aboriginal communities as a basis for conducting effective collaborative health research programs. What is known about the topic? Chronic condition management and self-management programs have been available to Aboriginal people in a range of forms for some time. We know that some groups of patients are keen to engage with care planning and self-management protocols and we have anecdotal evidence of this engagement leading to improved quality of life and health outcomes for Aboriginal people. What does this paper add? This paper provides early evidence of sustained improvement over time for a cohort of Aboriginal people who are learning to deal with a range of chronic illnesses through accessing structured systems of support and care. What are the implications for practitioners? This longitudinal evidence of improved outcomes for Aboriginal people is encouraging and should lead on to more definitive studies of outcomes accruing for people engaged in structured systems of care. Not only does this finding have implications for the overall management of chronic illness in Aboriginal communities, but it points the way to how health services might best invest their resources and efforts to improve the health status of people with chronic conditions and, in the process, close the gap between the life expectancy of Aboriginal people and that of other community groups in Australia.

Quantified medium- and long-term hydrological datasets are scarce in South Africa, yet they are essential to gain understanding of natural systems, contribute to ecosystem conservation, and ultimately quantify water balance processes accurately. A hydrological experiment was carried out at Riverlands Nature Reserve (Western Cape, South Africa) in order to quantify the components of the soil water balance at experimental sites occupied by endemic and invasive vegetation. In two separate follow-up projects, five-year time series were collected in three treatments, namely, endemic fynbos vegetation, bare soil, and land invaded by Acacia saligna. Rainfall was recorded daily with a manual rain gauge. Groundwater levels were logged hourly at 14 boreholes. Volumetric soil water contents and soil temperatures were logged hourly at different depths in the soil profile. Groundwater levels and soil water contents responded to rainfall with very clear seasonal trends. The data can be applied in water balance and evapotranspiration studies, unsaturated flux studies, soil temperature profile studies, and rainfall-groundwater level response analysis and for calibrating and validating a wide range of hydrological models.

AbstractThe present investigation emphasized the understanding of the mechanical behavior and progressive failure modes of Kevlar/epoxy-reinforced laminated composites subjected to a three-point bend test at liquid nitrogen (LN2) temperature (77 K). The tests were conducted on the woven fabric laminates with different loading speeds and characterized by scanning electron microscopy (SEM). The effect of LN2 temperature on the interlaminar shear strength (ILSS) of Kevlar/epoxy composites with various loading speeds was observed. The results indicate that the values of ILSS were increased at higher crosshead speeds compared to ambient temperature. The fibrillation progression and matrix failure (riverline marking) was observed by SEM. A change in crosshead speed may result in the variation of failure modes.

The increasing prevalence of the grapevine trunk diseases Eutypa and Botryopshaeria dieback has been attributed, in part, to abiotic stresses imposed on vineyards as production intensifies worldwide. The aim of this study was to evaluate the influence of water deficit irrigation practices on the infection of pruning wounds by Eutypa lata and Diplodia seriata, and the subsequent rate of colonisation. Two vineyard trials were conducted over 2 years in South Australia, one in the Riverland using ‘Cabernet Sauvignon’ with four irrigation treatments (100, 50, 25 and 12.5% of the standard irrigation program) and another in the Barossa Valley using ‘Shiraz’ on six rootstocks and own roots, either irrigated or not irrigated. According to leaf water potential assessments, vines with reduced irrigation were generally in water deficit, and therefore subjected to stress. On the whole, incidence of wound infection and distance of colonisation were similar among irrigation treatments for both pathogens, except in the Riverland, where E. lata colonized canes to a greater extent in well-watered vines than those in water deficit. Only vines on rootstock ‘Ramsey’ in the Barossa Valley had greater extent of colonisation by E. lata in the non-irrigated vines. There was no correlation between internal staining and colonisation, with both pathogens recovered up to nearly 20 cm ahead of the staining. Water deficit did not increase the susceptibility of grapevine pruning wounds to infection, nor colonisation of the subtending tissue by E. lata and D. seriata. In fact, there was evidence of decreased susceptibility to colonisation by E. lata in vines subjected to severe water deficit.

Introduction Ross River virus (RRV) disease is Australia’s most common arthropod-borne disease which has an important impact on population health and productivity. The aim of this study was to identify the spatial and temporal distribution of RRV notifications during 2000–2013 in South Australia (SA). Methods The epidemiologic patterns of RRV notifications in SA from January 2000 to December 2013 were examined at a statistical local area (SLA) level. Spatial-temporal analyses were conducted using patient-reported place of exposure to characterise the recurrence of RRV infection stratified by age and sex. Results During the study period, a total of 3,687 RRV disease notifications were recorded in the state with state-wide mean annual rates of 16.8 cases per 100,000 persons and a 1:1.32 male:female ratio. The SLAs reporting cases of RRV disease exhibited spatial and temporal variation. Notified cases of RRV disease occurred more frequently in summer and autumn. A geographic expansion was observed of the area within which RRV cases occur. The comparison of age- and sex-standardised incidence rates, calculated by place of residence and patient-reported place of exposure, highlights the importance of using the latter to accurately display geospatial disease trends over time. Areas with the largest proportion of visitor cases and having the highest risk were mostly along the River Murray, which provides many vector mosquito habitats. Conclusion Although public health interventions should be considered in all SLAs where RRV occurs, we suggest that priority should be given to the Riverland areas identified as highest risk.

Purpose Australian agriculture is facing increasingly uncertain weather patterns which is impacting financial performance, exacerbated by worsening terms of trade and a decline in commodity prices. Increasing the resilience and adaptive capacity of the primary production sector is of key importance. Governments and farmer groups often depict technology adoption as the salvation of farming, frequently ignoring the importance of decision-making processes and soft information skills and needs. The purpose of this study is to explore farmer decision-making and resilience and, in doing so, address ongoing challenges with soft information, including the inaccessibility of accounting data and a lack of awareness of its formal role in strategic decisions. Design/methodology/approach Drawing on a strategic choice perspective, we explore the links between farmer characteristics, attitudes, technology orientation, decision-making and financial performance to investigate how accounting data and tools could better support growers’ adaptive capacity. Detailed on-farm interviews were conducted with 25 grape growers across the Riverland in South Australia, with information thematically and descriptively analysed. Findings Results show that farmers with low operating profit margins spend double the time making decisions and struggle with minimising variable costs, especially water costs. Lower profit growers were also less likely to perceive climate change as a threat and demonstrated lower resilience. Originality/value The results highlight the potential for accountants to make more use of data-driven technological advances and for this information to be used to enhance on-farm strategic decision-making and support innovative business models. Simply packaged biophysical and financial data could also support strategic decisions and adaptation of farmers struggling to make a profit.

Abstract. Kinyariro MS, Njuguna SG, Macharia G. 2019. Challenges and opportunities of participatory management of Upland Wetland in kiambu county, Kenya. Bonorowo Wetlands 10: 52-65. Wetlands are continuously degraded through agricultural activities, pollution, and settlements. For example, in the Lari sub-district, increased population pressure decreased soil fertility, unreliable rainfall, and the search for food security forced farmers to encroach on the seemingly idle Upland Wetlands. Opportunities for wetland conservation lie in participatory approaches that can be applied at the local level to assist in conserving this vital natural resource. The main water of the Ruiru river comes from the Upland Wetlands harvested by the Nairobi Water and Waste Company in the Githunguri sub-district at the Ruiru dam. This research is critical because the water company does not have in-depth information about its catchment area, which leads to encroachment and ultimately rationing of water in the city of Nairobi. This study aims to document the causes of wetland degradation in the highlands, assess the level of community participation, and determine the level of awareness of the importance of wetlands and the possible contribution of farmer involvement in catchment management. The sampling method used to select the research unit was stratified and random sampling where farmers and Ruiru dam workers were given a questionnaire. Purposive sampling was used to determine the WARMA manager, WRUA officer, and six older people who were interviewed. 40 farmers from the Lari 107 settlement scheme where the wetlands are located and four workers of the Ruiru dam were given questionnaires. Data analysis was performed using the Chi-square package computer, T-test, and SPSS. Percentages for qualitative data are presented using tables, bar charts, and pie charts. The wetland mapping was carried out using GIS and Google Earth. The study results found that the total land cover of upland rice fields was 129.6 Ha after deducting 105.4. Ha for the last thirty years due to encroachment. The study revealed that 65% of respondents had lived in the area for more than 20 years. Farmers drain wetlands primarily for food supply (50%), generate income (25%), while 10% do so to control waterborne diseases. Participation rates are negligible, with only 2.5% of respondents ever participating in wetland conservation. Community-based conservation groups like WRUA still lack in this area. Environmental impacts include loss of biodiversity, destruction of ornithological habitat, and loss of hydro plant species. Social effects include outbreaks of waterborne diseases such as typhoid, water pollution, and weak community conservation infrastructure. However, there is a chance for community involvement, where the majority of the population is ready to carry out conservation (X2 = 0.127, p = 0.001). The formation of community-based conservation groups such as the Water Resources Users Association, the Association of Riverland Owners, and the Watershed Advisory Committee was proposed as the primary solution. Devolution of water resources is also proposed to ensure local people benefit from selling water to city residents. Such efforts would provide an adequate supply of water to Nairobi and the surrounding satellite cities.

The singing and dancing of Darug peoples once echoed throughout the Hawkesbury Nepean riverlands in ceremony. A long and challenging walk through bushland along the Nepean River, from Emu Green to Yarramundi on the Hawkesbury River, invites the walker to meditate on the presences and absences of these river places. Yarramundi is an important site for Darug people today, as it holds the history and cultural memories of singing the rivers in song and ceremony. Walking contemporary Indigenous songlines asks how we can come to know the river through walking the contemporary songlines of Darug songwriters and artists that sing the country of the riverlands today, and what is produced when this is enacted as public pedagogy. The paper explores a process of walking the Nepean River Trail, from my home at Emu Green to the Shaws Creek and Yellomundee Aboriginal cultural trails. The walk is reproduced as public pedagogy with collaborators Leanne and Jacinta Tobin, who have deep family connections to Yarramundi: connections that were temporarily lost through their early lives, and recreated through art, language and music practices in contemporary creations of ancestral songlines and connections. The public pedagogy performance was enacted at the Circular Quay International Passenger Terminal in a presentation of three songs, 73 artworks, and a short explanatory talk to an audience of 700members of the Australian Institute of Landscape Architects. This paper asks: What does this public pedagogy produce? What does it mean to enact it at this historic site of colonial invasion and contemporary arrival of both temporary and permanent immigrants to this landscape?
