Satellite Rainfall Estimates Over South America - Possible Applicability to the Water Management of Large Watersheds1

This work analyzes high-resolution precipitation data from satellite-derived rainfall estimates over South America, especially over the Amazon Basin. The goal is to examine whether satellite-derived precipitation estimates can be used in hydrology and in the management of larger watersheds of South America. High spatial-temporal resolution precipitation estimates obtained with the CMORPH method serve this purpose while providing an additional hydrometeorological perspective on the convective regime over South America and its predictability. CMORPH rainfall estimates at 8-km spatial resolution for 2003 and 2004 were compared with available rain gauge measurements at daily, monthly, and yearly accumulation time scales. The results show the correlation between satellite-derived and gauge-measured precipitation increases with accumulation period from daily to monthly, especially during the rainy season. Time-longitude diagrams of CMORPH hourly rainfall show the genesis, strength, longevity, and phase speed of convective systems. Hourly rainfall analyses indicate that convection over the Amazon region is often more organized than previously thought, thus inferring that basin scale predictions of rainfall for hydrological and water management purposes have the potential to become more skillful. Flow estimates based on CMORPH and the rain gauge network are compared to long-term observed average flow. The results suggest this satellite-based rainfall estimation technique has considerable utility. Other statistics for monthly accumulations also suggest CMORPH can be an important source of rainfall information at smaller spatial scales where in situ observations are lacking.

Land use, water quality and ecological responses in Lake Colac – trends from Australia

Purpose - Recently, Colac Otway Shire in Australia released its management plan for Lake Colac, claiming over-enrichment of the lake with nutrients and degraded water quality. This paper aims to investigate these claims by establishing a correlation between key water and ecological indicators and land uses.

Design/methodology/approach - Examines the correlation between impairment and stressors in Lake Colac. This was achieved by identifying the likely sources of pollutants into Lake Colac; identifying any existing monitoring program; and characterizing the water and sediment inputs. The likely impacts of increased nutrients and sediment levels on indigenous flora and fauna were also examined. The use of meiofauna (very small benthic metazoan animals) was investigated as an indicator of degraded sites. Plankton diversity as a measure of water health was also assessed.

Findings - Water quality in Lake Colac was found to vary both temporally and spatially, and exhibited low attainment against acceptable trigger values/objectives. At current levels the lake can be classified as poorly degraded. Likely sources of pollution were identified to be related to land uses in the catchments. The biota of the lake, investigated at four study sites, yielded a sparse, benthic macrofaunal assemblage that was dominated by oligochaetes. In contrast, an abundant and taxonomically diverse meiofaunal assemblage was noted. Future meiofaunal analyses are likely to resolve suitable biotic indicator species of free-living nematodes in response to land use and waterway threats specified in the study. Originality value - This work will provide a better understanding of integrated environmental systems to enable development of best management practices, thus transforming the way the land and water are used in the future. Following the present work, other key water and ecological indicators (increased dispersion and dominance of biological species) at five additional sites were studied. Alternative management options for the effluent generated at Colac Sewage Treatment Plant and possible ecological effects of each option were also evaluated. More recently, a sediment characterization study was also carried out at sensitive sites representative of locations where build up of sediments and algae outbreaks are reported. This will enable classification of sediment and evaluation of dredging options.

Deconstructing diversity discourses in the fields of educationnal management and leadership

Discourses of diversity have supplanted those of equal opportunity or social justice in many Western democratic societies. While the notion of diversity is seemingly empowering through its recognition of cultural, religious, racial and gender difference within nation states, the emergence of this discourse during the 1990s has been in the context of neoliberal managerialist discourses that assume social action is fully explicable through theories of maximizing self interest. Thus notions of diversity, while originating in collective demands of social movements of feminism, anti racism and multiculturalism of the 1970s and 1980s, have in recent times privileged learning and leadership as an individual accomplishment and not a collective practice. Thus the dominant discourse of diversity is more in alignment with the deregulatory aspects of the increasingly managerial and market orientation of schooling, decentring earlier discourses of more transformatory notions premised upon reducing inequality and discrimination and developing ‘inclusivity’ in and through schooling. This paper provides a contextual and conceptual framework through which to explore the intersections and divergences of discourses of diversity in schools and their practical application.

Managing sport in drought-new stakeholders and new governance issues : a case study

Globally, almost every nation is facing some form of water crisis (World Commission on Water 2000). In Australia, the sport and recreation industry is one of the highest consumers of water. Other high water consuming industries (such as agriculture and farming) have been forced to adhere to strict managerial and governance reform due to the water crisis, yet in the sport and recreation industry, such changes are yet to be implemented and fully realised across the sector.

This research examines the impacts of drought and sustainable water management for sport and recreation. Specifically, it provides a case study of sport and recreation provision in a municipality that has already undergone considerable reform due to long-term drought. Sport and recreation use water for purposes such as irrigation of playing fields/pitches, filling swimming pools, stadium amenities and facilities, kitchens, maintenance and cleaning, and clubhouse amenities.

For sports that are heavy users of water for the maintenance of playing fields (such as soccer, Australian Rules football, rugby league, rugby union, grass and clay tennis courts to name a few) the impacts of drought and water restrictions have been severe. Some sports have reported an increase in the risk of injury to participants because of the condition of un-watered playing fields (Sport and Recreation Victoria 2007). Others have been forced to delay or shorten their seasons (Sleeman 2007), or worse still, cancel training and organised competition completely (Connolly and Bell 2007). While the impact of water restrictions has been profound on most sports, there are some sports that are not heavy water users and the impact of drought and water restrictions has been minimal. This problem creates issues and apparent inequities raising the need to further examine water consumption in sport and recreation. The potential outcome that arises is that the future of those sports that cannot conduct their competitions may be disadvantaged, while other sports that do not have such problems may be able to flourish.

Water, and those who control the supply of it, then defines which sports are able to flourish and sustain sport development pathways, compared to those whose survival may be in jeopardy. This research explores the stakeholder management and governance issues that have resulted for sport and recreation in the City of Greater Geelong (CoGG) located in Victoria, Australia--a region in long-term water crisis. The supply of sport and recreation facilities in the CoGG (like most municipalities in Australia) is largely the responsibility of the municipal council. The corporation responsible for the supply of water to the municipality is Barwon Water.

Although other sport and recreation facilities exist in the CoGG, the municipal council of CoGG owns and maintains over 120 sporting ovals (including the stadium used by its professional Australian Football League (AFL) team, the Cats), six swimming pools, and three golf courses. The CoGG host their professional AFL team, a range of local, national and international sport events, and provide a wide range of sport and recreation facilities for the community residents.

Eight interviews were conducted in total. Interviews were conducted with representatives from CoGG municipal council (who are responsible for the delivery of sport and recreation services and facilities in Geelong), and representatives from Barwon Water (who are responsible for the ongoing provision and maintenance of sport and recreation services and facilities) through the provision of water. Results show that the ten highest users of water in the municipality are sport and recreation facilitieswhich between them use almost one-third of the city's total water consumption (City of Greater Geelong 2006).

The municipal council is under considerable pressure to find ways to continue to provide sport and recreation opportunities for community members, as well as professional athletes and teams who use these facilities despite water restrictions. After all, these facilities provide benefit to spectators and participants, as well as businesses that rely on visitors to Geelong for sport and recreation events.

Due to such pressures, from 2007, the CoGG and Barwon Water agreed to provide the sport and recreation sector with water allocations rather than to be denied of all water under the water restriction regimes in place in the municipality. During 2007 summer sport season, this allowed the CoGG to keep 16 of its 120 sporting ovals open for participation through allocating all available water to these fields in order to keep them safe and playable. However, CoGG and Barwon Water were required to devise a rating scale to determine which sports (and sport facilities) were to share the allocated water, and which were not. These decisions also had knock on effects through sports. In order to ensure the safety of the playing surfaces, the CoGG and Barwon Water also restricted use of fields to competition only, therefore sport participants were forced to train on local beaches and other parkland areas-transferring issues of safety and public liability to other locations and facilities in the community. Further, it was reported that scheduling of competition seasons and individual matches; as well as the allocation of "home ground" gate receipts and concessions profits were required to be governed by the CoGG and Barwon Water as the competing sports were unable to agree. Perhaps more importantly, the rating scale developed for water allocation also resulted in some sports being rated as ineligible for water and as a result were unable to stage their entire competitions.

Clearly, the water allocation rating scale, and approach taken in this municipality to the continued delivery of sport and recreation has provided a workable solution. However, this study also signals that new stakeholders have entered the arena for the governance of sport. Governance structures in sport and recreation are being impacted as a result of the water crisis.

Those making decisions about which sport and recreation activities and/or facilities will be assisted with water resources are being made by local councils and water corporations. Sport managers are being required to understand existing areas of knowledge (such as turf management) in different ways, to gain knowledge in new areas (such as sustainable water management), and to lobby new stakeholder groups (such as water corporations) in order to secure their futures. The continued existence of some sports is no longer in the hands of governing bodies, but in the hands of local councils, and water corporations.

Clearly, any of the solutions implemented as discussed above, require multiple stakeholders to interact, and to reach agreement in order to assist in sustainable management of water in sport and recreation. In this sense, the management of water in sport (and all other industries) is more than a rational decision about policy, legislation, restrictions and resource allocations. It is a social and political process requiring scholarly attention for practical solutions.

Appraisal of random and systematic land cover transitions for regional water balance and revegetation strategies

This study describes the use of landscape transition analysis as a means for effective basin management. Land cover transitions from 1995 to 2002 were analyzed using a cross-tabulation matrix for an important economic zone in south-west Victoria, Australia. Specifically, the matrix was used to determine whether the transitions were random or systematic. Random landscape transitions occur when a land cover replaces other land covers in proportion to their availability. Systematic landscape transitions occur when there are deviations from random patterns, and land use types ‘target’ other land use types for replacement. The analysis was conducted with 11 land cover categories and showed that dryland pastures have been systematically losing area to dryland crops and blue gum (Eucalyptus globulus) plantations. Dryland crops have systematically expanded in the north-east of the catchment, an area where increasing in-stream salinization has occurred concurrently with this transition. The systematic expansion of the blue gum plantations has been predominantly in the south-west of the catchment and has the potential to reduce stream flows and groundwater recharge in an already water-stressed region, as blue gums use more water than the dryland pastures they are replacing. All other transitions were largely random. These findings have implications for land use planning in the study area for regional water balance and revegetation strategies. Landscape transition analysis is a cost-effective means of contributing to the management of water resources at a regional scale, and is highly recommended for future basin planning.

Clinical risk management and the ethics of open disclosure : part 1 : benefits and risks to patient safety

Patient safety experts and other authorities have strongly postulated the open disclosure of errors and adverse events to patients as an essential component of effective clinical risk management in health care. Commentators also contend that ‘when things go wrong’, openly disclosing such events to the patient and his or her nominated support person is simply ‘the right thing to do’. Despite the obvious importance of the issue of open disclosure and its possible implications for the nursing profession, it has not been comprehensively addressed in the nursing literature. A key aim of this article (the first of a two-part discussion) is to contribute to the positive project of redressing this oversight by providing a brief overview of what open disclosure is and what its intended purpose, aims, and rationale are. Consideration is also given to the risks and benefits of open disclosure as a public policy and whether it will succeed in achieving the anticipated outcomes envisaged. In a second article (to be presented as Part II), the ethics of open disclosure and its possible implications for the nursing profession are explored.

The politics of NGOs : empowering marginal groups in a climate of micro-management and distrust

The role of peak NGOs in Australian civil society is considered crucial for representing marginal groups in the public and policy arena. The Howard government had particularly challenged the advocacy, coordination, information, research and policy role of peak NGOs. Instead of dealing with NGOs, the Howard government developed a 'governing through communities' process establishing new arrangements between the Federal government and local communities. It is of concern that 'governance through communities' may directly erode the values of voluntary association, broad representation of diverse groups in society and may negate non-instrumental political relations that NGOs aim to contribute to a healthy democracy. How the new Rudd government relates to peak NGOs is thus worthy of close analysis to understand what democratic role especially peak NGO's will play in Australian civil society.

Place-based knowledge networks : the case of water management in South-West Victoria, Australia

This article aims to investigate the need for effective exchanges between knowledge generators and knowledge users in water management. Firstly, we explore the use of adaptive management for water governance and then outline the communication issues of water-management knowledge at a regional scale. Central to this approach is the need to harness 'local' knowledge that can be used to develop community participation in local water governance. Accordingly, we propose a three-network communication model to illustrate the process and identify the issues of concern for developing place-based strategies. Since research plays a central role in knowledge generation, one of the first ways to proceed is to recognise local research and incorporate it into an inclusive decision-making process. One way to achieve this is through the development of regional networks that are openly available to all, and we explore this by focusing on the place of 'network thinking' at local scale using a newly developed regional network for local knowledge dissemination in south-west Victoria, Australia. We conclude that so far this new network is too heavily reliant upon one web-based tool and outline a broader range of strategies that can be used to achieve its aims.

Water, weeds and autumn leaves : learning to be drier in the alpine region

Our paper explores how and what adults living and working in the Alpine region of Victoria understand and are learning about the changes to water availability, in a time when the response to water availability is subject to extensive debate and policy attention. Interviews for this study were conducted in the towns of Bright and Mount Beauty, with participants drawn from across the Alpine region. The interviews focused on what local stakeholders from the Alpine region understood about water availability in the region and how and what they had learned about living and working with climatic changes in their local area.

The findings of our study see that there was evidence of a strong understanding of the direct and indirect impact of climate change on participants' local community area. The study also sees evidence of learning through a community 'frames of reference' as outlined by Berkhout, Hertin and Dann et al.

Principalship and policy in small New Zealand primary schools

This research investigates the relationship between principalship and policy in small New Zealand primary schools. A distinctive feature of small primary schools is that their principals typically have to teach as well as manage. Overseas research indicates that in times of educational reform, teaching principals face particular difficulty and may need special support. Following the watershed educational reforms of 1989 and a decade of ‘hands-off’ policy in education (1989-1999), central policy towards school support in New Zealand is now more ‘hands-on’. The impact of this policy change on small schools has not been researched hi New Zealand, where such schools make up over fifty percent of all primary schools. The aims of this study are to analyse the impact of current support policy in New Zealand on small primary school principalship, and to evaluate the extent to which policy adjustment might be needed in the future. Using multiple methods and a case study approach to gather data, the study focuses on small school principalship in one New Zealand region - the Central Districts region. It also considers the recent policy initiatives, their rationale and the extent to which they appear to be meeting the support needs reported by the principals whose work has been researched in the study. Broadly, the study has found that within small schools, the role-balance within a teaching principal’s work is a critical factor, as the ratio within the principal’s role-balance between the teaching role and the management role creates variation in work-demands, work-strategies and types of support needed. Teaching principals in New Zealand generally feel better supported now than they did in the 1990s and the study identifies factors associated with this change. However the analysis in this study suggests that the current policy aim to both rationalise and strengthen the small school network as a whole is rather problematic. Without better targeted support policy in this area, old style parochial and competitive attitudes between schools are unlikely to change in the future.

Determinants of Central bank independence and governance : problems and policy implications

Central bank independence and governance (CBIG) is a term subject to conflicting definitions and so its related studies are difficult to compare. This paper therefore focuses on developing of a more useable definition, and an index model identifying the determinants of independence and governance and their possible policy implications. It also examines various independence measurement tools such as ranking and index. The index model resulting centres on key central bank independence and corporate governance issues, such as, legal aspects, political aspects, price stability objective aspects, exchange rate policy aspects, monetary policy and deficit financing aspects and finally, transparency and accountability aspects.

Integrated system for high quality water recovery and wastewater treatment

This thesis unveils an integrated system that once applied, could standardise and simplify the processes used for high quality water recovery and wastewater treatment. It forsees lower prices of desalinated and recovered water, in a streamlined and more efficient water industry, by departing from today's thinking of conventional wastewater treatment.

Water regime and salinity changes in wetland macroinvertebrate communities

The research successfully showed how biological communities change in wetlands that are affected by salinity and altered water regimes as a result of irrigation and river regulation. As an outcome of the study, recommendations have been made for the future management of wetlands in the Kerang region in northern Victoria.

‘Inspired and assisted’, or ‘berated and destroyed’? Research leadership, management and performativity in troubled times

Research leadership in Australian universities takes place against a backdrop of policy reforms concerned with measurement and comparison of institutional research performance. In particular, the Excellence in Research in Australian initiative undertaken by the Australian Research Council sets out to evaluate research quality in Australian universities, using a combination of expert review process, and assessment of performance against ‘quality indicators’. Benchmarking exercises of this sort continue to shape institutional policy and practice, with inevitable effects on the ways in which research leadership, mentoring and practice are played out within university faculties and departments. In an exploratory study that interviewed 32 Australian academics in universities in four Australian states, we asked participants, occupying formal or informal research leadership roles, to comment on their perceptions of research leadership as envisioned and enacted in their particular workplaces. We found a pervasive concern amongst participants that coalesced around binaries characterized in metaphoric terms of ‘carrots and whips’. Research leadership was seen by many as managerial in nature, and as such, largely tethered to instrumentalist notions of productivity and performativity, while research cultures were seen as languishing under the demoralizing weight of reward and punishment systems. Here, we consider what is at stake for the future of the academic workforce under such conditions, arguing that new models of visionary research leadership are urgently needed in the ‘troubled times’ of techno-bureaucratic university reforms.

Stakeholder involvement and interplay in coastal zone management and marine protected area planning

Most of Australia’s coastline and marine waters are crown ‘land’ and can be accessed by the public. As a result, many different users and stakeholder groups have an interest in coastal and marine planning and management decisions. As a way of analysing stakeholder involvement and interplay in coastal zone management and marine protected area (MPA) development in Australia, three case studies are presented to dissect the issues and explore common themes. The three themes are 1) Stakeholder involvement in implementing the oceans policy, 2) Stakeholder involvement in marine protected area network identification and 3) Stakeholder involvement in coastal land issues.
