    This is the final version. Available on open access from IWA Publishing via the DOI in this recordOwing to climate change related uncertainties and anticipated population growth, different parts of the developing and the developed world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Alternative Water Supply Systems covers technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining. A number of case studies from the UK, the USA, Australia and the developing world are presented to discuss associated environmental and health implications. The book provides insights into a range of aspects associated with alternative water supply systems and an evidence base (through case studies) on potential water savings and trade-offs. The information organized in the book is aimed at facilitating wider uptake of context specific alternatives at a decentralized scale mainly in urban areas. This book is a key reference for postgraduate level students and researchers interested in environmental engineering, water resources management, urban planning and resource efficiency, water demand management, building service engineering and sustainable architecture. It provides practical insights for water professionals such as systems designers, operators, and decision makers responsible for planning and delivering sustainable water management in urban areas through the implementation of decentralized water recycling

The Australian trends include further warming and sea level rise sea level rise (SLR), with more hot days and heatwaves, less snow, more rainfall in the north, less April–October rainfall in the southwest and southeast and more extreme fire weather days in the south and east. The New Zealand trends include further warming and sea level rise (SLR), more hot days and heatwaves, less snow, more rainfall in the south, less rainfall in the north and more extreme fire weather in the east. There have been fewer tropical cyclones and cold days in the region. Extreme events include Australia’s hottest and driest year in 2019 with a record-breaking number of days over 39°C, New Zealand’s hottest year in 2016, three widespread marine heatwaves during 2016–2020, Category 4 Cyclone Debbie in 2017, seven major hailstorms over eastern Australia and two over New Zealand from 2014–2020, three major floods in eastern Australia and three over New Zealand during 2019–2021 and major fires in southern and eastern Australia during 2019–2020

    The development of tools and guidelines for surfing resource management

    Get PDF
    Surfing is a mainstream pastime and competitive sport in many countries and provides a full range of economic, social, physical, and mental health benefits. Maintaining the integrity of surf breaks has proven to be a challenge, with a litany of degraded or destroyed surfing locations worldwide. This is attributed to a deficiency in expertise and experience in implementing surf science and management within governing authorities, associated consultants, or stakeholder groups; combined with a lack of value recognition and identification. This work considers how surf breaks as coastal resources could be better managed. A literature review of technical reports, published articles, statutory instruments, evidence, and consents, along with interactive stakeholder workshops and surveys to identify key considerations, are combined with complex numerical modelling and machine learning methods to develop tools for effective surf break management. In Aotearoa New Zealand, a surf break is described in policy as having various geophysical components in the vicinity of locations where surfing takes place and the areas offshore. Given the wide range of benefits associated with surfing, and the complexities of managing a natural resource, albeit in some cases anthropologically modified, the term ‘surfing resource’ was established and defined as a major outcome of this work and as a step in the process of developing a set of Management Guidelines for Surfing Resources (the Guidelines). The Guidelines, which are a world first, consider what aspects of the environment are the most important to surfing resources management, provide direction, as implementable steps, to authorities and proponents of activities in the coastal environment that can impact surfing resources, and include identification and monitoring strategies as well as a novel risk assessment framework which is underpinned by a surf break’s sensitivity as a function of geomorphological composition. The Guidelines are supported by research streams that required field data collection and monitoring system development, numerical modelling, and machine learning to improve our understanding of surf break functionality and/or better our management strategies. This work emphasises the role of bathymetric features outside the surf zone that contribute to surfing wave quality, and the value of establishing swell corridors for management purposes. An automated system has been developed to monitor the key surfing wave quality indicator of peel angle through both space and time. Effective surfing resource management requires a holistic, inclusive, case-by-case approach, that may require cultural, social and geophysical assessment, which is best implemented proactively with the identification of surfing resources and the establishment of environmental baselines

    Measuring knowledge sharing processes through social network analysis within construction organisations

    Get PDF
    The construction industry is a knowledge intensive and information dependent industry. Organisations risk losing valuable knowledge, when the employees leave them. Therefore, construction organisations need to nurture opportunities to disseminate knowledge through strengthening knowledge-sharing networks. This study aimed at evaluating the formal and informal knowledge sharing methods in social networks within Australian construction organisations and identifying how knowledge sharing could be improved. Data were collected from two estimating teams in two case studies. The collected data through semi-structured interviews were analysed using UCINET, a Social Network Analysis (SNA) tool, and SNA measures. The findings revealed that one case study consisted of influencers, while the other demonstrated an optimal knowledge sharing structure in both formal and informal knowledge sharing methods. Social networks could vary based on the organisation as well as the individuals’ behaviour. Identifying networks with specific issues and taking steps to strengthen networks will enable to achieve optimum knowledge sharing processes. This research offers knowledge sharing good practices for construction organisations to optimise their knowledge sharing processes

    Talent Identification and Development in Sports Performance

    Get PDF
    The identification and development of talent have always been a relevant topic in sports performance. In fact, a significant body of research is available worldwide discussing this longitudinal process, the qualities that underpin elite sports performance, and how coaches can facilitate the developmental process of talented athletes. Despite the continued interest given to issues of talent identification and development, recent literature highlights the low predictive value of applied and theoretical talent identification models. Talent is the expression of a complex and multidimensional phenomenon, where, despite the existing practical recommendations, many coaches and stakeholders continue to fail to adequately value the distinction between growth, maturation, and training age. Technological resources have enabled important advances, however, this has been limited essentially to defining or validating motor skills variables or genetic markers that characterize the most talented athletes. Emerging technological resources and recent methodological advances are enabling integrated assessment and monitoring to include maturational, physiological, biomechanical, and perceptual skills while also creating optimal environments for performance and dealing with injury prevention and recovery
