    Critical Reflections on Building a Community of Conversation about Water Governance in Australia

    Get PDF
    Water governance has emerged as a field of research endeavour in response to failures of current and historical management approaches to adequately address persistent decline in ecological health of many river catchments and pressures on associated communities. Attention to situational framing is a key aspect of emerging approaches to water governance research, including innovations that build capacity and confidence to experiment with approaches capable of transforming situations usefully framed as ‘wicked’. Despite international investment in water governance research, a national research agenda on water governance was lacking in Australia in the late 2000s as were mechanisms to build the capacity of interdisciplinary and transdisciplinary research and collaborative policy practice. Through a two-year Water Governance Research Initiative (WGRI), we designed and facilitated the development of a community of conversation between researchers concerned with the dynamics of human-ecological systems from the natural sciences, humanities, social sciences, policy, economics, law and philosophy. The WGRI was designed as a learning system, with the intention that it would provide opportunities for conversations, learning and reflection to emerge. In this paper we outline the starting conditions and design of the WGRI, critically reflect on new narratives that arose from this initiative, and evaluate its effectiveness as a boundary organisation that contributed to knowledge co-production in water governance. Our findings point to the importance of investment in institutions that can act as integrative and facilitative governance mechanisms, to build capacity to work with and between research, policy, local stakeholders and practitioners

    A Volcano-Plutonic Association in Northeastern New South Wales

    In the Emmaville-Tenterfield region of northeastern New South Wales, Late Permian comagmatic volcanic and high-level intrusive rocks are spatially associated with large cauldron structures. Major economic concentrations of cassiterite, molybdenite and wolframite are associated with specific leucogranitoid plutons which were intruded to subvolcanic levels in regions between discrete cauldrons. Chemical, mineralogical and field data, used to relate the associated calc-alkaline volcanic and intrusi ve rocks and the various types of mineralization, have led to the recognition of a volcano-plutonic association displaying features common to volcanoplutonic associations developed in evolved geosynclinal environments in many other parts of the world. Igneous activity in the Emmaville-Tenterfield region commenced with the accumulation of large volumes of leucoadamellite and adamellite magma generated by minimum and non-minimum progressi ve partial melting of lower crustal rocks of presumed adamellitic composition. Intrusion of these magmas to high levels within Early Permian silicified siltstones and sandstones induced doming and fracturing of the brittle sedimentary rocks above specific magma chambers, leading to the upward venting of magmas along arcuate fractures and eventual eruption in the form of pyroclastic volcanism. The Emmaville Volcanics so formed, consist of a large number of individual ash flows, minor lava flows and rare ash-fall units which comprise a thick sequence of dominantly rhyolitic volcanics ranging in composition from dacite to high-silica rhyolite. Rare andesites and associated mafic rhyodacites are also present and constitute a geochemically distinct group apparently unrelated to the bulk of the Emmaville Volcanics. The evacuation of large volumes of magma from the high-level chambers caused subsidence of the overlying sedimentary and fresh volcanic rocks, forming simple cauldrons of the Glencoe type
