A diverse set of obstructions, occurring within different spatial, temporal and actor hierarchies, are experienced by practitioners and render the realisation of maximised biodiversity, a rarity. This research aims to illuminate why this is so, and what needs to be changed to rectify the situation. To determine meaningful findings and conclusions, capable of assisting applied contexts and accommodating a diverse range of influences, a ‘systems approach’ was adopted. This approach led to the use of a multi-strategy research methodology, to identify the key obstructions and solutions to protecting and enhancing biodiversity - incorporating the following methods: action research, a questionnaire to local government ecologists, interviews and personal communications with leading players, and literature reviews. Nevertheless, ‘case studies’ are the predominant research method, the focus being a ‘nested’ case study looking at strategic issues of the largest regeneration area in Europe ‘the Thames Gateway’, and the largest individual mixed- use mega-development in the UK (at the time of planning consent) ‘Eastern Quarry 2’ - set within the Gateway. A further key case study, focussing on the Central Riverside development in Sheffield, identifies the merits of competition and partnership. The nested cases, theories and findings show that the strategic scale - generally relating to governance and prioritisation - impacts heavily upon individual development sites. It also enables the identification of various processes, mechanisms and issues at play on the individual development sites, which primarily relate to project management, planning processes, skills and transdisciplinary working, innovative urban biodiversity design capabilities, incentives, organisational cultures, and socio-ecological resilience. From these findings a way forward is mapped, spanning aspects from strategic governance to detailed project management. KEYWORDS : Urban nature, mega-development, socio-ecological resilience, governance, project management. 2 DEDICATED TO: My dear parents, for facilitating my early appreciation of nature, and always being at the end of a telephone; and Harshada Deshpande and Debabardhan Upadhyaya, for being the most supportive and kindest friends anyone could ever wish for. 3 ACKNOWLEDGEMENTS This research was undertaken as part of a CASE (Collaborative Awards in Science and Engineering) studentship.

  • Birds & Natural History 2009-2010
    Birds & Natural History 2009-2010 Read newsworthy and lively commentary on our new blog at press.princeton.edu/blog press.princeton.edu Contents 8 Princeton Illustrated Checklists 23 Birds of Africa 10 Princeton Field Guides 23 Species Studies 16 Field Guides 24 Insects 17 Identification Guides 25 Of Related Interest 18 Photographic Guides 29 Order Form/Index 20 Reference 22 Princeton Pocket Guides A message from the Editor It’s with great pleasure that we roll out a new Birds and Natural History catalog. We’ve added a significant number of new titles to the list and 2009 promises to be a bumper year. It’s wonderful to have two classic references available in paperback for the first time ever—Macdonald’s Princeton Encyclopedia of Mammals and Perrins’ Princeton Encyclopedia of Birds. These are outstanding books that belong on every naturalist’s shelf. A new Lars Jonsson book is always cause for celebration, and in Lars Jonsson’s Birds we have a mouthwatering collection of much of the master’s recent work, once again confirming him as the doyen of wildlife artists. Jeremy Mynott’s Birdscapes is an intriguing and elegant study of man’s enduring interrelationship with birds, at once insightful, amusing, and informative. We have also just published three new titles in our Princeton Field Guides series, and particular attention should be given to Mark Brazil’s magnificent Birds of East Asia, which covers Japan, Taiwan, Korea, and the eastern Asian seaboard, an area lacking a unifying guide until now, and to Dennis Paulson’s Dragonflies and Damselflies of the West, a richly illustrated, authoritative photographic guide, soon to be followed by a volume on the East.

    LAFARGE AGGREGATES LIMITED AND LAFARGE CEMENT UK LIMITED OVERVIEW SUBMISSION IN RESPONSE TO THE COMPETITION COMMISSION’S STATEMENT OF ISSUES NON-CONFIDENTIAL VERSION April, 2012 K&E 91146101.1 OVERVIEW SUBMISSION IN RESPONSE TO THE COMPETITION COMMISSION’S STATEMENT OF ISSUES 1. This Submission is made by Lafarge Aggregates Limited and Lafarge Cement UK Limited (together, “Lafarge”) in response to the Competition Commission’s (“CC”) Statement of Issues dated 8 March 2012. A. Executive Summary 2. The timing of the CC market investigation into the supply or acquisition of aggregates, cement and ready-mix concrete (“RMX”) (the “MIR”) presents a series of challenges for both the CC and market participants, including Lafarge: Market Decline. The MIR takes place against the backdrop of an economic downturn since 2008 which has been longer and more severe than any experienced by the construction materials industry within the last 30 years. The reduction in volumes has accelerated again in 2012 with year-on-year declines for the first quarter in excess of 10 per cent for aggregates and RMX, while GB cement volumes appear likely to decline or to remain flat at best in 2012. Industry forecasts do not predict any change in these trends before at least 2014, at which point demand is expected still to remain below levels seen in 2009. Any potential improvements will develop from a low base, resulting in sustained and significant levels of overcapacity. Combination of Lafarge and Tarmac. Lafarge announced in February 2011 the proposed combination of its UK construction materials business with that of Tarmac Limited (the “Proposed JV”).

    Morgan Richards (forthcoming 2013) ‘Greening Wildlife Documentary’, in Libby Lester and Brett Hutchins (eds) Environmental Conflict and the Media, New York: Peter Lang. GREENING WILDLIFE DOCUMENTARY Morgan Richards The loss of wilderness is a truth so sad, so overwhelming that, to reflect reality, it would need to be the subject of every wildlife film. That, of course, would be neither entertaining nor ultimately dramatic. So it seems that as filmmakers we are doomed either to fail our audience or fail our cause. — Stephen Mills (1997) Five years before the BBC’s Frozen Planet was first broadcast in 2011, Sir David Attenborough publically announced his belief in human-induced global warming. “My message is that the world is warming, and that it’s our fault,” he declared on the BBC’s Ten O’Clock News in May 2006. This was the first statement, both in the media and in his numerous wildlife series, in which he didn’t hedge his opinion, choosing to focus on slowly accruing scientific data rather than ruling definitively on the causes and likely environmental impacts of climate change. Frozen Planet, a seven-part landmark documentary series, produced by the BBC Natural History Unit and largely co-financed by the Discovery Channel, was heralded by many as Attenborough’s definitive take on climate change. It followed a string of big budget, multipart wildlife documentaries, known in the industry as landmarks1, which broke with convention to incorporate narratives on complex environmental issues such as habitat destruction, species extinction and atmospheric pollution. David Attenborough’s The State of the Planet (2000), a smaller three-part series, was the first wildlife documentary to deal comprehensively with environmental issues on a global scale.

We investigated how traditional care of dogs affected rural birds and other animal populations. Using camera traps, it was found that the food fed to dogs was also taken by seven species of birds and at least three species of mammals. The most numerous species taking dog food was the house sparrow, Passer domesticus, which is declining in Europe. In the case of this species, females were more likely than males to use food provided for dogs, with a clear preference for food prepared in the human kitchen. We conclude that the food provided to domestic pets can be an important component of the diet of wild birds and mammals living close to humans. Abstract: Access to food is crucial in the life of birds and affects reproduction, survival and, conse- quently, population size.
