    Resilient ecological solutions for urban regeneration

    Get PDF
    There is a need for biological conservation at the global scale, and urban conservation has the potential to support the delivery of this wider goal. Despite historic trends, efforts are underway to protect and enhance the quality, quantity and accessibility of green infrastructure within cities, including biodiversity features within new developments. However, there are questions over their long-term persistence and function. This paper applies an urban futures resilience analysis to a case study site to illustrate how such concerns may be explored and addressed in practice. The analysis identifies vulnerable sustainability solutions and clarifies the aspects that may be improved. The results suggest that the resilience of these solutions is questionable, even though resilience has clearly been considered. In particular, future compliance with, and enforcement of, planning conditions is questionable. The resilience of these ecological solutions may be improved by including some redundancy, designing for low maintenance, incorporating microclimate buffers and locating features in areas unlikely to be subject to future disturbance. The establishment of endowment funds or other dedicated funding mechanisms should also be explored. The paper also recommends that a futures-based resilience analysis be included within the development planning process

    A review of GIS-based information sharing systems

    GIS-based information sharing systems have been implemented in many of England and Wales' Crime and Disorder Reduction Partnerships (CDRPs). The information sharing role of these systems is seen as being vital to help in the review of crime, disorder and misuse of drugs; to sustain strategic objectives, to monitor interventions and initiatives; and support action plans for service delivery. This evaluation into these systems aimed to identify the lessons learned from existing systems, identify how these systems can be best used to support the business functions of CDRPs, identify common weaknesses across the systems, and produce guidelines on how these systems should be further developed. At present there are in excess of 20 major systems distributed across England and Wales. This evaluation considered a representative sample of ten systems. To date, little documented evidence has been collected by the systems that demonstrate the direct impact they are having in reducing crime and disorder, and the misuse of drugs. All point to how they are contributing to more effective partnership working, but all systems must be encouraged to record how they are contributing to improving community safety. Demonstrating this impact will help them to assure their future role in their CDRPs. By reviewing the systems wholly, several key ingredients were identified that were evident in contributing to the effectiveness of these systems. These included the need for an effective partnership business model within which the system operates, and the generation of good quality multi-agency intelligence products from the system. In helping to determine the future development of GIS-based information sharing systems, four key community safety partnership business service functions have been identified that these systems can most effectively support. These functions support the performance review requirements of CDRPs, operate a problem solving scanning and analysis role, and offer an interface with the public. By following these business service functions as a template will provide for a more effective application of these systems nationally

    The Impact of Policy Drivers on the Logistics Supply Chain.

    This report is designed to highlight the impact of policy drivers on the freight logistics supply chain. This section will define the term policy drivers and outline the different types of impacts the can have upon the logistics supply chain. In Section Two a list of policy drivers is presented, along with associated policy levers. An attempt to assess what impact each policy lever has on the logistics supply chain is made in Section Three and in Section Four a number of policies levers are selected to take forward as possible scenarios to be evaluated in the University of Leeds cost modelling work. Policy drivers are defined as broad aims, targets or statements that are considered to be desirable by the various bodies of government or non-government organisations in satisfying their overall goals such as “maximising social welfare”, “staying in power” etc... The types of policy drivers vary by organisation and may be complimentary or contradictory. They may also change over time as new doctrine is implemented or new research findings put into practise. In the Government’s, ‘Transport 2010 - The 10 Year Plan’ (DFT, 2000) the policy drivers are outlined under the heading ‘Vision’ and are presented below, · Fully integrated public transport information, booking and ticketing systems; · Safer and more secure transport accessible to all; and, · A transport system that makes less impact on the environment. Policy levers are the policy instruments used to attain policy drivers and can be used to achieve more than one Both policy drivers and policy levers can be categorised under two headings as outlined below, a) Fiscal Drivers; and, b) Physical & Regulatory Drivers The implementation of these policies leads to both direct and indirect outcomes that will make some contribution to achieving the policy drivers set out by the government. The policy levers will impact upon the freight industry in a positive, negative or neutral manner and for the purposes of the next section three definitions have been formulated which have been related to the impact of policy levers on costs and externalities. In Section Four a broader range of impacts are discussed for the policy levers that have been selected as possible scenarios. A Positive Impact - Any outcome that, 1) Lowers operating cost without increasing externalities, and/or; 2) Lowers externalities without increasing costs. A Neutral lmpact – Any outcome that, 1) Maintains defacto operating costs without changing externalities, and/or; 2) Maintains defacto externalities with out changing operating costs. A Negative Impact – Any outcome that, 5 1) Increases operating costs, and/or; 2) Increases externalities. Making a judgement as to whether any one policy is beneficial or not is difficult in the absence of any data and will differ depending upon who you are. The judgements that will be made in this paper will apply to the freight logistics industry only and the externalities they produce. It is stressed that they are not exact. The next section will outline in more detail some of the possible policy drivers that either currently apply to or could be applied to the freight logistics industry. The likely policy levers that could arise from the policy drivers are then discussed along with the possible transport outcomes and their impact

    Traffic Alert and Collision Avoidance System (TCAS): Cockpit Display of Traffic Information (CDTI) investigation. Phase 1: Feasibility study

    Get PDF
    The possibility of the Threat Alert and Collision Avoidance System (TCAS) traffic sensor and display being used for meaningful Cockpit Display of Traffic Information (CDTI) applications has resulted in the Federal Aviation Administration initiating a project to establish the technical and operational requirements to realize this potential. Phase 1 of the project is presented here. Phase 1 was organized to define specific CDTI applications for the terminal area, to determine what has already been learned about CDTI technology relevant to these applications, and to define the engineering required to supply the remaining TCAS-CDTI technology for capacity benefit realization. The CDTI applications examined have been limited to those appropriate to the final approach and departure phases of flight
