Cost-Benefit Analysis in a Framework of Stakeholder Involvement and Integrated Coastal Zone Modeling

Active involvement of local stakeholders is currently an increasingly important requirement in European environmental regulations such as the EU Water Framework Directive (WFD) and the EU Marine Strategy Framework Directive (MSFD). The same is true for economic analyses such as cost-benefit analysis (CBA). For example, the Swedish WFD implementation requires i) quantification of cost and benefits of proposed measures and ii) stakeholder involvement. How can these two requirements be integrated in practice? And can such requirements facilitate implementation of projects with a potential net benefit? This paper presents a stepwise CBA procedure with participatory elements and applies it for evaluating nutrient management options for reducing eutrophication effects in the coastal area of Himmerfjärden SW of Stockholm, Sweden. The CBA indicates a positive net benefit for a combination of options involving increased nitrogen removal at a major sewage treatment plant, creation of new wetlands and connecting a proportion of private sewers to sewage treatment plants. The procedure also illustrates how the interdisciplinary development of a coupled ecological-economic simulation model can be used as a tool for facilitating the involvement of stakeholders in a CBA.cost-benefit analysis; stakeholder involvement; integrated modeling; eutrophication

Climate Change and Cultural Heritage: developing a landscape-scale vulnerability framework to measure and manage the impact of climate change on coastal historic landscapes

The impacts of climate change, including sea-level rise, coastal erosion, and flooding, have the potential to damage or destroy archaeology and cultural heritage assets. Most studies that have modelled or measured the impact of coastal and climatic processes on archaeology have focussed on archaeological features as discrete entities rather than as part of the historic landscape. The results, therefore, can only inform a comparison between single sites and do not reveal threats to the wider cultural heritage and historic landscape. This thesis develops a Landscape Vulnerability Framework, which uses several methodologies to establish the vulnerability of the historic landscape to climate change and identify sustainable management approaches. Each step of the framework is tested on the Dysynni valley and estuary (west Wales), which acts as a pilot study for the methods being developed. Historic Landscape Characterisation characterises the historic landscape into definable areas with similar form, function and history. This is based on an analysis of aerial photographs, modern and historic maps, archaeological database records, archive research, and geophysical surveys. A two-step vulnerability index is then developed to determine the vulnerability of the historic landscape to climate change. The first step assesses the vulnerability of archaeological sites and landscape features to climate change. The second step uses the results of the first vulnerability index, as well as spatial data on the landscape character areas and the threat in question, to calculate the vulnerability of each landscape character area to climate change. The results of the vulnerability index are used to inform a sustainability assessment of different potential coastal and flood-risk management options. A multi-attribute value theory is used to calculate the level of impact that different management approaches would have on the most vulnerable historic landscape character areas, the local ecology, economy and community. The Landscape Vulnerability Framework developed in this thesis can be applied to landscapes in the UK and beyond. It will provide a simple, well defined method for policy-makers and heritage organisations to effectively consider the vulnerability of the historic landscape to climate change, and inform a holistic, proactive approach to the sustainable management of cultural heritag

Airspace Systems Program: Next Generation Air Transportation System Concepts and Technology Development FY2010 Project Plan Version 3.0

This document describes the FY2010 plan for the management and execution of the Next Generation Air Transportation System (NextGen) Concepts and Technology Development (CTD) Project. The document was developed in response to guidance from the Airspace Systems Program (ASP), as approved by the Associate Administrator of the Aeronautics Research Mission Directorate (ARMD), and from guidelines in the Airspace Systems Program Plan. Congress established the multi-agency Joint Planning and Development Office (JPDO) in 2003 to develop a vision for the 2025 Next Generation Air Transportation System (NextGen) and to define the research required to enable it. NASA is one of seven agency partners contributing to the effort. Accordingly, NASA's ARMD realigned the Airspace Systems Program in 2007 to "directly address the fundamental research needs of the Next Generation Air Transportation System...in partnership with the member agencies of the JPDO." The Program subsequently established two new projects to meet this objective: the NextGen-Airspace Project and the NextGen-Airportal Project. Together, the projects will also focus NASA s technical expertise and world-class facilities to address the question of where, when, how and the extent to which automation can be applied to moving aircraft safely and efficiently through the NAS and technologies that address optimal allocation of ground and air technologies necessary for NextGen. Additionally, the roles and responsibilities of humans and automation influence in the NAS will be addressed by both projects. Foundational concept and technology research and development begun under the NextGen-Airspace and NextGen-Airportal projects will continue. There will be no change in NASA Research Announcement (NRA) strategy, nor will there be any change to NASA interfaces with the JPDO, Federal Aviation Administration (FAA), Research Transition Teams (RTTs), or other stakeholder

The ecological implications of sea-level rise and storms for sandy beaches in KwaZulu-Natal.

Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2008.The aesthetic appeal of beaches has made coastal properties prime sites for development. However, this development has been mismanaged and is within the littoral active zone. Beaches retreat landwards as sea levels rise, but with current development trends, beaches are trapped in a coastal squeeze. Climate-change predictions include an increase in frequency and heightened intensity of storms, which can cause significant erosion. This study aimed to determine the ecological implications of sea-level rise and storms for beaches in KwaZulu-Natal (KZN), using geographic information systems (GIS) and beach sampling methods. The beaches were mapped in terms of physical and biological attributes. Spatial trends in these attributes showed that the coastline can be split into three – the northern, central and southern regions. Although 25 % of the coastline is protected by marine reserves, these are located in the Delagoa bioregion: 28 macrofauna species in the Natal bioregion are not protected. Storm impacts for beaches can be heterogeneous, depending on local coastal features, e.g., nearshore reef and sand dunes, and represented a temporary disturbance to macrofauna communities. A GIS-based coastal recession model was derived from Bruun’s rule, and applied for different scenarios of sea-level rise and coastal development. Coastal squeeze is concern, particularly in the southern region. Further, the 10-m elevation contour was not completely effective as a setback line, even for a low sea-level rise scenario. The coastal recession model was validated using data from a real event in KZN, where sea level rose temporarily by ~1.0 m. The model performed well, although the calibration possibly did not span a wide enough range of beach morphodynamic types, and under-predicted retreat for dissipative beaches. It was concluded that the Natal bioregion needs marine reserves, and that higher resolution spatial data are required for accurate beach modeling and the south coast railway line should be relocated proactively. Guidelines for sandy beach systematic conservation planning were outlined, and seated in a conceptual framework of managing beaches for resilience. Application of the proposed recommendations and frameworks could aid in determining a way forward in integrated coastal zone management for KZN, in the face of the uncertainties associated with climate change
