Wind Resource Mapping Using Landscape Roughness and Spatial Interpolation Methods

Energy saving, reduction of greenhouse gasses and increased use of renewables are key policies to achieve the European 2020 targets. In particular, distributed renewable energy sources, integrated with spatial planning, require novel methods to optimise supply and demand. In contrast with large scale wind turbines, small and medium wind turbines (SMWTs) have a less extensive impact on the use of space and the power system, nevertheless, a significant spatial footprint is still present and the need for good spatial planning is a necessity. To optimise the location of SMWTs, detailed knowledge of the spatial distribution of the average wind speed is essential, hence, in this article, wind measurements and roughness maps were used to create a reliable annual mean wind speed map of Flanders at 10 m above the Earth’s surface. Via roughness transformation, the surface wind speed measurements were converted into meso- and macroscale wind data. The data were further processed by using seven different spatial interpolation methods in order to develop regional wind resource maps. Based on statistical analysis, it was found that the transformation into mesoscale wind, in combination with Simple Kriging, was the most adequate method to create reliable maps for decision-making on optimal production sites for SMWTs in Flanders (Belgium).

The capacities of institutions for the integration of ecosystem services in coastal strategic planning: The case of Jiaozhou Bay

This paper explains how the practice of integrating ecosystem-service thinking (i.e., ecological benefits for human beings) and institutions (i.e., organisations, policy rules) is essential for coastal spatial planning. Adopting an integrated perspective on ecosystem services (ESs) both helps understand a wide range of possible services and, at the same time, attune institution to local resource patterns. The objective of this paper is to identify the extent to which ESs are integrated in a specific coastal strategic planning case. A subsequent objective is to understand whether institutions are capable of managing ESs in terms of uncovering institutional strengths and weaknesses that may exist in taking ESs into account in existing institutional practices. These two questions are addressed through the application of a content analysis method and a multi-level analysis framework on formal institutions. Jiaozhou Bay in China is used as an illustrative case. The results show that some ESs have been implicitly acknowledged, but by no means the whole range. This partial ES implementation could result from any of four institutional weaknesses in the strategic plans of Jiaozhou Bay, namely a dominant market oriented interest, fragmented institutional structures for managing ESs, limited ES assessment, and a lack of integrated reflection of the social value of ESs in decision-making. Finally, generalizations of multi-level institutional settings on ES integration, such as an inter-organisational fragmentation and a limited use of ES assessment in operation, are made together with other international case studies. Meanwhile, the comparison highlights the influences of extensive market-oriented incentives and governments' exclusive responsibilities on ES governance in the Chinese context.

Climate change adaptation planning under uncertainty in Ho Chi Minh City, Vietnam: a case study on institutional vulnerability, adaptive capacity and climate change governance

Climate change is expected to have wide-ranging impacts on urban areas and creates additional challenges for sustainable development. Urban areas are inextricably linked with climate change, as they are major contributors to it, while also being particularly vulnerable to its impacts. Climate change presents a new challenge to urban areas, not only because of the expected rises in temperature and sea-level, but also the current context of failure to fully address the institutional barriers preventing action to prepare for climate change, or feedbacks between urban systems and agents. Despite the importance of climate change, there are few cities in developing countries that are attempting to address these issues systematically as part of their governance and planning processes. While there is a growing literature on the risks and vulnerabilities related to climate change, as yet there is limited research on the development of institutional responses, the dissemination of relevant knowledge and evaluation of tools for practical planning responses by decision makers at the city level. This thesis questions the dominant assumptions about the capacity of institutions and potential of adaptive planning. It argues that achieving a balance between climate change impacts and local government decision-making capacity is a vital for successful adaptation to the impacts of climate change. Urban spatial planning and wider environmental planning not only play a major role in reducing/mitigating risks but also have a key role in adapting to uncertainty in over future risk. The research focuses on a single province - the biggest city in Vietnam - Ho Chi Minh City - as the principal case study to explore this argument, by examining the linkages between urban planning systems, the structures of governance, and climate change adaptation planning. In conclusion it proposes a specific framework to offer insights into some of the more practical considerations, and the approach emphasises the importance of vertical and horizontal coordination in governance and urban planning.

Descriptions of Scottish Priority Marine Features (PMFs).

Background The seas around Scotland are rich and diverse – Scotland’s position at the edge of the continental shelf, the long coastline, large area of sea and the mixing of warm and coldwater currents combine to make its waters a special place for marine wildlife and habitats. Scotland has over 18,000 km of coastline and its inshore and offshore areas are among the largest of any EU country, representing 13% of all European seas. Scotland’s seas are of outstanding scenic, historical and cultural value and are part of the national identity at home and abroad. The Marine (Scotland) Act 2010 and the UK Marine and Coastal Access Act 2009 include new powers and duties to ensure that our seas are managed sustainably for future generations, integrating the economic growth of marine industries with the need to protect these assets. Measures to conserve Scotland’s marine natural heritage are based on a three pillar approach, with action at the wider seas level (e.g. marine planning or sectoral controls); specific species conservation measures (e.g. improved protection for seals); and through site protection measures - the identification of new Marine Protected Areas (MPAs). To help target action under each of the three pillars, Scottish Natural Heritage (SNH) and the Joint Nature Conservation Committee (JNCC) have generated a focused list of habitats and species of priority conservation importance - the Priority Marine Features (PMFs). The aim of the current study was to produce a descriptive catalogue of the Scottish PMFs (including component habitats and species where appropriate) to serve as a reference for future nature conservation action. Whilst derived from available existing accounts, the succinct 1-page descriptions are written from a Scottish perspective, refining, but clearly linking to more generic UK, EC or OSPAR (Oslo and Paris Commission) commentary. Available information on the geographic distribution of the features was collated as part of the project and a summary map is provided in each description. Main findings  This project has generated a descriptive catalogue of the 81 PMFs that have been identified in the seas around Scotland (out to the limit of the UK continental shelf). The list comprises 26 broad habitats (e.g. burrowed mud), seven low or limited mobility species (e.g. ocean quahog) and 48 mobile species, including fish (e.g. blue ling) and marine mammals (e.g. minke whale).  Information on the distribution of the PMFs was collated within a Geographic Information System (GIS). This is the first time that data about such a diverse range of Scottish marine nature conservation interests have been compiled within a single repository. These data have and will be used in conjunction with other contextual base-mapping to inform the development of nature conservation advice and commentary (e.g. in the production of the Scotland’s Marine Atlas - Baxter et al., 2011).  The feature distribution mapping used in the production of this report is being made available to view online via the National Marine Plan Interactive web portal (NMPi - http://www.gov.scot/Topics/marine/seamanagement/nmpihome). As new or refined data on Scottish PMFs become available, these will be fed into updates to the project geodatabase and NMPi.

Territorial development, planning reform and urban governance: the case of Ireland's second-tier cities

The increased emphasis within Europe on the role of second-tier cities has implications for the ways in which these urban centres are considered within national spatial planning strategies. In centralised, monocentric states like Ireland, there has been a general ambivalence towards urban policy for cities outside the capital city, and historically this has prevented the development of a strong, diversified urban hierarchy undermining prospects for balanced regional development. This paper examines the extent to which a new found emphasis on Ireland’s second-tier cities which emerged in the ‘Gateways’ policy of the National Spatial Strategy (NSS, 2002) was matched by subsequent political and administrative commitment to facilitate the development of these urban centres. Following a discussion of the position of second-tier cities in an international context and a brief overview of recent demographic and economic trends, the paper assesses the relative performance of Ireland’s second-tier cities in influencing development trends, highlighting a comprehensive failure to deliver compact urban growth. In this context, the paper then discusses the implications of current development plans for the second-tier cities and proposals for Irish local government reform for securing compact urban development.

Impact of a 1755-like tsunami in Huelva, Spain

Coastal areas are highly exposed to natural hazards associated with the sea. In all cases where there is historical evidence for devastating tsunamis, as is the case of the southern coasts of the Iberian Peninsula, there is a need for quantitative hazard tsunami assessment to support spatial planning. Also, local authorities must be able to act towards the population protection in a preemptive way, to inform 'what to do' and 'where to go' and in an alarm, to make people aware of the incoming danger. With this in mind, we investigated the inundation extent, run-up and water depths, of a 1755-like event on the region of Huelva, located on the Spanish southwestern coast, one of the regions that was affected in the past by several high energy events, as proved by historical documents and sedimentological data. Modelling was made with a slightly modified version of the COMCOT (Cornell Multi-grid Coupled Tsunami Model) code. Sensitivity tests were performed for a single source in order to understand the relevance and influence of the source parameters in the inundation extent and the fundamental impact parameters. We show that a 1755-like event will have a dramatic impact in a large area close to Huelva inundating an area between 82 and 92 km(2) and reaching maximum run-up around 5 m. In this sense our results show that small variations on the characteristics of the tsunami source are not too significant for the impact assessment. We show that the maximum flow depth and the maximum run-up increase with the average slip on the source, while the strike of the fault is not a critical factor as Huelva is significantly far away from the potential sources identified up to now. We also show that the maximum flow depth within the inundated area is very dependent on the tidal level, while maximum run-up is less affected, as a consequence of the complex morphology of the area.

Soil erosion after forest fires: evaluation of mitigation measures applied to drainage channels in the northwest of Portugal

The development and implementation of measures which promote the reduction of the impacts of forest fires on soils is imperative and should be part of any strategy for forest and soil preservation and recovery, especially considering the actual scenario of continuous growth in the number of fires and burnt area. Consequently, with the dendrocaustologic reality that has characterized the Portuguese mainland in recent decades, a research project promoted by the Center for the Study of Geography and Spatial Planning (CEGOT) was implemented with the objective of applying several erosion mitigation measures in a burned area of the Peneda-Geres National Park in NW Portugal. This paper therefore seeks to present the measures applied in the study area within the project Soil Protec, relating to triggered channel processes and the results of preliminary observations concerning the evaluation of the effectiveness of erosion mitigation measures implemented, as well as their cost/benefit ratio.

As Dinâmicas do Mercado Imobiliário e os Impactos Territoriais

A política de ordenamento do território tem um papel indispensável na promoção da qualidade dos espaços urbanos e da complementaridade entre os diferentes usos do solo. Contudo, a prossecução destes objetivos tem encontrado vários obstáculos. Esta investigação entende como principal obstáculo o impacto que a especulação imobiliária e o respetivo ciclo de expansão-depressão têm no crescimento dos centros urbanos. O método do “estudo de caso” é aplicado ao município do Entroncamento, onde são evidentes os impactos territoriais resultantes do ciclo imobiliário: (i) excesso de loteamentos com execução residual; (ii) PMOT expansionistas e desfasados da realidade económico-demográfica; e (iii) fragmentação do tecido urbano provocado pelo crescimento em extensão da cidade, com aumento dos custos de manutenção dos equipamentos e infraestruturas. Os impactos referidos são comprovados através do “método da avaliação”, utilizado para averiguar a execução das áreas urbanizáveis projetadas pelos PMOT com apoio complementar de informação obtida junto da CME. A abordagem centrada na escala local é antecedida de uma explicação teórica acerca da formação do ciclo de expansão/depressão, a uma escala macro, onde se percebe a influência da especulação imobiliária na origem da recente crise económico-financeira no mundo ocidental. Por último, são defendidas soluções alternativas, que reforcem o poder de regulação do mercado imobiliário, e consequentemente, contribuam para a minimização dos impactos territoriais analisados. A principal solução é a reformulação do imposto sobre a propriedade (escala macro), com o intuito de centrar a tributação no valor do solo, ao invés do valor da construção. Esta medida desincentiva a retenção especulativa do solo, pelo que beneficia a reabilitação urbana das áreas consolidadas e a respetiva colmatação. Ao mesmo tempo, é uma ferramenta fundamental para alcançar os objetivos do ordenamento do território, pois cria as condições necessárias para planear por antecipação o desenvolvimento futuro dos territórios.

"A reserva ecológica nacional e a sua importância para o ordenamento do território"

This work primarily aims to investigate the ambiguity between the right to build and the need to preserve nature through one of its instruments: the National Ecological Reserve. In both national and international political effort, forced by increasing ecological awareness of the society were being created regulations for environmental problemsolving frameworks. This significant increase in provisions, that regulated the environment and spatial territory, are directly related to the objectives of the European community. In a year when the soil policy has changed, it is important to review the priorities of regional planning in the face of environmental policies. REN is a restriction of public utility that, among other things, aims to define and integrate diverse areas of our territory which by their structure are essential to the ecological stability of the environment. Going through a historical study of the various regimes that regulated REN, the present work aims to inform the understanding of the concept REN, exposing its objectives and form of delimitation of integrated areas, in order to answer questions about the nature of this institute. It were related to all regulations governing the ecological reserves and land, namely Scheme for Conservation of Nature and Biodiversity; Natura 2000, the National Agricultural Reserve, the Law of the ownership of water resources and water, and the RJIGT RJUE, checking to its compatibility with REN. Through a literature review regarding the jurisprudence of national courts applying the doctrine, analysis of legal regimes, analysis of maps depicting the REN, we carried out a qualitative assessment of the trend and legal effect of REN in protecting populations and environment. Therefore we will work with this reflect on the existing environment awareness in our society and its problems in the management of natural resources.

Impactos territoriais de processos de cooperação transfronteiriça : caso de estudo : Elvas e Badajoz

A cooperação transfronteiriça é vista na União Europeia como um modelo de integração territorial e como uma alternativa para o desenvolvimento das regiões de fronteira, devido ao seu afastamento em relação aos grandes centros urbanos. No início da década de 90 foi lançado o programa do INTERREG tendo em vista a maior permeabilidade da fronteira e o desenvolvimento destes territórios, entre os quais o das regiões do Alto Alentejo e da Extremadura. A grande proximidade territorial entre Elvas e Badajoz permitiu desde sempre relações de cooperação mais ou menos intensas e consentidas, mesmo antes da abertura da fronteira, motivadas sobretudo pela diferença de valor entre as duas moedas. Contudo, com a entrada conjunta dos países ibéricos na CEE (1986), essas relações intensificaram-se ao nível do comércio, do emprego, do turismo, do lazer e da procura de serviços. Impactos territoriais como a procura e utilização conjunta de infraestruturas e de espaços públicos pelas populações das duas cidades, a promoção e realização de espetáculos culturais, a prática de cross-border shopping, a procura de uma segunda residência, em ambos os lados da fronteira, e a tendência para uma urbanização contínua no futuro, justificaram a criação da Eurocidade Elvas-Badajoz (2013). Esta iniciativa tem como principais objetivos promover a conceção, gestão e prestação conjunta de serviços, desenvolver projetos de cooperação em áreas de interesse comum, estimular a cooperação entre empresas e atrair investimentos geradores de novos postos de trabalho. No entanto os desafios para ambas as cidades prendem-se com a existência de um quadro jurídico e legal distinto que tem condicionado algumas das ações ou iniciativas e o desenvolvimento territorial conjunto ainda carece de uma proposta estratégica.
