Farmland biodiversity and the footprint of agriculture

Sustainable development requires the reconciliation of demands for biodiversity conservation and increased agricultural production. Assessing the impact of novel farming practices on biodiversity and ecosystem services is fundamental to this process. Using farmland birds as a model system, we present a generic risk assessment framework that accurately predicts each species' current conservation status and population growth rate associated with past changes in agriculture. We demonstrate its value by assessing the potential impact on biodiversity of two controversial land uses, genetically modified herbicide-tolerant crops and agri-environment schemes. This framework can be used to guide policy and land management decisions and to assess progress toward sustainability targets.

Overview of an innovative EU-China collaboration in education and research in sustainable built environment

This paper introduces an international collaboration of EU and Asia in education, training and research in the field of sustainable built environment, which attempts to develop a network of practical and intellectual knowledge and training exchange between Chinese and European Universities in the field of sustainable building design and construction. The projects funded by the European Commission Asia Link program, UK Foreign & Commonwealth Office, British Council and the UK Engineering Physical Sciences Council (EPSRC) have been introduced. The projects have significant impacts on promoting sustainable development in built environment in China. The aim of this paper is to share the experiences with those who are interested and searching the ways to collaborate with China in education and research.

Community based ecotourism as a panacea for protected areas: the use of common property theory in its analysis and development

Tourism is the worlds largest employer, accounting for 10% of jobs worldwide (WTO, 1999). There are over 30,000 protected areas around the world, covering about 10% of the land surface(IUCN, 2002). Protected area management is moving towards a more integrated form of management, which recognises the social and economic needs of the worlds finest areas and seeks to provide long term income streams and support social cohesion through active but sustainable use of resources. Ecotourism - 'responsible travel to natural areas that conserves the environment and improves the well- being of local people' (The Ecotourism Society, 1991) - is often cited as a panacea for incorporating the principles of sustainable development in protected area management. However, few examples exist worldwide to substantiate this claim. In reality, ecotourism struggles to provide social and economic empowerment locally and fails to secure proper protection of the local and global environment. Current analysis of ecotourism provides a useful checklist of interconnected principles for more successful initiatives, but no overall framework of analysis or theory. This paper argues that applying common property theory to the application of ecotourism can help to establish more rigorous, multi-layered analysis that identifies the institutional demands of community based ecotourism (CBE). The paper draws on existing literature on ecotourism and several new case studies from developed and developing countries around the world. It focuses on the governance of CBE initiatives, particularly the interaction between local stakeholders and government and the role that third party non-governmental organisations can play in brokering appropriate institutional arrangements. The paper concludes by offering future research directions."

Design and management of sustainable built environments

The United Nation Intergovernmental Panel on Climate Change (IPCC) makes it clear that climate change is due to human activities and it recognises buildings as a distinct sector among the seven analysed in its 2007 Fourth Assessment Report. Global concerns have escalated regarding carbon emissions and sustainability in the built environment. The built environment is a human-made setting to accommodate human activities, including building and transport, which covers an interdisciplinary field addressing design, construction, operation and management. Specifically, Sustainable Buildings are expected to achieve high performance throughout the life-cycle of siting, design, construction, operation, maintenance and demolition, in the following areas: • energy and resource efficiency; • cost effectiveness; • minimisation of emissions that negatively impact global warming, indoor air quality and acid rain; • minimisation of waste discharges; and • maximisation of fulfilling the requirements of occupants’ health and wellbeing. Professionals in the built environment sector, for example, urban planners, architects, building scientists, engineers, facilities managers, performance assessors and policy makers, will play a significant role in delivering a sustainable built environment. Delivering a sustainable built environment needs an integrated approach and so it is essential for built environment professionals to have interdisciplinary knowledge in building design and management . Building and urban designers need to have a good understanding of the planning, design and management of the buildings in terms of low carbon and energy efficiency. There are a limited number of traditional engineers who know how to design environmental systems (services engineer) in great detail. Yet there is a very large market for technologists with multi-disciplinary skills who are able to identify the need for, envision and manage the deployment of a wide range of sustainable technologies, both passive (architectural) and active (engineering system),, and select the appropriate approach. Employers seek applicants with skills in analysis, decision-making/assessment, computer simulation and project implementation. An integrated approach is expected in practice, which encourages built environment professionals to think ‘out of the box’ and learn to analyse real problems using the most relevant approach, irrespective of discipline. The Design and Management of Sustainable Built Environment book aims to produce readers able to apply fundamental scientific research to solve real-world problems in the general area of sustainability in the built environment. The book contains twenty chapters covering climate change and sustainability, urban design and assessment (planning, travel systems, urban environment), urban management (drainage and waste), buildings (indoor environment, architectural design and renewable energy), simulation techniques (energy and airflow), management (end-user behaviour, facilities and information), assessment (materials and tools), procurement, and cases studies ( BRE Science Park). Chapters one and two present general global issues of climate change and sustainability in the built environment. Chapter one illustrates that applying the concepts of sustainability to the urban environment (buildings, infrastructure, transport) raises some key issues for tackling climate change, resource depletion and energy supply. Buildings, and the way we operate them, play a vital role in tackling global greenhouse gas emissions. Holistic thinking and an integrated approach in delivering a sustainable built environment is highlighted. Chapter two demonstrates the important role that buildings (their services and appliances) and building energy policies play in this area. Substantial investment is required to implement such policies, much of which will earn a good return. Chapters three and four discuss urban planning and transport. Chapter three stresses the importance of using modelling techniques at the early stage for strategic master-planning of a new development and a retrofit programme. A general framework for sustainable urban-scale master planning is introduced. This chapter also addressed the needs for the development of a more holistic and pragmatic view of how the built environment performs, , in order to produce tools to help design for a higher level of sustainability and, in particular, how people plan, design and use it. Chapter four discusses microcirculation, which is an emerging and challenging area which relates to changing travel behaviour in the quest for urban sustainability. The chapter outlines the main drivers for travel behaviour and choices, the workings of the transport system and its interaction with urban land use. It also covers the new approach to managing urban traffic to maximise economic, social and environmental benefits. Chapters five and six present topics related to urban microclimates including thermal and acoustic issues. Chapter five discusses urban microclimates and urban heat island, as well as the interrelationship of urban design (urban forms and textures) with energy consumption and urban thermal comfort. It introduces models that can be used to analyse microclimates for a careful and considered approach for planning sustainable cities. Chapter six discusses urban acoustics, focusing on urban noise evaluation and mitigation. Various prediction and simulation methods for sound propagation in micro-scale urban areas, as well as techniques for large scale urban noise-mapping, are presented. Chapters seven and eight discuss urban drainage and waste management. The growing demand for housing and commercial developments in the 21st century, as well as the environmental pressure caused by climate change, has increased the focus on sustainable urban drainage systems (SUDS). Chapter seven discusses the SUDS concept which is an integrated approach to surface water management. It takes into consideration quality, quantity and amenity aspects to provide a more pleasant habitat for people as well as increasing the biodiversity value of the local environment. Chapter eight discusses the main issues in urban waste management. It points out that population increases, land use pressures, technical and socio-economic influences have become inextricably interwoven and how ensuring a safe means of dealing with humanity’s waste becomes more challenging. Sustainable building design needs to consider healthy indoor environments, minimising energy for heating, cooling and lighting, and maximising the utilisation of renewable energy. Chapter nine considers how people respond to the physical environment and how that is used in the design of indoor environments. It considers environmental components such as thermal, acoustic, visual, air quality and vibration and their interaction and integration. Chapter ten introduces the concept of passive building design and its relevant strategies, including passive solar heating, shading, natural ventilation, daylighting and thermal mass, in order to minimise heating and cooling load as well as energy consumption for artificial lighting. Chapter eleven discusses the growing importance of integrating Renewable Energy Technologies (RETs) into buildings, the range of technologies currently available and what to consider during technology selection processes in order to minimise carbon emissions from burning fossil fuels. The chapter draws to a close by highlighting the issues concerning system design and the need for careful integration and management of RETs once installed; and for home owners and operators to understand the characteristics of the technology in their building. Computer simulation tools play a significant role in sustainable building design because, as the modern built environment design (building and systems) becomes more complex, it requires tools to assist in the design process. Chapter twelve gives an overview of the primary benefits and users of simulation programs, the role of simulation in the construction process and examines the validity and interpretation of simulation results. Chapter thirteen particularly focuses on the Computational Fluid Dynamics (CFD) simulation method used for optimisation and performance assessment of technologies and solutions for sustainable building design and its application through a series of cases studies. People and building performance are intimately linked. A better understanding of occupants’ interaction with the indoor environment is essential to building energy and facilities management. Chapter fourteen focuses on the issue of occupant behaviour; principally, its impact, and the influence of building performance on them. Chapter fifteen explores the discipline of facilities management and the contribution that this emerging profession makes to securing sustainable building performance. The chapter highlights a much greater diversity of opportunities in sustainable building design that extends well into the operational life. Chapter sixteen reviews the concepts of modelling information flows and the use of Building Information Modelling (BIM), describing these techniques and how these aspects of information management can help drive sustainability. An explanation is offered concerning why information management is the key to ‘life-cycle’ thinking in sustainable building and construction. Measurement of building performance and sustainability is a key issue in delivering a sustainable built environment. Chapter seventeen identifies the means by which construction materials can be evaluated with respect to their sustainability. It identifies the key issues that impact the sustainability of construction materials and the methodologies commonly used to assess them. Chapter eighteen focuses on the topics of green building assessment, green building materials, sustainable construction and operation. Commonly-used assessment tools such as BRE Environmental Assessment Method (BREEAM), Leadership in Energy and Environmental Design ( LEED) and others are introduced. Chapter nineteen discusses sustainable procurement which is one of the areas to have naturally emerged from the overall sustainable development agenda. It aims to ensure that current use of resources does not compromise the ability of future generations to meet their own needs. Chapter twenty is a best-practice exemplar - the BRE Innovation Park which features a number of demonstration buildings that have been built to the UK Government’s Code for Sustainable Homes. It showcases the very latest innovative methods of construction, and cutting edge technology for sustainable buildings. In summary, Design and Management of Sustainable Built Environment book is the result of co-operation and dedication of individual chapter authors. We hope readers benefit from gaining a broad interdisciplinary knowledge of design and management in the built environment in the context of sustainability. We believe that the knowledge and insights of our academics and professional colleagues from different institutions and disciplines illuminate a way of delivering sustainable built environment through holistic integrated design and management approaches. Last, but not least, I would like to take this opportunity to thank all the chapter authors for their contribution. I would like to thank David Lim for his assistance in the editorial work and proofreading.

Normative, systemic and procedural aspects: a review of indicator-based sustainability assessments in agriculture

Methods for assessing the sustainability of agricultural systems do often not fully (i) take into account the multifunctionality of agriculture, (ii) include multidimensionality, (iii) utilize and implement the assessment knowledge and (iv) identify conflicting goals and trade-offs. This chapter reviews seven recently developed multidisciplinary indicator-based assessment methods with respect to their contribution to these shortcomings. All approaches include (1) normative aspects such as goal setting, (2) systemic aspects such as a specification of scale of analysis and (3) a reproducible structure of the approach. The approaches can be categorized into three typologies: first, top-down farm assessments, which focus on field or farm assessment; second, top-down regional assessments, which assess the on-farm and the regional effects; and third, bottom-up, integrated participatory or transdisciplinary approaches, which focus on a regional scale. Our analysis shows that the bottom-up, integrated participatory or transdisciplinary approaches seem to better overcome the four shortcomings mentioned above.

Integrating Sustainability into Brownfield Regeneration: Rhetoric or Reality? – An Analysis of the UK Development Industry

In the UK and elsewhere the use of the term ‘sustainable brownfield regeneration’ has resulted from the interweaving of two key policy themes, comprising ‘sustainable development��� and ‘brownfield regeneration’. This paper provides a critical overview of brownfield policy within the context of the emerging sustainable development agenda in the UK, and examines the development industry's role and attitudes towards key aspects of sustainable development and brownfield regeneration. The paper analyses results from a survey of commercial and residential developers carried out in mid‐2004, underpinned by structured interviews with eleven developers in 2004–2005, which form part of a two‐and‐half‐year EPSRC‐funded project. The results suggest that despite the increasing focus on sustainability in government policy, the development industry seems ill at ease with precisely how sustainable development can be implemented in brownfield schemes. These and other findings, relating to sustainability issues (including the impact of climate change on future brownfield development), have important ramifications for brownfield regeneration policy in the UK. In particular, the research highlights the need for better metrics and benchmarks to be developed to measure ‘sustainable brownfield regeneration’. There also needs to be greater awareness and understanding of alternative clean‐up technologies to ‘dig and dump’.

An analysis of the UK development industry's role in brownfield regeneration

Purpose – This study aims to provide a review of brownfield policy and the emerging sustainable development agenda in the UK, and to examine the development industry’s (both commercial and residential) role and attitudes towards brownfield regeneration and contaminated land. Design/methodology/approach – The paper analyses results from a two-stage survey of commercial and residential developers carried out in mid-2004, underpinned by structured interviews with 11 developers. Findings – The results suggest that housebuilding on brownfield is no longer the preserve of specialists, and is now widespread throughout the industry in the UK. The redevelopment of contaminated sites for residential use could be threatened by the impact of the EU Landfill Directive. The findings also suggest that developers are not averse to developing on contaminated sites, although post-remediation stigma remains an issue. The market for warranties and insurance continues to evolve. Research limitations/implications – The survey is based on a sample which represents nearly 30 per cent of UK volume housebuilding. Although the response in the smaller developer groups was relatively under-represented, non-response bias was not found to be a significant issue. More research is needed to assess the way in which developers approach brownfield regeneration at a local level. Practical implications – The research suggests that clearer Government guidance in the UK is needed on how to integrate concepts of sustainability in brownfield development and that EU policy, which has been introduced for laudable aims, is creating tensions within the development industry. There may be an emphasis towards greenfield development in the future, as the implications of the Barker review are felt. Originality/value – This is a national survey of developers’ attitudes towards brownfield development in the UK, following the Barker Review, and highlights key issues in UK and EU policy layers.

Learning CSR for sustainable corporate advantage

Corporate Social Responsibility (CSR) has become a strategic and operational reality of the business and academic world. Not that the principles of CSR are always respected or that its practice is consistently applied. Bearing in mind the multi-faceted nature of both CSR and the corporate environment, as well as the paradox of what is taught in Higher Education and what is practised within its own walls, this paper provides a learning cyclical pathway to sustainable CSR implementation and progress review. As well as highlighting the role that Higher Education has to play, the paper emphasises that in order to embed CSR within the corporate environment, questions need to be raised concerning on-going CSR improvement in order to both protect and engage a wide range of stakeholders towards sustainable corporate advantage.

Florestas e Desenvolvimento Sustentável: A Gestão de Políticas das Florestas do Gabão

O objetivo principal deste trabalho é investigar de que forma as populações tradicionais são uma ameaça ou resistência ao desmatamento no Gabão , África. Na ótica de um estudo de caso, analisa-se o direito tradicional de propriedade de terra , da política florestal do Gabão, e a organização social e econômica das populações rurais, com o intuito de estabelecer uma relação entre esses elementos e o desenvolvimento sustentável das florestas. Finalmente, demonstramos que a proteção das florestas tropicais é compatível com as regras do direito tradicional de propriedade das aldeias. O direito ocidental pode ajudar a proteger ou destruir as florestas , dependendo de como é usado.

Agricultura ecológica : do engajamento possível à retribuição esperada : um estudo dos agricultores ecologistas de Antônio Prado e Ipê-RS

Nesta dissertação, analiso as lógicas de engajamento dos agricultores ecologistas na agricultura ecológica em Antônio Prado e Ipê, ambos municípios da Encosta Superior do Nordeste do Rio Grande do Sul, Brasil. Os diferentes graus de engajamento dos agricultores estão relacionados à heterogeneidade na estrutura e volume de capitais acumulados por esses agentes durante suas trajetórias e às distintas expectativas de retribuição com relação a este referencial de agricultura. O referencial foi construído ou socializado neste cenário, principalmente, pelos técnicos do Centro Ecológico, constituindo-se num conjunto de práticas agrícolas alternativas que pretendem viabilizar avanços sustentáveis na produção agrícola. Na busca destes “avanços”, a agricultura ecológica é construída sob uma dimensão simbólica, orientada “pela filosofia da preservação ambiental e da justiça social”, e uma dimensão econômica caracterizada pelo objetivo de viabilizar econômica e socialmente a agricultura familiar. Assim, os agricultores, ao se engajarem, fazem suas releituras do referencial e, pela socialização, vão incorporando os limites impostos as suas ações pelas representações dominantes (legítimas) da “prática” e pelas normas que vão se institucionalizando ao longo do tempo, resultando na estrutura objetiva do espaço de relações da agricultura ecológica na região. Essas releituras resultam em distintos graus de engajamento. As distintas tomadas de posições e estratégias desenvolvidas pelos agricultores ecologistas possibilitam a formação de uma hierarquia normativa neste espaço social, permitindo que alguns agricultores, devido às disposições incorporadas durante suas trajetórias e ao tipo de relação estabelecida com os técnicos, se tornem novos mediadores.

Economia dos recursos naturais, desenvolvimento sustentável e teoria do crescimento econômico : uma aplicação para o Brasil

Este trabalho tem como meta uma exposição sucinta sobre as relações entre economia e meio ambiente, que foram, durante muito tempo, ignoradas ou relegadas a um plano secundário pela grande maioria dos economistas. Essas relações passaram a ser melhor investigadas após os choques do petróleo na década de 70, que mudaram radicalmente o enfoque sobre o binômio economia-meio ambiente, contribuindo também para essa mudança os efeitos cada vez mais visíveis causados pela poluição desenfreada do planeta. Discute-se também sobre o conceito de desenvolvimento sustentável, bem como sobre sua evolução ao longo do tempo e as duas visões concorrentes sobre essa questão, além de abordar, resumidamente, a qualidade ambiental e os recursos naturais de propriedade comum como bens públicos. O trabalho também traça um paralelo entre os modelos de crescimento neoclássicos e os modelos de crescimento endógeno, no que se refere à incorporação de variáveis ambientais, como poluição, energia e recursos naturais. Como contribuição empírica para a conexão entre capital natural e crescimento econômico, procuramos estimar a relação entre estoque de terras, empregado como proxy para o capital natural, e o crescimento da renda per capita para as unidades federativas brasileiras, a partir de 1970, por meio de uma relação cúbica empregando dados de painel. Verificamos que, quando se consideram, para o cálculo do índice de expansão agrícola, os dados referentes à área agrícola utilizada, que é a soma da área agrícola permanente mais a área agrícola temporária, o modelo empregado é significativo e bem especificado. Neste caso, constatamos um padrão de “explosão e quebra” do processo de crescimento econômico associado à expansão da lavoura agrícola das unidades federativas brasileiras.

Gestão social do desenvolvimento: a exclusão dos representantes dos empresários? o caso do programa Territórios da Cidadania norte-RJ

A incorporação do enfoque territorial como fundamento para as políticas de desenvolvimento rural ocasionou, dentre outros avanços, no rompimento com a tradição vertical e centralizadora das estratégias de desenvolvimento, e na consequente valorização das iniciativas e dos atores locais. Tal abordagem acolhe a gestão social, e seus princípios da inclusão, relativo à incorporação dos atores excluídos do processo decisório, e do pluralismo, que diz respeito à multiplicidade de atores na tomada de decisões sobre as políticas públicas. No caso brasileiro, o enfoque territorial é encampado pelo Programa de Desenvolvimento Sustentável dos Territórios Rurais e pelo seu sucessor, o Programa Territórios da Cidadania. No entanto, a trajetória das políticas de desenvolvimento rural é francamente setorial, ao privilegiar as organizações vinculadas à agricultura familiar e excluir as organizações representantes dos empresários, apesar dos princípios portados pela gestão social e da adoção da abordagem territorial, que implicam na mobilização das forças sociais dinâmicas presentes nos territórios. Assim, considerada a importância da participação empresarial para o êxito das políticas dessa natureza, este trabalho analisa as possibilidades de inclusão das representações dos empresários para o pluralismo no âmbito do Programa Territórios da Cidadania. Para tanto, realizou-se um estudo de caso no Norte- RJ, no qual foram entrevistados representantes da sociedade civil, dos empresários, do SEBRAE e do Ministério do Desenvolvimento Agrário, cujas informações foram complementadas por análise documental, e tratadas por meio de análise de conteúdo com grade mista elaborada com base no conceito de cidadania deliberativa habermasiano. Os resultados relevam que as representações empresariais não estão inseridas no colegiado territorial do Norte-RJ, e tampouco conhecem o Programa Territórios da Cidadania. As entidades da sociedade civil, que consideram o colegiado como Fórum da Agricultura Familiar, rechaçam indistintamente a inclusão dos empresários por conta de diferenças sócio-políticas, agravadas pelo histórico da região. O pluralismo também é atravancado pelos processos de formação do território, de composição do colegiado e de elaboração e avaliação dos projetos. As representações empresariais, por seu turno, já estão inseridas em outras instâncias de participação social, como conselhos municipais de políticas públicas, e aceitam a dinâmica que rege estes espaços pautados na racionalidade substantiva. Sua inserção pode ser facilitada pelo SEBRAE/RJ que, além de gozar de prestígio dentre os empresários, tem fomentado a articulação dos atores territoriais. Não obstante as possibilidades para a inclusão, o modelo de gestão social em vigor não é capaz de promover a concertação social das forças dinâmicas em prol do desenvolvimento do território Norte-RJ.

Sustainable silvopastoral systems: theory and a practical case

Muitas transformações são esperadas por causa das mudanças do clima, especialmente das atividades agrícolas realizadas nos trópicos. Esta tese centra-se em dois aspectos. O primeiro deles é o de reunir o conhecimento de sistemas silvipastoris; este ponto de vista estabelece a importância de solos tropicais e sua gestão adequada de acordo com as normas ambientais e sustentáveis. A segunda parte da tese é a aplicação desses princípios em um caso específico: a fazenda "El Paraíso". O objetivo central ou problema a resolver da segunda parte é propor um projeto para melhorar as atividades de produção de carne e, ao mesmo tempo, ajudar a preservar e melhorar o meio ambiente e especialmente os ecossistemas tropicais. A metodologia utilizada na tese foi buscar e analisar informações sobre o assunto. Depois disso, a investigação experimental e de campo foi realizada para levantar o projeto que combinaria as duas partes da obra. No final, com a informação recolhida uma proposta de projeto foi feita. O objetivo era propor a transformação dos processos de produção na fazenda selecionada. Logo de desenvolver e apresentar o projeto, foram analisadas as possibilidades de implementação do projeto. A conclusão do estudo foi o de apresentar e discutir três cenários possíveis após a implementação. Finalmente, a conclusão geral apresenta as realizações, as oportunidades e possíveis expansões futuras do projeto.
