People and their past : is 'community archaeology’ the future?

This thesis looks at how ‘community archaeology’ ideals may influence an inclusive approach to Indigenous heritage management, ensuring Indigenous community power over processes to identify both past and present values of Country. Community archaeology was acclaimed by research archaeologists over a decade ago as a distinctive approach with its own set of practices to incorporate the local community’s perspectives of its past and current associations with place. A core feature of this approach in Australia is the major role the Indigenous community has in decisions about its heritage. Concurrently, considerable concern was being expressed that Indigenous heritage was not sufficiently addressed in environmental impact assessment processes ahead of development. Seen as absent from the process was the inclusion of Indigenous knowledge about both the pre- and post-contact story as well as any scientific advance in understanding an area’s Indigenous history. This research examines these contrasting perspectives seeking to understand the ideals of community archaeology and its potential to value all aspects of Indigenous heritage and so benefit the relevant community. The ideals of community archaeology build on past community collaborations in Australia and also respond to more recent societal recognition of Indigenous rights, reflected in more ethically inclusive planning and heritage statutes. Indigenous communities expressed the view that current systems are still not meeting these policy commitments to give them control over their heritage. This research has examined the on-the-ground reality of heritage work on the outskirts of Canberra and Melbourne. The case studies compare Victorian and ACT heritage management processes across community partnerships with public land managers, and examine how pre-development surveys operate. I conclude that considerable potential for achieving community archaeology ideals exists, and that they are occasionally partially realised, however barriers continue. In essence, the archaeological model persists despite a community archaeology approach requiring a wider set of skills to ensure a comprehensive engagement with an Indigenous community. Other obstacles in the current Indigenous heritage management system include a lack of knowledge and communication about national standards for heritage processes in government agencies and heritage consultants; the administrative framework that can result in inertia or silos between relevant agencies; and funding timeframes that limit possibilities for long-term strategic programs for early identification and management planning for Indigenous heritage. Also, Indigenous communities have varying levels of authority to speak for how their heritage should be managed, yet may not have the resources to do so. This thesis suggests ways to breach these barriers to achieve more inclusive Indigenous heritage management based on community archaeology principles. Policies for a greater acknowledgement of the Indigenous community’s authority to speak for Country; processes that enable and early and comprehensive ‘mapping’ of Country, and long-term resourcing of communities, may have been promised before. In this research I suggest ways to realise such goals.

Different approaches to municipal solid waste management in Brazil : case study Rio de Janeiro

Inadequate final disposal of municipal solid waste (MSW) is associated with significant greenhouse gas (GHG) emission, environmental, health and safety issues, space consumption, public health and developmental issues in general. The environmental impact of waste is mostly felt in developing countries, inadequate waste management and treatment solution, inadequate policies and outdated practices are some of the factors leading to the significantly high final disposal of waste in dumps in developing countries. Brazil and other developing countries are changing the status quo by adopting polices that will adequately address this problem of inadequate waste management and disposal. Life cycle analysis (LCA) identifies the potential environmental impact of a product though environmental impact assessment, International Organization for Standardization (ISO) created the ISO 14040 and ISO 14044 to serve as principle guidelines for conducting LCA. Various waste treatment solution was applied to identify the waste management solution with the least Global warming potential (GWP) for treating the MSW generated from the city of Rio de Janerio, while reducing significantly final waste disposed in landfill.

Fine tuning for the tropics: application of eDNA technology for invasive fish detection in tropical freshwater ecosystems

Invasive species pose a major threat to aquatic ecosystems. Their impact can be particularly severe in tropical regions, like those in northern Australia, where >20 invasive fish species are recorded. In temperate regions, environmental DNA (eDNA) technology is gaining momentum as a tool to detect aquatic pests, but the technology's effectiveness has not been fully explored in tropical systems with their unique climatic challenges (i.e. high turbidity, temperatures and ultraviolet light). In this study, we modified conventional eDNA protocols for use in tropical environments using the invasive fish, Mozambique tilapia (Oreochromis mossambicus) as a detection model. We evaluated the effects of high water temperatures and fish density on the detection of tilapia eDNA, using filters with larger pores to facilitate filtration. Large-pore filters (20 μm) were effective in filtering turbid waters and retaining sufficient eDNA, whilst achieving filtration times of 2-3 min per 2-L sample. High water temperatures, often experienced in the tropics (23, 29, 35 °C), did not affect eDNA degradation rates, although high temperatures (35 °C) did significantly increase fish eDNA shedding rates. We established a minimum detection limit for tilapia (1 fish/0.4 megalitres/after 4 days) and found that low water flow (3.17 L/s) into ponds with high fish density (>16 fish/0.4 megalitres) did not affect eDNA detection. These results demonstrate that eDNA technology can be effectively used in tropical ecosystems to detect invasive fish species. © 2016 John Wiley & Sons Ltd.

Padronização e flexibilidade: proposta de um edifício tipo para uma escola técnica profissionalizante

Nowadays the acquisition of sustainable elements and concepts in construction has been increasingly discussed, improved and incorporated to buildings, since the sector directly interferes in the urban space and environment, representing environmental impact. In order to make a sustainable building (Green Building) it is vital to incorporate less damaging constructive practice, starting from the project until the operation of the enterprise, that means to consider an integrated process of conception, implementation, construction and operation. The more effective sustainable principles participation in architecture happens at the projecting step through minimal environment impact solutions. Among the issues varieties that goes with sustainability proposal of the buildings project, there were added to this work the elements that are directly attached to bioclimatic architecture, more specifically the climate variation, ventilation, lighting and sunlight, that directly affect the project conception. It is important to put in evidence that architecture role goes far beyond the simple activity of building spaces; it is the sequence of political, economic, social and cultural elements, having the users as the main apparatus to its materialization. Thereby this professional dissertation consists of an architecture draft for a professional and technological school in the Rio Grande do Norte State, this dissertation is based on the analysis of previous experience and the bioclimatic principles that implicate in building on hot and dry, hot and humid climates, and the use of strategic solutions that aim the optimization of natural light and ventilation

Comparison of growth traits between abundant and uncommon forms of a non-native vine, Dolichandra unguis-cati (Bignoniaceae) in Australia

Cat’s claw creeper vine, Dolichandra unguis-cati (L.) Lohmann (syn. Macfadyena unguis-cati (L.) Gentry) (Bignoniaceae), is a major environmental weed in Australia. Two distinct forms of this weed (‘long’ and ‘short’ pod), with differences in leaf morphology and fruit size, occur in Australia. The long pod form has only been reported in less than fifteen localities in the whole of south-east Queensland, while the short pod form is widely distributed in Queensland and New South Wales. This study sought to compare growth traits such as specific leaf area, relative growth rate, stem length, shoot/root ratio, tuber biomass and branching architecture between these forms. These traits were monitored under glasshouse conditions over a period of 18 months. Short pod exhibited higher values of relative growth rates, stem length, number of tubers and specific leaf area than long pod, but only after 10 months of plant growth. Prior to this, long and short pod did not differ significantly. Higher values for these traits have been described as characteristics of successful colonizers. Results from this study could partly explain why the short pod form is more widely distributed in Australia while long pod is confined to a few localities.

Preventing weed spread: a survey of lifestyle and commercial landholders about Nassella trichotoma in the Northern Tablelands of New South Wales, Australia

Nassella trichotoma (Nees) Hack. ex Arechav. (common name, serrated tussock) occupies large areas of south-eastern Australia and has considerable scope for expansion in the Northern Tablelands of New South Wales. This highly invasive grass reduces pasture productivity and has the potential to severely affect the region’s economy by decreasing the livestock carrying capacity of grazing land. Other potential consequences of this invasion include increased fuel loads and displacement of native plants, thereby threatening biodiversity. Rural property owners in the Northern Tablelands were sent a mail questionnaire that examined use of measures to prevent new outbreaks of the weed. The questionnaire was sent to professional farmers as well as lifestyle farmers (owners of rural residential blocks and hobby farms) and 271 responses were obtained (a response rate of 18%). Key findings were respondents’ limited capacity to detect N. trichotoma, and low adoption of precautions to control seed spread by livestock, vehicles and machinery. This was particularly the case among lifestyle farmers. There have been considerable recent changes to biosecurity governance arrangements in New South Wales, and now is an ideal time for regulators and information providers to consider how to foster regional communities’ engagement in biosecurity, including the adoption of measures that have the capacity to curtail the spread of N. trichotoma.

Dingoes at the Doorstep: Home Range Sizes and Activity Patterns of Dingoes and Other Wild Dogs around Urban Areas of North-Eastern Australia

Top-predators around the world are becoming increasingly intertwined with humans, sometimes causing conflict and increasing safety risks in urban areas. In Australia, dingoes and dingo � domestic dog hybrids are common in many urban areas, and pose a variety of human health and safety risks. However, data on urban dingo ecology is scant. We GPS-collared 37 dingoes in north-eastern Australia and continuously monitored them each 30 min for 11–394 days. Most dingoes were nocturnal, with an overall mean home range size of 17.47 km2. Overall mean daily distance travelled was 6.86 km/day. At all times dingoes were within 1000 m of houses and buildings. Home ranges appeared to be constrained to patches of suitable vegetation fragments within and around human habitation. These data can be used to reallocate dingo management effort towards mitigating actual conflicts between humans and dingoes in urban areas.

Avaliação de Impacto Ambiental, Valorização do Efluente e dos Resíduos Sólidos da Indústria Corticeira

A preocupação com o meio ambiente, nomeadamente na descarga de águas residuais, consumo de água excessivo e produção de resíduos industriais, está cada vez mais presente no quotidiano. Devido a estas problemáticas, efetuou-se a avaliação de impacte ambiental (AIA) do processo produtivo das rolhas de cortiça naturais, tratamento das águas de cozedura da cortiça (estudo da possível reutilização do efluente tratado) e valorização de subprodutos – resíduo sólido (raspa de cortiça), sendo estes os objetivos propostos para a realização da presente dissertação. Na AIA, efetuada no decorrer das fases da Análise do Ciclo de Vida (ACV), foram selecionadas 8 categorias de impacte – aquecimento global, acidificação, dessecação, toxicidade e ecotoxicidade, eutrofização, consumo de recursos não renováveis e oxidação foto-química. A água de cozedura caracterizou-se por uma elevada carga poluente, apresentando elevada concentração de cor, Carência Química de Oxigénio (CQO), taninos e lenhina e Sólidos Suspensos Totais (SST). O processo de tratamento proposto consistiu num pré-tratamento por ultrafiltração (UF), com membranas de 30.000 e 20.000 MWCO, seguido de adsorção por carvão ativado (comercial e produzido a partir de raspa de cortiça). No tratamento por UF, utilizando uma membrana de 30.000 MWCO, foram obtidas percentagens de remoção para a primeira amostra de água de cozedura de 74,8 % para a cor, 33,1 % para a CQO e para a segunda amostra de 85,2 % para a cor e 41,8 % para a CQO. Posteriormente, apenas para a segunda amostra de água de cozedura e com uma membrana de 20.000 MWCO, as percentagens de remoção obtidas foram superiores, de 93% para a cor, 68,9 % para a CQO, 88,4 % para taninos e lenhina e 43,0 % para azoto total. No tratamento por adsorção com carvão ativado estudou-se o tempo de equilíbrio do carvão ativado comercial e do carvão ativado produzido a partir de aparas de cortiça, seguindo-se o estudo das isotérmicas de adsorção, no qual foram analisados os parâmetros da cor e CQO para cada solução. Os ajustes dos modelos teóricos aos pontos experimentais demonstraram que ambos os modelos (Langmuir e Freundlich) poderiam ser considerados, uma vez que apresentaram ajustes idênticos. Relativamente ao tratamento de adsorção em contínuo do permeado, obtido por UF com membrana de 20.000 MWCO, constatou-se que ambos os carvões ativados (comercial e produzido) não ficaram saturados, tendo em consideração os tempos de saturação estimados pela capacidade máxima de adsorção (determinada para a isotérmica de Langmuir) e as representações gráficas dos valores experimentais obtidos para cada ensaio. No ensaio de adsorção com carvão ativado comercial verificou-se que o efluente tratado poderia ser descarregado no meio hídrico ou reutilizado no processo industrial (considerando os parâmetros analisados), uma vez que até aos 11 minutos de ensaio a concentração da solução à saída foi de 111,50 mg/L O2, para a CQO, e incolor, numa diluição de 1:20. Em relação à adsorção em contínuo com carvão ativado produzido verificou-se no ensaio 4 que o efluente resultante apresentou uma concentração de CQO de 134,5 mg/L O2 e cor não visível, numa diluição de 1:20, ao fim de 1h22 min de ensaio. Assim, concluiu-se que os valores obtidos são inferiores aos valores limite de emissão (VLE) presentes no Decreto-Lei n.º 236/98 de 1 de Agosto. O carvão ativado produzido apresentou elevada área superficial específica, com 870 m2/g, comparativamente ao carvão comercial que foi de 661 m2/g. O processo de extração da suberina a partir de raspa de cortiça isenta de extraíveis, efetuado através da metanólise alcalina, apresentou percentagens de extração superiores aos restantes métodos. No processo efetuado em scale-up, por hidrólise alcalina, obteve-se uma extração de 3,76 % de suberina. A aplicação da suberina no couro demonstrou que esta cera apresenta enormes potencialidades, uma vez que a sua aplicação confere ao couro um aspeto sedoso, com mais brilho e um efeito de “pull-up”.

Yhteisneuvottelu ja viranomaisyhteistyö ympäristöasioissa : YVA- ja lupamenettelyjen yhteyden vahvistaminen

Tähän raporttiin on koottu Uudenmaan ELY-keskuksen ja Etelä-Suomen aluehallintoviraston (AVI) yhteisen, YVA- ja ympäristölupa-menettelyjen yhteyttä edistävän kokeiluhankkeen ensimmäisen vaiheen (9 / 2015 – 8 / 2016) tulokset. Tavoitteena on ollut mm. selvittää ympäristövaikutusten arviointia (YVA), ympäristölupaa ja mahdollista kemikaaliturvallisuuslupaa edellyttävien hankkeiden etenemis-tä nopeuttavia käytäntöjä sekä keinoja parantaa viranomaisten välistä yhteistyötä. YVA- ja lupamenettelyjen ohella tarkasteltiin kaavoitusmenettelyä ja kaavoituksen liittymäpintoja muihin ympäristömenettelyihin. Tiedonkeruumenetelminä käytettiin haastatteluja, kyselyjä ja käytännön kokeiluja. Keskeinen tarkasteltu käytäntö oli toiminnanharjoittajan ja eri viranomaisten välinen yhteisneuvottelu. Neuvottelun tavoitteena on toiminnanharjoittajan hankkeeseen liittyvien YVA-, lupa-, Natura-arviointi-, ja kaavoitusmenettelyjen yhteensovittaminen. Lisäksi neuvottelussa on tarkoitus tunnistaa hankkeeseen liittyviä (ympäristö)selvitystarpeita sekä mahdollisuuksia parantaa yhteistyötä ja tiedonvaihtoa hankkeen kanssa tekemisissä olevien tahojen välillä. Vastaavantyyppisistä neuvotteluista on aiemmissa selvityksissä käytetty termiä ennakkoneuvottelu. Yhteisneuvotteluja voidaan järjestää hankkeen ja siihen liittyvien viranomaismenettelyjen eri vaiheissa. Neuvottelujen määrä, ajoittuminen ja osallistujat suunnitellaan tapauskohtaisesti, hankkeen tarpeista ja siihen liittyvistä viranomaismenettelyistä riippuen. Kaikissa hankkeissa yhteisneuvotteluja ei välttämättä tarvita. Tulosten perusteella raportissa suositellaan viranomaisten välisen yhteistyön parantamista mm. verkostoitumisen ja tiiviimmän yhteydenpidon keinoin. Samoin suositellaan viranomaismenettelyjen yhteensovittamista yhteisneuvottelujen avulla, menettelyjen tiiviimmän yhdistämisen kokeiluja, toiminnan asiakaslähtöisyyden lisäämistä ja viranomaistiedon saatavuuden parantamista. Neuvottelujen onnistumiseksi osallistujilta edellytetään luottamusta, yhteistyöhalukkuutta sekä vastuunottoa yhteensovittamiselle asetettujen tavoitteiden saavuttamisesta. Lisäksi suositellaan, että yhteisneuvottelu säädetään lailla joustavaksi ja tapauskohtaisen harkinnan mahdollistavaksi. Kokeiluhankkeen toisessa vaiheessa (9 / 2016 – 2 / 2017) selvitetään tarkemmin YVA- ja lupamenettelyjen yhteyden vahvistamista ja viranomaisyhteistyön parantamismahdollisuuksia lupavaiheen näkökulmasta. Hankkeen loppuraportti ilmestyy alkuvuodesta 2017.

Análise de Sustentabilidade em Projetos de Instalações de Produção de Petróleo

A proposal for a global analysis of sustainability in projects related in oil facilities is presented. By considering economic, environmental and social aspects in the early stages of design, the suggested method is more comprehensive and can be used to complement the analysis commonly applied in the petroleum industry, such as: Study of Technical and Economic Feasibility; Environmental Impact Assessment and Risk Analysis. Several authors, associations, certification bodies and oil companies suggest different approaches to study sustainability in some specific activities (or industries). In this study, a checklist of significant sustainability aspects for the oil industry (surface facilities) was assembled. In addition, a matrix was developed to assess the sustainability items relevant to these projects. In this work, the checklist interacts with the matrix to perform a "Preliminary Analysis of Sustainability of the Enterprise" (APSE). This method allows the identification of aspects that contribute significantly to global sustainability. From this analysis, which includes economic, social and environmental aspects, is built a report that is used to analyze qualitatively and quantitatively the impact of the sustainability aspects of the project. In this analysis are identified items that strongly influence the economic, social or environmental aspects and evaluated alternatives that can increase the overall sustainability of the project. Finally, the alternatives that can be used to indicate the most sustainable option are identified. This method was applied in a project (design) of a small offshore platform. This case study shows how the APSE can contribute to the identification of sustainability initiatives for the enterprise. The results showed that relevant aspects can contribute decisively to global sustainability. Finally, it was observed that the proposed method can contribute to increased rates of sustainability, even after application of analysis commonly used in these projects

Water Demand and Allocation in the Mara River Basin, Kenya/Tanzania in the Face of Land Use Dynamics and Climate Variability

The Mara River Basin (MRB) is endowed with pristine biodiversity, socio-cultural heritage and natural resources. The purpose of my study is to develop and apply an integrated water resource allocation framework for the MRB based on the hydrological processes, water demand and economic factors. The basin was partitioned into twelve sub-basins and the rainfall runoff processes was modeled using the Soil and Water Assessment Tool (SWAT) after satisfactory Nash-Sutcliff efficiency of 0.68 for calibration and 0.43 for validation at Mara Mines station. The impact and uncertainty of climate change on the hydrology of the MRB was assessed using SWAT and three scenarios of statistically downscaled outputs from twenty Global Circulation Models. Results predicted the wet season getting more wet and the dry season getting drier, with a general increasing trend of annual rainfall through 2050. Three blocks of water demand (environmental, normal and flood) were estimated from consumptive water use by human, wildlife, livestock, tourism, irrigation and industry. Water demand projections suggest human consumption is expected to surpass irrigation as the highest water demand sector by 2030. Monthly volume of water was estimated in three blocks of current minimum reliability, reserve (>95%), normal (80–95%) and flood (40%) for more than 5 months in a year. The assessment of water price and marginal productivity showed that current water use hardly responds to a change in price or productivity of water. Finally, a water allocation model was developed and applied to investigate the optimum monthly allocation among sectors and sub-basins by maximizing the use value and hydrological reliability of water. Model results demonstrated that the status on reserve and normal volumes can be improved to ‘low’ or ‘moderate’ by updating the existing reliability to meet prevailing demand. Flow volumes and rates for four scenarios of reliability were presented. Results showed that the water allocation framework can be used as comprehensive tool in the management of MRB, and possibly be extended similar watersheds.
