Full textTot i sumar una extensió molt superior a la xarxa de carreteres, i malgrat conservar funcions d'interès per al conjunt de la societat i assumir-ne de noves, els camins no han merescut fins ara una atenció acadèmica o científica suficient. Una gestió integrada dels camins exigeix un coneixement aprofundit de les múltiples facetes que presenta l'objecte: tècnica o morfològica, jurídica i legal, funcional, i patrimonial. La gestió dels camins és al nostre país una assignatura pendent de l'ordenació del territori.
Aquesta tesi doctoral aborda la definició i la comprensió de l'objecte d'estudi en totes llurs dimensions, amb l'objectiu de definir un nou model de gestió dels camins en zones rurals. L'àmbit d'estudi específic són les comarques de muntanya del Pirineu català, si bé la recerca fa referència al conjunt de l'espai rural.
La recerca efectuada analitza la relació existent entre impactes ambientals i impactes sobre les activitats rurals, d'una banda, i morfologia, funcionalitat i ús del viari rural, de l'altra, i proposa un model de regulació dels camins (de l'ús i de les característiques tècniques) fonamentat en una classificació funcional de la xarxa i en la fragilitat ecològica del territori servit, al marge de les característiques tècniques o morfològiques dels vials. En aquest context ha tingut una gran significació l'estudi del tractament diferenciat que han de rebre les formes d'accés motoritzat (professional, de lleure...) i no motoritzat (a peu, bicicleta, cavall...) al medi natural. El model proposat dissenteix essencialment dels principis introduïts per la Llei 9/1995, de regulació de l'accés motoritzat al medi natural, que restringeix l'ús dels camins únicament en base a criteris morfològics.
Amb l'objectiu de validar el model proposat s'ha efectuat un estudi comparatiu dels models de gestió dels camins i l'accés al medi natural existents als parcs de muntanya del Pirineu català: Parc Nacional d'Aigüestortes i Estany de Sant Maurici, Parc Natural del Cadí-Moixeró i Parc Natural de la Zona Volcànica de la Garrotxa. De la mateixa manera s'ha fet una recerca comparada de diferents models internacionals: Anglaterra i Gal·les, Alemanya, França i Suïssa.
Without the existence of rights of way, access to the countryside would be impossible or, at least, only viable under very rough conditions. Certainly, rights of way constitute a vast network in rural areas that, even today, fulfil many important social and economic functions: communication within local communities, for farming, forestry, civil defense, natural heritage management, leisure and tourism... However, the urban and industrial nature of modern society has relegated rights of way to a marginal position, just as it has done with the space they serve: the countryside.
Rights of way make up a much greater share of the communications network than roads. Nevertheless, although they maintain functions of interest to society as a whole, and continue to assume new ones, they have not yet received sufficient academic or scientific attention. A comprehensive management of rights of way requires a deep knowledge of their many-sided nature: technical or morphological, juridical and legal, functional, and historical. Rights of way management is currently absent in land planning in our country.
This dissertation undertakes the definition of the object and the comprehension of all of its dimensions with the purpose of defining a new model of rights of way management in the countryside. The area of study includes the mountain counties of the Catalan Pyrenees, though the research refers to the rural space as a whole.
The research analyses the relationship that exists between the impacts on the environment and rural activities, on the one hand, and the morphology, function, and use rights of way, on the other. This leads on to the proposal of a model for the regulation of the use and technical features of rights of way, based on a functional classification of the network and the ecological vulnerability of the surrounding territory, regardless of the morphological or technical attributes of the rural roads or paths in question. In this context, the study of the separate treatment that should be given to access to the countryside in motorised vehicles (for work or leisure) and by other means (on foot, bicycle or horseback) has achieved great significance. Our model differs profoundly from the principles introduced by the Catalan 9/1995 Motorised Access to the Countryside Act, which introduces restrictions on the use of rights of way solely on the basis of morphological criteria.
The model proposed has been ratified, by undertaking a comparative study of rights of way management and access to the countryside schemes existing in the Catalan mountain parks: Aigüestortes i Estany de Sant Maurici National Park, Cadí-Moixeró Natural Park and Zona Volcànica de la Garrotxa Natural Park. Further research has similarly been undertaken on international access models: England and Wales, Germany, France and Switzerland.

Full textIn this dissertation new models of propagation path loss predictions are proposed by from techniques of optimization recent and measures of power levels for the urban and suburban areas of Natal, city of Brazilian northeast. These new proposed models are: (i) a statistical model that was implemented based in the addition of second-order statistics for the power and the altimetry of the relief in model of linear losses; (ii) a artificial neural networks model used the training of the algorithm backpropagation, in order to get the equation of propagation losses; (iii) a model based on the technique of the random walker, that considers the random of the absorption and the chaos of the environment and than its unknown parameters for the equation of propagation losses are determined through of a neural network. The digitalization of the relief for the urban and suburban areas of Natal were carried through of the development of specific computational programs and had been used available maps in the Statistics and Geography Brazilian Institute. The validations of the proposed propagation models had been carried through comparisons with measures and propagation classic models, and numerical good agreements were observed. These new considered models could be applied to any urban and suburban scenes with characteristic similar architectural to the city of Natal

Full textIndigenous peoples are increasingly facing threats resulting from a changing global environment. Given the unprecedented rates of ongoing Global Environmental Change, there is scholarly debate on whether these threats might also undermine the adaptive capacity of indigenous knowledge. Due to its strategic position bridging the natural and social sciences, ethnoecology is well-placed to examine to what extent indigenous knowledge is adaptive in the face of rapid environmental changes. This PhD thesis is the result of a three-year interdisciplinary study aiming to understand the relations between Global Environmental Change and the Local Environmental Knowledge held by a native society in Bolivian Amazonia: the Tsimane’ hunter-gatherers. Facing rapidly changing social-ecological conditions and with the scientific discourse on anthropogenic global change still largely inaccessible to this group, the Tsimane’ constitute a suitable case study for casting light on how local perceptions of Global Environmental Change are captured in the social memory of indigenous peoples. The main argumentative line of this work is that Global Environmental Change has direct expressions at the local scale, including changes related to climate, the ecosystem and the availability of natural resources. In its four central chapters, this dissertation empirically investigates: (a) the potential use of indigenous knowledge for complementing scientific models assessing climate change; (b) the interplay between local observations of climate change and the uptake of scientific information; (c) the limits of the adaptive capacity of Local Environmental Knowledge in a context of rapid change; and (d) the role of local perceptions of change as drivers of adaptation to ecological shocks. This research involved qualitative and quantitative data collection during 15 months of fieldwork in 23 villages of the Tsimane’ Territory. I used a number of methods common to ethnoecological research, including participant observation, focus groups and systematic data collection. I specifically conducted semi-structured interviews on environmental change perceptions (n = 300 adults), knowledge tests to assess individual levels of Local Environmental Knowledge (n = 99) and a randomised controlled trial (n = 442). Additional climate and ecological data were sourced to obtain scientific estimates of environmental changes in the study area. The results of this dissertation show that the Tsimane’ identify a wide array of local indicators of environmental change. Such indicators could help to fill gaps in instrumental records of Global Environmental Change. This thesis also shows the existence of a significant overlap between Tsimane’ indigenous knowledge and scientific climate change records, as well as the instrumental role that local perceptions play in sparking collective responses for adapting to change. However, findings from this work also illustrate how Global Environmental Change challenges the adaptive capacity of Local Environmental Knowledge by widening the temporal gap between the rates of change in the ecosystem and the rates of change in the knowledge held by indigenous societies. This thesis brings new insights to the theoretical discussion on the effectiveness of Local Environmental Knowledge in the context of rapid and unprecedented social-ecological changes. Results of this work stress the importance of devising strategic plans to support the resilience of indigenous knowledge in the face of ever encroaching environmental changes. This study also shows the importance of building upon Local Environmental Knowledge for informing and facilitating adaptive processes, particularly in areas inhabited by indigenous groups. Given these findings, I argue for an integration of indigenous peoples in global environmental policy fora, as well as for the recognition of their knowledge systems in scientific scholarship.

Full textEn esta tesis, datos diarios de temperaturas máximas y mínimas y precipitación de 12 estaciones guineanas han sido sometidos a controles de calidad utilizando las rutinas RClimdex-ExtraQC. Estas rutinas contienen herramientas para una serie temporal única. Los valores identificados como potencialmente erróneos han sido examinados y mediante decisión subjetiva, han sido validados, corregidos o eliminados. Estos datos libres de cualquier tipo de registro sospechoso han sido homogeneizados utilizando el archivo de salida HOMER de datos mensuales. Índices elegidos de ETCCDI y ET-CRSCI se han calculado para las temperaturas y precipitaciones anuales y estacionales utilizando ET-CRSCI del paquete R ClimPact. Además, promedios anuales de Tx, Tn y precipitación nacional y ocho índices de extremos han sido usados para detectar teleconexiones entre los índices climáticos y el índice SOI. Un análisis de tendencias no paramétrica se ha realizado sobre tres períodos superpuestos que empiezan en 1941, 1961 y 1971, y terminan todos en 2010. Los resultados indican diversos patrones espaciales coherentes con el calentamiento, significativos, identificados tanto en los índices de extremos de Tx como de Tn para todos los periodos y estaciones. Los índices basados en datos de precipitación diaria mostraron patrones menos coherentes pero, en general, existen patrones de sequía significativos en la mayoría de los índices relacionados con la precipitación diaria para los períodos 1941-2010 i 1961-2010, mientras que para el período 1971-2010 el análisis sugiere cambios no significativos hacia condiciones más húmedas. En general, no se han producido cambios espacialmente coherentes con eventos extremos de precipitación para el conjunto de Guinea y el período de estudio, ya que estos, se han producido a escala local. Hay indicios de que las condiciones más húmedas están asociadas con La Niña. Las precipitaciones durante el periodo 1971-2010 han sido entre un 13.6% y un 27.75% menores que durante el período 1941-1970.
In this thesis, Guinea's 12 weather stations daily minimum and daily maximum temperatures and daily precipitation data have been carefully quality controlled using the RClimdex-ExtraQC routines. These routines contain suitable tools to quality control single time series. The values identified as potentially erroneous have been carefully scrutinized and a subjective decision has been made to validate, correct or set them to missing. The resulted dataset free of any kind of suspicious data record has been homogenized using HOMER monthly output file. Chosen indices from ETCCDI and ET-CRSCI indices have been calculated using ET-CRSCI ClimPact R package. Annual and seasonal temperatures and precipitations indices have also been computed. Additionally, eight nationwide averaged climate extremes indices, the nationwide averaged annual Tx mean and Tn mean and total precipitation indices have been use to detect teleconnection between climate indices and SOI indices. A nonparametric trend analysis is then performed for three overlapping periods, with different starting years 1941, 1961 and 1971 but all ending the same 2010 year. The result suggested that coherent spatial patterns of significant warming changes have emerged from both Tx and Tn related extremes indices for all periods and season. Indices based on daily precipitation data showed more mixed patterns of change but, in general, significant drying patterns have been seen in most of the 1941-2010 and 1961-2010 periods' daily precipitation related indices while over the period 1971-2010 analyses suggested non-significant changes towards wetter conditions. Overall, there have been no spatially coherent changes in extreme rainfall events across Guinea for the study period, but changes in extreme precipitation events have occurred on local scales. There are signs that wetter conditions are associated with the La Niña years. Rainfall during the 1971-2010 is on average some 13.6 % to 27.75 % lower than during the period 1941–1970.

O surgimento da Telefonia Celular, a partir dos anos 1990, e a constru??o fren?tica de torres nas cidades assustou a popula??o, levou a comunidade cient?fica mundial e os ?rg?os de controle ambiental a dar maior aten??o ?s ondas eletromagn?ticas n?o ionizantes. Um estado pobre como o Rio Grande do Norte evoluiu a quantidade de celulares em opera??o de 340 mil no ano 2002 para 4,6 milh?es em 2014. No RN a quantidade de linhas celulares supera a pr?pria popula??o, com uma densidade de 128,98 acessos para cada 100 habitantes. Natal, a capital do RN, com 850 mil habitantes, j? possui 882 Esta??es R?dio Base dos Sistemas celulares em 167,26 km2 de ?rea urbana. O objetivo do presente trabalho ? fazer um diagn?stico sobre a exposi??o ? radia??o eletromagn?tica n?o ionizante em toda ?rea urbana da Cidade. A metodologia usada levou em conta medi??es de intensidade das radia??es feitas em 160 diferentes pontos da cidade. As medi??es foram feitas na faixa de 88MHz a 2.400 MHz. Os servi?os de telecomunica??es avaliados na pesquisa foram: TV (Broadcasting), R?dio FM (Broadcasting), Sistemas Celulares e WLAN (IEEE 802.11bg).Foram considerados para compara??o os limites de exposi??o do ICNIRP (InternationalCommission on Non IonizationProtection), par?metros: ?Intensidade de Campo El?trico? e ?Raz?o de Exposi??o? (ER). Resultados: de acordo com as medi??es realizadas, 48.48 % da exposi??o eletromagn?tica outdoor na cidade do Natal decorre da radia??o emitida pelos transmissores de TV. Da mesma forma, constatou-se que, em 77,2 % dos pontos pesquisados, a intensidade do campo el?trico gerada pelas TVs supera todos os demais servi?os de telecomunica??es, inclusive a Telefonia Celular. A Taxa de Exposi??o (ER) m?dia de Radia??o N?o Ionizante verificada para a faixa de frequ?ncia pesquisada foi de 4,43. 10 -3, enquanto o valor m?ximo foi de 7,67. 10-2. Foi desenvolvido modelo para estimativa do Campo El?trico gerado pelos transmissores das TVs em qualquer ponto da cidade. Utilizouse a T?cnica Estat?stica de Regress?o Multivariada, a partir das 160 amostras. As equa??es finais obtidas permitem as estimativas com grau de precis?o R2 superior a 0,9, p<0,1. Constatou-se que o expoente de atenua??o para propaga??o de RF na cidade varia entre 2,8 e 3,8. A exposi??o eletromagn?tica ? RNI em ambientes outdoor em Natal est? em n?veis abaixo dos limites de seguran?a definidos pelo ICNIRP e ANATEL. Os servi?os que mais contribuem para RNI em Natal s?o: 1-TV, 2-Sistema Celular e 3-R?dios FMs.
The electromagnetic waves used in the telecommunication systems until the 1980?s were considered by the governments environmental control organs as apparently ?clean? forms of energy, whose effects weren?t considered any harmful to people?s health. The development of the mobile cellular telecommunication, beginning in the 1990?s, and the frenetic construction of antennas in the cities? urban areas scared the population in general and turned the attention of the world?s scientific community to the theme. In a poor Brazilian State, such as Rio Grande do Norte ? RN (GDP:R$ 51,4 billion in 2013) , the amount of cellular phones in operation went from 340.000 in 2002 to 4.6 million phones in 2014. In RN the number of cellular lines overcomes its own population, with a density of 128.98 accesses for each 100 inhabitants. Natal, the capital city of the State, with 850.000 inhabitants, already has 885 radio base stations of the cellular systems in 167.26 km? of urban area. The data is from ANATEL (august 2015). The objective of this work is to make a diagnosis about the actual situation of the emission of non-ionizing electromagnetic radiation in all urban area of the city of Natal. The methodology used took into account measurements of the intensity of the radiation taken in 160 different sites throughout the city. This radiation was measured in the range of 88MHz to 2.400 MHz. The collected data was compared to the limits of exposure of the ICNIRP (International Commission on Non Ionization Protection). The ICNIRP parameters used as reference were: ?intensity of electric field? and ?exposure ratio?. The telecommunication services researched were: TV broadcasting, FM radio broadcasting, cellular systems and WLAN (IEE 802.11bg). The obtained results allowed the drawing of a map comparing the data between the measured values and the limits of exposure to RNI defined by ICNIRP and ANATEL. The evaluation criteria used was the parameters Intensity of Electric Field and Exposure Ratio (ER). Results: according to the measurements taken, 48.48% of the outdoor electromagnetic exposure in the municipality of Natal are originated from TV transmitters. Similarly, in 77.2% of the researched locations, the intensity of the electric field originated from TVs overcomes all the rest of the wireless telecommunication services, including the cellular system. Based on the information that the radiation emitted by the TV transmitters is the most relevant in the city, a model to estimate the intensity of the electric field resulting from this service in any point in town was developed. This model was developed based on multivariate regression techniques. The final equations obtained allowed the estimative of the electric field with a level of precision R2> 0,9 and p<0,1. It was found that the exponent RF propagation attenuation in Natal varies between 2.6 and 2.8.The average Exposure Rate (ER) to NIR observed in the researched frequency rate was of 4.43.10-3, while the maximum value was of 7.67. 10- Conclusions: The results of the study demonstrated that the levels of electromagnetic exposure to NIR in outdoor environments in the city of Natal are lower than the security limits set by ICNIRP and ANATEL. The services that contribute most to NIR in Natal are 1-TV, 2- Cellular System and 3-FM Radios.
