Повний текст джерелаFacing the total and social changes which unsettle the living conditions of the stockbreeders of the pastoral zone of the north Niger, what contribution can they brought for a lasting management of plant resources? It is in this question that this thesis tries to answer in the context of the plain of Eghazer, true regulating lung for the pastoral animal husbandry of Niger, located north of this pastoral zone of the country. Every year, from July of many transhumants from the south rush in the pastoral zone of Eghazer joining so the local stockbreeders. This summer called migration " salt Remedy " aims at the working of the seasonal pasture rich in mineral salts very appreciated by the pastors. These rich and various pastoral resources, even if they are very variable according to the years, make of Eghazer, one of the last zones of big seasonal concentration of the stockbreeders. Locally, the pressure on lands and resources becomes more and more strong and the durability of the system parried compromised. Search was conducted by calling methods of cartography, of study of vegetation, quantitative and qualitative inquiries most often participative. This job showed that the pastors developed group of knowledge on the plant resources allowing them to resist the difficult conditions of the practice of the pastoralisme in arid middle. These local knowledges are also translated in a detailed description of the middle leaning on topographical criteria, géomorphologiques and functional, and that the evaluation in quality terms of pasture depends on factors of variable importance according to seasons. It emerges moreover that these traditional knowledges can be combined with scientific knowledge in the development of card of landscapes, main element of joint management. Finally, the study of pasture across both (scientific and vernacular) evaluations allowed to know the state of pastoral resource, notably of vegetation. She also highlighted the priority zones of interventions in the pastoral zone of Eghazer. The crossing of these vernacular knowledges of the pastors with scientific knowledge can be a trump favourable to the installation of a device of joint management of the pasture of Eghazer

The current use of health facilities by pastoral people reveals specific choices and strategies that are analyzed here with the tools of Health Geography. The study shows the assets but also the disconnections between the pastoral space, the health supply space and the health demand space, with the case-studies among arabic and dazagara communities in western Chad. It suggests practical solutions to encourage a health policy that takes more nomadic people needs into account

Повний текст джерелаIn the face of unfavorable rearing conditions, the State sees in the creation of pastoral areas an opportunity to inject a new dynamic into livestock farming by improving production techniques. It is in this context that the pastoral zone of Nouhao was created and there were officially installed Fulani breeders. This installation was preceded by several achievements in order to ensure in a sustainable way, a satisfactory availability and at any time of the year, food resources, water, as well as a sanitary supervision for the animals of the said zone. Despite the many achievements that have brought benefits to pastoralists, they have retained their traditional system of pastoral resource exploitation.The study aims to identify the motivations of the actors in the persistence of the practice of mobility outside the pastoral zone. The survey carried out among stakeholders in different fields of activity has made it possible to provide answers to a specific question of mobility that is the transhumance of pastoralists and Fulani herdsmen in the pastoral zone of Nouhao

Повний текст джерелаWind scatterometers (WSC) are radar sensors that operate at coarse spatial resolution (50 km) and high temporal resolution (one acquisition every 3-4 days approximately). They are well suited to land surface monitoring at global and regional scales. Due to their high sensitivity to strong biomass and soil moisture seasonal variations, they show good potential for the monitoring of semi-arid regions such as the Sahel in West Africa. Previous studies conducted over the relatively homogeneous Sahelian pastoral areas have led to the output of herbaceous mass maps derived from WSC data. In order to extend those studies to the entire Sahelian belt, the objective of this thesis is to investigate the potential of scatterometers for the monitoring of agro-pastoral zones, which are characterized by greater spatial heterogeneity at the scale of a resolution cell. The study area, where numerous in situ measurements have been carried out during the 1992 2000 period, is located in the Fakara region, Niger. First, the influence of the study area’s spatial heterogeneity is investigated by comparison with ERS synthetic aperture radar data, whose spatial resolution is higher (around 20 m). Then, a quantitative analysis is carried out by coupling a Sahelian ecosystem process model, which describes the evolution of the observed scene, with a backscattering model that simulates the signal as a radar sensor would measure it. Results show that the influence of vegetation on the signal is negligible due to low vegetation cover in agro-pastoral areas. This allows the retrieval of surface soil moisture from WSC data alone over such areas

Повний текст джерелаMacrosegregation is a source of serious problems in castings, but it can be a useful tool in metallurgical refining processes such as those employed in the production of high-purity silicon. It is often a result of convective liquid flow either at planar solidification or when a mushy zone is present, while diffusive solute transport is effective at controlled directional solidification with planar interfaces. Ingot solidification modeling at macroscopic scale is currently divided in models assuming a mushy zone is always present and planar interfaceassuming models, thus requiring prior knowledge of interface morphology. A mathematical model for macrosegregation resulting from diffusion and convection during solidification with planar interface or mushy zone was presented and implemented. Diffusive transport was evaluated numerically, revealing a transition from planar to mushy-zone solidification conforming to classical stability criterions, with an initial refined zone that grew even after a mushy zone developed and the inefficacy of macrodiffusion-induced macrosegregation at higher growth velocities shown. Convection showed stabilizing effect for planar solid-liquid interface by reducing the solute-undercooled layer and increased macrosegregation, with a tendency towards Scheil model. Silicon experiments publicly available were compared with the present model, confirming the experimentally-observed stabilizing effect and proving the key role of diffusion at macrosegregation formation on these systems. The model was evaluated with experiments made in a Bridgman-type furnace with an Al-1% Cu alloy with increasing growth velocities to study interface stability and macrosegregation with or without liquid stirring. Results indicate a planar growth region followed by a cellular interface one after the second velocity change, as identified by metallographical testing. Critical growth velocities for classical criterions were estimated after the experiments and were smaller than the evaluated ones.

Повний текст джерелаThis research analizes the social practice of the Northeast’s Pastoral Land Commission (CPT NE 2), a lay organization of the Catholic Church, in the Northeast region. Serving rural workers and landless people, in the struggle for agrarian reform, the organization operates in the septentrional part of the sugar-cane zone of the state of Pernambuco (Brazil). The analysis covers the period from 1988, the year of its foundation, and early 2000s, when its participation in land conflicts and occupancy movements decreases. The central issue is intended to question the actions of CPT in rural areas to understand whether it is an unprecedented form of social engagement or, as their own actors state, "a new way of being Church." In order to do so, we analyze, at first, from the standpoint of former Catholic organizations, created in the early 1960s, in the context of Rural Catholic Action. Comparing between JAC, MEB, SORPE, ACR, MER, on one side, and PR NE 2 and CPT, on another, which is the portion of continuities and disruptions? Then, the organization is discussed in terms of its engagement in the struggle for the agrarian reform, the social movements it participates and its relationship with other social actors: MST, STRs, FETAPE, the political sphere and public authorities, to identify its performance and define its originality. Finally, its practice is examined from the social environment, the socio-religious matrixes from which its actors and mediators who transmit the social memory of the Church in the region. At last, the research also aims to define how and to what extent the performance and the actors of CPT NE 2 result from the mobilization strategies of the New Social Movements (NMS) that operate in Latin America and, especially in Brazil, as of the 1980s
Esta pesquisa procura analisar a prática social da Comissão Pastoral da Terra Nordeste 2 (CPT NE 2), uma organização leiga da Igreja católica, na região Nordeste. A serviço dos trabalhadores rurais e sem terra, na luta pela reforma agrária, a organização atua na parte setentrional da zona canavieira do Estado de Pernambuco (Brasil). A análise abrange o período compreendido entre 1988, ano de sua fundação, e o início dos anos 2000, momento em que a sua participação nos conflitos de terra e nos movimentos de ocupação diminui. A problemática principal visa a interrogar as ações da CPT nomeio rural a fim de compreender se ela constitui uma forma inédita de engajamento social ou, segundo afirmam os seus próprios atores, “uma nova maneira de ser Igreja”. Para tanto, nós a analisamos, num primeiro momento, do ponto de vista das organizações católicas anteriores, nascidas no início dos anos 1960, no contexto da Ação Católica Rural. Entre, de um lado, JAC, MEB, SORPE, ACR, MER e, de outro, PR NE 2 e CPT, qual a parcela de continuidades e de rupturas ? Emseguida, a organização é abordada do ponto de vista do seu engajamento na luta pela reforma agrária, das mobilizações sociais das quais ela participa e da sua relação com os outros atores sociais: MST, STRs, FETAPE, esfera política e autoridades públicas, a fim de identificar as suas formas de atuação e de definir a sua originalidade. Em último lugar, a sua prática é analisada a partir do meio social, das matrizes socio-religiosas de onde provêm os seus atores e dos mediadores que transmitem a memória social da Igreja na região. Por fim, a pesquisa visa também a definir de que forma e até que ponto as formas de atuação e os atores da CPT NE 2 resultam das estratégias de mobilização dos Novos Movimentos Sociais (NMS) que atuam na América Latina e, especialmente no Brasil, a partir dos anos 1980

Повний текст джерелаThe decline of agriculture has hastened the invasion of small shrubs in marginal areas, lowering the value of forage and of biodiversity. European environmental policies have then encouraged farmers to preserve biodiversity and to use pastoral practices allowing the management of inherited value areas, but current recommendations are inadequate for practical use. With this aim, the objective of my PhD was to design a model of the interactions between the eating habits of sheep and the population dynamics of invading shrub species (Cytisus scoparius). To link these processes up, my model is grounded on: the creation of demographical categories specified by their eating habits, the demographical spatialization determining the accessibility of the resource, the influence of herbaceous resource upon eating habits. The demographical data stemmed from experiments carried out on broom moors over a sheep farm, as well as the knowledge of eating habits and of pastoral practices. My model shows the importance of spatialization in the demographical strategy, the diversity of impacts of grazing according to consummated organs, and the role of grazing plans on population dynamics. This PhD underlines the interest of pluridisciplinary reasoning between ecology and biotechnical sciences to answer the aim of controlling shrub encroachment by grazing

Повний текст джерелаIn the chad basin, the spectacular expansion of transplanted sorghum at the end of the rainy season has deeply modified land use patterns and landscape structures. Simultaneously, mutations occurred in agrarian systems and land management have led to various development perspectives, for sedentary people as much as for transhumant populations. Actually, the multiple uses of space by different social groups produces the fitting of various spaces together, which means in fact the meeting and the overlay of both agricultural and pastoral spaces. In the chad Arabian context, the absence of conflict is explained by the use of crops residuals by droves. But this situation can evolve from the emergence of landownership market

La confrontation avec les données palynologiques, archéologiques et historiques dans le cadre de Programmes Collectifs de Recherches confirme la validité de la démarche pédoanthracologique et permet d'affiner la connaissance des évolutions de la végétation depuis 6000 ans. A une autre échelle de temps, la fiabilité des résultats est mise en avant par la comparaison des données anthracologiques avec les sources historiques de la Réformation du XVIIe siècle.

Повний текст джерелаThe aim of this thesis is to demonstrate the existence of a link between vegetation dynamics and agro-sylvo-pastoral activities in Pyrenees since Neolithic. Pedoanthracology uses soil-charcoals to reconstruct palaeovegetation landscapes. This study focused on mountain intermediary areas since they present remnants of charcoal kilns and agro-pastoral practices. For the first time pedoanthracology was used to study Pyrenees, more precisely basque mountain (Atlantic Pyrenees), Pays de Sault (Ariège) and Luchonnais (Haute-Garonne). This method was adapted to Cerdagne mountain (Eastern Pyrenees) in a geoarchaeological context. These data were in agreement with palynological, archaeological and historical results from Research Programs. This leads to a deeper understanding of vegetation dynamics since 6000 years and confirms our pedoanthracological approach relevance. Comparison of anthracological and seventeenth century historical data shows reliability of our charcoal results. Agricultural terraces study required development of a specific charcoal collecting process. Charcoal studies provide a new means to chronologically associate palaeovegetations to terraces constructions since at least Bronze Age

A presente pesquisa investiga a influência da Teologia da Libertação e das experiências vividas nas Comunidades Eclesiais de Base por conhecidos atores sociais da Zona Norte de São Leopoldo, entre eles, o Pe. Orestes Stragliotto, fonte principal da pesquisa em razão dos escritos deixados por ele e de entrevistas com alguns atores envolvidos nas mobilizações, os quais permeiam a análise acerca dos objetivos e hipóteses levantadas. Poucos discordam de que a Teologia da Libertação teve importância significativa dentro – e fora – da estrutura católica na história recente do Brasil. No entanto, estudos de casos de ações efetivas resultantes das práticas teológicas da libertação não são encontrados em profusão na Ciência Sociais. Esta pesquisa apresenta alguns resultados práticos de um estudo de caso da Teologia da Libertação a partir da práxis social do Pe. Orestes João Stragliotto e de atores sociais envolvidos pelo método sugerido pela Teologia da Libertação, qual seja, Ver, Julgar e Agir. Como resultado, vê-se que esta prática social resultou na formação de Movimentos Sociais e mobilizações populares na Zona Norte de São Leopoldo. Percebe-se que ela se deu nas décadas de 1980 e 1990 nas Comunidades Eclesiais de Base da Paróquia Santo Inácio, que influenciaram no modo de compreender a relação entre Igreja, política e vida, uma vez que estas práticas transformaram a realidade local e a vivacidade destes atores na institucionalidade política da cidade.
This thesis seeks to investigate the influence of Theology of Liberation and experiences of life that took place in some Basic Ecclesial Communities by social actors in the northern region of Sao Leopoldo city, including Fr Orestes Joao Stragliotto, who is our major source for the research conducted due to his writings and interviews from some social actors that participated in social mobilizations. These writings and interviews permeate our analysis around our objectives and hypothesis raised. Few people would disagree that Theology of Liberation has been important in – and outside – the Catholic structure in the recent history of Brazil. However, we do not find many case studies in the Social Sciences regarding effective actions as results from theological liberation practices. This research presents some practical results of a case study of Theology of Liberation from the social praxis of Fr Orestes Joao Stragliotto and of social actors by means of the method suggested in this theology, that is, See, Judge and Act. As a result, we see that the social practice has resulted the formation of social movements and popular mobilizations in the northern region of Sao Leopoldo. We also see that this practice took place in the 1980s and 1990s in the Parish Santo Inacio’s Basic Ecclesial Communities, which has affected the way people understood the relationship between the church, politics and life, once these practices have changed the local reality of the social actor and their vividness in the political institutionality.

Повний текст джерелаLa presente investigación versa sobre la relación existente entre la apropiación conflictiva de espacios naturales en ciudades industriales y las representaciones espaciales del progreso y la naturaleza. La representación espacial es el objeto de estudio de esta tesis y es definido como un conglomerado de relaciones presentes y pasadas que toman cuerpo efectivo en la ciudad pero que, de manera casi siempre inadvertida, se sostiene por discursos, metáforas, sentidos comunes y, sobre de todo, una movilización de recursos de poder. En este sentido, las representaciones espaciales son una yuxtaposición, como palimpsesto, de historias y relaciones, encarnadas en el territorio y que, de diferentes formas, regulan la conducta y normalizan ciertas realidades sociales. Esto no tendría mayor problema si todas las relaciones tuvieran las mismas posibilidades de ser representadas en el espacio. Mientras que los espacios de producción y consumo están sobrerrepresentados en la ciudad industrial, los espacios naturales son sistemáticamente eliminados ya sea para convertir el espacio en mercantil o bien, para producir un nuevo espacio natural, pero dentro de los circuitos comerciales. La hipótesis de esta investigación es que la sobrerrepresentación de la idea de progreso hace pasar por inexorable la necesidad de espacios productivos, mientras que la infrarrepresentación de los espacios naturales sostiene la falsa creencia de su irrelevancia. De manera que, aunque existan métodos controvertidos, incluso ilegales o coercitivos, para que manos privadas se apropien de espacios naturales públicos, el cuerpo de la ciudad, con esta sobrerrepresentación de espacios productivos, facilita este despojo. Esta investigación se apoya en un caso de estudio en el que precisamente un estadio de futbol soccer privado se construyó sobre un antiguo espacio natural público en la Zona Metropolitana de Monterrey. A través de entrevistas, análisis de documentación y observación participante, siguiendo la metodología de la Teoría Actor-Red, esta tesis analiza la relación entre tres representaciones espaciales clave del caso y su desenlace.
A presente investigação trata da relação entre a apropriação conflitiva de espaços naturais em cidades industriais e as representações espaciais do progresso e da natureza. A representação espacial é o objecto de estudo da presente tese e é definida como um conglomerado de relações passadas e presentes tomando corpo eficaz na cidade, mas de modo quase sempre despercebida sustentada por discursos, metáforas, o senso comum e, sobre tudo, uma mobilização de recursos de poder. Neste sentido, as representações espaciais são uma justaposição, como um palimpsesto, de histórias e relações incorporadas no território que, de maneiras diferentes, regulam o comportamento e normalizam certas realidades sociais. Isso não seria um problema se todas as relações tivessem as mesmas possibilidades de serem representadas no espaço. Enquanto as áreas de produção e consumo estão sobre-representados na cidade industrial, áreas naturais são sistematicamente apagadas para se converter num espaço comercial ou para produzir um novo espaço natural, mas dentro dos circuitos comerciais. A hipótese desta pesquisa é que a sobre-representação da ideia de progresso inexorável personifica a necessidade de espaços produtivos, enquanto a sub-representação de áreas naturais detém a falsa crença da sua irrelevância. Assim, embora existam métodos controversos, incluindo coação, para mãos privadas se apropriarem das áreas naturais públicas, o corpo da cidade, como uma super-representação de espaços produtivos, facilita esta apropriação. Esta pesquisa é baseada em um estudo de caso em que precisamente um estádio de futebol privado foi construído em um antigo espaço natural público na área metropolitana de Monterrey. Por meio de entrevistas, análise documental e observação participante, seguindo a metodologia da Teoria Ator-Rede, esta tese analisa a relação entre três representações espaciais-chave do caso e seu desfecho.
The present investigation deals with the relationship between the conflictive appropriation of natural spaces in industrial cities and the spatial representations of progress and nature. Spatial representation is the object of study of this thesis and is defined as a conglomeration of present and past relationships that take effective body in the city but that, almost always unnoticed, is sustained by discourses, metaphors, common senses and, above of everything, a mobilization of resources of power. In this sense, spatial representations are a juxtaposition, like palimpsest, of histories and relationships, embodied in the territory and that, in different ways, regulate behavior and normalize certain social realities. This would not be a problem if all the relations had the same possibilities of being represented in space. While the spaces of production and consumption are overrepresented in the industrial city, the natural spaces are systematically eliminated either to convert the space into a mercantile or to produce a new natural space, but within commercial circuits. The hypothesis of this research is that the overrepresentation of the idea of progress passes through the inexorable necessity of productive spaces, while the underrepresentation of natural spaces sustains the false belief of its irrelevance. So, although there are controversial methods, even illegal or coercive, for private hands to appropriate public natural spaces, the body of the city, with this overrepresentation of productive spaces, facilitates this dispossession. This research is based on a case study in which precisely a private soccer stadium was built on an old public natural space in the Metropolitan Area of Monterrey. Through interviews, documentation analysis and participant observation, following the methodology of the Actor-Network Theory, this thesis analyzes the relationship between three key spatial representations of the case and its outcome.

Al mismo tiempo, la disminución de las precipitaciones ocurridas a partir del año 2008 repercutió negativamente en la producción de forraje. Esta menor oferta forrajera se sumó al aumento de carga, poniendo en riesgo la continuidad de las empresas ganaderas, principalmente las dedicadas a la actividad cría, que tienen como característica poco margen para ajustar cargas. Con el objetivo de atenuar los efectos que producen las variaciones de las precipitaciones sobre los resultados físicos y económicos en un sistema de cría, en el presente trabajo se describe el seguimiento de una unidad de producción ganadera de cría (no experimental) donde se fueron aplicando, con el transcurrir de los años, distintas propuestas tecnológicas. Las propuestas, denominadas tratamientos, fueron las siguientes: a) dos tipos de pastoreos rotativos con distintos niveles de intensificación, S1 rotativo de 4 lotes y S2 rotativo de 25 lotes, b) tres combinaciones de recursos forrajeros T1 campo natural 100% , T2 70% campo natural + 30% pasturas implantadas , T3 70% campo natural + 24% pasturas implantadas + 6% silaje de planta entera de sorgo o maíz. Todos los tratamientos fueron evaluados en dos series de años, los denominados años húmedos (con alrededor de 800 mm) y los denominados años secos (precipitaciones próximos a los 600 mm). Se observó que los tratamientos que resultaron más afectados, en la serie de años secos, fueron aquellos que aplicaron menos tecnología (S1T1 y S1T2), mientras que el tratamiento S2T2 presentó valores intermedios y S2T3 los mejores resultados. La combinación S2T3 fue la que presentó menor variabilidad porcentual de sus resultados físicos entre años secos y húmedos. Se concluye que es posible sostener los niveles de producción de carne en sistemas de cría en años de menores precipitaciones, con la aplicación de un paquete tecnológico que combine sistema de pastoreo controlado con uso de pasturas cultivadas y confección de reservas forrajeras. Sin embargo, aunque se sostenga la producción física, en años secos se afecta negativamente el resultado económico.

Повний текст джерелаLos sistemas de cría bovina de la región Chaqueña semiárida se caracterizan por su baja productividad. En la provincia de Santiago del Estero la recría de vaquillonas de reposición es la categoría que presenta mayores dificultades. Debido a sus altos requerimientos nutricionales y a la escases de recursos forrajeros esta categoría presenta lento desarrollo y baja eficiencia reproductiva. El objetivo del presente trabajo fue generar criterios de uso de los recursos forrajeros y la suplementación estratégica, para un sistema de recría de vaquillonas en el Chaco Semiárido que nos permita llegar a un peso mínimo promedio de 290 kilogramos y una edad de 24 meses al primer servicio. Se implementó un sistema silvopastoril, sobre una estructura leñosa de especies nativas (Prosopis nigra, Schinopsis lorentzii, Ziziphus mistol, Celtis chichape) con una densidad de 301arboles/ha. El estrato herbáceo estuvo compuesto por gramíneas nativas (Tríchloris Crinita, T. Pluriflora, Setaria leiantha,) y pasturas implantadas (Panicum maximum cv. Gatton Panic, Cenchrus ciliaris cv. Biloela). Se implementó un sistema de pastoreo rotativo por decisión y una suplementación estratégica con semilla de algodón (SA) al 0,6% del peso vivo (PV) durante 100 días teniendo en cuenta, la condición corporal (CC) y estado de la pastura. Se obtuvieron Ganancias de Peso Diario (GPD) de 0,413 Kg promedio, se observó que no hubo pérdidas de peso ni de CC, esto coincidió con la evolución del PV que fue de 97 kg±13 a 250 kg±24, (01/06/11 al 06/06/12) produciendo 95,8 kg PV/ha. La producción de materia seca (MS) se estimo mediante el método del BOTANAL y siguió una curva sigmoidea normal coincidiendo los momentos de máxima producción con la distribución de las lluvias. De los resultados obtenidos se infiere que con un manejo integral de los componentes del sistema propuesto se puede recriar una hembra de reposición con 24 meses y con un peso óptimo, conservando el bosque nativo y utilizando como única fuente de suplementación SA insumo utilizado frecuentemente en los sistemas ganaderos de la región.
