Loubaud, Eric. « Enjeux géopolitiques des risques et des catastrophes d'origine naturelle : cas des inondations affectant la ville de Trinidad (Beni, Bolivie) ». La Rochelle, 2009. http://www.theses.fr/2009LAROF030.
Texte intégralSufriendo regularmente de inundaciones, la ciudad de Trinidad (ubicada en el corazón de la llanura inundable de Mojos, en la que se inundan entre 100000 y 150000 km2 cada ano entre los meses de enero a mayo) deja aparecer zonas de riesgo en sus márgenes. Estudiarlas nos permitirá poner de relieve comportamientos y estrategias que corresponden a cada actor del riesgo de inundación. Además, en un contexto político boliviano inestable donde se observa una importante fractura entre un occidente andino apoyando al presidente E. Morales y un oriente de las tierras bajas (donde se localiza Trinidad) oponiéndose abiertamente al gobierno nacional, una crisis de grande amplitud en esta última región aparece como un momento estratégico para tratar de ganar simpatía y por consecuencia, territorio político para el presidente de la República. En resumidas cuentas, además de los cuestionamientos sobre apuestas geopolíticas que representan el riesgo de inundación y la catástrofe en Trinidad y en el Beni, esta tesis nos permite también preguntarnos sobre un contexto político demasiado resumido a los enfrentamientos que oponen una Santa Cruz rica y un gobierno de cambios
Confronted with regular inundations (the city is located in the center of the floodplain of the “Mojos”: 100. 000 to 150. 000 km² flooded nearly each year between january and may), Trinidad is forced to notice that risky gaps appear around its margins. Examine them will permit to set in the foreground behaviours, strategies corresponding to each actor of the risk. In addition, in an unstable bolivian political context where an important fracture between an “andin occident” largely in favour of the president E. Morales, and a lowland orient (where Trinidad is located) in a marked opposition with the national government is watchable, an important crisis in this land becomes a strategic period to try to earn sympathy, and so territory for the president of the Republic. In sum, besides questionings about the geopolitical stakes representing the inundation’s risk and the disaster in Trinidad and in Beni, this thesis makes us query on a political context often summed up to confrontations between a wealthy Santa Cruz and a government for changes

Texte intégralOur human society is at present becoming increasingly concerned with issues of pollution and with the impact of this pollution on environment and human health. Among those health- endangering substances are heavy metals, including mercury. The latter, which is notably present in the Amazon environment, accumulates in the aquatic food chain and becomes a hazard to people whose staple diet is fish. In the Bolivian Amazon the populations of fifteen villages on the Río Beni riverbanks are thus exposed to it. However, as significant differences in contamination levels can be observed from one village to the next, the factors causing these discrepancies along the river need to be studied more carefully. This study shows that contamination differences vary with differences in resource management (such as farming, fishing, hunting, fruit gathering, logging, employment work, trading,. . . ) which result from a socio-spatial system, which is examined on different scales. The pathogenic system of mercury contamination along the Río Beni includes the geographical situation, the types of community organization, the history of these villages, the types of resource management, the social links with external actors, the coherence of the territories in which these villages are located. Consequently, mercury contamination is not inevitable. This geographical approach helps to identify unsuspected factors of mercury contamination that can serve to lay the foundations for planning and development policies along the Río Beni. With adjustments made to the context and with the capital condition that the research work is resolutely interdisciplinary, a geographical approach of long-term exposure to low doses of pollutants could shed a new light on complex systems leading to the contrasted exposure of populations

Texte intégralDesde 1999, el Deutsches Archäologisches Institut y la Unidad Nacional de Arqueología de Bolivia dirigen un proyecto arqueológico de manera conjunta para efectuar investigaciones en montículos habitacionales del sureste de los Llanos de Mojos (departamento del Beni). En este trabajo se presentan datos obtenidos de excavaciones en el sitio de Loma Salvatierra, con énfasis en el uso espacial dentro del sitio y el hallazgo de una tumba excepcionalmente "rica". Estos datos contribuyen a la discusión general sobre la existencia de sociedades complejas en la Amazonía prehispánica.

Texte intégralThe witches’ broom disease (Crinipellis perniciosa) is a fungal infection which only affects the meristematic plant tissues of the cocoa tree. To date it has been restricted to the Latin American continent. The aim of this work was to examine scientifically the measures undertaken in the Alto Beni region in the humid tropical lowlands of Bolivia, to curb the witches’ broom disease (Crinipellis perniciosa) by phytosanitary pruning measures and by the use of various tolerant clones From 1994 to 97, the cocoa clones ICS 1, ICS 6, ICS 8, ICS 95 and TSH 565 were also studied under field conditions at the Sapecho location for witches’ broom tolerance and yield. In addition, various pruning frequencies were examined for their efficiency with regard to the yields of the clones and the effects on witches’ broom infection The results show a connection between rainfall levels and the formation of basidiocarps on the witches’ broom. However, over the whole of the investigation period, no causal connection was found between the intensity of basidiocarp production on the witches’ broom shoots and the number of witches’ broom infections on the trees under investigation. The five clones showed significant differences both in relation to their susceptibility to witches’ broom and in their yields. The different pruning frequencies, on the other hand, did not show any statistically provable differences in terms of the number of witches’ broom infections, nor did they influence the yields. It has become clear that neither the own studies nor the many research works undertaken at an international level were able to find a fundamental solution to the witches’ broom problem. Agriculture using the principles of successional agroforestry systems could represent a long-term perspective for land use in these areas, with the emphasis on more than short-term economic, social or structural objectives.

Texte intégralDenna rapport sammanfattar ett kandidatexamensarbete inom Hållbar energiteknik, som har utförts av två teknologer på Kungliga Tekniska Högskolan i Stockholm år 2014. I dagens situation är elnätet i Bolivia begränsat både geografiskt och tillförlitlighetsmässigt, och nästan hälften av landets invånare boendes på landsbygden lever utan tillgång till elektricitet. Tillgång till elektricitet leder till en ökad livsstandard, och ökar också möjligheterna till ett utvecklat, mer integrerat och hållbart samhälle. Målet med detta projekt var att dimensionera ett energisystem med en Stirlingmotor, anpassad för hushåll på landsbygden i låglänta områden i Bolivia. Stirlingmotorn värms upp externt och har en hög energieffektivitet, samt kan drivas av en stor mängd olika bränslen. I denna studie har motorn varit tänkt att drivas genom förbränning av biomassa. Biomassa, som är ett förnybart bränsle, finns det stor tillgång till i Bolivia. För att kunna modellera energisystemet behövdes först elektricitetsbehovet undersökas, sedan behövde Stirlingmotorns teknik kartläggas och analyseras. Resultatet blev en konceptuell modell över energisystemet som simulerades och beräknades i mjukvaruprogrammet HOMER. I simulationen beräknades två fall, ett system med en 2 kWel Stirlingmotor i kombination med en 1 kWel för drift under högtrafiktimmar, och ett system med en 3 kWel Stirlingmotor. Beräkningarna visar att en 3 kWel motor, med elektrisk verkningsgrad på 15 %, ihopkopplad med två batterier på 6 kWh kan leverera elektricitet till runt 30 hushåll. I systemet med en 2 kWel och en 1 kWel motor, båda med samma verkningsgrad som föregående, kan elektricitetsbehovet mötas om systemet backas upp med 25 stycken 6 kWh-batterier. Systemet med två motorer kombinerade erbjuder en mer flexibel och resurseffektiv lösning, och förbrukar 21 % mindre mängd biomassa än motorn på 3 kWel. Däremot kräver det tvåmotoriga systemet ett större engagemang från användarna. Slutsatsen blev att Stirlingmotorer är en genomförbar lösning för elektrifiering på landsbygden i Bolivia. Dock finns det ett flertal hinder angående Stirlingmotorer som behöver lösas innan motorn kan nå ett kommersiellt genombrott.
