    2010-01-01

    Full Text Available This article analyzes the main problems that the new Political Constitution of Bolivia is facing before being implemented, once it was approved on February 2009. In addition, it also studies how the constitutional provisions were negotiated in order to make the constitutional referendum viable. What were the political conflicts in the critical juncture 2008-2009, and what kind of reflection should be considered as to how the new emerging regional and local governments—together with its decentralized structures—are able to renew democracy in Bolivia within the framework of the Plurinational State? The multiple challenges ahead are highly difficult to confront from democratic theory perspectives.

  3. Bolivia: A Gasified Democracy

    Directory of Open Access Journals (Sweden)

    Willem Assies

    2004-04-01

    Full Text Available In October 2003 a wave of popular protest  brought down the Sánchez de Lozada government  in Bolivia. The intention to export natural gas to  the United States and Mexico triggered the protests, but actually stood for widespread discontent  with the Sánchez de Lozada government, the  preceding governments and the economic policies  pursued since 1985. The events belie the opinion  of various students of the Latin American democratic transitions who held that Bolivian democracy  was on its way towards consolidation and suggest that the recent inquiries into the quality of Latin  American democracies may point a way ahead in  rethinking democracy in the region. Taking such  assessments as a reference, this article reviews the  ‘gas war’ and looks at the Bolivian political regime as it has functioned over the past decades. It  will be argued that the ‘pacted democracy’, that  until now sustained institutionality, and the economic model adopted in 1985 have excluded an  important part of the population, both in political terms and where poverty alleviation and equity is  concerned. Increasing popular protest has been  met with increasing repression, which gradually  turned Bolivia into a ‘democradura’, or a ‘gasified  democracy’ that relies on teargas and bullets to  uphold itself. At present the country finds itself at  a crossroads. It either may reinvent democracy or  become an institutionalized ‘democradura’. Resumen: Bolivia: una democracia gasificadaEn octubre de 2003 una ola de protesta popular  llevó a la caída del gobierno de Sánchez de Lozada en Bolivia.

    Smith, P.

    1997-12-01

    The author summarizes changes which have occurred in Bolivia in the past year which have had an impact on renewable energy source development. Political changes have included the privatization of power generation and power distribution, and resulted in a new role for state level government and participation by the individual. A National Rural Electrification Plan was adopted in 1996, which stresses the use of GIS analysis and emphasizes factors such as off grid, economic index, population density, maintenance risk, and local organizational structure. The USAID program has chosen to stress economic development, environmental programs, and health over village power programs. The national renewables program has adopted a new development direction, with state projects, geothermal projects, and private sector involvement stressed.

    2008-01-01

    This report looks at Bolivia's main economic indicators over the past year (mid-2006 to mid-2007), noting improvements in growth, fiscal balances, balance of payments, and international reserves. These improvements were largely due to government policies and choices, such as increased hydrocarbons royalties and control over the hydrocarbons sector, and have allowed the government to embark on a number of programs targeting the poor and landless. The report also notes that Bolivia faces many challenges: expansion of land reform, more rapid growth and poverty reduction, the reduction of regional and demographic disparities, and an accelerated diversification of the economy away from hydrocarbons and minerals.

  17. The oil and gas market in Bolivia

    Energy Technology Data Exchange (ETDEWEB)

    2000-06-01

    Bolivia is becoming an important link in the South American energy trade given its large potential for oil and natural gas and the commissioning of the Bolivia-Brazil pipeline. Yacimientos Petroliferos Fiscales Bolivianos (YPFB) is the national oil and gas company in Bolivia. It has undergone a capitalization program and its exploration and production division was divided into two and sold to the private sector under the new names of Empresa Petrolera Andina SAM and Empresa Petrolera Chaco SAM. Shares from this division also went to the Bolivian people as part of a pension fund plan. Half of the transport and distribution division was also purchased in a joint venture. Major gas discoveries in August 1999 has prompted Bolivia to export large quantities of natural gas, primarily to Brazil's southern region, where demand has been exploding and a growing supply of Bolivian gas is much needed. This increased demand for natural gas has forced both Brazil and Bolivia to explore for other sources of gas and to conduct feasibility studies regarding the construction of gas pipelines. The recently constructed Santa Cruz-Rio Grande pipeline will not be sufficient to meet the growing demand. All the oil and gas sector investment from the private sector goes to the Bolivian government. Under Bolivian law, foreign companies are obliged to retain local representation for investment contracts, direct sales, and all government agency purchases.refs.

    1992-05-11

    This paper reports that state oil companies of Brazil and Bolivia have signed an agreement outlining the route for a 2,270 km pipeline system to deliver natural gas from Bolivian fields to Southeast Brazil. The two sides currently are negotiating details about construction costs as well as contract volumes and prices. Capacity is projected at 283-565 MMcfd. No official details are available, but Roberto Y. Hukai, a director of the Sao Paulo engineering company Jaako Poyry/Technoplan, estimates transportation cost of the Bolivian gas at 90 cents/MMBTU. That would be competitive with the price of gas delivered to the Sao Paulo gas utility Comgas, he the. Brazil's Petroleos Brasileiro SA estimates construction of the pipeline on the Brazilian side alone with cost $1.2-1.4 billion. Bolivia's Yacimientos Petroliferos Fiscales Bolivianos (YPFB) is negotiating with private domestic and foreign investors for construction of the Bolivian portion of the project.

  10. The Decolonization of Bolivia's Antinarcotics Policy?

    Directory of Open Access Journals (Sweden)

    Alba Hesselroth

    2016-03-01

    Este artículo sostiene que, en el siglo XX, se desarrolló una forma peculiar de colonización en la política antinarcótica de Bolivia, compuesta por rasgos parecidos a los del colonialismo externo e interno. Por una parte, las instituciones internacionales y los Estados Unidos lograron imponer en el país un sistema de control y prohibición del cultivo y consumo de la hoja de coca. Por otra parte,  la élite gobernante apoyada por los EE.UU. impuso su poder y dominio sobre los cocaleros al introducir esta prohibición  y promover la erradicación forzosa de la coca con el auspicio de EE.UU., poniendo en severo peligro los derechos de los  cocaleros. A diferencia de anteriores gobiernos que aceptaron pasivamente las decisiones tomadas en foros internacionales acerca de la clasificación de la hoja de coca como droga ilegal y siguieron con rigor las instrucciones de los EE.UU. acerca de la erradicación de la coca, el gobierno de Evo Morales está actuando para cambiar la situación  en un doble esfuerzo internacional y nacional. Analizando las políticas de este gobierno entre 2006-2014, este artículo sostiene que en el manejo de la política antinarcótica está siguiendo un proceso particular de descolonización para defender los usos tradicionales de la hoja de coca y proteger los derechos sociales, económicos y culturales de las poblaciones andinas involucradas en su producción y/o consumo, y promover el desarrollo económico de las áreas donde se cultiva.

    Full Text Available Introduction: Neural Tube Defects (NTD are the second congenital malformation, second only to cardiac malformations. Myelomeningocele (MMCL is the most frequent NTD and the more complex. In Bolivia, like in many countries in South America, the low socio economical level of the population increases its incidences and complicates its management. Materials and Methods: Retrospective study of 70 cases of MMC at Hospital Universitario Japonés (HUJ, Santa Cruz de la Sierra, between 2008-2011. Sixty had surgery. Results: Prenatal care in 27 women (38.6%, positive diagnosis for spinal disraphism in 2 (7.4%. The child arrived after 24 hours of birth (65.5%. Lumbosacral lesion (64.3%. Of those 67.2% were open, with 32.9% evidencing partial motor lesion in contrast with 47.1% who were paraplegic bellow the level of the lesion. Three children were not operated because they had complex and severe malformations associated to the MMCL. The most common surgical complications were; wound dehiscence or infection (16.6%, CSF fistula (10% CNS infection (11.7%. Mortality and specifically postoperative mortality were 7.1% y 3.3%, respectively. Hydrocephalus wass evident in 80% of the patients who were operated, they received a VP shunt medium pressure. Nine patients who had long term follow up presented with tethered cord. Conclusions: A characteristic, delayed referral. No gender predominance. Majority of cases were lumbar or lumbar sacral. Mortality similar to what is reported in the literature. Few patients came for follow up. MMCL is a pathology that requires concentrated attention by the national authorities. A multi center and multi national study will improve our management of these patients.

  13. Oil and gas market report. Bolivia. Panorama and perspective for business

    Energy Technology Data Exchange (ETDEWEB)

    Van Mourik, J.A.M.

    1999-10-01

    Bolivia, with its large oil and natural gas potential, is becoming an increasingly important link in South American energy trade. With new fields and pipeline construction, the nation is becoming the natural gas hub for the Southern Cone. In 1998, Bolivia experienced 4,7% GDP growth, the fastest in South America, and Bolivia's best performance since 1988. In addition, Bolivia brought its inflation rate to a 2-decade low of 4,4 %. In addition to tight global capital markets, investments also is expected to decrease due to the completion of the Bolivia to Brazil gas pipeline. This extremely capital-intensive project accounted for a significant portion of Bolivia's investment for 1998 and 1999. Bolivia has made significant economic improvements over the past few years by adopting a series of free market policies. The mayor improvements in economic growth have been made possible primarily through the government's unique capitalization program of key national industries. In addition to the Capitalization Program, Bolivia's economic growth is a result of its involvement in several free trade associations. Bolivia, as well as Chile, is an associate partner of the Mercosur, whose members include Argentina, Brazil, Paraguay and Uruguay. Bolivia is also member of the Andean Pact, which comprises Peru, Colombia, Ecuador and Venezuela. Bolivia's unique involvement in both of these trade groups is allowing it to become an important cornerstone in the integration of the South American continent. Specifically, Bolivia is increasingly becoming an important transport hub within the continent. Energy is one of the main products Bolivia is attempting to transport. According to the government, nearly $5 billion of investment is needed by 2005 so Bolivia can succesfully develop its oil and gas reserves, build pipelines, and construct power plants if it wishes to emerge as the regional hub.

    Full Text Available Abstract Background The aim of this study was to document the types of diseases treated by the use of medicinal plants, their main applications and also to have a report of the major diseases treated at the Hospital of San Pablo de Huacareta (Chuquisaca Bolivia. Methods We conducted semi-structured interviews on the use medicinal plants with 10 local informants, and categorized the kinds of diseases treated by traditional medicine. We obtained reports of cases treated at the Hospital of Huacareta in order to compare the use frequency of traditional medicine and allopathic medicine for the treatment of recurrent diseases in the area. Results Our survey identified 258 traditional medicine uses, spanning a total of 13 diseases categories and including 91 native and exotic plant species and one unidentified sample plant type. Gastrointestinal disorders (55% were most frequently treated with medicinal plants, followed by afflictions of the musculoskeletal system (25% and dermatological disorders (24%. Hospital information indicates that the most common diseases are acute respiratory infections (47% and acute diarrheal diseases (37%. The herbal remedies were mostly used in the form of teas and decoctions. The informants used mainly native plant species, although exotic species has been introduced to the pharmacopoeia. Conclusions The treatment of gastrointestinal disorders is the primary objective of the medical ethnobotany of the inhabitants of Huacareta, while respiratory system diseases are mostly treated in the hospital. Looking at the data from the Hospital records we can infer that gastrointestinal disorders are among the most common diseases in the study area. For most respondents, traditional medicine is a reliable choice for the care of their illnesses. However, the preference of the population for either traditional medicine or allopathic medicine needs to be clarified in future comparative studies to obtain more convincing results. The

    Dabdoub, Carlos F.; Dabdoub, Carlos B.; Villavicencio, Ramiro; Quevedo, Germán

    2014-01-01

    Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

    2015-02-24

    This study presents monthly and annual climate maps for relevant hydroclimatic variables in Bolivia. We used the most complete network of precipitation and temperature stations available in Bolivia, which passed a careful quality control and temporal homogenization procedure. Monthly average maps at the spatial resolution of 1 km were modeled by means of a regression-based approach using topographic and geographic variables as predictors. The monthly average maximum and minimum temperatures, precipitation and potential exoatmospheric solar radiation under clear sky conditions are used to estimate the monthly average atmospheric evaporative demand by means of the Hargreaves model. Finally, the average water balance is estimated on a monthly and annual scale for each 1 km cell by means of the difference between precipitation and atmospheric evaporative demand. The digital layers used to create the maps are available in the digital repository of the Spanish National Research Council.

    Full Text Available Since early in 2006, the republic of Bolivia has been ruled by the first indigenous president in that country’s history: the Aymara Evo Morales, union leader and first name in the ballot of the so-called “Movement for Socialism” (MAS. His political rise, electoral victory and government program have drawn considerable attention from international mass media and been the subject of valuable political and sociological analyses. From the perspective of comparative anthropology, the process can be understood as an instance, in the Andean cultural context, of what Anthony Wallace called a “revitalization movement,” triggered by the convergence, at a juncture of crisis begun in 1997, of a number of historical conditions of variable duration in Bolivia as a national project.

    Desde comienzos de 2006, la república de Bolivia cuenta con el primer presidente indígena de su historia: el aymara Evo Morales, dirigente sindical y cabeza de lista del llamado “Movimiento al Socialismo” (MAS. Su ascensión política, victoria electoral y programa de gobierno han llamado mucho la atención de los medios informativos internacionales y han sido objeto de valiosos análisis políticos y sociológicos. Desde la perspectiva de una antropología comparada, el proceso se ajusta bien, en el contexto cultural andino, a lo que Anthony Wallace llamara un “movimiento de revitalización”, desencadenado por la convergencia, en un periodo de crisis iniciado en 1997, de varias condiciones estructurales de duración histórica variable en Bolivia como proyecto nacional.

    Land-cover change in eastern lowland Bolivia was documented using Landsat images from five epochs for all landscapes situated below the montane tree line at approximately 3000 m, including humid forest, inundated forest, seasonally dry forest, and cloud forest, as well as scrublands and grasslands. Deforestation in eastern Bolivia in 2004 covered 45,411 km2, representing approximately 9% of the original forest cover, with an additional conversion of 9042 km2 of scrub and savanna habitats representing 17% of total historical land-cover change. Annual rates of land-cover change increased from approximately 400 km2 y(-1) in the 1960s to approximately 2900 km2 y(-1) in the last epoch spanning 2001 to 2004. This study provides Bolivia with a spatially explicit information resource to monitor future land-cover change, a prerequisite for proposed mechanisms to compensate countries for reducing carbon emissions as a result of deforestation. A comparison of the most recent epoch with previous periods shows that policies enacted in the late 1990s to promote forest conservation had no observable impact on reducing deforestation and that deforestation actually increased in some protected areas. The rate of land-cover change continues to increase linearly nationwide, but is growing faster in the Santa Cruz department because of the expansion of mechanized agriculture and cattle farms.

  7. Searching for Status: New Elites in the New Bolivia

    Full Text Available This essay argues that those strategies enabling the recognition and distinction of the elite in Bolivia have collapsed since Evo Morales assumed the country’s presidency in early 2006. Not only have new political elites taken power, the established and inherited societal stratifications have also been affected. Reviewing three emergent groups potentially occupying new elite positions – the progressive blanco-mestizos, the wealthy urban indigenous sectors, and the social movement leaders with their politicized cadres – it is argued that in today’s Bolivia, the political dimensions of anti-elitism have raided the traditional material and culturalsymbolic domains of elite distinction. The political dimensions of anti-elitism might have altered or even largely disqualified the indicators traditionally considered valid in the material and culturalsymbolic domains. Resumen: A la búsqueda de status: las nuevas élites en la nueva BoliviaEn este ensayo se sostiene que en Bolivia las estrategias que permiten el reconocimiento y prestigio de las élites se han derrumbado desde que Evo Morales asumiera la presidencia del país a principios de 2006. No solamente nuevas élites políticas han asumido el poder, sino además se han visto afectadas las estratificaciones sociales establecidas. En la revisión de tres grupos emergentes que ocuparán potencialmente las posiciones de la nueva élite – los mestizos blancos progresistas, los sectores indígenas urbanos ricos y los líderes de movimientos sociales con sus cuadros politizados –, aquí se sostiene que en la Bolivia de hoy las dimensiones políticas del anti-elitismo se han apropiado del material tradicional y los dominios culturales y simbólicos de las distinciones de élite. Las dimensiones políticas del anti-elitismo pueden haber alterado e incluso descalificado en gran parte los indicadores considerados tradicionalmente válidos en los dominios material y simbólico-cultural.

    Bolivia is currently undergoing a series of healthcare reforms centred around the Unified Family, Community and Intercultural Health System (SAFCI), established in 2008 and Law 475 for Provision of Comprehensive Health Services enacted in 2014 as a first step towards universal health coverage. The SAFCI model aims to establish an intercultural, intersectoral and integrated primary health care (PHC) system, but there has not been a comprehensive analysis of effective strategies towards such an end. In this systematic review, we analyse research into developing PHC in Bolivia utilizing MEDLINE, the Virtual Health Library and grey literature from Pan American Health Organization/World Health Organization's internal database. We find that although progress has been made towards implementation of a healthcare system incorporating principles of PHC, further refining the system and targeting improvements effectively will require increased research and evaluation. Particularly in the 7 years since establishment of SAFCI, there has been a dearth of PHC research that makes evaluation of such key national policies impossible. The quantity and quality of PHC research must be improved, especially quasi-experimental studies with adequate control groups. The infrastructure for such studies must be strengthened through improved financing mechanisms, expanded institutional capacity and setting national research priorities. Important for future progress are improved tracking of health indicators, which in Bolivia are often out-of-date or incomplete, and prioritization of focused national research priorities on relevant policy issues. This study aims to serve as an aid towards PHC development efforts at the national level, as well as provide lessons for countries globally attempting to build effective health systems accommodating of a multi-national population in the midst of development.

While some scholars suggest that an 'organic link" exists between these conflicts. they have yet to clearly specify the conditions and mechanisms through which such a link can form. Examining cases in Bolivia at the turn of the twenty-first century. I argue that struggles against exploitation and dispossession do not merely converge when facing a common oppressor. but also as the changing forms and geographies of exploitation and dispossession bring people together in more proximate locations. I illustrate that the changing means through which Bolivia was incorporated into the global economy enhanced levels of marginalization and subsequently resulted in patterns of migration that led to a convergence of peasant and proletarian struggles. As both segments of Bolivian society were excluded from the country's major economic sectors. they migrated to the places where they thought they could best satisfy their livelihood needs. But as people continually struggled to meet these needs, these places became spaces of marginalization, and eventually, spaces of resistance.

    Until recently, urban yellow fever had not been reported from the Americas since 1954, but jungle yellow fever increasingly affects forest dwellers in Bolivia, Brazil, Colombia, Ecuador, and Peru. The reinvasion by Aedes aegypti of cities in the Americas now threatens to urbanize yellow fever. After yellow fever infection was identified in a resident of Santa Cruz, Bolivia, in December 1997, all subsequent suspected cases were investigated. Active surveillance of yellow fever was introduced in the Santa Cruz area, with hospitals and selected urban and rural health centers reporting all suspected cases. Patients were serologically screened for yellow fever, dengue, hepatitis A and B, and leptospirosis; clinical and epidemiological data were collected from patients' records and through interviews; and a population-based serosurvey was conducted in the neighborhood of one case. Between December 1997 and June 1998, symptomatic yellow fever infection was confirmed in 6 residents of Santa Cruz, of whom 5 died. 5 lived in the southern sector of the city. 2 cases did not leave the city during their incubation period, and 1 had visited only an area in which sylvatic transmission was deemed impossible. Of the 281 people covered in the serosurvey, 16 (6%) were positive for IgM antibody to yellow fever. Among 5 people for whom that result could not be explained by recent vaccination, there were 2 pairs of neighbors. This instance of urban yellow fever transmission was limited in both time and space.

  18. Impacts of Unsustainable Mahogany Logging in Bolivia and Peru

    2004-06-01

    Full Text Available Although bigleaf mahogany [Swietenia macrophylla King (Meliaceae] is the premier timber species of Latin America, its exploitation is unsustainable because of a pattern of local depletion and shifting supply. We surveyed experts on the status of mahogany in Bolivia and Peru, the world's past and present largest exporters. Bolivia no longer has commercially viable mahogany (trees > 60 cm diameter at breast height across 79% of its range. In Peru, mahogany's range has shrunk by 50%, and, within a decade, a further 28% will be logged out. Approximately 15% of the mahogany range in these two countries is protected, but low densities and illegal logging mean that this overestimates the extent of mahogany under protection. The international community can support mahogany conservation by funding park management and by encouraging independent verification of the legality of mahogany in trade. Our findings demonstrate that a systematic expert survey can generate reliable and cost-effective information on the status of widespread species of concern and help to inform appropriate management policy.

    2015-04-01

    Magmas erupted at Uturuncu volcano (South Bolivia) comes from the Altiplano-Puna Magma Body (APMB, Chile-Bolivia), a crustal massive body of 80 km long by 10 km thick located at ~ 35 km depth named. Recent magneto telluric surveys reveal a resistivity lower than 1 ohm.m due to the presence of melt which could result in the reactivation of the volcano. In order to better constrain the resistivity profiles and thus the conditions of magma storage of the APMB, we have performed in situ electrical measurements on natural dacites and andesites from Uturuncu with a 4-wire set up in a piston cylinder and internally heated pressure vessel. The range of temperature (500 to 1300°C), pressure (0.3 to 2 Gpa), and the various water contents covers the respective ranges occurring at natural conditions. The results show that the conductivity increases with the temperature and the water content but slightly decreases with the pressure. Then a model was built from these results so as to help in (i) interpreting the electrical signature of natural magmas, (ii) constraining their conditions (chemical composition, temperature, pressure, water content, melt fraction) from the source to the storage location and (iii) providing information on the interior structure of a volcano and its reservoir.

    Full Text Available Chagas disease is a major public health problem in Bolivia. In the city of Cochabamba, 58% of the population lives in peripheral urban districts ("popular zones" where the infection prevalence is extremely high. From 1995 to 1999, we studied the demographics of Chagas infections in children from five to 13 years old (n = 2218 from the South zone (SZ and North zone (NZ districts, which differ in social, environmental, and agricultural conditions. Information gathered from these districts demonstrates qualitative and quantitative evidence for the active transmission of Trypanosoma cruzi in urban Cochabamba. Seropositivity was high in both zones (25% in SZ and 19% in NZ. We observed a high risk of infection in children from five to nine years old in SZ, but in NZ, a higher risk occurred in children aged 10-13, with odds ratio for infection three times higher in NZ than in SZ. This difference was not due to triatomine density, since more than 1,000 Triatoma infestans were captured in both zones, but was possibly secondary to the vector infection rate (79% in SZ and 37% in NZ. Electrocardiogram abnormalities were found to be prevalent in children and pre-adolescents (SZ = 40%, NZ = 17%, indicating that under continuous exposure to infection and re-infection, a severe form of the disease may develop early in life. This work demonstrates that T. cruzi infection should also be considered an urban health problem and is not restricted to the rural areas and small villages of Bolivia.

  2. Bolivia: New Presidential Electoral System and Political Parties Coordination

    Directory of Open Access Journals (Sweden)

    Mario Torrico

    2015-01-01

    Full Text Available This article analyzes the incentives generated by presidential electoral systems in Bolivia. The system that was in place until 2005 led to the formation of coalition governments that aimed at giving the Executive the majority in Congress. However, these coalitions gradually lost the electorate confidence, and citizens sought alternative political options to major parties from the early nineties on, giving rise to a social dissatisfaction with democracy. This, in turn, led to the resignation of Sánchez de Lozada and, later, to the triumph of Evo Morales. The new electoral system for electing the president, included in the 2009 Constitution, increases the likelihood that the elected government does not have a majority in Congress. Similar situations in the past led to political crisis and anticipation of elections. In a more favorable context characterized by greater satisfaction with democracy and their parties, the challenge is to take decisions inclusively, something unprecedented in Bolivian politics.

    Mercury contamination caused by the amalgamation of gold in small-scale gold mining is an environmental problem of increasing concern, particularly in tropical regions like the Amazon, where a new boom of such gold mining started in the 1970s. In Brazil, research into these problems has been carried out for many years, but there is no available data for Bolivia. The present paper surveys mercury contamination of a Bolivian river system in the Amazon drainage basin, measured in water, fish, and human hair. High concentrations in fish and human hair from consumers of carnivorous fish species are reported. The potential health risk from fish consumption was evident in people living downstream of gold-mining activities, but not in the mining population itself 24 refs, 3 figs, 2 tabs

    Mario Torrico

    2006-07-01

    Full Text Available This article seeks to dispute the explanations which assume that the process Bolivia is going through is similar to the processes other Latin–American countries are experiencing. These perspectives suggest the triumph of Evo Morales in the presidential elections of December 2005 was produced by the failure of the neoliberal policies carried out in this region during the period following the debt crisis of the eighties. Showing data that reveal that the bolivian economic performance in the neoliberal period was better compared to the performance of Argentina, Brazil and Mexico, this article offers an alternative explanation, which not denying the poverty of the bolivian majorities, asserts that the breakdown of the political system and the parties that alternated in power for twenty years is the main factor explaining the rise of the first indigenous president.

La literatura sobre economía ambiental insiste en la importancia de los factores físicos y sociales. Nos centramos en el último grupo de variables. Nuestro objetivo es identificar los mecanismos causales entre estos factores de riesgo y el problema de la deforestación. Con este fin, se presenta una estrategia de análisis para identificar mecanismos de causalidad espacial, basada en una secuencia de los multiplicadores de Lagrange.

    Full Text Available The objective of the present study is to examine the effects of several reproductive and demographic factors on child survival in Bolivia, one of the most impoverished nations in all of Latin America. We model the joint effects of maternal age, parity, pace of childbearing, duration of breastfeeding, and use of modern contraception on child mortality. Data for this research come from “Demographic and Health Survey” (DHS carried out during 1998. The results obtained in this paper support the evidence found in other studies: breastfeeding and the pace of childbearing are the most important reproductive patterns affecting child mortality risks, and their strong, consistent effects tend to persist even after the introduction of various socioeconomic variables as controls: short preceding birth intervals and short durations of breastfeeding increase the risk of death during the first two years of life.

    Full Text Available Voluntary Debt Reduction Operations. Bolivia, México, and Beyond This paper studies two recent voluntary operations of debt reduction: Bolivia's buy-back and Mexico's exchange of loans for bonds. This argued that the buy-back had a cost for Bolivia and, hence, it required a political decision when comparing this option to other alternative use of its scarce foreign exchange resources. In the case of Mexico, it is shown that the operation, which can be seen as an indirect buy-back, gave this country a rate of return on the use of its reserves, between 18% and 24%. The effects of both transactions on the debtor are examined, as well as on participating and non-participating creditor banks.

    Full Text Available In this article, I propose to outline the stories of violence between men and women from the countryside and low-income neighborhoods in the cities, based on 33 interviews conducted in Bolivia in the summers of 2005 and 2006. I don’t consider «violence» as a universal concept, but rather as a combination of representations related to widely distributed practices within society. I will clearly point out the commonalities between men and women, on the one hand, and among inhabitants of the country and the city, on the other. One of the common characteristics of all is the perception of living in a dangerous world. Women place a considerably bigger emphasis on dangers of a supernatural kind, as well as damages cause by symbolic violence, such as «badmouthing.» The inhabitants of poor urban environments place more importance on delinquent violence, and take measures to confront it. Both sexes refer to gender violence within the family, but it is women who cite lived experiences to that respect. In terms of causes for the violence, in the city both sexes seem to be incorporating into their imagination elements of academic discourse about structural violence

In the Pleistocene of South America, two genera are recorded: Pampatherium (with three species and Holmesina (with six species. In the Pleistocene palaeofauna of Tarija Valley (Bolivia one of the most conspicuous recorded taxa are the Cingulata, including Pampatheriidae. Until this contribution, all the remains were classified as P. typum and Pampatherium sp. Here we present a modern taxonomic revision of the Pampatheriidae of the Tarija Valley, based on previous collected and published material together with new materials obtained from fieldwork carried out during 2011-2013. The evidence indicates that a single species of Pampatheriidae is present in the Tarija Valley ( Pampatherium humboldtii , whereas the presence of P.  typum in discarded. From a chrono-stratigraphic point of view, the biochron of this species is restricted to the late Pleistocene.

  2. Visibility of latin american scientific publications: the example of Bolivia

    Directory of Open Access Journals (Sweden)

    Silvia Cristina Pabón Escobar

    2006-06-01

    Full Text Available The discussion on the state of the art of scientific publications in Latin American countries generally restricts itself to its supposedly low visibility. This affirmation is generally conditioned to the exclusive use of large international databases, mainly of the USA and Europe, which include thousands of scientific publications that have marginalized a large part of the scientific literature produced in peripheral countries. Given this fact of low visibility, it became imperative for some Latin American countries, beginning in the 90s (20th Century, to develop their own mechanisms of projection of the results of their own scientific production. The experiences constitute an example for countries that, having significant scientific production, still do not have the means to facilitate access to local scientific publications. Although Bolivia still remains distant from these initiatives, a series of studies were identified that show the existence of a tradition of publication in scientific magazines and interest in their visibility, on a local and international level, which demands attention to the most adequate mechanisms in order to carry this out.

    Alvizuri, Celso; Tape, Carl

    2016-09-01

    We present a catalogue of full seismic moment tensors for 63 events from Uturuncu volcano in Bolivia. The events were recorded during 2011-2012 in the PLUTONS seismic array of 24 broad-band stations. Most events had magnitudes between 0.5 and 2.0 and did not generate discernible surface waves; the largest event was Mw 2.8. For each event we computed the misfit between observed and synthetic waveforms, and we used first-motion polarity measurements to reduce the number of possible solutions. Each moment tensor solution was obtained using a grid search over the 6-D space of moment tensors. For each event, we show the misfit function in eigenvalue space, represented by a lune. We identify three subsets of the catalogue: (1) six isotropic events, (2) five tensional crack events, and (3) a swarm of 14 events southeast of the volcanic centre that appear to be double couples. The occurrence of positively isotropic events is consistent with other published results from volcanic and geothermal regions. Several of these previous results, as well as our results, cannot be interpreted within the context of either an oblique opening crack or a crack-plus-double-couple model. Proper characterization of uncertainties for full moment tensors is critical for distinguishing among physical models of source processes.

    Anisotropy in the upper mantle is often associated with mantle flow direction through the lattice preferred orientation of anisotropic minerals such as olivine in the upper mantle material. The flow of the mantle around subduction zones can be particularly complex, and thus difficult to explain. Because of its relationship to anisotropy, analysis of shear wave splitting measurements can help to answer questions regarding the upper mantle flow that surrounds subducting slabs. Here we present SK(K)S shear wave splitting measurements from a temporary broadband network (PLUTONS) of 33 stations deployed from April 2009 to October 2012 on the Altiplano plateau around Uturuncu volcano in Bolivia. The stations are spaced 10-20 km apart, providing a high spatial resolution of the region of the mantle directly below Uturuncu volcano. Despite the lack of numerous splitting results to analyze, preliminary measurements indicate a relatively consistent pattern of fast-polarization directions in a NW-SE orientation of about N80ºW. We think that it is likely that these observations come from anisotropy in the mantle wedge above the subducting Nazca plate indicating a direction of flow in the mantle wedge that is sub-parallel to the subduction direction of the Nazca plate. Although W-E flow beneath the subducting Nazca plate cannot be completely ruled out, these results appear to be consistent with the simple model of two-dimensional corner flow in the mantle wedge and slab-entrained mantle flow beneath the slab.

    2013-09-25

    The practice of neurosurgery in Bolivia began thousands of years ago with skull trepanation. This procedure dates from the earliest period of the Tiwanaku culture, a preInca civilization. Neurosurgical development in Bolivia has its origins in the late 19(th) century and can be divided in two stages. At the beginning, before the advent of neurosurgery as a discipline, some general surgeons performed procedures on the skull and brain. Formal neurosurgery in Bolivia was developed with the arrival of neurosurgeons trained in the United States and some countries of South America. The Bolivian Neurosurgical Society was created in 1975. Nowadays, our national society has 74 members. It is affiliated with the World Federation of Neurosurgical Societies and the Latin American Federation of Neurosurgical Societies. Presently, neurosurgery in Bolivia is similar to that seen in developed countries. In this sense, government programs should dedicate more financial support to establish specialized healthcare centers where the management of complex central nervous system lesions could be offered. In contrast, we believe that encouraging the local training of young neurosurgeons is one of the most important factors in the development of neurosurgery in Bolivia or any other country.

    Uruguay and Bolivia are two countries that show heterogenicity of the Latin American region, including the national income, the expenditure on health and the services for renal care. In Bolivia, there is manpower shortage for renal care with only 5 nephrologists per million people (pmp) and the prevalence of patients on dialysis is only 200 pmp. This is much lower than the mean prevalence rate of renal replacement therapy for Latin America as a whole. Uruguay on the other hand has more dedicated renal resources with 50 nephrologists pmp, and renal replacement therapy is provided to ~ 1,000 dialysis patients pmp. In November 2012, a collaborative project financed by the Uruguayan International Cooperation Agency was signed by both the Uruguay and Bolivia Ministries of Health, and the goal was to develop a comprehensive program for the prevention and management of all stages of chronic kidney disease (CKD) in Bolivia. The specific objectives were to: a) promote renal healthcare in the primary healthcare setting, b) identify kidney disease in populations at risk, and c) optimize patient care at all stages of CKD, including dialysis and transplantation supported with a national ESRD registry in Bolivia. As a first step, delegates from the Bolivian Health Ministry, visited Uruguay in April 2014, primarily to strengthen the development of tools required for developing and maintaining a national registry. In addition, during this visit, a meeting with the president of the Latin American Society of Nephrology and Hypertension (SLANH) culminated in designing a training program for peritoneal dialysis. This highly cooperative relationship is advancing the prevention and care of CKD in Bolivia and may serve as a model for international approaches to advance system level CKD care in countries with limited healthcare resources.

    Full Text Available Sajama National Park, the first protected area in Bolivia, includes five indigenous communities with a primary production base of pastoralism. The semi-arid region of the Central Andes is one of the most extreme areas of human occupation at 4200 meters altitude and affected by high climatic variability. This paper studies the relations between climate variability, resilience, biodiversity of pastures and pastoral production in Sajama National Park. We present a botanical study of palatable pasture herbs between two years, one humid (2006 and the other dry (2007. Thirty vascular plants were recorded. The number of species and the cover of iro (Festuca ortophylla peak in areas of intermediate disturbance; areas that are at a medium distance from camelid corrals. On the other hand, the cover of ephemeral plants between tussocks increases in high disturbance areas. This is interpreted as a result of the tradeoff between the damage of grazing and the benefit of the fertilization produced by the herding animals. The local people clearly perceive strong impacts of climate change, combined with changes in management and human pressures. The social dynamics and production management, combined with climate warming, water reduction, and the increasing variability of surface water regimes create potential risks for the local sustainability of pastoralism.

    Full Text Available Se presenta la experiencia de una política de salud democrática y participativa que pudo aplicarse exitosamente en Bolivia simultáneamente con la recuperación de la democracia después de 18 años de gobiernos de facto y dictaduras militares. Esta experiencia estuvo inspirada en los conceptos emergentes de la medicina social y tuvo como base una forma de concebir la participación popular en salud muy diferente a la tradicional que busca que la población coopere con los servicios. Lo que la experiencia boliviana señala es que son los profesionales del área de salud los que deben cooperar con la población en la conquista de sus reivindicaciones y derechos, uno de los cuales es el Derecho a la Salud. Se analiza el importante papel que cumplieron los Comités Populares de Salud por un lado y médicos especialmente capacitados por otro, para acometer una serie de movilizaciones que lograron impactos importantes como la desaparición del bocio endémico que afectaba al 65.5% de la población escolar, la reducción de la mortalidad infantil de 200 por mil a 75 en un período de 10 años, la desaparición de enfermedades inmunoprevenibles como la poliomielitis y el sarampión y otros avances importantes.

    Santa Fe is a Sn-Zn-Pb-Ag ore deposit located in the Oruro district, Central Andean Tin Belt, Bolivia. Mineralization occurs in veins and disseminations. It is hosted in Silurian shales and greywackes. The sedimentary sequence is folded and unconformably covered by a volcanic complex of the Morococala Formation, mainly constituted by tuffs of Miocene age. A wide Nº40 shear zone and two systems of fracture are developed. A Nº40 fracture system, dipping 60ºW, which hosts Sn and Zn minerals, and other in the same direction but dipping 75ºE, which is related to Zn-Pb-Ag veins. The mineralization is associated to intrusive felsic magmatism. Although there are not intrusive rocks in Santa Fe, a dyke and the felsic San Pablo stock occur at a distance of about 10 km. In the present work we describe the geology and mineralogy of the Santa Fe deposit. X-ray diffraction, scanning electron microscopy and electron microprobe analyses were used to characterize the minerals. Veins are filled with quartz and an ore mineral assemblage of cassiterite, sulfides and sulfosalts. Cassiterite constitutes the earliest formed mineralization. Preliminar microprobe analyses indicate that it is nearly pure, with negligible contents in Nb and Ta. Rutile occurs as a late phase associated with a late generation of cassiterite. It forms thin neddle-like crystals. In addition, Sn is also present in sulfides as stannite, stannoidite and kësterite. Other sulfides are pyrrhotite, pyrite, arsenopyrite, galena, sphalerite, marchasite and argentite. Bismuthinite and berndite are found nin trace amounts. Sulfosalts include tetrahedrite, myarhyrite, boulangerite, jamesonite, franckeite, zinckenite, cilindrite and andorite. Associated with the mineralization, several phosphate minerals are found filling cavities and small fractures. The most abundant are monacite (Ce,La,Nd,Th)PO4 and plumbogummite (PbAl3(PO4)2(OH)5•(H2O)). Crandallite CaAl3(PO4)2(OH)5•(H2O) and vivianite (Fe3+(PO4)2•8(H2O)) also

    Godoy, R A

    1984-01-01

    Basic demographic data of landless and landed peasants from the highlands and valley of Northern Potosi, Bolivia, are compared. Household size and crude birth rates are larger in the highlands than in the valley. Within the highland population, no statistically significant difference was observed between the age-specific fertility of landless and landed women, nor in the survivorship ratio of their offspring. The prevalence of exchange and reciprocity at the village level may be responsible for the absence of important differences in the fertility and mortality patterns of the landed and the landless. Information was obtained from a total of 333 households, which included a population of about 1700 people or 20% of the Jukumani ayllu (ethnic group). No relationship between altitude and human reproduction was noted among Jukumanis. Highland Jukumani women begin reproducing in their late teens; by their mid-20s only about 30% of the 21-25 year old female cohort remains childless. 2 major tax categories of people emerge in the area under consideration: taseros, the landed peasantry who are obligated to pay taxes, and kantu runas, the landless laborers who do not pay taxes. Tasero women are most fertile from their mid-20s until their mid-30s whild kantu runa women are more fertile later in life. Within the highland territory there are no statistically significant differences in the infant and child mortality patterns of taseros and kantu runas. The higher household size and crude birth rates of highlanders suggests that hypoxic stress may not depress fertility. Taseros and kantu runas differ in fertility patterns in degree rather than in kind. It is concluded that although differential access to natural resources may translate into slightly higher crude birth rates and child/woman ratios, it does not have much bearing on the fertility of women, or the mortality or household size of taxpayers and kantu runas. A possible explanation for the Jukumani anomaly may be the

    Paleoelevation histories from the central Andes in Bolivia have suggested that the geodynamic evolution of the region has been punctuated by periods of large-scale lithospheric removal that drive rapid increases in elevation at the surface. Here, we evaluate viable times and locations of material loss using a map-view reconstruction of the Bolivian orocline displacement field to forward-model predicted crustal thicknesses. Two volumetric models are presented that test assumed pre-deformation crustal thicknesses of 35 km and 40 km. Both models predict that modern crustal thicknesses were achieved first in the northern Eastern Cordillera (EC) by 30-20 Ma but remained below modern in the southern EC until ≤10 Ma. The Altiplano is predicted to have achieved modern crustal thickness after 10 Ma but only with a pre-deformation thickness of 50 km, including 10 km of sediment. At the final stage, the models predict 8-25% regional excess crustal volume compared to modern thickness, largely concentrated in the northern EC. The excess predicted volume from 20 to 0 Ma can be accounted for by: 1) crustal flow to the WC and/or Peru, 2) localized removal of the lower crust, or 3) a combination of the two. Only models with initial crustal thicknesses >35 km predict excess volumes sufficient to account for potential crustal thickness deficits in Peru and allow for lower crustal loss. However, both initial thickness models predict that modern crustal thicknesses were achieved over the same time periods that paleoelevation histories indicate the development of modern elevations. Localized removal of lower crust is only necessary in the northern EC where crustal thickness exceeds modern by 20 Ma, prior to paleoelevation estimates of modern elevations by 15 Ma. In the Altiplano, crustal thicknesses match modern values at 10 Ma and can only exceed modern values by 5 Ma, post-dating when modern elevations were thought to have been established. Collectively, these models predict that

  5. The emergence, growth and decline of political priority for newborn survival in Bolivia.

    2014-12-01

    Bolivia is expected to achieve United Nations Millennium Development Goal Four, reducing under-five child mortality by two-thirds between 2021 and 2025. However, progress on child mortality reduction masks a disproportionately slow decline in newborn deaths during the 2000s. Bolivia's neonatal mortality problem emerged on the policy agenda in the mid-1990s and grew through 2004 in relationship to political commitments to international development goals and the support of a strong policy network. Network status declined later in the decade. This study draws upon a framework for analysing determinants of political priority for global health initiatives to understand the trajectory of newborn survival policy in Bolivia from the early 1990s. A process-tracing case study methodology is used, informed by interviews with 26 individuals with close knowledge of newborn survival policy in the country and extensive document analysis. The case of newborn survival in Bolivia highlights the significance of political commitments to international development goals, health policy network characteristics (cohesion, composition, status and key actor support) and political transitions and instability in shaping agenda status, especially decline-an understudied phenomenon considering the transitory nature of policy priorities. The study suggests that the sustainability of issue attention therefore become a focal point for health policy networks and analyses.

    Research has demonstrated that prolonged duration of breastfeeding promotes child survival. This study examines the impact of unintended--mistimed or unwanted--pregnancy on breastfeeding duration. We use data from the 1990 Paraguay and 1994 Bolivia Demographic and Health Surveys and restrict our analysis to last-born, surviving children younger than 36 months from singleton births. To assess the association, unintended and intended pregnancies are compared by calculating incidence rates and adjusted hazard ratios (aHR) using survival analysis. Most children (approximately 95 percent) were breastfed initially, but the median duration of breastfeeding in Bolivia was five months longer than that in Paraguay (19 versus 14 months). A greater proportion of pregnancies were described as intended in Paraguay than in Bolivia (74 percent versus 45 percent). In adjusted analyses, unwanted and mistimed pregnancies were associated with slightly longer duration of breastfeeding (aHR = 0.9) than were intended pregnancies, but the association was not statistically significant. In this study, therefore, pregnancy intention was not an important factor in duration of breastfeeding in Bolivia or Paraguay.

    Full Text Available Migrant remittances are increasingly seen as a potential form of development in the global South, but the impact of international migration on sending regions is far from straightforward. In this article, I analyze migrant communities of origin in rural Bolivia as dynamic places that are constantly reproduced through connections with other places. I document the movement of migrant practices between Washington D.C. and Cochabamba and the influence of monetary and non-monetary flows on Bolivian cultural practices, politics, and development. I demonstrate how hometown associations and returning migrants have transferred organizational practices and political ideas about development from the United States to rural Bolivia. In addition, I explore migration’s role in struggles over belonging in Cochabamba, focusing on the efforts by migrants in Washington D.C. to stake their claim through transnational houses and collective remittance projects and on recent internal migration from other regions in Bolivia. Finally, I assess the sustainability of migrant-led development in Cochabamba. Although collaboration with migrants can strengthen the local state by providing more resources, it conditions the type of development that can take place and has yet to provide adequate opportunities for returning migrants or young people in rural Bolivia.

  17. The effectiveness of market-based conservation in the tropics: forest certification in Ecuador and Bolivia.

    Ebeling, Johannes; Yasué, Maï

    2009-02-01

    During the last decade, forest certification has gained momentum as a market-based conservation strategy in tropical forest countries. Certification has been promoted to enhance forest management in countries where governance capacities are insufficient to adequately manage natural resources and enforce pertinent regulations, given that certification relies largely on non-governmental organisations and private businesses. However, at present there are few tropical countries with large areas of certified forests. In this study, we conducted semi-structured stakeholder interviews in Ecuador and Bolivia to identify key framework conditions that influence the costs and benefits for companies to switch from conventional to certified forestry operations. Bolivia has a much greater relative area under certified forest management than Ecuador and also significantly more certified producers. The difference in the success of certification between both countries is particularly notable because Bolivia is a poorer country with more widespread corruption, and is landlocked with less access to export routes. Despite these factors, several characteristics of the Bolivian forest industry contribute to lower additional costs of certified forest management compared to Ecuador. Bolivia has stronger government enforcement of forestry regulations a fact that increases the cost of illegal logging, management units are larger, and vertical integration in the process chain from timber extraction to markets is higher. Moreover, forestry laws in Bolivia are highly compatible with certification requirements, and the government provides significant tax benefits to certified producers. Results from this study suggest that certification can be successful in countries where governments have limited governance capacity. However, the economic incentives for certification do not only arise from favourable market conditions. Certification is likely to be more successful where governments enforce

It was assessed the struggle between the take-or-pay obligations for the imported gas consumption against the necessity of an efficient and responsible hydroelectric system operation. An interruptible gas market seems the solution to avoid the uneconomic use of gas in the power sector. This will require a development of a quite complex price system, based upon a gas seasonal and spot market. (author). 5 refs, 4 figs, 1 tab

    In the year of 2003 the Brazilian government, as form of to stimulate the demand for natural gas in the country and to promote the success of the investment accomplished in the construction of the pipe line Bolivia-Brazil, it lowered the price of the Bolivian commodity' in US$0,85/MMBTU. In the end of 2005 and mainly in 2006, the current Bolivian president Evo Morales nationalized the energy reservations of your country. To main change it is related to the price of sale of the Bolivian input. The values stipulated in contract they were broken and new negotiations are in process. The maximum capacity of transport of natural gas was reached in 2007. However, before the crisis established due to the measure taken by the government from Bolivia, Brazil suspended the investments in compressors and the projections of increase of this capacity were stagnated. One of the forecasts was to increase in at least more 50% of the current capacity or even in 100% in a more promising scenery. Before this context this research makes the analysis of economical viability regarding the construction of the pipe line Bolivia-Brazil in agreement with three sceneries. The first of them suggests that the investments foreseen in compressors it was stopped and, this way, the pipe line will operate it ties the end of the amortization with your current maximum capacity. The second scenery already suggests that the investments were not interrupted, in other words, the current maximum capacity was overcome in 50%. Similarly to the previous ones, the third scenery makes reference the overrun of the current capacity in 100%. The methodology used for such an analysis it was lent of the financial mathematics and it is treated of the calculation of TIR and of VPL. Both studies show that in agreement with TIR (15%) and VPL the economical viability is satisfactory. The president of PETROBRAS is renegotiating the contract and the investments will probably be retaken. This measured it seeks to

    The Rio Pilcomayo ' Alto ' (Bolivia) and ' Superior ' (Bolivia, Argentina, and Paraguay) transport large quantities of sediment for the size of the basin. The Rio Pilcomayo ' Inferior ' (Argentina and Paraguay) carries little sediment. The large loads of the ' Alto ' and ' Superior ' must be considered before dams or irrigation projects are started. The shifting channel and flooding of the Rio Pilcomayo ' Superior ' also are problems to be considered before development. The Rio Pilcomayo ' Alto ' basin has relatively little sediment deposition whereas the ' Superior ' basin has considerable deposition. A part of the ' Superior ' channel is filled with sediment to the top of its banks. The upstream limit of filling is moving farther upstream each year causing the place of overbank flooding to move upstream also. (Woodard-USGS)

    Full Text Available From Enron to Evo is a long-term study of Enron and Shell’s construction of the Cuiabá pipeline in eastern Bolivia. The pipeline goes through the middle of the Chiquitano forest and affects a population of about 8,000. The project also has a negative impact on four critical ecoregions; the Gran Chaco and Cerrado, which are a mixture of grasslands and scattered trees, the Chiquitano dry forest, and the Pantanal wetlands. The Cuiabá pipeline has been highly contested by the thirty-four Chiquitano and two Ayoreo communities that live in the area. After years of field research, extensive interviews and document analyses, Dr. Hindery manages to expose the murky ways in which the hydrocarbon industry works in Bolivia. This is an industry where the powerful –mainly multinational oil companies and the Bolivian government– abuse the ecoregion and the indigenous populations that live on it.

  5. Reducing greenhouse gas emissions from tropical deforestation by applying compensated reduction to Bolivia

    Energy Technology Data Exchange (ETDEWEB)

    Silva-Chavez, G.A. [Environmental Defense, Wahington DC (United States)

    2005-07-01

    Bolivia's deforestation emissions from land use change, including deforestation, account for 82% of its total greenhouse gas emissions. In recent years, soybean production has been the main cause of deforestation. There are currently no policies in place that will lead to a reduction in its deforestation rate or associated carbon emissions in the near-future. This analysis shows that in today's carbon-constrained world, a standing tree already has a potentially greater financial value than soybean production. Based on the results of this analysis, it is expected that the break even price (BEP) of carbon in Bolivia will be USD 4.43 in 2005 and USD 9.50 in 2012. Compensated Reduction (CR) creates large-scale financial incentives needed for forest protection at the national level and allows developing countries access to the global carbon market.

    This study models various pathways linking maternal education and child nutritional status in Bolivia, using a national sample of children. Pathways examined include socioeconomic status, health knowledge, modern attitudes towards health care, female autonomy, and reproductive behavior. The data come from the 1998 Bolivia Demographic and Health Survey. Logistic regression results suggest that socioeconomic factors are the most important pathways linking maternal education and child nutritional status, and that modern attitudes about health care also explain the impact of education. Health care knowledge accounts for less of the effect of maternal education on child nutritional status, with autonomy being the weakest pathway. Other pathways, such as reproductive behaviors, appear to influence nutritional status independent of maternal education. Overall, the pathways examined accounted for 60 percent of the effect of maternal education on child nutritional status.

One aspect of these upheavals was the emergence of nationalist and regionalist discourses pitting the orient against the occident of the country, and vice versa. Such discourses were marked by strong ethnic overtones, accentuating either camba or colla identities. Nevertheless, such identity discourses have very different roots and reflect very different projects and class relations. Taking a lead from the «inverted fridge» metaphor –the fridge that generates warmth towards the «inside(r» and cold towards the «outside(r»– this paper seeks to elucidate the interrelation between the politics of nationalism/regionalism, ethnicity and class in contemporary Bolivia.

    Young adults 18 to 25 years old show the highest prevalence of marijuana use in Latin America. This study analyzes the changes in prevalence of marijuana use among university students in the Andean Community (Bolivia, Colombia, Ecuador, and Peru) from two studies carried out in 2009 and in 2012. Data were collected through representative two-stage samples of universities and students in the Andean Community. An online survey was administered using a standardized questionnaire. Prevalence was calculated for lifetime, past year, and past month. Marijuana was the most widely used illicit substance consumed among university students, in 2009 and in 2012. Past month prevalence among university students in 2009 in Colombia was 5.27%, in Peru 1.00%, in Ecuador 1.68%, and in Bolivia 0.76%. Past month prevalence in 2012 in Colombia was 7.14%, in Ecuador 3.67%, in Peru 1.62%, and in Bolivia 1.45% in 2012. Among university students in the Andean Community, past month prevalence increased among both males and females between 2009 and 2012 in most countries. Marijuana continues to be the most commonly used illicit drug in Latin American countries. Increases in prevalence among young adults could have important implications for national drug policy.

    Here we report a superbly preserved and profusely represented five-ichnotaxa dinosaur track assemblage near Icla village, 100 km southeast of Sucre, Bolivia. As preserved in reddish Jurassic-Cretaceous boundary aeolian sandstones, this rich and uncommon assemblage is, additionally, the oldest dinosaur tracksite for Bolivia. Four trackmakers were identified in the area: three quadrupedal and one bipedal, all of them with tracks of around 35 cm in lenght. One of the quadrupedals is represented by no less than five adult individuals (ichnotaxon A), and four purported juveniles (ichnotaxon B) walking in association. The other two quadrupedals (ichnotaxa C and D) involve four trackways, and the last, the bipedal trackmaker (ichnotaxon E), is represented by one trackway. The five ichnotaxa represented in the "Palmar de Tunasniyoj" could be tentatively assigned to the following trackmakers: Ichnotaxa A and B are assigned to basal stegosaurians; ichnotaxon C to a basal tyreophoran, perhaps related to the ankylosaur lineage; ichnotaxon D to the Ankylosauria, and ichnotaxon E to Theropoda. The Tunasniyoj assemblage, the oldest dinosaur tracksite for Bolivia, includes the oldest known evidence assigned to ankylosaurs and stegosaurs for South America.

    Full Text Available Unregulated selling practices, bad storage habits and the use of illegal pesticides in Bolivia are widespread, with increasing negative consequences on public health and the environment. The present study describes the selling, storage and use of legal, illegal and obsolete pesticides among pesticide retailers and farmers in Bolivia. A cross-sectional study was conducted on 191 pesticide-using farmers and 40 pesticide retailers. Data were gathered in 2009 in La Paz County, Bolivia. A questionnaire was used to evaluate pesticide handling practices and observational data on pesticide stocks and storage was assessed through direct visits on site. Banned, outdated and highly toxic pesticides were found stored on most smallholder farms. A mean of 299 g of pesticides was found on each farm, of which 60% were obsolete. Knowledge on pesticide toxicity and safe handling practices were lacking among both retailers and farmers, and poisonings were frequently reported. Significant figures of obsolete pesticides were found outside of the officially recognized dumping sites. This underlines the necessity of including the small but numerous amounts of pesticides stored at farms, when calculating a country’s total amount of obsolete pesticides. Better regulations of imports, sale and storage and an improved use of safety measures when handling pesticides needs to be urgently addressed.

    Full Text Available Abstract Background Pesticide use and its consequences are of concern in Bolivia due to an intensive and increasing use. Methods To assess the magnitude and reasons for occupational pesticide intoxication, a cross-sectional study with interviews and blood-tests was performed among 201 volunteer farmers from 48 villages in the temperate and subtropical valleys in the eastern part of the Andes Mountains in Bolivia. Of these 171 male farmers using pesticides in their agricultural production were used in the statistical analysis, including linear- and logistic regression analysis. Results This study documented a frequent use of the most toxic pesticides among farmers who have had almost no instructions in how to use pesticides and protect themselves against the dangers of intoxication, reflected in the hazardous practices used when handling pesticides. Symptoms of intoxications were common in connection with spraying operations. The risk of experiencing symptoms and the serum cholinesterase activity were influenced by whether or not organophosphates were used and the number of times sprayed. The experience of symptoms was moreover influenced by the hygienic and personal protective measures taken during spraying operations while this had no influence on the serum cholinesterase level. Conclusion The study showed that occupational pesticide intoxications were common among farmers and did depend on multiple factors. Pesticide use is probably one of the largest toxicological problems in Bolivia, and a coordinated action by authorities, society and international bodies is needed to limit the number of intoxications and the environmental pollution.

    Full Text Available Using data on informal market loans in the Cochabamba region of Bolivia, we test the hypothesis that monetary reform in the 1985-87 period resulted in a dedollarization of the economy. A theoretical model of the loan market suggests variables to be examined in the empirical analysis. A PROBIT model of the probability of dollar-denominated loans is estimated as a function of Bolivian inflation, exchange-rate depreciation, and exchangerate volatility. In addition, policy reforms are modeled with dummy variables that switch on at the date of the reforms. In addition to the PROBIT estimates, we aggregate monthly average time series data for the informal market and investigate the hypotheses studied in this alternative data set.The evidence from the informal loan market suggests that the Bolivian stabilization plan was associated with an increase in dollarization rather than a decrease. Several possible reasons for this result are discussed, including a lack of credibility of the announced plan. Dolarization and Monetary Reform. Evidence from the Cochabamba Region of Bolivia

    The analysis of drainage net allows to identify features of relief symmetry and/or not symmetry and know its morpho structure (high and low structural). The interpretation of relief and drainage texture elements at Landsat/ETM7+ satellite images allows to identify the geo environmental zoning. The integration between morpho structural maps and geo environmental zones maps produces sustainable capacity maps. In the Bolivia-Brazil Gas Pipeline influence area, the evaluation of sustainable capacity shapes the interrelation among gas pipeline and physical environment and allows classify more geological and geotechnical favorable areas to gas pipeline maintenance. Gas pipeline regions located at 'High Sustainable Capacity' need few maintenance. However, gas pipeline regions at 'Low/Very Low Sustainable Capacity' need constant investment and monitoring.

  14. Without Distinguishing Color or Profession: Culture, Vatican II and the Long-Term Development of Credit Institutions in Bolivia

    Directory of Open Access Journals (Sweden)

    Brian Norris

    2016-03-01

    Full Text Available By the late 20th and early 21st century, credit institutions in Bolivia had become more complex, resilient and popular that at any time previously in its history. Traditional economics analyses emphasize incentives created by laws such as those promulgated by the Kemmerer mission in Bolivia in the 1920s and 30s, or material factors, such as transportation costs. Yet neither of these explanations offers a compelling explanation for the magnitude of the flourishing of popular and complex credit institutions in Bolivia after the 1960s. Cultural changes, however, might offer a compelling complement to legal and material explanations of credit development. Vatican II represented an important mass change in Bolivian culture, and institutions associated with these reforms ushered in a new era of credit institution development in the country. A finales del siglo XX y comienzos del XXI, las instituciones crediticias en Bolivia se volvieron más complejas, elásticas y populares que en cualquier otro momento de su historia. Los análisis económicos tradicionales ponen de relieve los incentivos creados por leyes como las promulgadas por la misión Kemmerer en Bolivia en las décadas de 1920 y 1930, o factores materiales, tales como los costos de transporte. Con todo, ninguna de estas explicaciones ofrece una explicación convincente de la importancia del florecimiento de instituciones crediticias populares y complejas en Bolivia después de la década de 1960.  No obstante, los cambios culturales podrían ofrecer un complemento de peso a las explicaciones legales y materiales del desarrollo del crédito. El Concilio Vaticano II representa un importante cambio en la cultura boliviana, y las instituciones asociadas con sus reformas marcan el comienzo de una nueva era en el desarrollo de la institución crediticia en el país.

    BACKGROUND In Bolivia, in 2008, the under-five mortality rate is 54 per 1000 live births. Diarrhea causes 15% of these deaths, and 40% of pediatric diarrhea-related hospitalizations are caused by rotavirus illness (RI). Rotavirus vaccination (RV), subsidized by international donors, is expected to reduce morbidity, mortality, and economic burden to the Bolivian state. Estimates of illness and economic burden of RI and their reduction by RV are essential to the Bolivian state’s policies on RV program financing. The goal of this report is to estimate the economic burden of RI and the cost-effectiveness of the RV program. METHODS To assess treatment costs incurred by the healthcare system, we abstracted medical records from 287 inpatients and 6,751 outpatients with acute diarrhea between 2005 and 2006 at 5 sentinel hospitals in 4 geographic regions. RI prevalence rates were estimated from 4 years of national hospital surveillance. We used a decision-analytic model to assess the potential cost-effectiveness of universal RV in Bolivia. RESULTS Our model estimates that, in a 5-year birth cohort, Bolivia will incur over US$3 million in direct medical costs due to RI. RV reduces, by at least 60%, outpatient visits, hospitalizations, deaths, and total direct medical costs associated with rotavirus diarrhea. Further, RV was cost-savings below a price of US$3.81 per dose and cost-effective below a price of US$194.10 per dose. Diarrheal mortality and hospitalization inputs were the most important drivers of rotavirus vaccine cost-effectiveness. DISCUSSION Our data will guide Bolivia’s funding allocation for RV as international subsidies change. PMID:21624421

    Full Text Available This study examined environmental and socioeconomic outcomes of a water project in rural Bolivia, and sought insights on how and why its planning was so flawed. The project destroyed an ancient, sustainable irrigation system, and replaced it with one that provides insufficient and diminishing quantities of water to many fewer people, appears to be causing land degradation and groundwater depletion, and has fueled conflicts. The study shows that even relatively small, NGO-led projects can generate significant negative impacts, and raises questions about the pressures on development agencies to charge ahead with projects, despite obvious potential for such impacts.

    A case of hantavirus pulmonary syndrome (HPS) was serologically confirmed in a critically ill patient in Santiago, Chile. The patient's clinical course had many similarities to that of other HPS patients in North and South America but was complicated by acute severe renal failure. The patient's history included self-reported urban and probable rural rodent exposure during travel in Bolivia. Comparison of a viral sequence from an acute-phase serum sample with other known hantaviruses showed that the hantavirus nucleic acid sequence from the patient was very similar to a virus recently isolated from rodents associated with HPS cases in Paraguay.

Los movimientos afro brasileños y las poblaciones indígenas de Brasil están luchando cada vez más contra la discriminación, desarrollando sus propias identidades culturales y desmitificando el mito de la democracia racial brasileña. Algo similar está sucediendo en Perú y Bolivia donde las poblaciones indígenas están desafiando la vieja idea de la integración a través de la asimilación y el mestizaje, y los bolivianos han elegido su primer presidente indígena. Este proceso forma parte de estrategias multiculturales recientes. La asimilación a través del mestizaje fue la solución que funcionó, al menos aparentemente, en la mayoría de los países latinoamericanos desde la construcción de los Estado-Nación. El aspecto positivo de esta solución fue la construcción de una relación interétnica pacífica, pero su lado negativo ha sido que los grupos étnicos fueran aceptados sólo parcialmente y no se reconociera suficientemente la discriminación cultural a la que fueron sometidos Abstract The objective of this article is to analyze the different strategies of cultural resistance developed by groups ethnically discriminated in Brazil, Peru and Bolivia.

  19. Tenure Security and Land Appropriation under Changing Environmental Governance in Lowland Bolivia and Pará

    Directory of Open Access Journals (Sweden)

    Pablo Pacheco

    2015-02-01

    Full Text Available Appropriation of public lands associated with agricultural frontier expansion is a longstanding occurrence in the Amazon that has resulted in a highly skewed land-tenure structure in spite of recent state efforts to recognize tenure rights of indigenous people and smallholders living in or nearby forests. Growing concerns to reduce environmental impacts from agricultural development have motivated state governments to place greater attention on sustainable land management and forest conservation. This paper assesses the political and institutional conditions shaping tenure security and land appropriation in lowland Bolivia and the State of Pará in Brazil, and their links with environmental governance. The two cases show that clarifying and securing tenure rights is considered as the cornerstone for improving environmental governance. Thus, much attention has been given to the recognition of indigenous people and smallholder rights and to legalization of large-scale estates in agricultural frontiers, which have in turn influenced emerging conservation and environmental governance approaches. While policy frameworks share similar goals in the two cases, contrasting implementation approaches have been adopted: more agrarian in lowland Bolivia and more conservationist in the State of Pará.

    Background Acute respiratory infections represent a serious public health issue worldwide but virological aetiologies of Influenza Like Illnesses (ILIs) remain largely unknown in developing countries. This study represents the first attempt to characterise viral aetiologies of ILIs in Bolivia. Methods It was performed in Santa Cruz city from January 2010 to September 2012, based on 564 naso-pharyngeal swabs collected in a National Reference Laboratory and real-time PCR techniques, viral cultures and phylogenetic analyses. Results 50.2% of samples were positive for at least one virus with influenza viruses (Flu A: ~15%; Flu B: ~9%), rhinoviruses (~8%), coronaviruses (~5%) and hRSV (~4%) being the most frequently identified. The pattern of viral infections varied according to age groups. The elucidation rate was the highest (>60%) amongst patients under 10 yo and the lowest (ILIs in Bolivia to further inform the preparation of vaccines used in the region, guide vaccination campaigns and improve the medical management of patients.

    Summary Objectives Rotavirus is the most important etiology of severe diarrhea in Bolivia. The monovalent attenuated human oral rotavirus vaccine Rotarix® was introduced in Bolivia in 2008. We describe the molecular epidemiology of circulating rotavirus strains before vaccine introduction. Methods Two thousand one hundred thirty-five diarrheal samples were collected from hospitals in four Bolivian cities during 2007–2008. Forty-three percent (445 of 1030 rotavirus-positive samples) were analyzed for G and P genotypes. Among those, 331 were electropherotyped by polyacrylamide gel electrophoresis. Disease severity was quantified using a modified Vesikari scale. Results Among the 445 samples, five genotypes were found to be prevalent: G9P[8] (33%), G1P[6] (17%), G2P[4] (13%), G9P[6] (12%), and G1P[8] (4%). Co-infections with two or more strains accounted for 14% of samples. The most prevalent strain, G9, showed greater electropherotype diversity compared to other serogroups. Strain G1P[6] generally infected younger children and peaked later in the year than other strains. No particular genotype was associated with a higher severity score, though there was a significant difference in the duration of diarrhea between genotypes. Conclusions During the 2-year pre-vaccine period, substantial diversity of rotavirus co-circulating strains was observed. These data constitute a baseline against which changes in circulating strains post-vaccine introduction can be monitored. PMID:23688547

  3. Traditional llama husbandry and breeding management in the Ayopaya region, Bolivia.

    2010-01-01

    The llama claims the largest population of the domestic South American camelids, most of which are raised in Bolivia. More than 53,000 rural families are dedicated to llama husbandry as part of their livelihood strategy. Contemporary Andean societies deliberately select animals for specific traits and employ substantial livestock management to secure subsistence. This study presents traditional llama husbandry and breeding management activities in the Ayopaya region, Bolivia. Traditional selection traits for male and female llamas are documented and assessed by a ranking and a ratio-scaled evaluation. Husbandry and management parameters are in concordance with other studies conducted in the region, but show a high variation. Average llama herd sizes are rather small (mu = 45.6). In some herds, breeding males are utilized for a long time and mix with other herds, causing concerns about inbreeding. Preferred trait groups for llama males according to farmers' responses were body conformation, fibre, testicle conformation, fleece colour and height at withers. Traditional selection criteria generally relate to the phenotype, but also include the commercially interesting fibre trait. The presented results should be considered in breeding and management programmes for the respective llama population to ensure sustainable use of this genetically and culturally valuable resource.

    2003-07-01

    A new ice core record from the Nevado Illimani (16°S), Bolivia, covers approximately the last 18 000 years BP. A comparison with two published ice records, from Sajama (18°S), Bolivia [Thompson et al., Science 282 (1998) 1858-1864] and Huascarán (9°S), Peru [Thompson et al., Science 269 (1996) 46-50], documents a regionally coherent transition from glacial to modern climate conditions in South America north of 20°S. The strong resemblance between the Illimani and Huascarán water isotope records and their differences from the Sajama record, in particular during the period from 9000 years BP to 14 000 years BP, suggest that local water recycling or local circulation changes played a major role for Sajama. We interpret the common Illimani/Huascarán water isotope history in terms of a common change from wetter/cooler conditions during glacial times to drier/warmer conditions in the Early Holocene.

  5. Fascioliasis of livestock and snail host for Fasciola in the Altiplano Region of Bolivia.

    1975-01-01

    Fascioliasis caused by Fasciola hepatica was a serious problem for sheep and alpacas in the Altiplano Region of Bolivia. In some provinces close to Lake Titicaca, the raising of sheep was forced to discontinue, because infection with the fluke made it unprofitable and almost impossible. It was proved that in the Altiplano Region, two species of freshwater snails, Lymnaea viatrix and L. cubensis var., served as intermediate hosts for F. hepatica. In some subtropical areas of Bolivia, these snails could not be found, although other Lymnaea sp. was widely distributed there. As it is possible for Lymnaea sp. to be intermediate host for the fluke, further studies are required on the identification. Acute fascioliasis of sheep occurred in the Altiplano Region principally during a period from May to July, or the dry season. In some areas, the mortality rate of infected sheep was roughly estimated as 15 to 25% annually. Contamination with Fasciola metacercariae of herbage and semi-aquatic plants grown in a swamp in one of these areas was biologically assessed, using guinea pigs. Plants of Compositae and Eleocharis sp. were contaminated most intensely and those of Senicio sp. and Vallisneria sp. carried a fairly large number of cysts, while plants of Scirpus sp. and Ranunclaceae carried only a few cysts. No signs of Fasciola infection were observed in any animal given the plants of Liliaceae.

  6. Chapare virus, a newly discovered arenavirus isolated from a fatal hemorrhagic fever case in Bolivia.

    Simon Delgado

    2008-04-01

    Full Text Available A small focus of hemorrhagic fever (HF cases occurred near Cochabamba, Bolivia, in December 2003 and January 2004. Specimens were available from only one fatal case, which had a clinical course that included fever, headache, arthralgia, myalgia, and vomiting with subsequent deterioration and multiple hemorrhagic signs. A non-cytopathic virus was isolated from two of the patient serum samples, and identified as an arenavirus by IFA staining with a rabbit polyvalent antiserum raised against South American arenaviruses known to be associated with HF (Guanarito, Machupo, and Sabiá. RT-PCR analysis and subsequent analysis of the complete virus S and L RNA segment sequences identified the virus as a member of the New World Clade B arenaviruses, which includes all the pathogenic South American arenaviruses. The virus was shown to be most closely related to Sabiá virus, but with 26% and 30% nucleotide difference in the S and L segments, and 26%, 28%, 15% and 22% amino acid differences for the L, Z, N, and GP proteins, respectively, indicating the virus represents a newly discovered arenavirus, for which we propose the name Chapare virus. In conclusion, two different arenaviruses, Machupo and Chapare, can be associated with severe HF cases in Bolivia.

  7. Deformation, deposition, and surface uplift in the hinterland of the Central Andes, Bolivia

    Paleoelevation histories from mountain belts like the Central Andes of Bolivia provide important constraints on the timing and geodynamic mechanisms associated with surface uplift. New stable isotope data from paleosol carbonate nodules in the Altiplano and Eastern Cordillera of the Central Andes of Bolivia indicate a previously undocumented episode of surface uplift occurred in the region between ca. 24 and 17 Ma. Oxygen isotope and clumped-isotope thermometry values from paleosol carbonate in strata >24 Ma suggest paleoelevations as low as sea-level. Paleosol carbonate in strata ca. 17 Ma have oxygen isotope and clumped-isotope thermometry values, which using modern lapse rates, indicate an increase in elevation of approximately 3 km. Relatively undeformed Oligocene and Miocene strata overlap faulted Paleozoic rocks of the Bolivian Eastern Cordillera, indicating deposition and surface uplift post-dated and was decoupled from upper crustal deformation. Together, geological data from the area record an initial period of deformation and exhumation, a subsequent period of sediment deposition and overlap, and then an episode of surface uplift that was not accompanied by upper crustal deformation. We propose accommodation for the Oligocene-Miocene strata was associated with mantle and lowermost crustal processes, and the subsequent increase in surface elevation was an isostatic response to removal of dense material through delamination or drip. Combined with existing data sets in the Central Andes, these new data suggest multiple, regionally-variable, and diachronous periods of surface uplift occurred within the Central Andes during the Cenozoic Era.

    Microbial and geophysical surveys in the jungles of Bolivia's extensive Sub-Andean region have combined for three successful predictions of deep oil and gas reserves in as many tries. Hydrocarbon microseepage measured by microbial soil samples predicted the Carrasco, Katari, and Surubi structures of Bolivia's Chapare region in 1991--92, detecting traps with reserves at depths exceeding 4,500 m. Approximately 800 km of seismic lines covering 3,500 sq km was completed by Yacimientos Petroliferos Fiscales Bolivianos (YPFB) for evaluation of the YPFB reserve block. For 1 month each year at the end of the field season, seismic lines were quickly traversed by several microbial sampling teams. Using hand augers or shovels, the teams collected more than 3,200 samples approximately 20 cm (8 in.) deep at intervals of 250 m next to staked seismic locations. Microbial results were directly compared with seismic profiles for identification and ranking of traps and structures. The paper discusses the survey predictions and the microbial approach.

    The effectiveness of rotavirus vaccine in the field may set the stage for a changing landscape of diarrheal illness affecting children worldwide. Norovirus and rotavirus are the two major viral enteropathogens of childhood. This study describes the prevalence of norovirus and rotavirus 2 years after widespread rotavirus vaccination in Cochabamba, Bolivia. Stool samples from hospitalized children with acute gastroenteritis (AGE) and outpatients aged 5-24 months without AGE were recruited from an urban hospital serving Bolivia's third largest city. Both viruses were genotyped, and norovirus GII.4 was further sequenced. Norovirus was found much more frequently than rotavirus. Norovirus was detected in 69/201 (34.3%) of specimens from children with AGE and 13/71 (18.3%) of those without diarrhea. Rotavirus was detected in 38/201 (18.9%) of diarrheal specimens and 3/71 (4.2%) of non-diarrheal specimens. Norovirus GII was identified in 97.8% of norovirus-positive samples; GII.4 was the most common genotype (71.4% of typed specimens). Rotavirus G3P[8] was the most prevalent rotavirus genotype (44.0% of typed specimens) and G2P[4] was second most prevalent (16.0% of typed specimens). This community is likely part of a trend toward norovirus predominance over rotavirus in children after widespread vaccination against rotavirus.

    Full Text Available Este trabajo trata un tema relevante en la historiografía latinoamericana como es la expropiación petrolera mexicana durante el gobierno de Lázaro Cárdenas y aporta información original así como un enfoque innovador que desborda las historiografías estrictamente nacionales, intentando contribuir tanto a la historia de Bolivia como a la mexicana. La expropiación mexicana de 1938 alcanzó una dimensión trasnacional más allá de sus repercusiones diplomáticas: una experiencia percibida bajo muy diversos prismas en cada país latinoamericano. ¿Cómo fue vista la expropiación mexicana en los Andes bolivianos? Se argumenta que en la Paz, y en Sucre, diversos sectores de la sociedad leyeron esa expropiación tras los filtros del conflicto con la Standard Oil of Bolivia y del debate ideológico y político en torno a la recién creada YPFB, y cargaron de otro significado este episodio nacionalista al adaptarlo al contexto boliviano, dialogando simultáneamente con el sustrato previo de recepción de la revolución mexicana en la región, así como con el especial contexto político, económico y diplomático andino. Razones de orden nacional e internacional explican las reacciones ante el episodio petrolero mexicano en Bolivia, tanto como la percepción de estas por parte de la diplomacia mexicana.This article deals with a relevant subject in Latin American historiography, that being the Mexican oil expropriation during the Lázaro Cárdenas government and provides original information as well as an innovative approach that goes beyond strictly national historiographies, with the intention of contributing both to Bolivian and Mexican history.

How was the Mexican expropriation viewed in the Bolivian Andes? We have argued that in La Paz and Sucre, various

Studies associated with this research served as the basis for the implementation of health programs run by The Global Fund, The Pan-American Health Organization, International Cooperation, Non-Governmental Organizations and the Bolivian Ministry of Health and Sports. An analysis of the methodological contradictions and weaknesses was made by reviewing the bibliography of the studies and by conducting qualitative methodological research, that was focused on the quality of health care available to people living with HIV/AIDS in public hospitals and health centers, and looked at how programs targeted at this sector of the population are designed and delivered. In this manner, it was possible to observe the shortcomings of the methodological design in the

  2. Genetic characterization of Venezuelan equine encephalitis virus from Bolivia, Ecuador and Peru: identification of a new subtype ID lineage.

    Patricia V Aguilar

    Full Text Available Venezuelan equine encephalitis virus (VEEV has been responsible for hundreds of thousands of human and equine cases of severe disease in the Americas. A passive surveillance study was conducted in Peru, Bolivia and Ecuador to determine the arboviral etiology of febrile illness. Patients with suspected viral-associated, acute, undifferentiated febrile illness of <7 days duration were enrolled in the study and blood samples were obtained from each patient and assayed by virus isolation. Demographic and clinical information from each patient was also obtained at the time of voluntary enrollment. In 2005-2007, cases of Venezuelan equine encephalitis (VEE were diagnosed for the first time in residents of Bolivia; the patients did not report traveling, suggesting endemic circulation of VEEV in Bolivia. In 2001 and 2003, VEE cases were also identified in Ecuador. Since 1993, VEEV has been continuously isolated from patients in Loreto, Peru, and more recently (2005, in Madre de Dios, Peru. We performed phylogenetic analyses with VEEV from Bolivia, Ecuador and Peru and compared their relationships to strains from other parts of South America. We found that VEEV subtype ID Panama/Peru genotype is the predominant one circulating in Peru. We also demonstrated that VEEV subtype ID strains circulating in Ecuador belong to the Colombia/Venezuela genotype and VEEV from Madre de Dios, Peru and Cochabamba, Bolivia belong to a new ID genotype. In summary, we identified a new major lineage of enzootic VEEV subtype ID, information that could aid in the understanding of the emergence and evolution of VEEV in South America.

    Tailings from mining activities in Bolivia represent an environmental problem. In the vicinity of the tin mines of Llallagua, Potosi department, there are large dumps and tailings. We present a study of the use of these wastes as raw materials for the manufacture of glass. This procedure aims to contribute to environmental remediation of mining areas through the vitrification, a process which offers an alternative for stabilization of hazardous waste. In addition, the marketing of the obtained product would provide an additional income to the mining areas. For this study three samples of mining waste, with grain size between sand and silt, were used. The chemical composition of these raw materials, determined by X-ray fluorescence, is granitic, with high contents of heavy metals. On the basis of its composition, glass were made from silica glass by adding CaCO{sub 3} and Na{sub 2}CO{sub 3}. The thermal cycle has been determined from TDA. Tg values of glass range from 626 degree centigrade to 709 degree centigrade. Leaching tests of the obtained glasses confirm their capacity to retain heavy metals. (Author) 38 refs.

Con este eje compite otro por el Sur, sede de los principales asientos mineros y gasíferos, y otro de menos potencial por el Norte. El análisis comparativo resalta las diferentes perspectivas de cada una de las tres principales zonas y la naturaleza diferenciada de los procesos urbanos y regionales, así como las direcciones posibles y los ritmos del cambio urbano-ruralClose to the creation of departmental autonomies and the celebration of an Asamblea Constituyente in June of 2006, metropolitan areas become the main cores of economic development in Bolivia. This paper analyzes the rapid way in which Bolivia has moved from a rural country to an urban one, around a central axis that will gather almost three quarters of the total population (mainly of indigenous origin within a few decades, as well as the demands for services and labor market. From the South, where the main mining and gas settlements are located, another axis competes with this one, as well as another one from the North, but with less potential. The comparative analysis remarks the different perspectives of each zone, the differentiated nature of urban and regional processes and the possible courses and rhythms of the rural-urban change

    Full Text Available This article considers ‘kirchnerism’ and ‘evism’ to be popular identity movements which have attempted to provide answers to the open social dislocations since the crisis of December 2001 in Argentina, and the cycle of protests from 2000-2005 in Bolivia. The emergence of both of these identity constructions has involved at least three simultaneous processes. Firstly, the gradual incorporation of public decision-making on subjects and demands which were formerly ignored; secondly, political divisions within communities; and, finally, establishing a nation within the new institutional framework currently in force. As these processes developed, some points of approach and distancing between the case studies were noted.

  7. Blaming Machismo: How the Social Imaginary is Failing Men with HIV in Santa Cruz, Bolivia.

    Science.gov (United States)

    Heckert, Carina

    2017-01-01

    Drawing from an ethnography of HIV care in Santa Cruz, Bolivia, in this article I explore how the social imaginary surrounding gender relations shapes men's experiences of seeking care for and living with HIV. Popular understandings of gender relations, which draw heavily on the machismo concept, intersect with a global health master narrative that frames women as victims in the AIDS epidemic in a way that generates a strong sentiment of blaming machismo within local HIV/AIDS-related services. Statements such as, "it's because of machismo" are used to explain away epidemiological trends. Participant observation in the context of HIV care, coupled with illness narrative interviews, illuminate how blaming machismo shapes men's experiences of care and the ways that they feel excluded from various forms of support. Thus, the illness experiences of men with HIV problematize the machismo concept and how it is drawn upon in the context of care.

    Data on the distribution and abundance of Lutzomyia spp. (Diptera: Psychodidae) in Bolivia is scarce. Sand flies from an area of Leishmania (Viannia) braziliensis endemicity in the Isiboro-Secure National Park in the Department of Cochabamba were captured and identified to species. In total, 945 sand flies (789 females and 156 males) belonging to 15 species were collected from the four collection points in two study villages in 2007. With 549 (58.1%) specimens, Lutzomyia shawi was the most abundant species, followed by Lutzomyia (Trichophoromyia) sp. (22.2%), Lutzomyia llanosmartinsi (8.3%), Lutzomyia antunesi (4.3%), and Lutzomyia olmeca (2.1%). Abundance and species composition varied between rainy and dry seasons, with 99.3% of all sand flies being collected outdoors. Because of species abundance and confirmed Leishmania infection in previous entomological collections, we believe Lu. shawi is the vector of L. (Viannia) braziliensis in Isiboro-Secure National Park.

    2013-03-01

    Full Text Available Upon his presidential election, Bolivian coca grower leader Evo Morales adopted a policy of promoting consensual coca reduction through social control, a sophisticated coca monitoring system, and economic development. That strategy is paying off. In 2011, coca cultivation decreased by 13 per cent according to the U.S. government. The Morales administration has also made significant progress facing the ongoing challenges of drug production and trafficking. Seizures of coca paste and cocaine and destruction of drug laboratories have steadily increased since President Morales took office. Despite continued tensions in bilateral relations, U.S.-Bolivian counter-drug cooperation continues and the signing of a new framework agreement in 2011 should lead to an exchange of ambassadors. Internationally, Bolivia has successfully gained acceptance of the right to the traditional use of coca within its own territory. But Bolivia’s efforts must be carried out in tandem with effective demand reduction strategies to shrink the global cocaine market.

As a result, faced with the serious reality of unemployment and the precariousness of the Spanish labour market, the option of return has become the last resort for some immigrants, and an attractive strategy for governments (of both countries of origin and destination, which attempt to manage return using special programmes. From this point of view, the aim of this paper is to examine the assisted voluntary return programmes in Spain and Bolivia and their suitability to the dynamics of return, beginning with an exhaustive review of the programmes and the perceptions on them expressed by Bolivian immigrants as part of the survey «Circulation and Return», carried out within the framework of the RETTRANS project.

    A randomised controlled field trial was conducted to evaluate the effectiveness of ceramic drip filters to improve the microbiological quality of drinking water in a low-income community in rural Bolivia. In four rounds of water sampling over five months, 100% of the samples were free of thermotolerant (faecal) coliforms (TTC) compared to an arithmetic mean TTC count of 1517, 406, 167 and 245 among control households which continued to use their customary sources of drinking water. The filter systems produced water that consistently met WHO drinking-water standards despite levels of turbidity that presented a challenge to other low-cost POU treatment methods. The filter systems also demonstrated an ability to maintain the high quality of the treated water against subsequent re-contamination in the home.

    In 2003 a pilot study was carried out in the rural area of the Bolivian Department of La Paz aiming at the identification of dietary patterns among a group of secondary school adolescents who have little or scarce contact with the urban centres. The study consisted of a food intake survey (24 h recall), the measurement of anthropometrics and sociodemographic information. Nine percent was the global prevalence of overweight, although it was more present in girls. No statistically significant differences were found between nutrients in the diets of boys and girls. The energy intake was distributed in the five usual eating times as follows: 22% breakfast, 20% break time at school, 24% lunch, 12% tea time and 22% dinner. Furthermore, the anthropometric measures of boys were compared with their urban counterparts, where the differences were only significant with students in private schools. The present study can be used for the formulation of nutritional policies in Bolivia.

Even though, in the last twenty years, on both countries some Indian alternative project educational programs have been raised, they have important differences, which are shown, not only in their legislation but also in their policies and programs. The essence of these differences may be found in their own legislation, which states a “national, democratic, intercultural and bilingual education” for all Bolivian and an Indian population exclusive education in the Mexican care.

  20. Personal and political histories in the designing of health reform policy in Bolivia.

    2017-03-01

    While health policies are a major focus in disciplines such as public health and public policy, there is a dearth of work on the histories, social contexts, and personalities behind the development of these policies. This article takes an anthropological approach to the study of a health policy's origins, based on ethnographic research conducted in Bolivia between 2010 and 2012. Bolivia began a process of health care reform in 2006, following the election of Evo Morales Ayma, the country's first indigenous president, and leader of the Movement Toward Socialism (Movimiento al Socialism). Brought into power through the momentum of indigenous social movements, the MAS government platform addressed racism, colonialism, and human rights in a number of major reforms, with a focus on cultural identity and indigeneity. One of the MAS's projects was the design of a new national health policy in 2008 called The Family Community Intercultural Health Policy (Salud Familiar Comunitaria Intercultural). This policy aimed to address major health inequities through primary care in a country that is over 60% indigenous. Methods used were interviews with Bolivian policymakers and other stakeholders, participant observation at health policy conferences and in rural community health programs that served as models for aspects of the policy, and document analysis to identify core premises and ideological areas. I argue that health policies are historical both in their relationship to national contexts and events on a timeline, but also because of the ways they intertwine with participants' personal histories, theoretical frameworks, and reflections on national historical events. By studying the Bolivian policymaking process, and particularly those who helped design the policy, it is possible to understand how and why particular progressive ideas were able to translate into policy. More broadly, this work also suggests how a uniquely anthropological approach to the study of health policy

    Full Text Available Abstract Background Molecular epidemiological studies of HIV-1 in South America have revealed the occurrence of subtypes B, F1 and BF1 recombinants. Even so, little information concerning the HIV-1 molecular epidemiology in Bolivia is available. In this study we performed phylogenetic analyses from samples collected in Bolivia at two different points in time over a 10 year span. We analyzed these samples to estimate the trends in the HIV subtype and recombinant forms over time. Materials and methods Fifty one HIV-1 positive samples were collected in Bolivia over two distinct periods (1996 and 2005. These samples were genetically characterized based on partial pol protease/reverse transcriptase (pr/rt and env regions. Alignment and neighbor-joining (NJ phylogenetic analyses were established from partial env (n = 37 and all pol sequences using Mega 4. The remaining 14 env sequences from 1996 were previously characterized based on HMA-env (Heteroduplex mobility assay. The Simplot v.3.5.1 program was used to verify intragenic recombination, and SplitsTree 4.0 was employed to confirm the phylogenetic relationship of the BF1 recombinant samples. Results Phylogenetic analysis of both env and pol regions confirmed the predominance of "pure" subtype B (72.5% samples circulating in Bolivia and revealed a high prevalence of BF1 genotypes (27.5%. Eleven out of 14 BF1 recombinants displayed a mosaic structure identical or similar to that described for the CRF12_BF variant, one sample was classified as CRF17_BF, and two others were F1pol/Benv. No "pure" HIV-1 subtype F1 or B" variant of subtype B was detected in the present study. Of note, samples characterized as CRF12_BF-related were depicted only in 2005. Conclusion HIV-1 genetic diversity in Bolivia is mostly driven by subtype B followed by BF1 recombinant strains from the CRF12_BF "family". No significant temporal changes were detected between the mid-1990s and the mid-2000s for subtype B (76.2% vs 70

    The Bolivia-Brazil Natural Gas Pipeline starts at Santa Cruz de La Sierra city, in Bolivia, and goes until Canoas City (RS) in Brazil, with a total extent of 3,150 km. The pipeline crosses in the 2,593 km established in Brazilian soil, the most diverse types of geology and geomorphology. Along the line, the right-of-way (ROW) also crosses a lot of roads, railways, rivers and lakes. During a routine inspection (foot patrol), signs of instability were detected at an embankment slope of a highway of the Santa Catarina state, at the pipeline crossing. An eventual failure of this slope could put the pipeline at risk. The aim of this paper is to present the aspects of the stabilizations phases, since field investigation, design, works, instrumentation, until monitoring. Emphasis is given to the design criteria to pipeline safety. The solution adopted is composite by soil nailing, a changing of slope inclination and superficial drainage system. (author)

    Full Text Available During the first decade of the 2000s, Bolivia occasionally turned violent. Yet the causes of these episodes of sustained violence have not yet been identified. To this end, this article tests which mechanisms theorized by existing scholarship produced two prolonged episodes of violence. It concludes that both episodes emerged from the same causal pathway: the national government provoked violence by seeking to raze the economic foundations of well-organized sectors – sectors that represented the mass bases of ascendant political oppositions. This finding not only sheds light on political order in Bolivia, but also opens up new directions in research on violent confrontation in Latin America.Durante la primera década de los 2000, Bolivia se tornó violenta de vez en cuando. Sin embargo, las causas de estos episodios aun no se han identificado.

El ensayo concluye que ambos episodios emergieron a partir del mismo mecanismo: el gobierno nacional provocó la violencia con sus intentos de destruir los fundamentos económicos de sectores organizados – sectores que representaron las bases de oposiciones políticas emergentes. Este resultado no sólo nos enseña sobre el orden político en Bolivia, sino que abre nuevas direcciones en la investigación sobre la confrontación violenta en América Latina.

    Full Text Available Is it possible to justify resource extractivism to provide progressive welfare politics and still respect the constitutional rights of nature? The Indigenous concept of Sumak Kawsay on human beings living in harmony with each other and the environment is the fundamental framing of the new constitutions of Ecuador and Bolivia. These constitutional reforms embrace strengthened proper rights of nature and similarly of ethnic rights. However, the same constitutions grant the State the right to exploit and commercialize natural resources and extractivism has increased. This study revises the tensions between welfare politics, extractivism and the rights of nature and the Indigenous peoples in the new constitutional settings of Bolivia and, particularly, Ecuador. The article argues that Sumak Kawsay challenges dominating understandings of the concepts of welfare, common good and development, and likewise that a pragmatic approach is applied by national governments towards the constitutional rights of nature amidst other human values.

    Full Text Available Bolivia is a high-endemic country for Chagas disease, for which the principal vector is Triatoma infestans (Triatominae. This is a mainly domestic species that is also found in the wild environment. Recently, an increasing number of studies have shown the importance of Triatominae resistance to insecticides, especially in Bolivia. Data regarding the susceptibility/resistance of wild and domestic populations of T. infestans to deltamethrin are presented. For the first time, domestic populations of the department of Santa Cruz were tested, showing low resistance. Although most of the wild populations were found to be susceptible to deltamethrin, three populations from three departments showed a mortality rate of less than 100%. This result is emphasised here.

    Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

    Coca-Erythroxylum coca Lamarck var. coca-remains one of the most common plants of the folk medicine of Bolivia used as a general stimulant. Aymara and Quechua natives prefer to chew the sweeter coca leaves from the Yungas (tropical mountain forests of the eastern slopes of the Andes) rather than those from the Chapare lowlands. The contents in cocaine and minor constituents of leaf samples cultivated in these regions does not rationalize this choice.

    Full Text Available El 18 de julio del 2004 se dio el primer referéndum sobre los hidrocarburos en Bolivia; el proceso pre-referéndum puso en manifiesto problemas nacionales que amenazaban la estabilidad social. Este trabajo analiza las posiciones de los sectores sociales organizados y de los partidos políticos más importantes de Bolivia, en una coyuntura política conflictiva donde las diferencias entre los distintos actores sociales y políticos imposibilitaban el establecimiento de una política hidrocarburífera consensuada desde el Ejecutivo. Del mismo modo estudia cómo estos hechos influyeron en las características de la iniciativa presidencial en la política de hidrocarburos. Finalmente, muestra que en su momento el referéndum sirvió para legitimar al Presidente Carlos Mesa, pero a la larga las discrepancias entre el poder legislativo y el poder ejecutivo en torno a la interpretación de los resultados del referéndum contribuyeron al debilitamiento del Presidente y a su posterior renuncia.The referendum of July 2004 in Bolivia over hydrocarbon policies in Bolivia disclosed many of the national problems that threatened social peace. This paper analyses the attitudes of different labor unions, political parties, and civic communities within the context of the referendum and how the stances of political and social actors in the referendum produced internal divisions. It also examines how these groups' different points of view on President Mesa's hydrocarbon policy contributed to the call for a referendum. The work demonstrates that for a short period of time the referendum served to legitimize Carlos Mesa's presidency but in a long run defeated of it own presidency.

    Post-abortion care (PAC), an innovation for treating women with complications of unsafe abortion, has been introduced in public health systems around the world since the 1994 International Conference on Population and Development (ICPD). This article analyzes the process of scaling-up two of the three key elements of the original PAC model: providing prompt clinical treatment to women with abortion complications and offering post-abortion contraceptive counseling and methods in Bolivia and Mexico. The conceptual framework developed from this comparative analysis includes the environmental context for PAC scale-up; the major influences on start-up, expansion, and institutionalization of PAC; and the health, financial, and social impacts of institutionalization. Start-up in both Bolivia and Mexico was facilitated by innovative leaders or catalyzers who were committed to introducing PAC services into public health care settings, collaboration between international organizations and public health institutions, and financial resources. Important processes for successful PAC expansion included strengthening political commitment to PAC services through research, advocacy, and partnerships; improving health system capacity through training, supervision, and development of service guidelines; and facilitating health system access to essential technologies. Institutionalization of PAC has been more successful in Bolivia than Mexico, as measured by a series of proposed indicators. The positive health and financial impacts of PAC institutionalization have been partially measured in Bolivia and Mexico. Other hypotheses--that scaling-up PAC will significantly reduce maternal mortality and morbidity, decrease abortion-related stigma, and prepare the way for efforts to reform restrictive abortion laws and policies--have yet to be tested.

    Full Text Available Here we report a superbly preserved and profusely represented five-ichnotaxa dinosaur track assemblage near Icla village, 100 km southeast of Sucre, Bolivia. As preserved in reddish Jurassic-Cretaceous boundary aeolian sandstones, this rich and uncommon assemblage is, additionally, the oldest dinosaur tracksite for Bolivia. Four trackmakers were identified in the area: three quadrupedal and one bipedal, all of them with tracks of around 35 cm in lenght. One of the quadrupedals is represented by no less than five adult individuals (ichnotaxon A, and four purported juveniles (ichnotaxon B walking in association. The other two quadrupedals (ichnotaxa C and D involve four trackways, and the last, the bipedal trackmaker (ichnotaxon E, is represented by one trackway. The five ichnotaxa represented in the "Palmar de Tunasniyoj" could be tentatively assigned to the following trackmakers: Ichnotaxa A and B are assigned to basal stegosaurians; ichnotaxon C to a basal tyreophoran, perhaps related to the ankylosaur lineage; ichnotaxon D to the Ankylosauria, and ichnotaxon E to Theropoda. The Tunasniyoj assemblage, the oldest dinosaur tracksite for Bolivia, includes the oldest known evidence assigned to ankylosaurs and stegosaurs for South America.Neste estudo é relatado um conjunto magnificamente preservado de pistas de dinossauros representados por cinco táxons distintos, situado próximo à Vila de Icla, 100 quilômetros a sudeste do Sucre, Bolívia.

  2. Imaging Lithospheric-scale Structure Beneath Northern Altiplano in Southern Peru and Northern Bolivia

    The northern Altiplano plateau of southern Peru and northern Bolivia is one of the highest topographic features on the Earth, flanked by Western and Eastern Cordillera along its margin. It has strongly influenced the local and far field lithospheric deformation since the early Miocene (Masek et al., 1994). Previous studies have emphasized the importance of both the crust and upper mantle in the evolution of Altiplano plateau (McQuarrie et al., 2005). Early tomographic and receiver function studies, south of 16° S, show significant variations in the crust and upper mantle properties in both perpendicular and along strike direction of the Altiplano plateau (Dorbath et. al., 1993; Myers et al., 1998; Beck and Zandt, 2002). In order to investigate the nature of subsurface lithospheric structure below the northern Altiplano, between 15-18° S, we have determined three-dimensional seismic tomography models for Vp and Vs using P and S-wave travel time data from two recently deployed local seismic networks of CAUGHT and PULSE. We also used data from 8 stations from the PERUSE network (PERU Subduction Experiment). Our preliminary tomographic models show a complex variation in the upper mantle velocity structure with depth, northwest and southeast of lake Titicaca. We see the following trend, at ~85 km depth, northwest of lake Titicaca: low Vp and Vs beneath the Western Cordillera, high Vs beneath the Altiplano and low Vp and Vs beneath the Eastern Cordillera. This low velocity anomaly, beneath Eastern Cordillera, seems to coincide with Kimsachata, a Holocene volcano in southern Peru. At depth greater than ~85 km: we find high velocity anomaly beneath the Western Cordillera and low Vs beneath the Altiplano. This high velocity anomaly, beneath Western Cordillera, coincides with the well-located Wadati-Benioff zone seismicity and perhaps represents the subducting Nazca slab. On the southeast of lake Titicaca, in northern Bolivia, we see a consistently high velocity anomaly

    This case study analyses current migration dynamics in two regions of Bolivia: Northern Potosi, one of the main areas of outmigration in Bolivia, and the municipality of San Julian in the Department of Santa Cruz, a major destination for internal migrants, some of whom come from Northern Potosi. The research was qualitative in nature, with specific attention to breadth and accuracy in the information and analysis. The methods used were participative and the research was done in collaboration with the rural and indigenous organisations in the two selected areas: the Federation of Indigenous Ayllus of Northern Potosi (Federacion de Ayllus Originarios Indigenas del Norte de Potosi Charka Qhara Qhara - FAOI-NP) and the Federation of Intercultural Communities of San Julian (Federacion de Comunidades Interculturales de San Julian). The information gathering process examined a wide range of factors that may trigger migration, including the possible influence of climate change and public policies on migration. The key challenge was to understand current patterns of migration, the processes involved and the social, cultural, economic and political causes and effects, taking into account issues that are increasing in importance, such as climate change, and seeking to discover the extent of their influence in the midst of other factors that drive migration. It is well known that migration is not a simple occurrence. In fact, it involves a series of processes, motivations, causes and decisions. Because it is a collective rather than an individual process, it takes on the character of a 'social phenomenon' that is historically and geographically determined. In many cases, there are cultural practices of transhumance, such as agriculture on different ecological levels or the use of winter and summer pastures. This involves people moving from one place to another, sometimes travelling long distances and crossing districts for several months at a time. These transhumance

    Recent insights shed light on the global mechanisms involved in the abrupt oscillations of the Earth climate for the Late Glacial Maximum (LGM) to Holocene period (Zhang et al., 2014; Banderas et al., 2015). Yet the concomitant patterns of regional climate reorganization on continental areas are for now poorly documented. Particularly, few attempts have been made to propose temporal reconstructions of the regional climate variables in the High Tropical Andes, a region under the direct influence of the upper part of the troposphere. We present new glacial chronologies from the Zongo (16.3°S - 68.1°W, Bolivia) and Wara-Wara (17.3°S - 66.1°W, Bolivia) valleys based on Cosmic Ray Exposure dating (CRE) from an exceptional suite of recessive moraines. These new data permitted to refine existing chronologies (Smith et al., 2005 ; Zech et al., 2010): the Zongo valley is characterized by an older local last glacial maximum than the Wara Wara valley. Both sites however exhibit similar glacier behaviours, with a progressive regression between 18 ka and the Holocene. In both sites, glaciers recorded stillstand episodes synchronous with the cold events of the Norther Hemisphere (Henrich 1 event, Younger Dryas). Since the nearby Altiplano basin registered lake level variations over the same period, we were able to apply a joint modelling of glaciers Equilibrium Line Altitude (ELA) and lake budget. This permits to derive a temporal evolution of temperature and precipitation for both sites. These new reconstructions show for both sites that glaciers of the Eastern Tropical Andes were both influenced by the major climatic events of the Northern and Southern Hemispheres. However, precipitation variability is more influenced by the Northern Atlantic events. This observation is in good agreement with the theories suggesting that North Hemisphere cold events are coeval with an important southward deflexion of the Intertropical Convergence Zone (ITCZ) due to the inter

    Full Text Available RESUMEN: Bolivia celebró en 2005 una elección presidencial anticipada que constituyó la respuesta a la grave crisis política y social que vivió el país en los años previos. El resultado de los comicios no tuvo precedentes en la historia democrática reciente pues por primera vez un candidato consiguió la mayoría absoluta y los partidos hasta entonces dominantes quedaron en una posición desairada. El triunfador, Evo Morales, encabezó una organización de izquierda que criticó con dureza el liberalismo económico, reivindicó el nacionalismo, prometió una reforma profunda de la política e hizo énfasis en la identidad étnica indígena. Superó por amplio margen al ex presidente Jorge Quiroga y conformó el primer gobierno monocolor desde el retorno a la democracia. El artículo busca ofrecer una explicación política y sociológica de los principales datos de la elección, interesándose en el desarrollo de la campaña y el comportamiento de los votantes.ABSTRACT: Bolivia celebrated in 2005 a presidential early election that constituted the response to the serious political and social crisis that lived through the country in the previous years. The result of the assemblies did not have precedents in the democratic recent history since for the first time a candidate obtained the absolute majority and the parties till then dominant stayed in a graceless position. The winner, Evo Morales, headed an organization of left side that criticized with hardness the economic liberalism, claimed the economic nationalism, promised a deep reform of the politics and did emphasis in the ethnic indigenous identity. He overcame for wide margin the ex-president Jorge Quiroga and the first government shaped monocolor from the return to the democracy. The article seeks to offer a political and sociological explanation of the principal information of the election, being interested in the development of the campaign and the behavior of the voters.

    Full Text Available Este trabajo sitúa el problema de la guerra del Acre en un contexto multilateral, reconociendo la vigencia del equilibrio de poder como parte del razonamiento de la conducción de las políticas exteriores en juego. Se aplica el concepto de frontera de F. J. Turner, para explicar cómo las fronteras permeables pusieron a Brasil y Bolivia en confrontación, por la maniobra boliviana de configurar una concesión a inversionistas estadounidenses, británicos y franceses, que fue interpretada por Brasil como una maniobra imperialista de Estados Unidos. Entones Brasil se acercó a Chile, y afrontaron juntos los problemas del Acre y de Antofagasta, que derivaron en las redacciones de los tratados de Petrópolis (1903 y de Paz y Amistad (1904. El artículo postula que Bolivia procedió de esta forma para impedir el avance brasileño, peruano y paraguayo sobre sus fronteras, y que la búsqueda del paraguas estadounidense fue una idea que Bolivia gestó para compensar el desequilibrio de poder.This work considers the Acre War as part of a multilateral context where the equilibrium of power was important in the reasoning behind the establishment of foreign relations. It uses the frontier concept developed by F. J. Turner to explain why their open frontier put Brazil and Bolivia in confrontation. This happened because of the Bolivian strategy of granting land to investors from the United States, Great Britain and France, which was interpreted by Brazil as an imperialist action promoted by the United States. This explains why Brazil established a cióse relationship with Chile to confront together their problems in Acre and Antofagasta, which led to the drafting of the Petrópilis (1903 and Paz y Amistad (1904 treaties. The article argues that Bolivia proceeded this way to avoid a Brazilian, Peruvian or Paraguayan territorial advance, seeking the support of the United States to compénsate the imbalance of power.

  9. Polygyny among the Tsimane of Bolivia: an improved method for testing the polygyny-fertility hypothesis.

    The polygyny-fertility hypothesis states that polygyny is associated with reduced fertility for women and is supported by a large body of literature. This finding is important, because theoretical models of polygyny often differentiate systems based on the degree to which women are forced or willingly choose to enter polygynous marriages. The fact that polygyny tends to be associated with reduced fertility has been presented as evidence that polygyny is often less favourable for women, and that women must, therefore, be pressured into accepting such arrangements. Previous studies, however, have been hampered by the non-random assignment of women into monogamous and polygynous unions (i.e. self-selection), as differences between these groups of women might explain some of the effects. Furthermore, the vast majority of such studies focus on sub-Saharan populations. We address these problems in our analysis of women's fertility in polygynous marriages among the Tsimane of Bolivia. We offer a more robust method for assessing the impact of polygynous marriage on reproductive outcomes by testing for intra-individual fertility effects among first wives as they transition from monogamous to polygynous marriage. We report a significant link between polygyny and reduced fertility when including all cases of polygyny; however, this association disappears when testing only for intra-individual effects.

    Full Text Available El año de 1998 se recuerda por una crisis económica mundial que golpeó muy fuerte a Bolivia y socavó las bases económicas de la estabilidad política sobre la que se apoyó el neoliberalismo desde el año de 1986. El gobierno pretendió hacer pagar la crisis a los sectores populares, lo que desencadenó “el ciclo rebelde”, que derrotó primero en el 2000 la privatización trasnacional del agua, cercó las grandes ciudades varias veces en defensa de los sembrados de coca durante el primer lustro del siglo y reapropió para el Estado el servicio de gas en el año 2003. Al fragor de las luchas se construyó “la agenda de octubre”, que participó del conjunto de condiciones políticas necesarias para que las revueltas sociales se convirtieran en alternativa de poder, programa que llevaría a la victoria electoral de la presidencia de la república al indígena Evo Morales a finales del 2005.

    Full Text Available In the last five years, Bolivia has been experiencing legal and institutional changes. A new legal scenario is dawning for indigenous peoples, at least in theory. The participation of indigenous people in the constituent assembly was extremely high. Because of this participation, as well as the lobbying of their organizations (e.g., CIDOB, CONAMAQ, CSUTCB, their agenda was (partially included in the Magna Charta. In particular, a new complex system of autonomies, including the Autonomía Indígena Originaria Campesina (AIOC, has been introduced in the Bolivian constitutional order. Despite the initial enthusiasm after the creation of the first 11 municipality-based AIOCs in December 2009 and the enactment of the dense Autonomy Law in July 2010 (Ley Marco de Autonomías y Descentralización, Ley No. 031, there are still many pending issues, especially vis-à-vis formal requisites (e.g., the statutes. Hence, this article, after introducing some theoretical issues concerning the indigenous autonomies, analyses the development of the first municipality-based AIOCs, shedding some light on their complex legal framework.

    A two layer, nonlinear, equatorial beta-plane model, in p-coordinates is used to study the atmospheric response to a large scale prescribed heat source varying in time. The heat source is meant to represent a convective burst with total duration of approximately 48 hours over the Amazon/Bolivia region. The boundary conditions used are meridional velocity zero at 60 deg S, omega w = 0 at the top and zero geometric velocity at the lower boundary. Sensitivity study was done which includes initial state at rest, compared with realistic initial flow. The scale of the heat source is 1500 km in latitude and longitude and it is centered at 10 deg S. Special attention is paid to the distribution and intensity of the induced vertical motion. The model is integrated for two days and the preliminary results show agreement with the observed 200 mb flow. Of interest is the establishment of a trough and descending motion to the northeast of the heat source. A conjucture is thus made that the Amazon heat source and its fluctuations bear some relationship with the drought problem over Northeast Brazil.

  16. Four thousand years of environmental change and human activity in the Cochabamba Basin, Bolivia

    Williams, Joseph J.; Gosling, William D.; Coe, Angela L.; Brooks, Stephen J.; Gulliver, Pauline

    The Cochabamba Basin (Bolivia) is on the ancient road network connecting Andean and lowland areas. Little is known about the longevity of this trade route or how people responded to past environmental changes. The eastern end of the Cochabamba valley system constricts at the Vacas Lake District, constraining the road network and providing an ideal location in which to examine past human-environmental interactions. Multi-proxy analysis of sediment from Lake Challacaba has allowed a c. 4000 year environmental history to be reconstructed. Fluctuations in drought tolerant pollen taxa and calcium carbonate indicate two periods of reduced moisture availability ( c. 4000-3370 and c. 2190-1020 cal yr BP) compared to adjacent wetter episodes ( c. 3370-2190 and c. 1020 cal yr BP-present). The moisture fluctuations broadly correlate to El Niño/Southern Oscillation variations reported elsewhere. High charcoal abundance from c. 4000 to 2000 yr ago indicates continuous use of the ancient road network. A decline in charcoal and an increase in dung fungus ( Sporormiella) c. 1340 -1210 cal yr BP, suggests that cultural changes were a major factor in shaping the modern landscape. Despite undisputable impacts of human populations on the Polylepis woodlands today, we see no evidence of woodland clearance in the Challacaba record.

  17. The expansion of brown rot disease throughout Bolivia: possible role of climate change.

    Bacterial wilt is a devastating plant disease caused by the bacterial pathogen Ralstonia solanacearum species complex and affects different crops. Bacterial wilt infecting potato is also known as brown rot (BR) and is responsible for significant economic losses in potato production, especially in developing countries. In Bolivia, BR affects up to 75% of the potato crop in areas with high incidence and 100% of stored potatoes. The disease has disseminated since its introduction to the country in the mid-1980s mostly through contaminated seed tubers. To avoid this, local farmers multiply seed tubers in highlands because the strain infecting potatoes cannot survive near-freezing temperatures that are typical in the high mountains. Past disease surveys have shown an increase in seed tubers with latent infection in areas at altitudes lower than 3000 m a.s.l. Since global warming is increasing in the Andes Mountains, in this work, we explored the incidence of BR in areas at altitudes above 3000 m a.s.l. Results showed BR presence in the majority of these areas, suggesting a correlation between the increase in disease incidence and the increase in temperature and the number of irregular weather events resulting from climate change. However, it cannot be excluded that the increasing availability of latently infected seed tubers has boosted the spread of BR.

    The highly fossiliferous sediments of the Tolomosa Formation from Tarija, southern Bolivia, represent one of the most important localities in South America that documents the Great American Biotic Interchange. Over the past several decades, chronostratigraphic studies have indicated a middle Pleistocene age for the Tolomosa Formation from ~ 1.1 to 0.7 Ma. This interval correlates to the Ensenadan South American Land Mammal Age as it is characterized from classic localities in Argentina. Recently, however, a new interpretation based on AMS 14C ages indicates that the fossiliferous sediments from Tarija are latest Pleistocene, i.e., < 44 ka, and thus of Lujanian age. Here we report a new age of 0.76 ± 0.03 Ma (2σ) based on 11 U-Th/Pb and U-Th/He individual determinations from the Tolomosa Formation. This is indistinguishable from the age published from the same ash in 1983, and was originally used to calibrate the magnetostratigraphic section at Tarija. The new age confirms that the age of the Tolomosa Formation is middle Pleistocene, and not latest Pleistocene. The age of the Tarija Fauna has significant implications with regard to the stage of evolution biochronology for Pleistocene fossil mammals in South America, and in particular, the classic and important reference sections in Argentina.

    Full Text Available Background: Sigmoid volvulus is an emergency that occurs very frequently in the South American Andean area hospitals. It accounts for over 50% of all intestinal obstructions and still retains high mortality rates. Objective: To characterize the management of sigmoid volvulus. Methods: A prospective and descriptive study was conducted including all patients with sigmoid volvulus who attended three general community hospitals of the Cuban medical mission in Bolivia from June 2006 to June 2007 and were treated trough general surgery. We analyzed the following variables: age, sex, medical history, surgical diagnosis, classification and type of surgery, surgery performed, evolution, complications, use of antibiotic-prophylaxis and admission to intensive care units. The information was obtained from medical records, operative reports and a data collector model. Results: Sigmoid volvulus occurred more frequently in the Yapacaní hospital, department of Santa Cruz; the predominant age group was that from 55 to 64 years old as well as the predominant sex was that of males. Chagas disease was detected in most of the patients studied. Among symptoms those that predominated were distension, abdominal pain and stool detention. Decompression, devolvulation and surgical treatment were the processes followed in all cases, being the Rankin-Mikulicz colostomy the most widely used. No patients underwent a second surgery, and there were no mortality rates. Conclusions: Decompression, devolvulation and surgical treatment were the processes followed in all cases, being the Rankin-Mikulicz colostomy the most widely used. Most patients had a satisfactory evolution.

    Full Text Available This article argues that relations between social movements and organizations and the State are not only developed based on defended objectives and interests in political negotiations, but are also developed within particular situations, of specific cultures and histories. Our investigation about the relationship between mining cooperatives, their national organization, and the Bolivian State demonstrates the crucial importance of considering historical aspects, of collective memory, some regional and others within the organizations themselves. The traditions, memories, and abilities incorporated in the mining organizations and in the political realm will influence the way in which different parts relate to one another, design their strategies, and adapt to changing circumstances. This topic is illustrated firstly through a historical and contemporary account of mining in Bolivia focused in the sector of small scale mining. This is followed by outlining the position that cooperative mining occupies in the country and the strategies and self esteem that they display. Next, our case study is addressed: the ASOBAL cooperative. In the national outline, like in our case study, we connect the positions and strategieswith themes of identity, memory, and place.

  2. Hantavirus pulmonary syndrome in Santa Cruz, Bolivia: outbreak investigation and antibody prevalence study.

    Joel M Montgomery

    Full Text Available We report the results of an investigation of a small outbreak of hantavirus pulmonary syndrome in 2002 in the Department of Santa Cruz, Bolivia, where the disease had not previously been reported. Two cases were initially reported. The first case was a physician infected with Laguna Negra virus during a weekend visit to his ranch. Four other persons living on the ranch were IgM antibody-positive, two of whom were symptomatic for mild hantavirus pulmonary syndrome. The second case was a migrant sugarcane worker. Although no sample remained to determine the specific infecting hantavirus, a virus 90% homologous with Río Mamoré virus was previously found in small-eared pygmy rice rats (Oligoryzomys microtis trapped in the area. An antibody prevalence study conducted in the region as part of the outbreak investigation showed 45 (9.1% of 494 persons to be IgG positive, illustrating that hantavirus infection is common in Santa Cruz Department. Precipitation in the months preceding the outbreak was particularly heavy in comparison to other years, suggesting a possible climatic or ecological influence on rodent populations and risk of hantavirus transmission to humans. Hantavirus infection appears to be common in the Santa Cruz Department, but more comprehensive surveillance and field studies are needed to fully understand the epidemiology and risk to humans.

    New diseases known locally as 'hoja de perejil' of tomato (Lycopersicon esculentum Mill) and 'brotes grandes' of potato (Solanum tuberosum L.) were first recognized in surveys of production fields in Bolivia during 2000-2003. Alfalfa (Medicago sativa) witches' broom and little leaf diseases of native weeds Morrenia variegata and mora-mora (Serjania perulacea) were also identified near to production fields. Phytoplasma aetiology was attributed to each of these diseases following detection and initial identification of aster yellows group (16SrI) phytoplasmas in all five diseased plant species. While potato, alfalfa and mora-mora plants contained indistinguishable 16SrI-B strains, 'hoja de perejil' (THP) and morrenia little leaf (MVLL)-associated phytoplasma strains shared 97.5 % 16S rRNA gene sequence similarity with 'Candidatus Phytoplasma asteris' and related strains and <95 % similarity with all other 'Candidatus Phytoplasma' species. Phylogenetic analysis of 16S rRNA gene sequences indicated that the THP and MVLL phytoplasmas represent a novel lineage within the aster yellows (16SrI) group and, on the basis of unique 16S rRNA gene sequences, we propose that THP and MVLL phytoplasmas represent 'Candidatus Phytoplasma lycopersici', with THP as the reference strain.

  5. The compatibility of agricultural intensification in a global hotspot of smallholder agrobiodiversity (Bolivia).

    2013-02-19

    Integrating the conservation of biodiversity by smallholder farmers with agricultural intensification is increasingly recognized as a leading priority of sustainability and food security amid global environmental and socioeconomic change. An international research project investigated the smallholder agrobiodiversity of maize (corn) in a global hotspot (Bolivia) undergoing significant intensification. Peach-based intensification was pronounced (300-400%) and prolonged (2000-2010) in study areas. Intensification and maize agrobiodiversity were found to co-occur within smallholder landscapes. Interactions of these field systems did not trigger land-change tipping points leading to landrace extirpation. By 2010 maize landraces in the study areas still demonstrated high levels of taxonomic and ecological biodiversity and contributed significantly to this crop's agrobiodiversity at national (31%) and hemispheric (3%) scales. Social and ecological resilience and in situ conservation of the maize agrobiodiversity by Bolivian smallholders was enabled through robust linkages to off-farm migration; resource access and asset capabilities among both traditional and nontraditional growers; landrace agroecology and food uses; and innovative knowledge and skills. The smallholders' resilience resulting from these linkages was integral to the conditional success of the in situ conservation of maize agrobiodiversity. Environment-development interactions both enabled smallholders' agrobiodiversity resilience and influenced the limits and vulnerability of agrobiodiversity. Scientific policy recommendations regarding land-use planning and sustainability analysis are targeted to specific Río+20 priorities for agrobiodiversity.

    The glaciers in the Cordillera Quimza Cruz (Tres Cruces) and two smaller Bolivian massifs represent the southernmost tropical glaciers found along the eastern margin of the Andes. Their marginal location makes them of particular interest. The extent of glaciers in the mid 1970s was determined though digitization of the published glacier inventory of Bolivia. In 1975, extent of glaciers in the Tres Cruces region was approximately 55.4 square kilometers. More recent extents were determined from Landsat and ASTER satellite images. Cloud-free Landsat images from 1986, 1992 and 2000 were georegistered and surface reflectances were computed. Normalized Difference Snow Index (NDSI) images were then computed and thresholded to create binary maps of snow- and glacier-covered pixels. From 1975 through 2000, the Tres Cruces Region lost a significant amount of its glacier area. Of the area identified as being glacier covered in 1975 only 27.4 square kilometers (49%) were identified as containing snow and ice in Landsat images from 2000. The glacier retreat time series is being updated as part of an ongoing undergraduate research program. More recent retreat mapped from multiple ASTER images from 2000-2006 indicates that glacier recession is continuing. Changes in glacier hypsometries indicate that much of the areal loss has occurred at lower altitudes. The influence of aspect on glacier retreat is the next area of investigation.

  7. Visibility of latin american scientific publications: the example of Bolivia (Portuguese original version

    Full Text Available The discussion on the state of the art of scientific publications in Latin American countries generally restricts itself to its supposedly low visibility. This affirmation is generally conditioned to the exclusive use of large international databases, mainly of the USA and Europe, which include thousands of scientific publications that have marginalized a large part of the scientific literature produced in peripheral countries. Given this fact of low visibility, it became imperative for some Latin American countries, beginning in the 90s (20th Century, to develop their own mechanisms of projection of the results of their own scientific production. The experiences constitute an example for countries that, having significant scientific production, still do not have the means to facilitate access to local scientific publications. Although Bolivia still remains distant from these initiatives, a series of studies were identified that show the existence of a tradition of publication in scientific magazines and interest in their visibility, on a local and international level, which demands attention to the most adequate mechanisms in order to carry this out.

    Polychlorinated biphenyls are persistent organic pollutants that have been used for decades in several industrial applications. Although production of polychlorinated biphenyls was restricted from the 1970s in most countries, substantial amounts remain in old equipment and buildings and they have been detected in various environmental and biological matrices. The main objective of this study was to analyze predictors of the combined exposure to three non-dioxin-like polychlorinated biphenyls (congeners 138, 153 and 180) in serum and adipose tissue from an adult cohort (n=112) living in the city of Santa Cruz de la Sierra (Bolivia) and surrounding towns/villages. A second aim was to identify modifiers that might influence the statistical associations found, using crude, partially-adjusted, and global multiple linear regression models. Main predictors of serum concentrations were occupation and fatty food consumption, while those for adipose tissue concentrations included age, smoking habit, fatty food consumption, and residence. The differences between the two matrices might be derived from their biological meaning, given that adipose tissue concentrations are an indicator of chronic exposure to polychlorinated biphenyls while serum levels are a good predictor of ongoing exposure and the mobilization of polychlorinated biphenyls stored in fatty tissues. Body mass index was found to be an important modifier of these associations.

    In an attempt to prevent diarrhoea in a rural community in central Bolivia, an international non-governmental organization implemented a pilot project to improve drinking water quality using gravity-fed, household-based, ceramic water filters. We assessed the performance of the filters by conducting a five-month randomized controlled trial among all 60 households in the pilot community. Water filters eliminated thermotolerant (faecal) coliforms from almost all intervention households and significantly reduced turbidity, thereby improving water aesthetics. Most importantly, the filters were associated with a 45.3% reduction in prevalence of diarrhoea among the study population (p = 0.02). After adjustment for household clustering and repeated episodes in individuals and controlling for age and baseline diarrhoea, prevalence of diarrhoea among the intervention group was 51% lower than controls, though the protective effect was only borderline significant (OR 0.49, 95% CI: 0.24, 1.01; p = 0.05). A follow-up survey conducted approximately 9 months after deployment of the filters found 67% being used regularly, 13% being used intermittently, and 21% not in use. Water samples from all regularly used filters were free of thermotolerant coliforms.

    In the Andes, as elsewhere, infanticide is a difficult challenge that remains largely undocumented and misunderstood. From January to March 2004 we used community-based vital event surveillance systems, discussions with health staff, ethnographic interviews, and focus group discussions among Aymara men and women from two geographically distinct sites in the Andes of Bolivia to provide insights into the practice of infanticide. We noted elevated mortality at both sites. In one location, suspected causes of infanticide were especially high for girls. We also observed that community members maintain beliefs that justify infanticide under certain circumstances. Among the Aymara, justification for infanticide was both biological (deformities and twinship) and social (illegitimate birth, family size and poverty). Communities generally did not condemn killing when reasons for doing so were biological, but the taking of life for social reasons was rarely justified. In this cultural context, strategies to address the challenge of infanticide should include education of community members about alternatives to infanticide. At a program level, planners and implementers should target ethnic groups with high levels of infanticide and train health care workers to detect and address multiple warning signs for infanticide (for example, domestic violence and child maltreatment) as well as proxies for infant neglect and abuse such as mother/infant separation and bottle use.

    This study examined the association between food insecurity, determined by a modified version of the U.S. Household Food Security Survey Module (US HFSSM), and total daily per capita (DPC) consumption (measured as household expenditures) in Bolivia, Burkina Faso, and the Philippines. Household food insecurity was determined by an adapted 9-item US HFSSM version. A short version of the World Bank's Living Standards Measurement Study (LSMS) consumption module measured household expenditures. Focus groups were used to adapt the survey instrument to each local context. The sample (n approximately 330 per country) includes residents of urban and rural areas. A 12-month food expenditure aggregate was generated as part of the total household expenditures calculation. DPC food expenditure, which represented over 60% of the total household consumption, as well as expenditures on specific food groups correlated with food insecurity both as a continuous Food Insecurity Score (FinSS) and a tricategorical food insecurity status variable. ANOVA and regression analysis were executed adjusting for social and demographic covariates. Food-secure households have significantly higher (P expenditures as well as expenditures on animal source foods, vegetables, and fats and oils than moderately and severely food-insecure households. The results offer evidence that the US HFSSM is able to discriminate between households at different levels of food insecurity status in diverse developing world settings.

    The mature fruits of three species of algarroba found in Bolivia (Prosopis chilensis (Molina) Stunz, P. alba Grisebach y P. nigra (Grisebach) Hieronymus) and of one of Brazil (P. juliflora (SW) DC) were analysed for some nutritional and antinutritional factors. P. nigra showed the highest levels of crude protein (11.33 g/100 g dry matter-DM) and ashes (4.12 g/100 g DM). P. juliflora presented the lowest levels of lipids (0.79 g/100 g DM), crude protein (8.84 g/100 g DM) and dietary fiber (40.15 g/100 g DM), and the highest levels of non reducing sugar (52.51 g/100 g DM) and in vitro protein digestibility (66.45%). Trypsin inhibitors concentration (0.29 to 9.32 UTI/mg DM) was inferior to that of raw soy; P. juliflora presented the higher values. Regarding saponin, hemagglutinin and poliphenol values, the levels found are considered low. As for nitrates, the levels found were higher than those reported for peas and beans, with P. chilensis presenting the highest value (2.92 g NO3(-)/kg DM). The levels of phytate varied from 1.31 a 1.53 g/100 g.

  13. An ethnography of nonadherence: culture, poverty, and tuberculosis in urban Bolivia.

    The author conducted a focused descriptive ethnographic study of nonadherence with tuberculosis (TB) therapy among Aymara-speaking residents of the city of La Paz, Bolivia. A cohort of patient-informants was identified from the District III TB Control Registry of La Paz as having been nonadherent with their TB medication protocol. From June to August 1998, ethnographic material was collected through participant-observation and repeated interviews and visits in homes, workplaces, clinics, and the community. Ethnographic analysis revealed structural barriers to be more important than cultural differences in the production of nonadherence. Though informants maintained a variety of beliefs and practices related to Aymara medicine, the majority of patients were comfortable with a biomedical model of tuberculosis and maintained belief in the efficacy of antituberculosis chemotherapy and desire to finish treatment. Patients overwhelmingly cited hidden costs of treatments, poor access to care, ethnic discrimination, and prior maltreatment by the health system as reasons for abandoning treatment. These data suggest that overemphasis of cultural difference without exploration of other social dimensions of health care delivery can obscure a more practical understanding of nonadherence in marginalized populations.

    Full Text Available BACKGROUND: The causative agent of Chagas disease, Trypanosoma cruzi, is divided into 6 Discrete Typing Units (DTU: Tc I, IIa, IIb, IIc, IId and IIe. In order to assess the relative pathogenicities of different DTUs, blood samples from three different clinical groups of chronic Chagas disease patients (indeterminate, cardiac, megacolon from Bolivia were analyzed for their circulating parasites lineages using minicircle kinetoplast DNA polymorphism. METHODS AND FINDINGS: Between 2000 and 2007, patients sent to the Centro Nacional de Enfermedades Tropicales for diagnosis of Chagas from clinics and hospitals in Santa Cruz, Bolivia, were assessed by serology, cardiology and gastro-intestinal examinations. Additionally, patients who underwent colonectomies due to Chagasic magacolon at the Hospital Universitario Japonés were also included. A total of 306 chronic Chagas patients were defined by their clinical types (81 with cardiopathy, 150 without cardiopathy, 100 with megacolon, 144 without megacolon, 164 with cardiopathy or megacolon, 73 indeterminate and 17 cases with both cardiopathy and megacolon. DNA was extracted from 10 ml of peripheral venous blood for PCR analysis. The kinetoplast minicircle DNA (kDNA was amplified from 196 out of 306 samples (64.1%, of which 104 (53.3% were Tc IId, 4 (2.0% Tc I, 7 (3.6% Tc IIb, 1 (0.5% Tc IIe, 26 (13.3% Tc I/IId, 1 (0.5% Tc I/IIb/IId, 2 (1.0% Tc IIb/d and 51 (25.9% were unidentified.

    2004-03-01

    Full Text Available Fossil plants belonging to the morphogenera Glossopteris, Pecopteris and Asterotheca were collected from the upper part of the Chutani Formation (Titicaca Group, near the town of San Pablo de Tiquina, on the southeastern shore of Lake Titicaca (northern Altiplano, Bolivia. This paper presents the first description of specimens of the morphogenus Glossopteris from Bolivia. The Bolivian specimens of Glossopteris consist of poorly-preserved impressions, although they present the diagnostic features of this morphogenus. They are fragments of leaves with secondary veins of taeniopterid-type, typical of glossopterids from Late Permian deposits of Gondwana. The only species of Pecopteris confirmed in the first part of this study, i.e. P. dolianitii Rösler and Rohn (see Vieira et al. 2004, was previously reported from the Late Permian beds of the Rio do Rasto and Estrada Nova formations in the Paraná Basin (southern Brazil. Therefore, a Late Permian age is proposed for the fossil plant-bearing beds of the Chutani Formation based on the analyzed assemblage. The phytogeographic implications of this new find are briefly analyzed.Plantas fósseis, pertencentes aos morfo-gêneros Glossopteris, Pecopteris e Asterotheca, foram coletadas na porção superior da seção aflorante da Formação Chutani, próxima ao povoado de San Pablo de Tiquina, sudeste do lago Titicaca (Altiplano norte, Bolívia. Este trabalho apresenta a primeira descrição de espécimes do morfo-gênero Glossopteris provenientes da Bolívia. Os espécimes estudados de Glossopteris consistem em impressões foliares pobremente preservadas nas quais feições diagnósticas estão presentes. Os fragmentos foliares apresentam venação secundária do tipo teniopteróide, uma característica típica de glossopterídeas encontradas em depósitos do Permiano Superior do Gondwana.

    Full Text Available Background: Mobile health (m-health work in low and middle-income countries (LMICs mainly consists of pilot programmes with an unclear path to scaling and dissemination. We describe the deployment and testing of an m-health platform for non-communicable disease (NCD self-management support in Bolivia. Methods: 364 primary care patients in La Paz with diabetes or hypertension completed surveys about their use of mobile phones, health and access to care. 165 of those patients then participated in a 12-week demonstration of automated telephone monitoring and self-management support. Weekly Interactive Voice Response (IVR calls were made from a platform established at a university in La Paz, under the direction of the regional health ministry. Results: 37% of survey respondents spoke indigenous languages at home, and 38% had six or fewer years of education. 82% had a mobile phone; half (45% used text messaging with a standard phone, and 9% had a smartphone. Smartphones were least common among patients who were older, spoke indigenous languages, or had less education. IVR programme participants completed 1007 self-management support calls, with an overall response rate of 51%. IVR call completion was lower among older adults, but was not related to patients’ ethnicity, health status or healthcare access. IVR health and self-care reports were consistent with information reported during baseline interviews. Patients’ likelihood of reporting excellent, very good, or good health (versus fair or poor health via IVR increased during programme participation, and was associated with better medication adherence. Patients completing follow-up interviews were satisfied with the programme, with 19/20 (95% reporting that they would recommend it to a friend. Conclusions: By collaborating with LMICs, m-health programmes can be transferred from higher-resource centres to LMICs and implemented in ways that improve access to self-management support among people

  2. Exhumation history of the southern Altiplano plateau (southern Bolivia) constrained by apatite fission track thermochronology

    2007-02-01

    Although the structural geometry of the Cenozoic Altiplano-Puna plateau in the central Andes is well defined, the temporal evolution of this contractile deformation is poorly constrained. To address this shortcoming, we used apatite fission track thermochronology (AFT) to quantify the cooling and exhumation history along a transect at 21°S in southern Bolivia, through the deformed intermontane Altiplano basin, the doubly vergent thrust belt of the Eastern Cordillera and the inner foreland thrust belt east of the plateau (Interandean Zone). Thermal history modeling combined with published balanced cross sections and stratigraphic data constrain exhumation histories. Exhumation started during the late Eocene (40-36 Ma) in the central Eastern Cordillera, possibly due to bivergent thrusting and Cretaceous rift structure inversion. During the early Oligocene (33-27 Ma), exhumation spread across the study area as the current boundary thrusts of the Eastern Cordillera were activated. The inner west vergent thrust system became active in irregular order until circa 20 Ma, whereas the east vergent Interandean thrust belt formed by eastward propagating deformation since circa 30 Ma. Plateau exhumation continued at ˜0.2 mm/yr until shortening terminated by 11-7 Ma. Shortening within the plateau since circa 30 Ma did not evolve by lateral accretion of thrust wedges; the propagating deformation style is spatially confined to the foreland thrust belt, which initiated coeval to plateau deformation (Interandean Zone) but propagated mainly after circa 10 Ma (Subandean Zone). Early Oligocene plateau-wide tectonically driven exhumation suggests that subduction-related processes had already thermally weakened the continental lithosphere prior to the 27-25 Ma onset of volcanic activity.

  3. Ground Deformation At Uturuncu Volcano, Bolivia: Insights From Finite Element Analysis

    2011-12-01

    This study focuses on a Finite Element Analysis of large-scale ground deformation at Uturuncu volcano in the Altiplano-Puna region of southern Bolivia, for the period 19th May 1996 to 24th December 2000. The amplitude of the line-of-sight displacement from InSAR is 7.4 cm, with a wavelength of around 80 km for that period. We present a series of forward models that explain the observed ground displacement using COMSOL Multiphysics and accounting for both homogeneous and heterogeneous crustal mechanics. The source geometry is approximated using spherical, prolate and oblate source shapes. Crustal heterogeneity is constrained by published seismic velocity profiles that indicate the presence of a large low-velocity body at depths of 17 km below the surface. We deduce that the observed uplift is best explained by a single prolate source, in an heterogeneous medium, centred between 16.1 and 18.9 km below local elevation, with a semi-major axis of 5.2 - 9.8 km, semi-minor axes of 2.9 - 5.5 km and a uniform pressure change of between 5.6 and 29.1 MPa, as determined by bootstrapping of the best-fitting models at 90% confidence. This model can be interpreted to reflect pressurisation, at very modest levels, of a magma chamber within the Altiplano-Puna Magma Body. Further efforts to explore the sensitivity of the model fits to the required source excess pressures are obtained by first-order approximations of varying Poisson ratio with depth, host rock viscoelasticity and source multiplicity. We find that such mechanisms play a primary role in explaining the observed deformation at Uturuncu. However, to further constrain the most likely causative source parameters the full three-dimensional displacement field is required.

  4. Assessing adaptation – Climate change and indigenous livelihood in the Andes of Bolivia

    Full Text Available Based on a case study of Charazani – Bolivia, this article outlines the understanding of adaptive strategies to cope with climate change and its impact on environmental and socioeconomic conditions that are affecting rural livelihoods. Mainly qualitative methods were used to collect and analyze data following the framework for vulnerability assessments of a socio-ecological system. Climate data reveals an increase of precipitation and temperature during the last decades. Furthermore the occurrence of extreme weather events, particularly drought, frost, hailstorms and consequently landslides and fire are increasing. Local testimonies highlight these events as the principle reasons for agricultural losses. This climatic variability and simultaneous social changes were identified as the drivers of vulnerability. Yet, several adaptive measures were identified at household, community and external levels in order to cope with such vulnerability; e.g. traditional techniques in agriculture and risk management. Gradually, farmers complement these activities with contemporary practices in agriculture, like intensification of land use, diversification of irrigation system and use of artificial fertilizers. As part of a recent trend community members are forced to search for new off-farm alternatives beyond agriculture for subsistence. Despite there is a correspondingly large array of possible adaptation measures that families are implementing, local testimonies point out, that farmers often do not have the capacity and neither the economical resources to mitigate the risk in agricultural production. Although several actions are already considered to promote further adaptive capacity, the current target is to improve existing livelihood strategies by reducing vulnerability to hazards induced by climate change.

At first they were sent to Potosí, but later to the tropical Yungas valley where the Spanish colonizers established a so-called “hacienda system” that was based on slave labor, including African-descendants. Due to their isolation, very little attention has been paid so far to ‘Afro-Bolivian’ communities either within the research field of TAST or in genetic population studies. In this study, a total of 105 individuals from the Yungas were sequenced for their mitochondrial DNA (mtDNA) control region, and mitogenomes were obtained for a selected subset of these samples. We also genotyped 46 Ancestry Informative Markers (AIM) in order to investigate continental ancestry at the autosomal level. In addition, Y-chromosome STR and SNP data for a subset of the same individuals was also available from the literature. The data indicate that the partitioning of mtDNA ancestry in the Yungas differs significantly from that in the rest of the country: 81% Native American, 18% African, and 1% European. Interestingly, the great majority of ‘Afro-descendant’ mtDNA haplotypes in the Yungas (84%) concentrates in the locality of Tocaña. This high proportion of African ancestry in the Tocaña is also manifested in the Y-chromosome (44%) and in the autosomes (56%). In sharp contrast with previous studies on the TAST, the ancestry of about 1/3 of the ‘Afro-Bolivian’ mtDNA haplotypes can be traced back to East and South East Africa, which may be at least partially explained by the Arab slave trade connected to the TAST.

    Seven million children under 5 years of age died worldwide in 2011, and one-third had malnutrition. Latin America and Caribbean countries stand out for the notable improvement of their health and nutrition situation, particularly in pregnant women and young children. Nutrition-sensitive interventions such as promoting food security, women's empowerment, social safety nets, clean water, and sanitation, among others, are critical for success. In Bolivia, the program Desnutrición Cero (Malnutrition Zero) was able to reduce mortality from severe malnutrition after 5 years from 25% to less than 5%, based on widespread implementation of the World Health Organization 10-steps protocol for hospitalized care and the application of community management. The Economic Commission for Latin America estimated the cost of malnutrition for Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and the Dominican Republic as US $6,658 million. Approximately 1 million children have dropped out of school because of malnutrition, and as a result, malnourished children have 2 years less schooling, which brings social and economic losses not only to those affected but to society at large. National and international nutrition and food programs developed over the past 50 years have been implemented as integral components of broader strategies of primary healthcare and education, oriented toward preventing deaths and improving the quality of life of low-socioeconomic-status groups. Treating hundreds or thousands of affected children will not solve the global public health problem of malnutrition. Access to adequate amounts of quality foods represents a basic human right and is a necessary precondition for health. In turn, good nutrition and health are prerequisites for human, social, and economic development.

    Introduction Epilepsy is one of the most common neurological diseases in Latin American Countries (LAC) and epilepsy associated with convulsive seizures is the most frequent type. Therefore, the detection of convulsive seizures is a priority, but a validated Spanish-language screening tool to detect convulsive seizures is not available. We performed a field validation to evaluate the accuracy of a Spanish-language questionnaire to detect convulsive seizures in rural Bolivia using a three-stage design. The questionnaire was also administered face-to-face, using a two-stage design, to evaluate the difference in accuracy. Methods The study was carried out in the rural communities of the Gran Chaco region. The questionnaire consists of a single screening question directed toward the householders and a confirmatory section administered face-to-face to the index case. Positive subjects underwent a neurological examination to detect false positive and true positive subjects. To estimate the proportion of false negative, a random sample of about 20% of the screened negative underwent a neurological evaluation. Results 792 householders have been interviewed representing a population of 3,562 subjects (52.2% men; mean age 24.5 ± 19.7 years). We found a sensitivity of 76.3% (95% CI 59.8–88.6) with a specificity of 99.6% (95% CI 99.4–99.8). The two-stage design showed only a slightly higher sensitivity respect to the three-stage design. Conclusion Our screening tool shows a good accuracy and can be easily used by trained health workers to quickly screen the population of the rural communities of LAC through the householders using a three-stage design.

  9. Rural power supply with local management: Examples from Bolivia, India and Nepal

    Local management of rural power supply is being evaluated in a joint research project conducted by Tanzania Electric Supply Company Limited (TANESCO) and Stockholm Environment Institute (SEI) on new approaches to management and organization of rural electrification. The study is based on literature, and on data from eight visited local organizations for management of power supply in Bolivia (4), India (1) and Nepal (3). Common for these countries is that the national, rural electrification programmes have encountered difficulties. Governments have failed to generate enough funds from existing power supply systems to cover the cost for a continued rural electrification. In cases where large private companies exist, they have had few incentives for expanding into rural areas since it is often not profit making. A third category may be defined as local initiators to power supply, private or co-operative. In all these countries, locally managed power supply systems have developed as a complement to governmental and other large scale programmes. The national policies pertaining to rural power supply in general and local management thereof in particular are described for each country. From the study, it appears that local management of rural power supply is a feasible approach in developing countries. Local management of rural power supply can slightly lower the costs of electrification, and it may help accelerate the pace of load development in newly electrified areas. For successful local organizations though, the most significant factor appears to be local peoples` willingness to develop their own area. Important though, is that proper financial and technical assistance is provided the local organizations. Crucial for sound external assistance is that the national rural electrification policies are clear and consistent. 53 refs, 1 fig, 11 tabs

    Full Text Available INTRODUCTION: American tegumentary leishmaniasis (ATL, including mucocutaneous leishmaniasis (MCL and localized cutaneous leishmaniasis (LCL, is endemic in Bolivia. We describe the results of active surveillance of ATL from 2001 to 2006 and assess demographic data related to ATL epidemiology in the Yungas valleys. METHODS: Community-based active ATL surveillance was performed by the institutions SERVIR, CÁRITAS, and the Health Services Department of La Paz, whose files were reviewed retrospectively. A cross-sectional survey was carried out to assess demographic data in two communities. RESULTS: Two thousand nine hundred nine cases of ATL were detected from 2001 to 2006: 2,488 (85.5% corresponded to LCL and 421 (14.5% to MCL. A reduction in the proportion of mucosal cases was observed between 2001 and 2006. The proportion of MCL cases increased with age and was higher among males (15.5% versus 12.1%, p=0.018. The rate of positivity via direct observation of the parasite in dermal scrapings and in parasite cultivation was significantly higher for LCL than for MCL (p<0.001 and p=0.009, respectively. The rate of reactivity in the leishmanin skin test was higher in the group with mucosal lesions (p=0.012. The cross-sectional survey showed that 40% of the families had emigrated from the Altiplano. CONCLUSIONS: It is necessary to undertake continuous case detection of ATL in the area, where the disease presents a high rate of mucosal cases. Increasing incidence seems to be associated with immigration and continuous deforestation to expand the crop-growing areas.

  11. Referéndum y asamblea constituyente: autonomías departamentales en Bolivia.

    Directory of Open Access Journals (Sweden)

    Fernando Mayorga Ugarte.

    2006-12-01

    Full Text Available On 2 July 2006, Bolivia held a national referendum about departamental autonomy as part of the process of state decentralization and as an institutional response to the dire political and social crisis. The inclusion in the constitution of figures such as referendum, constitutional assembly and citizen legislative initiation was the response to the social demands and unrest given under the framework of semi-direct democracy which allowed for an institutional solution to them. Even though the law that called for the referendum defines its national character, in several articles it states that a regime of departamental autonomy will apply immediately after the new Constitution is ratified in those departments where the referendum question was approved by a simple majority of the vote. This dual interpretation with regards to the mandatory nature of the results — at the national or the departamental level — is added to the debate about the nature of the autonomies.The party of the government, whose position won in the referendum and won a majority of the constitutional assembly, sketches a proposal that includes different versions of autonomy — indigenous, regional, provincial, cantonal, communal — that run counter, in some instances, to the departamental autonomies. In sum, the referendum on departamental autonomy, far from solving the problem, has transfered it to the constitutional assembly which puts at risk the democratic legitimacy of its decisions given that the new constitution must answer the demands of diverse political and social actors. Aside from these dynamics, this experience of citizen participation in the decisiom-making process is an example of the positive impact of an institutional reform in the strengthening of the democratic legitimacy and the efficacy of political institutions.

    1985-01-01

    A relatively high leishmanial infection rate was found in the phlebotomine sandfly Lutzomyia longipalpis collected from three villages of the Los Yungas region (Department of La Paz, Bolivia). 2,578 female sandflies were dissected. In three houses surveyed in Santa Barbara promastigote infection rates of Lu. longipalpis were 4.2, 2.2 and 3.2% respectively. Anatomical localization of the infection in the insect, and biochemical characterization of the strains indicate that the parasite belongs to the Leishmania donovani complex. The geographical area and the biotopes of Lu. longipalpis are discussed in relation to the vector-parasite relationship.

    This paper argues that migration is better defined as an adaptive response to socio-economic, cultural, political and environmental transformations, in most instances closely linked to the need to diversify income sources and reduce dependency on natural resources. Drawing on case studies in Bolivia, Senegal and Tanzania, it describes how environmental change at the local level interacts with other factors to shape migration patterns, and how such patterns in turn affect the livelihoods and resilience of individuals, households and communities in areas experiencing the impacts of climate change in the form of desertification, soil degradation, disrupted rainfall patterns and changes in temperature.

Es un estudio descriptivo de tendencias temporales de la cobertura vacunal y de la incidencia de enfermedades vacunables por departamento: Ambos datos se confeccionaron en base a fuentes secundarias. Las incidencias se calcularon en base a la información del Sistema de Vigilancia Epidemiológica del Sistema Nacional de Salud y la población censada en cada departamento. La cobertura de vacunación se calculó según la información de dosis de vacunas administradas disponible en el Instituto Nacional de Estadística y la población diana censada. Los datos son inconstantes y en muchos casos inexistentes. Con la información disponible podemos señalar que la distribución de las enfermedades así como la cobertura de vacunación es muy heterogénea en Bolivia. Debe trabajarse en reforzar el sistema de vigilancia para conseguir datos confiables y poder realizar planes específicos en cada departamento para combatir las enfermedades que mayor carga de morbilidad producen.

    The Bacillus cereus group sensu lato includes six closely-related bacterial species: Bacillus cereus, Bacillus anthracis, Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides and Bacillus weihenstephanensis. B. thuringiensis is distinguished from the other species mainly by the appearance of an inclusion body upon sporulation. B. weihenstephanensis is distinguished based on its psychrotolerance and the presence of specific signature sequences in the 16S rRNA gene and cspA genes. A total of seven housekeeping genes (glpF, gmK, ilvD, pta, purH, pycA and tpi) from different B. thuringiensis serovars and B. weihenstephanensis strains were amplified and their nucleotide sequences determined. A maximum likelihood phylogenetic tree was inferred from comparisons of the concatenated sequences. B. thuringiensis serovars navarrensis, bolivia and vazensis clustered not with the other B. thuringiensis serovars but rather with the B. weihenstephanensis strains, indicative of a common phylogeny. In addition, specific signature sequences and single nucleotide polymorphisms common to B. thuringiensis serovars navarrensis, bolivia and vazensis and the B. weihenstephanensis strains, and absent in the other B. thuringiensis serovars, were identified.

    2006-12-01

    Full Text Available La diferenciación social de los indígenas, en la región andina de Bolivia, tiene como telón de fondo la noción de «desanclaje». Según esta, el tránsito de la sociedad agraria hacia la sociedad industrial produce una forma de «extrañamiento» del ser humano respecto de sus relaciones locales y tradicionales de presencia, para estructurarlas luego en intervalos espaciales y temporales de la modernidad y el capitalismo, en su forma estatal-nacional. En este proceso, la educación desempeña un papel fundamental que el artículo hace visible a partir de una de las consecuencias centrales de la integración diferenciada y desigual de los indígenas al orden estatal, ello a través de la división social del trabajo que deviene en sujetos intelectuales y manuales. Todos estos aspectos son tratados desde metáforas corporales que aluden a la compleja administración de signos y significantes bajo los formatos comprensivos de la colonización y el capitalismo en los Andes de Bolivia.

    The risk of domestic transmission of Trypanosoma cruzi (Chagas) by sylvatic triatomines was assessed in an isolated area of the subandean region of Bolivia. None of the 390 residents examined had serological evidence of infection. Two sylvatic triatomine species, Eratyrus mucronatus (Stål) and Triatoma sordida (Stål), were found in houses and in peridomestic structures. The collection of nymphal instars of both species from some houses indicated possible domesticity. Microscopic examination of feces from 92 insects showed no parasites, and cultures from the guts of 30 insects were negative. Nevertheless, a polymerase chain reaction (PCR) test performed on the same fecal samples showed the presence of T. cruzi DNA in 19.1 and 12.5% of E. mucronatus and T. sordida, respectively. These 16 PCR-positive samples were hybridized with 2 T. cruzi-specific probes known from the domestic cycle in Bolivia (clones 20 and 39). At least 1 of these clones was identified in 7 bugs (5 E. mucronatus and 2 T. sordida). Moreover, no hybridization was observed with these probes in S E. mucronatus and 1 T. sordida samples that showed an amplified band by PCR. These data indicated that T. cruzi clones, genetically unrelated to clones 20 and 39, also were circulating in this area. Based on these results, the 2 sylvatic triatomine species encountered in Apolo should not be overlooked as possible local vectors of T. cruzi.

Methods: Overall, 126 healthcare providers (46 from Bolivia, 39 from Ecuador, and 41 from Nicaragua took part in this qualitative study. During a series of moderated discussions, they provided written opinions about the accessibility and appropriateness of ASRH services and suggestions for its improvement. The data were analyzed by employing a content analysis methodology. Results: Study participants emphasized managerial issues such as the prioritization of adolescents as a patient group and increased healthcare providers’ awareness about adolescent-friendly approaches. They noted that such an approach needs to be extended beyond primary healthcare centers. Schools, parents, and the community in general should be encouraged to integrate issues related to ASRH in the everyday life of adolescents and become ‘gate-openers’ to ASRH services. To ensure the success of such measures, action at the policy level would be required. For example, decision-makers could call for developing clinical guidelines for this population group and coordinate multisectoral efforts. Conclusions: To improve ASRH services within primary healthcare institutions in three Latin American countries, primary healthcare providers call for focusing on improving the youth-friendliness of health settings. To facilitate this, they suggested engaging with key stakeholders, such as parents, schools, and decision-makers at the policy level.

    Full Text Available To increase our knowledge of the natural susceptibility of Triatoma infestans to an organophosphate insecticide, we performed toxicological and biochemical studies on three sylvatic populations from Bolivia and two populations from domestic dwellings from Bolivia and Argentina. Fifty-per-cent lethal doses (LD50 were determined based on the topical application of fenitrothion on first instar nymphs and mortality was assessed at 24 h. Both type of populations exhibited LD50ratios significantly higher than 1 with a range of the values (1.42-2.47; the maximum value were found in a sylvatic (-S population, Veinte de Octubre-S. Samples were biochemically analysed using a glutathione S-transferase activity assay. The highest significant activity was obtained for Veinte de Octubre-S and the lowest activity was obtained for the reference population (102.69 and 54.23 pmol per minute per mg of protein respectively. Two out of the three sylvatic populations (Veinte de Octubre-S and Kirus Mayu-S exhibited significantly higher glutathione S-transferase activity than that of the reference population. Based on this analysis of the natural susceptibility of this organism to organophosphate insecticides, continental and focal surveys of organophosphate susceptibility should be conducted to evaluate the evolution and distribution of this phenomenon.

    This paper presents the results of CBERS-2B' Brazilian Remote Sensing Satellite to help to monitor the Bolivia-Brazil Gas Pipeline. The CBERS-2B is the third satellite launched in 2007 by the CBERS Program (China-Brazil Earth Resources Satellite) and the innovation was the HRC camera that produces high resolution images. It will be possible to obtain one complete coverage of the country every 130 days. In this study, 2 images from different parts of the Bolivia- Brazil Gas Pipeline were selected. Image processing involved the geometric registration of CBERS-2B satellite images with airborne images, contrast stretch transform and pseudo color. The analysis of satellite and airborne images in a GIS software to detect third party encroachment was effective to detect native vegetation removal, street construction, growth of urban areas, farming and residential/industrial land development. Very young, the CBERS-2B is a good promise to help to inspect the areas along the pipelines. (author)

    Full Text Available (1 The high-altitude (4,500+ m Andean mountain range of north-western Bolivia contains many peatlands. Despite heavy grazing pressure and potential damage from climate change, little is known about these peatlands. Our objective was to quantify carbon pools, basal ages and long-term peat accumulation rates in peatlands in two areas of the arid puna ecoregion of Bolivia: near the village of Manasaya in the Sajama National Park (Cordillera Occidentale, and in the Tuni Condoriri National Park (Cordillera Real. (2 We cored to 5 m depth in the Manasaya peatland, whose age at 5 m was ca. 3,675 yr. BP with a LARCA of 47 g m-2 yr-1. However, probing indicated that the maximum depth was 7–10 m with a total estimated (by extrapolation carbon stock of 1,040 Mg ha-1. The Tuni peat body was 5.5 m thick and initiated ca. 2,560 cal. yr. BP. The peatland carbon stock was 572 Mg ha-1 with a long-term rate of carbon accumulation (LARCA of 37 g m-2 yr-1. (3 Despite the dry environment of the Bolivian puna, the region contains numerous peatlands with high carbon stocks and rapid carbon accumulation rates. These peatlands are heavily used for llama and alpaca grazing.

    The salar de Uyuni, a 100km x 100km salt flat in the Andean Altiplano of southern Bolivia, is the largest dry lake on Earth. The size, high albedo and remarkable flatness of the salar make it an ideal reference surface for satellite-based altimeters - in particular, the Geoscience Laser Altimeter System (GLAS) to be flown on the Ice, Cloud and Land Elevation Satellite (ICESat) - especially with regard to range measurements and waveform analysis of return signals. A simple reference surface such as the salar can be mapped by ground-based surveying, although the sheer size of the area requires adaptations to standard survey techniques. We describe a survey of the salar de Uyuni carried out with car-mounted kinematic GPS over a seven-day period in September 2002. We divided the salar surface into a number of survey grids that were driven in multiple directions to yield redundant measurements and corresponding error statistics at grid crossover points. Adjacent grids were overlapped so we could also determine errors between grids and over multi-day time periods. In addition, we set up five fixed GPS sites on the salar to serve as local survey control in post-processing. These fixed sites will be used to map ionospheric effects and interpolate them to the roving GPS receivers. If successful, this will allow reprocessing of GPS solutions using L1 data only, with a corresponding reduction in noise compared to solutions using the standard ionosphere-free LC combination. We present our surveyed topography of the eastern half of the salar de Uyuni, comparing it to previously-published elevation measurements and to the best geoid model available for the region. We show the close relationship between the topography of the salar and the shape of the geoid, a result we had expected since the salar is flooded each austral summer to an almost uniform depth. We also demonstrate knowledge of the surface height of the salar to within the measurement error specified for the GLAS

    Full Text Available INTRODUCTION: A descriptive, entomological and seroepidemiological study on Chagas disease was conducted in a place of recent occupation on the outskirts of Cochabamba, Bolivia: Avaroa/Primer de Mayo (population:3,000, where the socio-economic level is low and no control measures have been made available. METHODS: The immunofluorescent antibody test (IFAT was used for IgG and IgM anti-Trypanosoma cruzi antibodies in filter paper bloodspot eluates from 128 subjects (73 females, 55 males selected by systematic sampling. Concerning each subject age, gender, birthplace, occupation, duration of residence and building materials used in their houses were recorded. Vectors were captured both in domestic and peridomestic environments. RESULTS: Seropositive, 12.5% (16/128: females, 15.1% (11/73; males, 9.1% (5/55. Average time of residence: 6.1 years for the whole population sample and 7.4 years for the seropositive subjects. Most houses had adobe walls (76.7% , n= 30, galvanized iron rooves (86.7% and earthen floors (53.4% 80% of the walls had crevices. One hundred forty seven specimens of Triatoma infestans were captured, of which 104 (70.7% were domestic, and 1 peridomestic Triatoma sordida. Precipitin host identification: birds, 67.5%; humans, 27.8%; rodents, 11.9%; dogs, 8.7%; cats, 1.6%. House infestation and density indices were 53.3 and 493.0 respectively. We found 21 (14.3% specimens of T. infestans infected with trypanosomes, 18 (85.7% of which in domestic environments. DISCUSSION: The elements for the vector transmission of Chagas disease are present in Avaroa/Primer de Mayo and the ancient custom of keeping guinea pigs indoors adds to the risk of human infection. In neighboring Cochabamba, due to substandard quality control, contaminated blood transfusions are not infrequent, which further aggravates the spread of Chagas disease. Prompt action to check the transmission of this infection, involving additionally the congenital and transfusional

    Full Text Available Abstract Background Diarrhoea is the second leading cause of childhood mortality, with an estimated 1.3 million deaths per year. Promotion of Solar Water Disinfection (SODIS has been suggested as a strategy for reducing the global burden of diarrhoea by improving the microbiological quality of drinking water. Despite increasing support for the large-scale dissemination of SODIS, there are few reports describing the effectiveness of its implementation. It is, therefore, important to identify and understand the mechanisms that lead to adoption and regular use of SODIS. Methods We investigated the behaviours associated with SODIS adoption among households assigned to receive SODIS promotion during a cluster-randomized trial in rural Bolivia. Distinct groups of SODIS-users were identified on the basis of six compliance indicators using principal components and cluster analysis. The probability of adopting SODIS as a function of campaign exposure and household characteristics was evaluated using ordinal logistic regression models. Results Standardised, community-level SODIS-implementation in a rural Bolivian setting was associated with a median SODIS use of 32% (IQR: 17-50. Households that were more likely to use SODIS were those that participated more frequently in SODIS promotional events (OR = 1.07, 95%CI: 1.01-1.13, included women (OR = 1.18, 95%CI: 1.07-1.30, owned latrines (OR = 3.38, 95%CI: 1.07-10.70, and had severely wasted children living in the home (OR = 2.17, 95%CI: 1.34-3.49. Conclusions Most of the observed household characteristics showed limited potential to predict compliance with a comprehensive, year-long SODIS-promotion campaign; this finding reflects the complexity of behaviour change in the context of household water treatment. However, our findings also suggest that the motivation to adopt new water treatment habits and to acquire new knowledge about drinking water treatment is associated with prior engagements in sanitary

    Assessing climatological trends and extreme events requires high-quality data. However, for many regions of the world, observational data of the desired quality is not available. In order to eliminate errors in the data, quality control (QC) should be applied before data analysis. If the data still contains undetected errors and quality problems after QC, a consequence may be misleading and erroneous results. A region which is seriously affected by observational data quality problems is the Central Andes. At the same time, climatological information on ongoing climate change and climate risks are of utmost importance in this area due to its vulnerability to meteorological extreme events and climatic changes. Beside data quality issues, the lack of metadata and the low station network density complicate quality control and assessment, and hence, appropriate application of the data. Errors and data problems may occur at any point of the data generation chain, e.g. due to unsuitable station configuration or siting, poor station maintenance, erroneous instrument reading, or inaccurate data digitalization and post processing. Different measurement conditions in the predominantly conventional station networks in Bolivia and Peru compared to the mostly automated networks e.g. in Europe or Northern America may cause different types of errors. Hence, applying QC methods used on state of the art networks to Bolivian and Peruvian climate observations may not be suitable or sufficient. A comprehensive amount of Bolivian and Peruvian maximum and minimum temperature and precipitation in-situ measurements were analyzed to detect and describe common data quality problems. Furthermore, station visits and reviews of the original documents were done. Some of the errors could be attributed to a specific source. Such information is of great importance for data users, since it allows them to decide for what applications the data still can be used. In ideal cases, it may even allow to

    Subduction of the Nazca plate in the north central Andes beneath southern Peru and northern Bolivia is of prime importance because of the role it plays in the evolution of topographic features since the late Eocene (~40 Ma). Previous studies based on slab event locations constrained only with teleseismic data defined a broad area of flat slab subduction in central and southern Peru, which transitions to a normally dipping slab beneath the northernmost Altiplano Plateau. We present earthquake locations and focal mechanisms using data from two temporary arrays: the network of 50 broadband seismic stations that were part of the NSF-Continental Dynamics-funded project 'CAUGHT' (Central Andean Uplift and the Geodynamics of High Topography) and the 40 station NSF- Geophysics funded 'PULSE' array (PerU Lithosphere and Slab Experiment). Our earthquake locations provide new information about the geometry of subducting Nazca slab between 13°S to 18°S. A significant clustering of intermediate depth earthquakes at ~15.5°S and 18°S suggests strong and localized release of tectonic stress in the slab perhaps due to bending and unbending. There are not enough intra-slab events at depth greater than 100 km to constrain the flat slab width north of 14°S. Our analyses indicate that the flat slab is at least 10 to 12 km shallower than the previous estimates (e.g. Cahill and Isacks, 1992; Ramos, 2009). Focal mechanisms and stress axis orientation of slab events at ~15.5°S indicate down-dip extension, where the dip changes from subhorizontal to steeply dipping slab. The continuity in the trend of stress suggests that the slab is deformed but not torn where it transitions from flat to steeply dipping. Data from local slab events will eventually be incorporated into a local tomographic body wave inversion to better constrain the velocity structure of the mantle lithosphere and asthenosphere below the Altiplano. This in turn will provide the valuable information on the process

  3. What's causing the world's largest deformation anomaly in southern Bolivia? Insights from Finite Element Analysis

    This study focuses on a Finite Element Analysis of the world's largest recorded ground deformation anomaly in the Altiplano-Puna region of southern Bolivia. We present a series of forward models to construe the 70 km wide ground displacement field identified by satellite geodesy between 1996 and 2000, with a mean inflation rate of ~1.5 cm/yr, centered at Uturuncu volcano. The causative pressure sources simulated in the models have spherical, prolate and oblate shapes and the resulting stresses are solved numerically, accounting for both homogeneous and heterogeneous mechanical rock properties, as well as elastic and time-dependent rheologies and source multiplicity. Crustal heterogeneity is constrained by published seismic velocity profiles that indicate the presence of a large low-velocity region, the Altiplano-Puna Magma Body (APMB), at depths less than roughly 17 km below the surface. For the case of crustal elasticity, we find that the observed uplift is best explained by a single prolate source, in a mechanically heterogeneous medium, centered between 16.1 and 18.9 km below local elevation, with a semi-major axis of 5.2 - 9.8 km, semi-minor axes of 2.9 - 5.5 km and a uniform pressure change of between 5.6 and 29.1 MPa, as determined by bootstrapping of the best-fitting models at 90% confidence. We then further explore the sensitivity of the model fits by first-order approximations of varying Poisson ratio with depth, crustal viscoelasticity and source multiplicity, to account for a wider range of conditions at upper crustal levels in the Altiplano-Puna region. We find that such mechanisms play a primary role in explaining the observed deformation at Uturuncu. Both crustal viscoelasticity and source multiplicity reduce the pressure requirement of a source while maintaining the same amplitude of deformation. But in particular, the presence of a mechanically soft layer at source depths, such as the APMB, significantly alters surface displacement patterns.

    An overwhelming number of applications depend on reliable precipitation estimations. However, over complex terrain in regions such as the Andes or the southwestern Amazon, the spatial coverage of rain gauges is scarce. Two reanalysis datasets, a satellite algorithm and a scheme that combines surface observations with satellite estimations were selected for studying rainfall in the following areas of Bolivia: the central Andes, Altiplano, southwestern Amazonia, and Chaco. These Bolivian regions can be divided into three main basins: the Altiplano, La Plata, and Amazon. The selected reanalyses were the Modern-Era Retrospective Analysis for Research and Applications, which has a horizontal resolution (~ 50 km) conducive for studying rainfall in relatively small precipitation systems, and the Climate Forecast System Reanalysis and Reforecast, which features an improved horizontal resolution (~ 38 km). The third dataset was the seventh version of the Tropical Rainfall Measurement Mission 3B42 algorithm, which is conducive for studying rainfall at an ~ 25 km horizontal resolution. The fourth dataset utilizes a new technique known as the Combined Scheme, which successfully removes satellite bias. All four of these datasets were aggregated to a coarser resolution. Additionally, the daily totals were calculated to match the cumulative daily values of the ground observations. This research aimed to describe and compare precipitations in the two reanalysis datasets, the satellite-algorithm dataset, and the Combined Scheme with ground observations. Two seasons were selected for studying the precipitation estimates: the rainy season (December-February) and the dry season (June-August). The average, bias, standard deviation, correlation coefficient, and root mean square error were calculated. Moreover, a contingency table was generated to calculate the accuracy, bias frequency, probability of detection, false alarm ratio, and equitable threat score. All four datasets correctly

En este artículo se proporcionan algunos elementos de análisis que permitan comprender el reciente cambio en los equilibrios políticos y sociales en Bolivia. Después de un período de alianzas y el apoyo mutuo ante las amenazas de los enemigos externos – en particular, el neoliberalismo y los poderes oligárquicos – los movimientos sociales han entrado recientemente en un momento de fragmentación y disputa sobre el acceso a los mismos espacios físicos, simbólicos y de potencia.

    Full Text Available The dominant paradigm in rural water provision in Bolivia has focused on the provision of infrastructure, whether by government agencies or international cooperation groups. However, the investment in infrastructure has led neither to universal access for all Bolivians nor to consistently high levels of services for those who do have access to a water system. This paper will describe the transition of one international non-profit organisation, Water For People, from supporting dispersed water projects throughout the country towards targeted support of water services at the municipal level, aiming to support permanent universal services. The institutional evolution – including changes in governance, implementation strategy, donor base, and indicators of success – that allowed field programmes to shift from projects to services provides the context for the change of approach in Bolivia. A discussion of the various aspects that have changed in the organisation’s operations in seven municipalities in Bolivia, from the scale of intervention, to municipal-wide planning information and tools, to support to service providers and service authorities, and an increased focus on post-construction monitoring, demonstrates how the Everyone, Forever approach is resulting in a more service- delivery-oriented approach in Bolivia.

The most efficient method for executing new delivery points and maintenance repairs in pipelines is using the 'hot-tapping' technique, because there is no need to stop flow and blow down lines. This paper shows the project, specifications, planning and a detailed job execution to support this new city-gate, using a T split sleeve welded in the pipeline, explaining all the activities. Complex and innovative aspects related to the welding and inspection processes, executed in a API 5L X70 pipe at 92 kgf/cm{sup 2}, are also reported. (author)

    Full Text Available La agricultura es altamente dependiente del clima, y los impactos del cambio climático se sentirán más en los países del Sur, agravando los problemas existentes de degradación de suelos y falta de agua. Las familias de agricultores de escasos recursos particularmente, se verán afectados por las pérdidas de sus cultivos y la posible erosión de su agrobiodiversidad. Esto se agravará porque no cuentan con recursos económicos y tecnologías adecuadas para adaptarse a las consecuencias de los efectos del cambio climático. Los efectos del cambio climático manifestados como el cambio de temperatura, mayor incidencia de sequía, helada, granizo y otros fenómenos naturales, tienen un impacto directo sobre los niveles de producción y rendimiento de los cultivos. El fenómeno niño/niña agudizó por ejemplo la sequía en el oriente boliviano, causando en el presente año dramáticos cambios en la agricultura de Santa Cruz, así en la soya de 290.000 ha sembradas en el año 2015, este año bajo la siembra a 40.000 ha, con una reducción de la superficie cultivada de 276.2%; asimismo hubo efectos catastróficos a nivel de rendimiento, ya que de 2.5 t/ha producidas, bajo a 1.5 t/ha. Similar situación ocurre con el sorgo, el trigo, el maíz, el arroz, el girasol y la chía; y lo mismo está pasando con cultivos de seguridad alimentaria, como la papa, la quinua y las hortalizas en el occidente boliviano. Esto obligará a que el Estado Plurinacional de Bolivia, tenga que posiblemente pensar en importar estos productos para el consumo de la población boliviana, porque sus efectos recién se sentirán en el año 2017. Es notorio el hecho que también habrá un impacto indirecto, ya que el ciclo de los cultivos resulta ser afectado por otros factores, como la proliferación de enfermedades y plagas; así como los cambios en la composición de los suelos, lo que implica que abra pérdida de microorganismos benéficos y menor contenido de materia org

  17. Geometric, Kinematic, and Erosional history of the Central Andean Plateau, northern Bolivia

    Latitudinal changes in topography, climate, and thrust-belt geometry in the Central Andes have lead to conflicting hypotheses that climate or tectonics exert a first-order control on the orogens' evolution. Models of climate/tectonic interactions are limited by a lack of detailed observations for both the long-term deformation and erosion history of the Andean fold-thrust belt. We contribute to this problem by combining a sequentially restored, balanced cross section across the northern Bolivia portion of the thrust belt (15-16°S) with 10 new and 51 previously published mineral cooling ages, documenting the timing and magnitude of exhumation across the cross section. The cross section was balanced and restored using the sinuous bed method. The restored section was also sequentially forward modeled using stratigraphic and cooling age constraints. Results indicate the Eastern Cordillera (EC) records the highest magnitudes of shortening (123 km or 55%). The Interandean zone (IAZ) has shortened 48 km or 30%. In both the EC and IAZ individual thrust sheets are tightly folded and have minor offsets of 1-5 km. The fold-thrust belt of the SAZ has multiple levels of detachments allowing for thrust sheets with large 6-17 km of offset. Total shortening in the SAZ is 66 km or 40%. Total shortening for the entire fold-thrust belt in this region is 276 km (39%). New cooling ages support previously published ages that indicate rapid exhumation of the EC from ~40-25 Ma and distributed exhumation of the entire fold-thrust belt from ~15-0 Ma. Cooling ages in the EC and IAZ do not appear affected by individual thrusts. Integrating the sequential reconstructions with a compilation of mineral cooling ages and onlapping sedimentary basins provides a means of comparing independently derived exhumation estimates and determining long term shortening rates. Combined exhumation estimates suggest ~9 km of exhumation in the EC ~5-9 km in the IAZ and 3-4 km in the SAZ. Long term shortening

    Artisanal gold mining is the main economic activity in the Yani district, Northern Bolivia. In this area abundant orogenic gold deposits constituted by quartz veins hosted in paleozoic turbiditic series that contain either free gold or associated with pyrite. Gold is recovered in processing plants by gravimetric methods using shaking tables in several communities of this district. Previously, miners ground the mineral in ball mills together with mercury. The present study aims to evaluate the effect of mercury used in the gold recovering process to the environment and human health in the Yani district. The assessment was based on the analysis of human hair, sediments and water from the river nearby the processing plant and drinking water from the fountain that supplies these communities. 47 samples of hair from miners and other people from the Yani and Señor de Mayo communities were obtained in 2014 and 52 samples in 2015. All were analysed to evaluate the mercury exposure in these places. The results from the 2014 sampling show a wide range of Hg concentration in hair, especially in Señor de Mayo, with values up to 136 μg/g THg. However, in 2015 among the 43 residents in Señor de Mayo, 29 (67%) exhibit concentrations higher than 2 μg/g THg, with an average value of 5.36 μg/g THg. On the other hand, in Yani only 40% have concentrations above 2 μg/g THg, with an average value of 2.34 μg/g THg. The content in Hg in most of the hair samples exhibit values above the tolerable limits established by the US Environmental Protection Agency (1 μg/g Hg) and the World Health Organisation (WHO, 2 μg/g Hg). These high Hg concentrations are found not only in miners but also in the other members of the community, in spite of low fish consumption in this area. Part of the hair was analysed before and after cleaning. Usually in the second case the content of Hg is reduced, but still show high Hg levels, then probably the atmosphere is polluted with Hg and population is

    2016-03-01

    Este artículo propone que descolonizar es desmontar, de manera radical, el actual sistema de valores y las instituciones que los sustentan. En Bolivia, este es un sistema de dominación que es neocolonial y racista. Aunque se vive la descolonización de la sociedad, desde el año 2009 el gobierno del MAS quebró la posibilidad de una descolonización del Estado. Sin embargo, el gobierno proclama el triunfo de la descolonización sobre la base de que Evo Morales es un presidente indígena. Para dimensionar el alcance de estos debates, el artículo estudia otras corrientes de pensamiento acerca de la descolonización, tales como el indianismo y el katarismo, y el multiculturalismo de Xavier Albó.

    Ceramic water filters have been identified as one of the most promising and accessible technologies for treating water at the household level. In a six-month trial, water filters were distributed randomly to half of the 50 participating households in a rural community in Bolivia; the remaining households continued to use customary water handling practices and served as controls. In four rounds of sampling following distribution of the filters, 100% of the 96 water samples from the filter households were free of thermotolerant coliforms compared with 15.5% of the control household samples. Diarrheal disease risk for individuals in intervention households was 70% lower than for controls (95% confidence interval [CI] = 53-80%; P ceramic water filters enable low-income households to treat and maintain the microbiologic quality of their drinking water.

    Full Text Available Intensive mining and processing of the polymetallic sulfide ore body of Cerro Rico de Potosí (Bolivia has occurred since 1545. To further investigate acid mine drainage (AMD discharges and their link to downstream contamination, data were gathered during two sampling events during the most extreme periods of the dry and wet seasons of one year. Concentrations of Ag, B, Ba, Mo, Sb, Se, Sn and V in AMD and receiving streams were greater than Bolivian discharge limits and receiving water body guidelines as well as international agricultural use standards. High concentrations of rare earth metals have been documented in this area. Results indicate that contamination from mining has a larger scope than previously thought and underscore the importance of remediation.

    2012-01-01

    Full Text Available This paper presents a study of patterns in the distribution and transmission of medicinal plant knowledge in rural Andean communities in Peru and Bolivia. Interviews and freelisting exercises were conducted with 18 households at each study site. The amount of medicinal plant knowledge of households was compared in relation to their socioeconomic characteristics. Cluster analysis was applied to identify households that possessed similar knowledge. The different modes of knowledge transmission were also assessed. Our study shows that while the amount of plant knowledge is determined by individual motivation and experience, the type of knowledge is influenced by the community of residence, age, migratory activity, and market integration. Plant knowledge was equally transmitted vertically and horizontally, which indicates that it is first acquired within the family but then undergoes transformations as a result of subsequent contacts with other knowledge sources, including age peers.

    Yacimientos Petroliferos Fiscales Bolivianos (YPFB) undertook a large seismic evaluation in the southern Altiplano, Bolivia in 1994. As an additional layer of information, sorbed soil gas and Microbial Oil Survey Technique (MOST) geochemical surveys were conducted to evaluate the hydrocarbon microseepage potential. The Wara Sara Prospect had 387 sorbed soil gas samples, collected from one meter depth, and 539 shallow soil microbial samples, collected from 15 to 20 centimeter depth. The sorbed soil gas samples were collected every 500 meters and microbial samples every 250 meters along geochemical traverses spaced 1 km apart. The presence of anmalous hydrocarbon microseepage is indicated by (1) a single hydrocarbon source identified by gas crossplots, (2) the high gas values with a broad range, (3) the high overall gas average, (4) the clusters of elevated samples, and (5) the right hand skewed data distributions.

    The prevalence of infection caused by different categories of diarrhoeagenic E. coli (DEC) strains, including enteroaggregative (EAEC), enteropathogenic (EPEC), enterotoxigenic (ETEC), enteroinvasive (EIEC) and enterohaemorrhagic (EHEC) E. coli, in children who suffered from diarrhoea (n = 3943) or did not have diarrhoea (n = 1026) were analysed in two areas in Bolivia over a period of 4 years. We also analysed the seasonality of DEC infections and severity of diarrhoea in children with DEC infection and compared antibiotic resistance in DEC strains isolated from children with and without diarrhoea. Stool samples were analysed for the presence of DEC by culturing followed by PCR. The most prevalent DEC categories in samples from the children were: EAEC (11.2 %); ETEC (6.6 %); EPEC (5.8 %); and EIEC and EHEC (<1 %). DEC strains were isolated significantly more often from diarrhoea cases (21.6 %) than from controls (17.6 %; P = 0.002). The number of children with diarrhoea associated with EAEC, EPEC and ETEC infections peaked in the Bolivian winter (April-September), although the proportion of DEC-positive stool samples was higher during the warm rainy season (October-March). High levels of antibiotic resistance were detected among the DEC strains. In particular, resistance to tetracycline and sulfamethoxazole-trimethoprim was significantly higher in strains isolated from individuals with diarrhoea than in samples from controls. The severity of disease in children infected with EAEC, EPEC and ETEC varied from mild to severe diarrhoea, although disease severity did not differ significantly between the different DEC categories. ETEC, EPEC and EAEC are commonly found in Bolivia and may cause severe disease in children.

  11. The geologic and geomorphologic evolution of Serranía Huanchaca, eastern Bolivia: The legendary ``Lost World''

    Science.gov (United States)

    Litherland, M.; Power, G.

    Serranía Huanchaca is a remote tableland in eastern Bolivia with an area of about 7000 km 2. It is bounded by precipitous cliffs which overlook the densely forested lowlands of the southern Amazonian basin. Descriptions of the cliffs by the English explorer Col. Fawcett formed the basis for the novel The Lost World by Arthur Conan Doyle. The serranía is composed mainly of unmetamorphosed arenaceous Proterozoic sediments which comprise the Huanchaca Group. This unconformably overlies a basement complex of schists and granites which were generated at c. 1300 Ma. The Huanchaca Group sediments are interpreted as fluvial deposits which were derived from the north. Around 900 Ma, these sediments were intruded by a continental tholeiitic sill and dike complex, while the marginal effects of the Aguapei Mobile Belt produced a pattern of monoclinal folds in the form of a structural basin. This basin was later infilled by sandstones of the Macacos Group, of possible Cretaceous age, and the entire sequence was affected by the Cretaceous post-Macacos episode of faulting, jointing and minor folding, accompanied by the formation of siliceous reefs of quartz breccia and chert. The geomorphologic evolution of the serranía can be related to successive Tertiary cycles of erosion which, in order of decreasing age, produced the Pega Pega, Paucerna, and San Ignacio planation surfaces and associated laterites as well as sandstones, cherts, and silcretes found locally over the serranía. The keel of more resistant Huanchaca Group quartzites has helped preserve the Pega Pega and Paucerna surfaces over the serranía; elsewhere in eastern Bolivia, these have been removed by the San Ignacio cycle of erosion.

El uso del concepto de subsidiaria extranjera en el país, más allá de la definición tradicional de sucursal extranjera, permite apreciar perspectivas diferentes a las habitualmente observadas sobre el desempeño de los bancos extranjeros en Bolivia. Adicionalmente, un análisis definido por las etapas de la evolución de la cartera, con aproximaciones a indicadores macro y micro, utilizando la información publicada por los bancos, posibilita también la observación de características sobresalientes y particulares en bancos nacionales y sucursales o subsidiarias extranjeras. El estudio llega a la conclusión de que los cambios más substanciales de la última década en el sistema bancario del país anfitrión, fueron protagonizados por las subsidiarias extranjeras, ya que sus modelos de negocio y actividades fueron más allá de la especialización en operaciones de comercio exterior o de carácter corporativo, pero también muestra cómo los cambios en las estrategias de sus casas matrices extranjeras pueden ser perniciosos para un sistema financiero de las características del boliviano.

    Potosí, Bolivia, is the site of centuries of historic and present-day mining of the Cerro Rico, a mountain known for its rich polymetallic deposits, and was the site of large-scale Colonial era silver refining operations. In this study, the concentrations of several metal and metalloid elements were quantified in adobe brick, dirt floor, and surface dust samples from 49 houses in Potosí. Median concentrations of total mercury (Hg), lead (Pb), and arsenic (As) were significantly greater than concentrations measured in Sucre, Bolivia, a non-mining town, and exceeded US-based soil screening levels. Adobe brick samples were further analyzed for bioaccessible concentrations of trace elements using a simulated gastric fluid (GF) extraction. Median GF extractable concentrations of Hg, As, and Pb were 0.085, 13.9, and 32.2% of the total element concentration, respectively. Total and GF extractable concentrations of Hg, As, and Pb were used to estimate exposure and potential health risks to children following incidental ingestion of adobe brick particles. Risks were assessed using a range of potential ingestion rates (50-1000mg/day). Overall, the results of the risk assessment show that the majority of households sampled contained concentrations of bioaccessible Pb and As, but not Hg, that represent a potential health risk. Even at the lowest ingestion rate considered, the majority of households exceeded the risk threshold for Pb, indicating that the concentrations of this metal are of particular concern. To our knowledge, this is the first study to quantify key trace elements in building materials in adobe brick houses and the results indicate that these houses are a potential source of exposure to metals and metalloids in South American mining communities. Additional studies are needed to fully characterize personal exposure and to understand potential adverse health outcomes within the community.

    We describe the first Miocene turtle remains from Bolivia, which were collected from the late middle Miocene (13.18-13.03 Ma) of Quebrada Honda, southern Bolivia. This material includes a large scapula-acromion and fragmentary shell elements conferred to the genus Chelonoidis (Testudinidae), and a left xiphiplastron from a pleurodire or side-necked turtle, conferred to Acanthochelys (Chelidae). The occurrence of a giant tortoise and a freshwater turtle suggests that the paleoelevation of the region when the fossils were deposited was lower than has been estimated by stable isotope proxies, with a maximum elevation probably less than 1000 m. At a greater elevation, cool temperatures would have been beyond the tolerable physiological limits for these turtles and other giant ectotherm reptiles.

    In South America, cutaneous leishmaniasis is the most frequent clinical form of leishmaniasis. Bolivia is one of the countries with higher incidence, with 33 cases per 100,000 individuals, and the disease is endemic in 70% of the territory. In the last decade, the number of cases has increased, the age range has expanded, affecting children under 5 years old, and a similar frequency between men and women is found. An entomological study with CDC light traps was conducted in three localities (...

    This paper aims to clarify and understand the reasons for the current economic policy and trade between Bolivia and Brazil, the latter represented by PETROBRAS, as the year 2006. Focuses on the regulatory change in Bolivia that culminated in a period of re-nationalization of its mineral wealth as opposed to international interests, including Brazilians, and agreements entered into during the opening of the market in the country. Thus, set in the Latin American actual situation, we undertake to understand the process and its consequences for Brazil, which, even with the third largest gas reserves in the region, in the short term, it follows as an importer of this feature. To have a concrete base with foundations and analyze what happens today, we must understand the political history of Bolivia and their internal changes. So we divided the work into two parts: first, we analyze the neo liberal period, and the agreements signed with Brazil in the hydrocarbon sector, for mutual benefits. In the second part, we understand the political rise of Evo Morales and the nationalization process of national wealth and the consequent crisis that developed with the international oil companies, especially with PETROBRAS, to the final outcome on the price, production and export of gas.

    Bolivia has a large rural population, mostly composed of subsistence farmers that face natural and anthropogenic driven processes affecting their livelihoods. In order to establish sustainable management strategies, it is important to understand the factors governing landscape changes. This work explores the geomorphic imprint and effects of natural and anthropogenic driven processes on three mountain communities undergoing de-population in the Jatún Mayu watershed (Cochabamba, Bolivia). Based on satellite image interpretation, field work and household surveys, we have identified gullies and landslides as main active processes, causing land losses, affecting inter-communal roads, etc. While landslides are mostly occurring in the middle and lower section of the basin, gullies are especially affecting the upper part (especially the southern slope). Our analysis indicated that in the middle and lower part of the basin, landslides are developing in response to the Jatún Mayu incision (slopes reach a critical angle and slope failures increase). However in the upper part, where no river down-cutting is taking place, preliminary analysis indicates that past and present human interventions (over-grazing, agriculture, road construction, etc.) play a key role on driving land degradation toward the formation of gullies. Based on the comparison of high resolution images from 2004 and 2009, we determined an agricultural land loss rate of 8452 m2/year, mostly in the form of landslides. One single event swept away 0.03 km2 of agricultural lands (~13 parcels), approximately 87% of an average household property. People's main concerns are hail, frost and droughts because they cause an "immediate" loss on family incomes, but the impacts caused by landslides and gullies are not disregarded by the communities and the government. Communities are organized to set up and maintain key infrastructure such as irrigation canals and roads. They also intend to develop protective measures

    Full Text Available From the end of the nineteenth century until the middle of the twentieth, the Gran Chaco was a zone of conflict. Argentina, Bolivia and Paraguay exercised varied and competing influences in the region, reflecting the intentions of each nation to incorporate the Chaco forcibly as part of larger projects of industrialisation and colonisation. This study examines the implementation of these projects, as well as the resistance they generated in the face of the violence visited upon the inhabitants of the region, whether indigenous peoples, mestizos, or whites. From an anthropological perspective, the work also reassesses conflicts in the Chaco region as a problem in the history of inter-American relations, where non-governmental actors determine links between people and government. The article goes on to consider the national and regional contexts to conflict, in which frontiers and boundaries are further concepts and realities to be assessed.

    Desde fines del siglo XIX y hasta mediados del XX, el Gran Chaco constituyó, en procesos asimétricos ejercidos por los estados que terminaron dividiéndose su jurisdicción, la Argentina, Bolivia y Paraguay, una región de disputas, que incluyó guerras, militarización de límites, forzada incorporación en los desarrollos industrializadores y colonizadores. Este trabajo busca conocer la ejecución de aquellas políticas y las resistencias generadas, en espacios que fueron tanto de concertaciones, como de conflictos frente al poder y a la violencia ejercida sobre sus pobladores, indios, mestizos y blancos. El objetivo es también contribuir a enriquecer la historia de las relaciones interamericanas, a través de una perspectiva antropológica, en donde actores no estatales configuran vínculos entre pueblos y gobiernos, y asimismo de una mirada que se dirija simultáneamente hacia la consideración de los contextos nacionales y regionales, en donde fronteras y límites son nociones y realidades a

  5. Late Quaternary geomorphic history of a glacial landscape - new sedimentary and chronological data from the Cordillera de Cochabamba (Bolivia)

    Throughout the Central Andes, glacial landscapes have long been used for the reconstruction of Late Quaternary glaciations and landscape evolution. Much work has focused on the Andes in Peru, Chile and the Bolivian Altiplano, whereas relatively little data has been published on glaciation history in the eastern Andean ranges and slopes. Even less is known with regard to the postglacial evolution of these glacial landscapes. In the Cordillera de Cochabamba (Bolivia), local maximum advances probably peaked around 20-25 ka BP and were followed by significant readvances between ~12-16 ka BP. This generally points to temperature controlled maximum glacial advances along the humid eastern slopes of the Central Andes, which is supported by glacier-climate-modelling studies. However, most studies include only marginal information with regard to the complex geomorphic and sedimentary situation in the Cordillera de Cochabamba. Furthermore, the chronological results are afflicted with several methodological uncertainties inherent to surface exposure dating and call for application of alternative, independent age dating methods. Therefore this study aims at i) documenting and interpreting the complex glacial geomorphology of the Huara Loma valley in the Cordillera de Cochabamba (Bolivia), ii) analyzing the involved units of glacial sediments, and iii) improving the chronological framework by applying optically stimulated luminescence (OSL) and radiocarbon dating (14C). For this purpose, geomorphic mapping was combined with field documentation of sedimentary profiles. The involved sediments were subject to geochemical and mineralogical analysis in order to deduce information on their erosional and weathering histories. In addition, the interpretation of OSL ages from glacial and proglacial sediments integrated several methodological procedures with regard to sample preparation and statistical analysis of the measurements in order to increase the degree of confidence.

    The aim of this paper is to investigate the cultural landscape of the archaeological area of Tiwanaku (Bolivia) using multiscale, multispectral and multitemporal satellite data. Geospatial analysis techniques were applied to the satellite data sets in order to enhance and map traces of past human activities and perform a spatial characterization of environmental and cultural patterns. In particular, in the Tiwanaku area, the approach based on local indicators of spatial autocorrelation (LISA) applied to ASTER data allowed us to identify traces of a possible ancient hydrographic network with a clear spatial relation with the well-known moat surrounding the core of the monumental area. The same approach applied to QuickBird data, allowed us to identify numerous traces of archaeological interest, in Mollo Kontu mound, less investigated than the monumental area. Some of these traces were in perfect accordance with the results of independent studies, other were completely unknown. As a whole, the detected features, composing a geometric pattern with roughly North-South orientation, closely match those of the other residential contexts at Tiwanaku. These new insights, captured from multitemporal ASTER and QuickBird data processing, suggested new questions on the ancient landscape and provided important information for planning future field surveys and archaeogeophyical investigations.

    We present the application of a network transportation model, with capacity restrictions, to determine the minimal cost of supply of a group of markets at the Bolivia Brazil Gas Pipeline influence area, as a function of city gate price. We consider the potential of integration of pipeline transportation at the South Cone, looking forward to supply the Brazilian market. The city gate price consists of the sum of commodity price plus transportation tariffs over every gas pipeline through which the gas passes (except distribution pipelines). There is no distinction related to product quality (e.g. heating value) among suppliers, or among end uses (thermal, thermoelectric or chemical). The model is numerically solved by linear programming. Flow direction alternatives and transportation tariffs alternatives (postal and by zone) are proposed. The model allows, among other applications: identification of the lowest cost supply strategy, identification of network flow capacity bottlenecks, determination of operation and expansion marginal costs using dual solution analysis, investigation of alternative sceneries through sensibility analysis and appreciation of non-optimal solutions that might be attractive.

    Full Text Available El gobierno de Gonzalo Sánchez de Lozada (1993-1997 lideró un audaz proceso de descentralización en Bolivia en alianza con el primer vicepresidente aymara, Víctor Hugo Cárdenas. El próspero empresario minero, y conductor político del ajuste estructural de 1986, ofreció superar la época de los sufrimientos mediante la creación de cientos de municipios dotados de recursos a los que podrían acceder representantes indígenas y campesinos, hasta ahora carentes de derechos cívicos y políticos. “El gobierno del Gony y del indio” realizó a la vez una enorme privatización de cinco de los seis grandes monopolios estatales bajo el nombre de capitalizaciones. La hipótesis aquí defendida es que la descentralización y el reconocimiento indígena no fueron meras monedas de cambio para legitimar la segunda fase del ajuste macroeconómico neoliberal. Por el contrario, la arquitectura descentralizada del Estado hizo parte también del ideario programático institucional de los neoliberales, a la vez que era exigencia de los prósperos empresarios del Oriente que la necesitaban para ejercer un control estratégico sobre sus territorios.

    Agroforestry often relies on local knowledge, which is gaining recognition in development projects. However, how local knowledge can articulate with external and scientific knowledge is little known. Our study explored the use and integration of local and external knowledge in agroforestry projects in Bolivia. In 42 field visits and 62 interviews with agroforestry farmers, civil society representatives, and policymakers, we found a diverse knowledge base. We examined how local and external knowledge contribute to livelihood assets and tree and crop diversity. Projects based predominantly on external knowledge tended to promote a single combination of tree and crop species and targeted mainly financial capital, whereas projects with a local or mixed knowledge base tended to focus on food security and increased natural capital (e.g., soil restoration) and used a higher diversity of trees and crops than those with an external knowledge base. The integration of different forms of knowledge can enable farmers to better cope with new challenges emerging as a result of climate change, fluctuating market prices for cash crops, and surrounding destructive land use strategies such as uncontrolled fires and aerial fumigation with herbicides. However, many projects still tended to prioritize external knowledge and undervalue local knowledge—a tendency that has long been institutionalized in the formal educational system and in extension services. More dialogue is needed between different forms of knowledge, which can be promoted by strengthening local organizations and their networks, reforming agricultural educational institutions, and working in close interaction with policymakers.

    2013-01-01

    The dispersal of Equus into South America during the Great American Biotic Interchange (GABI) represented a major event for Pleistocene land-mammal age chronology on that continent. It has been argued that this dispersal occurred during the late Pleistocene, ∼0.125 Ma, and it defines the base of the Lujanian South American Land Mammal Age (SALMA). In this scenario, Equus dispersed during the fourth and latest recognized phase of the interchange, i.e., GABI 4. Although Equus was widely distributed in South America during the Pleistocene, only a few localities are calibrated by independent chronostratigraphic data. In this paper, new biostratigraphic evidence documents that Equus occurs from 15 superposed faunal horizons or zones throughout the Tolomosa Formation at Tarija, Bolivia. This biostratigraphic sequence is independently calibrated to occur between ∼0.99 to <0.76 Ma during the middle Pleistocene Ensenadan SALMA and coincident with GABI 3, not GABI 4. Tarija remains the only well calibrated Ensenadan locality at which Equus is found. The new biostratigraphic data presented here are unambiguous and document the earlier (pre-Lujanian) occurrence of this genus in South America. The hypothesized dispersal of the genus Equus into South America at ∼0.125 Ma is no longer supportable in light of the new biostratigraphic evidence presented here. The new data from Tarija thus have continent-wide implications for the origins and biogeography of Equus in South America as well as the calibration of GABI 3.

    Full Text Available Community-based management research is a collaborative effort between management, academics and communities in need with the specific goal of achieving social change to foster social justice. Because it is designed to promote and validate joint methods of discovery and community-based sources of knowledge, community-based management research has several unique characteristics, which may affect its execution. This article describes the process of a community-based management research project which is descriptive in nature and uses quantitative techniques to examine school efficiencies in low-income communities in a developing country – Bolivia. The article describes the partnership between a US-based university and a Bolivian not-for-profit organisation, the research context and the history of the research project, including its various phases. It focuses on the (yet unpublished process of the community-based research as opposed to its content (which has been published elsewhere. The article also makes the case that the robust partnership between the US-based university and the Bolivian NGO has been a determining factor in achieving positive results. Strengths and limitations are examined in the hope that the experience may be helpful to others conducting descriptive quantitative management research using community-engaged frameworks in cross-cultural settings. Keywords: international partnership, community-engaged scholarship, education efficiency, multicultural low-income education.

  18. Perception and Interpretation of Climate Change among Quechua Farmers of Bolivia: Indigenous Knowledge as a Resource for Adaptive Capacity

    Directory of Open Access Journals (Sweden)

    Sébastien Boillat

    2013-12-01

    Full Text Available We aim to explore how indigenous peoples observe and ascribe meaning to change. The case study involves two Quechua-speaking farmer communities from mountainous areas near Cochabamba, Bolivia. Taking climate change as a starting point, we found that, first, farmers often associate their observations of climate change with other social and environmental changes, such as value change in the community, population growth, out-migration, urbanization, and land degradation. Second, some of the people interpret change as part of a cycle, which includes a belief in the return of some characteristics of ancient or mythological times. Third, environmental change is also perceived as the expression of "extra-human intentionalities," a reaction of natural or spiritual entities that people consider living beings. On the basis of these interpretations of change and their adaptive strategies, we discuss the importance of indigenous knowledge as a component of adaptive capacity. Even in the context of living with modern science and mass media, indigenous patterns of interpreting phenomena tend to be persistent. Our results support the view that indigenous knowledge must be acknowledged as process, emphasizing ways of observing, discussing, and interpreting new information. In this case, indigenous knowledge can help address complex relationships between phenomena, and help design adaptation strategies based on experimentation and knowledge coproduction.

    Chagas disease, which is caused by the parasite Trypanosoma cruzi, is transmitted to humans by blood-sucking bugs (Triatominae). Eratyrus mucronatus is a well-dispersed triatomine species, found sometimes in dwellings. In the Apolo region of Bolivia, people continue to complain of bites by this bug despite five years of chemical control. For the first time, the domiciliation process of E. mucronatus was evaluated in a zone treated by insecticide, and it was compared with a previous situation 14 years ago. Both an entomological and a serological study were carried out: 152 dwellings were visited and 491 blood samples were analyzed with Stat-Pack and ELISA tests. In 34 dwellings (23% of the total visited dwellings), 160 triatomines of all stages were collected belonging to two species, E. mucronatus (98% of the capture) and Panstrongylus geniculatus. A domiciliation of E. mucronatus is demonstrated, particularly in the peridomicile. Bugs were captured more frequently in bedrooms in the intradomicile, and in curahuas (boundary walls in rammed mud) in the peridomicile. A P. geniculatus adult was found infected with T. cruzi. No evidence of a local vectorial transmission was found. In particular, the limited effect of the insecticide on the presence of E. mucronatus and the role of the curahuas as a source of intrusion/domiciliation process are discussed.

In the border region, the incidence rate (49.1/100,000 inhabitants), mortality rate (4.0/100,000 inhabitants), and treatment dropout rate (11.3%) were 1.6, 1.8, and 1.5 times higher than in the non-border region. Among indigenous individuals in the border region, the rates for incidence (253.4/100,000 inhabitants), mortality (11.6/100,000 inhabitants), and HIV/TB co-infection (1.9/100,000 inhabitants) were 6.4, 3.2, and 1.9 times higher than in non-indigenous individuals in this region. Living in the border regions was inversely associated with HIV/TB co-infection. Indigenous ethnicity was associated statistically with not abandoning TB treatment. The study concludes that the population residing in these municipalities along the border is exposed to high risk of pulmonary TB and TB mortality and treatment dropout, thus requiring special health surveillance interventions.

    Surface exposure dating (SED) is an innovative tool already being widely applied for moraine dating and for Late Quaternary glacier and climate reconstruction. Here we present exposure ages of 28 boulders from the Cordillera Real and the Cordillera Cochabamba, Bolivia. Our results indicate that the local Last Glacial Maximum (LGM) in the Eastern Cordilleras occurred at ~22-25 ka and was thus synchronous to the global temperature minimum. We were also able to date several Late Glacial moraines to ~11-13 ka, which likely document lower temperatures and increased precipitation ("Coipasa" humid phase). Additionally, we recognize the existence of older Late Glacial moraines re-calculated to ~15 ka from published cosmogenic nuclide data. Those may coincide with the cold Heinrich 1 event in the North Atlantic region and the pronounced "Tauca" humid phase. We conclude that (i) exposure ages in the tropical Andes may have been overestimated so far due to methodological uncertainties, and (ii) although precipitation plays an important role for glacier mass balances in the tropical Andes, it becomes the dominant forcing for glaciation only in the drier and thus more precipitation-sensitive regions farther west and south.

    Full Text Available In this study we compared the utility of two molecular biology techniques, cloning of the mitochondrial 12S ribosomal RNA gene and hydrolysis probe-based qPCR, to identify blood meal sources of sylvatic Chagas disease insect vectors collected with live-bait mouse traps (also known as Noireau traps. Fourteen T. guasayana were collected from six georeferenced trap locations in the Andean highlands of the department of Chuquisaca, Bolivia.We detected four blood meals sources with the cloning assay: seven samples were positive for human (Homo sapiens, five for chicken (Gallus gallus and unicolored blackbird (Agelasticus cyanopus, and one for opossum (Monodelphis domestica. Using the qPCR assay we detected chicken (13 vectors, and human (14 vectors blood meals as well as an additional blood meal source, Canis sp. (4 vectors.We show that cloning of 12S PCR products, which avoids bias associated with developing primers based on a priori knowledge, detected blood meal sources not previously considered and that species-specific qPCR is more sensitive. All samples identified as positive for a specific blood meal source by the cloning assay were also positive by qPCR. However, not all samples positive by qPCR were positive by cloning. We show the power of combining the cloning assay with the highly sensitive hydrolysis probe-based qPCR assay provides a more complete picture of blood meal sources for insect disease vectors.

    Full Text Available Acid mine drainage (AMD is a worldwide environmental problem. The passive co-treatment of AMD with municipal waste water (MWW is a cost effective approach that uses nutrients in MWW in order to treat high concentrations of metals and sulfate found in AMD. Cerro Rico de Potosí in Bolivia is one of the biggest mining cities in the world, and it is constantly facing problems with AMD. The goal of this study was to determine the reaction rates of Al, Fe, Mn, Zn, and other metals found in an AMD discharge from Cerro Rico by a three-stage reactor system. The AMD had a pH of 3.58 and acidity of 1080 mg/L as CaCO3 equivalent containing 12, 68, 17 and 550 mg/L of dissolved Al, Fe, Mn, and Zn respectively. The reaction rates of Al, Fe, Mn, and Zn were 1.43, 2.09, 0.01, and 0.10 d-1, respectively.

    Full Text Available El gobierno de Gonzalo Sánchez de Lozada (1993-1997 lideró un audaz proceso de descentralización en Bolivia en alianza con el primer vicepresidente aymara, Víctor Hugo Cárdenas. El próspero empresario minero, y conductor político del ajuste estructural de 1986, ofreció superar la época de los sufrimientos mediante la creación de cientos de municipios dotados de recursos a los que podrían acceder representantes indígenas y campesinos, hasta ahora carentes de derechos cívicos y políticos. "El gobierno del Gony y del indio" realizó a la vez una enorme privatización de cinco de los seis grandes monopolios estatales bajo el nombre de capitalizaciones. La hipótesis aquí defendida es que la descentralización y el reconocimiento indígena no fueron meras monedas de cambio para legitimar la segunda fase del ajuste macroeconómico neoliberal. Por el contrario, la arquitectura descentralizada del Estado hizo parte también del ideario programático institucional de los neo-liberales, a la vez que era exigencia de los prósperos empresarios del Oriente que la necesitaban para ejercer un control estratégico sobre sus territorios.

    Full Text Available This article studies the history of indigenous education in Bolivia from two fundamental aspects: the education which can be considered as built «from below», that is, from the very same indigenous peoples or nations, and the one which resulted, in different historical times, from governmental policies. The latter addressed, in one way or another, the «education of the Indian», in the framework of the «educational reforms». The hypothesis that is being defended is that today both tendencies can meet and converge. This is due to the fact that indigenous nations of Aymara, Quechua and Guarani, as well as peoples of the lowlands of Bolivia, have reached an important direct representation in the institutions of the State.En este artículo se estudia la historia de la educación indígena en Bolivia desde dos vertientes fundamentales: la educación que puede considerarse como construida «desde abajo», es decir, desde los propios pueblos o naciones indígenas, y la que surgió en distintos momentos históricos a partir de políticas gubernamentales que en el marco de «reformas educativas» abordaron de una u otra manera la «educación del indio». La hipótesis que se defiende es que hoy pueden confluir y/o articularse la perspectiva «desde abajo» y la estatal o gubernamental, en la medida en que las naciones indígenas de aymaras, quechuas, guaraníes y pueblos de las tierras bajas de Bolivia han alcanzado una importante representación directa en las instituciones del Estado.

    Full Text Available RESUMEN: Con la reforma constitucional de 1994, Bolivia dejó atrás el paradigma del Estado liberal y etnocéntrico, para asumir otro de carácter multicultural que se caracteriza por el reconocimiento de la diversidad etnocultural. A partir de la misma, también se reconoció con carácter limitado, la vigencia y validez del Derecho Consuetudinario Indígena como mecanismo legítimo y alternativo de resolución de conflictos. Al igual que para obtener dicho reconocimiento, ha sido necesario esgrimir argumentos y canalizar demandas a través de los movimientos indígenas, ahora corresponde cimentar nuevos fundamentos que destierren algunos mitos sobre la naturaleza de la justicia comunitaria, cuya complejidad ha hecho que el Estado retrase su tratamiento, siendo su reglamentación un tema pendiente en la agenda política.ABSTRACT: With the constitutional reform of 1994, Bolivia, left behind the paradigm of the liberal and ethno-centric State, to assume a new multicultural character that results from the constitutional recognition of ethno-cultural diversity. The reform also acknowledged, albeit in a limited form, the use and validity of community justice as a legitimate and alternative mechanism of conflict resolution. The indigenous movement played a key role in putting forward these demands, it is now necessary to dispel some of the misplaced myths that exist concerning community justice. Instead, we need to address the complexity of the issue, a complexity which to date has contributed to delaying the development of the corresponding regulatory legislative framework. This article examines through an empirical analysis the diversity of community justice in Bolivia.

  10. Social differentiation and embodied dispositions: a qualitative study of maternal care-seeking behaviour for near-miss morbidity in Bolivia

    2009-07-01

    Full Text Available Abstract Background Use of maternal health care in low-income countries has been associated with several socioeconomic and demographic factors, although contextual analyses of the latter have been few. A previous study showed that 75% of women with severe obstetric morbidity (near-miss identified at hospitals in La Paz, Bolivia were in critical conditions upon arrival, underscoring the significance of pre-hospital barriers also in this setting with free and accessible maternal health care. The present study explores how health care-seeking behaviour for near-miss morbidity is conditioned in La Paz, Bolivia. Methods Thematic interviews with 30 women with a near-miss event upon arrival at hospital. Near-miss was defined based on clinical and management criteria. Modified analytic induction was applied in the analysis that was further influenced by theoretical views that care-seeking behaviour is formed by predisposing characteristics, enabling factors, and perceived need, as well as by socially shaped habitual behaviours. Results The self-perception of being fundamentally separated from "others", meaning those who utilise health care, was typical for women who customarily delivered at home and who delayed seeking medical assistance for obstetric emergencies. Other explanations given by these women were distrust of authority, mistreatment by staff, such as not being kept informed about their condition or the course of their treatment, all of which reinforced their dissociation from the health-care system. Conclusion The findings illustrate health care-seeking behaviour as a practise that is substantially conditioned by social differentiation. Social marginalization and the role health institutions play in shaping care-seeking behaviour have been de-emphasised by focusing solely on endogenous cultural factors in Bolivia.

    Habitat structure and anthropogenic disturbance are known to affect primate diversity and abundance. However, researchers have focused on lowland rain forests, whereas endangered deciduous forests have been neglected. We aimed to investigate the relationships between primate diversity and abundance and habitat parameters in 10 deciduous forest fragments southeast of Santa Cruz, Bolivia. We obtained primate data via line-transect surveys and visual and acoustic observations. In addition, we assessed the vegetation structure (canopy height, understory density), size, isolation time, and surrounding forest area of the fragments. We interpreted our results in the context of the historical distribution data for primates in the area before fragmentation and interviews with local people. We detected 5 of the 8 historically observed primate species: Alouatta caraya, Aotus azarae boliviensis, Callithrix melanura, Callicebus donacophilus, and Cebus libidinosus juruanus. Total species number and detection rates decreased with understory density. Detection rates also negatively correlated with forest areas in the surroundings of a fragment, which may be due to variables not assessed, i.e., fragment shape, distance to nearest town. Observations for Alouatta and Aotus were too few to conduct further statistics. Cebus and Callicebus were present in 90% and 70% of the sites, respectively, and their density did not correlate with any of the habitat variables assessed, signaling high ecological plasticity and adaptability to anthropogenic impact in these species. Detections of Callithrix were higher in areas with low forest strata. Our study provides baseline data for future fragmentation studies in Neotropical dry deciduous forests and sets a base for specific conservation measures.

    2015-12-01

    We present a catalog of full seismic moment tensors for 63 events from Uturuncu volcano in Bolivia. The events were recorded during 2011-2012 in the PLUTONS seismic array of 24 broadband stations. Most events had magnitudes between 0.5 and 2.0 and did not generate discernible surface waves; the largest event was Mw 2.8. For each event we computed the misfit between observed and synthetic waveforms, and we also used first-motion polarity measurements to reduce the number of possible solutions. Each moment tensor solution was obtained using a grid search over the six-dimensional space of moment tensors. For each event we characterize the variation of moment tensor source type by plotting the misfit function in eigenvalue space, represented by a lune. We plot the optimal solutions for the 63 events on the lune in order to identify three subsets of the catalog: (1) a set of isotropic events, (2) a set of tensional crack events, and (3) a swarm of events southeast of the volcanic center that appear to be double couples. The occurrence of positively isotropic events is consistent with other published results from volcanic and geothermal regions. Several of these previous results, as well as our results, cannot be interpreted within the context of either an oblique opening crack or a crack-plus-double-couple model; instead they require a multiple-process source model. Our study emphasizes the importance of characterizing uncertainties for full moment tensors, and it provides strong support for isotropic events at Uturuncu volcano.

    Bolivia has a total of 47 species of Psittacidae, seven of which have been identified in our study site, the semiarid Gran Chaco of the Isoso. One species, the blue-fronted parrot (Amazona aestiva), is frequently captured by local Isoseño Guaraní Indians for exploitation on the national and international market. These birds are often temporarily housed in small villages under unhygienic conditions with poultry and other domestic species. On occasion, these parrots escape back to the wild. Additionally, many of these birds are kept as pets or are used to lure wild. parrots within slingshot range for subsequent capture. In this study, we evaluated the health status, including the level of exposure to selected infectious agents, in the wild-caught captive birds and free-ranging birds. Physical examinations were performed, and blood was collected, from 54 live birds (20 captive and 34 free-ranging). Feces were collected from 15 birds (seven captive and eight free-ranging). Necropsies were also performed on four recently dead wild-caught birds. On serologic testing, no birds were found to have antibodies to avian influenza virus, Chlamydophila psittaci, infectious bronchitis virus, infectious bursal disease virus, infectious laryngotracheitis virus, Marek's disease virus, paramyxovirus-1, paramyxovirus-2, paramyxovirus-3, polyomavirus, eastern equine encephalitis virus, western equine encephalitis virus, or Venezuelan equine encephalitis virus. Positive antibody titers were found for psittacine herpesvirus (8/44, 18.2%), Aspergillus spp. (3/51, 5.9%), and Salmonella pullorum (33/49, 67.3%). All three of the birds that tested antibody positive for Aspergillus spp. were captive, whereas six of the eight and 15 of the 33 birds that tested positive for psittacine herpesvirus and S. pullorum, respectively, were wild.

    Full Text Available BACKGROUND: Chagas disease, caused by the flagellate parasite Trypanosoma cruzi affects 8-10 million people in Latin America. The mechanisms that underlie the development of complications of chronic Chagas disease, characterized primarily by pathology of the heart and digestive system, are not currently understood. To identify possible host genetic factors that may influence the clinical course of Chagas disease, Human Leucocyte Antigen (HLA regional gene polymorphism was analyzed in patients presenting with differing clinical symptoms. METHODOLOGY: Two hundred and twenty nine chronic Chagas disease patients in Santa Cruz, Bolivia, were examined by serological tests, electrocardiogram (ECG, and Barium enema colon X-ray. 31.4% of the examinees showed ECG alterations, 15.7% megacolon and 58.1% showed neither of them. A further 62 seropositive megacolon patients who had undergone colonectomy due to acute abdomen were recruited. We analyzed their HLA genetic polymorphisms (HLA-A, HLA-B, MICA, MICB, DRB1 and TNF-alpha promoter region mainly through Sequence based and LABType SSO typing test using LUMINEX Technology. PRINCIPAL FINDINGS: The frequencies of HLA-DRB1*01 and HLA-B*14:02 were significantly lower in patients suffering from megacolon as well as in those with ECG alteration and/or megacolon compared with a group of patients with indeterminate symptoms. The DRB1*0102, B*1402 and MICA*011 alleles were in strong Linkage Disequilibrium (LD, and the HLA-DRB1*01-B*14-MICA*011 haplotype was associated with resistance against chronic Chagas disease. CONCLUSIONS: This is the first report of HLA haplotype association with resistance to chronic Chagas disease.

    Full Text Available Recent results of presidential elections in Latin America suggest a turn to the left in various countries. In Bolivia, such a movement includes the victory of an Aymara Indian who is also a leader of coca farmers. The article proposes an interpretation of this event, describes and discusses the main actions of the new government, stressing the reactions they provoked, and explores the class, ethnic and territorial dimensions of the resulting conflicts. The regional aspects of the fights, seen in connection with the country's historical regionalism, are highlighted and their basic conditions are investigated.

    2008-09-01

    The article begins by describing the difficult living conditions of many people in the hill slopes (laderas) of La Paz, Bolivia, demonstrating that they are exposed to a combination of natural and social hazards. It shows that residents, community leaders and city planners tend to underestimate or deny risk, with important consequences for risk management, such as a failure to raise risk awareness. The article then proposes some hypotheses to explain risk perceptions in La Paz, discarding the usual single-approach interpretations and suggesting instead more nuanced theoretical explanations to account for why people build their homes in such hazardous environments.

    Full Text Available From 2000 to 2010, Bolivia and Peru underwent similar processes of political decentralization toward the meso level of the government. Three elections later in Peru and two in Bolivia, the ability of national political parties to articulate interests differs markedly between the two countries. Peru tends toward fragmentation with national parties incapable of participating or successfully competing in subnational elections, while in Bolivia, the Movimiento al Socialismo (MAS – and other parties to a lesser extent – are increasingly capable of participating and winning subnational offices. This paper argues that, despite having undergone very similar institutional reforms, the difference between the cases can largely be explained by two “society-side” variables: the caliber of the political ideas in debate and political social density. The substantive quality of ideas in debate and a greater political social density have been crucial to the Bolivian trend, while their absence has lessened the possibility of anything similar occurring in Peru. In general terms, the article sheds light on the social conditions that favor party-building in a context of decentralization reform.Entre el 2000 y el 2010, Bolivia y Perú emprendieron procesos similares de descentralización política hacia el nivel meso de gobierno. Después de tres elecciones en Perú y dos en Bolivia, la capacidad de los partidos políticos nacionales para articular intereses difiere sustantivamente en ambos países. El Perú tiende a la fragmentación pues los partidos nacionales son incapaces de participar con éxito en los niveles sub-nacionales de competencia política, mientras que en Bolivia el Movimiento al Socialismo (MAS – y, en menor medida, otros partidos - incrementan su capacidad de participar y conseguir victorias en los niveles sub-nacionales.

    Accurate estimates of global carbon emissions are critical for understanding global warming. This paper estimates net carbon emissions from land use change in Bolivia during the periods 1990-2000 and 2000-2010 using a model that takes into account deforestation, forest degradation, forest regrowth, gradual carbon decomposition and accumulation, as well as heterogeneity in both above ground and below ground carbon contents at the 10 by 10 km grid level. The approach permits detailed maps of net emissions by region and type of land cover. We estimate that net CO2 emissions from land use change in Bolivia increased from about 65 million tons per year during 1990-2000 to about 93 million tons per year during 2000-2010, while CO2 emissions per capita and per unit of GDP have remained fairly stable over the sample period. If we allow for estimated biomass increases in mature forests, net CO2 emissions drop to close to zero. Finally, we find these results are robust to alternative methods of calculating emissions.

    2009-12-01

    Full Text Available Background Selective vertical programs prevailed over comprehensive primary health care in Latin America. In Bolivia and Ecuador, socialist governments intend to redirect health policy. We outline both countries’ health system’s features after reform, explore their efforts to rebuild primary health care, identify and explain policy gaps, and offer considerations for improvement. Methods Qualitative document analysis. Findings Earlier reform left Bolivia’s and Ecuador’s population in bad health, with limited access to a fragmented health system. Today, both countries focus their policy on household and community-based promotion and prevention. The negative effects on access to care of decentralization, dual employment, vertical programming and targeting are largely left unattended. Neglecting care is understandable in the light of particular interpretations of social medicine and social determinants, international policy pressures, reliance on external funding and institutional inertia. Current policy choices preserve key elements of selective care and consolidate commodification. It might not improve health and worsen poverty. Interpretation Care can be considered as a social determinant on its own. Key to the accomplishment of primary care is an integrated application of family medicine, taking advantage of individual care as one of the ways to act on social determinants. It deserves a central place on the policy-makers’ priority list, in Bolivia and Ecuador as elsewhere.

The system has the common characteristics with South American countries;and they have divided the mining activities into basic mining activities and mining auxiliary activities, which have been subject to different laws. At the same time, national mining companies have directly involved in mining management which epitomized the nationalism over mineral resources. In terms of mineral right, there is no mineral exploration right or exploitation right in Bolivia.%  玻利维亚矿业管制体制具有南美国家共同的特点,将矿业活动分为基础矿业活动与矿业辅助活动,并适用不同的法律,同时国家矿业公司直接参与矿业管理,是矿产资源民族主义的集中体现。玻利维亚矿业权没有探矿权、采矿权之分,是其有别于大多数国家的重要特点。相对于其矿业开发环境保护的相关规定,玻利维亚矿业税费总体上比较简单,集中体现在矿业权特许费上。

    In South America, cutaneous leishmaniasis is the most frequent clinical form of leishmaniasis. Bolivia is one of the countries with higher incidence, with 33 cases per 100,000 individuals, and the disease is endemic in 70% of the territory. In the last decade, the number of cases has increased, the age range has expanded, affecting children under 5 years old, and a similar frequency between men and women is found. An entomological study with CDC light traps was conducted in three localities (Chipiriri, Santa Elena and Pedro Domingo Murillo) of the municipality of Villa Tunari, one of the main towns in the Chapare province (Department of Cochabamba, Bolivia). A total of 16 specimens belonging to 6 species of the genus Lutzomyia were captured: Lu. aragaoi, Lu. andersoni, Lu. antunesi, Lu. shawi, Lu. yuilli yuilli and Lu. auraensis. Our results showed the presence of two incriminated vectors of leishmaniasis in an urbanized area and in the intradomicile. More entomological studies are required in the Chapare province to confirm the role of vector sand flies, the intradomiciliary transmission of the disease and the presence of autochthonous cases of cutaneous leishmaniasis.

    Full Text Available Abstract: Challenges and perspectives of water governance and integrated water resource management in BoliviaBolivia is not only highly affected by social and political instability, but also by erosion and climate change and an indiscriminate and vast exploitation of its natural resources. The new policy structure seeks to establish a broad consensus on better water governance relying on a participatory democracy approach and the commitment to indicators for sustainable development. The creation of a Water Ministry in 2006, which emerged from the water riots against privatization of water rights and sanitation services in 2000, can be interpreted as a clear sign for more integration of social movements and civil organizations. But at the present these organizations seemed to be marginalized from the decision-making process, and government and public institutions are confronting a complex situation of weakened legitimacy. The present paper offers an insight on the ongoing process, including the challenges and obstacles for the implementation of a new water policy and local integrated water management systems. The reflections consider the official legal framework and a policy analysis in order to illustrate the conflictive schemes in different regions and localities. The final aim is to indicate the gaps between the official discourse and local realities for water governance and to indicate some recommendations for a more coherent public-civic action in water governance, control and transparency. Resumen:Bolivia no solo es afectada por una inestabilidad social y política, sino también por erosión, efectos del cambio climático y una explotación indiscriminada de los recursos naturales.

    2007-06-01

    Full Text Available Abstract Background The Andean valleys of Bolivia are the only reported location of sylvatic Triatoma infestans, the main vector of Chagas disease in this country, and the high human prevalence of Trypanosoma cruzi infection in this region is hypothesized to result from the ability of vectors to persist in domestic, peri-domestic, and sylvatic environments. Determination of the rate of Trypanosoma infection in its triatomine vectors is an important element in programs directed at reducing human infections. Traditionally, T. cruzi has been detected in insect vectors by direct microscopic examination of extruded feces, or dissection and analysis of the entire bug. Although this technique has proven to be useful, several drawbacks related to its sensitivity especially in the case of small instars and applicability to large numbers of insects and dead specimens have motivated researchers to look for a molecular assay based on the polymerase chain reaction (PCR as an alternative for parasitic detection of T. cruzi infection in vectors. In the work presented here, we have compared a PCR assay and direct microscopic observation for diagnosis of T. cruzi infection in T. infestans collected in the field from five localities and four habitats in Chuquisaca, Bolivia. The efficacy of the methods was compared across nymphal stages, localities and habitats. Methods We examined 152 nymph and adult T. infestans collected from rural areas in the department of Chuquisaca, Bolivia. For microscopic observation, a few drops of rectal content obtained by abdominal extrusion were diluted with saline solution and compressed between a slide and a cover slip. The presence of motile parasites in 50 microscopic fields was registered using 400× magnification. For the molecular analysis, dissection of the posterior part of the abdomen of each insect followed by DNA extraction and PCR amplification was performed using the TCZ1 (5' – CGA GCT CTT GCC CAC ACG GGT GCT – 3

    Background Solar drinking water disinfection (SODIS) is a low-cost, point-of-use water purification method that has been disseminated globally. Laboratory studies suggest that SODIS is highly efficacious in inactivating waterborne pathogens. Previous field studies provided limited evidence for its effectiveness in reducing diarrhoea. Methods and Findings We conducted a cluster-randomized controlled trial in 22 rural communities in Bolivia to evaluate the effect of SODIS in reducing diarrhoea among children under the age of 5 y. A local nongovernmental organisation conducted a standardised interactive SODIS-promotion campaign in 11 communities targeting households, communities, and primary schools. Mothers completed a daily child health diary for 1 y. Within the intervention arm 225 households (376 children) were trained to expose water-filled polyethyleneteraphtalate bottles to sunlight. Eleven communities (200 households, 349 children) served as a control. We recorded 166,971 person-days of observation during the trial representing 79.9% and 78.9% of the total possible person-days of child observation in intervention and control arms, respectively. Mean compliance with SODIS was 32.1%. The reported incidence rate of gastrointestinal illness in children in the intervention arm was 3.6 compared to 4.3 episodes/year at risk in the control arm. The relative rate of diarrhoea adjusted for intracluster correlation was 0.81 (95% confidence interval 0.59–1.12). The median length of diarrhoea was 3 d in both groups. Conclusions Despite an extensive SODIS promotion campaign we found only moderate compliance with the intervention and no strong evidence for a substantive reduction in diarrhoea among children. These results suggest that there is a need for better evidence of how the well-established laboratory efficacy of this home-based water treatment method translates into field effectiveness under various cultural settings and intervention intensities.

Parades and Wiphalas (the Indigenous Peoples’ flag and new national emblem since 2009 have become symbols of the schools and form the backbone of the behaviors and values that the school institution seeks to transmit to its students.

    2008-06-01

    Latitudinal changes in topography, climate, and thrust belt geometry in the central Andes have led to conflicting hypotheses that climate or tectonics exert a first-order control on orogen evolution. The relative roles of climate and tectonics in the evolution of the Andean orogen are difficult to quantify because of a lack of detailed observations for both the long-term deformation and erosion history of the Andean fold-thrust belt. We contribute to the resolution of this problem by presenting a sequentially restored, balanced cross section based on new mapping across the northern Bolivia portion of the thrust belt (15-17°S). The timing and magnitude of exhumation across the cross section are determined by synthesizing 10 new and ˜70 previously published mineral cooling ages. Once balanced and restored, the section was sequentially forward modeled using stratigraphic and cooling age constraints. Results indicate the Eastern Cordillera (EC) records the highest magnitudes of shortening (123 km or 55%). The Interandean zone (IA) has shortened 48 km or 30%. In both the EC and IA individual thrust sheets are tightly folded and have minor offsets of 1-5 km. The Subandes (SA) has multiple levels of detachments allowing for thrust sheets with relatively large offsets (6-17 km). Total shortening in the SA is 66 km or 40%. Total magnitude of shortening for the entire fold-thrust belt in this region is 276 km (40%). New apatite and zircon fission track cooling ages in conjunction with published ages indicate two phases of rapid exhumation; an earlier phase from ˜40 to 25 Ma in the EC and one prior to ˜25 Ma in the IA, followed by distributed exhumation of the entire fold-thrust belt from ˜15-0 Ma. Combined exhumation estimates from the balanced cross section and thermochronology suggest ˜9-11 km of exhumation in the EC, ˜5-9 km in the IA, and ˜3-4 km in the SA. Long-term shortening rates are 7 mm/a for the EC and IA and 4-8 mm/a for the SA. The SA shortening rates

    Full Text Available El bosque tucumano-boliviano, en su sector correspondiente a Bolivia, ha comenzado a ser conocido con mayor detalle en los últimos años. Sin embargo, los estudios realizados han tenido un carácter más cualitativo o se han realizado en superficies pequeñas (0,1 ha; además, la biogeografía de sus zonas más bajas no está del todo clara. Por otro lado, algunos aspectos ecológicos, como los referidos a patrones espaciales de los árboles, no han sido nunca abordados. Nosotros realizamos el estudio de una hectárea de bosque tucumano-boliviano a 700-950 m, y mapeamos todos los árboles y lianas con DAP ¿10 cm a fin de caracterizar cuantitativamente un área representativa de este bosque. El propósito fue conocer su composición, abundancia y estructura. Realizamos el primer estudio de patrones espaciales para este tipo de bosque en Bolivia. Registramos 591 individuos agrupados en 31 familias, 47 géneros y 57 especies. Seis especies fueron las más abundantes: Urera caracasana, Trichilia clausenii, Piper tucumanum, Diatenopteryx sorbifolia, Chrysophyllum gonocarpum y Cupania vernalis. El bosque estudiado puede considerarse parte del bosque tucumano-boliviano más que del Arco Pleistocénico. El área basal total fue de 29.4 m2/ha. La presencia de lianas fue relativamente baja, lo que indica que se trata de un bosque relativamente poco perturbado. Se trata de un lugar diverso. La riqueza específica resultó comparable a la de los bosques secos de Madidi (La Paz, Bolivia, y superior a la del tucumano-boliviano en el lado argentino, y fue estimada en 74 especies de árboles. La diversidad (3,5 índice Shannon-Wiener es tan alta como la de muchos bosques más tropicales, e incluso algunos amazónicos. Encontramos un patrón espacial aleatorio en los individuos de la comunidad, y la mayoría de las especies presentó agregación a alguna escala espacial.

El artículo es parte de los resultados del Proyecto LIAS (Linguistic Identity and Attitudes in Spanish-speaking Latin America, financiado por El Consejo Noruego de Investigación (RCN. La recolección de los datos se realizó en La Paz, entrevistando a una muestra de 400 informantes estratificada con las variables de edad, sexo y nivel socioeconómico. En análisis muestra, en general, una actitud positiva de parte de los hablantes bolivianos hacia su propia variedad de habla española. Se concluye también que los entrevistados son conscientes de que existen diversas variantes del español, no solamente dentro de su país, sino también fuera de este, las cuales reconocen como diferentes entre sí y las que no perciben como incorrectas o correctas, mejores o peores que otras. Abstract This article analyzes the linguistic attitudes of native Spanish speakers from La Paz, towards Spanish spoken in Bolivia and in the other Spanish-speaking countries. It is a result of the LIAS-Project (Linguistic Identity and attitudes in Spanish-speaking Latin America, funded by The Research Council of Norway (RCN. The data were gathered in La Paz, interviewing a stratified sample of 400 respondents based on the variables of age, sex and socioeconomic status. The analysis shows, in general, that Spanish speakers in Bolivia have a positive attitude towards their own variety of the language. It is also shown that the interviewees are aware that there are other varieties of the Spanish language, not only in their country, but also in the other Spanish-speaking countries. They do not characterize these varieties as incorrect or correct, better or worse, but only consider them as different from the others.

  8. Imaging the transition from flat to normal subduction: variations in the structure of the Nazca slab and upper mantle under southern Peru and northwestern Bolivia

    Two arrays of broad-band seismic stations were deployed in the north central Andes between 8° and 21°S, the CAUGHT array over the normally subducting slab in northwestern Bolivia and southern Peru, and the PULSE array over the southern part of the Peruvian flat slab where the Nazca Ridge is subducting under South America. We apply finite frequency teleseismic P- and S-wave tomography to data from these arrays to investigate the subducting Nazca plate and the surrounding mantle in this region where the subduction angle changes from flat north of 14°S to normally dipping in the south. We present new constraints on the location and geometry of the Nazca slab under southern Peru and northwestern Bolivia from 95 to 660 km depth. Our tomographic images show that the Peruvian flat slab extends further inland than previously proposed along the projection of the Nazca Ridge. Once the slab re-steepens inboard of the flat slab region, the Nazca slab dips very steeply (˜70°) from about 150 km depth to 410 km depth. Below this the slab thickens and deforms in the mantle transition zone. We tentatively propose a ridge-parallel slab tear along the north edge of the Nazca Ridge between 130 and 350 km depth based on the offset between the slab anomaly north of the ridge and the location of the re-steepened Nazca slab inboard of the flat slab region, although additional work is needed to confirm the existence of this feature. The subslab mantle directly below the inboard projection of the Nazca Ridge is characterized by a prominent low-velocity anomaly. South of the Peruvian flat slab, fast anomalies are imaged in an area confined to the Eastern Cordillera and bounded to the east by well-resolved low-velocity anomalies. These low-velocity anomalies at depths greater than 100 km suggest that thick mantle lithosphere associated with underthrusting of cratonic crust from the east is not present.

    The goal of this study was to identify the degree of knowledge of students and health educators on licit and illicit drugs, related to the type, classification, action, mechanisms damages, consequences and adverse effects, besides use and consumption. A cross-sectional methodological design was used, with a sample of 172 students, professors and residents in medicine and nursing at Universidad Mayor de San Andrés (UMSA), Bolivia. The results reveal weak knowledge on the classification of psychotropic substances according to structure, chemical property and effects for health, highlighting significant difference with knowledge on licit and illicit drugs use, with high percentages. In conclusion, there is lack of knowledge in all groups studied on licit and illicit drugs regarding the consequences and adverse effects. This confirms the need to improve teaching on this content in health schools.

    This paper reviews a new four billion dollar arrangement which would start a major gas network between Brazil and Bolivia. The proposed 2,200 mile long, 28 and 14 inch pipeline network would connect Bolivian reserves with the undeserved markets of southern Brazil. The paper briefly reviews the economic involvement and impacts on both countries and the current market for natural gas in Brazil. Because most of Brazil's energy is currently from hydroelectric power or petroleum, the new distribution network will have dramatic effects on industries which need this high-grade fuel source for operation. Financing of this project will be by Petrobras and 49 percent through stock options.

    There are close to 1 million people in the world who are alive simply because they have access to one form or another of renal replacement therapy (RRT). Ninety percent live in high-income countries. Little is known of prevalence and incidence of chronic kidney disease and of end-stage renal disease (ESRD) in middle-income and low-income countries, where the use of RRT is scarce or nonexistent. However, no intervention is undertaken, these people will experience progression to ESRD and death from uremia, because RRT is out of reach for them. These are the individuals for whom efforts should be focused to prevent or delay progression toward ESRD. In 1992, the Mario Negri Institute for Pharmacological Research in Bergamo, Italy, with the cooperation of the young doctors of the Ospedale Giovanni XXIII in La Paz (Bolivia), activated a specific project titled "El Proyecto de Enfermedades Renales en Bolivia" (The Project for Renal Diseases in Bolivia). The project sought to demonstrate that in emerging countries the best strategies against renal disease are prevention and early detection. After proper training of local personnel at the Clinical Research Center "Aldo e Cele Dacco" of the Mario Negri Institute in Bergamo, Italy, an educational campaign titled "First Clinical and Epidemiological Program of Renal Diseases"-under the auspices of the Renal Sister Center Program of the International Society of Nephrology-was conducted in 3 selected areas of Bolivia, including tropical, valley, and plains areas. The goal was to define the frequency of asymptomatic renal disease in these areas by screening a large population of patients at relatively low costs. The screening was formally performed at first-level health centers (Unidad de Salud). Participants were instructed to void a clean urine specimen, and a dipstick test was performed. Patients with positive urinalysis were enrolled in a follow-up program with subsequent laboratory and clinical checks. The study was conducted

    "In the sixteenth and seventeenth centuries Spanish officials and members of the Catholic church created a series of race-based caste terms designed to identify and categorize the peoples of mixed ancestry. The Spanish American caste system relied on the assumed ability of a census-taker or priest to define the blood lines of an individual based on skin color and physical characteristics. However, the demographic knowledge created from the caste system was imprecise, and changed over time.... There were also long-term shifts in the meaning of terms and the definitions of status caused by socioeconomic changes. An example is the rapid rate of apparent mestizoization in the...indigenous communities of the Valle Bajo of Cochabamba, Bolivia. The rapid increase in the number of mestizos was related to changing definitions of the status and identity of indigenous peoples, and was not strictly caused by racial mixture."

    We conducted a cross-sectional study of Chagas disease in five endemic areas in Argentina, Bolivia, Honduras, and México to estimate the prevalence of Trypanosoma cruzi-specific antibodies in pregnant women, and to assess the use of a rapid test (Chagas Stat-Pak) to screen for T. cruzi infection at the time of delivery. The prevalence of antibodies to T. cruzi measured by enzyme-linked immunosorbent assay (ELISA) in maternal blood was 5.5% (a range of 0.8-28.8% among the countries) in 2,495 women enrolled. Compared with ELISA in maternal blood samples, the Chagas Stat-Pak rapid test sensitivity and specificity in umbilical cord blood were 94.6% and 99.0%, respectively. These results show the ability for a rapid determination of the presence of T. cruzi-specific antibodies in umbilical cord blood as a pragmatic strategy to screen for infection in pregnant women.

Of the 71 children born with congenital Chagas, only 47,8 % present/display some type of alteration or of development(Apgar to 1 minute low, BPN, prematuridad, pathological dismadurez) or signs (SDR, hepatomegalia, esplenomegalia, neurological signs, cardiomegalia, anasarca, petequias). When investigating the effect of the differences in the vectorial density (low, medium and high) of the zone of maternal residence, on the transmission of the infection of the mother infected to the fetus, we concluded that the rate of transmission of the congenital infection of T. cruzi is not modified by the level of endemicidad of the zone of maternal residence. By another infected new born sides whose mothers reside in zones of high endemicidad present/display, most frequently and of significant way, Apgar to 1 minute prematuridad or an association of these alterations with respiratory syndrome of distress or anasarca, when one compares them with new born of resident mothers in the zones of loss or medium endemicidad, mortality in this group is greater. These results suggest calls to account it of the mothers, in areas of high endemicidad, she is associate with a serious increase in the risk of Disease of newborn severe and mortal congenital Chagas in.

    Full Text Available Resumen La ciencia política en Bolivia inicia su organización y desarrollo formal con la recuperación de la democracia en 1982. Al grupo de cientistas políticos formados en Europa y México, se suma un pequeño grupo graduado en la Universidad Mayor de San Andrés que tendrá un papel significativo en el diseño de las reformas al sistema político desde 1993. A raíz de los grandes conflictos sociales, el país ha retrocedido institucionalmente y la disciplina debe volver su mirada a temas básicos, como el de la revalorización del sistema democrático. Asimismo, las organizaciones que aglutinan a los profesionales en ciencia política son muy nuevas, lo que les obliga primero a consolidarse como tales para desarrollar otro tipo de actividades.Abstract Political science in Bolivia initiated its organization and formal development with the recovery of democracy in 1982. Since 1993, in addition to those political scientists educated in Europe and Mexico, a small group of locally graduated political scientists from the Universidad Mayor de San Andrés has played a significant role designing the reforms to the political system. Nonetheless, as a result of deep social conflicts, the country has institutionally moved backwards and the discipline must return its focus to the basics, such as the revalorisation of the democratic system. Also, the organizations that agglutinate political scientists are very new; therfore, these are forced to first consolidate as institutions in order to develop other activities including a broader agenda in the discipline.

    Full Text Available Enterotoxigenic Escherichia coli (ETEC is recognized as the main cause of bacterial diarrhoea among children in Asia, Africa and Latin America but less investigated in Bolivia. OBJECTIVE: To determine the relation between enterotoxins, CFs and serotypes as well as the antimicrobial resistance patterns in a set of ETEC isolates collected from hospitalized children with acute diarrhea. In the present study we characterized 43 ETEC strains isolated from 2002 to 2006 from hospitalized children (0-5 years with acute diarrhea in Bolivia. The strains were analyzed for heat-labile (LT and heat-stable (ST enterotoxins and colonization factor (CF profiles, as well as for serogroups and antimicrobial resistance using phenotypic (ELISA, dot blot, slide agglutination and disc diffusion and genotypic (Multiplex PCR methods. Among the ETEC isolates tested, 30 were positive for LT, 3 for STh and 10 for LT/STh. Sixty-five percent (28/43 of the strains expressed one or more CF. The most common CFs were CS17 (n = 8 and CFA/I (n = 8. The phenotypical and genotypical results for toxins and CFs were congruent except for CS21 that was amplified in 10 of the strains by multiplex PCR, but CS21 pili was only detected phenotypically in four of these strains. The ETEC strains had diverse O and H antigens and the most common types were O8:H9 LT CS17 (n = 6; 14% and O78:HNM LT-ST CFA/I (n = 4; 9%. The analysis of antibiotic resistance showed that 67% (n = 29/43 of the strains were resistant to one or several of the antimicrobial agents tested. Presence of CFs was associated with antibiotic resistance. CONCLUSION: The most common toxin profile was LT 70%, LT/STh 23% and STh 7%. High antimicrobial resistance to ampicillin among serogroups O6, O8 and O78 were the most common.

    The investigated area involves the Pipeline Row of Bolivia Mato-Grosso, inserted in the South-center of The Serrana Province (Almeida, 1964). The south-center section of Serrana Province is a water divisor from those that leaks west directly to Paraguay River from the waters that leaks on the east side to Pantanal. This work has as main subject, to diagnose and to value the environmental impacts that occurred and can occur in the future on the brooks and springs where there were Pipeline Bolivia Mato-Grosso interference on its crossing at the Serrana area, in Caceres municipality. The springs monitor were done during 18 months (march, 2001 to September, 2001), during and after the ending of the works, including different climates and hydrologic conditions, making it possible to diagnose and to value the draining behavior on the drought and on the overflow epoch. So, we believe that the knowledge about the interferences, risks and alterations that reflects on the fluvial duct of the sub-basin that drains the Serrana Province and leaks to Paraguay River may be contributing indirectly or directly to the Pantanal conservation.

    In Bolivia's western highlands, at an altitude of some 3,600 metres, lie the largest identified reserves of lithium in the world. According to the latest estimates by the United States Geological Survey (USGS), beneath the 10,000 square kilometres of what are the world's most extensive salt flats, the Salar de Uyuni, there are some 6 to 9 million tonnes of lithium (Roskill 2008 nach Angerer, Marscheider-Weidemann, Wendl et al. 2009, Jaskula 2010a). Exploitation of those reserves has not yet begun, though the Bolivian government has constructed a small 6 million US Dollar pilot plant on the edge of the Salar de Uyuni, and has some ambitious plans: ''Lithium is the hope not just for Bolivia but for all inhabitants of the planet'', stated Bolivia's President Evo Morales in February 2009 (Bajak/Valdez 2009). Bolivia is one of the poorest countries in Latin America. The production of lithium, and the revenues it can generate, represents a major development opportunity for the country. Lithium is a key constituent of lithium ion batteries. Already in widespread use in mobile phones, camcorders and laptops, they are also increasingly needed to power hybrid and electric vehicles, which is why many analysts regard lithium as one of the key raw materials in the move towards sustainable mobility in the post-oil era (National Research Council (U.S.) 2008, Angerer et al. 2009, Tahil 2007; Chameides 2009). As the demand for lithium rises and its importance grows, the question arises as to the risks and opportunities associated with it. The resource booms of the past did little to promote Bolivia's development and improve the standard of living of its population. Indeed, Bolivia has a long history of resource-related conflict and political instability. This report (3.3) therefore investigates the risks and opportunities associated with the establishment of industrial-scale lithium production in Bolivia. Its analysis follows on from reports

    Middle Proterozoic rocks underlying the Andes in western Bolivia, western Argentina, and northern Chile and Early Proterozoic rocks of the Arequipa massif in southern Peru?? from the Arequipa-Antofalla craton. These rocks are discontinuously exposed beneath Mesozoic and Cenozoic rocks, but abundant crystalline clasts in Tertiary sedimentary rocks in the western altiplano allow indirect samples of the craton. Near Berenguela, western Bolivia, the Oligocene and Miocene Mauri Formation contains boulders of granodiorite augen gneiss (1171??20 Ma and 1158??12 Ma; U-Pb zircon), quartzose gneiss and granofels that are inferred to have arkosic protoliths (1100 Ma source region; U-Pb zircon), quartzofeldspathic and mafic orthogneisses that have amphibolite- and granulite-facies metamorphic mineral assemblages (???1080 Ma metamorphism; U-Pb zircon), and undeformed granitic rocks of Phanerozoic(?) age. The Middle Proterozoic crystalline rocks from Berenguela and elsewhere in western Bolivia and from the Middle Proterozoic Bele??n Schist in northern Chile generally have present-day low 206Pb/204Pb ( 15.57), and elevated 208Pb/204Pb (37.2 to 50.7) indicative of high time-averaged Th/U values. The Middle Proterozoic rocks in general have higher presentday 206Pb/204Pb values than those of the Early Proterozoic rocks of the Arequipa massif (206Pb/204Pb between 16.1 and 17.1) but lower than rocks of the southern Arequipa-Antofalla craton (206Pb/204Pb> 18.5), a difference inferred to reflect Grenvillian granulite metamorphism. The Pb isotopic compositions for the various Proterozoic rocks lie on common Pb isotopic growth curves, implying that Pb incorporated in rocks composing the Arequipa-Antofalla craton was extracted from a similar evolving Pb isotopic reservoir. Evidently, the craton has been a coherent terrane since the Middle Proterozoic. Moreover, the Pb isotopic compositions for the Arequipa-Antofalla craton overlap those of the Amazon craton, thereby supporting a link

    Full Text Available BACKGROUND: Chagas disease (American trypanosomiasis is a zoonotic or anthropozoonotic disease caused by the parasite Trypanosoma cruzi. Predominantly affecting populations in poor areas of Latin America, medical care for this neglected disease is often lacking. Médecins Sans Frontières/Doctors Without Borders (MSF has provided diagnostic and treatment services for Chagas disease since 1999. This report describes 10 years of field experience in four MSF programs in Honduras, Guatemala, and Bolivia, focusing on feasibility protocols, safety of drug therapy, and treatment effectiveness. METHODOLOGY: From 1999 to 2008, MSF provided free diagnosis, etiological treatment, and follow-up care for patients <18 years of age seropositive for T. cruzi in Yoro, Honduras (1999-2002; Olopa, Guatemala (2003-2006; Entre Ríos, Bolivia (2002-2006; and Sucre, Bolivia (2005-2008. Essential program components guaranteeing feasibility of implementation were information, education, and communication (IEC at the community and family level; vector control; health staff training; screening and diagnosis; treatment and compliance, including family-based strategies for early detection of adverse events; and logistics. Chagas disease diagnosis was confirmed by testing blood samples using two different diagnostic tests. T. cruzi-positive patients were treated with benznidazole as first-line treatment, with appropriate counseling, consent, and active participation from parents or guardians for daily administration of the drug, early detection of adverse events, and treatment withdrawal, when necessary. Weekly follow-up was conducted, with adverse events recorded to assess drug safety. Evaluations of serological conversion were carried out to measure treatment effectiveness. Vector control, entomological surveillance, and health education activities were carried out in all projects with close interaction with national and regional programs. RESULTS: Total numbers of

    Full Text Available The recent publication of an extensive report to king Philip II, sent to him in 1588 from what is now Bolivia, sheds new light on the evangelization of the native population of the Andes. Both the report and its author, a Spanish priest by the name of Bartolomé Álvarez, are news to scholars. Álvarez wrote more than fifty years after the arrival of the Spaniards in the territory and argued that Andeans had not been effectively converted to Christianity, despite token appearances to the contrary; they rejected Christian indoctrination and sought to free themselves from Spanish rule. For this failure of imperial policy, Álvarez blamed corrupted officials of the viceregal administration. He also blamed the jesuits and the Church authorities, whose ideas about the native population were naive. Only the lower secular clergy, the rural parish priests such as himself, are spared from his criticism, for which he provided a great deal of valuable Information, ethnographic as well as linguistic.La reciente publicación de un largo memorial dirigido a Felipe II en 1588 desde lo que hoy es Bolivia arroja nueva luz sobre el cambio que supuso en los Andes la difusión del cristianismo. Tanto la obra como su autor, un clérigo español llamado Bartolomé Álvarez, eran totalmente desconocidos hasta ahora. Su propósito, más de cincuenta años después de la llegada de los españoles, era demostrar que la población indígena no estaba aún realmente convertida, a pesar de las apariencias; rechazaba el cristianismo y aspiraba a verse libre de la presencia española. Álvarez hace responsable de este fracaso de la política imperial a las corruptelas del régimen virreinal, así como a la ingenua opinión que de los indígenas tenían los jesuitas y las autoridades eclesiásticas. Sólo el bajo clero secular, los doctrineros, como él mismo, se salvan de su censura, en la que incluyó abundante y valiosa información etnográfica y lingüística.

    An assemblage of 33 fossil pollen and spores, recovered from the 3600-m high Pislepampa locality of E. W. Berry, Eastern Cordillera, Bolivia, adds considerably to our knowledge of three aspects of the region in late Neogene time: (1) the paleovegetation, (2) the paleoclimate, and (3) the paleoelevation of the Central Andes. The plant microfossils recognized are Isoetes, Lycopodium (three types), Cnemidaria, Cyathea (three types), Grammitis, Hymenophyllum, Pteris, trilete fern spores (two types), Danaea, monolete fern spores (four types), Podocarpus, Gramineae, Palmae, Ilex, cf. Oreopanax, Cavanillesia, cf. Pereskia, Compositae (three types), Ericaceae, Tetrorchidium, and unknowns (three types). The diversity of the Compositae suggest that this flora has a maximum age around the Miocene-Pliocene boundary, that is, 6-7 million years. All members of the paleocommunity presently grow in the bosque montano húmedo (cloud forest) along the eastern slope of the Central Andes of Bolivia, which occurs between MATs (mean annual temperatures) of ∼10° and 20°C. The Pislepampa flora probably represents the lower limits of this forest because the fossil leaves collected by Berry from the same locality all have entire margins, suggesting that the flora grew near the cloud forest-tropical forest transition. Presently, the lower limit of the cloud forest forest has MATs of ∼20°C, a mean annual precipitation between 1000 and 1500 mm, and that part containing most of the identified genera of fossil pollen is found at elevations ∼1200-1400 m. These conditions are thus inferred for the Pislepampa flora; however, because of the uncertainty of the magnitude of global climate change and of possible changes in the ecological range of plant genera, we estimate an error of at least ±1000 m for the paleoelevation estimate. When the total uplift is corrected for probable amounts of erosionally driven isostatic rebound, the paleoelevation estimate suggests that from one-third to one

    Fernández Juárez, Gerardo

    2010-06-01

    Full Text Available The periodic exhumation and moving of dead bodies is a ritual of long history in the Central Andes, as revealed by “programs to extirpate idolatry” in the 16th and 17th centuries as well as ethnography on current All-Saints Day celebrations. Despite the open hostility of the Catholic Church toward “unorthodox” customs regarding the dead, remarkable instances of them can still be observed and studied at present, such as the socalled “Feast of the Ñatitas” which is held on every Sunday following All-Saints Day in the premises and church of “the General Cemetery” of La Paz. The current process of “ritual empowerment” of native peoples and social movements in Bolivia makes it all too clear the full significance of this feast as well as its commanding presence in ritual time and space against the policy of Catholic Church authorities in the country.

    La periódica exhumación y traslado de cadáveres constituye un comportamiento ritual de larga duración en los Andes Centrales, tal y como acreditan los “procesos de extirpación de idolatrías” de los siglos XVI y XVII, así como la etnografía contemporánea en relación con la festividad de Todos los Santos. A pesar de la actitud crítica y el celo de la Iglesia Católica contra este tipo de comportamientos ceremoniales “heterodoxos”, contamos con ejemplos especialmente elocuentes que continúan practicándose en la actualidad; es el caso de la llamada “Fiesta de las Ñatitas”, que corresponde al domingo siguiente a la del Primero de Noviembre y que se celebra en el camposanto y en el templo del Cementerio General de La Paz. El actual proceso de “empoderamiento ritual” de los pueblos originarios y los movimientos sociales en Bolivia hace resaltar el alcance significativo de esta fiesta y su éxito rotundo en tiempos de vivo conflicto con los responsables de la Iglesia Católica boliviana.

    Full Text Available Desde la Declaración de ministros de educación de países iberoamericanos en Santa Fe de Bogotá, 4-6 de noviembre de 1992, la descentralización educativa ha sido un tema recurrente de las reformas educativas en los países iberoamericanos, donde en algunos de ellos las experiencias de descentralización antecedieron a esta Declaración y en otros fueron posteriores. Las reformas educativas desarrolladas en los últimos años asociaron la descentralización educativa a la participación social y la mejora de la calidad educativa, entre otros temas. Este artículo aborda precisamente estos aspectos, interrogándose sobre qué tipo de descentralización estaría vigente en Bolivia, cuáles serían sus características en cuanto a la participación social y cómo estaría incidiendo en la calidad educativa. Se ha optado por un enfoque de análisis de las micropolíticas y de las prácticas sociales de los actores, apoyándose metodológicamente en dos estudios de caso: La Paz y Tarabuco (Bolivia. El artículo sugiere que tanto las políticas de descentralización educativa como los enfoques teóricos de análisis desde las ciencias sociales han avanzado poco en explicar el fenómeno de las relaciones sociales de poder a nivel local que afecta a la naturaleza de cualquier proceso de descentralización, porque en los poderes centrales del Estado persiste una hegemonía del enfoque gerencialista y una visión esencialmente burocrática de la educación.

    This paper summarized the results of comprehensive petro-mineralogical and geochemical (archeometrical) investigation of Inka Period ceramics excavated from Inka (A.D. 1438-1535) and Late Intermediate Period (A.D. 1000/1200-1438) sites of the Paria Basin (Dept. Oruro, Bolivia). Applying geological analytical techniques we observed a complex and important archaeological subject of the region and the era, the cultural-economic influence of the conquering Inkas in the provincial region of Paria appearing in the ceramic material. According to our results, continuity and changes of raw material utilization and pottery manufacturing techniques from the Late Intermediate to the Inka Period are characterized by analytical methods. The geological field survey provided efficient basis for the identification of utilized raw material sources. On the one hand, ceramic supply of both eras proved to be based almost entirely on local and near raw material sources. So, imperial handicraft applied local materials but with sophisticated imperial techniques in Paria. On the other hand, Inka Imperial and local-style vessels also show clear differences in their material which suggests that sources and techniques functioned already in the Late Intermediate Period subsisted even after the Inka conquest of the Paria Basin. Based on our geological investigations, pottery supply system of the Paria region proved to be rather complex during the Inka Period.

    Under tropical conditions, water discharge from glaciers is crucial for water resources in the dry season, as it is the case for La Paz, Bolivia (16°S). In the current study, the glacier water supply of La Paz city has been assessed at annual and seasonal time-scale for the first time thanks to the mass balance analysis of 70 glaciers located within the drainage basins of La Paz between 1963 and 2006. The ice melting has contributed to about 15% of the water resources of the city at an annual scale, 14% in the humid season and 27% in the dry season. Despite the loss of about the half of the glaciers areas during this period, the runoff at La Paz did not change significantly. It reveals that ice melting rise compensated the surface areas decrease. Contrary, assuming that glaciers disappear in the future and precipitation does not change in the catchment areas, the runoff should diminish by about 12% at annual scale, 9% during the humid season and 24% during the dry season.

    Genetic variability of Trichomycterus from the region of Torotoro (Bolivia, Upper Amazon), distributed in the same watershed where the habitat is structured by waterfalls, canyons and a cave, was studied by allozyme (twelve putative loci) and RFLP-mtDNA (DLoop and cytochrome b) analyses. Alloenzymatic variation studied by Correspondence Analysis and Maximum Likelihood Analysis revealed a four-group structure, which was largely congruent with the distribution of the 14 mtDNA haplotypes. Two of these four clusters (I and II) were differentiated by two diagnostic loci (IDH and G3PDH), two semi-diagnostic loci (PGM and 6PGDH) and consequently a very high F(st )value (estimator theta = 0.77). Therefore, clusters I and II are reproductively isolated. The distribution limit of these two (sibling) species does not correspond to those of the morphological species of Trichomycterus identified in this region: the epigean T. cf. barbouri and the hypogean T. chaberti. However, hypogean fish exhibited two mtDNA haplotypes, a private one and another shared with the epigean Trichomycterus from upstream reaches.

    Full Text Available At their most local, initiatives to reduce emissions from deforestation and degradation (REDD will depend on rural people to manage forest resources. Although the design of frameworks, mechanisms and arrangements, to implement REDD programs have received significant attention, it is not yet clear how REDD+ will function on the ground or how the participation of local populations will be assured. Community forest management (CFM could be an option under REDD+ depending on how it is negotiated, largely because of the expectation that CFM could reduce emissions from deforestation and degradation. Examining institutional factors in the emergence of successful CFM systems and local forest enterprises could provide valuable lessons for REDD planners. We examine cases of CFM development in Mexico, Brazil and Bolivia, to assess the role of multi-scaled governance institutions in their development. Comparing and contrasting advanced CFM systems to regions where it is still emerging, we will show how the establishment of a local organizational base for communal resource management is crucial.

  17. Market-Based Instruments for the Conservation of Underutilized Crops: In-Store Experimental Auction of Native Chili Products in Bolivia

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Native chilies (Capsicum spp. are currently underutilized in Bolivia, one of this crop’s centers of diversity. Fewer local farmers cultivate native chilies annually due to low market demand. Increasing its private use value can lead to the in-situ conservation of this crop. The objective of the paper is to evaluate the market acceptability of three native chili products: (a chili marmalade; (b chili cooking paste; and (c pickled chilies. Multi-product Becker-DeGroot-Marschak experimental auctions and hedonic tests were conducted with 337 participants in La Paz and Santa Cruz. Data were analyzed using seemingly unrelated regressions. Results suggest that consumers are willing to pay price premiums of about 25–50 percent. Biodiversity conservation and improvements in farmers’ quality of life statements would not have influence on first purchase decisions but rather on repurchase decisions and therefore on consumers’ product loyalty. This in turn could lead to sustainable agro-biodiversity conservation, centered on consumers’ purchase of these products over time.

    We assessed the prevalence of intestinal parasites among 268 2-12-year-old children living in rural areas, small villages, and semi-urban areas of the Chaco region, south-eastern Bolivia. The overall parasitism was 69%. Only protozoa, helminths, or co-infections were observed in 89.2%, 5.9%, or 4.9% of the positive children, respectively. A significant progressive increase in overall parasite prevalence was found when passing from rural areas to small villages and semi-urban areas. The most commonly found species were Entamoeba coli (38.4%), Giardia intestinalis (37.7%), and Blastocystis spp. (16%). Hymenolepis nana was the most prevalent helminth (5.6%), followed by Ascaris lumbricoides and hookworms (1.5% and 0.4%) evidenced only in rural areas and in villages. Molecular diagnostics identified Blastocystis subtypes 9 and 2, and 5 infections by Entamoeba histolytica and 4 by Entamoeba dispar. The dramatic decrease in prevalence of soil-transmitted helminths with respect to that observed about 20 years ago (> 40%) evidences the success of the preventive chemotherapy intervention implemented in 1986. Health education and improved sanitation should be intensified to control protozoan infections.

    Cutaneous and mucosal leishmaniasis, caused in South America by Leishmania braziliensis, is difficult to cure by chemotherapy (primarily pentavalent antimonials [Sb(V)]). Treatment failure does not correlate well with resistance in vitro, and the factors responsible for treatment failure in patients are not well understood. Many isolates of L. braziliensis (>25%) contain a double-stranded RNA virus named Leishmaniavirus 1 (LRV1), which has also been reported in Leishmania guyanensis, for which an association with increased pathology, metastasis, and parasite replication was found in murine models. Here we probed the relationship of LRV1 to drug treatment success and disease in 97 L. braziliensis-infected patients from Peru and Bolivia. In vitro cultures were established, parasites were typed as L. braziliensis, and the presence of LRV1 was determined by reverse transcription-polymerase chain reaction, followed by sequence analysis. LRV1 was associated significantly with an increased risk of treatment failure (odds ratio, 3.99; P = .04). There was no significant association with intrinsic Sb(V) resistance among parasites, suggesting that treatment failure arises from LRV1-mediated effects on host metabolism and/or parasite survival. The association of LRV1 with clinical drug treatment failure could serve to guide more-effective treatment of tegumentary disease caused by L. braziliensis.

    Implications of a new collection of lycophytes of the genera Haplostigma Seward and Paleostigma Kräusel and Dolianiti from southern Bolivia and northern Argentina are presented. Fragmented herbaceous stems of lycophytes preserved as compressions, impressions and casts come from the Middle and Late Devonian Pescado (Huamampampa), Los Monos and Iquiri formations at Mataral, Yesera, Angosto del Pescado and Balapuca. The interbedded shales and siltstones bearing the lycophytes were also examined for palynology. They yielded mostly terrestrial palynomorphs with Grandispora pseudoreticulata and other Eifelian to Givetian species and fewer microplanktonic species (i.e., acritarchs, prasinophytes, chitinozoans). At Yesera, diagnostic spores and elements of the microplankton suggest a Givetian-Frasnian up to early Famennian age for the Haplostigma beds. Moreover, presence of the same brachiopod taxon in the Haplostigma intervals at Yesera Dique (palynologically barren) and Yesera Centro supports their correlation. This new information supports terrestrial connections between these Bolivian and Argentine areas and other regions of South America in the Eifelian - Givetian Afrosouthamerican Subrealm, which extended up to the early Famennian.

    Full Text Available Biocultural heritage-based products, including regional specialty foods, are increasingly part of sustainable rural development strategies. While export-oriented biocultural products are often the most visible, we examine the role of campesino gastronomic heritage in the Central Valley of Tarija, Bolivia, as a case study of a local market-centered biocultural resource-based development strategy reflected in an alternative agri-food network. We develop a biocultural sustainability framework to examine this network from ecological, economic and sociocultural perspectives. Data are drawn from interviews (n = 77, surveys (n = 89 and participant observation, with primary and secondary producers of traditional and new products, as well as restaurant owners, market vendors and local consumers. We find that campesino biocultural heritage and the alternative agri-food network surrounding it represent an influential territorial project that underpins many household economies, particularly for women. We conclude that the relatively small investments by local governments to promote campesino gastronomic heritage are having positive ripple effects on small-scale producer livelihoods and on biocultural sustainability. We suggest that further support to increase market access and reduce other barriers to participation in alternative food networks will likely increase the options and benefits available to small-scale producers mobilising campesino gastronomic heritage within the local economy.

    Plehniella Szidat, 1951 is emended based on new collections from South American long-whiskered catfishes. It is clearly differentiated from Sanguinicola Plehn, 1905 by lacking lateral tegumental body spines and by having 6 asymmetrical caeca. Plehniella sabajperezi sp. n. infects body cavity of Pimelodus albofasciatus (Mees) from the Demerara and Rupununi Rivers (Guyana) and Pimelodus blochii (Valenciennes) from Lake Tumi Chucua (Bolivia) and Napo River (Peru). It differs from Plehniella coelomicola Szidat, 1951 (type species) by having a thin-walled vas deferens that greatly exceeds the length of cirrus-sac and that joins the cirrus-sac at level of ovovitelline duct and ootype, an internal seminal vesicle that is absent or diminutive, and a cirrus-sac that is spheroid, nearly marginal, and envelops the laterally-directed distal portion of the male genitalia. Plehniella armbrusteri sp. n. infects body cavity of P. blochii from Lake Tumi Chucua (Bolivia). It differs from P. coelomicola and P. sabajperezi by having a relatively ovoid body, a massive intestine comprising caeca that are deeply-lobed to diverticulate and terminate in the posterior half of the body, a testis that flanks the distal tips of the posteriorly-directed caeca, and a proximal portion of the vas deferens that loops ventral to the testis. Small adults (Plehniella sp.) collected from body cavity of Pimelodus grosskopfii (Steindachner) from Cienega de Jobo and Canal del Dique (Colombia) differ from congeners by having a posteriorly-constricted body region, an anterior sucker with concentric rows of minute spines, an elongate anterior oesophageal swelling, short and wide caeca, and a male genital pore that opens proportionally more anteriad. This study nearly doubles the number of aporocotylids documented from South America Rivers and comprises the first record of a fish blood fluke from P. blochii, P. albofasciatus and P. grosskopfii as well as from Bolivia, Colombia, Guyana or Peru.

    Logging activity in the trinational southwestern Amazonia will grow in importance as a driver of regional land-use change as expanding road access facilitates both timber extraction and transport to international markets. Official data on current activity in this ~50 million ha region are limited and inconsistent with differences as much as twenty-fold between official estimates; nevertheless, they serve as guides for understanding the relative magnitude of logging activities. For 2000, an estimated 5 million m3 of timber were commercialized in Rondonia, 400,000 m3 in Acre, Brazil, and 200,000 m3 for the combined departments of Pando, Bolivia and Madre de Dios, Peru. About 70% of this timber originates from clear cutting done for pasture and agriculture activities, nearly a third from unregulated selective logging, and only 2% from managed selective logging. Eight timber species are preferentially extracted. The total area for timber concessions in Acre, Pando and Madre de Dios extends to about 4 million ha for a potential timber supply of 65 million m3. About 150,000 m3/yr of illegal timber is confiscated by federal and state agencies in Acre, Pando and Madre de Dios. Problems of enforcement in the region are due principally to the lack of trained personnel and little cooperation among agencies of the three countries. Proposed development plans indicate a 3- to >10-fold increase in logging activity in the Acre and Pando regions during the coming decade. More detailed studies are urgently needed to guide sustainable development of this resource in southwestern Amazonia.

    Denudation processes and sediment transfer are investigated in a high-elevation, low-relief environment (eastern Altiplano, Bolivia) using 10Be, 26Al, and in situ 14C analysis in fluvial sediments. Concentrations of the long-lived nuclides 10Be and 26Al yield consistently low catchment-wide denudation rates of ~ 3-29 mm ky- 1 (integrating over 21-194 ky), which reflect the low geomorphic gradients and the discontinuity of fluvial transport along the eastern Altiplano margin. No significant correlation is recorded between denudation rates of individual catchments and morphological basin parameters (slope, area, elevation). This is attributed to the overall little variability in morphology. The agreement between the denudation rates and published modern sediment discharge data suggests steady landscape evolution of the eastern Altiplano from the latest Pleistocene until today. While 10Be and 26Al provide long-term estimates on sediment production, in situ cosmogenic 14C is used to trace short-term sediment storage. In situ 14C concentrations are comparatively low indicating that 14C decayed during alluvial storage over at least the past ~ 11-20 ky. We assume storage at shallow depth (2 m) and consider the influence of soil-mantled hillslopes on the in situ 14C concentration. Our results illustrate the importance of sediment storage even over short distances and demonstrate the potential of in situ 14C to study sediment routing and transfer times within drainage systems. However, this study also demonstrates that the long-lived 10Be and 26Al nuclides can provide adequate estimates on long-term denudation rates even if sediment transport is not fast but interrupted by several thousands of years of storage.

    Evaluation of foreland basin deposystems and provenance across southern Bolivia reveals punctuated growth of the central Andean orogenic wedge. New and published sedimentology, provenance data, stratigraphy, subcrop mapping, and apatite (U-Th)/He thermochronometry along two transects (19.5, 21°S) from the easternmost Eastern Cordillera (EC) to the western Subandean Zone (SAZ) shed light on Late Cretaceous-Miocene thrust belt and foreland basin dynamics. Sediment dispersal patterns are constrained by paleocurrents, detrital zircon U-Pb geochronology, sandstone petrography, and conglomerate clast compositions. Spatial and temporal changes in the Andean thrust belt are recorded in asymmetric foreland basin thicknesses, facies distributions, and provenance within the EC (Incapampa and Camargo synclines) and SAZ (El Rosal and Entre Rios synclines). The >4 km uppermost Cretaceous-lower Miocene EC succession and ~2.5 km upper Oligocene-Miocene SAZ clastic successions record a shift from fluvial backbulge to pedogenic forebulge deposition. Braided, meandering, and lacustrine foredeep deposition records the most-rapid subsidence, with a later shift to progradational braided and alluvial fan deposition in the wedge-top zone. Growth strata preserved in EC and SAZ wedge-top deposits suggest unsteady eastward advance of the deformation front. Distal foreland deposits show west-directed paleocurrents with >1 Ga detrital zircon populations. Emerging Andean sources are indicated by east-directed paleocurrents, 36-25 Ma), Interandean Zone (IAZ, ~22-7 Ma) and SAZ (<6 Ma) can be linked to eastward passage of a flexural forebulge, recorded as a 50-200 m thick condensed zone in EC and SAZ basin fill. Integrated assessment of basin architecture, provenance, and exhumation highlights the potential influence of pre-Cenozoic IAZ heterogeneities on orogenic wedge growth.

    Full Text Available El propósito general de este trabajo es contribuir a la comprensión de las transformaciones políticas de las comunidades indígenas de la región andina de Bolivia a partir de las reformas estatales implementadas en la década de 1990, desde una perspectiva que atiende a la manera cómo la comunidad indígena, en nuestro caso el ayllu Kirkyawi, se ha reconfigurado política y organizativamente a partir del nuevo marco legal, institucional y político. En el mismo pretendemos mostrar que es la “comunidad” construida desde su sistema de organización política propia la que podría constituirse jurídicamente como “nación” en el contexto del Estado Plurinacional, es decir, que es necesario pasar del “reconocimiento” de la diversidad étnica y cultural a la construcción de un sistema político administrativo que contemple la posibilidad de que las comunidades indígenas puedan construir su verdadera autonomía; es decir, determinar el sistema político por el que les conviene regirse, el sistema de autoridades, las instancias de participación y toma de decisiones y las instancias y formas legislativas propias. En definitiva, la posibilidad de gobernarse a sí mismos. Este es el proyecto político que surge a partir de la comunidad para la constitución de las nacionesdel Estado Plurinacional.

    El tema de la autonomía en Bolivia tiene varias aristas, mientras para unos es la lucha por la autodeterminación de los pueblos originarios, para otros es la búsqueda de una mayor descentralización política y económica. Es un tema arraigado históricamente entre profundas negaciones y lucha por el poder. Los medios de comunicación son actores clave en éste proceso, los posicionamientos discursivos particularmente en las editoriales expresan de que lado están, por tanto, estudiar estas represen...

    Full Text Available El objetivo fue identificar el conocimiento y control del vector (Triatoma infestans transmisor de la enfermedad de Chagas en comunidades guaraníes de Bolivia, conocido como vinchuca. Se trata de un estudio descriptivo de una serie de 98 casos mediante cuestionario semiestructurado sobre: conocimiento de la vinchuca, si produce alguna enfermedad, nombre de la enfermedad y sus consecuencias, así como las conductas de higiene: patio, vivienda, corrales. La vinchuca fue suficientemente conocida (98%, aunque sólo el 14,3% identificó el nombre de la enfermedad. Pese a ser ambientes apropiados para la proliferación de vinchucas, se limpian con poca frecuencia: el 28,6% limpia la vivienda, el 42,9% el patio y el 7,1% el corral. Se evidencia una división sexual del trabajo: mientras las mujeres limpian la vivienda y el patio, los varones limpian los corrales. La experiencia enseña el valor del proyecto de construcción de viviendas saludables y educación para la salud en la medida en que la comunidad los valora. Probablemente, las mujeres son el mejor grupo destinatario, pues realizan más tareas preventivas y no se ausentan con tanta frecuencia de la comunidad.The aim of this study was to identify knowledge and control of vectorial transmission (Triatoma infestans, known as vinchuca of Chagas' disease in Guaraní Communities in Bolivia. We performed a descriptive study of a series of 98 individuals through a semi-structured questionnaire. Interviewees were asked about their familiarity with vinchuca, whether they thought vinchuca produced disease, the name of the disease and its consequences, as well as behavior related to eliminating the domestic insect vectors, such as cleaning of the home, backyard and corral. The insect vector was sufficiently well known (98%, although the name of the disease was identified by only 14.3% of the interviewees. Although the dwellings favored insect proliferation, they were not frequently cleaned: 28.6% cleaned

    TBG - Transportadora Gasoduto Bolivia-Brasil S.A, executes routine maintenance works at the Gas Pipeline Right of Way, seeking its integrity. In the wetlands of Pantanal, near the Paraguay river crossing, the organic-alluvial soil was submitted to the process of subsidence. This process, associated with the river water flow erosion, shrank the soil volume and diminished or extinguished the pipeline land cover. The pipeline was exposed to the environment, and submitted to tension stresses and the risk of low cycle fatigue during the floods. The cathodic protection system also had to be evaluated, specially in the drought. To mitigate the problem, the embankment technique was adopted using sandy soil, reinforced with polyester geo-webs and with woven polipropene geo-textiles. The solution also used geo-webs with soil-cement as protection elements against the degradation of the geo-textiles blankets. Some monitoring works are associated with those interventions: monitoring of cathodic protection; topographical verification of horizontal and vertical displacements of the pipeline; levels of land covering, and rainfalls and flood measurement. The base of the embankment was built with hydraulic transported soil, and at the end consistently supported the gas pipeline. (author)

    A hundred and seventy kilometers from Campo Grande city, on Mato Grosso do Sul State, the Brasil-Bolivia Gas Pipeline crosses a 8,5 meters high landfill, over a drainage systems made of a 2,8 meters of diameter corrugated pipe. This drainage pipe was installed to allow the drainage of the valley, and the landfill above it was built so the Gas pipeline could cross easier the 80 meters deep and 30 degree vertices valley. This paper illustrates the work tasks and solutions taken to monitor and guarantee the integrity of the drainage and landfill structures, as well as the integrity of the Gas Pipeline. Some of the work tasks illustrated are the investigation of the support conditions of the Gas Pipeline, the analysis of a drainage system under the pipeline, on a rocky soil, the analysis of the stability of the landfill, the construction of a gravity retaining walls and the monitoring of the deformations on the drainage pipe.
