Item Open Access An Economic Analysis of REDD Carbon Payments on Agricultural Expansion in Bolivia(2009-04-22T18:48:05Z) Stich, MonicaAs deforestation accounts for a significant percentage of worldwide carbon emissions, reducing emissions from deforestation and degradation (REDD) has been the focus of intense international debate. REDD programs offer a financial mechanism to compensate areas that would have been deforested for avoided carbon emissions above an established baseline. This study examined the feasibility of such a program in El Chore Forest Reserve in Bolivia, which faces destruction from the illegal seizure of land by poor immigrant farmers. Three main components were used to obtain a spatial distribution of the minimum price of carbon required for conservation (i.e. compensate for the opportunity cost of agriculture): estimation of biomass, prediction of deforestation, and calculation of the opportunity cost. A map of biomass was estimated by regressing spectral enhancements of 2007 satellite imagery on a spatially coarse reference map of the Amazon region. It was concluded that the reserve has an average biomass of 121.1 Mg biomass/ha with a standard deviation of 15.58. The spatial probability of future deforestation was calculated using a logistic analysis on deforestation between 2001 and 2004 based on biophysical variables. By applying a projection of area deforested per year based on historical trends, the results indicated the area that would be deforested. In the absence of intervention, it was predicted that 44% of the forest reserve would be converted to agriculture by 2036 (Kappa: 0.57). The opportunity cost was modeled using profit predictions of the four main crops (rice, soybean, maize, wheat). Depending on the crop, projections indicated that prices would increase 35-100% and yields were expected to increase 55-88% by 2040. Expected profits were scaled based on the suitability of the land by crop. The average opportunity cost for a three-year time period ranged from $904/ha in 2006 to $2143/ha in 2036. Using an economic model with an 8% discount rate the average price would need to be $21.17/tC. Since the biomass estimate is conservative, this is likely an upper bound on the price of carbon. These results could be used to inform the development of a carbon program and determine target areas for conservation initiatives.Item Open Access Conscript Nation: Negotiating Authority and Belonging in the Bolivian Barracks, 1900-1950(2012) Shesko, ElizabethThis dissertation examines the trajectory of military conscription in Bolivia from Liberals’ imposition of this obligation after coming to power in 1899 to the eve of revolution in 1952. Conscription is an ideal fulcrum for understanding the changing balance between state and society because it was central to their relationship during this period. The lens of military service thus alters our understandings of methods of rule, practices of authority, and ideas about citizenship in and belonging to the Bolivian nation. In eliminating the possibility of purchasing replacements and exemptions for tribute-paying Indians, Liberals brought into the barracks both literate men who were formal citizens and the non-citizens who made up the vast majority of the population. This study thus grapples with the complexities generated by an institution that bridged the overarching and linked divides of profession, language, literacy, indigeneity, and urbanity.
Venturing inside the barracks, this dissertation shows how experiences of labor, military routines, punishment, teasing, and drinking led to a situation in which many conscripts became increasingly invested in military service, negotiated its terms, and built ties that transcended local power structures. In addition to examining desertion, insubordination, and mutinies, it provides an explanation of the new legal categories created by military service, such as reservist, omiso, remiso, and deserter. It then points to the 1932-1935 Chaco War and its aftermath as the period when conscription became a major force in tying an unequal nation together. The mass mobilization necessitated by the war redefined the meaning and terms of conscription, even as the state resorted to forcible mass impressment throughout the national territory while simultaneously negotiating with various interest groups. A postwar process of reckoning initiated by the state, combined with mobilization from below by those who served, added a new hierarchy of military service that overlaid and sometimes even trumped long-standing hierarchies based on education, language, profession, and heritage.
This study thus explores conscription as a terrain on which Bolivians from across divides converged and negotiated their relationships with each other and with the state. The unique strength of this work lies in its use of unpublished internal military documents, especially court-martial records. These sources are further enriched by extensive use of congressional debates, official correspondence, reports of foreign military attachés, memoirs, and published oral histories. Through an analysis of these sources, this dissertation reveals not only elites’ visions of using the barracks to assimilate a diverse population but also the ways that soldiers and their families came to appropriate military service and invest it with new meanings on a personal, familial, communal, and national level. In the process, a conscript nation would eventually emerge that, while still hierarchical and divided by profound differences, was not merely a project of an assimilationist state but rather constructed in a dialectical process from both above and below.
Item Open Access Estimating the Opportunity Cost of Lithium Extraction in the Salar de Uyuni, Bolivia(2009-12-04T05:15:30Z) Aguilar-Fernandez, RodrigoIf the world plans to be moving away from oil based transport and towards hybrid and electric vehicles, lithium supply is the key factor. The Salar de Uyuni in Bolivia holds the largest source of lithium in the world; however, its extraction will bring a trade off with the environment. Due to the arid nature of the climate, the Salar de Uyuni basin has a sensitive ecosystem heavily dependent on water resources. Consequently, local people’s subsistence and well-being also depend on water resources on a daily basis. Studies conducted in the Salar de Uyuni basin concluded that using the same spring as a production input, water consumption for lithium extraction and crop irrigation cannot simultaneously take place. Thus, the fresh water use from the San Geronimo River creates two mutually exclusive projects, lithium mining and quinoa crop with irrigation, generating different gains to the economy of the region. The incremental cash flows model used in this study provides an estimate of the benefits that each project would provide. The results indicate that even after subtracting the opportunity cost of not conducting the quinoa irrigation project and reducing the uncertainty of the model parameters, the net present value (NPV) of the lithium extraction project is still positive and large relative to the economy of the study area. Nevertheless, the distributional and social differences have to be carefully assessed in the future according to the ecosystem services and the financial model described in this study. In order to incorporate market distortions and foreign exchange implications on the financial model, further economic research is required on both projects. Finally, water resources and its competing uses should be recognized as an economic good, so it could be managed more efficiently and used more equitably in this ecosystem.Item Open Access Hydrologic variation and lake sediments: a reconstruction of the Bolivian Lowlands over the last 5,500 years(2011-04-29) Carnes, AllysonSediment cores raised from the shallow floor of Lake Opabusu in the Bolivian Gran Chaco record 5500 years of hydrologic change in the surrounding region. Sediment samples were analyzed for their organic carbon and nitrogen contents and stable isotopic ratios as well as for their CaCO3 contents. These analyses indicate a general trend from drier to wetter conditions from the mid-Holocene to present. This trend is consistent with changes observed in the northern Bolivian lowlands and in the adjacent tropical Andes. Accompanying the increase in precipitation, the C/N ratio and 13C content of sedimentary organic matter indicate an apparent trend from algal to terrestrial sources as well as a possible increase in C3 plants at the expense of drought-tolerant C4 plants. Other studies done in the neighboring Altiplano and Amazon regions corroborate the movement toward wetter conditions, and work done in the Bolivian Amazon supports the idea of a shift of the type and amount of vegetative cover in Lake Opabusu's watershed. This trend toward wetter conditions is likely governed by an orbitally-forced increase in summer insolation. The higher insolation at present intensifies the South American monsoon resulting in greater precipitation and higher lake levels; drier mid-Holocene conditions coincided with lower summer insolation. Several, but not all, general circulation model simulations, suggest that the future climate of the study region will be significantly drier and warmer by the end of the 21st century. Both changes would contribute to a negative water balance and it is likely that Lake Opabusu will dry completely in the near future. Although the lake has shrunk and expanded during the last century (as seen in historic air photos), there is no evidence within the sediment core, that the lake has previously desiccated to the depth of the core site at any time in the past five millennia.Item Open Access Leapfrogging to a Green Building Code in Bolivia: A Policy Analysis(2016-04-27) Legge, Darren; Stanton, Darius II; Tran, TheoIn Bolivia, building codes are a nascent development. This presents an opportunity to learn from the international community, possibly even “leapfrogging” directly to a code that incorporates environmentally sustainable features. On behalf of our client, Partners of the Americas, this report assesses the opportunity for Bolivian municipalities to adopt commercial building codes similar to those developed by the International Code Council. Specifically, we analyze the International Building Code (IBC) and the International Green Construction Code (IgCC) for use in Bolivia’s three principal cities: La Paz, Cochabamba and Santa Cruz. We analyze the policies’ effectiveness in achieving building safety and environmental health improvements, as well as their potential economic costs and benefits. We also evaluate the feasibility of policy adoption and implementation.Item Open Access Measuring the effects of compensation for environmental services interventions on social norms and conservation behavior in Bolivia(2010-04-28T19:44:55Z) Turiansky, AbbiePayments for Environmental Services (PES) that give landowners a financial incentive to manage their land to provide valuable environmental services may provide an efficient way to conserve forest land and improve the livelihoods of landowners receiving payments. While these programs appear promising, little rigorous evaluation has been conducted to learn about the impacts of PES on the environment or on the people and communities involved. Fundación Natura Bolivia, a conservation NGO, plans to implement a PES program in a new management area, accompanied by a study that aims to identify and understand the impacts of PES. Identifying the impacts of PES and determining why they occur requires baseline information from a program site so that changes can be monitored as the program is implemented. The objective of this research is to identify key environmental, social, economic, and institutional indicators to include in the study and to design a survey instrument to measure these indicators. This report is intended as a guide for Fundación Natura Bolivia as they conduct this and future evaluations of their programs. Key indicators were identified through a literature survey and extensive fieldwork conducted in Bolivia in the summer of 2009. Environmental indicators include agricultural land use, forest use, decision-making, and environmental awareness. Socioeconomic indicators include household consumption, economic access, employment and income sources, and non-income measures of wellbeing. Finally, institutional indicators include community organizations and informal institutions, environmental norms and attitudes, and relationships with outside organizations and other communities. A survey designed to measure these indicators is included with this report, along with recommendations for survey design and implementation.Item Open Access Oil and gas projects in the Western Amazon: threats to wilderness, biodiversity, and indigenous peoples.(PLoS One, 2008-08-13) Finer, Matt; Jenkins, Clinton N; Pimm, Stuart L; Keane, Brian; Ross, CarlBACKGROUND: The western Amazon is the most biologically rich part of the Amazon basin and is home to a great diversity of indigenous ethnic groups, including some of the world's last uncontacted peoples living in voluntary isolation. Unlike the eastern Brazilian Amazon, it is still a largely intact ecosystem. Underlying this landscape are large reserves of oil and gas, many yet untapped. The growing global demand is leading to unprecedented exploration and development in the region. METHODOLOGY/PRINCIPAL FINDINGS: We synthesized information from government sources to quantify the status of oil development in the western Amazon. National governments delimit specific geographic areas or "blocks" that are zoned for hydrocarbon activities, which they may lease to state and multinational energy companies for exploration and production. About 180 oil and gas blocks now cover approximately 688,000 km(2) of the western Amazon. These blocks overlap the most species-rich part of the Amazon. We also found that many of the blocks overlap indigenous territories, both titled lands and areas utilized by peoples in voluntary isolation. In Ecuador and Peru, oil and gas blocks now cover more than two-thirds of the Amazon. In Bolivia and western Brazil, major exploration activities are set to increase rapidly. CONCLUSIONS/SIGNIFICANCE: Without improved policies, the increasing scope and magnitude of planned extraction means that environmental and social impacts are likely to intensify. We review the most pressing oil- and gas-related conservation policy issues confronting the region. These include the need for regional Strategic Environmental Impact Assessments and the adoption of roadless extraction techniques. We also consider the conflicts where the blocks overlap indigenous peoples' territories.Item Open Access POLICY IMPLICATIONS OF NATIONALIZATION OF OIL AND NATURAL GAS INDUSTRY IN LATIN AMERICA(2007-05) Cabezas, Brian F.Nationalization is a particular type of organizational structure where the state or nation controls the industry as opposed to private companies or multinational organizations. If one imagines a continuum of organizational structure, nationalization and privatization would be at opposite ends. Nationalization could include joint ventures where the state controls the industry but allows for private companies to participate in the resource extraction and retain some of the profit. Within the past few years, Venezuela and Bolivia have announced plans to renationalize their oil and natural gas industry. The first part of this project seeks to perform a qualitative analysis to discern the common characteristics of a nationalized country focusing specifically on four countries – Bolivia, Venezuela, Mexico and Nigeria. There are various components influencing the efficiency of a nationalized industry including civil society, regionalism, and reliance on oil. The main findings were that a nationalized country with a high reliance on oil or natural gas and weak financial institutions will have an authoritarian form of government, and that there will likely be more incidences of Latin American countries nationalizing in the near future if oil prices remain high. The project also performs a quantitative analysis on indirect measures of efficiency using subsidies and also analyzes the effect of nationalization on social development using the Gini coefficient (a measure of income equality) and public spending on education. Nationalization is found to have a positive effect on income equality and a negative effect on public spending on education. The project culminates with policy recommendations specifically focused on the four selected countries with implications for broader applications. The main objectives of the recommendations are to strengthen financial institutions, diversify the economy, and increase transparency and accountability of the industry.Item Open Access Potential health risks of trace elements in adobe brick houses in a historical mining town: Potosí, Bolivia(2015-04-21) McEwen, AbigailThe objectives of this study were to investigate trace elements in adobe houses and to characterize potential health risks from children’s exposure in Potosí, Bolivia. The city of Potosí sits at the base of the Cerro Rico Mountain, which has been mined heavily for its rich polymetallic deposits since the Spanish Colonial era in the 16th century, leaving a legacy of pollution that is not well understood. In this study, total trace elements were quantified in dirt floor, adobe brick, and surface dust samples from 49 houses. Mean concentrations of total mercury, lead, and arsenic in adobe bricks were significantly greater than concentrations in Sucre, Bolivia, a non-mining town used as a reference site, and exceeded US-based soil screening levels that are protective of human health. Adobe brick samples were further analyzed by simulated gastric fluid (GF) extraction, which approximates bioaccessibility. Mean GF extractable concentrations of mercury, arsenic, and lead were 0.841, 14.9, and 30.0 percent of the total concentration, respectively. Total and GF extractable concentrations of these elements were used to estimate exposure and potential health risks to one and six year old children following incidental ingestion of element enriched adobe brick particles. Although the majority of households have concentrations of total mercury and arsenic that represent a potential health risk, the percentage significantly decreases when GF extractable concentrations are considered. However, even when GF extractable lead is considered, the majority of the households have lead concentrations in adobe bricks that represent a potential health risk to children. This is the first study to quantify trace elements in adobe houses and the results show that the building materials in these houses are a source of exposure to potentially toxic trace elements in South American mining communities. Additional environmental sampling, biomonitoring, and exposure questionnaires are needed to fully characterize sources of exposure and to understand potential adverse health outcomes within the community.Item Open Access Residential metal contamination and potential health risks of exposure in adobe brick houses in Potosí, Bolivia.(The Science of the total environment, 2016-08) McEwen, Abigail R; Hsu-Kim, Heileen; Robins, Nicholas A; Hagan, Nicole A; Halabi, Susan; Barras, Olivo; Richter, Daniel deB; Vandenberg, John JPotosí, 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.
