Résumé Anopheles de Bolivie : Nouveaux signalements avec une liste d’espèces actualisée et commentée. Anopheles squamifemur a été identifié à partir de collectes faites avec des pièges lumineux de type CDC à Arca de Israel, une petite communauté située à l’extrême nord-est de la Bolivie (Département de Pando) sur les rives du fleuve Madera, à la frontière avec le Brésil. Anopheles costai et An. forattinii ont été identifiés en lieu et place d’An. mediopunctatus qui est supprimé de la liste des Anopheles de Bolivie. La première identification d’An. trinkae en Bolivie par le Dr. J.C. Lien en 1984 est précisée. La présence d’An. deaneorum en Bolivie a été confirmée par nos captures effectuées à Guayaramerín (Département de Pando, nord-est de la Bolivie), une ville frontière séparée de la localité type d’An. deaneorum (la ville brésilienne de Guajara-Mirin) par le grand fleuve Mamoré.

  • Improving Productivity of Small Peri-Urban Farmers by Bio-Rational Soil Management
    Improving Productivity of Traditional Andean Small Farmers by Bio-Rational Soil Management: I. The Potato Case J. Franco; G. Main; O. Navia, N. Ortuño and J. Herbas1 Summary The use of chemical pesticides in agriculture demands high investments; its in discriminated and inadequate application to obtain immediate crop response has caused considerable damage to the environment and human health, either due to a direct effect or indirect contamination of farmer fields and water sources by highly toxic products. On the other hand, as a result of soil fertility losses, farmers move to new areas for farming, causing a complex migration phenomena and devastation of natural forests. In an effort to find new alternatives for the management of crop pests compatible with the environment and agro- ecologically friendly, some technologies recently developed have been offered to small Andean potato farmers. Among these, the recycling of organic residues and the management of natural soil microorganisms which are important alternatives to reduce the importation and use of toxic agro-chemicals as well as to preserve and recuperate soil fertility and thus reach a sustainable potato production by Andean farmers. This will not only guarantee food security, but will also have favorable impact on the yield and quality of potato and other crops.

  • Anatomy of a Regional Conflict: Tarija and Resource Grievances in Morales
    Anatomy of a regional conflict: Tarija and resource grievances in Morales’ Bolivia Denise Humphreys Bebbington School of Environment and Development Room 1.54, Humanities Bridgeford Street University of Manchester Oxford Road Manchester, M13 9PL UK [email protected] Tel 44-1457-869813 Anthony Bebbington School of Environment and Development Room 1.54, Humanities Bridgeford Street University of Manchester Oxford Road Manchester, M13 9PL UK [email protected] Tel: 44-161-2750422 Forthcoming in Latin American Perspectives , 2010 Abstract: In 2008, the Department of Tarija became the epicenter of national political struggles over political autonomy for lowland regions at odds with the Morales administration. In September, following a series of regional referenda on autonomy and a national recall election, citizen committees in Tarija mobilized urban-based sectors and organized a general strike to oppose central government. This paper analyzes this mobilization and argues that it is unhelpful to understand the strike as simply an act of political sabotage orchestrated by racist, regional elites. The factors driving protest and interest in autonomy are varied and deeply related to patterns of hydrocarbon extraction in the department that have allowed for the mobilization of grievance and cultivation of resource regionalism at departmental and intra-departmental scales. Theoretically it suggests that alongside class and ethnicity, identities of place and region can be equally important in processes of mobilization,

  • Quantifying Deforestation Rates in a Cocaine Source Region in Bolivia: a Study to Verify Rates of Land-Use Change Under Pro-Coca Policies
    Quantifying deforestation rates in a cocaine source region in Bolivia: A study to verify rates of land-use change under pro-coca policies Thesis submitted by Edmond NAGOMBI (BSc, PNG UNITECH, BEng, PNG UNITECH) June 2017 For the degree of Masters of Science in GIS In the School of Environment, Faculty of Science and Engineering Flinders University, Adelaide, South Australia i Abstract This thesis focuses on humid tropical deforestation in one of the most important coca growing regions in central Bolivia, Chapare. On the one hand, the cultivation of coca leaves which is the source of cocaine paste, their processing and narcotrafficking are global, social and legal issues that lead to violence, corruption, and instability in foreign policy frameworks. On the other hand, their cultivation has local environmental and economic repercussions that are not always negative. The project is grounded in geospatial science and the methodology comprises of three main sections: image pre-processing, land-use and land-cover classification aimed at forest/non-forest mapping, and the generation of forest and non-forest statistics for individual farms in four communities in Chapare. Landsat 4 & 5 (TM) (2011) and Landsat 8 (OLI) satellite (2015 and 2016) image data were used. Pre- processing steps covered verification of geometric and radiometric parameters, image mosaicking and, for the 2015 data, pan sharpening. Thus, the images were classified using unsupervised classification to map major land-use and land-cover types from 2015 imagery. These were verified with reference to field data collected in 2015 that was made available to this research project. Forest and non-forest classification was carried out for the 2011, 2015 and 2016 image data.

  • Floods Update N° 1 26 March 2010
    DREF operation n° MDRBO005 GLIDE n° FL-2010-000008-BOL Bolivia: Floods Update n° 1 26 March 2010 The International Federation’s Disaster Relief Emergency Fund (DREF) is a source of un-earmarked money created by the Federation in 1985 to ensure that immediate financial support is available for Red Cross and Red Crescent emergency response. The DREF is a vital part of the International Federation’s disaster response system and increases the ability of National Societies to respond to disasters. Period covered by this update: 13 February 2010 to 13 March 2010. Summary: 146,723 Swiss francs (137,604 US dollars or 99,995 euros) have been allocated from the Federation’s Disaster Relief Emergency Fund (DREF) to support the Bolivian Red Cross (BRC) in delivering immediate assistance to some 1,500 families (approximately 7,500 people). Un-earmarked funds to repay DREF are encouraged. Severe rainfall since September 2009 has caused floods and mudslides in Bolivia. The The Bolivian Red Cross worked together with local authorities to distribute Bolivian Civil Defence’s emergency relief. Source: Bolivian Red Cross assessments have reported the departments of Beni, Cochabamba, Chuquisaca, La Paz and Santa Cruz have been severely affected. To date, the Bolivian Red Cross has distributed food and non-food items to 1,200 families in the department of Cochabamba. This operation is expected to be implemented over three months, and will therefore be completed by 11 May 2010 a Final Report will be made available three months after the end of the operation (by 11 August 2010). The Canadian government through the Canadian Red Cross contributed 30,000 Canadian dollars (29,990 Swiss francs) and the European Commission Humanitarian Aid Office (ECHO) contributed 79,996 euros (116,733 Swiss francs) to the DREF in replenishment of the allocation made for this operation.

Analyzing recent economic, political, and territorial transformations of Bolivia’s gas-rich region, Tarija, we argue that pre-existing territorial projects of a diverse set of subnational and national actors have: (i) shaped the influence of the gas industry on local dynamics; (ii) changed the scale relationships between local communities, the state, and companies; and (iii) mediated the transformation of territories in ways determined by the nature and aspirations of these territorial projects.
