1. Anaerobic Digestion of Solid Residues on the Bolivian Altiplano
Sammanfattning : Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. LÄS MER
2. Hydrogeochemistry and spatial variability of arsenic and other trace elements in the Lower Katari Basin around Lake Titicaca, Bolivian Altiplano. : Impact on drinking water quality and groundwater management
Sammanfattning : Arsenic (As) contamination in drinking water is a world-wide problem. Thenatural origin of As, its mobility and transport are of great interest in BolivianAltiplano (Lower Katari Basin: LKB and Sothern Poopó Basin: SPB) due topresence of mineral ore deposits, brines, hot springs and volcanic rocks.

3. Patrones de Asentamiento Precolombino del Altiplano Boliviano : Lugares Centrales de la Región de Quillacas, Departamento de Oruro, Bolivia
Sammanfattning : Archaeology in Bolivia has two strong tendencies: nationalism and regionalism. The proposal aims for an academic reconstruction and expansion of this science in order to develop new scientific criteria, that can be institutionalized and become normative to the whole country to cover the expectations of different regions with regard to its past.

4. Geochemistry of Trace Elements in the Bolivian Altiplano : Effects of natural processes and anthropogenic activities
Sammanfattning : The occurrence of As in groundwater in Argentina was known since 1917; however, the occurrence, distribution and mobilization of As and other trace elements (TEs) in groundwater in the Bolivian Altiplano are still quite unknown. An investigation applying a geochemical approach was conducted in the Poopó Basin and Lake Titicaca to understand processes of TEs in different systems such as water, soils, crops and sediments in mining areas.

5. Water Resources Management efforts for best water allocation in the Lake Poopo basin, Bolivia
Sammanfattning : The Lake Poopo basin, located on the Bolivian Altiplano, is extremely vulnerable to environmental degradation. The basin displays extreme spatial and temporal variations of water resources and rapidly decreasing water quality due to anthropogenic and natural pollution. LÄS MER
