Dissolved and colloidal phases responsible for arsenic mobilization in the Mekong Delta in Vietnam (MDVN)

 
Rizlan BERNIER-LATMAMNI (ENAC – EML

 Arsenic contamination of the groundwater in the Mekong River Delta in Vietnam is a significant issue as it affects drinking water supply, agriculture and industry. Based on available geochemistry data, we have formulated two hypotheses to explain the release of arsenic from sediment into groundwater. This project is designed to seek experimental evidence for these two hypotheses in the field by sampling groundwater, soil, river water and sediments and analyzing the samples at EPFL and in Vietnam.

Behaviour of antibiotics from shrimp farms in the aquatic system in Vietnam (BASFAS)

 Felipe DE ALENCASTRO (ENAC – CEL) Denis GILLET (STI – SCI-STI-DG)

This study taking place in Southern Vietnam concerns the presence and impact of antibiotics in shrimp farms, the effects of their discharges on the quality of water and sediments of rivers,
as well as the risks of resistance to antibiotics and the effects of physico-chemical properties of the environment and the metals on the adsorption and desorption of antibiotics in the sediment.

SenseCityVity: Mobile sensing and collective action for urban awareness in Mexico

Daniel GATICA-PEREZ (STI – LIDIAP)

The state of urban environments in developing countries is associated with challenges in sustainable development, poverty reduction, and wellbeing. Empowering citizens through the use of technologies and methodologies leading to social awareness and understanding of urban dynamics is of prime importance. SenseCityVity aims at validating the feasibility of design and rapid deployment of mobile participatory sensing / crowdsourcing technologies to address urban concern by youth populations in México.

Impact of transportation and mobility on the urban development of Havana

 François GOLAY (ENAC – LASIG

 The project aims at optimizing transportation scenarios to reduce energy consumption and human health impacts in Havana. Technological, urban development and mobility scenarios will be considered, and a measurement network will be set up to monitor the impacts of the implemented measures. Workshops are organized to support the teamwork and collaborative action between CUJAE, UNAL and EPFL.

Design of a practical solar-assisted CO2 capture system

Sophia HAUSSENER (STI – LRESE

 Finding a balance between economic growth and preservation of the environment is a major challenge, especially for emerging countries such as China where air quality has decreased and CO2 emissions have increased significantly over the past 20 years. A practical and efficient solar-assisted CO2 capture system will be designed and its performance will be investigated using different CO2 sources. A comparative technical evaluation of integrated, solar-assisted, and conventional carbon capture and storage systems will be presented in terms of potential, feasibility and cost.

BIO-DESIGN for the REAL WORLD: An experiment in studentdriven handson research and international collaboration (BIODESIGN)

 Sachiko HIROSUE (SV – IBI)

 This trans- and interdisciplinary project aims at empowering communities to analyze quality of water using Do-It-Yourself (DIY) / Do-It-With-Others (DIWO) approach to open hardware, and mapping of results. Our collaboration between Switzerland (EPFL – bachelor projects), India ((art) ScienceBLR – art science students) and Indonesia (Lifepatch – citizen science) is a co-creation model, where agency rests in each partner, based on DIY and Open sharing approaches, with strong local ties to research universities. We focused on arsenic and coliform bacteria detection.

Near realtime ultrahighresolution imaging from unmanned aerial vehicles for sustainable land use management and biodiversity conservation in semiarid savanna under regional and global change (SAVMAP)

 Stéphane JOOST (ENAC – LASIG)

 To prevent aggravation of existing poverty in semiarid savannas, a concept for sustainable management and use of these ecosystems under unprecedented conditions is needed. SAVMAP is an innovative, interdisciplinary initiative whose goal is to develop a monitoring tool for both sustainable landuse management and rare species conservation (black rhinoceros) in semiarid savanna in Namibia. SAVMAP uses near realtime ultrahighresolution imaging (NURI) facilitated by unmanned aerial vehicles (UAVs) designed at EPFL.
