1. Investigating the state of rural water supply in Rio Grande do Sul, Brazil - a regional study on the implementation of United Nations Sustainable Development Goal 6.1: safe and affordable drinking water for all
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Access to clean drinking water is a human right and a necessity for life, yet many rely on precarious water sources across the world. The United Nations outlines a great aspiration in Agenda 2030 - that safe and affordable drinking water should be available for all by 2030. LÄS MER
2. (Bee)coming Revolution: an environmental study with local beekeepers in Rio Grande do Sul, Brazil
Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historiaSammanfattning : In this thesis I study how the relationships between beekeepers and bees have evolved over time in the region of Rio Grande do Sul, Brazil and how the beekeepers have experienced the environmental changes in this region over time.

5. Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.
Kandidat-uppsats, Högskolan i Halmstad/Sektionen för ekonomi och teknik (SET)Sammanfattning : A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes.
