1. Environmental Effects of Agricultural Expansion in the Upper Amazon : A study of river basin geochemistry and hydrochemistry, and farmers' perceptions
Sammanfattning : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.

The focus of the thesis is groundwater recharge and dry season flow following deforestation and land degradation. LÄS MER
3. Impacts of climate oscillation on precipitation and river flows of small scale river basins in Eastern Northeast Brazil
Sammanfattning : The Northeast region of Brazil is one of the most susceptible parts of the country to the effects of climate variability leading to severe droughts or extreme floods. Indeed, drought is a major issue due to a large semiarid area that covers 53% of the region, which determines the main climate characteristics of this region. LÄS MER
