Science Blog: The secrets lake sediments have to share: Urbanization caused of low oxygen conditions in European lakes

Text:
Antti Ojala, Senior Scientist

A new study shows that hypoxia, i.e. low oxygen conditions, in European lakes started in 1850, becoming more widespread after 1900, long before the use of chemical fertilizers and climate change. A Canadian and European research team has identified urban expansion as the reason for the low amounts of bioavailable oxygen in numerous European lakes […]

Kaisa Turunen, Planner

Arsenic (As) is a ubiquitous metalloid that is found in low concentrations in the atmosphere, in aquatic environments, in soils and sediments, and in organisms. Its presence in the environment can be due to natural processes, such as weathering, biological, and volcanic activity, or anthropogenic activities such as mining. As is problematic because of its […]

Improving the food security of Ethiopia through geosciences

Text:
Chernet Tegist, Senior Research Scientist

Along with an ever increasing population, the vast soil degradation due to soil acidity causing insufficient crop production appears to be a substantial challenge facing Ethiopia. Based on lessons learned and experiences gained from a previous project (2014-2015), this project is scaling up the lime resource survey and farm trials focusing on the Oromia Region, […]
