Distinguishing between Sources of Natural Dissolved Organic Matter (DOM) Based on Its Characteristics
Vogt, Rolf David; Porcal, Petr; Hejzlar, Josef; Paule‐Mercado, Ma. Cristina; Haaland, Ståle Leif; Gundersen, Cathrine Brecke; Orderud, Geir Inge; Eikebrokk, Bjørnar (Peer reviewed; Journal article, 2023)Increasing levels of dissolved organic matter (DOM) in watercourses in the northern hemisphere are mainly due to reduced acid rain, climate change, and changes in agricultural practices. However, their impacts vary in time ... -
Environmental values and attitudes among farmers in China – a case study in the watershed of Yuqiao reservoir of Tianjin Municipality, China
Orderud, Geir; Vogt, Rolf David (Journal article; Peer reviewed, 2016)Failure to curb water pollution in China brings to the fore the issue of environmental values and attitudes among Chinese farmers. Applying the New Ecological Paradigm Scale this study finds that the pro-environmental value ... -
Explaining and understanding environmental actions in Chinese agriculture: the case of Yuqiao watershed of Tianjin municipality
Orderud, Geir; Vogt, Rolf David; Andersen, Tom; Luo, Jing (Journal article; Peer reviewed, 2015)Most of China’s surface waters are undergoing anthropogenic eutrophication, mainly due to leaching of phosphorus (P) from both sewage and agriculture. This is causing quality deterioration in their scarce water resources. ... -
Interdisciplinary research and transdisciplinary processes for environmental management under different socio-natural conditions
Orderud, Geir; Vogt, Rolf David; Tan, Hongze; Luo, Jing (International Journal of Environmental Studies;Volume 75 - Issue 5, Journal article; Peer reviewed, 2018-01-08)Interdisciplinary research and transdisciplinary processes as part of environmental management respond to the increasing complexity of socio-natural changes in recent decades. Two similar studies of eutrophication in raw ... -
Predicting the dissolved natural organic matter (DNOM) concentration and the specific ultraviolet absorption (sUVa) index in a browning central European stream
Haaland, Ståle Leif; Hejzlar, Josef; Eikebrokk, Bjørnar; Orderud, Geir; Paule‐Mercado, Ma. Cristina; Porcal, Petr; Sláma, Jiří; Vogt, Rolf David (Peer reviewed; Journal article, 2024)Over the past four decades, an increase in Dissolved Natural Organic Matter (DNOM) and colour, commonly referred to as browning, has been noted in numerous watercourses in the northern hemisphere. Understanding the ... -
The Role of Information and Knowledge in Achieving Environmentally Sound Farming: A Chinese Case
Orderud, Geir; Vogt, Rolf David; Tan, Hongze; Luo, Jing (Journal article; Peer reviewed, 2017)The paper analyzes the role of information–knowledge for making farming environmentally friendly, using eutrophication of the main drinking water reservoir of Tianjin, China as a case. The analysis considers information ... -
Trans-disciplinarily required in understanding, predicting and dealing with water eutrophication
Orderud, Geir; Vogt, Rolf David (Journal article; Peer reviewed, 2013)Eutrophication remains a challenge for water quality, and leaching of phosphorus (P) from agriculture remains usually the determining factor as point source emissions of sewage are mainly under control. The Morsa watershed, ...
