Small-scale hatcheries may have adverse effects on wild salmon, and the discourse between hatchery advocates and critics is heated. Despite this, they remain a widely used conservation tool. A new doctorate demonstrates that salmon hatcheries are important to the people and communities that operate them, and illuminate why efforts to limit or close them have been met with strong resistance.
A new doctorate has examined the multipurpose tree species African olive (Olea europaea subsp. cuspidata) in Tigray, Ethiopia. It is a vital resource to local communities, but is also threatened by overexploitation.
A new doctorate gives fresh insight into the socio-economic conditions of Ethiopian exclosures. Output is not divided equally amongst the locals, where rich households receive a bigger share. Local perceptions of them are largely favourable, however perception of the economic benefit is less compared to the ecological improvement.
PhD candidate Mengesteab Hailu Ubuy has studied the forest vegetation in the exclosures of Tigray, Ethiopia. He has provided data, models and insights that will be useful for the management of exclosures. He research shows that forest biomass loss over time in some cases is larger than the gain. A large part of this biomass loss is due to illegal harvesting, which is a threat for the prospects of sustainable development of the exclosures.
Human–nature conflicts poses a serious environmental challenge for human society. How to mitigate such conflicts and identify viable management options? Thursday December 20 there will be an open seminar relating to these issues. All are welcome.
A new NMBU project will create advanced population estimates for wolverines, wolves, and brown bears in Norway and Sweden. The project pioneers the combination of ecological knowledge, big data and statistical calculations.
PhD candidate David Ato Quansah has examined the performance of solar photovoltaic (PV) modules in Ghana. He found that they degraded at a faster rate than PV modules in Europe and North America, and consequently do not comply with typical industry warranties.
Soil contamination from airports in relation to de-icing of aircrafts pose a serious environmental challenge. A new dissertation from NMBU shows that non-invasive geophysical methods can monitor the degradation in the soil caused by organic contaminants, and a promising new lead may lessen the impact of soil degradation.
A new dissertation from NMBU shows that the feeding habits of the red deer changes the forest's plant and insect communities. Higher densities of red deer can potentially have major consequences on their surrounding ecosystems.
The combination of climate change and increased human population demands improved agricultural yields. There are ways to improve this productivity; but it is unlikely to combat hunger and malnutrition in Sub-Saharan Africa unless drastic adaptations are taken.
PhD candidate Artūrs Putniņš has reconstructed the evolution and retreat of the ice during the Last Ice Age in Gausdal Vestfjell, Norway. His work shows that there is much to be gained in using modern technology for landform mapping.
New research shows that papyrus plants contribute to the water storage capacity of floating papyrus wetlands. These results indicate that papyrus can be useful for irrigation of small-scale agriculture and improve production.
PhD candidate Franz Volker Mühle has examined the flow behind wind turbines with the aim of improving the layout and operation of wind farms. He found that limiting wind turbine wake effects significantly increases wind farm efficiency.
A new IUCN report shows that world palm oil production will have catastrophic effects on biodiversity if nothing changes. The authors say that a ban is not the way to go, and call for increased sustainability actions instead.
