Estimates of emissions and removals resulting from activities under article 3.3 and 3.4 of the Kyoto Protocol
(Oppdragsrapport fra Skog og landskap;2-2006, Research report, 2006)As a party to the Kyoto Protocol, Norway will be required to report its emissions by sources and removals by sinks of CO2 and other greenhouse gases resulting from afforestation, reforestation and deforestation (Article ... -
Estimating and managing broad risk of chronic wasting disease spillover among cervid species
(Peer reviewed; Journal article, 2023-09-10)The management of infectious wildlife diseases often involves tackling pathogens that infect multiple host species. Chronic wasting disease (CWD) is a prion disease that can infect most cervid species. CWD was detected in ... -
Estimating Carbon Sink Strength of Norway Spruce Forests Using Machine Learning
(Peer reviewed; Journal article, 2022-10-19)Forests sequester atmospheric carbon dioxide (CO2) which is important for climate mitigation. Net ecosystem production (NEP) varies significantly across forests in different regions depending on the dominant tree species, ... -
Estimating local-scale forest GPP in Northern Europe using Sentinel-2: Model comparisons with LUE, APAR, the plant phenology index, and a light response function
(Peer reviewed; Journal article, 2023-01-03)Northern forest ecosystems make up an important part of the global carbon cycle. Hence, monitoring local-scale gross primary production (GPP) of Northern forest is essential for understanding climatic change impacts on ... -
Estimating stand level stem diameter distribution utilizing harvester data and airborne laser scanning
(Journal article; Peer reviewed, 2019-08-07)Accurately positioned single-tree data obtained from a cut-to-length harvester were used as training harvester plot data for k-nearest neighbor (k-nn) stem diameter distribution modelling applying airborne laser scanning ... -
Estimating the Permeability of Naturally Structured Soil From Percolation Theory and Pore Space Characteristics Imaged by X-Ray
(Journal article; Peer reviewed, 2018-10-30)The saturated hydraulic conductivity of soil, Ks, is a critical parameter in hydrological models that remains notoriously difficult to predict. In this study, we test the capability of a model based on percolation theory ... -
Estimating unconsolidated sediment cover thickness by using the horizontal distance to a bedrock outcrop as secondary information
(Journal article; Peer reviewed, 2017)Unconsolidated sediment cover thickness (D) above bedrock was estimated by using a publicly available well database from Norway, GRANADA. General challenges associated with such databases typically involve clustering and ... -
Estimating yearly numbers of animals, and enteric methane emissions, for pigs. Methodologies for the Norwegian national inventory of GHG emissions
(NIBIO Rapport, Research report, 2022)Commissioned by the Norwegian Environment Agency, this report presents methodologies for estimating annual numbers of animals and enteric methane emissions for pigs. The methodologies are designed for the Norwegian national ... -
Estimation of Forest Growing Stock Volume with UAV Laser Scanning Data: Can It Be Done without Field Data?
(Peer reviewed; Journal article, 2020-04-14)Laser scanning data from unmanned aerial vehicles (UAV-LS) offer new opportunities to estimate forest growing stock volume ( V ) exclusively based on the UAV-LS data. We propose a method to measure tree attributes and using ... -
Estimation of phosphorus-based flame retardant in wood by hyperspectral imaging—a new method
(Journal article; Peer reviewed, 2018-02-15)It is recognised that flame retardant chemicals degrade and leach out of flame-protected wood claddings when exposed to natural weathering. However, the ability to survey the current state of a flame retardant treatment ... -
Estimation of water use for irrigation in Norwegian agriculture
(Bioforsk rapport;4(174) 2009, Research report, 2009-08)The report presents model simulations of irrigation water requirements over the period 1973-2008 for various crops in four regions of Norway. A detailed summary in English is given on pp. 47-49. -
