    Forests, forestry and the water framework directive in Sweden: a trans-disciplinary commentary2011Ingår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 2, nr 1, s. 261-282Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Water Framework Directive (WFD) is an ambitious piece of legislation designed to protect and improve water quality throughout Europe. However, forests are only mentioned once in the WFD, and forestry is not mentioned at all, despite its potential implications for streams, rivers and lakes. Here we present a transdisciplinary commentary on the WFD and its implications for forests and forestry in Sweden. This commentary has been prepared by forestry stakeholders, biophysical and social scientists. While we were cognizant of a large body of discipline-specific research, there are very few inter- or trans-disciplinary commentaries which link academic and stakeholder perspectives on the WFD. We had originally felt that there would be little commonality in our concerns. However, we found significant areas of agreement. Our key areas of concern about the implications of the WFD for forestry in Sweden included: (i) concerns about what is meant by good ecological status and how it is assessed; (ii) a perceived lack of clarity in the legal framework; (iii) an inadequate environmental impact assessment process; and (iv) uncertainties about appropriate programs of measures for improving water quality. We were also concerned that ecosystem services provided by forests and the positive effects of forestry on water quality are inadequately recognized in the WFD.

    Dynamics of Timber Market Integration in Sweden2015Ingår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 6, nr 12, s. 4617-4633, artikel-id 17Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper addresses the performance of the timber markets (Scots pine, Pinus silvestris L. and Norway spruce, Picea abies (L.) Karst.) by evaluating the order of market integration in three Swedish regions (Central, Northern, and Southern). Quarterly data of delivery prices are employed over the period 1999Q1–2012Q4. Various unit root and cointegration tests have been computed. The results indicate that the variables are integrated of first order and co-integrated, especially after controlling for structural breaks. This supports the law-of-one-price hypothesis (LOP). However, the effects of structural shocks on forestry are arguably significant and these are controlled for while performing a vector error-correction mechanism (VECM)-based Granger-causality test. Bi-directional causality between the Northern and central markets is uncovered in the short-run. In the long-run, a similar causal effect is detected between Northern and Southern markets while the central market emerges as the price leader. Further investigation is carried out using variance decompositions and impulse response functions and these approaches also tend to confirm the existence of a single market well, as price interdependence between markets.

    Dynamics of Wood Pulp Production: Evidence from OECD Countries2017Ingår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 8, nr 4, s. 170-180, artikel-id 107Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper investigates whether shocks to pulp for paper production for 17 Organisation for Economic Co-Operation and Development (OECD) members over the period 1980–2012 are transitory or permanent. A variety of univariate and panel data unit root tests are employed. The presence of structural breaks is taken into account when performing those tests. Based on the Narayan-Popp univariate unit root test, wood production series for approximately 64.71% of countries is found to follow a non-stationary process. However, univariate unit root tests tend to have low power when the time span is relatively short. Consequently, three generations of panel unit root tests are considered. Cross-sectional dependence is detected. The first generation of unit roots do not effectively control for cross-sectional dependence, while the second and third generations do. The third generation accounts mainly for cross-sectional co-integration. As a confirmatory analysis, both unit root tests that tests for the null of non-stationarity and stationarity are considered. Most of the panel unit root tests point towards a non-stationary process. Hence, while these shocks can be transmitted to other economic sectors, past behaviours of wood production cannot be used for forecasting purposes. Forest conservation policies can have a permanent impact on pulp for paper production.

    Food, Paper, Wood, or Energy?: Global Trends and Future Swedish Forest Use2011Ingår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 2, nr 1, s. 51-65Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper presents a futures study of international forest trends. The study, produced as part of the Swedish Future Forest program, focuses on global changes of importance for future Swedish forest use. It is based on previous international research, policy documents, and 24 interviews with selected key experts and/or actors related to the forest sector, and its findings will provide a basis for future research priorities. The forest sector, here defined as the economic, social, and cultural contributions to life and human welfare derived from forest and forest-based activities, faces major change. Four areas stand out as particularly important: changing energy systems, emerging international climate policies, changing governance systems, and shifting global land use systems. We argue that global developments are, and will be, important for future Swedish forest use. The forest sector is in transition and forest-, energy, climate- and global land use issues are likely to become increasingly intertwined. Therefore, the “forest sector” must be disembedded and approached as an open system in interplay with other systems.

    Application of GRAS Compounds for the Control of Mould Growth on Scots Pine Sapwood Surfaces: Multivariate Modelling of Mould Grade2019Ingår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 10, nr 9, artikel-id 714Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Research Highlights: In this study, the Generally Recognised as Safe (GRAS) compounds were applied in order to study mould-fungi growth on dried Scots pine sapwood. Background and Objectives: The transition to the use of more sustainable wood-material may be possible by applying GRAS compounds that can control and prevent contamination by primary colonising mould fungi. Materials and Methods: Kiln-dried sawn timber was treated with three different GRAS compounds, and different fungal inoculation methods applied in order to investigate differences in the development of fungal communities. Results: Substances based on potassium silicate significantly reduced fungal growth and mould contamination on the studied wood surfaces. By combining wood-surface treatments with GRAS compounds, fungal-area size as predictors and mould grade as response, a partial least squares (PLS) model that makes it possible to predict mould grade on wood surfaces was developed. The PLS model is a key component in the development of a smart grading-systems equipped by e.g. high-speed digital cameras for the early detection of fungal attack on wood surfaces in different applications. However, the measurements based on chemical characterisation should be the next step to take in order significantly to enhance the model and increase the range of robust applications. In the current study, a multivariate model describing the influence of each fungal-covering area on mould grade was presented for the first time.

    Estimating the annual above-ground biomass production of various species on sites in Sweden on the basis of individual climate and productivity values.2014Ingår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 5, nr 10, s. 2521-2541Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The literature contains a large number of bioclimate, climate and biometric models for estimating the production of different species or stands under specific conditions on a defined site or models giving the distribution of a single species. Depending on the model used, the amount of input data required varies considerably and often involves a large investment in time and money. The purpose of this study was to create a model to estimate the annual above-ground biomass production of various species from site conditions defined by mean annual temperature and mean annual precipitation. For this approach, the Miami model of Lieth was used as a base model with some modifications. This first version of the modified model was restricted to sites in Sweden, where changes in the soil and groundwater level were relatively small, and where the growth of land vegetation was mostly dependent on temperature. A validation of this model has shown that it seems possible to use the Miami model to estimate the annual above-ground biomass production of various species, and that it was possible to compare the annual above-ground biomass production of different species on one site, as well as the annual above-ground biomass production of different species on different sites using the modeled data.
