Article
Distributional fairness concerns are key barriers to the implementation of climate policies. Emission rights allocation is the decisive distributional feature of personal carbon trading (PCT) that is intended to incentivise individuals' low-carbon choices. The aim of the current study was to identify the predictors of the perceived distributional f...

Agriculture and food production are usually based on family farms or family enterprises. During the past decades, high job demands and mental health problems among farmers have been emerging issues. Lack of social support, high workload, ill health, and burnout among farmers may have serious direct and indirect negative consequences to the well-bei...
Article
Personal carbon allowances have been of considerable interest in environmental research in the last decade, yet no policy implementations have been adopted, partly due to uncertainty around the political acceptability of equal allowances. We tackled this issue by surveying public perceptions of fairness in carbon allowance allocation in urban mobil...

Global agriculture faces severe challenges due to climate change. For boreal agriculture, climate change might also bring opportunities as the growing season lengthens, if the risks of climate change are managed properly. Agricultural production is a source of greenhouse gases, while agricultural land has also a great possibility to mitigate climat...

Agroforestry has the potential to sequester carbon (C) and nitrogen (N), thereby counteracting climate change and soil degradation. However, the lack of empirical quantitative evidence on determinants of C and N stocks hampers the management of these stocks. The aim of this study was to identify the key determinants of the C and N stocks in multist...

Monocropping of perennial cash crops providing livelihood for smallholders is replacing native forest throughout the tropics, but there is no direct empirical evidence on the impact on soil organic carbon (SOC) and nitrogen (N) relative to multistrata-agroforestry-based cash cropping. In particular, the impact of the conversion of forests and multi...

The pyroligneous acids (PAs) of woody biomass produced by torrefaction have pesticidal properties. Thus, PAs are potential alternatives to synthetic plant protection chemicals. Although woody biomass is a renewable feedstock, its use must be efficient. The efficiency of biomass utilization can be improved by applying a cascading use principle. This...

Purpose Charred materials are low in bioavailable nitrogen (N) due to gaseous losses and the formation of recalcitrant structures during pyrolysis. Enriching chars with N from wastewaters offers a possibility to upgrade the agronomic value of the chars and manage the liquids. For assessing the practical feasibility of the approach, more information...
Article
At high latitudes of Europe climate change is projected to alter the risk of flooding and drought depending on the season. Farmers are the ones who decide how and when to adapt to excess, scarcity, and even to extreme precipitation events in agriculture. To understand farmer’s views on the needs and means to manage future changes in precipitation,...
Article
Novel bioeconomic approaches call for increasingly faster production of lignocellulosic biomass and its better-tailored use for higher added value. The high-yield capacity and structural properties of willows (Salix spp.) suggest their excellent potential for the production of designed biochar for use in agronomic, electronic and technical applicat...

Developing shoots, i.e., sprouts, and older needles of Norway spruce (Picea abies (L.) Karst.) have traditionally been used for medicinal purposes due to the high content of vitamins and antioxidants. Currently, sprouts are available as, for example, superfood and supplements. However, end-product quality and nutritive value may decline in the valu...

Soil hydraulic properties play an important role in determining the level of crop productivity and the extent of environmental loading. Consequently, measurement of near-saturated soil hydraulic conductivity (K(h)) by tension infiltrometer (TI) is an interesting technique. To provide reference values for near-saturated K(h) in arable mineral topsoi...
Presentation
Climate change challenges agriculture but can also benefit boreal agriculture with proper risk management. Agriculture has a dual role in climate change mitigation; it is a source of greenhouse gases but also a sink for carbon. Policies steer the transition to aimed direction, but farmer is the core actor in both adaptation and mitigation. Hence, f...

By processing large quantities of crop residues, earthworms enhance the mineralization of organic matter but have also been shown to stabilize soil organic carbon (SOC) into soil fractions like microaggregates (53–250 μm) within macroaggregates (>250 μm) especially in no-till soils. Our objective was to find direct evidence on the impact of an anec...

Significance Food security under climate change depends on the yield performance of staple food crops. We found a decline in the climate resilience of European wheat in most countries during the last 5 to 15 y, depending on the country. The yield responses of all the cultivars to different weather events were relatively similar within northern and...
Presentation
Strong scientific proof supports anthropogenic climate change and also shows that the pace of change has accelerated. Mitigation actions have not yet been able to curb emission trends globally. Agriculture constitutes around 10 % of the greenhouse gas (GHG) emissions in Europe without land use, land use change and forestry (LULUCF) sector emissions...

Methods: A postal survey yielded 265 completed questionnaires from 188 dairy farms. The sample was assessed as representative of Finnish dairy farmers. Expl...
Conference Paper
Grass growth models that describe the development of grass digestibility (D-value, g kg-1 DM) at the first silage cut are widely used in Finland for optimal timing of harvests, due to the rapid decline in D-value prior to the optimal harvest stage. However, the models need to be improved in order to provide estimates of D-value and dry matter (DM)...

The new EU CAP, Paris climate targets, weather variability and other climate change impacts pose new challenges to agricultural production in Finland. Future studies in agriculture have focused on scenario building with expert panels, in most cases leaving farmers outside the process. I will present farmer led scenarios on the future of Finnish agr...
Article
Soil carbon (C) represents the largest terrestrial carbon stock and is key for soil productivity. Major fractions of soil C consist of organic C, carbonates and black C. The turnover rate of black C is lower than that of organic C, and black C abundance decreases the vulnerablility of soil C stock to decomposition under climate change. The aim of t...

In addition to causing shifts in regional climate, climate change will also affect the combination of climatic conditions and dominant soil type. This may be reflected in crop responses; however, currently, empirical knowledge in this regard is limited. We hypothesised that 1) the weather patterns most influencing forage crop yield variation vary a...
