Rapporten beskriver og dokumenterer inntektsvariasjon mellom ulike grupper gårdsbruk definert ved type produksjon, geografisk plassering og bruksstørrelse. I noen grad grad trekkes også inntekts-strukturen i husholdningen og inntektsvariasjon innen gruppe inn. I den grad det har vært mulig, er årsaker til inntektsvariasjon drøftet. I tillegg er usikkerheten i målingen av arbeidsforbruk i jordbru-ket vurdert. En begrensning i prosjektet er at en ikke har hatt informasjon om størrelsen av underskudd i jord-bruksnæring. Det en har hatt informasjon om er overskuddet når dette er positivt. Bare for samlet næringsinntekt er negative overskudd observert. Datagrunnlaget for analysen omfatter 6 926 husholdninger i SSBs landbruksundersøkelse 2018 der en personlig bruker er registrert med enkeltpersonforetak. Landbruksundersøkelsen inneholder blant annet tall for arbeidsforbruk i kalenderåret 2017. Disse er supplert med inntektsdata fra husholdning-enes selvangivelser (dvs. bruker, eventuell ektefelle/samboer/partner og andre familiemedlemmer med samme bostedsadresse) og detaljerte data om enkeltvekster og husdyr fra Landbruksdirektora-tets statistikk for produksjonstilskudd i jordbruket...

Integration of technology is commonplace in forestry equipment supporting higher levels of automation and efficiency. For technology adoption to be successful it must demonstrate improvement in productivity, cost–effectiveness or in human factors and ergonomics. Cable yarding lends itself to automation with repetitive machine movement along a fixed corridor, as established by the skyline. This study aimed at investigating the difference in productivity between the two possible settings (manual and automated) of a Valentini V850 yarder equipped with automatic path programming, with a Bergwald 3-t carriage and radio controlled chokers. The study took place in the northern Italian Alpine eastern region over a period of 8 days on two separate corridors, resulting in 280 measured cycles split between manual and automated. Results in terms of absolute numbers were very close for the two system options, but significant differences were found. For example, inhaul time was longer, but outhaul time shorter for the automated system. Productivity ranged from 8.2 to 13.3 m3 PMH-1, and cost from approximately 20 to 30 € m-3. The automated system did achieve a significantly higher productivity, but differences declined with extraction distance. When that was combined with the slightly higher cost for the automated system, the automated system was more cost-effective on extraction distances less than 200 m, and the manual system on longer distances.

Denne rapporten gjør en gjennomgang av kompetansebehovet i landbrukets verdikjeder, inkludert matindustrien. Det er også en oversikt og gjennomgang av utdanningstilbudene, fra videregående til universitet, som er rettet mot landbruket, samt søkning og kandidatproduksjon i disse. Til slutt i rapporten er det en gjennomgang av gap mellom kompetansebehov, utdanningstilbud og rekruttering, og forslag til tiltak.

This study aims to identify some of the critically important factors in the sustainability of microbreweries in peripheral northern areas, focusing on the entrepreneurs’ understanding of sustainability. Theoretically, this study adopts the perspective of service-dominant logic on value. Methodologically, it uses an action-research approach and conducts in-depth interviews with four entrepreneurs. The findings suggest that the entrepreneurs reflect on several relevant issues in line with sustainability thinking. The perception of sustainability, especially environmental sustainability, is one subject that the entrepreneurs perceive and sometimes in conflict with the economic sustainability of their businesses. Constraints recognized include the lack of strategic planning and explicit discussions about sustainability with potential stakeholders. A critically important factor for the sustainability of microbreweries is the need for entrepreneurs to engage in wider discussions about the conceptual and practical aspects of sustainability, especially with government and community bodies.

The site-specific nutrient management (SSNM) strategy provides guidelines for effective nitrogen, phosphorus and potassium management to help farmers make better decisions on fertilizer input and output levels in rice (Oryza sativa) production. The SSNM fertilizer recommendations are based on the yield goal approach, which has been frequently cited in empirical studies. This study evaluates the assumptions underlying the SSNM strategy for rice in the top rice-producing countries around the world, including India, Indonesia, the Philippines, Thailand, and Vietnam. Using a generalized quadratic production function, I explore whether major nutrients are substitutes as inputs and if there are complementarities between inorganic fertilizer and soil organic matter (SOM). The results suggest the relationships among major nutrients vary across sites—some inputs are complements, some are substitutes, and some are independent. The SOM also significantly affects the nitrogen fertilizer uptake. I conclude by suggesting that the SSNM strategy can be made to be more adaptive to farmer’s fields if these relationships are accounted for in the fertilizer recommendation algorithm.

This chapter emphasizes the need for active stakeholder engagement right through from strategy development to planning and implementation, to realize the benefits of sustainable bioeconomy development. In general, this varies between regions and countries. In the EU, it is considered important to engage stakeholders at all stages, whereas in developing countries engaging stakeholders so far has not been given much importance when launching new strategies. Stakeholders, including the private sector, research institutions, farmers organizations, the government and non-governmental organizations, all have important roles to play. The chapter focuses on the why, how and what type of stakeholders should be engaged, and the relevant benefits and challenges. It discusses experiences from the EU and other regions where stakeholder engagement (both formal and informal) and participative governance have led to or are necessary for successful and sustainable bioeconomy development.

In the last two decades, attention on forests and ownership rights has increased in different domains of international policy, particularly in relation to achieving the global sustainable development goals. This paper looks at the changes in forest-specific legislation applicable to regular productive forests, across 28 European countries. We compare the legal framework applicable in the mid-1990s with that applicable in 2015, using the Property Rights Index in Forestry (PRIF) to measure changes across time and space. The paper shows that forest owners in most western European countries already had high decision-making power in the mid-1990s, following deregulation trends from the 1980s; and for the next two decades, distribution of rights remained largely stable. For these countries, the content and direction of changes indicate that the main pressure on forest-focused legislation comes from environmental discourses (e.g. biodiversity and climate change policies). In contrast, former socialist countries in the mid-1990s gave lower decision-making powers to forest owners than in any of the Western Europe countries; over the next 20 years these show remarkable changes in management, exclusion and withdrawal rights. As a result of these changes, there is no longer a clear line between western and former socialist countries with respect to the national governance systems used to address private forest ownership. Nevertheless, with the exception of Baltic countries which have moved towards the western forest governance system, most of the former socialist countries still maintain a state-centred approach in private forest management. Overall, most of the changes we identified in the last two decades across Europe were recorded in the categories of management rights and exclusion rights. These changes reflect the general trend in European forest policies to expand and reinforce the landowners’ individual rights, while preserving minimal rights for other categories of forest users; and to promote the use of financial instruments when targeting policy goals related to the environmental discourse.
