Farming on the margins : Just transition and the resilience of peripheral farms

2022

Sustainability transition demands fundamental changes taking place at the farm system level. At the same time, many farms are operating on the verge of financial profitability, especially in geographically disadvantaged peripheral regions with a limited range of production opportunities. These observations raise concerns about the transition's justice aspects. Using the concept of resilience, we analysed farmers’ capacities for transformation in a peripheral context in Finland. The results from our farmer survey (n = 577) indicated that the regime exerts a strong cost-price squeeze on farmers, escaping of which is difficult also for farmers deliberately seeking new pathways beyond it. Due t…

Suomalaisten maatilojen resilienssi osana tulevaisuuden ruokaturvaa

2017

Artikkelissa tarkastellaan maatilojen asemaa suomalaisen ruokaturvan kontekstissa. Maataloutta voidaan pitää haavoittuvaisena osana elintarvikejärjestelmässä. Sen vuoksi on tärkeää tarkastella sen asemaa kansallisen ruokaturvan takaajana. Selviytyäkseen maatiloilla täytyy olla resilienssiä eli kykyä mukautua väistämättä tapahtuviin muutoksiin. Artikkeli perustuu tutkimukseen, jossa haastateltiin 15 elintarvikejärjestelmän asiantuntijaa. Aineisto analysoitiin teoriasidonnaisella sisällönanalyysillä. Analyysissä on hyödynnetty Darnhoferin jaottelua maatilojen resilienssin ulottuvuuksista. Tutkimuksen tulosten mukaan maatalouden ongelmat liittyvät kannattavuuteen, sukupolvenvaihdosten onnistum…

Transitions through the dynamics of adaptive cycles : Evolution of the Finnish agrifood system

2023

CONTEXT The escalating sustainability problems of the current agrifood regime call for a radical, systemic transformation. Such a transformation implies a move into a new stability domain, defined by a new set of systemic attractors. These transformations can be conceptualised as regime shifts. OBJECTIVE In this study, we explored the history of the Finnish agrifood system in order to learn from the past transformations of the system and to inform the current attempts to steer its development in a more sustainable direction. METHODS We conducted a qualitative analysis on literature discussing the history of the Finnish agrifood system by utilising the concept of the adaptive cycle, which ca…

Synthesis, Electrochemistry, and Photophysics of Aza-BODIPY Porphyrin Dyes

2016

International audience; The synthesis of dyad and triad aza-BODIPY-porphyrin systems in two steps starting from an aryl-substituted aza-BODIPY chromophore is described. The properties of the resulting aza-BODIPY-porphyrin conjugates have been extensively investigated by means of electrochemistry, spectroelectrochemistry, and absorption/emission spectroscopy. Fluorescence measurements have revealed a dramatic loss of luminescence intensity, mainly due to competitive energy transfer and photoinduced electron transfer involving charge separation followed by recombination.

The Missing Member of the Partially O-Alkylated Resorcinarene Family: Synthesis and Conformation of Methyl Tetramethoxy Resorcinarene

2013

An improved Lewis acid catalyzed synthesis method for methyl tetramethoxy resorcinarene is described, which produced the missing lower rim methyl derivative of this partially O-alkylated resorcinarene family. Structural characterization by means of variable temperature NMR experiments and single crystal X-ray diffraction studies furthermore revealed that the resorcinarene core adopts different conformations in the solid state and in solution. peerReviewed

The Actuarial Balance Sheet for Pay-As-You-Go Finance: Solvency Indicators for Spain and Sweden

2008

This paper provides the first estimate of the actuarial balance of the Spanish contributory pension system for the old-age contingency, based on official data. The main accounting entries are developed from the principles of double-entry bookkeeping. The novel entry in the balance sheet, entitled the ‘contribution asset’ or ‘hidden asset’, is at the centre of the theoretical discussion. A comparison between the official balance sheet for the Swedish notional account system and our balance sheet for the Spanish contributory pension system is also provided. The main finding is that the Spanish pension system has an insolvency rate of 31.4 per cent. The policy implication is that unless curren…

The Effect of Mechanocatalytic Pretreatment on the Structure and Depolymerization of Willow

2020

In this study, the effect of a mechanocatalytic pretreatment on the structure of willow and sugar release from pretreated willow was explored. In the mechanocatalytic approach, the pretreatment consists of solvent-free impregnation with sulfuric acid and a mechanical treatment with ball milling. Willow sawdust and pretreated samples were analyzed with field emission scanning electron microscope and X-ray diffraction. The products in the sugar solution were determined as the total reducing sugars with the 3,5-dinitrosalicylic acid method and monosaccharides with capillary electrophoresis. According to the results, milling increased the sugar production, depending on the sulfuric acid load. T…

Comparison of Road Safety Policy Objectives in Poland and in the European Union

2016

The aim of the chapter is to identify main actions undertaken within the Polish road safety policy and to assess its efficacy based on the system approach, as well as to present recommendations for enhancing road safety in Poland. In the first part of the chapter key objectives of the EU road safety policy are elaborated. Then, the situation in Poland related to the number of road fatalities and to the causes of accidents is described, and policy instruments in Poland are presented. In the last part of the text an attempt is made to evaluate the Polish road safety policy. Besides, recommendations for improving road safety performance in Poland are elaborated on. In conclusion, it is stated …

Standardization of Road Danger Signs in the European Union

2015

The aim of this research is to find a solution for the standardization of road signs in the EU zone by a comparative analysis of different national sign systems to establish a common set from a single country. This work is based on the idea that road sign standardization might increase the safety level of transnational journeys and foster the relationships among the various members of the EU Community. This paper presents the outcome of the first step of the research, which focuses on the harmonization of danger signs. In more detail, a multicriteria approach is applied to rank 19 EU Member States on the basis of three main aspects: the installation cost of new signs, new sign learning issu…
