A grand societal challenge arises from an ageing population. Central governments respond by issuing an innovation imperative targeted at local municipalities as a major instrument to form a sustainable welfare sector policy. The presentation studies policies relating to one particular form of care innovation in the field of dementia care, in particular day care services provided by farmers – Farm Based Dementia Care – FBDC. The intention is to explore potential barriers to increased use of FBDC and the relevance of the current policy mix. Barriers are derived from innovation theory, theory of transaction costs, regulation and societal transformation. Observations from municipalities applying FBDC are used to understand the relevance of potential barriers. Relevant barriers are compared with the diversity of policies aiming to impact dementia care directly or indirectly, e.g. through general innovativeness at municipal level. Empirical observations are based on in-depth, semi-structured interviews with seven municipalities, complemented by contributions at workshops and previous analysis. When compared with the panel of policy measures and initiatives taken in order to make elderly care match future challenges from shifting demographics, we may identify strengths and weaknesses of policy aimed to manage the grand challenges arising from an ageing population.

The aim of this work was to investigate whether the agronomic traits of vermicompost prepared from partially stabilised sewage sludge digestate after thermophilic composting were more favourable than those of conventional compost. The effects of various additives (green waste, spent mushroom compost, wheat straw, biochar) were also tested after 1.5 months precomposting followed by 3 months vermicomposting with Eisenia fetida or by compost maturing. Vermicomposting did not result in significantly more intensive mineralisation than composting; the average organic carbon contents were 21.2 and 22.2% in vermicomposts and composts, respectively. Hence, the average total (N: 2.4%; P: 1.9%; K: 0.9%) and available (N: 160 mg/kg; P: 161 mg/kg; K: 0.8%) macronutrient concentrations were the same in both treatments. The processing method did not influence the organic matter quality (E4/E6) either. However, on average the concentration of the plant growth regulator kinetin was more than twice as high in vermicomposts.
Abstract
Short-day (SD) treatment is used by forest nurseries to induce growth cessation in Picea abies seedlings. SD treatment may however increase the risk of reflushing in autumn and earlier bud break the following spring. When the start of the SD treatment is early in order to control seedling height, the duration of the SD treatment should be longer in order to prevent reflushing in autumn. However, due to the amount of manual work involved in the short-day treatment, increasing the number of days is undesirable from a practical point of view. Splitting the SD treatment could be a way to achieve both early height control and at the same time avoid autumn bud break with less workload. We tested how different starting dates and durations of SD treatment influenced on morphological and phenological traits. Regardless of timing and duration of the SD treatment, height growth was reduced compared to the untreated controls. Seedlings given split SD (7+7 days interrupted with two weeks in long days) had less height growth than all other treatments. Root collar diameter growth was significantly less in control seedlings than in seedlings exposed to early (7 or 14 days) or split (7+7 days) SD treatment. There were also differences in the frequency of reflushing and bud break timing among the SD treated seedlings, dependent on duration and starting date. If the SD treatment started early, a continuous 14-day SD treatment was not sufficient to avoid high frequencies of reflushing. However, by splitting the SD treatment into two periods of 7+7 days these negative effects were largely avoided, although spring bud break occurred earlier than in the controls.
