Viljavuusfosforin muutokset Rehtijärven valuma-alueella

Rehtijärvi on ainoa kokonaan Jokioisten kunnan alueella sijaitseva järvi. Sen pinta-ala on noin 40 hehtaaria ja kokoisekseen järveksi se on poikkeuksellisen syvä. Järven rajoittuminen harjualueeseen tekee siitä merkittävän raakaveden lähteen, sillä suuri osa harjusta saatavasta pohjavedestä imeytyy Rehtijärvestä. Järvi on tärkeä myös kunnan virkistyskäyttöä ajatellen. Rehtijärvessä on jo pitemmän aikaa esiintynyt sinilevää lähes vuosittain. Vuonna 1994 aloitettiin järven kuormituksen seuranta.vo

Time and Mobility after the Anthropocene

The Special Issue on ‘After the Anthropocene: Time and Mobility’ is published. It discusses the geological time to follow the human-dominated epoch and ways to move there. In addition to this editorial, a total of five articles are published in the issue. The articles engage with a variety of social science disciplines—ranging from economics and sociology to philosophy and political science—and connect to the natural science insights on the Anthropocene. The issue calls for going beyond anthropocentrism in sustainability theory and practice in order to exit the Anthropocene with applications and insights in the contexts of politics (Ruuska et al., 2020), energy (Mohorčich, 2020), tourism (Rantala et al., 2020), food (Mazac and Tuomisto, 2020) and management (Küpers, 2020). We hope that you will find this Special Issue interesting and helpful in contributing to sustainable change

Järvien ruoppausmassat kierrätetään pelloille

Ruoppaus eli sedimentin poisto on usein ainoa keino, jos vesialue halutaan säilyttää järvenä. Suomessa on runsaasti liian matalia tai umpeenkasvavia järviä, joiden valuma-alueiden pelloilla on liian vähän humusta. Ruoppausmassat voidaan hyödyntää maataloudessa ja samalla valuma-alueelta järveen kulkeutunut kiintoaines ja ravinteet palautuvat takaisin käyttöönvo

Made-to-Measure: In and Out of Touch with the Old-Growth Forest

The condition of forests is a major issue when it comes to climate change and biodiversity. One way to define the quality of a forest is by its age. In the cross pressure of socio-economic and ecological guidelines, what qualifies as an old-growth forest is not determined by a mere number but the co-constitution of various measurements, indicators, political ambitions, and the performance of the measured biological ‘units’ themselves. This transdisciplinary chapter studies how old-growth forests are made-to-measure, moving from close proximity encounters with an indicator organism, being-with-beard lichen, to the internationally defined level and timescale of economic activity and (un)management in categorising forest ecology, wherein various compromises in decision-making may also compromise local ecosystems and the vastness of scale in the biosphere. The study heads off to the ‘roots’ of science—definitions, conceptualisations, onto-epistemology, and methodologies—considering how they as active processes are performing the entity of the ‘old-growth forest’ by cutting-together-apart on multiple scales

Data in sustainable production chain management

The aim of this paper is to innovate the role of data in sustainable production chain management by identifying drivers, challenges and future solutions related to sustainability and data utilisation. The research data was collected from a literature review, a sustainability seminar entitled “Strong Stronger Responsible” and interviews with company representatives. The interviewees represented operators in the renewable forest and chemical industries and the companies serving them. This study examines sustainability data on the wood fibre-based production chain, from the forest to the consumer. The results show that for sustainability data, production chains have challenges and development needs in terms of indicators, data collection, quality and sharing. Sustainability data should guide decision making in processes at all levels of the organisation, as well as in the production chain

Two sides of biogas : Review of ten dichotomous argumentation lines of sustainable energy systems

Societal debates are often constructed through dichotomies influenced by various factors such as cognitive capabilities of individuals, culturally shaped valuation processes, underlying societal struggles for power and prestige, economic competition, technological changes or lock-ins and operation logic of the media and social media. Debates over emerging technologies of renewable energy provide an illustrative example of this polarisation. Based on national-level studies focusing on the development of the biogas sector in Finland, we identify ten pertinent dichotomies of renewable energy and discuss their implications for the transition towards a more sustainable energy system. The dichotomies include: producer vs. consumer, urban vs. rural, local vs. national, domestic vs. foreign, centralised vs. distributed, food vs. energy, environment vs. economy, traditional vs. innovative, long-term vs. short-term, and private vs. public. These diverse and deeply rooted dichotomies structure societal debate. In some cases they may encourage and guide critical thinking, but they may also hinder the renewing of the current energy behaviour and energy system. Societal capabilities that enable the bridging of different but inherently linked dichotomies are a key precondition of sustainable energy transition.peerReviewe
