- A current focus of ecosystem services (ES) implementation is on the municipal level of government where international and national legislation and policies have to be translated into practice. Given this focus, an understanding of perceptions within municipalities of the ES concept is crucial to support the implementation process. Against this background, this paper examines the perceptions of Swedish municipal stakeholders for the ES concept. A 2013 Swedish federal mandate that states that the values of ecosystem services should be considered in relevant decision-making processes, provides a timely context. Current perceptions, preconditions and awareness are explored via interviews and analyses. The results show that the views on the ecosystem services concept and its usefulness are generally very positive. Conceptual knowledge use is perceived as important as is the recognition of monetary valuation of ES. However, clarification of the distinction between implicit and explicit use of the concept by stakeholders is needed. Finally, results indicate that a deeper understanding of monetary valuation of ecosystem services by municipal staff members is connected with a more critical view on monetary valuation. It is concluded that detailed and clear definitions and guidelines are needed in order to support the process of implementing ES in municipalities.

- Transdisciplinary research and collaboration is widely acknowledged as a critical success factor for solution- oriented approaches that can tackle complex sustainability challenges, such as biodiversity loss, pollution, and climate-related hazards. In this context, city governments’ engagement in transdisciplinarity is generally seen as a key condition for societal transformation towards sustainability. However, empirical evidence is rare. This paper presents a self-assessment of a joint research project on ecosystem services and climate adaptation planning (ECOSIMP) undertaken by four universities and seven Swedish municipalities. We apply a set of design principles and guiding questions for transdisciplinary sustainability projects and, on this basis, identify key aspects for supporting university–municipality collaboration. We show that: (1) selecting the number and type of project stakeholders requires more explicit consideration of the purpose of societal actors’ participation; (2) concrete, interim benefits for participating practitioners and organisations need to be continuously discussed; (3) promoting the ‘inter’, i.e., interdisciplinary and inter-city learning, can support transdisciplinarity and, ultimately, urban sustainability and long-term change. In this context, we found that design principles for transdisciplinarity have the potential to (4) mitigate project shortcomings, even when transdisciplinarity is not an explicit aim, and (5) address differences and allow new voices to be heard. We propose additional guiding questions to address shortcomings and inspire reflexivity in transdisciplinary projects.

- Experiences of intoxication elude scientific research because of their immediate and ‘inner’ nature for the intoxicated individual. In this chapter, we show how ‘trip reports’ – reports of psychedelic intoxication – from online drug information forums and libraries allow for further understanding the experience of psychedelic intoxication from LSD, DMT and psilocybin by examining psychonauts’ (i.e., recreational psychedelic users) own understandings. Methods: The chapter draws on textual ethnography to analyze the trip rapports, approaching the reports as ‘native’ texts that allow for understanding constructions, conventions and practices of intoxication among participants in online psychonaut culture. We reviewed approximately 100 reports from three online drug information forums and libraries: Bluelight, Erowid and Shroomery. By focusing on nine of these reports, we demonstrate how they can be used to analyze psychedelic intoxication. Results: Our analysis shows how psychonauts construct their experiences by combining the context of psychedelic intoxication with inner aspects. The context refers to psychosocial factors of the psychonaut, such as expectations, and their material and social surroundings, such as interior design and other people present during intoxication. The inner experience refers to the arguably psychologically internal reactions and experiences of intoxicating effects, and how the psychonauts narrate them. Conclusions: Our findings show that intoxication follows observable patterns which may best be unraveled by approaching it as structured experience. Yet, the structure of these experiences is not necessarily framed in mystic or religious ways, suggesting that trip reports may complement current research on psychedelic intoxication that approaches it as religious or mystic experiences. Moreover, we suggest that further research should examine the systematics of context and inner experience of psychedelic intoxication which might aide the development of better methods for harm reduction and the study of the therapeutic potential of psychedelics.

Modelling Daily Gross Primary Productivity with Sentinel-2 Data in the Nordic Region-Comparison with Data from MODIS
- 2021

Tidskriftsartikel (refereegranskat)abstract
- The high-resolution Sentinel-2 data potentially enable the estimation of gross primary productivity (GPP) at finer spatial resolution by better capturing the spatial variation in a heterogeneous landscapes. This study investigates the potential of 10 m resolution reflectance from the Sentinel-2 Multispectral Instrument to improve the accuracy of GPP estimation across Nordic vegetation types, compared with the 250 m and 500 m resolution reflectance from the Moderate Resolution Imaging Spectroradiometer (MODIS). We applied linear regression models with inputs of two-band enhanced vegetation index (EVI2) derived from Sentinel-2 and MODIS reflectance, respectively, together with various environmental drivers to estimate daily GPP at eight Nordic eddy covariance (EC) flux tower sites. Compared with the GPP from EC measurements, the accuracies of modelled GPP were generally high (R-2 = 0.84 for Sentinel-2; R-2 = 0.83 for MODIS), and the differences between Sentinel-2 and MODIS were minimal. This demonstrates the general consistency in GPP estimates based on the two satellite sensor systems at the Nordic regional scale. On the other hand, the model accuracy did not improve by using the higher spatial-resolution Sentinel-2 data. More analyses of different model formulations, more tests of remotely sensed indices and biophysical parameters, and analyses across a wider range of geographical locations and times will be required to achieve improved GPP estimations from Sentinel-2 satellite data.

Public-private sector partnership in household waste management as perceived by residents in south-west Nigeria
- 2012

- In most developing countries public-private sector partnership is becoming increasingly applied in household waste management service delivery especially in urban areas to reduce cost and improve effectiveness. This paper reports a study of householders' perceptions of public-private sector partnership in provision of household waste management services in Ilorin, south-west Nigeria. A multistage random sampling technique was used to select 224 households for the study. The data generated from the survey were analysed using a binary logit model. The results show that most of the respondents were of the opinion that the public-private partnership has not been able to improve household waste management services. Time taken to visit solid waste collection point, income and marital status negatively influenced their perceptions, while activities of sanitary inspectors, occupation and gender had positive influence. The public-private partnership will be more effective and sustainable if the public sector could pay more attention to performance monitoring and accountability.

Biodigestion of Plant material Can Improve Nitrogen Use Efficiency in a Red Beet Crop Sequence
- 2011
-
Ingår i: Hortscience. - : American Society for Horticultural Sciences. - 0018-5345 .- 2327-9834. ; 46:5, s. 765-775

Tidskriftsartikel (refereegranskat)abstract
- Nitrogen (N) tied up in or lost from decomposing biomass decreases the residual N effects of green manure and of other crop residues. During anaerobic degradation in a biogas digestor (biodigestion), N mineralization takes place under conditions in which losses can be kept to a minimum. Therefore, biodigestion of green manure biomass and beet foliage was tested to generate readily available N and compared with a direct green manure fertilization system. The effluent was applied as fertilizer in field experiments on a sandy soil as a tool for improving N supply for an organic farming system. Data from the field experiments were used for simulating the amount of net inorganic N equivalents (inorganic N equivalents from effluent plus inorganic N equivalents from pre-crops) in three crop sequences: A) green manure ley, red beets, winter rye; B) harvested ley, red beets, winter rye; and C) harvested ley, spring barley, red beets in which (B) and (C) represented biogas nutrient management systems and (A) a green manure system. When all available effluent from biogas production from 1 ha of grass–clover ley with two or three harvests (2H-ley or 3H-ley) and one hectare of beet foliage was used as a fertilizer for red beets (Beta vulgaris var. conditiva Alef) after barley (Hordeum vulgare L.), the yield of marketable red beets increased by 5.7 Mg·ha–1 (33%) with effluent from 2H-ley and beet foliage and 9.1 Mg·ha–1 (53%) with effluent from 3H-ley and beet foliage compared with red beets grown without effluent fertilization after a green manure ley. When total dry matter production was taken into account, the advantage for the BG systems with 2H- and 3H-ley was 15% and 28%, respectively. The nitrate concentration in the red beets was not higher with effluent supplied at this level than with green manure as the only N source. The simulated amount of net inorganic N equivalents was 128 kg N for the whole of crop sequence (C) with 1 ha of each crop and where effluent supply to red beets was based on digested biomass in ley and beet tops. The corresponding amount of net inorganic N equivalents for the green manure crop sequence (A), in which no effluent was supplied, was 73 kg N. Unused soil mineral N (0- to 90-cm depth) at red beet harvest indicated that the risk of leaching in BG systems was lower than in GrM systems (88, 76, and 61 kg Nmin/ha left after unmanured beets after Gr-M-ley, low manured beets after 3H-ley and high manured beets after barley, respectively). Effluent fertilization of red beets directly after 2H- and 3H-ley gave unexpectedly low yield responses compared with red beets after barley. The reasons may be the result of nutritional imbalance of other nutrients than N or may be plant pathological in nature. The conclusion is that a nutrient management system with biodigestion can increase net inorganic N equivalents and reduce risk for N leaching, but inappropriate use of the effluent, i.e., at an unsuitable point in the crop rotation, may negate the benefits.

A decade of maize yield gap studies in sub-Saharan Africa : how are farm-level factors considered?
- 2024
-
Ingår i: International Journal of Agricultural Sustainability. - : Routledge. - 1473-5903 .- 1747-762X. ; 22:1

Tidskriftsartikel (refereegranskat)abstract
- The study of yield gaps has become more complex, prompting the use of varied approaches to measure yields and a wider range of factors to explain these gaps. In the Global North, the focus is on precision farming, whereas in sub-Saharan Africa (SSA), a broader perspective is necessary due to pronounced variability in farmland conditions. While biogeophysical and management factors have been traditional focal points in yield gap analyses, socio-economic and institutional factors are increasingly recognized as significant, especially in SSA. This review synthesizes research from the past decade in SSA that integrates biogeophysical, management, farm characteristics, and institutional factors in yield gap discussions. The findings indicate a slow shift in including socio-economic factors, with management, particularly nutrient supply and crop management, remaining predominant. However, there is a growing trend towards methodological diversity, such as the adoption of remote sensing and GIS in recent years. Case studies from Kenya and Ghana, utilizing field surveys, interviews, panel data, and spatial analysis, highlight how a multifaceted approach can enhance our understanding of the various elements influencing maize yield gaps in SSA.

Konferensbidrag (refereegranskat)abstract
- Today, there is a common understanding that universities and the stakeholders in the society need to collaborate in order to handle big societal challenges. Sometimes this is mention as a need of developing mode 2-knowledge. Other times it is describe as a need of developing triple helix processes. A general problem for these kinds of collaborations is different needs of knowledge and different conditions for knowledge production. University knowledge are mainly general and focal, are disseminated mainly through text. Knowledge among stakeholders outside the university, like citizens or professionals, is situated and tacit, and is mainly disseminate through practice. The aim with the paper is two-fold. First, we would like to describe a model for knowledge development between urban researchers and professional public planners. The model was developed by a group of urban planners together with the authors of the paper, who were engaged as on-going evaluators of an urban regeneration project. The aim with the model was to summarize their personal experience of working with collaborative urban planning. The model could therefore be seen as a way for those urban planners to conceptualize their personal experience of an urban developmental project, with the help of urban researchers. During the work with the model, we need to handle the tension between theoretical knowledge versus tacit personal knowledge. How could we as researcher support the transformation of tacit knowledge into a more general model based on focal knowledge? Based on this experience, we take a step back in the second part of the paper, and try to understand the process which leads to the development of the model. Here we will use this process as a way to illustrate what we see as the main challenge in university – society interaction: different needs of knowledge, and different ways to develop knowledge. We will argue that collaboration between university and the society, irrespective of which stakeholders is included in the collaboration, must handle the tensions between different conditions for knowledge production within the academia and outside it. Our way of working is one way to this.
