Recommendations for future development of technologies for water management
- 2021

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A challenge describes both opportunities and barriers, and an enabler provides means to manage achallenge.The framework for the deliverable is based upon identifying process facilitators (e.g.workshops) and discursive abilities/devices providing enablers that partners used in order to make senseacross organizations and professional communities (developers and users) as a means to develop anddeploy digital technologies and services.IVL lead the work and edited the deliverable. Gothenburg city (CGEA), city of Amersfoort (COA) andBarcelona waste and wastewater company (BCASA) provided experiences as stakeholder and dataprovider, through user involvement.IVL Swedish Environmental Institute, Eurecat (EUT), Talkpool (TP),Civity (CIV) provided experiences from development and implementation work (focusing on stakeholderengagement and user involvement). They all contributed to the deliverable through meetings and writingone section each. Analysing the same processes from different points of view provided interesting insightsinto the development process and implications for the coming phases of the project.The Gothenburg section expresses how insights from cooperation issues from before the project, wereturned into a well-designed collaboration process (process facilitator) between developers andusers/stakeholders. In Gothenburg, engaging with various departments within the municipality and withexternal stakeholders has been a continuing learning process for IVL (case study leader).IVL graduallypresented various opportunities within the project, both in Amersfoort and Barcelona, which has beenvery much appreciated by the stakeholders. In this way, the engagement process has also enabledstakeholders to envision a number of opportunities that the new technologies empower that can becontinued beyond SCOREwater.Moreover, due to a fruitful collaboration between developers and stakeholders, both Gothenburg andBarcelona cities now envision even more opportunities and ambitions, some of which might be realizedwithin the project, some outside.Both Amersfoort and Barcelona also analyse how insights from different organizational issues influencedtheir design of process facilitators and discursive abilities.The Amersfoort section shows the influencefrom a) the different organizational structures and motives between the municipality, the for-profitcompanies and citizen volunteers and b) the differences in work processes between their policy makersand data analysts, people that seemed to be previously unfamiliar with working together.The first issuewas addressed through finding common ground in the objectives (added value as a discursive device) andthe second through designing a common process – going from simple to more complex hypothesis.In the Barcelona case, BCASA realized a) that they needed to “translate” their needs and concepts withregard to wastewater maintenance to other Catalan partners and b) that they needed to involve andengage both workers and managers at several departments for the SCOREwater project so that theyunderstand.see and value the benefits it provide and therefore engage in and support the SCOREwaterproject. EUT, TP and CIV expressed fewer specific challenges than the case studies, using familiar andproved process facilitators and discursive devices (CRISP-DM business modelling and user stories).

Swedish Clean Air and Climate Research Programme – SCAC Final report second phase
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The SCAC-2 program was initiated to provide an extended scientific knowledge base in national and international discussions and negotiations on the development of new air pollution policies and measures. Specifically, the program was focused on four main areas where additional knowledge was needed to support further actions: air pollution and climate interactions and hemispheric transport; air pollution and human health with focus on particles from transport and domestic wood burning; ecosystem effects (and air pollution – climate interactions) of ozone and nitrogen, the latter with emphasis on national nitrogen budgets and biodiversity. Finally, integrated assessment modelling and identification of the most efficient abatement strategies was included.

The response of methane and nitrous oxide fluxes to forest change in Europe

Tidskriftsartikel (refereegranskat)abstract
- Forests in Europe are changing due to interactions between climate change, nitrogen (N) deposition and new forest management practices. The concurrent impact on the forest greenhouse gas (GHG) balance is at present difficult to predict due to a lack of knowledge on controlling factors of GHG fluxes and response to changes in these factors. To improve the mechanistic understanding of the ongoing changes, we studied the response of soil–atmosphere exchange of nitrous oxide (N2O) and methane (CH4) at twelve experimental or natural gradient forest sites, representing anticipated future forest change. The experimental manipulations, one or more per site, included N addition (4 sites), changes of climate (temperature, 1 site; precipitation, 2 sites), soil hydrology (3 sites), harvest intensity (1 site), wood ash fertilisation (1 site), pH gradient in organic soil (1 site) and afforestation of cropland (1 site). On average, N2O emissions increased by 0.06 ± 0.03 (range 0–0.3) g N2O-N m−2 yr−1 across all treatments on mineral soils, but the increase was up to 10 times higher in an acidic organic soil. Soil moisture together with mineral soil C / N ratio and pH were found to significantly influence N2O emissions across all treatments. Emissions were increased by elevated N deposition, especially in interaction with increased soil moisture. High pH reduced the formation of N2O, even under otherwise favourable soil conditions. Oxidation (uptake) of CH4 was on average reduced from 0.16 ± 0.02 to 0.04 ± 0.05 g CH4-C m−2 yr−1 by the investigated treatments. The CH4 exchange was significantly influenced by soil moisture and soil C / N ratio across all treatments, and CH4 emissions occurred only in wet or water-saturated conditions. For most of the investigated forest manipulations or natural gradients, the response of both N2O and CH4 fluxes was towards reducing the overall GHG forest sink. The most resilient forests were dry Mediterranean forests, as well as forests with high soil C / N ratio or high soil pH. Mitigation strategies may focus on (i) sustainable management of wet forest areas and forested peatlands, (ii) continuous forest cover management, (iii) reducing atmospheric N input and, thus, N availability, and (iv) improving neutralisation capacity of acid soils (e.g. wood ash application).

MAGIC library for Swedish lakes: evaluation of multiple calibrations
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Den svenska definitionen på antropogen försurning är att pH har sjunkit med 0.4 pH-enheter från förindustriell tid. pH från mitten av 1800-talet uppskattas med hjälp av den dynamiska biogeokemiska modellen MAGIC. Om det inte finns tillräckligt med bakgrundsdata för att modellera kan verktyget MAGIC-biblioteket användas ( www.ivl.se/magicbibliotek ). Sjödelen av MAGIC-biblioteket består av knappt 3000 sjöar i Sverige som har modellerats med MAGIC. Biblioteket har en matchningsrutin som letar fram den sjö i biblioteket som mest liknar den sjö man vill försurningsbedöma. Den pH-förändring som har modellerats fram för sjön i biblioteket antas då även beskriva pH-förändringen i bedömningssjön.
