    This report explores first of all literature on transition management. The knowledge gained is taken into account to develop a route planner, which can be used to stimulate nature-inclusive agriculture at a regional level. This route planner is intended for stakeholders who want to promote nature-inclusive agriculture in their own region. We then ask ourselves what nature-inclusive agriculture means, and how it relates to circular agriculture and ecosystem services. An important focus in the route planner is the development of a vision. For this reason, concrete measures are described for arable farming and livestock farming that fit into such a nature-inclusive vision.
    Bodemmaatregelen op dalgrond in de Veenkoloniën: effecten op bodemkwaliteit, opbrengst en financiële meerwaarde : Analyse van de resultaten van de systeemproef Bodemkwaliteit Veenkoloniën 2014-2017

    In een langjarig experiment op proefbedrijf Valthermond wordt op dalgrond met gemiddeld 11% organische stof een vijftal maatregelen in een vierjarige akkerbouwvruchtwisseling vergeleken met de standaard werkwijze, in vier herhalingen. De maatregelen Tagetes, Compost, sturen Ca/Mg-verhouding, Steenmeel zijn elk op hun eigen wijze gericht op verbetering van de bodemkwaliteit. Ook een combinatie van alle maatregelen is onderzocht. Over de maatregelen heen liggen varianten van grondbewerking (NKG en Spitten) in duplo. Na vier jaar blijkt de maatregel Tagetes (de teelt van zomergerst vervangen door een hoofdteelt Tagetes) zowel meer opbrengst op te leveren in de aardappelteelt als economisch rendabel te zijn, ondanks de opbrengstderving door het wegvallen van de verkoop van gerst. De andere strategieën hebben weinig of geen effect op de opbrengst en de kosten zijn hoger dan de eventuele extra inkomsten door opbrengstverhoging. NKG lijkt een positief effect te hebben op de opbrengst maar dat is nog niet statistisch significant. Wel leidt NKG tot kostenbesparing ten opzichte van Spitten door lagere machinekosten en lager brandstofverbruik. Veranderingen in bodemkwaliteit zijn nog nauwelijks waargenomen. Dat komt naar verwachting mede doordat die effecten meer tijd nodig hebben om zich te tonen. De nitraatnorm voor grondwater wordt meestal overschreden, onafhankelijk van de maatregel. Waar de norm wel gehaald wordt ligt het aan bodem en grondwater, niet aan de bemestingsstrategie. Het onderzoek wordt voortgezet.

    climate services - ice and climate (WWIC) information - information needs - mobile sectors - mobilities - Polar Regions - water - Weather

    The Polar Regions are undergoing rapid environmental change while simultaneously witnessing growth and diversification of human activity. These changes call for more responsive, detailed and specialized weather, water, ice and climate (WWIC) information services so that the risks related to human activities can be minimized. Drawn from an extensive literature review this article provides an examination of selected sectors and their uses of WWIC information services in order to offer an initial understanding of diverse environmental forecasting needs. Utilizing a mobilities perspective we provide a characterization of mobility in the Polar Regions to help contextualize current WWIC uses and needs. Using four illustrative case studies of polar mobilities (community activities; cruise tourism; shipping; and government and research operations) the article explores two broad questions: (1) How are mobilities characterized in the Polar Regions? (2) What is known about the role of WWIC information in Polar mobilities? The findings suggest an incongruence between the information provided and the ways in which WWIC information is both used and needed by various sectors. Knowledge gaps are outlined that suggest more efforts are needed to understand the highly complex set of interconnections between WWIC users, providers, mobilities and decision-making across the Polar Regions.

    climate services - ice and climate (WWIC) information - information providers - Polar Regions - water - Weather

    Environmental conditions in Polar Regions are becoming more dynamic due to climate change. As sea ice melts, the range of human activities in Polar Regions are projected to increase, while weather conditions are becoming more extreme and unpredictable. Provision and use of weather, water, ice and climate (WWIC) information plays a key role in ensuring that polar activities are conducted as safely as possible and can contribute to a reduction of the environmental footprint of human activities. In this article, we explore the WWIC information provider landscape in a polar context, drawing on a database we compiled to characterize the diversity of providers. The database is built on available literature and on an extensive desk-based research of WWIC information provider websites. We analyse the 374 providers categorized by (a) institutional background (public vs private), (b) the position of the provider relative to activities in the WWIC information space, and (c) the users they serve. While governmental institutions have a strong presence in information provision, new types of providers are now entering the scene. Scientific actors seem to play a substantial role as users as well as major providers of WWIC information services.

    abundance - dissimilarity - forest - functional traits - global - plant invasion - trees

    Aim: Alien plant species can cause severe ecological and economic problems, and therefore attract a lot of research interest in biogeography and related fields. To identify potential future invasive species, we need to better understand the mechanisms underlying the abundances of invasive tree species in their new ranges, and whether these mechanisms differ between their native and alien ranges. Here, we test two hypotheses: that greater relative abundance is promoted by (a) functional difference from locally co-occurring trees, and (b) higher values than locally co-occurring trees for traits linked to competitive ability. Location: Global. Time period: Recent. Major taxa studied: Trees. Methods: We combined three global plant databases: sPlot vegetation-plot database, TRY plant trait database and Global Naturalized Alien Flora (GloNAF) database. We used a hierarchical Bayesian linear regression model to assess the factors associated with variation in local abundance, and how these relationships vary between native and alien ranges and depend on species’ traits. Results: In both ranges, species reach highest abundance if they are functionally similar to co-occurring species, yet are taller and have higher seed mass and wood density than co-occurring species. Main conclusions: Our results suggest that light limitation leads to strong environmental and biotic filtering, and that it is advantageous to be taller and have denser wood. The striking similarities in abundance between native and alien ranges imply that information from tree species’ native ranges can be used to predict in which habitats introduced species may become dominant.

    Kosten en baten van bodemmaatregelen : Grondbewerking, organische stofaanvoer en Tagetes patula als aaltjesvanggewas

    Bodemstructuur, organische stof en bodemgezondheid zijn belangrijke aandachtspunten in de akkerbouw. In langjarige systeemproeven op verschillende grondsoorten is onderzoek gedaan naar verschillende grondbewerkingsmethoden, organische stofstrategieën en aaltjesvanggewassen. In deze kosten-batenanalyse zijn de resultaten van de proeven geëvalueerd. De onderzochte maatregelen laten economisch vaak relatief kleine verschillen zien met de referentie. In een aantal gevallen is er wel een groter verschil, vooral als de opbrengst van hoogsalderende gewassen door de maatregel verandert. Dat is soms positief (hogere lelie-opbrengst door Tagetes patula als aaltjesvanggewas), soms negatief (lagere peen-opbrengst door NKG op klei).

    adaptation - barley - common garden trials - exome sequence haplotypes - genetic diversity - genotype-by-environment interactions - H. vulgare ssp. vulgare

    Broadening the genetic base of crops is crucial for developing varieties to respond to global agricultural challenges such as climate change. Here, we analysed a diverse panel of 371 domesticated lines of the model crop barley to explore the genetics of crop adaptation. We first collected exome sequence data and phenotypes of key life history traits from contrasting multi-environment common garden trials. Then we applied refined statistical methods, including some based on exomic haplotype states, for genotype-by-environment (G×E) modelling. Sub-populations defined from exomic profiles were coincident with barley's biology, geography and history, and explained a high proportion of trial phenotypic variance. Clear G×E interactions indicated adaptation profiles that varied for landraces and cultivars. Exploration of circadian clock-related genes, associated with the environmentally adaptive days to heading trait (crucial for the crop's spread from the Fertile Crescent), illustrated complexities in G×E effect directions, and the importance of latitudinally based genic context in the expression of large-effect alleles. Our analysis supports a gene-level scientific understanding of crop adaption and leads to practical opportunities for crop improvement, allowing the prioritisation of genomic regions and particular sets of lines for breeding efforts seeking to cope with climate change and other stresses.

    Essential environmental resources are rapidly exploited globally, while social-ecological systems at different scales fail to meet sustainable development challenges. Ecosystem services research, which at present predominantly utilizes static modelling approaches, needs better integration with socio-economic dynamics in order to assist a scientific approach to sustainability. This article focuses on Brownfield lands, a unique landscape that is undergoing transformations and provides ecosystem services that remain, at this point in time, mostly unrecognized in public discourse. We discuss the main issues associated with current modelling and valuation approaches and formulate an ecosystem-based integrated redevelopment workflow applied to the assessment of Brownfield redevelopment options.

    Nanoparticle in vitro toxicity studies often report contradictory results with one main reason being insufficient material characterization. In particular the characterization of nanoparticles in biological media remains challenging. Our aim was to provide robust protocols for two of the most commonly applied techniques for particle sizing, i.e. dynamic light scattering (DLS) and differential centrifugal sedimentation (DCS) that should be readily applicable also for users not specialized in nanoparticle physico-chemical characterization. A large number of participants (40, although not all participated in all rounds) were recruited for a series of inter-laboratory comparison (ILC) studies covering many different instrument types, commercial and custom-built, as another possible source of variation. ILCs were organized in a consecutive manner starting with dispersions in water employing well-characterized near-spherical silica nanoparticles (nominal 19 nm and 100 nm diameter) and two types of functionalized spherical polystyrene nanoparticles (nominal 50 nm diameter). At first each laboratory used their in-house established procedures. In particular for the 19 nm silica particles, the reproducibility of the methods was unacceptably high (reported results were between 10 nm and 50 nm). When comparing the results of the first ILC round it was observed that the DCS methods performed significantly worse than the DLS methods, thus emphasizing the need for standard operating procedures (SOPs). SOPs have been developed by four expert laboratories but were tested for robustness by a larger number of independent users in a second ILC (11 for DLS and 4 for DCS). In a similar approach another SOP for complex biological fluids, i.e. cell culture medium containing serum was developed, again confirmed via an ILC with 8 participating laboratories. Our study confirms that well-established and fit-for-purpose SOPs are indispensable for obtaining reliable and comparable particle size data. Our results also show that these SOPs must be optimized with respect to the intended measurement system (e.g. particle size technique, type of dispersant) and that they must be sufficiently detailed (e.g. avoiding ambiguity regarding measurand definition, etc.). SOPs may be developed by a small number of expert laboratories but for their widespread applicability they need to be verified by a larger number of laboratories.
    Triggering regime change: A comparative analysis of the performance of innovation platforms that attempted to change the institutional context for nine agricultural domains in West Africa
    Hounkonnou, Dominique ; Brouwers, Jan ; Huis, Arnold Van; Jiggins, Janice ; Kossou, Dansou ; Röling, N.G. ; Sakyi-dawson, Owuraku ; Traoré, Mamoudou - \ 2018

    The article synthesises the experiences of innovation platforms (IPs) that engaged in open-ended experimental action to improve the institutional context for smallholder farm development in West Africa. The IPs sought change at the level of the institutional regime covering an entire agricultural domain (such as cocoa, cotton, oil palm or water management). Their purpose was therefore not to ‘roll out’ farm-level technologies across rural communities. The IPs's outcomes were documented and analysed throughout by means of theory-based process tracing in each of seven of the nine domains in which regime change was attempted. The evidence shows that by means of exploratory scoping and diagnosis, socio-technical and institutional experimentation, and guided facilitation IPs can remove, by-pass, or modify domain-specific institutional constraints and/or create new institutional conditions that allow smallholders to capture opportunity. The article describes the 5-year, €4.5 million research programme in Benin, Ghana and Mali, covering theory, design, methods and results. It is the sequel to Hounkonnou et al. in AGSY 108 (2012): 74–83.
