    System archetypes represent generic behavioural patterns – or system dynamics – in any system. The concept of archetypes is mostly applied in the context of business management and organizational life. The term archetype was first coined by Peter Senge (1990) in his seminal book ‘The Fifth Discipline’. He uses systems thinking to convert companies into learning organizations; understanding complexity and reflective conservation are some of the key competences required to address complex problems. But similar archetypes of system behaviour can be found in food systems. The use of archetypes assumes that, if the underlying systemic structure that results in specific behavioural patterns is understood, action can be taken to change the structure and thus systemic behaviour and consequently outcomes. Archetypes capture the ‘common stories’ in systems thinking; that is, dynamic phenomena that occur in diverse settings. The archetypes are used as templates for diagnosing complex problems (Kim, 2000). Below, eight archetypes are explained based on the work of Kim (2000). Based on our own expertise and the information collected during a stakeholder workshop with food systems and FNS experts, we have provided examples of these archetypes in food systems. For each archetype, a set of leverage points is identified, which can offer solutions for the problematic behaviour captured by the archetype (Nguyen and Bosch, 2013).
    Affordances of agricultural systems analysis tools : A review and framework to enhance tool design and implementation

    Bio-economic farm models - Farming systems analysis - Fuzzy cognitive mapping - Literature review - Role play and serious games - Stakeholder participation
    The increasingly complex challenges facing agricultural systems require problem-solving processes and systems analysis (SA) tools that engage multiple actors across disciplines. In this article, we employ the theory of affordances to unravel what tools may furnish users, and how those affordances contribute to a tool's usefulness in co-design and co-innovation processes. Affordance is defined as a function provided by an object through an interaction with a user. We first present a conceptual framework to assess the affordances of SA tools. This framework is then applied in a literature review of three SA tools used in agricultural systems research (fuzzy cognitive mapping, bio-economic whole-farm models, and role play and serious games). Through this exercise, we extend the SA tool design and implementation dialogue by illuminating (i) links between lower-level affordances, tool design, and heuristic functioning, and (ii) the central role of use setting and facilitation in mobilizing higher-level, productive affordances. Based on our findings, we make five propositions for how SA tool design and implementation in participatory problem-solving settings can be improved.
    Schol in de Noordzee : een biografie van de platvis en de Nederlandse visserij
    Posthumus, Roelke ; Rijnsdorp, A.D. - \ 2016
    Amsterdam/Antwerpen : Uitgeverij Atlas Contact - ISBN 9789045031231 - 272 p.
    Schol is een van de populairste vissen in Europa. Eeuwenlang is gedacht dat de voorraad in zee onuitputtelijk was, hoeveel vis we ook consumeerden. Maar niets is minder waar. Zonder strikt beheer zou de schol, evenals vele andere zeedieren, verdwijnen uit de Noordzee. Schol in de Noordzee beschrijft de wonderlijke levensloop van deze platvis - zijn geboorte, gedaanteverwisseling, leefgewoonten, voortplanting-, maar is tegelijkertijd een gedetailleerde geschiedenis van de Noordzee, de Nederlandse visserij en het visserijonderzoek. En natuurlijk komt de vraag die tegenwoordig zo belangrijk is uitgebreid aan de orde: is duurzame bevissing van schol en andere vissoorten mogelijk en zo ja, welke maatregelen moeten daarvoor genomen worden? Zonder vooringenomenheid en met verstand van zaken worden alle aspecten van een van de grootste ecologische uitdagingen van onze tijd behandeld.

    Exploring dominant land uses and their associated soil-based agroecosystems in a heterogeneous agricultural landscape in the Ecuadorian Andes
    Caulfield, M. ; Fonte, S. ; Vanek, S. ; Sherwood, S. ; Groot, J.C.J. ; Tittonell, P.A. - \ 2015
    - p. 223 - 223.
    Over the past decades more and more studies have highlighted the fact that the ecosystems of agricultural landscapes, land-uses that account for significant portions of land in Ecuador (7.38 million hectares in 2013 according to INEC), provide multiple benefits to society beyond those of food, fibre and fuel provision (Fonte et al 2012; Posthumus et al 2010). However, most studies investigating these ecosystem functions have either only been conducted at the plot level or have been focused on a single ecosystem function (Balvanera et al., 2006). The current study will therefore take a more comprehensive approach by assessing different functions of the soil-based agroecosystems within the landscape (including soil physical, chemical and biological parameters, carbon storage, biomass production and yield). Moreover, within this research an attempt to assess the trade-offs in agroecosystem functioning will be
    conducted comparing different potential future land use changes developed in a participatory manner with the community. The main research steps include 1) participatory land use and soil mapping with the community using orthophotos 2) stratified sampling of the different land uses identified in the mapping 3) participatory mapping of potential future land use changes 4) statistical analysis using ANOVA to assess differences in biodiversity and agroecosystem
    functioning 5) assessment of impact of different land use change scenarios. It is expected that by describing and exploring the current land uses and their associated agroecosystem functions in a heterogeneous agricultural landscape a more nuanced insight will be provided into the influences, challenges and constraints faced by smallholder farmers and the agroecosystems upon which they rely as well as providing for a more integrative assessment to allow for better informed land use decisions and resource management planning.

    Females of the parasitoid wasp Trichogramma turkestanica produce the putative polydeoxypropionates (2E,4E,6S,8S,10S)-4,6,8,10-tetramethyltrideca-2,4-diene and (2E,4E,6S,8S,10S)-4,6,8,10-tetramethyltrideca-2,4-dien-1-ol or their enantiomers as sex specific volatiles. The structures were assigned on the basis of GC–MS investigations using synthetic reference compounds.
