Abstract: Successive single day transfers of pot-grown wheat to high temperature (35/30°C day/night) replicated controlled environments, from the second node detectable to the milky-ripe growth stages, provides the strongest available evidence that the fertility of wheat can be highly vulnerable to heat stress during two discrete peak periods of susceptibility: early booting [decimal growth stage (GS) 41-45] and early anthesis (GS 61-65). A double Gaussian fitted simultaneously to grain number and weight data from two contrasting elite lines (Renesansa, listed in Serbia, Ppd-D1a, Rht8; Savannah, listed in UK, Ppd-D1b, Rht-D1b) identified peak periods of main stem susceptibility centered on 3 (s.e. = 0.82) and 18 (s.e. = 0.55) days (mean daily temperature = 14.3°C) pre-GS 65 for both cultivars. Severity of effect depended on genotype, growth stage and their interaction: grain set relative to that achieved at 20/15°C dropped below 80% for Savannah at booting and Renesansa at anthesis. Savannah was relatively tolerant to heat stress at anthesis. A further experiment including 62 lines of the mapping, doubled-haploid progeny of Renesansa × Savannah found tolerance at anthesis to be associated with Ppd-D1b, Rht-D1b, and a QTL from Renesansa on chromosome 2A. None of the relevant markers were associated with tolerance during booting. Rht8 was never associated with heat stress tolerance, a lack of effect confirmed in a further experiment where Rht8 was included in a comparison of near isogenic lines in a cv. Paragon background. Some compensatory increases in mean grain weight were observed, but only when stress was applied during booting and only where Ppd-D1a was absent.

Abstract: Studies of GHG emissions from agriculture show that there are large differences in emissions from different products. In addition some foods require more land and water resources than others, which mean that in a future with food scarcity, moving from less to more sustainable food may become a necessity for there to be enough food for everyone. A changing of consumption and production from less to more sustainable food is thus both a mitigation strategy, as well as an adaptation strategy if climate change results in less available agricultural land and water resources, and more food loss due to more extreme weather conditions. Forecasting the economic consequences of climate change on agricultural production cannot be done without taking into account our future consumption patterns.  What will be produced will always to a large extent be a result of what is being demanded by consumers. This is a presentation of two ongoing projects related to this theme. One is a newly started project on factors which influence meat consumption. In a cross-country regression analysis we will estimate the importance of different factors such as income, price levels and degree of urbanization. We are particularly interested in the interlinkages between meat production and consumption at national levels. The other project looks at typical diets in England, Spain and Norway, and will estimate through a multi objective optimization process how the diets can be changed, through taxes and subsidies, towards a diet which is both more healthy and climate friendly.

Abstract: Stakeholder engagement in research projects can take a number of forms according to the scope of the project and the purpose of the interaction. L4.2. has focused on comparing different approaches to stakeholder engagement in collaborative projects. This report presents a synthesis of the experiences and lessons learnt through the stakeholder engagement activities of LiveM researchers within MACSUR, within an Italian (Oristano) case study, and within the SOLID (Sustainable, Organic and Low Input Dairying) project. An overview of these examples, and some of the lessons drawn from them, can also be found in the MACSUR paper on stakeholder engagement methods being developed by researchers from all three MACSUR themes (Koenig et al. under production). The first part of this report describes the stakeholder engagement strategy within the SOLID project. Stakeholder engagement methods are analysed through observations of activities and using semi-structured interviews with researchers and stakeholders. Two aspects of the SOLID approach are described – the stakeholder panel and the Future Dairying workshop. Transcripts of the workshop and the contribution of the stakeholder panel to the SOLID annual meeting in Helsinki are included (Appendices 1 and 2), as a contribution to the analysis of workshop outcomes being undertaken within the SOLID project. As part of a wider suite of stakeholder engagement activities, the SOLID stakeholder panel provided an example of how ongoing oversight of scientific outputs and direction by stakeholders can be effective in identifying weaknesses in approach and communication, and in suggesting relevant and effective directions for research activities. The stakeholder workshop demonstrated a useful structure for the exploration of stakeholder concerns, their view of ideal states and their solutions for reaching them. Low participation levels demonstrated the need to understand the motivations that drive stakeholders to engage in such projects, and highlighted the value of developing long-term relationships between stakeholders and researchers that allow scientific research to become an accepted part of practical problem-solving. The second part of the report describes stakeholder engagement activities carried out in the context of one of the MACSUR regional pilot studies (Oristanese case study in Sardinia, Italy). The Oristanese case study demonstrates the potentialities and constraints of participatory methodologies in relation to the different categories of stakeholder involved. It highlights the importance of creating new spaces for dialogue between farmers, researchers and policy makers in order to promote the generation of “hybrid knowledge” (Nguyen et al. 2013) for the emergence of more sustainable and longer-lasting strategies to adapt to CC. This would require the promotion of open knowledge generation platforms where multiple stakeholders are encouraged to participate and make their views heard. These approaches are designed in order to overcome the misalignment between scientists’ suggestions and policy implementation. In the third part of the report, the outcomes of a “learning event” held in Sassari (MACSUR mid-term meeting) with decision makers from different EU countries, are discussed. Finally, some reflections are presented on the importance of involving local stakeholders and decision makers in research projects, of sharing views and knowledge between scientists and stakeholders, and on the pros and cons of different methodologies at the different scales of stakeholder engagement, drawing on all three examples of practice. The research approach analysed includes two important components, which are represented by “transdisciplinarity” (to be included in the macro area of “scientific knowledge”) and “local knowledge”, as fundamental elements to fill the Science and Policy Gap.
