Therefore, the aim of this study is to analyse consumers’ perspective on dual‐purpose chickens. To get an insight into consumers’ perspective, we initially conducted six focus groups with German consumers focussing on their chicken meat and egg preferences, perception of chicken farming and attitudes towards dual‐purpose chicken breeds. The results show that most of the participants were aware of the killing of day‐old chicks. However, alternatives were scarcely known. After giving the participants information about dual‐purpose chickens, they were generally in favour of this chicken breed. Some participants raised concerns regarding the economic efficiency and the higher product prices. For others, ethical values predominated. All in all, the results demonstrate that the discussants have specific expectations regarding the husbandry conditions but also regarding the product characteristics and the labelling of dual‐purpose chickens.","PeriodicalId":37887,"journal":{"name":"International Journal on Food System Dynamics","volume":"9 1","pages":"390-398"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48452518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the project is to analyze the dynamics of food supply- and value chain systems using a structural analysis including system analysis and perform system simulations using system dynamics. The VALUMICS research approach and the project design are explained and it is justified why system analysis is needed to obtain an understanding of the complex connections and interactions of the distinct parts of food systems. Patterns will be recognized and thus causes and effects of complex relations within the selected food supply system and networks will be identified. This understanding of the functioning of the system can in turn be used to identify policy interventions.","PeriodicalId":37887,"journal":{"name":"International Journal on Food System Dynamics","volume":"1 1","pages":"409-418"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41243195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To minimize the losses due to climate change factors, farmers have employed different climate change adaptation strategies. Consequently, this study examines farmer adaptation strategies to climate change in Benishangul-Gumuz Regional State of Ethiopia based on a cross-section data of three representative zones of Assosa, Kamashi zones and Mao-komo special district. The study describes the perceptions of smallholder farmers to changes in climate change indicators and adaptation measures at the farm household level using multivariate discrete choice model to identify the determinants of adaptation strategies. The econometric model has showed that households demographic factors, resources endowments (land, labor, livestock), institutional factors (access to extension services, cooperative membership and access to credit) are some of the important determinants of farm-level adaptation. The policy implication from our finding is that improving access to credit, production factors (like land, labor) enhancing the bargaining power of smallholder farmers can significantly increase farm-level adaptation to climate change. Moreover, adopting different improved crop varieties have showed better yield gains than non-adopters. Thus, policies and strategies should focus at research and development on appropriate technologies that help smallholder farmers’ adaptation capacity to climate changes hereby varietal development, appropriate agronomic recommendations, pre-extension demonstration and popularization of improved cultivars and promoting appropriate farm-level adaptation measures such as use of irrigation technologies.","PeriodicalId":37887,"journal":{"name":"International Journal on Food System Dynamics","volume":"9 1","pages":"453-469"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41440467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sustainable intensification relates not just to primary production, but also has wider value chain implications. An input-output model is a modelling framework which contains the flows across a value chain within a country. Input-output (IO) models have been disaggregated to have finer granular detail in relation to agricultural sub-sectoral value chains. National IO models with limited agricultural disaggregation have been developed to look at carbon footprints and within agriculture to look at the carbon footprint of specific value chains. In this paper we adapt an agriculturally disaggregated IO model to analyse the source of emissions in different components of agri-food value chains. We focus on Ireland, where emissions from agriculture comprise nearly 30% of national emissions and where there has been a major expansion and transformation in agriculture since the abolition of milk quota restrictions. In a substantial Annex to this paper, we describe the modelling assumptions made in developing this model. Breaking up the value chain into components, we find that most value is generated at the processing stage of the value chain, with greater processing value in more sophisticated value chains such as dairy processing. On the other hand, emissions are in general highest in primary production, albeit emissions from purchased animal feed being higher for poultry than for other value chains, given the lower direct emissions from poultry than from ruminants or sheep. The analysis highlights that emissions per unit of output are much higher for beef and sheep meat value chains than for pig and poultry meat value chains.","PeriodicalId":37887,"journal":{"name":"International Journal on Food System Dynamics","volume":"10 1","pages":"55-85"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41485004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumers’ identification with cross‐cultural human values is measured according to the Schwartz’ Portrait Values Questionnaire; the distribution of preferences for product attributes that claim a positive social impact among respondents with different human values is modeled using mixed logit analysis. Parallel survey studies were conducted in each country with the intention of comparing the impact of human values using the Schwartz Values framework on willingness to pay for early potatoes with several credence process attributes that may signal a positive social outcome as a result of purchase (price, country of origin, carbon footprint certification, ethical certification, and method of production). This paper aims to help clarify the role, if any, that pro‐social consumer values have in influencing the willingness to pay for specific food credence process attributes that claim to have a social impact. To the best of our knowledge this is one of the first paper to focus on the role human values have in influencing the willingness to pay for specific extrinsic food attributes.","PeriodicalId":37887,"journal":{"name":"International Journal on Food System Dynamics","volume":"59 13","pages":"354-374"},"PeriodicalIF":0.0,"publicationDate":"2018-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41285408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
