In this work, we aimed to uncover these facets of value. To do so, we built upon two conceptual models: a Triple Layered Business Model Canvas and an eight-dimensional blueprint developed for our purposes. Then, we conducted two studies using these models as theoretical templates. In Study I, we followed a business model canvas perspective, aiming to portray the components that contribute to the generation of economic, functional, and social value produced in SFSCs. By drawing on a sample of farmers who participate in SFSCs, we developed regression models to uncover the antecedents of value. Our analysis revealed that the effectiveness of performed activities catalyses the economic value of SFSCs. In addition, the social value depends on the capacity of SFSCs to enhance local communities’ well-being and provide significant outreach. Finally, environmental value is associated with the distribution of products. In Study II, using data from a pool of experts, we assessed the importance of eight facets of value. Participants appraised economic, social, cultural, and environmental value as more important than the remaining dimensions. Our studies shed light on the dimensions of value created in SFSCs, also confirming the usefulness of business model canvases for understanding value creation processes. However, our work also offers a new framework for conceptualising supply chains’ value, distinguishing value into primary (which is produced and remains within SFSCs) and secondary (which extends beyond supply chain limits).","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114331437","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}

However, it is difficult to create a dedicated food chain and to develop a business model in the North Sea countries. This study aims to explore whether islands can be an incubator for saline agriculture by looking at a saline agriculture initiative on Terschelling, the Netherlands, which focusses on the touristic niche market. We conducted semi-structured interviews to map the value chain on the island and identify opportunities and constraints for its development. Drawing on the innovation theory, we analyse to what extent small islands can be considered a favourable niche for sustainability innovations such as saline agriculture. Our results confirm the potential for production and marketing of local saline food specialities on Terschelling, although the market and value chain still require further development. The potential of this initiative is considered positive, although at this stage external support is needed in the form of voluntary labour or subsidies. We conclude that islands are a favourable niche for the introduction saline agriculture as such island initiatives can be a stepping stone for a wider introduction of saline agriculture as a climate adaptive strategy.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114593457","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 study described the indigenous cattle reproductive performances, management practices and production limitations in north-western Ethiopia. Multistage purposive and random sampling methods were used to select the study sites/districts and households. A semi-structured questionnaire (320 interviewees), focus group discussions (12) and personal observations were used for data collection. Chi-square (χ2) test, the least squares mean and the ranking indexes were the statistical methods employed for data analysis. Livestock composition, reproductive performance and production constraints of cattle showed significant differences (p < 0.001) between agro-ecological zones. Cattle were the dominant livestock species, with mean numbers of 18.3 ± 9.9, 8.1 ± 3.2 and 5.4 ± 2.5 heads in the lowland, midland and highland agro-ecological zones, respectively. The mean ages at first mating of bulls, first service of heifers, first calving and calving interval of cows were best in the highlands, while the midland agro-ecology had the worst performance. Feed shortage (Index = 0.4) and disease prevalence (Index = 0.25) were the main cattle production problems. Natural pasture was the main feed source for cattle in the study areas. The study revealed a significant effect agro-ecology on landholding, cattle management practices, species composition; cattle herd structure, reproductive performances and cattle production constraints. This implies that the socioeconomic characteristics, management-level constraints for production and performance level of the livestock stock are important for developing improvement strategies for smallholder livestock production in different agro-ecological zones.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124624419","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}

We considered four case studies of ethnic communities that are divided by political borders. In total, we conducted 581 semi-structured interviews. Our results suggest three main findings. The first regards the high similarity of use of wild food plants among the communities living in Russia and Finland. The second involves the higher proportion of simple preparations made with wild food plants in Soviet contexts, which is not evident in adjacent non-Soviet countries. The third concerns the low(er) number of distinct wild plant-based foods retained by non-Soviet countries and, in post-Soviet contexts, those that refer to past uses. We argue that the erosion of wild food plant-based local gastronomic knowledge guided by homogenization and repression poses a serious risk to local food security.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132049721","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}

We developed our conceptual framework of the “cross-border innovation environment” based on innovation system and innovation management literature. We conducted semi-structured interviews in selected agri-food enterprises in the Dutch-German region Rhine-Waal. Results indicate that agri-food enterprises’ innovation environments concentrated on national-level factors, and that cross-border factors and relationships were rare. Moreover, different factors influenced different stages of innovation processes that were primarily driven by markets compared to research. We conclude that integrating customers and business partners during research and technological development is important to address current challenges of the Green Deal. Understanding how the innovation environment influences innovation processes in agri-food enterprises can help to develop appropriate policies.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115344160","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}

Despite being a public good, food safety in these economies is often addressed through limited private sector innovations while the public health costs and impact of food-borne diseases are largely unknown. This study estimates annual private and public costs and benefits of a quality-based milk payment system (QBMPS) in Kenya. Private costs and benefits were estimated using a partial budget analysis. From a private perspective, results show that participating farmers benefit most from the QBMPS, with a net profit of about USD 0.02 USD/kg) from an additional investment cost USD 0.0125/kg to produce Grade A milk. The cooperatives and processor have a net loss of 0.025 USD/kg milk, mainly driven by testing and initial investment costs. Disease burden was calculated using the Disability Adjusted Life Years (DALYs), while direct and indirect health costs were calculated using an incidence-based analysis. We estimate an annual disease burden of 53,000 DALYs from milk-related infectious diseases and a generated health benefit of 13 KES/kg due to reduction in disease incidence if 15% of Kenya’s milk goes through the QBMPS. These health benefits justify public and private sector support for a QBMPS.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132967292","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}

Since its emergence, stakeholders implement – with limited success – isolated efforts to reduce the spread of this problem. Hence, this study aimed to derive stakeholders’ enabling responses to manage the spread of emerging plant diseases and pests, and to analyse the spread of purple top in Ecuador together with the responses of the stakeholders. We review 108 articles on human, animal, and plant epidemics to derive enabling responses to manage the spread of emergent diseases and pests. Then, we describe the spread of purple top and stakeholders’ responses using an innovation history analysis approach. Our results show that managing epidemics calls for collaboration and coordination, communication and raising awareness, design and implementation of interventions, funding, supporting regulations and policies, research, and surveillance. We show that the complexity of the diagnosis of causal agent(s) of purple top caused uncertainty among stakeholders. Each actor experienced the purple top’s epidemic differently depending on her or his role. Poor coordination between scientists and other stakeholders, and lack of political lobby hindered the diagnosis and development of management strategies for purple top. A delayed identification, due to the complexity of the causal agent and poor coordination, can further hinder the mobilisation of necessary resources. Our results together indicate that managing epidemics requires more than identifying the causal agent(s) and vectors. We expect that the findings of this study are useful to improve preparedness for other plant disease epidemics affecting food security crops.","PeriodicalId":211218,"journal":{"name":"NJAS: Impact in Agricultural and Life Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115013138","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}
