Distinguishing between ‘Normal’ and ‘Extreme’ Price Volatility in Food Security Assessment
Get PDFVolatile food prices are held to threaten food security worldwide, but controversy over how to distinguish between ‘normal’ and ‘extreme’ volatility compromises threat assessment and identification of countermeasures. Whether food-market dynamics normally stabilize or destabilize prices is the source of controversy. The conventional view is that market dynamics are inherently stable so that price volatility—arising from exogenous shocks normally stabilizes due to forces of supply and demand. Extended food panics are improbable, reducing need for interventionist public policy. An emergent alternative view is that market dynamics are inherently unstable so that volatility persists endogenously. Interventionist public policy is needed to deal with chronic food panics
Adapting Supply Chain Management for Local Foods Logistics
Get PDFSupply chain management is adapted to the particularities of local foods production characterised by short chains and intensive horizontal and vertical networking in an integrated context. A case study of chain of local foods logistics to a common retailer in Norway empirically grounds what constitutes "supply chain management of local foods". Findings based on analysis applying contingency theory indicate that local foods chains not only are short in structure. They are differentiated grounded in a developed local reputation. They also resemble in structure as well as operations more service supply chains than modernistic supply chains due of heightened reciprocal interdependencies demanding quality networking. The exchange economy is therefore vital in managing local foods logistics
Determinants of Sustainable Relationships in the Albanian Apple Production Sector
Get PDFThis paper analyses the behaviour of Albanian apple growers and their relations with buyers based on a structured survey. We develop a model of relational governance that highlights the importance of sustainable (lasting) relationships and draws upon different theoretical frameworks such as transaction cost economics and social network theory and focuses on determinants of relational exchange. The findings support the social network argument that the presence of verbal agreements between business partners strongly and positively affects exchange relationships. Asset specificity and competition among buyers also affects such relationships. The results and their implications at the management and policy-making level are discussed in detai
The Effect of Different Types of Diet on Greenhouse Gas Emissions in Greece
Get PDFDiet modifications are explored for the mitigation of greenhouse gases emissions worldwide. The current paper aims at estimating the carbon footprint of the diet of the Greek consumers in 2011. Based on food items consumption data, equivalent CO2 emission factors, the total carbon footprint associated with the per capita Greek diet patterns is calculated. Data for this task are retrieved from readily available resources of existent literature. The per capita carbon footprint resulting from the consumption of food items in Greece in 2011 for the reference scenario is calculated to be 1,827.4 kg CO2/y. In addition, alternative diet scenarios are proposed, their carbon footprint is calculated and suggestions are made for possible sustainable dietary changes. The results indicate that transition to a lacto-ovo-vegetarian diet constitutes a very drastic change towards mitigating greenhouse gases. However its acceptance by the public is very questionable. Thus, the second alternative scenario, which anticipates the substitution of beef by mainly pork and chicken, becomes more relevant. These results could serve as a yardstick for policy interventions aiming at reducing GHG emissions via diet modifications in Greece
Indicators of Beef Quality for Consumers: a Systematic Review
Get PDFQuality is a subjective term and means different things to different people. However there is general agreement that beef quality needs to be consistent, and needs to be improved. Furthermore, there is agreement that it will become an increasingly important factor in consumer decision making (Henchion et al., 2014). Informed by quality theory, this paper seeks to determine the relative importance of quality attributes from a consumer perspective through undertaking a systematic review of the literature on consumer attitudes to different beef quality attributes
An Investigation into the Dynamics of EU Agricultural Imports from Mediterranean Partner Countries
Get PDFThis contribution explores the buyer side of the value chains for the main agricultural products sourced from the Mediterranean Partner Countries (MPCs) in North Africa and Middle East into the EU, taking Spain as study case of these European import flows. Using the Global Value Chain (GVC) approach, it provides new survey-based evidence for better understanding and profiling the opportunities and constraints for these trade flows, and therefore deriving implications to improve the efficiency of the target value chains both in origin and in destination. Primary information has been gathered using two complementary methods. First, a buyer survey has been conducted through structured questionnaires directed to major Spanish importing and trading companies of orange, strawberry, tomato and olive oil sourced from Morocco, Tunisia, Egypt and Turkey. Subsequently, survey results have been supplemented by in depth, semi-structured interviews to a representative group of knowledgeable experts from the academic, public administration and business sectors. Results show differences depending on the product and the country studied. The approach used has been efficient in fulfilling the research objectives. It complements conventional quantitative inquiries where available evidence reveals serious difficulties to conduct thorough empirical analysis of the functioning of this trade with quantitative models. It is shown that the suggested approach is an alternative avenue to overcome these difficulties
Improving Value Chains for Dairy Farmers in Matiguás, Nicaragua: a System Dynamics Approach
Get PDFIn Nicaragua, the production of dairy and beef is the most important source of household income for many smallholder producers. However, erratic volumes and quality of milk limit the participation of small- and medium-scale cattle farmers into higher-value dairy value chains. This research uses a system dynamics (SD) approach to analyze the Matiguás dairy value chain in Nicaragua. The paper presents the conceptual framework of the model and highlights the dynamic processes in the value chain, with a focus on improving feeding systems to achieve higher milk productivity and increased income for producers. The model was developed using a participatory group model building (GMB) technique to jointly conceptualize and validate the model with stakeholders
Analysis of the Supply Chain and Logistics Practices of Warqe Food Products in Ethiopia
Get PDFWarqe (Enset) is a multipurpose perennial plant, domesticated and grown as a food crop only in Ethiopia. Kocho, bulla, and amicho are food products of warqe. This study analysed the supply chain and logistics practices of warqe foods. Supply chain management concept was used to analyse the warqe-based food chain. Eight supply chain actors were identified. It was observed that the supply chain of warqe foods and the relationship between chain actors was very complex, long and overlapping. The major constraints identified in the chain were poor information flow, poor transportation system, using perishable packaging, lack of cooperation between actors, a poor infrastructure such as road and warehouse services, and poor policies concerning the warqe market. There is a need for cooperation and coordination between the chain actors to create an effective information sharing system. Shared warehouses need to be built near producers and market places. Transportation, packaging and handling need to be improved. Research is required to develop an integrated, efficient and effective logistics for warqe supply and marketing chain

Conflict Resolution in Vertical Collaborations in the Agri-food Sector
Get PDFVertical collaborations in supply chains imply the achievement of mutual benefits for the participating partners such as increasing sales, reducing costs and risks and improving the overall performance. However, the benefits are sometimes difficult to gain due to existing differences in interests and goals of the individual chain members. Thus, conflicts are inevitable. Power can be seen as one of the mechanisms to resolve conflicts in supply chains. By and large, the findings provide support that power could have a profound impact on conflict resolution in vertical collaborations. However, in order to successfully resolve conflicts the knowledge of different power types is essential
