This article analyzes how value chains play a role in the political economy of agricultural and food policy by (1) discussing historical insights; (2) reviewing an emerging literature on trade drawing implications for policy; (3) market power issues with increasing concentration agri-food its government regulations; (4) presenting case study recent regulations that have explicitly targeted chai...

Livestock-associated methicillin-resistant Staphylococcus aureus (MRSA) have been found in various farm animal species throughout the world. It was the objective of this study to estimate the prevalence of MRSA in different cattle food chains (milk, beef, and veal) in Germany, to analyze the MRSA diversity along each food chain and to compare the characteristics of the different subtypes. Sampl...

Sustainability assessment is one of the keys to competition by food supply chains over sustainability. The way it is conceived and embodied into decision-makers’ choices affects the competitiveness of local and global chains. Science-based assessment methodologies have made substantial progress, but uncertainties—as well as interests at stake—are high. There are no science-based methods that ar...

Globally, natural resources are increasingly under pressure, especially due to population growth, economic growth and transformation as well as climate change. As a result, the water, energy, and food (WEF) nexus approach has emerged to understand interdependencies and commonly manage resources within a multi-scale and multi-level framework. In Sub-Saharan Africa, the high and growing consumpti...

in order to achieve the research objectives, the determinants of framework for assessing the sustainability of food supply chains, literature reviewed and then sustainability assessment framework of food and agriculture organization (fao) introduced as a research basic model. localization and verification of research criteria by using the delphi technique and calculation the importance degree o...

Local food has recently gained popularity under the assumption that it is more sustainable than food from distant locations. However, evidence is still lacking to fully support this assumption. The goal of this study is to compare local and global food chains in five dimensions of sustainability (environmental, economic, social, ethical and health), covering all stages of the chain. In particul...

Metabolism of living organisms is a foundation of life. The metabolic rate (energy production per unit time) increases slower than organisms' mass. When this phenomenon is considered across different species, it is called interspecific allometric scaling, whose causes are unknown. We argue that the cause of interspecific allometric scaling is the total effect of physiological and adaptation mec...

We study optimal birth policies for an age-dependent n-dimensional food chain model, which is controlled by fertility. New results on problems with free final time and integral phase constraints are presented, the approximate controllability of system is discussed.

The quality of the final product, as well as the efficiency of a chain in terms of losses and costs of wastes, depends on actions and practices that happen in the agents and in the transactions along the whole productive chain. It is with base in those presuppositions that the present article aims at to propose a managerial method to aid in the coordination of the product quality along agricult...
