Agricultural Value Chain for Food Security: Challenges and Opportunities from SDG2
2019
The objective of this text is to provide non-economists with an analytical tool by which to understand various aspects of how contemporary agriculture and agribusiness systems function. It will begin by outlining Porter’s value chain paradigm and Porter’s value system. Thereafter, there will follow an overview of the meaning of agricultural value chain (AVC) and its main features.
The Cereal Market and the Role of Fermentation in Cereal-Based Food Production in Africa
2014
Cereals represent the main crop in Africa (45% of arable land) and make an important contribution to the human diet in this continent. Cereals for humans are not consumed raw. Fermentation technology is widely used in Africa to transform cereals into edible products as well as to preserve and enhance the nutritional and safety aspects of cereals. In general, in Africa, this process is not controlled and is devoid of good manufacturing practices (GMPs). Spoilage and/or pathogenic microorganisms may compromise the final quality when the fermentation is not controlled. This article focuses on the role that the fermentation process could play in creating safe food conditions in Africa. Taking i…
Liquid chromatography-mass spectrometry in food safety.
2010
Abstract The use of powerful mass spectrometric detectors in combination with liquid chromatography has played a vital role to solve many problems related to food safety. Since this technique is especially well suited for, but not restricted to the analysis of food contaminants within the food safety area, this review is focused on providing an insight into this field. The basic legislation in different parts of the world is discussed with a focus on the situation within the European Union (EU) and why it favors the use of liquid chromatography–mass spectrometry (LC–MS). Main attention in this review is on the achievements that have been possible because of the latest advances and novelties…
Special issue on Trends and challenges of sustainable irrigated agriculture
2014
In the twenty-first century, the shortage of freshwater is one of the most important environmental concerns facing several regions of the world because of the growing demand of increasing population, agricultural intensification, and economic growth. Global climate change will contribute to exacerbate the problem, generating new drought-prone areas and increasing those already characterized by severe aridity. Worldwide it is estimated that, on average, agriculture accounts for 70% of the total water consumption, compared with 10% for domestic consume and the remaining used by industry. Moreover, according to FAO estimates, by 2050 agricultural production has to increase by 60% to satisfy th…
Hunger and Food Charity in Rich Societies: What Hope for the Right to Food?
2014
First World Hunger: Food Security and Welfare Politics (Riches, 1997a) offered the first cross-national study of the emergence and entrenchment of food aid and charitable food banking from the early 1980s to the mid-1990s. It consists of five case studies from advanced industrial countries with developed ‘liberal’ welfare states: Australia, Canada, New Zealand, the UK and the USA. All of the countries were food exporters and food secure through national production and imports, suggesting that domestic hunger could not be caused by the failure to provide sufficient food and nutrition, but rather was a matter of distributional justice and human rights — that is a fundamentally political issue.
Transforming Food Systems at Local Levels: Using Participatory System Dynamics in an Interactive Manner to Refine Small-Scale Farmers’ Ment…
2016
Food systems will need to undergo considerable transformation. To be better prepared for and resilient to uncertainty and disturbances in the future, resource users and managers need to further develop knowledge about the food and farming system, with its dominating feedback structures and complexities, and to test robust and integrated system-based solutions. This paper investigates how participatory system dynamics modeling can be adapted to groups at the community level with low or no formal educational background. The paper also analyzes the refinement of workshop participants’ mental models as a consequence of a participatory system dynamics intervention. For this purpose, we…

Transformation of Agricultural Markets: Trends, Drivers, and Implications for SDG2
2019
The objective of this text is to provide noneconomists with an analytical tool with which to understand some of the more important trends in the food system and to improve the interpretation of the complex and rapid changes to which this field is subject. The text will begin with a general description of the main characteristics of traditional agricultural markets and then examine modern agricultural markets and related issues, such as industrialization and globalization. Finally, the text will address some of the implications of recent events in global agricultural markets regarding food security and the goal of zero hunger.
Uncertain sunset lives: British migrants facing Brexit in Spain
2020
One of the most concerned groups potentially impacted by the approval of Brexit in 2016 is that of the so-called “Brexpats”. This group of people is composed by at least 784,900 British citizens who are living in the European Union (EU), among which those settling in Spain are the most prominent. Spanish Brexpats are the largest British population outside the borders of the UK, except for in the Commonwealth territories. They have some peculiar characteristics, such as an advanced average age compared to other EU destinations; a large number of people living off the radar; geographical concentration within coastal areas; and a certain social isolation. In this context, the succession of new…
L'intervento francese in Mali si basa su un'autorizzazione del Consiglio di Sicurezza?
2013
Il lavoro affronta la questione del fondamento giuridico dell'intervento militare della Francia nel Mali del gennaio 2013, soffermandosi in particolare sulla questione se tale fondamento possa essere rintracciato in un'autorizzazione implicita del Consiglio di Sicurezza delle Nazioni Unite.
