A differentiated account of the role of trust in consumers' acceptance of genetically modified foods in Germany
This paper proposes a sequential model to contrast the causal chain and associationist models on the role of trust in GM food acceptance. Data from 60 laddering interviews suggest the role of trust in evaluating the perceived consequences of GM food production and consumption is small and that the link between risk and trust is rather weak, too. Lending further support to the relevancy of the ...

Changes in chlorophyll, anthocyanins and phenolic compounds concentration in fresh–cut onion
The minimal processing of onion is practical and convenient to consumers, eliminating the inconvenience of peeling, cutting, unwanted odour and tearing effect. The study aimed to estimate the levels of chlorophyll, anthocyanins and phenolic compounds in fresh–cut onions, triturated in the form. Onions, white and purple, obtained in Pombal–PB were conducted in the Laboratory of Food ...

Intensity of Italy's agri–food trade with countries outside the EU Mediterranean
This paper aims to present a framework of trade relations between Italy and the countries of southern and eastern shores of the Mediterranean Sea. More specifically, using the indicators proposed in the analysis of international trade, we want to analyse the intensity of trade in agri–food products and the strength of trade ties between the bordering Mediterranean countries. The analysis of the ...

Economic partnership agreements, common external tariff and prospects for staple food items in Nigeria
This paper looks into the potential impacts of the proposed Economic Partnership Agreement (EPA) between African, Caribbean and Pacific countries and the European Union (EU) on agriculture and food production in Nigeria. Using a partial equilibrium analysis, it assesses possible changes in production arising from the implementation of a Common External Tariff (CET) and/or EPA on three crops ...

A risk assessment of the food supply chain: vulnerability against terrorist or criminal contamination
The food supply chain has been recognised by the USA and the EU as a critical infrastructure, and it should be considered a target for possible terrorist attacks. In this paper, we present a methodological approach developed within the EU project SecuFood to evaluate the risk associated with this threat. The usefulness of the approach is related to the improvement of the analysis of food supply ...

Using land-time-budgets to analyse farming systems and poverty alleviation policies in the Lao PDR
This paper applies the method of 'Land-time-budget analysis' to a rural subsistence community and to the national economy of the Lao PDR. The analysis is conducted to meet two ends: to identify the community's/the nation's resource use profile in terms of land and time use - the analysis identifies biophysical constraints of socio-economic development and trade-offs in resource use patterns; to ...

Bats at risk? Bat activity and insecticide residue analysis of food items in an apple orchard
Although bats are reported as being threatened by pesticides, they are currently not considered in European Union pesticide risk assessments. The reason for that contradiction is probably related to the scarcity of information on bat activity in pesticide‐treated fields and the pesticide residues on their food items. The authors recorded bat activity and measured pesticide residues on ...

Hazard and Critical Control Points of Ready-to-Eat foods and an abattoir examination in a typical tropical market
Ready-to-Eat (RTE, street) foods sold at Bodija market, Ibadan, Nigeria were examined. Methods used for the preparation of RTE foods were followed in establishing relevant Critical Control Points (CCPs). Hazard analyses were carried out on all foods examined from the raw material up to the finished product levels. Two cereal-based products (kokoro and kunu tsamiya) had high microbial counts (>104 ...

Residues of organophosphorus pesticides in different food commodities in Slovenia, 1997?1998
During the period 1997?1998, a total of 1237 samples of different food commodities were analysed for residues of organophosphorus pesticides in Slovenia. The domestic and imported commodities tested included fruits, vegetables, cereals, alcoholic drinks and food of animal origin such as liver, fish, eggs, milk and honey. Residues of organophosphates were detected in 8.2% of samples (101 samples). ...

One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas
All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. This figure doubles when looking at irrigated cropland, which produces 40 ...

Goat Farming - Impacting Livelihoods
Goat Farming – Impacting LivelihoodsGoat farmers could earn 250-300% higher incomes from goat rearing only by adopting scientific norms of goat management and potentially higher by improving herd size and engaging in goat rearing as an enterprise by rural households.Continued innovation is needed for better technology acceptance by all stakeholders. ...

Organic production: the adoption of a niche strategy by the mainstream food system
This paper critically assesses the potential and barriers for food system transformation from the conventional to an organic model by utilising the literature on system innovation. Based on the analysis of two food supply chains in the UK, namely chicken and potato production and processing, the paper demonstrates that the current conventional food system appears to be resilient to radical ...

The organic food market in Portugal: contested meanings, competing conventions
The European Union regulatory framework on organic farming gave a new impulse to the institutionalisation of the Portuguese organic farming movement. This paper offers an analytical account based on interviews with key market and institutional actors within the organic food sector in Portugal. The qualitative analysis undertaken is underpinned by the premises of convention theory and aims at ...

Projected mercury dietary exposure of three bird species nesting on a contaminated floodplain (South River, VA, USA)
Dietary mercury exposure was modeled for Carolina wren (Thryothorus ludovicianus), Eastern song sparrow (Melospiza melodia) and Eastern screech owl (Otus asio) nesting on the contaminated South River floodplain (Virginia, USA). Parameterization of Monte Carlo models required formal expert elicitation to define bird body weight and feeding ecology characteristics because specific information was ...

Seed systems for African food security: linking molecular genetic analysis and cultivator knowledge in West Africa
A challenge for African countries is how to integrate new sources of knowledge on plant genetics with knowledge from farmer practice to help improve food security. This paper considers the knowledge content of farmer seed systems in the light of a distinction drawn in artificial intelligence research between supervised and unsupervised learning. Supervised learning applied to seed systems ...

Cadmium toxicity in plants
Cadmium is a heavy, non-biodegradable metal that is toxic to plants, people, and animals. With increasing pollution and emission of cadmium, its levels in agricultural soils are increasing. The risk to humans is high due to consumption of cadmium-contaminated food. Modern applications of gas analysis and laser measurements are speeding up research in addressing the problem of cadmium stress. ...
