Regional modelling for optimal allocation of agricultural crops considering environmental impacts, housing value and leisure preferences
Regional planning should consider the impact of agricultural crops on housing value and leisure, as well as on the local environment. We designed an optimisation model for allocating agricultural crops based on farmers' profits as well as the impact on these three factors. Each crop creates a different landscape, as well as a different effect on shading and noise reduction. This in turn ...

Are genetically modified (GM) crops a commercial risk for Africa?
What risks might Africa face if it decided to plant genetically modified (GM) agricultural crops? A rough calculation based on current export profiles for one sampling of eastern and southern African countries suggests that the commercial export risks incurred outside of Africa would be quite small. Most of Africa's exports of goods that might be considered GM currently go to other African ...

Attitudes of farmers toward sludge use in the Gaza Strip
The local production of organic fertiliser in the Gaza Strip is 66,800 m³/year, which represents only 8.5% of the required quantities. This means that farmers have to import 728,000 m³ of organic fertiliser per year, which costs around 10.2 Mio US$. The social survey carried out for more than 300 farmers in the Gaza Strip shows that the scarcity of organic fertilisers and their high prices could ...

Factors influencing the conversion to organic farming in Norway
Determinants of the decision to convert to organic farming methods are examined by applying bivariate analyses and a multinomial logit model to a survey of 1018 Norwegian crop and dairy farmers. The results show that 4% of the conventional respondents plan to convert by 2009, which may imply that the national goal of 10% organically managed area will not be achieved. The analysis indicates that ...

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 ...
