The analysis of the world sugar sector shows a trend of conversion to bioethanol production. At the root of this transformation lie the volatility of sugar prices on the world market and the desire to reduce dependence on oil from some countries exporting sugar. The prices volatility also explains the use of sweeteners in place of sugar, especially in the food industry. The development of bioethanol production from sugar is now favoured by the reform of the sugar market in Europe and the renewed interest of several countries for cleaner renewable energy. © 2007 John Libbey Eurotext.

Objective: Consumption of fruit and vegetables (F&V) may play a role in the fight against overweight. The aim of the current study was to validate the link between consumption of F&V with overweight and biological impact. The Algerian context is a very rapid transition with a high prevalence of overweight and low consumption of F&V. Methodology: Qualitative and quantitative surveys were conducted on 421 persons in urban (200) and rural (200) areas. Experimentation on 40 persons in Adj El Mechri (South Algeria): Distribution of 400 g/capita/day of fruit and vegetables during 2 months. Results: (i) Link between consumption of F&V and the prevalence of overweight is not as obvious as it seems. Three types of people emerge: (a) urban people with a high level of F&V consumption and a normal body mass index, (b) the illiterate urban people with a low consumption of F&V and prone to obesity, (c) the rural elderly, primary school level people with a pre-obese status. (ii) Some physiological and behavioural impacts of increased consumption of F&V were validated: vitamins E and B9 have increased; blood pressure was improved; pre-obese people lost weight while obese persons have increased their weight because the quantity of F&V consumed was added to the usual ration. (iii) Increased availability of F&V was appreciated and did not disrupt the behaviours. Low consumption of F&V was due to their limited access (low income, high prices, low availability and lack of variety).

The problem of internal migration and its effect on urban unemployment and underemployment has been the subject of an abundant theoretical literature on economic development. However, most discussions have been largely qualitative and have not provided enough rigorous frame-works with which to analyze the mechanism of labor migration and urban unemployment. In this paper, we build up an economic behavioral model of rural-urban migration which is an agent-based version of the analytical Todaro model described by deterministic ordinary differential equations. The agent-based model allows to explore the rural-urban labor migration process and give quantitative results on the equilibrium proportion of the labor force that is not absorbed by the modern industrial economy. © 2010 Springer-Verlag Berlin Heidelberg.


Over the last decade, Algeria has encouraged the adoption of water saving systems by providing subsidies to fanners through a national plan for agricultural development, with particular attention paid to drip irrigation. This initiative has been successful only for a limited number of farmers. This work aims at analysing the determinants that influence the Algerian farmers in converting to the drip irrigation system. This work is based on a model (Logit) that allowed us to identify variables significantly influencing the innovation behaviour of fanners regarding the decision to adopt the system. The results show that subsidies, type of crop and educational level have positively affected adoption. However, the investment costs, conditions needed to access and lack hydraulic structure seem to have a negative affect the adoption drip irrigation.
