This study aims to analyze the evolution of the consumption of ready-made food in Belgium and to discern any trends. The data used are expenditure made on convenience food from 1999 and 2009 (in euros) and socio-demographic characteristics, obtained from the Household Budget Survey undertaken annually by the Federal Public Service Economy (DGSIE). Statistical analyses (simple, multiple and binary logistic regressions) enable the study of consumption trends in terms of exependiture and percentage of consumers as well as the determination of consumer profiles. Convenience food is part of the eating habits of Belgian households, with more than nine out of ten households being consumers. Convenience food prepared from meat is the most frequently purchased. For all ready-made food, the variable of household size explains the most variability in consumption, followed by the variables of income and age. [less ▲]

With the objective of determining whether it would be possible to sustainably produce Jatropha curcas L. seeds on the marginal land situated close to the Senegal River, a 6-hectare pilot plantation was cultivated under drip irrigation between September 2007-November 2011, close to the village of Bokhol (Lat. 16°31’N, Long. 15°23’W). A series of tests were conducted on this plot, in order to identify the best cultivation methods for the area (date, density and method of planting, appropriate type of pruning, fertilisers to be applied, irrigation method, etc.). The average yields obtained at this site, after four years of cultivation (less than 500 kg.ha-1 of dry seed), using the best known production techniques, are significantly lower than anticipated, compared to the available figures for the irrigated cultivation of Jatropha in other parts of the world. The main causes of this failure are the plant’s limited useful vegetation period of six months per year, instead of twelve, and the scale of attacks by a soilborne vascular disease, which destroyed over 60% of the plantation within four years.

Jatropha curcas L. seed oil is proven to be toxic to many microorganisms, insects and animals. Despite its toxicity, Jatropha is not pest and disease resistant. The following major pests and diseases affecting Jatropha in the lower valley of the Senegal river have been identified: the leaf miner Stomphastis thraustica (Meyrick, 1908) (Lepidoptera, Gracillariidae), the leaf and stem miner Pempelia morosalis (Saalmuller, 1880) (Lepidoptera, Pyralidae) and the shield-backed bug Calidea panaethiopica (Kirkaldy, 1909) (Heteroptera, Scutelleridae), which can cause flower and fruit abortion. Damage from these pests was particularly great during the second year after the plantations were set up (2009) and before later receding. Nevertheless, the worst attacks were caused by a vascular disease transmitted through the soil, which killed 65% of the plants in four years. It is mainly characterised by collar and root rot, which causes foliage to yellow and wilt, before the plant eventually dies. These threats should increase if larger areas are planted with Jatropha. Considering the scale of the damage caused by these attacks in Bokhol, the development of an integrated pest management programme adapted to the local context should be considered. [less ▲]

This master thesis presents two projects of Jatropha curcas plantations that have been set up in 2007 in Senegal. The first project consists in rural trials under rainfall irrigation (800mm of precipitations spread on 5 months) that take place in Dialacoto. The second project consists of an experimental field under drip irrigation set up by the Durabilis Foundation in Bokhol (200mm of precipitations spread on 3 months). In that work are developed some key points for a successful Jatropha plantation. For the traditional agricultural system under rainfall irrigation, it is important to: (i) clarify the modality of land appropriation and use while starting a Jatropha plantation in order to avoid land property conflicts, (ii) make sure that farmers could maintain the plantations and protect them against cattle, (iii) set up the new plantations as soon as possible at the start of the rainy season to ensure a good development of the plants before the dry season. For the intensive drip irrigated systems, positive responses to different experimentations have been noted. Plant growing seems better when: seeds are planted in PET containers in a shaded nursery, plants are grown with input of manure and chemical fertilizer. Some cutting techniques promote the number of ramifications on a plant. We also observed variable response of growing parameters for different origin of plants; it means that plantation must be set up with an adapted vegetal material. Three pests of Jatropha have been observed in Bokhol (two lepidopteron and one true bug) which could cause valuable damages to the plantations. [less ▲]
