Full textThe mexican vegetable and fruit markets are characterized by an offer artificially maintained under the solvable demand by the main agents or groups involved in these commodity chains. The principal wholesalers and the important producers based in the heart of the organization get the essential part of the income coming out of this situation. The small and average dealers or brokers and above all the small vegetable producers are often out of the sharing of the benefits, on the outsirkts of this organization where the risks are much higher. These peasants are involved in the organization of the production within the lands of a community (a case study is proposed about tuxcacuesco in the south of jalisco). The agrarian reform gives them lands; the government build irrigation units allowing them to start intensive cropping (vegetable). Access to the principal means of production (lands and water) depends on the hierarchic relationships reigning in the community, migration and the development of vegetable production bringing a new source of accumulation. The production risks and above all the marketing ones compel the farmers to adopt different strategies depending on their productive means and their preferences. Some wants to realize a better insertion in the commercial outputs helped by transport facilities and privileged relations with the dealers. Thus they leave the fringe where the vegetable producers are competitive among themselves. However the exchange terms remain favorable to the wholesalers except in case of insufficient production, they maintain the offer level by controlling the negotiation point because of the absence of imposed norms that compels the passage through the main markets
dreux, Nicolas. "Transfert et survie de Listeria monocytogenes dans l’environnement des cultures maraîchères." Université d'Avignon et des Pays du Vaucluse, 2007. http://www.theses.fr/2007AVIG0719.
Full textThe survival and the transfer of Listeria in soil and on leaves were studied in open field and laboratory conditions. Studies in open field conditions identified the spreading of organic fertilizers and sprinkled-irrigation as agricultural practices contributing to the presence of L. Monocytogenes on produce. A higher relative humidity as well as a cooler climate would contribute to increase its survival. However, even with a high inoculum, Listeria did not persist in the environment of vegetable crops for long periods (decrease of 7 log in 63 days in the soil and of 9 log in 2 days on the leaves). In the laboratory, L. Monocytogenes was able to multiply on parsley leaves under satured relative humidity whereas its declined rapidly under low relative humidity (4-5 log in 8 days). However, under low relative humidity, a non-culturable viable population (VNC) of L. Monocytogenes remained on the leaf surfaces. This population of VNC did not seem to be able to recover its culturability when the parsley leaves were placed under satured relative humidity. The investigation of mechanisms involved in survival of L. Monocytogenes on parsley leaves under low relative humidity showed 1) the role of the alternative sigma factor B in the persistence of L. Monocytogenes on the parsley leaves; 2) the implication of the Fri protein in the persistence of VBNC L. Monocytogenes and 3) a protective effect of glycine betaine on L. Monocytogenes on the parsley leaves. The protective effect of the glycine betaine on L. Monocytogenes was not due to an intracellular accumulation by the uptake systems BetL, Gbu and OpuC

Full textGeminiviruses have emerged to become one of the largest and most economically important groups of plant-infecting viruses, and geminivirus-induced diseases are a major threat to worldwide vegetable production, particularly in tropical and subtropical regions of the world. Importantly, the accumulated body of work on some of the most important geminiviral associated diseases clearly demonstrate the role of geminiviruses associated with wild plants on the emergence of disease on imported crops. Moreover, recent metagenomic data suggested that the vast majority of viruses characterized from crops represent only a small fraction of the phytoviruses in general. It is therefore of prime interest to obtain a better knowledge of viral diversity infecting crops and wild plants, the main epidemiological parameters involved in their emergence and their dynamic at the scale of agro-ecological systems. In this work, a survey of solanaceous crop fields and their surrounding uncultivated plants from 48 localities in Burkina Faso and Ivory Coast was performed. The sample analysis using classical molecular biology tools both confirm the incompleteness of our knowledge of the geminivial diversity and the existence of numerous alternative wild host plants. At least five species of begomovirus and mastrevirus were found in association with the ToLCD-TYLCD. A North to South increasing gradient of complexity of viruses populations was uncover with PepYVMLV being the most prevalent on cultivated solanaceous plants. The discovery of the association of a newly described DNA-B component with the PepYVMLV also lead to the study of the epidemiological parameters of this co-infection. Despite this association being relaxed, it was demonstrated that the virulence of the disease, the viral accumulation and the transmission by Bemisia tabaci were increased with the presence of the co-infection with the DNA-B component. All these factors are probably associated with the success of this association on the field. Because of the extreme severity of the resulting disease, the diffusion of this new DNA-B component at a larger scale would represent a major threat to tomato culture in Burkina Faso, Africa and the world in general. The use of a metagenomic approach, allow the generalization of our findings to full agro-ecological settings. Besides confirming previous species discovery, species yet undescribed in Burkina Faso along with completely new begomovirus species were described. The inspection of the virus-plant and virus-virus associations networks allow to uncover strong links existing between the viral corteges associated to groups of cultivated and uncultivated plants. These findings emphasized the necessity to consider full agro-ecological settings plant diversity rather than only crops in order to understand and prevent geminiviruses associated diseases. Globally, our results highlight the necessity to carry on the ongoing plant disease monitoring work and the inventory of viral populations associated with cultivated and uncultivated plants in order to understand the functioning of natural geminiviral community and the impact of human practices on the emergence of viral disease

Full textIn the context of the environmental and social challenges of the Anthropocene, microfarms are organic market gardens which are questioning the principles of agricultural modernisation. They are characterised by a high level of crop diversity on small acreages, low motorisation, holistic ecological approach and marketing through short supply chains. My PhD work examined the viability of these atypical farming systems which are raising an increasing interest in industrialised countries. It was based on the study of 20 cases in rural Northern France and 10 cases in the urban context of London. An inductive approach was carried out combining qualitative analysis of interviews with farmers and quantitative modelling based on field data.A conceptual framework was developed to analyse farmers’ strategic choices in the light of their life project embracing various aspirations where ethics and subjectivity played a central role. The fulfilment of these aspirations is determinant for the viability of these fams. A stochastic simulation model of income and workload was created to explore the chances of economic viability of contrasted microfarms scenarios integrating technical, commercial and investment strategies. Simulations were run for the French and London context and were discussed with stakeholders. Although viability chances vary among scenarios, this work shows that microfarms can be viable
