Over the last decades, the agriculture has experienced the development of several alternatives that aim to achieve sustainability, environment protection, farmers' livelihood improvement, etc. Amongst these alternatives, the “Conservation Agriculture” is expanding in many countries as an attempt to maintain soil fertility and prevent soil erosion through the application of principles such as minimal soil disturbance (zero-tillage), permanent soil cover and crop rotations. Based on an empirical case study that is being carried out in the South of Belgium, the paper discusses some questions raised by the Conservation Agriculture movement in the perspective of the theory of transition and its multi-level analysis (Geels 2007). - At first, it suggests to investigate the farmers' trajectories in the adoption of the Conservation Agriculture techniques as well as the building of the movement to see how individual learnings/lock-in affect the transition. - At a collective level, we want to understand how far the associations providing technique support, advices and information to the farmers could be a source of reflexive learning : indeed, Conservation Agriculture is an ambiguous approach mixing ecological concerns with business- and industrial-oriented practices such the use of Round Up Pesticide (chemical tillage) and time saving for big cropfarmers. - In Belgium, Conservation Agriculture is a “professional” initiative with weak visibility in the public sphere (compared to organic agriculture). What are the consequences of this lack of official recognition on the public debate about the future of agriculture ? - Further, the paper tries to highlight how the network or Conservation Agriculture has or not the ability to meet wider society's concerns such as the problem of mudslides in the countryside or use of pesticide. - And finally, through this multi-level analysis, we will address the question of the building of knowledge and know-how around Conservation Agriculture.

In order to handle future economic, social and environmental changes, the assessment, management and conservation of the local genetic resources of cash crop species is a fundamental requirement. We investigated the pattern of genetic and morphological diversity of Cananga odorata (Lam.) Hook f. & Thomson forma genuina, an important essential oil tree for the perfume industry in the introduction area of the western Indian Ocean islands. We sought to identify key elements for developing a conservation and management strategy for ylang-ylang genetic resources. Genetic and morphological variations were assessed using Amplified Fragments Length Polymorphism and morphometrics traits and information about farmers' practices were collected. The existence of substantial overall genetic diversity (HT = 0.2599) and the grouping of plantations into different genetic groups suggest that there have been a series of introduction events in the area, with limited exchanges of genetic material within and between islands, which is not what is suggested in the historical records. The morphological study revealed high phenotypic variability despite very similar agronomical practices throughout the studied area. The morphological and genetic variability might have been created and maintained without any planned or conscious management, and this has largely determined the genetic structuring in the area (11.74% genetic variation among islands and 20.68% among plantations). With this species, where past introduction events and farmers’ practices have shaped the genetic variation, on-farm preservation and the maintenance of the current management practices is recommended. Ex situ conservation efforts should also be undertaken, if economically affordable. [less ▲]

Recently adopted reforms of forest legislation in Central African countries take into account the interests of local communities. As organizations of different kinds have been promoting this aspect, all stakeholders of the timber sector are compelled to consider it. However, the practical implementation of this aspect often remains undefined. For vegetal NTFPs, the existing studies are typified by either a purely descriptive (ethno)botanical approach (lists of species used by an ethnic group) or by processing studies (transformation, conservation, economic value and commercialization of products) or by inventories defining the densities of certain species. Only a few studies examine the productivity of certain species. Within this context, one can conclude that there is a lack of studies that monitor the pressure exerted by local communities on the available products. The forest manager remains destitute while trying to monitor the level of exploitation of the ecosystem, while implementing a sustainable exploitation of the available resources or when he tries to set up conservation measures. This study aims at solving this problem. At first, a quantitative follow-up of the pressure exerted on vegetal NTFPs by a local Badjoué community living at the border of the Dja Reserve (Cameroon) is presented. This community of hunters and farmers (317 inhabitants) can be considered as representative of the way of life of many ethnic groups in rain forests. Pressure exerted is defined in terms of consumed quantities of each product and during several seasons. The consumed quantities are then converted into numbers of fructifying trees. Main results are twofold: on the one hand, the consumption of major exploited NTFPs can be expressed in terms of consumed quantities per habitant and per day during a certain period. On the other hand, we were able to calculate the number of tree stands that should be available to cope with the demands of the local community (with about 300 members). We could conclude that it is necessary — for our Badjoué community — to have 26 fructifying Irvingia gabonensis trees, 17 Baillonella toxisperma trees, 7 Ricinodendron heudelotii trees and 71 Trichoscypha spp. trees. Such research allows forest managers to consider the needs of local communities. Finally, the example of the Moabi (Baillonnella toxisperma Pierre) is chosen to illustrate the usefulness of this kind of approach for forest management planning. [less ▲]

Several species of wild animals are endangered with extinction in Cameroon. The ostrich, Struthio camelus, which is one of these animals, has been protected since 1994. In 2000, there were about fifty individuals left in the Waza National Park, in the far northern part of the country. The number of ostriches has steadily decreased in the park despite more than half a century of protection. This repressive management method has progressively evolved into a participative management method. The primary cause of this drop in number is poaching, which is carried out by the local populations searching for eggs whose shells are sold to tourists, and for adult animals killed for their meat, and even more so for their bone marrow which is widely used in traditional medicine. Commercial hunting is carried out by foreigners, the skin being used in the fabrication of hand-crafted objects. In addition to these problems, natural predation occurs, mostly by jackals, Canis aureus, and hyenas, Hyaena hyaena, which targets the hatchlings often already weakened by the harsh climactic conditions. One of the alternatives for the conservation of this species is the introduction of its breeding in “game ranching” or “game farming” near the park and urban centers where there are consumers of the products taken from this animal. The products of such breeding farms or ranches could be used as animals for reintroductions into the wild, improving the visual tourism, and be valorized on the national meat- and craft markets.

In this thesis, I study the stability of recognizability under arithmetic operations like addition, multiplication by a constant or multiplication, in an abstract numeration system. The main result presented in this work concerns the abstract numeration system built on the bounded language a^*b^*. It shows that, in this case, multiplication by a constant preserves recognizability if and only if this constant is an odd square. I end this text by providing some partial results of a generalization to abstract numeration system built on any bounded language. [less ▲]
