Sandoz, Alain. "Proposition d'une méthodologie adaptée au suivi de l'occupation du sol d'une zone humide aménagée : application au bassin du Fumemorte (Grande Camargue,France)." Aix-Marseille 1, 1996. http://www.theses.fr/1996AIX10023.
Full textThe objective was the development of a methodology adapted to the monitoring of land use in wetlands, which should be applied for various space and time units. Two main tools are used for this purpose : satellite remote sensing and georeferenced data bases. The experiment was conducted on a drainage basin, the fumemorte catchment in the rhone delta. The use of historical or newly acquired data is illustrated with some examples concerning the agricultural sector of the catchment and marshes of the tour du valat estate. In these examples, data from satellite images processing are integrated with other spatialized data. Results demonstrate the capabilities of the method for the monitoring of this particular environment, and for the interpretation of the data

Full textThis thesis describes the different historical stages of heritage landscapes of Perfume River in Hue in the central of Vietnam. The research hypothesis defend that the meaning of the famous site of the Perfume River, as both symbolic, imagery and materiality of a river was built culturally, socially and politically as a set of landscapes for transmit. It’s shown that three steps were undertaken: first, cosmological and poetic of the Nguyen dynasty times in XIX century, then the picturesque form during the colonial period, and finally the juridical mode in the list of World Heritage in 1993. These steps are added to each other in the imagination of local collective, provincial and national levels to get a reference to the current ecomuseum project which should allow the implementation of a policy for the inventive landscape conservation site in an orientation of tourism development

Full textThe objet of the study is related to the research on a coviability between humans and ecosystems within a sahelian context whose environmental, socioeconomical and political data have deeply evolued since at least twenty years. An approach based on the anthropo-juridical study of the various exploitation systems and their interactions infers the fundamental imbrication of the land (defined as the substrate support of the biotic elements and the ecological process) and of the environment (composed in particular of the renewed resources as stakes of power relations). This approach in environmental law is made from a methodological attitude taking into account three observation scales : the village territory, the province and the region. Constituing the binomial spaceresource as unit of observation and as operative concept in every scales, it explores the relation man-natural environment by decorticating the land tenure frame of each of the exploitation systems taken individually and in interaction with the others. The aim is to think the principles of a right considering the interactions which weigh on the behaviour of individuals, on their decision and their action in terms of management of natural resources and which integrate the necessity of the longterme coviability of the biodiversity and of the cultural diversity. This right should constitute a change lever and allow to move from the conflicting and disorganized situation that the analysis of the social structures shows to a juridical situation where the liberty margin of the social actors and their respective responsability shares are clarified in accordance with the rights they have on the space-resources and in which they must be, in other respects, secured

Full textProcellariiformes are seabirds showing a set of characters rendering them particularly attractive to research. They are the most diverse seabird group, and probably also the most threatened, with 44. 7% species classified Vulnerable or worse under IUCN criteria. As many seabirds, they are fascinating models to study patterns and processes of population and species differentiation, being under contradictory evolutionary forces: on the one hand being extremely vagile allow them to disperse very far, which is supposed to enhance gene flow between populations, thus reducing their differentiation and diversification ; on the other hand, being extremely philopatric, they often return to breed in their natal colony, a pattern supposed to enhance population differentiation. Living in the ocean, they also constitute good models to investigate differentiation processes in the absence of physical barrier to gene flow. In addition, partly as a result of the opposite evolutionary forces just described, their taxonomy and phylogenetic relationships are complex, have proved very frustrating over the decades and have therefore been in a state of flux over the years. The development of molecular ecology in the last two decades have provided some new powerful tools to elucidate some of the phylogenetic uncertainties, to understand the observed phylogeographic patterns and have a better grasp at the underlying processes promoting diversification in these birds. These tools also allow a better understanding of population structure and relationships and can greatly help to the prioritisation and design of conservation actions directed at conserving these organisms. In this thesis, by means of molecular ecology tools, I investigated the phylogenetic relationships and phylogeography of several taxa belonging to family Procellariidae, the most speciose in order Procellariiformes. I studied these at two levels: first at the genus level by describing phylogenetic relationships in genus Pseudobulweria, probably the most endangered seabird genus in the world; and second at the taxon and population level I focused on the Macaronesian group of gadfly petrels and on the Gould’s petrel complex, in particular regarding the relationships between its Australian and New Caledonian subspecies. Using a multiloci approach for each of these investigations provided a mean to improve our understandings : in Pseudobulweria the species tree approach used allowed inferring the phylogenetic relationships between all the taxa in the genus for the first time and to solve a taxonomic issue regarding the status of Beck’s petrel ; in Northeast Atlantic gadfly petrels, I showed that the divergence of the three taxa living in that region is much more recent than previously thought and that the three populations deserve at least the status of Evolutionary Significant Units ; in Gould’s petrel I showed that the two population currently recognised as subspecies are not structured genetically and the lineages have not diverged. These investigations underline the necessity to incorporate new methods and multiple loci when investigating the phylogenetic and phylogeographic patterns in organisms to fully capture their complexity

Full textIn the right heart of the african continent, the sub-region of Central Africa has important natural resources. Unfortunately, those resources are lately facing an irrational exploitation, portending an environnemental situation of crisis in a short term. Aware of those threats, Central African's States and international community multiply many-sided strategies in order to reverse the tend. Many initiatives are recorded during the last years as much at the level of management political review as regards operational activities. This study tries to review some of them and show how Central African's States and civil society work hard, with the help of many internationals partners, to safeguard natural resources in prospect of a sustainable development. In this part of the world, the international environmental law doesn't stay on a theoretical level, but found expression in some concrete and field realizations

Full textDoes everything have to change for everything to stay as it is ? The Law of the Sea is subject to continuous development to maintain the balance between freedom of resource exploitation and emerging environmental pressure. But does everything has to change ? The aim of this study is to get to the heart of the matter, especially regarding state responsibility in the conservation of marine biological resources in areas beyond national jurisdiction. Between crisis and evolution, the law of the sea has to find its feet regarding the challenges the international community is facing. In order to maintain a sustainable conservation of resources, the consideration of common interest and environmental requirements has led to a reconceptualisation of state responsibility, where international cooperation has its importance. The Law of the Sea has thus made their own and updated some international law and environmental law concepts, through emerging mechanisms to initiate new forms of state responsibility

Full textMediterranean sea is actually suffering from an overfishing of its resources because of a lack of an international control policy of its fisheries. There is urgency and at the same time difficulties to cure this delicate situation, so many are the conflicts between traditional fisheries and states in Mediterranean sea. It seems impossible to adapt the oceanic fisheries control policy to the Mediterranean sea. The only solution is to create a project of partition of its natural resources from the new international law of the sea and concept of enclosed sea

Full textEuropean heathlands were maintained by traditional agro-pastoral practices over the last 3000 years. Since 1950s, these traditional land uses have almost completely disappeared. As a result, heathland areas have been drastically reduced and have been overrun by grasses and woody species. Heathlands conservation requires consistent and permanent management action to control the natural succession. The ‘Trois Pignons’ forest (Fontainebleau, France) consists of a mosaic of heathlands and forests which are integrated into the Managed Biological Reserves (RBD). Since 1992, the managers of this RBD aim to maintain heathlands. In this context, we study in a first part, heathland vegetation dynamics at different spatial and temporal scales. Results show a gradual change from Ericaceae species in pure stand to a mosaic of grasses and Ericaceae, despite the application of measures to maintain this habitat in managed heathland. The development of grasses is correlated with thinness of the spatial variability of soil properties and the spatial variability of reforestation. In a second part, we assess changes in forest cover between 1946 and 2003. Results show the loss of 60% of heathlands during 1946–2003 associated to a similar increase in forest areas and the persistence of C. Vulgaris in coniferous stands and young mixed stand. We also study relationship between landscape spatio-temporal heterogeneity and biodiversity in mosaic-landscapes. The results indicate that in the areas of high spatio-temporal heterogeneity, a general increase is observed in species richness, in particular for vascular plants, bryophytes and carabids. The study demonstrates how spatial methods can contribute to the design of reliable management methods of habitats such as the heathlands, and enable us to offer recommendations as to how to better manage heathland semi-natural habitats of the Fontainebleau forest and elsewhere in Europe

Full textThe environment’s protection does not have any more cease to be a priority for the subjects of the International law. Since the Summit of Rio de Janeiro on the environment and the development, this concern caused at the international level was taken more and more into account by the States. Cameroun did not remain with the margin of this process since many legal provisions were taken in order to protect nature and its resources in fact those consisted wild fauna. Indeed, while taking as a starting point the International law of the environment, the Cameroonian legislator devoted the principle of conservation of wildlife by recommending the control of hunting activities, by attaching a major importance to the protected areas and by controlling the use of the faunal resources at commercial purposes. These measurements were also combined with the other supposed ones to improve the living conditions of the autochthon communities like the facilitation of the access to the natural resources and the implication of those in the management of wild fauna. However, this regulation knows important limits primarily made up by the restriction of the principle of participation and the multiple difficulties of a functional nature. All these limits result in to relativize the results obtained by the policies of conservation of fauna and promotion of the rights of the autochthon communities to Cameroun. To ameliorate the situation, of important measures should be taken in particular the improvement of decentralization’s policy, the participation’s principle reinforcement, the reinforcement of the control of the commercial exploitation of the wildlife resources and the at last, the equipment of autochthon communities of a clear statute taking that is taking in consideration their particularities

Full textThis thesis under CIFRE contract aims to offer a methodology to change shore underwater marine systems into artificial habitat for ecosystem and fisheries exploitation. The objective is to give additional tools and answers to professionals specialised in fisheries and ecosystems management. The methodology is geo-systemic, it aims to integrate these changes into the ecosystem and socio-economic systems of artisanal fisheries (strategy type ICAM). The studies conducted on site in Japan taught us how to handle the integration of the underwater world through the relationship between species and their living space. This approach leads us to change the concept of "artificial reef" to the concept of "artificial habitat" as living spaces adapted for species living in a shore environment. The comparison of techniques from Japan, Portugal and France (the priority for these countries is to improve their marine parks with artificial habitat in order to help fishery related professions) helped us to identify a lack methodology in France. It is this global methodology that we want to define. The essence of this methodology is based on the relationship between society and nature at two levels : biophysical and socio-economical. It's organised by typology of artificial living space. Its application on one case study allows us to understand its limits and the necessity to define a common way of using such spaces. AH are participative transactional tools during concerted phases. We demonstrate that the wish to improve underwater living spaces enables the limitation and familiarization of shore territories which was until now unknown. The preservation of the shore ecosystems made possible by this methodology could assist in a balanced development of territorial collectivities

Full textAn important step in the elaboration of a new juridical logic essential to the construction of an order respectful of ecological balance was taken with the acknowledgement of the principle of rational use in international law and its introduction into the internal law of numerous countries. If one bears in mind the evolution of the relationship between men and wildlife, an analysis of the principle enables one to apprehend critically the way human societies make use of nature. Born of the collective realization of the fading of wildlife resources and the necessity of regulating the activities responsible for the destruction of species, the principle of rational use reveals, on one hand, its importance and, on the other hand, its limits and inadequacies when it comes to exploiting efficiently wildlife and considering more globally the protection of the biosphere. Whereas the prevailing economic logic is called into question, wildlife, when it is regarded as an underrated and overexploited natural resource, must be reconsidered in an ecological rationality. The thought of wildlife being a mere economic resource seems to be outmoded. The principle of rational use must develop around an "enriched vision" of wildlife, likely to make use of all its potentialities, while securing its preservation in the long term. Reappraised in an order within which values are not only economic any more, wildlife can be part of a model for "sustainable" development for the environment. Thus, the fact that countries which work with the international community, enforce principles of action, which aim at finding a new balance between men and nature, contributing to the construction of a new ecologic order which acknowledges the intrinsic value of natural elements without abandoning a humanistic conception

Full textIn the current context of biodiversity erosion, understanding processes controlling spatial and temporal distribution of diversity is a major challenge if we are to evaluate the impact of anthropogenic factors and propose efficient conservation policies. In this thesis, I focused on identifying mechanisms controlling different biodiversity components (populations and communities, taxonomic and functional diversity), using various tools to quantify biodiversity. The two aims were to: (1) improve our understanding of the relative impact of deterministic and stochastic processes in community assembly and (2) propose conservation strategies for two types of areas: protected areas (Iroise sea) and wider countryside (highway verges). My results show contrasted diversity patterns, depending whether the focus is on taxonomic or functional diversity (e. G. Specific richness vs. Species specialisation), or depending upon the taxonomic group (e. G. Plants vs. Spiders). Those results have direct implications in identifying underlying mechanisms but also in terms of conservation. I show that, while highway verges (ponds and embankment) can play a functional part in maintaining biodiversity, this part mainly depends upon management choices enhancing spatial biodiversity within those areas (e. G. Planting hedges). Finally, my results highlight the importance of taking into account the dynamic aspects of biodiversity to finetune management advices. In protected natural areas (Iroise sea), we have observed an impact of human activities on biodiversity (tourism, abandonment of farmlands) that can work against conservation objectives. However, we show that some management practices (concerted management of tourism, eradication of introduced species) can enhance the maintenance of protected species and ecosystems

Full textThe abundance of rare and small species is a characteristic of biodiversity, and these species are the least known. Moreover, ca. 1. 75 million species are known, but the global magnitude of biodiversity is probably over 10 million species, maybe many more. Last but not least, we are experiencing a major extinction crisis. Documenting biodiversity is thus a priority, if only to preserve it. Taxonomists are responsible for this documentation, as these are the ones who discover and describe species, but they suffer from a lack of manpower and infrastructure. Considering these facts (lack of knowledge on biodiversity, extinction crisis, taxonomic impediment), we examine the role taxonomists could play in conservation. The core of taxonomical work is double: discriminating species, and naming them. Discriminating species, before naming, gives data on species richness, rarity and size patterns, and could help the choice of conservation areas. When species are named, assessing endemism and threat status is possible, which also allows to orientate conservation actions. We illustrate these contributions to conservation with papers presenting results of terrestrial mollusc inventories in Gabon and French Polynesia. We then analyze the Fauna Europaea database, compiled by taxonomists, which shows that the indicators usually used to measure the state of biodiversity are missing most species and give a partial image of the situation. This thesis ends with an assessment of the interest and possibility of having a French scientific nomenclature for the molluscs of France, to facilitate conservation of poorly-known threatened species. Only taxonomists can deliver data on specific richness and patterns of endemism for the most numerous and least known species. Their contribution allows to take into account all biodiversity, and not only large vertebrates and flowering plants. In this framework, their role is crucial in conservation biology, together with population biologists, geneticists and ecologists

Full textThe goal of that study is to demonstrate that the substructures of the concept of sustainable development have been part of history and that two centuries of economic development have given birth to that notion, which has just emerged following the people's awareness of the existence of questionable means of development. The present social and economic concerns which set up the notion of sustainable development originate from the questioning of those who fathered the economic doctrine. We have then steered our analysis around to the genealogical recording of the sustainable development, and around to the consequences that sorne economic theories generate in terms of moral questioning. The chosen theories number five : Growth and development, in other words the emergence of the concept ofsustainable development, by taking the human aspect into account (chapter one) The place of social relations, or social transformation in the chain of history (chapter two). The strength of demographic constraints, that is to say the understanding of the importance of the population, which is in the heart of the worries concerning sustainable development (chapter three). The place granted to natural resources, that is to say the analysis of the relation to nature among the economists (chapter four). The environmental question, which amounts to asking the question: how to hold an arguable position in the relation between environment and economy ? (chapter five). And finally, the last chapter (chapter six) will be dedicated to environmental, social and economic issues, applying a concept, sustainable tourism, as an element of measure

Full textIn Northern Australia, a new category of Indigenous social actors emerged in the 1990s: “rangers”. Their jobs and programmes are based on the professionalization and formalization of “traditional” responsibilities for the land and sea. They are presented as natural resource management and biodiversity conservation mechanisms controlled by Indigenous communities and as a basis for local “development”.This thesis proposes a critical view of the ranger system, starting from the following question: is this system a form of “ecological imperialism”? The ethnography (2009-2010) of the social interactions at work in the activities of the Ngukurr community's ranger group (Arnhem Land, Northern Territory) is combined with a contextualization and an analysis linking local, regional and national levels with the international discourse.The ranger system reflects various endogenous and exogenous logics that go beyond its stated aims of environmental and socioeconomic resilience. It is based on complex power relations and negotiations between the different actors involved (including the Australian State), between “traditional ecological knowledge” and science, and between local and bureaucratic social relationships. This study reveals the bureaucratization process and the many external interventions and ambivalences inherent in this system which (re)produces social distinctions and tensions. It also highlights the mediator or broker role played by the rangers as well as the ambiguous position of the researcher in such a context

Full textBiodiversity provides lots of ecosystem services doing of its management a crucial issue. In situ conservation allows the continuous adaptation of populations to global changes. Subsistence farming Systems carry out this type of management maintaining a high level of agrobiodiversity thanks to seed exchanges among farmers. Such functioning reappears in industrialized countries. These types of Systems could expand their role in the landscape of the conservation of genetic resources. This interdisciplinary project at the interface between population genetics and ethnology sought to evaluate the relevance of such a model, characterizing the structure of the genetic and phenotypic diversity of population-varieties of bread wheat (Triticum aestivum) exchanged within a network of French farmers. The structure of these populations are simultaneously shaped by human action and environmental conditions; we identified and prioritized the impact of different evolutionary forces acting on this System. This study showed that : i) on-farm management of populations of wheat have a composite and complex genetic structure, which is important to take into account in management strategies; ii) the seed exchange networks submit populations to genetic drift, migration or selection in uneven ways depending on the context; iii) distributed and decentralized Systems have the emergent property of maintaining global diversity. Such social organizations are relevant to the management of agrobiodiversity because they allow the cultivated populations to maintain evolvability to rapid global changes

Full textThe promotion of the natural and cultural heritage is today an integral part of public policies enacted by both the state and local authorities. The stated objectives of these policies gather together a number of areas including the promotion of cultural heritage, along with the economic and territorial development of the regions in question. Once the interest, the objectives and the functions of the notion of promoting national heritage have been clearly defined it is possible to identify a set of rules and legal procedures which guarantee the actual substance of the aforementioned notion. The different features making up natural and cultural heritage have therefore come under the jurisdiction of property law. This French property law raises a number of questions centred on the economic reality of promoting national heritage. The idea of economic development outlined the French Code général de la propriété publique has also itself contributed to a debate on the matter of national heritage. Developments in environmental and cultural law have helped to shape the framework within which the promotion of national heritage is to be found. However, the aforementioned framework also includes a number of specific rules of a purely incentive nature. Promoting national and cultural heritage consequently provides an element of coherence and harmony regarding, on the one hand aspects of natural heritage, and on the other hand aspects of environmental, cultural and property law

They reflect the concept of nature, the social organization, cultural phenomena and elements of the techniques, notably linked to the national resources management and to the agricultural development. Diachronically, the Antique botanic advancement and more specifically the denominative and classificatory systems have known a internal evolution linked from the cognitive reflection of a primary gathering to a sorting increasingly organized in a hierarchy

After its recognition during the Rio Conference in 1992, the concept was took up by the international community and international organisations. In Europe, this approach was made concrete by the publication of a European strategy of ICZM in 2000 and by a Recommendation to the states members in 2002. Following the dedication of the ICZM concept by the french Government in 2001 and by the french Parliament in 2002, France prepare a national ICZM strategy since 2003. So certain instruments (SMVM, DTA, SDAGE, SAGE, bay contracts. . . ) fit partially in a prospect for ICZM, many efforts and legal adaptation still remain to make so that this concept is truly implemented in our country

Full textAlongside conventional methods of inventories, which require a high level of taxonomic expertise, several methods known as rapid measurement of biodiversity have been proposed. Among these methods, an acoustic method, designated as Rapid Acoustic Survey (RAS), was developed in 2008. The general objective of my thesis has been to provide a better definition of RAS approach from a methodological point of view, in order to evaluate the possible applications of RAS for estimating, tracking and analysing the spatial and temporal distribution of animal biodiversity. Acoustic indices have already been proposed which measure the overall entropy of the sound signal in an animal community and the acoustic dissimilarity among communities. The sensitivity of these indices to different causes of heterogeneity unrelated acoustic diversity was assessed (e. G. Ambient noise effect). The results show that the indices are not sensitive in the same way to the different causes of heterogeneity studied; the generated biased should thus be treated differently depending on the diversity index used. Once these methodological approaches have been treated, several applications of the RAS revealed the following points. In bird communities in Metropolitan, continental France, positive correlations between acoustic and phylogenetic diversity on the one hand and between acoustic and functional (reproduction traits and weight) diversity on the other hand have been identified. In New Caledonia, the level of micro-endemism is high which make the description of biodiversity difficult. The use of acoustic spectral dissimilarity measures highlight acoustic differences in three distant locations in the island with similar species richness and vegetation structure, but different in the composition of animal communities due to micro-endemism. This difference in multi-taxa animal communities is clearly revealed by the acoustic diversity analysis RAS. In India, two different managements of the coffee agroforest system are found, one using native species and the other one using an exotic species of shade trees. An acoustic survey highlighted differences in acoustic diversity and composition between the two managements revealing an impact of the use of exotic shade tree species on singing animal communities. The RAS method seems then a promising tool to assess local animal diversity even if some methodological issues should be considered to produce a reliable tool in several acoustic conditions

Full textThis thesis analyses the effect of the proximity of the actors in the economic valorization of the territories, the biodiversity and the patrimony, in a sustainable view. Moreover, we will analyze the role of the qualification of a biodiversity channel in the promotion of collective action dynamics, which underlies these strategies of territorial development. The results show that the management of the territory – by the means of tools for indication – could bring an elegant solution to the safeguarding of the biodiversity and socio-cultural and artisanal practices of the territories, while developing them on the market. Indication accounts to us for the relation existing between the productive system of the biodiversity channel and its territorial anchoring. The examination of the conditions of definition and mechanism installation of qualification adapted to the wild silk channel of Arivonimamo includes the “AOC” for the safeguard of the local practice, the “fair-trade labeling” for the improvement of the good being and the reduction of the poverty of the local actors and the silk- SPL at the rural District of Arivonimamo. Those local and private measures must be connected with a public political choice, for the sustainability of the mechanism. In addition, the requirements for the qualification of the wild silk products could be used as a basis for the step of qualification of the other biodiversity channels for Madagascar

The need for an adequate and coherent legal framework arises to resolve conflicts. The main issue is what kind of international regime on access and benefit-sharing is under formation

Full textIIn central Tunisia, the agricultural intensification of irrigated agriculture generates local and regional environmental impacts, linked to an increased consumption of inputs and resources, including water and soil. In favor of a more sustainable agriculture and in order to inform public policies of agricultural development, it is necessary to assess the impacts of agricultural practices and water and soil conservation planning (WSCP), and this at the territory scale. The question is how to implement an environmental assessment approach in a context of 1) scarcity of reliable data including statistics, and complexity of farming practices, 2) prominence of socio-economic issues over environmental concerns 3) lack of knowledge of the perception of local actors on these issues and therefore of difficulty in identifying relevant indicators (scientific and of the stakeholders) and mobilizable. We propose an innovative approach to design and implement a participative approach involving different types of actors, to enable them to get more insights into each other's logic and perceptions of the impacts of agricultural practices and WSCP. This approach is designed to produce quality information by valuing local knowledge, share and take into account the perceptions of different stakeholders, and finally, build a consensus to contribute to the development of more effective WSCP policies. This approach has been structured in two main stages: the design of a community of practices articulated to a participatory systemic rapid diagnosis and the implementation of participatory workshops. The evaluation mobilized a dual mechanism including external observers and a satisfaction survey among participants. The survey is based on an evaluation grid of this approach, its outcomes and its short term induced effect. Sharing and taking into account the information and data collected, as well as the expertise and perceptions of the various stakeholders, has made possible to produce information deemed satisfactory or very satisfactory by all the participants. This nourished the knowledge of almost all the stakeholders and contributed to a constructive dynamic of collective learning. Our approach has contributed significantly to the evolution of perceptions and to a stronger mutual understanding between government officials and farmers. A dashboard grouping the indicators mobilized by each stakeholder was discussed and allowed to highlight convergences and differences in their analysis grids. The gradual and adaptive structuring of the approach, the choices of the stakeholders, the venues for the workshops and the use of a neutral facilitator were very important factors for the commitment and the mobilization of the stakeholders, in particular at the central scale, in this operational space for consultation on territorial issues, agricultural practices and WSCP. This work demonstrates the interest of integrating the engineering of consultation and environmental assessment within one approach and its feasibility in a difficult context for the ACES policies implementation

Full textFrance must assess the state of conservation of its natural habitats in reply to Directive Habitats. We therefore looked at the impact of pressures such as channelization, on physico-chemistry and on 3 communities (birds, plants, invertebrates) of the habitat EU 3260, or “Streams with Water Crowfoot”. 17 reaches (6 control/11 channelized) in 4 rivers, were monitored seasonally in 2006-07. Channelization led to physical changes of the habitat in several spatial scales: reach, riffle-pool sequence, and microhabitat. For the 3 communities, richness was lower in channelized reaches than in control reaches. Dominant taxa were ubiquitous and resistant. Plants was an informative community because they reacted to the 3 spatial scales. Adaptive strategies of plant taxa were more diverse in channelized reaches due to the modifications of the dynamic of the EU 3260 habitat. Our study clears tools and measurements of management to preserve the state of conservation of the habitat EU 3260
Grenier, Christophe. "Réseaux contre nature : conservation, tourisme et migrations aux îles Galapagos (Équateur)." Paris 1, 1996. http://www.theses.fr/1996PA010685.
Full textThe Darwinian theory explains Galapagos nature peculiarity, whose islands were used along history as an open space by foreigners. Ecuador strengthened its sovereignty on the archipielago thanks to international laws, but the creation of a national park led to a process of destruction of galapagos singularity. For once nature was valued by a mediatic conservation policy, tourism networks could link galapagos to the world : today, islands nature is sold as a show for hurried visitors, and national park management ensures the profitability of the network tourism enterprises, most of them coming from abroad. Galapagos being a new province of Ecuador, the governments of the 1970' and the 1980' developed the islands economy. But the actual policy aims to reduce the insular touristic supply and thus the attraction of this booming market for the ecuadorians immigrants, because the fast growth of Galapagos population is dangerous while an increasing part of the archipielago conservation relies on funds provided by "ecotourism". The loss of insular patterns in the landscapes as in the way of life of the population is a strong process in the four inhabited islands as in the national park : the population is becoming poorer because it is kept off tourism economy, and a growing part of the islanders relying on export fisheries jobs reject conservation. Though the elaboration of many management plans, conservationnist organisations have little means, so numerous and profitable lootings take place in the national park. This failure is also nature conservation's one : only a geodiversity preservation policy, disconnecting galapagos from some networks, could stop the continentalisation of the islands and save their ecological and human characteristics

Full textAfter its independence, Algeria was confronted with a situation of very advanced degradation characterized by a significant regression of plant place setting an intensification of the erosive phenomena of the mountainous zones and the appearance of the landscapes become depopulated in the steppe. This situation is the outcome of a set of historic and natural factors. Considering the vital importance of the national heritage and its biological variety, Algeria leads a steady policy of development of the forest sector which was characterized through the various national plans and special programs. This thesis suggests detecting the elements which made failed this policy, to plan to recommend better one management of the Algerian forest and to determine the existing links between natural resources, rural population and development policy. A series of qualitative investigations on the basis of a guide of interview was made with the agents who participate in the elaboration of the forest politics and its implementation and the rural population to be able to loosen the failures connected to this last one. This present document redraws the product in which we ended in the term of our work on the ground, however and after a presentation of the frame and our problem, said document includes three essential parts: situation of the forest sector in Algeria, situation of the forest sector in Algeria, the Program of Rural Employment for the long-lasting management of the resources

Full textL'objectif de notre étude est de mener une réflexion sur les problèmes rencontrés par les gestionnaires d’une aire protégée dans la mise en œuvre de la stratégie de conservation par zonage.
Nous avons d'abord travaillé sur l’identification des modes d'appropriation et de gestion des terres, avant et après l'implantation de l'aire protégée. Nous avons procédé à l’analyse des modalités de prise en compte des structures endogènes dans la mise en œuvre des stratégies de conservation appliquées. Pour ce faire, nous avons mené des entretiens avec des personnes ressources, des acteurs au sein des populations locales, des personnes choisies en fonction de la représentativité qu’elles incarnent. Les résultats de ces entretiens ont été couplés aux relevés de terrain réalisés dans le but de cartographier les parcours de déplacement des populations en identifiant les éléments humains d'occupation de l'espace.
Nous avons ainsi identifié et cartographié l'état de la réserve de Luki en termes de surfaces exploitées avant et après l'implantation de l'aire protégée. Ce travail nous a conduit à découvrir les inconforts fonciers subis par les populations lors de l'implantation de l'aire protégée. Des situations d’inconfort le plus souvent ignorées par les acteurs de conservation.
Après l’étude sur les modes d'appropriation et de gestion des terres, l’analyse des modalités de prise en compte des structures endogènes et la cartographie des espaces exploités, nous avons poursuivi la recherche par l’examen des effets du zonage sur le développement et sur la conservation. L'évaluation des effets du zonage sur le développement a été faite sur base des données socio-économiques relatives aux activités introduites par les projets. L'évaluation des effets du zonage sur la conservation a été faite grâce au logiciel Envi 4.6, par l'analyse de trois images satellites. Ces observations ont été mises en parallèle avec les résultats des entretiens et des enquêtes par questionnaires effectués auprès des populations de la réserve. Les entretiens ont porté sur la carbonisation du bois et sur la chasse du gibier, deux activités que nous avons jugées destructrices de la réserve.
Les résultats de nos enquêtes montrent que les structures endogènes de gestion de la terre n’ont pas été impliquées, ni dans la création de la réserve, ni dans la mise en œuvre du zonage. Il existe pourtant un comité de concertation avec un représentant de la population, mais celui-ci n’est pas représentatif de l’ensemble des lignages. Les éléments qui caractérisent l’occupation de l’espace par les populations avant la création de la réserve n’ont pas non plus été pris en compte. Dans un tel contexte, les objectifs de conservation sont difficiles atteints à cause du manque d’appropriation du zonage par les acteurs locaux. Le zonage est motivé par la conservation et la conformité au modèle de réserve de la biosphère, le souci de développement socioéconomique restant secondaire. Le premier zonage réalisé en 1937 a initié des pratiques de gestion favorables à la conservation forestière, mais les effets socioéconomiques qui en ont découlé, ont contribué à accélérer la dégradation de la forêt. Le nouveau zonage effectué en 2004 n’a pas davantage permis de maîtriser la dégradation qui s’accélère encore.
L’étude débouche sur de suggestions permettant aux aménagistes de prendre en compte les besoins des populations locales avant tout intervention d'aménagement.

Full textThanks to its overseas collectivities, France enhances its heritage with a great diversity of species and ecosystems, often rare and sometimes unique. However, there are rather serious threats which weigh on this exceptional heritage. In this context, it is essential to evaluate the accuracy of the law of nature protection and biodiversity. The characteristics and legal status of the protection of nature, as well as its influence on the environmental, overseas and public laws, have been analyzed here. It will be shown that in contact with collectivities’ legal diversity – and a fortiori since the 28 March 2003 revision of the Constitution related to the decentralized organization of the Republic – a specific law on nature’s conservation is emerging. However, the efficiency of the overseas law, whether it is an exact copy of the law in Continental France or elaborated in a more autonomous way, still remains limited for the protection of biodiversity. It therefore appears necessary to strengthen the law on nature protection, both in its conception and enforcement. In this respect, an increase in awareness of certain ecological overseas’ specificities (such as being an island, extreme sensitivity to exotic invasive species, coral reef and endemic species, etc. ) could effectively contribute to this reinforcement
