Natural resources are taken in the nature for, in the most of cases to improve the conditions of existence of the population. In Sub-Saharan Africa, economics are often dominated by the exploitation of these natural resources which contribute to the formation of the national wealth. This exploitation of natural resources should thus allow the improvement of the welfare of the present generations without compromising the possibility for the future generations to improve theirs. So natural resources should be exploited so that the heritage represented by the environment is not altered and so that the populations living thanks to these naturalresources see theirs conditions of existence improving today and in the future.The sustainable development is thus the way which must to guide the strategies ofdevelopment in Sub-Saharan economics which are generously endowed in natural resources. This one dresses a triple dimension, namely economic, social and ecological. It is thus important to examine the relation between natural resources and sustainable development because, indeed natural resources have to allow the populations to know a sustainable development. If certain countries indeed, although provided in natural resources did not bring, on examination of the indicators of development which are at the lowest, elements of sustainable development in the past and today, it is important to reverse the trend. It is as such that the strategies must be mobilized in Sub-Saharan Africa. The examination of the case of certain countries generously endowed in natural resources shows that these should be a source of endogenous growth to envisage a sustainabledevelopment. From then on the good governance, the best distribution of receipts stemming from natural resources and the contribution of the foreign partners are important. The European Union as partner and financer has a role so that the economics of Africa in the south of Sahara put themselves on the path of the sustainable development from their asset which lies in ...

The main objective of this research is to show how the abundance of natural re-sources creates economic and political dysfunctions as ilustrated by African countries. This study is based on four essays. The first essay examines empirically about 36 African countries, the determinants of longevity in power. The second essay analyzes the effect of fragmentation in 45 African countries, with particular emphasis on political stability. The third essay deals with the effect of border disputes by conducting an empirical study of the DRC and its nine neigh-boring countries. Finally, the fourth essay focuses on the macroeconomic effects of the type of political regime in the DRC. We use several types of econometrics and data sources adapted to each of the situations mentioned. We achieve the following key results: (1) dependence on oil and minerals positively impacts longevity in power in Africa, and human capital reduces the chances for an African head of state to stay long in power. (2) fragmentation negatively impacts political stability. (3) the mining resource rents increase border conflicts in the DRC (4) The consequences of the type of political regime and the abundance of natural resources increase the macroeconomic instability in the DRC.We suggest that the promotion of the education sec-tor should be at the heart of government strategies and therefore a priority and the strengthe-ning of constitutional rules regarding elections. ; L'objectif principal de cette recherche est de montrer comment l'abondance des ressources naturelles crée des dysfonctionnements économique et politique à partir de quelques exemples de pays africains.

Le deuxième essai analyse l'effet de la fragmentation dans 45 pays africains, en mettant un accent particu-lier sur la stabilité politique. Le troisième essai traite l'effet des conflits frontaliers en menant une étude empirique sur ...
Up to the turn of the 18th century, forest resources in Sweden were mainly exploited in the southern part of the country. A rationalisation programme was established at a very early stage and Sweden entered the era of silviculture by placing trees at the centre of the nation's economic system. The favourable economic climate led to silvicultural activities moving northwards, where large forests were logged right from the early 19th century and their products sold on the international market under the supervision of shrewd businessmen that belonged to prominent merchant families. ; Ayant principalement exploité la ressource forestière dans sa partie méridionale jusqu'à la charnière du XIXe siècle, la Suède met très tôt en place une politique de rationalisation et entre de fait dans l'ère de la sylviculture plaçant l'arbre au coeur du système économique national. La conjoncture internationale favorable engendre une translation des activités sylvicoles depuis le Sud du pays vers le Nord où les grandes forêts sont exploitées dès le début du XIXe siècle pour le marché international sous le contrôle d'hommes d'affaires avisés issus des grandes familles commerçantes.

published in Raimond C., Zakinet D., Abdouramane M., Sylvestre F. (dir), Cross-searches on Chadian lacustres ecosystems. Before the Boko Haram insurgency, the economic dynamism of multi-use of space was based, in Cameroon's part of Lake Chad, on an effective and fair form of joint governance of natural resources, characterised by the great fluidity of coordination between users and the absence of groups of rights holders able to exclude other users from access to resources. However, the sustainability of this form of governance was challenged by local power games open with democratisation, which undermined the ability to act collectively. In lake territories which have largely been emptied of their populations since the insurgency, the 'return to development' directly affects the political dimension of the governance of natural resources. ; Before the Boko Haram uprising, the economic vitalityof the multi-use of space in the Cameroonian part of Lake Chad was based on an efficient and equitable mode of governance of the common property resources. This mode of governance was characterized by the fluidity of coordinations between users and by the absence of rights holders in capacity to exclude other groups from resources access. Nevertheless the sustainability of this mode of governance was called into questions by the local power games supplied by the democratization which undermined the collective action capacities. While the lacustrian territories have been emptied of populations, the "development recovery" gives rise to the political dimension of the natural resources governance. ; published in Raimond C., Zakinet D., Abdouramane M., Sylvestre F.

from an institutionalistic perspective, our article focuses on analysing ways of coordination between local actors for the sustainable management of natural resources. By mobilising the benefits of the local economy, we highlight how the dynamics of social relations can be activated to promote sustainable management of natural resources. More broadly, on the basis of a general reflection on the institutions for the common management of natural resources and the role played on them by the categories of proximity, we propose the elements for formalising the robustness of ecological social systems. We analyse the conditions under which a high degree of proximity can promote or, on the contrary, undermine the sustainability of an ecological and social system. This is illustrated by a concrete study case: the Mont-Bar Natura 2000 site (small forest area in auvergnat). ; S'inscrivant dans une perspective institutionnaliste, notre article porte sur l'analyse des modes de coordination entre acteurs locaux en vue d'une gestion durable des ressources naturelles. En mobilisant les apports de l'économie de la proximité, nous mettons en lumière la manière dont les dynamiques de relations sociales peuvent être activées pour favoriser des pratiques de gestion durable des ressources naturelles. Plus largement, à partir d'une réflexion générale sur les institutions de gestion commune des ressources naturelles et le rôle que jouent sur elles les catégories de la proximité, nous proposons les éléments d'une formalisation de la robustesse des systèmes sociaux écologiques. Nous analysons sous quelles conditions un degré élevé de proximité peut favoriser ou, au contraire, nuire à la pérennité d'un système écologique et social. Notre propos est illustré par un cas d'étude concret : le site Natura 2000 du Mont-Bar (petit territoire forestier auvergnat).
In this thesis, we propose to the scientific community an alternative method of analysis from the interactions and cognition coming from the management of natural resources. The created system is called SIEGMAS (Stakeholders Interactions in Environmental Governance by a Multi-Agent System). It's a Help tool to the decision on the simulation of interactions between stakeholders acting on a territory in the Common-pool resources via an environmental, social and economic interface. The aim of the SIEGMAS is double. on the one hand, It is a matter of giving a generic, model agent re-usable dedicated to the scientific community for the management of natural resources. On the other hand, the aim consists on giving a framework of computer solution adapted to the decision-makers of politic and economic area for the decision making. ; Dans cette thèse nous proposons à la communauté scientifique une méthode alternative d'analyse des interactions et de la cognition découlant de la gestion des ressources naturelles.

The Lake Chad is unique in the Sahelian band. Whereas large scale irrigated schemes has characterized the other wetlands, here the development of agriculture, cattle breeding and fishing has been based on the use of the water floods and on mobilities. Almost virgin until the 1940s, the Lake has become a highly populated and cosmopolitan area, exporting diversified foodstuffs to the urban markets of the sub-region. Through the analysis of agrarian and territorial dynamics of the Cameroonian lake shores, this research questions to which extent multi-use of the natural resources and mobilities may allow further agricultural intensification and population increase in such an uncertain environment.Closer complementarity and synergy between activities pave the way for ecological intensification and territorial development inducing wealth and job generation. Due to its marginal nature, the Cameroonian part of the Lake has been the place of continuous social innovations, ensuring to a great diversity of people the access to productive assets and markets. In this sense, it has been actually decisive for the dynamic of intensification. Hydro-ecological, economic and demographic uncertainty has been integrated into the "normal" functioning of the agrarian system and territory. Nowadays, the political uncertainty threatens the future of the Lake Chad. It results both from agricultural and environmental policies and from conflicts between local authorities, that are constitutives of the relation between the State and the populations. ; Le lac Tchad étonne par sa singularité.

À travers l'analyse des dynamiques agraires et territoriales de la fenêtre lacustre camerounaise, ce travail interroge les opportunités qu'offrent, dans un environnement incertain, le multiusage des ressources et les mobilités à l'intensification des processus productifs et à la densification démographique.Le renforcement des complémentarités et synergies entre activités dégage les voies d'une intensification écologique du mode d'exploitation et d'un développement territorial, créateurs de richesse et d'emplois. En favorisant l'émergence de rapports sociaux et d'institutions innovantes assurant l'accès aux ressources productives et aux marchés à une grande diversité de populations, le statut de marge territoriale de la fenêtre lacustre a été déterminant dans la dynamique d'intensification. L'incertitude hydro-écologique, économique et démographique a été intégrée au fonctionnement « normal » du système agraire et à celui de territoires qui se singularisent par leur mobilité. Aujourd'hui, c'est l'incertitude politique qui menace l'avenir du lac Tchad. Elle résulte des conflits de pouvoirs locaux constitutifs du rapport de l'État aux populations, et de l'action publique à travers les politiques agricoles et environnementales.
