ORBi Open Repository and Bibliography (207,634 recursos)
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

1. Niche modeling within and between species in the genus Erythrophleum : intergating phylogenetic data and environmental niche models to explore speciation mechanisms - Gorel, Anaïs
In this study we investigated the climatic niche between and within closely related tropical tree species of the Erythrophleum genus (Fabaceae, Caesalpinioideae): E. ivorense, E. suaveolens and E. africanum. Two major hypotheses, the refuge theory and the ecological gradient hypothesis, have been developed to explain the current distribution of tree clades across tropical Africa. To identify the speciation mechanisms, we used a combination of geographic data and environmental factors to quantify the degree of niche conservatism (or divergence). We used two sets of distribution data for the purpose of this study. Species distribution data for the whole of tropical Africa...

2. Family farming in a changing landscape : how activities change when forest disappears - Feintrenie, Laurène; Gillet, Pauline; Garcia, Claude; Boulaud, A. L.; Ferlay, A.; Codina Llavinia, Elisabeth; Lehnebach, Charlotte; Vermeulen, Cédric
In the Congo Basin forests, local communities used to live from hunting, fishing and gathering, and from slash and burn agriculture. Nowadays, few places remain isolated from the external world, and local practices often have to integrate new parameters. How do family farming and forest activities evolve in a changing landscape, when forest disappears? To answer this question we selected three social and ecological systems positioned in specific places on the forest transition curve (Mather 1992), to constitute a synchronic sample of forested social and ecological system representative of the evolution of Congo Basin Forests. We conducted in 2013 and...

12. Approche agroforestière. Synthèse des travaux menés par le projet DACEFI2 en agroforesterie. Document de capitalisation. - Boldrini, Sylvie; Meunier, Quentin; Boukouendji, Basile; Ibinga Bouka, Sostène; Federspiel, Michèle; Doucet, Jean-Louis
Le projet DACEFI-2 a eu pour mission première la promotion de la foresterie communautaire comme outil de développement des communautés rurales. L’approche au Gabon en matière de gestion des terroirs villageois s’est voulue plus embrassante, promouvant en sus de l’exploitation forestière des activités comme l’agriculture, le maraîchage, la collecte des produits forestiers non ligneux ou encore l’agroforesterie. L’agroforesterie est une thématique qui converge parfaitement avec la gestion raisonnée de la forêt, et idéalement avec les modes d’interaction préexistants des villageois avec celle-ci. Concilier dans un même espace la culture de plantes vivrières et l’accès à des arbres à fort intérêt socio-économique...

17. Pathways of change in a coastal resource system: Study from Kampong Trach district, Kampot province - Voe, Pisidh; Touch, Panha; Diepart, Jean-Christophe
Over the past several years, Cambodia’s coastal resources system has undergone considerable transformation. The causes have included uncontrolled fishing activities, tourism development, salt and shrimp farming, sand mining, and trade, to name just the most significant. Against this background, this study analyzes pathways of change over the past 15 years in coastal resource systems in two neighboring communities in the Kampong Trach district of Kampot province. The analysis proceeds on two different levels. We first look at change in respect of the cross-scale multiple drivers in the resource system at village level and its effects on the social and ecological components of the marine, intertidal and agricultural areas...
