Understanding local knowledge about wild edible plants (WEP) is essential for assessing plant services, reducing the risks of knowledge extinction, recognizing the rights of local communities, and improving biodiversity conservation efforts. However, the knowledge of specific groups such as women or children tends to be under-represented in local e...

introduced species. The associated agrobiodiversity, including plants that grow spontaneously and are protected or tolerated by farmers, is composed of a mix of native and introduced species. This situation, which is paradoxical for an island with a very high level of endemicity is the result of a double process of species introduction. The first i...

Background Understanding the perceptions, preferences and management practices associated with intraspecific variability of emblematic African tree crops is critical for their sustainable management. In this paper, we examine how the agrobiodiversity of a fruit tree species native to Central Africa, the African plum tree (Dacryodes edulis), is perc...

Current climate change is responsible for the greatest food scarcity ever known in the extreme south of Madagascar. Knowledge of wild edible plants has never been so crucial in this area to limit the food risk. Consequently, there is an urgent need to document this knowledge. However, the knowledge of specific groups such as women or children tends...

1. Interactions between farmers and agrobiodiversity are key drivers of agroeco-systems sustainability and of the resilience of such systems to perturbations, but research into the human/nature interactions have overlooked some important aspects of agrobiodiversity management. In particular, farmers' ecological knowledge of the spatial organisation...

Cocoa is a major crop and income source for most farmers and rural households in the Centre, South and South-West regions of Cameroon, where cocoa is generally produced in agroforestry systems. In this country, cocoa-based agroforestry systems (CBAFS) are undergoing multiple changes alongside the rapid changes underway in the natural, economic and...

Understanding how biocultural landscapes, as a result of human-nature interactions, have emerged and will evolve seem to us a fundamental pre-requisite to better anticipate and understand the new ecological dynamics at work in Madagascar. This may help to better implement biodiversity conservation measures within and outside protected areas. In thi...

The local perception of climate change and the process that leads IPLCs to their adaptation strategy is still unknown. However, this is crucial to grasp local responses, stakes and predict future trends. To fill this gap, we worked with Betsileo peoples (Madagascar), a group of farmers deeply impacted by seasonal shifts. We adopted a holistic appro...

Trees are a traditional component of urban spaces where they provide ecosystem services critical to urban wellbeing. In the Tropics, urban trees' seed origins have rarely been characterized. Yet, understanding the social dynamics linked to tree planting is critical given their influence on the distribution of associated genetic diversity. This stud...

Malgré des mesures de protection, la forêt dense humide de l'Est malgache tend à se réduire à des fragments forestiers. Le processus de fragmentation n'est pas pris en compte dans les suivis de la déforestation par télédétection qui comparent le couvert forestier entre plusieurs dates ; la question est de savoir s'il est perçu par les populations r...

Beginning with an examination of the origins of the emergence of the ES concept in ecology, this chapter explores the different interpretations and uses of this concept, as well as the debates it has generated within the discipline. Indeed, for many specialists, ‘ecosystem services’ are not self-evident in ecology. As long as the concept served chi...

In Madagascar, biodiversity, local livelihoods and agroecosystems are increasingly threatened. It is critical to understand and support local social-ecological systems that sustain livelihoods and value biodiversity. This study investigates why Betsileo communities in Ambendrana and Sahabe protect isolated individuals and clusters of Ficus species...

Microsatellites were designed and characterized in the African fruit tree species Dacryodes edulis (Burseraceae). The fruits are commercialized throughout Central Africa and the species is present in forested environments as well as cultivated systems. The high variability of these markers makes them suitable to investigate the structure of genetic...

Children are often marginalized in research on local perceptions and values of the environment, and even more of marine spaces and species. Yet, as users and future managers of fisheries, they are directly concerned by issues related to their sustainability. Moreover, they not only receive, but also contribute to produce, hybridize, and circulate f...

Highly valued for its edible fruits, the safou tree, Dacryodes edulis, is a major component of farming systems in Central Africa. In Cameroon, the species has drawn much attention since the 1990s because of its market potential. Among other fruit tree species, safou trees are integrated within cocoa-coffee agroforests as a means of diversification....

Xerophytic thickets (XT) in south-western Madagascar are threatened by deforestation, mainly due to slash-andburn cultivation. However, few studies have been conducted on how XT ecosystems operate. This study characterizes XT plant biodiversity and analyses the post-cultivation regeneration process of XT on the Belomotse plateau. Sixty 10 m×10 m pl...

Dans les zones arides, les espèces végétales et les savoirs écologiques locaux qui leurs sont associés contribuent à la qualité de vie des populations. Ces savoirs écologiques améliorent la résilience des individus face aux changements environnementaux et socio-économiques, mais ils sont généralement inégalement répartis au sein d’une population do...

Environmental education for children is one of the fundamental tools required to reverse the degradation of our environment and the biodiversity erosion. Currently coral reefs are part of the vulnerable ecosystems which are most threatened by human activities and climate change. Responding to these pressures demands decisions at multiple scales, ba...

In order to understand the interactions between the intensification of safou tree cultivation, farmers’ cultivation practices and the varietal diversity, we hypothesized: - that strategies of intensification influence the cultivation practices - that strategies of intensification resulted in a change in varietal diversity.
