Introduction
I am Professor of Forestry (silviculture, forest ecology and management, forest dynamics) at the university of Abomey-Calavi (Benin, West Africa). Actually, I am leading a research team on forest dynamics, forest biodiversity, plant sociology, and biodiversity informatics so as to contribute to the sustainable management of natural resources in the context of global change.

Empirical data reporting forest pest damage on Khaya senegalensis have raised concerns over their potential economic impacts. Although the problem was also reported in Benin, scientific data on their economic impact on plantations are lacking. In this study, we combined dendrometry and survey data to estimate the economic impact of wood damage caus...

The impact of anthropogenic activities on the spatiotemporal dynamics of the forest of Dogo-Kétou has been studied in relation to climate change observed in southeastern Benin. Especially, this study has detected the changes in climate parameters in southeast Benin from 1954 to 2016 and in forestland use from 1986 to 2018. A climatic break was dete...

The “Trois Rivières” natural forest reserves is one of the largest and strongly threatened rainforest ecosystems in Benin. That is mainly caused by extensive agriculture, which is mostly practised by smallholder farmers, aggravated by yields dropping linked to climate change. This research aims at analysing ecological practices that will enable sma...
