Introduction
I am a biologist working as Associate Scientist in the Forest Genetic Resources for Resilient Landscape Team of the Alliance of Bioversity International and CIAT. My main research focuses on developing and implementing spatially explicit analysis methods (such as species distribution modeling, threat vulnerability mapping and ecogeographic diversity analysis) to support decision making on forest genetic resources and crop wild relatives conservation and restoration at intraspecific level.

Article
Full-text available
Over the last decades agroforestry parklands in Burkina Faso have come under increasing demographic as well as climatic pressures, which are threatening indigenous tree species that contribute substantially to income generation and nutrition in rural households. Analyzing the threats as well as the species vulnerability to them is fundamental for p...

Full-text available
Our spatial analysis framework aims to predict, at the population level, where multiple threats (overexploitation, overgrazing, landslides, fragmentation and predicted climate change), superimposed on patterns of genetic and nutritional diversity, are likely to have negative impact on important indigenous fruit and nut tree species.

The knowledge, conservation and use of plant genetic resources (PGR) has never been as important as now with the risk of climate change and habitat degradation threatening the very species that we depend upon. The challenges we face in food security range from the global to the local perspective; from the identification of global centres of crop di...

Ex situ conservation in genebanks is the most important way of conserving plant genetic resources for food and agriculture (PGRFA) (FAO 2010). The use of germplasm conserved in genebanks depends to a large extent on the quality and quantity of data available about each accession. Initial selection of accessions for use in research or breeding is of...

We consider how wild biodiversity (WBD), such as birds, insects and spiders, has been valued over time through both utilitarian and intrinsic lenses, and the implications this has had on conservation policy and practice. In doing this we reflect on the evolution in biological conservation theory in respect to valuing WBD and highlight how the recen...
