I had the privilege of growing up in a country rich in cultural and biological diversity: Mexico. By the time I was done with highschool and had to decide what to do in life, understanding and preserving nature and culture had become my passion. My passion eventually became my work as well. 

Career

I hold a B.Sc degree in Environmental and Resource Management from Brandenburg University and a M.Sc. degree in Ecological Agriculture from the University of Kassel, in Germany. My professional and academic experiences comprehend a wide range of approaches and biocultural settings. I have worked in conservation and development projects tackling the utilization of non-timber forest products, rangeland management, and agriculture in Yemen and Liberia from 2008 to 2010. My previous research experience includes monitoring bird populations in Khao Luang National Park, southern Thailand. I have also conducted a systematic review of the agro-pastoral land use systems in the Hawf Protected Area, Yemen. The work that I currently do is a study with a strong component of ethnobotany and traditional natural resource appropriation (particularly plants) in Benin and Gabon.

Plants used in traditional spiritual practices in Benin and Gabon 

Commonly, scientists tend to group African traditional spiritual values and the rites that are related to their practice into the “obscure” and metaphysical science. This attitude does not only overlook an important aspect of societal life in Africa, but fails to acknowledge the interrelatedness of traditional religious beliefs to the concepts of health, the human psyche, and the natural environment. Because plants do not only play an overriding role in African traditional medicine but also in spiritual practices, understanding their use in this context poses a great potential to contribute to an improved plant resource management and, ultimately, conservation.

In my work, I document the use of plants for traditional spiritual practices of the Ewe-Fon in Benin and the Bantu-Kikongo in Gabon and, where possible, I try to provide scientific explanations for them. Although not an ancestral tribal group of enslaved Africans, the plant use of the Babongo of Gabon is also be studied as their belief-system and the associated plant use has evolved in close coexistence with Bantu-Kikongo tribes. Of special interest are the methods used for the harvesting and preparation of plants used by all of these groups, as well as their domestication and threat status; the crops grown for the veneration of their gods and spirits; and the ecological knowledge embedded in their spiritual beliefs.

Fieldwork including quantitative market surveys, plant collection and herbarium identification, cultural domain analyses, participant observations, and interviews have been carried out for six months in each of these two countries. The results obtained are presented with the ntention to inform decisions pertaining culturally appropriate development interventions and, eventually, to contribute to the conservation of valuable medicinal plant species and their ecosystems.

Traditional healer pays his respect to the iroko tree (Milicia excelsa), the king of the forest, before collecting medicinal plants in a sacred forest in Porto Novo, Benin.

Statues of the twins, a pair of vodoun spirits, surrounded by fruits and seeds of endangered species such as Caesalpinia bonduc, Tetrapleura tetraptera, and Afzelia africana. Other species not seen in the picture include Schrebera arborea, Ensette livinsgtonianum, and Xylopia aethiopica. They are sold at almost every market in Benin, as they are common ingredients in medicinal plant preparations and rituals. These plants are often found cultivated in home gardens of traditional health practitioners and soothsayers.
