On the Ground in Madagascar with Valerie Torti

Valerie Torti Valeria_Torti

Dr. Valeria Torti is a Postdoctoral Fellow at the Department of Life Sciences And Systems Biology at the University of Torino (Italy). For her master’s degree, she researched the songs of the Indri indri and in 2013 she received her PhD in Evolutionary Biology and Biodiversity Conservation from the University of Torino, after spending 11 months in the field in Madagascar. From that moment a common thread throughout Valeria’s research career has been joining her bioacoustics and ethological work with the biodiversity conservation issue.

Nowadays, her research focuses on non-invasive census techniques, based on vocal fingerprints, as a mechanism for monitoring vocalizing animals’ groups and lemur populations in the wild. Valeria was awarded grants from the CRT Foundation (Master dei Talenti della Società Civile), is a PCI fellow, and is a CO-PI for a Margot Marsh funded grant. She participated in writing several funded projects for conserving Malagasy wildlife, collaborating with different international organizations including GERP and Association Mitsinjo.

When did you first get interested in working with lemurs and conservation and what motivated you to undertake this work?

Valerie Torti Indri_IMG_0464After I started my studies in biology, I always assumed that I would eventually go to Africa and work on wildlife conservation, especially with primates. As it turns out, I ended up at the Ethology Lab at the University of Torino (Italy) where my interest for primates dramatically increased and improved, thanks to a bachelor’s thesis that involved vocal tract modeling in lemurs. After that, I did my master’s fieldwork in Madagascar and I became increasingly interested in what could be done to contribute to lemur conservation in the field. My under- and post-graduate experiences led me to pursue my interests, and I started soon after a PhD in Evolutionary Biology and Biodiversity Conservation. The main purpose of my work was to investigate vocal variation in Indri indri, a large-sized singing lemur inhabiting the rainforests of Madagascar. Although my project began primarily as a bio-acoustic project, I quickly expanded my scope and refocused my research to really have an impact on lemur conservation.

What projects are you currently working on that relate to lemur or environmental conservation?

Valerie Torti RainyDay_IMG_0259I currently work on a project that combines research and conservation together to achieve long-term conservation objectives in two eastern rainforest sites, Maromizaha NAP and Mitsinjo SF, in the Ankeniheny–Zahamena Corridor, in Madagascar. This program benefits from the contribution of multiple partners (e.g. UNITO, GERP, Association Mitsinjo, San Diego Zoo).

The focus of my research is still the indri (Indri indri), the largest living lemur. Due to its restricted geographic range and low population densities, the indri is listed as Endangered, and is considered one of the World’s 25 Most Endangered Primates. Improving the conservation outlook of the indri will require further knowledge about this species and its habitat. But we also need programs that will enhance education, awareness and will promote capacity building among the local people.

Finally, I am the distance-learning tutor to several PhD students from different Comorian and Malagasy Universities, in the frame of the EU ACP Edulink II EGALE Project (“Gathering Universities for Quality in Education”; Contract NFED/2012/320-117). This project aims to train qualified native human resources in the field of sustainable agriculture and food security.

Valerie Torti Equipment_IMG_0086What is a typical day like for you? What is your day like when you’re working in the field?

A typical day in the forest mirrors the daily indri routine! Which means, my day consists of getting up at about 4:30 – 5:00 AM (depending on the time of year), eating breakfast and packing survey equipment (audio and video recorders, microphones, GPS devices, two-way radios, etc.). We then try to find the animals by scanning their territories (indris live in family groups, actively defending their territories, so we do not use collars to follow them!) before their first morning song (these lemurs are known to emit loud long distance calls, “the song”, that can be heard at about 2 km).

Valerie Torti Students_IMG_0408Once a group is found, we follow the animals in their daily movements until they stop at their sleeping site. We gather as much data as possible before returning to the research station. After a refreshing shower in the river, we are ready for a delicious traditional Malagasy lunch and a quick nap. The afternoon at the camp is devoted to data organization and first elaboration: we look over samples, copy data from the devices to our computers, and organize photos, videos and audio recordings. At about 7:00 PM, we have dinner and then we discuss what we have collected during the day. After a short briefing to prepare for the next day’s activities, we call it a night and head to bed!

What are the hardest parts about working in Madagascar?

In my experience, the hardest part of the work is seeing that, even if we are obtaining results at a local level in building capacities and in educating people to be aware of the great potential of forests for their survival, stopping illegal deforestation and lemur hunting at a larger scale is difficult. Every year forest disturbance in Madagascar eastern rainforests doubles if compared to the previous year, and new traps and cages appear even in the protected areas. We need to be well aware that we are facing poverty while conserving biodiversity; local people’s primary concern is feeding their families, and conservation projects must take this into account. Projects should be designed with a bottom-up approach, and communities’ voices should be heard!

Valerie Torti Tavy_IMG_1129What are the biggest threats facing lemurs in your line of work, and what needs to be done to alleviate those threats?

The effectiveness of Protected Areas as a conservation tool depends on the ability to buffer plant and animal populations against anthropogenic forces (e.g., fires, deforestation, illegal logging, agriculture, etc.). In recent years, both Maromizaha and Mitsinjo SF faced the challenge of forest habitat loss, due to several factors affecting rural communities in the neighborhood (e.g., the need for charcoal, the request for new lands for farming and agriculture). As I mentioned above, we need to provide people with the capacities and the means for managing biodiversity in a sustainable way. Involving rural communities is an urgent task. Without their support conservation is just an ideal fight! I think that providing community with alternatives to forest illegal exploitation (e.g. alternative energy sources, eco-tourism, new agricultural practices, etc.) may allow us educating the public on how biodiversity is linked to human survival, and not just to species conservation. Another important aspect is, in my opinion, the involvement and training of women. In order to reach a result, women need to be educated on the values, management and sustainability of natural resources as alternative sources of livelihood.

What is the funniest or most memorable thing that has happened to you while working on lemur-related programs?

I have so many funny memories! Every experience in the field reminds me something that happened the year before with the guides, the students, or with the people working around the camp, and the greatest thing is that I can share those moments with the “Babakoto” Team (NB babakoto is the Malagasy name of the indri)! However, the biggest moment in the field happened when I got to meet Sir David Attenborough of BBC. He came to the neighborhood of Andasibe while the BBC ‘Madagascar’ documentary was being filmed. It was great to sit with him and chat about the indris’ song.

Valerie Torti Field_moments_IMG_1155In ten years, what do you hope to have accomplished in terms of your work in lemur conservation?

First of all, I hope I will continue working with the team to fight lemur hunting and habitat loss. I hope that community involvement through national and international Partnership will lead to a reduction of forest loss in both Maromizaha and Mitsinjo Forests. Regarding my research, I am quite confident that studying indris’ songs and other lemurs’ vocal repertoires will shed light about the demography, sociality, group-living and language evolution, and will provide important insights to develop non-invasive census techniques for wild vocal animals. I hope that our methods will contribute to a deeper understanding of how we can manage wildlife though community-based effective actions.

How can people across the world help save lemurs and help your work?

I think that everyone could contribute to lemurs’ survival by few simple, undemanding steps. Donations to non-profit organizations, especially local ones, are a fundamental means to finance actions in Madagascar. Several institutions across the world have “adopt-a-lemur” programs or other campaigns to raise funds. Another important step can be visiting zoos and supporting their in situ conservation programs. Moreover, choosing ecotourism over traditional vacation represents another important way to contribute to environment safeguard. Getting more particular to the activities I am involved with: donations to U Onlus or to GERP, volunteering in Madagascar or from home, students’ internships, and “adopt-a-lemur” campaigns. Another important aspect of my work is involving Malagasy collaborators in writing grant proposals or projects.
