All Those Who Live under the Sky Are Woven Together like One Big Mat

Catching sight of the coast of Madagascar for the first time, Astrid Knoblauch was full of anticipation. Stepping onto Madagascar soil, Astrid Knoblauch takes in the song of the red fody birds and the vibration of a rusty Peugeot under foot. She is about to embark on an adventure that involves diving head-first into a new culture, getting bitten by a Fosa, and drones. Astrid talks to us about her inspiration for moving her life and work to Madagascar, what drone innovation means for the world of global health, and how with the right combination of perseverance, hard work and luck, technology has the capacity to greatly influence the lives of individuals, particularly in remote regions.

Madagascar, the fourth largest island in the world with 90% of its wildlife being found nowhere else on earth, has some unexpected innovation happening high above the baobab trees and vast rainforests. "There is something majestic and powerful about these Baobab trees," said Astrid Knoblauch, a Swiss scientist at Swiss TPH and a resident of Madagascar since 2017. "...but have you ever seen them from above?" Astrid has been working on the capability of drones to deliver TB diagnostic samples and drugs in rural areas of Madagascar. Not only do they give us a birds-eye view of the places in which we live and work, but they also have the capacity to fill existing gaps in healthcare.

Astrid, why Madagascar?

"It’s probably the question I was asked most… After my PhD, I was looking for an opportunity to work on a project from beginning to end, really being based at the scene of the event. One day, I walked into Marcel Tanner’s office – for a completely other reason – and asked, in passing, if he had a contact in Madagascar, upon which he replied “Send me your CV, I’m going there next week”. At the same time, I also heard through Swiss TPH colleagues, that a professor from Stony Brook University was looking for a postdoc on a drone project based in Madagascar. My supervisors and Swiss TPH at large have supported me throughout this professional journey, and I can only hope that my experiences gained here will benefit Swiss TPH in the future."

Tell us a bit about your work with drones.

The Drone Observed Therapy System (DrOTS) project used drone technology to gain access to some of the world's most inaccessible communities. The project, led by the Stony Brook University (New York, USA) and the Institut Pasteur de Madagascar, explored the use of drones in a rural district in Madagascar. The goal was to facilitate the transportation of medical supplies to remote villages, eliminating the need for patients to embark on the journey of multiple days through countless rice paddies and across rivers to the nearest health facility.

It was a journey with many ups and downs: when you receive a flight permit after a few months, you feel you’re taking off. When the drone starts producing smoke just at take-off, you’re disappointed, make sure you don’t lose your humour and you definitely push on. The tricky part was that at the time, drones that do bi-directional transport in such settings were yet to be developed and optimized. In the meantime, our project has come to an end but it found continuation with one of the major health service providers in Madagascar with funding from the Global Fund. This was the best possible outcome of our project.

What potential do drones pose for healthcare provision?

The use of drones for healthcare keep increasing and they can support in the supply chain, emergency response and disease prevention, as well as the deployment of networks for data harvesting in unconnected areas, or research. For us in particular, the goal was to bring the diagnosis and the care of TB closer to the patient. This is important because in Madagascar today, almost half of the cases are left undiagnosed and others are lost before or during treatment.

Is Madagascar as a country prepared for such technology? What barriers exist?

In order to be able to integrate drones or other technologies in to a health system, it needs to be assured that such a system can be maintained locally, meaning with local capacities and local markets. We were very pleased that the follow-on drone project funded by the Global Fund partnered with WeRobotics Flying Labs that is indeed implementing such an approach: building local skills and catalyze local businesses to establish a local system. This was actually one of our recommendations post-project and I believe with this approach and perseverance from local actors as well as funders, Madagascar can do it!

Drones aside: tell us a bit about your life in Madagascar.

I admit, I’m in love with Madagascar and the Malagasy people. It’s incredibly beautiful and diverse, you find lush rainforests, the high lands with its rice paddies, the most amazing beaches and blue waters, different types of mountain chains and much more, each with its own biodiversity and home to the native ethnic group. Even though I’m personally not working in the conservation sector, I believe that it is one of the most pressing issues, especially in Madagascar, also knowing that human and environmental health are closely interlinked.

One of my first missions upon arrival in Antananarivo was to look for a soccer team! Beyond soccer being my favorite sport, it’s a good mix of people from Madagascar and all over the world. The soccer team was also my entry door to a social life: there’s lots of concerts, local craft sales, game nights and trips organized all year round. As a known non-cook, I often enjoy the many charming and excellent restaurants in town which offer a mix between Malagasy, French and Asian cuisine, also with friends and Swiss TPH colleagues visiting from home.

Tell us a story about something extraordinary that has happened to you so far.

An experience that apparently not many people make in Madagascar is getting bitten by a Fosa. This endemic carnivore that looks like a mix between a cat and a dog is usually feeding off lemurs, but during a restaurant dinner with my visiting parents in the west of Madagascar, one animal maliciously attacked me from the back, leaving its teeth marks in my thigh – ouch!! It was to my advantage and that of many others, that Madagascar has implemented a rabies surveillance and vaccination network covering every region.

The visit in the next referral hospital for the post-exposure vaccinations was smooth although not without great astonishment and amusement to the health staff. I suppose, in that area, this incident is a sign of domestication of the animal. It shows that the human’s penetration of nature comes with health risks for both the animal and humans, COVID-19 being a prime example.

"The use of drones helps to provide patient-centric care to thousands of people, and may help in finding some of the missing millions of TB cases."

What other start-up projects are you currently working on? Any cross-linkages to your work with drones?

I’ve met so many impressive and inspiring people from across the world through my work with Swiss TPH over the past years. Milka and Kennedy are two of them, who create opportunities for themselves and their communities. This year, with both of them, I have jumped into the adventure of launching a start-up. With ifarm360 in Kenya, we’re linking global investors to smallholder farmers to promote livelihoods and food security. With Malio, we’re looking at managing the waste management system of Toliara, a town in south Madagascar, and its local industries. Both of these projects are rooted in public health and make use of modern technologies. Both sectors have already developed excellent use cases for drones, which we can explore once – and if – we’re on our feet.

The drone project has come to a close: what now?

As for the drones, long-term investments and implementation, in-country capacities and businesses are required to find and establish the technology's optimal fit into the health system in Madagascar and other countries. We have to continue to be a little creative to give everyone an equal opportunity to quality healthcare. As for me, the drone project was only the springboard for other TB control and research projects that we’ve tackled in Madagascar. We continue to use innovative technologies and leverage data to improve TB control. It continues being a very educational and valuable journey for me.
