IUCN mourns the loss of leading conservationist Gustavo Fonseca

IUCN mourns the loss of leading conservationist Gustavo Fonseca, and wishes to honour his contributions to the Union and to global efforts to preserve nature.

In an illustrious career spanning more than 30 years, Gustavo was integral to IUCN; he served on the Steering Committee of the IUCN Species Survival Commission (SSC), was a member and former Chair of the IUCN SSC Anteater, Sloth and Armadillo Specialist Group, and a member of the IUCN World Commission on Protected Areas. He was also a long-standing and esteemed colleague as Director of Programs at the Global Environment Facility (GEF) with whom IUCN worked closely to further conservation science, policy and action around the world.

We send our deepest condolences to Gustavo’s family and friends. His colleagues at the GEF have published this tribute, which we encourage all to read; please also see this tribute from the Inclusive Conservation Initiative.

Those who knew him are also encouraged to post personal remembrances below. 

Russell A. Mittermeier, Chief Conservation Officer Re:wild and Chair, IUCN SSC Primate Specialist Group

In Memoriam: Gustavo Alberto Bouchardet Da Fonseca (1956 – 2022)

I was in Sinop in the northern part of the state of Mato Grosso on August 31, 2022, attending the 19th Congress of the Brazilian Primatological Society. It was a warm sunny morning, and we were having a really pleasant productive event. However, everything suddenly changed when I got an email message from my good friend Claude Gascon from the Global Environment Facility. He said it was urgent. I asked what it was, and he replied that he had to tell me in person and not via email. I quickly called, and had one of the biggest shocks of my life – Gustavo Fonseca, my great friend of nearly 40 years, had suddenly passed away in his sleep earlier that morning. I couldn’t believe it. How was that possible? He had just been at meetings the previous several days, and he seemed to be in vibrant good health and very actively engaged in his work as the Director of Programs at the Global Environment Facility where he had been a key figure for the past 15 years. But sadly, it was true. Gustavo, only 65, had left us. I am still trying to come to grips with this tragedy. It is almost incomprehensible.

For those of you who might not have known him as well as I did, Gustavo was a force of nature, a real leader, a world class biologist, and an astute politician. I first met him in 1983 at Fazenda Montes Claros, the famous research site for the northern muriqui monkey (Brachyteles hypoxanthus) in the Brazilian state of Minas Gerais.  Like me, Gustavo was a primatologist who had started out working on the black-pencilled marmoset (Callithrix penicillata) in the Brasilia area and was carrying out a short-term project on the muriqui. We immediately hit it off and began a friendship that lasted for the next four decades.  

Gustavo had a very long list of major accomplishments. Born in the state of Minas Gerais, he grew up in Brasilia at a time when Brazil’s new capital was being built. He studied Biology at the University of Brasilia, graduating in 1978, and then went to the University of Florida, Gainesville to do his Masters and PhD from 1982 and 1988. He specialised on the primates and small mammals of Brazil’s Atlantic Forest, one of the world’s highest priority biodiversity hotspots, and was instrumental in putting the Atlantic Forest on the international conservation map. After finishing his doctorate, he moved to the Federal University of Minas Gerais in Belo Horizonte, becoming a professor at the Department of Zoology in the Institute of Biological Sciences, working closely with another great pioneer, Prof. Celio Valle. Very quickly, he created a graduate programme there in Ecology, Management and Wildlife, in part modelled on the programme that he had been in at the University of Florida. This was the first course of its kind in Brazil. In part because of Gustavo, we based our WWF-funded work on the primates of the Atlantic Forest at the university in Belo Horizonte and worked closely with students there to carry out our programme over the decade of the 1980s. While in Minas Gerais, he also was instrumental in 1989 in the founding of the Fundação Biodiversitas, long one of the leading conservation NGOs in the country.

When I moved from WWF-US to become President of Conservation International (CI) in 1989, Gustavo was a strong ally in helping me to create a Brazil programme for that organisation, and a couple of years later I invited him to become the Executive Director of our programme there.  Under his leadership, it grew rapidly to become our largest field programme, and we later promoted him to lead our entire South America programme, overseeing activities throughout the continent.

Gustavo shared with me a love for the work of IUCN. During the 1990s and the early part of the 2000s, we served together on the Steering Committee of the Species Survival Commission, and he was a member of the World Commission on Protected Areas as well. He also was the first Chair of the SSC Anteater, Sloth and Armadillo Specialist Group, which was originally called the Edentate Specialist Group. 

In 1999, CI was awarded a very generous gift from Gordon Moore, co-founder of Intel and a CI board member, to create a new Center for Applied Biodiversity Science (CABS). CI’s CEO Peter Seligmann and I had a quick discussion about who might best lead this center, and we almost immediately settled on Gustavo as the obvious choice. Soon thereafter, he moved to Washington, DC and within the next few years turned CABS into one of the world’s leading organisations for conservation science, with a publication record comparable to or exceeding that of the best university programmes in the world. As if that weren’t enough, we also put him in charge of all conservation field programmes and science at CI, a real tribute to his intellect and his capacity.

In 2007, a great opportunity presented itself for Gustavo to move to the Global Environment Facility, one of the products of the great Rio 92 Earth Summit (which Gustavo himself had participated in) and the biggest funding mechanism in the world for biodiversity conservation. There he took on the role of Director of Programs, reporting to then CEO Monique Barbut. At the GEF, Gustavo transformed the organisation from a siloed funder of environmental projects separately focused on climate change, land degradation, and biodiversity, to a funder of integrated projects and programmes aimed at arresting the drivers of environmental degradation, and, in so doing, producing multiple benefits in protecting species and habitats, mitigating climate change by securing carbon in tropical forests, and creating landscapes where land and soil quality could sustain rich biodiversity as well as other productive uses. He occupied this key position under three GEF CEOs, most recently under our great friend Carlos Manuel Rodriguez from Costa Rica, and it was this position that Gustavo held at his untimely death on August 31.

Gustavo had hundreds of publications to his credit and a number of books, several of which we co-authored, and he received a number of prizes, among them the Rodolfo von Ihering Award from the Brazilian Mammalogical Society (1988), the Order of the Golden Ark from the Dutch Government (2001), the University of Florida’s Distinguished Alumnus Award, and the Florida Museum of Natural History’s Oliver Austin Award for outstanding research in the natural sciences.

I had the great privilege of working closely with Gustavo from the early 1980s through the 1990s and 2000s and made many international trips with him. These included visits to Botswana, Samoa, Indonesia, the Andean countries, and of course many visits to Brazil. He was always an amazing friend who pushed everyone around him to expand their thinking on a wide variety of issues and to not just accept established ideas. I learned a great deal from him, and always enjoyed his company. In the many different positions he held, he was able to save species, create many new protected areas, influence public policies, and move large amounts of funding to places that needed it most. What is more, he helped to train many students while in his university positions, and they continue to carry his legacy forward today.

Gustavo was truly a unique individual, a great leader, and a loyal friend. I will miss him, as will many other people whose lives he influenced in so many ways. Gustavo is survived by his mother Marisa, his sister Anna, his wife Glaucia, his three sons, Bruno, Lucas and Caio, and a grandson, Bernardo.

Thank you, Gustavo

I still can’t quite believe that Gustavo is gone – mentor, trusted advisor, and friend for more than 20 years. We first met at the Society for Conservation Biology Conference in Maryland in 1999; I was just finishing a postdoc with The Nature Conservancy and Univ Arkansas on Latin American bird conservation; Gustavo was the newly-appointed Executive Director of Conservation International’s Center for Applied Biodiversity Science (CABS), supported by what remains to this day the largest grant in the history of conservation science, USD 30m from the Moore Family Foundation. His name was doubly in the highlights that year, having just published, with Russ and Cristina Mittermeier, Jennifer Kent, and Norman Myers, “Biodiversity Hotspots for Conservation Priorities” in Nature – likely the most-influential conservation science paper ever (google scholar reports >33,500 citations to date).

Gustavo recruited me to CABS, where I worked for a decade. We shared enthusiasm for Latin American biodiversity, tennis, and beer! I had the privilege at CABS to be a peer of dozens of others, many of them now leaders in the conservation community in their own right, all of us under Gustavo’s leadership.

With his guidance and inspiration, CABS tackled numerous key topics at the forefront of conservation science, including the first global gap analysis of protected areas and biodiversity (led by Ana Rodrigues in 2004 in Nature), the first global analysis of protected area effectiveness (led by Aaron Bruner in 2004 in Science), the first assessments of extinction risk facing the world’s amphibians (led by Simon Stuart in 2008 in Science), mammals (led by Jan Schipper in 2008 in Science), and corals (led by Kent Carpenter in 2008 in Science), and a comprehensive review of global biodiversity conservation priorities (led by myself in 2006 in Science).

Gustavo was already deeply connected to IUCN, serving a leading role, for example, at the 2004 World Parks Congress in Durban, and championing the publication of the WCPA Best Practice Protected Area Guidelines No. 15 on Key Biodiversity Areas (led by Penny Langhammer in 2007). It was a time of enormous excitement and camaraderie, imbued with a sense of forging the still-young discipline of conservation science to support conservation practice at the global scale – all guided by Gustavo’s grand vision.

This vision continued with Gustavo’s subsequent role as Global Environment Facility Director of Programs. We stayed in close touch subsequent to my own move to IUCN, not least through IUCN’s role as an GEF implementing agency, collaborating in efforts on the global commons and on science-based targets. We were honoured to have Gustavo as a moderator of the Knowledge stream of the IUCN World Conservation Congress in Marseille in 2021, reflecting as ever his dedication to underpinning conservation policy, practice, and funding with robust science. He and I were emailing shared excitement over the new IUCN work on assessing “Nature Positive” commitments up until just a few hours before his passing.

Thank you, Gustavo – you embodied the “science-policy interface” for conservation, and will be deeply missed around the conservation world.

On behalf of my mother and me, we thank you.
That fact that he was not only respected in his field worldwide, but also loved, brings us some comfort.
He's gone too soon.

Sadly knew about Gustavo passed away through internet when I followed COP 15 Biodiversity in Montreal on 13 Dec 2022. Had good times with him during graduate studies in Florida in the 80's. Kind, gentle and friendly. RIP.
