I am a Colombian soil microbiologist and researcher with more than 15 years of interdisciplinary experience in the field and laboratory studying Amazon soils from their biotic components, biogeochemical interactions, uses of soil by indigenous and non-indigenous people, and their effects on it. I am the current director of the Leticia branch of the Instituto Amazónico de Investigaciones Científicas, Sinchi.

When I decided to become a soil microbiologist, I knew that the soil could be the most diverse environment in the world, but there was minimal information regarding how extremely diverse Amazonian soils are. Today we know Amazonian soils contain more than 700 different insects and arachnids, including around 180 different species of ants and more than 80 different species of termites, five different families of earthworms and around 40% of the world’s diversity of a group of beneficial fungi denominated arbuscular mycorrhizal fungi. Most Amazonian soils are acidic with low fertility. For many years researchers, colonists and explorers believed that human populations in the Amazon region were limited to small groups with simple social organizations that live in a simple manner with little or no technological developments. However, the Amazon region has been inhabited by many ancestral indigenous communities (an approximated 10 million people before the discovery of America by Europeans) who lived in complex and populated settlements with thousands of people. They needed to produce (through hunting, fishing and cultivation) enough food to sustain these settlements, much like the indigenous communities of today. But a common denominator between ancient and contemporary indigenous communities is that they do not perceive low-fertility Amazonian soils as a constraint for food production. Most productive soils are rich in minerals that are nutrients for plants, and these minerals come from parental rocks that were also rich in these minerals. The parental material from which Amazonian soils originate are rich in kaolinite, which is a clay poor in nutrients, so the mineral portion of Amazonian soils does not supply nutrients to plants. Most of the phosphorus, which is essential for plants to elaborate proteins and energy, comes from organic matter and not from the mineral portion of soils. The acidity of Amazonian soils also...

Traditional Indigenous territories are complex, adaptable, and resilient socio-ecological systems that contain the majority of the world’s biocultural diversity. But can Indigenous Peoples play a leading role in both combating climate change and preventing the next pandemic? Right now, there is a fair amount of rhetoric being flung about connecting, comparing, and contrasting the COVID-19 pandemic to climate change and the “sixth extinction” of biodiversity. In Indigenous worldviews—as well as in complex systems science—all these crises represent “maladies” caused by the profound unbalancing of our interconnected living planet. From his home in self-isolation in the Colombian Amazon, Koreguaje Indigenous leader Juven Piranga recently told me: “Our Elders agree that Mother Earth is causing this pandemic to clean the present state of the world, to rid us of the bad energies, and to counteract the pervasive greed and exploitation and disrespect. White people come here to our territories to exploit Mother Earth, for gold and timber and much more, and this affects everyone, and it is our responsibility to protect Mother Earth, so we are also punished. We need to reinforce our autonomy to stop these practices and restore balance.” While still not garnering nearly as much attention as it deserves, Indigenous Peoples’ role as partners in climate change mitigation is fairly well established in research, and gaining more attention internationally from both policymakers and the general public. The “Guardians of the Forest” paradigm recognizes Indigenous communities as stewards of the immense biodiversity and “ecosystem services” (or better, ecosystem functions) of tropical forests. Globally, the forested territories of Indigenous communities store at least 300 billion metric tons of carbon, above and below ground. Mounting evidence has shown that Indigenous communities with secure rights and tenure to their collectively held lands have extremely low rates of deforestation and land degradation. Additionally, while...

The longest running successful experiments in sustainable human land use are found within the collectively held lands of traditional communities, who have lived for generations in balance with the ecosystems of their ancestral territories. Looking to Indigenous socio-ecological system...
