A comparison of land cover maps to define vegetation classes of fire risk in Brazil

open access: yesBiodiversidade Brasileira, 2019
Natural fires are essential in the structure and functioning of many ecosystems in the world. Some vegetation types are more vulnerable to fire, e.g.tropical forests, whereas others are fire dependent, like savannas.

Activating dark earths: somatosoils and the carbonic loops of Amazonian ecologies

open access: yesJournal of the Royal Anthropological Institute, Volume 28, Issue 3, Page 854-874, September 2022., 2022
Abstract Inspired by the fertility and climate change‐mitigation properties of the so‐called Amazonian Dark Earths (ADEs), soil science has devised a technoscientific replica, a soil amendment known as biochar, intended to improve agricultural sustainability and carbon storage in the biosphere. Drawing on fieldwork with Afroindigenous horticulturalists,

Calcification accretion units (CAUs): A standardized approach for quantifying recruitment and calcium carbonate accretion in marine habitats

open access: yesMethods in Ecology and Evolution, Volume 13, Issue 7, Page 1436-1446, July 2022., 2022
Abstract Standardized metrics that quantify a component of ecosystem functioning are essential for evaluating the current status of coastal marine habitats and for monitoring how ecologically important ecosystems are changing in response to global and local environmental change.

An alert system for Seasonal Fire probability forecast for South American Protected Areas

open access: yesClimate Resilience and Sustainability, Volume 1, Issue 1, February 2022., 2022
We considered five variables that represent the anthropogenic and climatological conditions that increase the probability of fire occurrence. The anthropogenic components of the forecast are the (i) trend in the number of active fires over the past three years and (ii) accumulated number of active fires over the same period.

Amazon Hydrology From Space: Scientific Advances and Future Challenges

open access: yesReviews of Geophysics, Volume 59, Issue 4, December 2021., 2021
Abstract As the largest river basin on Earth, the Amazon is of major importance to the world's climate and water resources. Over the past decades, advances in satellite‐based remote sensing (RS) have brought our understanding of its terrestrial water cycle and the associated hydrological processes to a new era.

Why forest fails to recover after repeated wildfires in Amazonian floodplains? Experimental evidence on tree recruitment limitation

open access: yesJournal of Ecology, Volume 109, Issue 10, Page 3473-3486, October 2021., 2021
Our experimental evidence suggests that soil nutrient limitations may slow down forest recovery after repeated wildfires in Amazonian floodplains. Yet, because floodplain trees are able to germinate from seeds and establish successfully in twice burnt forests, seed limitation seems to be the reason why forest recovery fails persistently. Seeding native

Public participation, indigenous peoples’ land rights and major infrastructure projects in the Amazon: The case for a human rights assessment framework

open access: yesReview of European, Comparative &International Environmental Law, Volume 30, Issue 2, Page 184-196, July 2021., 2021
Abstract The recognition of land title and demarcation of indigenous peoples’ ancestral lands and the guarantee of the rights of consultation and free, prior and informed consent in the context of large infrastructure projects represent some of the major challenges for indigenous peoples and communities in the Amazon States.
