Cost-effective protection of biodiversity in the western Amazon

open access: yesBiological Conservation, 2019
The western Amazon needs to expand its protected-area system to ensure the conservation of its immense and threatened biodiversity. However, potential expansions often meet with resistance because of scarce government resources and competing social priorities.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Small-scale farms in the western Brazilian Amazon: can they benefit from carbon trade? [PDF]

open access: yes
Recently scientists have started to examine how land-uses and land-use technologies can help mitigate carbon emissions. The half million small-scale farmers inhabiting the Amazon frontier sequester large stocks of carbon in their forests and other land ...

A pilot variational coupled reanalysis based on the CESAM climate model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Wood density of forest species in integrated crop-livestock-forest system in the Brazilian Amazon: challenges and opportunities for Bertholletia excelsa, Dipteryx odorata, and Khaya grandifoliola

open access: yesRevista Brasileira de Ciências Ambientais
Wood density is the physical property directly related to the timber potential of a species and influences the environmental service of carbon storage and sequestration. Therefore, the objective of this study was to evaluate the wood density at different

Assimilation of solar‐induced fluorescence satellite observations in the European Centre for Medium‐Range Weather Forecasts integrated forecast system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This work demonstrates the potential of the assimilation of satellite solar‐induced fluorescence (SIF) retrievals at eight‐day and 0.1° resolutions in the integrated forecast system (IFS), developed at the European Centre for Medium‐Range Weather Forecasts (ECMWF), at global scale, to provide a more realistic representation of the vegetation temporal ...

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.
