Quantifying the Spatial Footprint of Agriculture-Driven Edge Effects in a Global Deforestation Hotspot. [PDF]

Glob Chang Biol
Tropical dry forests face increasing pressure from agricultural expansion, but how this expansion impacts on remaining forests is unclear. We quantified and mapped agricultural edge effects on tree cover, shrub cover, and above‐ground biomass in the Argentine Chaco, a global deforestation hotspot.

Use of species' responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests. [PDF]

Conserv Biol
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress. [PDF]

Glob Chang Biol
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.

Prospects and perils in the geospatial turn of conservation. [PDF]

Conserv Biol
Abstract Conservation has embraced advances in big data and related digital technologies as key to preventing biodiversity loss, especially in the identification of areas of conservation priority based on spatial data, which we call the big geospatial data turn.

Downscaling global reference points to assess the sustainability of local fisheries. [PDF]

Conserv Biol
Abstract Multispecies coral reef fisheries are typically managed by local communities who often lack research and monitoring capacity, which prevents estimation of well‐defined sustainable reference points to perform locally relevant fishery assessments.

Navigating data challenges in socioeconomic impact assessments of conservation regimes. [PDF]

Conserv Biol
Abstract Scholars are increasingly assessing the impact of conservation interventions at national and regional scales with robust causal inference methods designed to emulate randomized control trials (quasi‐experimental methods). Although spatial and temporal data to measure habitat loss and gain with remote sensing tools are increasingly available ...

Assessing disturbances in surviving primary forests of Europe. [PDF]

Conserv Biol
Abstract Primary forests are of paramount importance for biodiversity conservation and the provision of ecosystem services. In Europe, these forests are scarce and threatened by human activities. However, a comprehensive assessment of the magnitude of disturbances in these forests is lacking, due in part to their incomplete mapping.

TIME SERIES OF SALT CRUSTS IMAGED BY A DUAL POLARIZATION SPACEBORNE SYNTHETIC APERTURE RADAR (SAR) AT C-BAND OVER AN ANDEAN ALTIPLANO SALAR OF NORTHERN CHILE [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
A dense time series of Synthetic Aperture Radar acquisitions at 6-day intervals between July 2017 to January 2019 collected with the C-band constellation Sentinel 1A and 1B is used to study salt crust evolution in an highland salar. Microwave response of

Development of a consistent global long-term burned area product (1982–2018) based on AVHRR-LTDR data

International Journal of Applied Earth Observations and Geoinformation, 2021
This paper presents the generation of a global long-term Burned Area (BA) product based on Advanced Very High Resolution Radiometer (AVHRR) images. The BA product was derived from the Land Long Term Data Record (LTDR), which provides a continuous dataset
