Teledetección ambiental: La observación de la Tierra desde el Espacio

Entorno Geografico, 2013
La teledetección, entendida como una técnica que implica la obtención a distancia de imágenes de la superficie de la Tierra, su tratamiento e interpretación para diferentes propósitos, inicialmente estuvo ligada principalmente a la fotografía aérea.

La Teledetección satelital y los sistemas de protección ambiental

Civilizar, 2005
La Teledetección ofrece grandes posibilidades para la realización de progresos en el conocimiento de la naturaleza, aunque todavía no se ha logrado todo lo que de ella se esperaba debido a que se deben realizar perfeccionamientos en el nivel de ...

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.
