A review of droughts on the African continent: a geospatial and long-term perspective
TL;DR: A comprehensive review and analysis of the available literature and information on droughts to build a continental, regional and country level perspective on geospatial and temporal variation of Droughts in Africa is presented in this article.
Journal ArticleDOI
Drought characterization from a multivariate perspective: A review
Zengchao Hao,Vijay P. Singh +1 more
TL;DR: A comprehensive review of multivariate drought indices developed recently can be found in this article, where the authors provide useful information for operational drought characterization with current multivariate DIE indices and for the development of new multivariate DIDE indices.

Book ChapterDOI
Handbook of Drought Indicators and Indices
Mark Svoboda,Brian Fuchs +1 more
TL;DR: The authors discusses some of the most commonly used drought indicators/indices that are being applied across drought-prone regions, with the goal of advancing monitoring, early warning, and information delivery systems in support of risk-based drought management policies and preparedness plans.

Drought response of five conifer species under contrasting water availability suggests high vulnerability of Norway spruce and European larch
Mathieu Lévesque,Mathieu Lévesque,Matthias Saurer,Rolf T. W. Siegwolf,Britta Eilmann,Peter Brang,Harald Bugmann,Andreas Rigling +7 more
TL;DR: If summers become drier, trees growing on mesic sites will undergo significant growth reductions, whereas at their dry distribution limit in the Alps, tree growth of the highly sensitive spruce and larch may collapse, likely inducing dieback and compromising the provision of ecosystem services.

Red and photographic infrared linear combinations for monitoring vegetation
TL;DR: In this article, the relationship between various linear combinations of red and photographic infrared radiances and vegetation parameters is investigated, showing that red-IR combinations to be more significant than green-red combinations.

Remote sensing and image interpretation
TL;DR: In this article, the authors present a textbook for introductory courses in remote sensing, which includes concepts and foundations of remote sensing; elements of photographic systems; introduction to airphoto interpretation; air photo interpretation for terrain evaluation; photogrammetry; radiometric characteristics of aerial photographs; aerial thermography; multispectral scanning and spectral pattern recognition; microwave sensing; and remote sensing from space.

Remote Sensing and Image Interpretation
TL;DR: In this article, the concept of remote sensing elements of photogrammetry was introduced. Butterfly, thermal, and hyperspectral sensors were used to interpret multispectral, thermal and hypererspectral images.
The relationship of drought frequency and duration to time scales
TL;DR: The definition of drought has continually been a stumbling block for drought monitoring and analysis as mentioned in this paper, mainly related to the time period over which deficits accumulate and to the connection of the deficit in precipitation to deficits in usable water sources and the impacts that ensue.
