Abstract

Since the 1970s and particularly the works of Tüxen (1978) and Géhu & Rivas-Martínez (1981), dynamico-catenal phytosociology has facilitated the integration of vegetation dynamics by more precisely describing the trajectories of vegetation series. A national habitat mapping program (CarHAB), launched by France’s Ministry of Ecology, aims to map the vegetation and vegetation series of metropolitan France at a scale of 1: 25,000 by 2025. In this context, Corsica has been selected as a pilot region, due to its unique characteristics regarding Mediterranean and alticole vegetation. This book describes in detail the vegetation series and geoseries (ecology, structure, dynamic trajectories, effects of anthropogenic factors on vegetation dynamics, catenal positioning in the landscape) of two Corsican sectors: Cap Corse and Biguglia pond. These two study sites were selected using two methods: • For Cap Corse, the typology and mapping are based on an inductive approach, which seeks to understand the dynamics of vegetation by drawing on the mature, substitutional, pioneering and anthropogenic associations likely to exist within a tessellar envelope. These various dynamic stages characterize “the vegetation series” (sigmetum or synassociation), the fundamental unit of symphytosociology (Géhu 2006; Biondi 2011). The aim of symphytosociology is, therefore, to define the vegetation series; in other words, it seeks to identify the repetitive combinations of syntaxa under homogeneous ecological conditions. • For Biguglia pond, the typology and mapping are based on a deductive approach, which combines (under SIG) the ecological descriptor maps with the vegetation mapping, in order to reveal the tesselas and the natural potential vegetation that underlies them. Thanks to the improvement of GIS techniques, this approach has been frequently used to characterize plant landscapes from vegetation to vegetation geoseries since the 2000s, with applications to the conservation management of natural and semi-natural environments.

Abstract

This report examines the scientific basis for the use of remotely sensed data, particularly Normalized Difference Vegetation Index (NDVI), primarily for the assessment of land degradation at different scales and for a range of applications, including resilience of agro-ecosystems. Evidence is drawn from a wide range of investigations, primarily from the scientific peer-reviewed literature but also non-journal sources. The literature review has been corroborated by interviews with leading specialists in the field. The report reviews the use of NDVI for a range of themes related to land degradation, including land cover change, drought monitoring and early warning systems, desertification processes, greening trends, soil erosion and salinization, vegetation burning and recovery after fire, biodiversity loss, and soil carbon. This SpringerBrief also discusses the limits of the use of NDVI for land degradation assessment and potential for future directions of use. A substantial body of peer-reviewed research lends unequivocal support for the use of coarse-resolution time series of NDVI data for studying vegetation dynamics at global, continental and sub-continental levels. There is compelling evidence that these data are highly correlated with biophysically meaningful vegetation characteristics such as photosynthetic capacity and primary production that are closely related to land degradation and to agroecosystem resilience.

Abstract

The book presents a wide range of techniques for extracting information from satellite remote sensing images in forest fire danger assessment. It covers the main concepts involved in fire danger rating, and analyses the inputs derived from remotely sensed data for mapping fire danger at both the local and global scale. The questions addressed concern the estimation of fuel moisture content, the description of fuel structural properties, the estimation of meteorological danger indices, the analysis of human factors associated with fire ignition, and the integration of different risk factors in

Abstract

"Remote sensing is becoming an increasingly important tool for agriculturalists, ecologists, and land managers for the study of the earth's agricultural and natural vegetation, and can be applied to further our understanding of key environmental issues, including climate change and ecosystem management."--[book cover].
