[Termes IGN] série temporelleRésumé : (Editeur) Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration. An accurate estimation of carbon stocks and an understanding of the carbon sources and sinks can aid the improvement and accuracy of carbon flux models, an important pre-requisite of climate change impact projections. Based on 15 research topics, this book demonstrates the role of remote sensing in quantifying above ground biomass (forest, grass, woodlands) across varying spatial and temporal scales. The innovative application areas of the book include algorithm development and implementation, accuracy assessment, scaling issues (local–regional–global biomass mapping), and the integration of microwaves (i.e. LiDAR), along with optical sensors, forest biomass mapping, rangeland productivity and abundance (grass biomass, density, cover), bush encroachment biomass, and seasonal and long-term biomass monitoring.

[Termes IGN] zone semi-arideRésumé : (éditeur) Evapotranspiration (ET) is a critical component of the water and energy balances, and the number of remote sensing-based ET products and estimation methods has increased in recent years. Various aspects of remote sensing of ET are reported in the 11 papers published in this book. The major research areas covered by this book include inter-comparison and performance evaluation of widely used one- and two-source energy balance models, a new dual-source model (Soil Plant Atmosphere and Remote Sensing Evapotranspiration, SPARSE), and a process-based model (ETMonitor); assessment of multi-source (e.g., remote sensing, reanalysis, and land surface model) ET products; development or improvement of data fusion frameworks to predict continuous daily ET at a high spatial resolution (field-scale or 30 m) by fusing the advanced spaceborne thermal emission reflectance radiometer (ASTER), the moderate resolution imaging spectroradiometer (MODIS), and Landsat data; and investigating uncertainties in ET estimates using an ET ensemble composed of several land surface models and diagnostic datasets. The effects of the differences between ET products on water resources and ecosystem management were also investigated. More accurate ET estimates and improved understanding of remotely sensed ET products are crucial for maximizing crop productivity while minimizing water losses and management costs.

[Vedettes matières IGN] Inventaire forestierRésumé : (éditeur) Forest ecosystems in Central Europe are changing as a result of anthropogenic influences and changing climate conditions. As such, a large-scale monitoring programme was undertaken in order to understand the influence of site modification, deposition of air pollutants, and climate. This book presents the scientific findings of this study for Germany, including the major challenges with regard to the future preservation and management of forest ecosystems under environmental change. In addition, it addresses a number of central questions: what are the main factors affecting forest stands and soil integrity? How, and how rapidly, are forest ecosystems changing? How diverse are the changes across Germany? What will be the main risks in sustainable forest management in the future? And how can policy support the development and maintenance of adaptive and resilient forests that provide essential ecosystem services, today and in the future? Helping readers understand the importance of soils and related ecosystem processes for future sustainable forestry, and sharing essential findings on environmental change and related changes in forest status and dynamics, the book is a valuable resource for researchers and policymakers interested in science-based decisions.

[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) Introduction : The growing demands of society on forests have pushed forward NFIs who had to evolve and adapt over time. However, in a context of forests being at the center of many challenges, reactivated by global changes, this adaptation has been particularly accelerated in recent years. The demands now comes from a broader public (national/international policy makers, industries, environmental organisations, research, people) who is seeking for more information, more precise and easily accessible. In order to respond to these demands, some NFIs are moving from a knowledge tool on forests to a somehow environmental monitoring system. These renewed inventories must be able to easily integrate new (diverse) needs and to be reactive in case of dramatic perturbations (fires, storms, massive dieback). In this context, NFIs must be powerful, responsive and easily adaptable tools. This involves a change in their design, from the sampling plan, to the provision of baseline information through revised estimation techniques using more and more auxiliary information, often derived from remote sensing. The purpose of the communication is to present the innovations implemented or under development in the French inventory to adapt a quite old (now 60 years) tool to this new context.
Materials and methods: The communication will present the recent changes in the French NFI :•sampling design (continuous inventory);•estimators and the use of external data thanks to post-stratification.
Results: We will insist on the search for flexibility of the French NFI design and the information system actually developed :•On the fly production of results via specific tools;•Easy addition, combination of new variables;•Improvement of estimates thanks to new data via post-stratification (DHM);•Derivation of the national tool to specific case (regional) studies : on demand inventories.•Reactivity after events like storms. Conclusion: A NFI is a work in progress, always evolving to address new needs, gain more precision, a finest resolution... at constant or decreasing costs. New solutions have to be found, new auxiliary data have to be mobilised in order to answer the multiple demands. Achieving that necessitate to find or form the future engineers and researchers who will build the next generation of NFIs. This question is crucial in a domain where human resources are rare.Numéro de notice : C2019-062 Affiliation des auteurs : LIF (2012-2019) Thématique : FORET Nature : Communication nature-HAL : ComSansActesPubliés-Unpublished DOI : sans Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=96977 This is my spot: characteristics of trees bearing Black Woodpecker cavities / Camille Puverel (2019)
