Abstract

Earth’s atmosphere and oceans play individual and interconnected roles in regulating climate and the hydrological system, supporting organisms and ecosystems, and contributing to the well-being of human communities and economies. Recognizing the importance of these two geophysical fluids, NASA designed the Plankton, Aerosol, Cloud and ocean Ecosystems (PACE) mission to bring cutting edge technology to space borne measurements of the atmosphere and ocean. PACE will carry the Ocean Color Instrument (OCI), a radiometer with hyperspectral capability from the ultraviolet through the near-infrared, plus eight discreet shortwave infrared bands. Thus, OCI will measure the broadest solar spectrum of any NASA instrument, to date. PACE’s second instrument will be a Multi-Angle Polarimeter (MAP). MAP will be NASA’s first imaging polarimeter on board a comprehensive Earth science mission. These instruments bring new capability to the science community, but also new challenges. Fundamentals, such as basic radiative transfer models, require review, enhancements and benchmarking in order to meet the needs of the atmosphere-ocean communities in the PACE era. Both OCI and MAP will bring opportunities to continue heritage climate data records of aerosols and clouds and to advance characterization of these atmospheric constituents with new macrophysical and microphysical parameters. The ability to better characterize atmospheric constituents is a necessity to better separate ocean and atmosphere signals in order to fully realize the potential of PACE measurements for oceanic observations. Atmospheric correction in the PACE era must address the expanded wavelength range and resolution of OCI images, requiring new approaches that go beyond heritage algorithms. This Research Topic encompasses fundamental radiative transfer studies, with application to the atmosphere, ocean or coupled atmosphere-ocean system

Abstract

Ensiling is a technique that is used to store food, mainly vegetable crops, to feed the herd when the forage supply from the pastures is not enough to maintain the productive performance of the ruminant animals. However, silage can also be used as substrate for biogas production and other different purposes. In the past years, we have seen many advances in the knowledge about silage production utilization, and this book is a compilation and discussion of the outstanding scientific research activities concerning actually the most recent advances and technologies that have been studied about silage and future demands. It is directed to a broad public of readers - farmers, academics, students, or anyone just curious or interested in the subject.

Abstract

This work focuses on the behavior of different chemical elements of the biogeosphere throughout the history of the planet, in particular since the manifestation of accelerated anthropization (development of the industrial civilization).

Abstract

Deserts - vast, empty places where time appears to stand still. The very word conjures images of endless seas of sand, blistering heat and a virtual absence of life. However, deserts encompass a large variety of landscapes and life beyond our stereotypes. As well as magnificent Saharan dunes under blazing sun, the desert concept encompasses the intensely cold winters of the Gobi, the snow-covered expanse of Antarctica and the rock-strewn drylands of Pakistan. Deserts are environments in perpetual flux and home to peoples as diverse as their surroundings, peoples who grapple with a broad spectrum of cultural, political and environmental issues as they wrest livelihoods from marginal lands.

Abstract

Today, sustainability of a healthy freshwater ecosystem and its associated ecosystem services are hot issues with ever-growing attention placed upon them. We are increasingly recognizing that they are crucial for the survival of the aquatic biota and human beings on our planet. The efficient monitoring of water resources is fundamental for effective management of water quality and aquatic ecosystems. The first stage in sustainable ecosystem management is the evaluation of the current status of target ecosystems. Traditionally, and even today, physico-chemical parameters have mainly been used to evaluate the quality of water resources. However, they have a large limit to grab the wholeness of water system, particularly in the sense of ecosystem health and integrity, for which ecological monitoring should be based on biological factors. Various approaches are applicable to ecosystem health assessment at different levels of the biological hierarchy, from genes to ecosystems. This Special Issue is designed to improve scientific understanding and strategies for sound aquatic ecosystem management and services for researchers, decision makers, and stakeholders.

Abstract

Après avoir considéré les forêts comme une source de matière première quasi inépuisable pendant des décennies, le Canada s'est lancé dans une approche durable au début des années 1990. Ce changement de cap a de quoi surprendre. Voilà que soudainement un des pays phares d'une vision très industrielle des forêts, s'érige en bon élève voire en pionnier d'une politique forestière qui s'inscrit en total contrepoint de ce qui s'y est fait jusqu'alors. Une optique durable qui supplanterait l'horreur boréale en quelque sorte. Rallions-nous à l'évidence. Une telle réorientation ne va pas sans mal tant les intérêts économiques en jeu sont présents. En dépit de cette réalité très prégnante, les autorités fédérales se sont engagées dans toute une série de mesures pour promouvoir le développement durable. En cherchant à comprendre comment cela est possible, nous en arrivons à mettre en évidence le rôle d'un socio système très dense et complexe qui s'est profondément renouvelé depuis plus d'une trentaine d'années. Se déployant du local au global, ces groupes d'acteurs forgent un véritable construit social autour des forêts sans lequel le développement durable serait vraisemblablement impossible. Autrement dit cette nouvelle politique forestière telle qu'elle existe au Canada est d'abord et avant tout reflet de ce que le socio système en fait.
