La gestion des pâturages affecte la dynamique du comportement d’ingestion et par conséquent les performances des animaux, ainsi que la dynamique des herbages pâturés et de la production fourragères. Ce processus peut être regardé à partir de plusieurs optiques et deux questions majeures sont posées: quel est l'objectif de la gestion des pâturages? et quel critère le fermier utilisera-t-il pour piloter ce processus? Dans ce contexte, un concept innovant de gestion du pâturage a été proposé basé sur le comportement d'ingestion des animaux au pâturage, le pâturage rotatinu (rotatinuous stocking). Partant du postulat que le principal facteur limitant la production au pâturage est le temps nécessaire à ingérer le fourrage pâturé, l'objectif du pâturage rotatinu est permettre aux animaux de maximiser en tout temps leur taux d’ingestion instantané. L’hypothèse démontrée dans un certain nombres d’espèces graminéennes est qu’il existe une structure idéale d’herbe traduite en hauteur d’herbe qui permet cette maximisation à utiliser comme objectif de gestion dans le pâturage rotatinu. L’objectif de cette thèse était de définir la structure idéale de pâturages de Palisadegrass (Urochloa brizantha). Dès lors, au moyen d’une expérience de pâturage de courte durée, nous avons examiné la relation entre la hauteur du couvert herbacé (20, 30, 40 et 60 cm) et le taux d’ingestion à court terme. Les résultats obtenus ont montré que la biomasse disponible était corrélée linéairement avec la hauteur de la végétation sans influence sur la densité volumétrique apparente du couvert. Le taux d'ingestion a présenté une réponse quadratique (p <0,01) à la hauteur du couvert, maximisé à environ 42 cm (57 g de MS min-1) (STIR = 29.0171 + 1.3314 (SH) - 0.015838 (SH2), R2= 0,17). Grazing management affects the dynamics of ingestive behavior and consequently animal performance and also the dynamics of grazed swards and herbage production. This process can be seen from several optics and two questions permeate the theme: what is the goal of grazing management? and what criterion will the manager use to drive this process? In this context, it was proposed an innovative sward management concept based on the ingestive behavior of grazing animals, the rotatinuous stocking. Based on the assumption that the main limiting factor of grazing animal production is the time required to ingest herbage, the goal of rotatinuous stocking is to allow animals to maximize their instant intake rate at all times. The hypothesis demonstrated in several grass species is that there is an ideal sward structure translated to sward height that allows this maximization to be used as a management objective in rotatinuous stocking. The objective of this thesis was to define the ideal sward structure for pastures of palisadegrass (Urochloa brizantha). Therefore, using a short grazing experiment, we examined the relationship between the sward height (20, 30, 40 and 60 cm) and the short-term intake rate. The results obtained showed that the available biomass correlated linearly with the sward height, without influencing the sward bulk density. The short-term intake rate presented a quadratic response (p < 0.01) to the sward heights, being maximized at approximately 42 cm (57 g DM min-1) (STIR= 29.0171 +1.3314(SH) - 0.015838(SH2), R2= 0.17).

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.

As a dynamic interface between agriculture and forestry, agroforestry has only recently been formally recognized as a relevant part of land use with ‘trees outside forest’ in important parts of the world—but not everywhere yet. The Sustainable Development Goals have called attention to the need for the multifunctionality of landscapes that simultaneously contribute to multiple goals. In the UN decade of landscape restoration, as well as in response to the climate change urgency and biodiversity extinction crisis, an increase in global tree cover is widely seen as desirable, but its management by farmers or forest managers remains contested. Agroforestry research relates tree–soil–crop–livestock interactions at the plot level with landscape-level analysis of social-ecological systems and efforts to transcend the historical dichotomy between forest and agriculture as separate policy domains. An ‘ecosystem services’ perspective quantifies land productivity, flows of water, net greenhouse gas emissions, and biodiversity conservation, and combines an ‘actor’ perspective (farmer, landscape manager) with that of ‘downstream’ stakeholders (in the same watershed, ecologically conscious consumers elsewhere, global citizens) and higher-level regulators designing land-use policies and spatial zoning.
