Yield and performance of sugarcane in on-farm interface with rubber in Brazil

Agroforestry systems are indicated as an alternative for sugarcane (Saccharum officinarum) cultivation in Piracicaba, SP, Brazil, however there are not many field experiments on plant performance under these conditions in the world. The objective of this work was to assess crop yield and partitioning in a sugarcane-rubber (Hevea brasiliensis) interface in on-farm conditions. The availability of irradiance for the crop along the interface was simulated and its effe ct over sugarcane dry matter production was tested. Crop yield was negatively affected by distance of the trees, but development and sucrose were not affected. Above ground dry matter increased from 16.6 to 51.5 t ha-1 from trees. Partitioning did not have a defined standard, as harvest index increased from 0.85 to 0.93, but specific leaf area was not significant along the transect, ranging from 13.48 to 15.73 m² kg-1. Light is the main factor of competition between the trees and the crop, but the relative importance of below ground interactions increases closer to the trees. Feasibility of the system depends on maturity of the trees and management strategies.

Direct numerical simulations of interface dynamics to link capillary pressure and total surface energy

The flow of two immiscible fluids through a porous medium depends on the complex interplay between gravity, capillarity, and viscous forces. The interaction between these forces and the geometry of the medium gives rise to a variety of complex flow regimes that are difficult to describe using continuum models. Although a number of pore-scale models have been employed, a careful investigation of the macroscopic effects of pore-scale processes requires methods based on conservation principles in order to reduce the number of modeling assumptions. In this work we perform direct numerical simulations of drainage by solving Navier-Stokes equations in the pore space and employing the Volume Of Fluid (VOF) method to track the evolution of the fluid-fluid interface. After demonstrating that the method is able to deal with large viscosity contrasts and model the transition from stable flow to viscous fingering, we focus on the macroscopic capillary pressure and we compare different definitions of this quantity under quasi-static and dynamic conditions. We show that the difference between the intrinsic phase-average pressures, which is commonly used as definition of Darcy-scale capillary pressure, is subject to several limitations and it is not accurate in presence of viscous effects or trapping. In contrast, a definition based on the variation of the total surface energy provides an accurate estimate of the macroscopic capillary pressure. This definition, which links the capillary pressure to its physical origin, allows a better separation of viscous effects and does not depend on the presence of trapped fluid clusters.

La responsabilité sociétale des organisations : des discours aux pratiques ?

La notion de responsabilité sociétale des organisations (RSO) a suscité un engouement considérable auprès d'un public de gestionnaires, consultants et chercheurs, ainsi que dans les sphères politiques, institutionnelles et médiatiques. Cependant, l'adoption du discours sur la RSO par la grande entreprise, les institutions et les organisations de toutes formes génère aussi un certain scepticisme... Cet ouvrage s'intéresse au lien crucial entre discours et pratiques de RSO. Englobant non seulement les entreprises privées mais aussi un large spectre d'organisations, il propose des cadres d'analyse et des exemples concrets de déploiement de la RSO dans un contexte francophone. Comment s'articulent les stratégies symboliques des acteurs et les actions concrètes mises en oeuvre dans les organisations ? Quelles difficultés doivent surmonter les gestionnaires pour passer du discours aux pratiques dans le domaine de la RSO ? Quels facteurs facilitent ou empêchent le maintien de pratiques socialement responsables dans les organisations ?
