Lower Brent prices and Saudi policy options: What’s shale oil got to do with it? / Lutz Kilian, Vox, 29/03/2016Lower oil prices are putting increasing pressure on Arab oil producers, and many pundits have been quick to blame US shale oil producers for the decline in prices and in Arab oil revenues. This column measures how much the the shale oil boom contributed to the fall in the global price of crude oil. The Brent price of crude oil since 2011 would have been as much as $10 per barrel higher in the absence of US shale oil.

In this context, Poland faces specific challenges due to its high reliance on domestic coal. The efforts undertaken by other coal intensive economies—like China—to reduce emissions could provide Poland with valuable lessons learned... lireGaspillage alimentaire, le poids des chiffres / Marie Moura, doctorante au Centre de sociologie des organisations, Sciences Po – USPC et Armèle Cloteau, doctorante au laboratoire Printemps, Université de Versailles Saint-Quentin en Yvelines – Université Paris-Saclay, the Conversation, 23/03/2016Des montagnes de fruits et de légumes comestibles mis en décharge aux invendus remplissant les bennes des supermarchés, le « gaspillage alimentaire » fait parler de lui. En France, une loi a même été votée en février 2016 pour lutter contre ce phénomène. C’est à travers des chiffres, des kilos voire des tonnes jetés régulièrement, que ce problème ancien est devenu aujourd’hui un véritable enjeu politique... lire
