This book discusses techniques for predicting, preventing and controlling the hydrogeological instability of slopes consisting of cohesive soils. The proposed methodology is practical and innovative, and assumes a dynamic valence in defining the deformation process of underground failure as well as its activation through the assumption of a four-dimensional space-time continuum. This latter aspect is crucial for predicting a landslide in time to control it. At present, predicting, preventing and controlling hydrogeological instability in cohesive soils relies on mathematical modelling using specific software, the predictive reliability of which is rather deficient. Such modelling is based upon deterministic processes, which are entirely unsuitable for dealing with the complexity of vital processes occurring during the genesis of a landslide. In this work, the three-dimensional vision of a landslide as a set of distinct and independent phenomena is abandoned and the prediction and prevention of hydrogeological instability is pursued through the alternative of an indivisible totality of natural phenomena that includes the time factor. The book is of interest to graduates and researchers of applied geology, geotechnical, environmental and civil engineering, as well as professionals in the fields of hydrogeology and natural hazards.

Improving the durability of reinforced concrete structures is a mandatory strategy to reduce the environmental impact of construction materials together with aiming to limit carbon dioxide emissions, energy consumption and natural raw materials depletion. Hence, for both new and existing concrete structures, proper protective techniques are required to prevent premature failure induced by environmental aggressive agents. The book presents the most innovative findings both in designing durable new constructions and toward solving durability deficiencies in existing concrete structures, such as innovative special coatings, hydrophobic impregnations and pore blocking treatments that are very efficient in severe aggressive environments (seawater, biocorrosion, etc.). Moreover, migrant corrosion inhibitors applied on concrete surfaces are able to greatly improve resistance against both chloride and CO2. Finally, special reinforcements and fibers, together with a proper designed cathodic protection, can greatly contribute to obtaining long-life reinforced concrete structures, significantly increasing the sustainability of concrete construction.

Ce livre est un outil. Une invitation à devenir des alliés, à soulever des questions sur les complexités et les opportunités des spécificités d’un site terrestre. C'est un appel à une alliance avec les plantes. Elles nous permettent de raconter des histoires, même très douloureuses, et de pénétrer la stratification de l'histoire : leurs racines l'ont habitée et leurs graines sont prêtes à germer et à donner un nouveau sens. Lorsque nous pensons à l'intensité et à la violence des processus d'extraction coloniale, la République démocratique du Congo est l'un des endroits du monde qui les représente le mieux. Ex-Situ signifie embrasser ce qui émerge d'une localité, l'écouter, apprendre d'elle, comprendre sa valeur et la partager. Pour réparer un écosystème, nous devons d'abord réparer le système économique occidental, ses valeurs, ses récits, ses enseignements et ses institutions qui pourrissent encore dans nos sociétés identitaires, extractives, consuméristes et nationalistes. Agir avec la culture des plantes restauratrices, planter et reconstruire sur les détritus des écosystèmes toxiques, en essayant de les régénérer, est l'acte le plus sensé et le plus significatif que l'on puisse faire.

The FAIR Almanac 2019 is aimed as a tool that gathers practices, knowledge and perspectives in form of a year calendar, generated during the State Of The Arts' Summer Camp. It shall discuss and develop five core fields of fairness in the arts: solidarity, ethics, diversity, ecology, and empowerment. The annually renewed Almanach shall be come a key instrument for a continuous discussion about working conditions in the arts.
