The concepts <strong>and</strong> theory classically usedin agricultural soil mechanics <strong>and</strong> adopted from geomechanics (analytical solutions for stress propagation in soil,soil compressive strength, Finite Element Model (FEM)) have limitations that will be illustrated with h<strong>and</strong>s-onmodelling <strong>and</strong> measurements in the lab <strong>and</strong> in the field. As a new modelling approach for soil deformation,Discrete Element Models (DEM) will be used to underst<strong>and</strong> particle-particle contact problems, stress propagation<strong>and</strong> displacement behaviour <strong>of</strong> granular media. Both approaches (i.e. DEM <strong>and</strong> FEM) will be compared toexplore the mechanical behaviour <strong>of</strong> agricultural soils at the macroscale (DEM) <strong>and</strong> at the microscale (FEM). Asan alternative to the classical laboratory methods for soil stress-strain characterisation, the potential <strong>of</strong> nondestructivetechniques to characterise soil strength in situ (seismic methods) will be presented.The course will last seven days. Each day will begin with a lecture session. The second half <strong>of</strong> the day willinvolve h<strong>and</strong>s-on modelling <strong>and</strong> measurement activities. On the 7th day we call on the Ph.D. students toparticipate in a young scientist forum, where the aim is exchange <strong>of</strong> knowledge, experience, <strong>and</strong> ideas. Therewill also be a possibility <strong>of</strong> individual consultancy concerning experimental problems.Material to be covered includesGeneral Aspects <strong>of</strong> the Mechanical Behaviour <strong>of</strong> soils (stress theory, strain theory, stress-strain relations.Traditional <strong>Soil</strong> Mechanics Modelling (Elastic stress-strain relationships - analytical solutions, Elasto-plasticstress-strain relationships - FEM.Traditional <strong>Soil</strong> Mechanics Measurement Methods including compressive behaviour, shear strength, tensilestrength <strong>and</strong> penetrometer resistanceNew Approaches to Infer <strong>Soil</strong> Mechanical Models (non-destructive field methods to measure soil strength,particle arrangements measurements using three-dimensional imaging techniques)New Approaches to Model <strong>Soil</strong> Mechanical Behaviour (Distinct Element Modelling)Further information <strong>and</strong> inscription http://stair.agrsci.dk <strong>and</strong> follow the link to PhD courses.

IntroductionThe University Cadi Ayyad <strong>and</strong> the Faculté des Siences et Techniques (FST)<strong>of</strong> Marrakech would like to invite you to joinus for the 6th International Conference <strong>of</strong> the Urban <strong>Soil</strong>s Working Group, SUITMA, <strong>of</strong> the International Union <strong>of</strong><strong>Soil</strong> Sciences. Share in the latest information <strong>and</strong> ideas from around the world in this exciting <strong>and</strong> important field.Increasing urbanization is a worldwide phenomenon.According to the United Nations Population Division, one-half <strong>of</strong> the world's population now lives in cities <strong>and</strong> towns, <strong>and</strong>by 2030 this will reach 60 percent. Currently there are 20 mega-cities with more than 10 million inhabitants, many indeveloping countries. Also, humanity is facing major global changes, i.e. increasing world dem<strong>and</strong> in food <strong>and</strong> nonrenewableresources, climate change, biodiversity erosion, epidemic threats.SUITMAs (<strong>Soil</strong>s in Urban, Industrial, Traffic, Mining <strong>and</strong> Military Areas) are fundamental components <strong>of</strong> urbanecosystem. They are diverse <strong>and</strong> heterogeneous, <strong>and</strong> fulfill primary functions <strong>of</strong> utmost importance. Obviously they are apart <strong>of</strong> the answer imposed to humankind to meet major challenges. However, knowledge related to SUITMAs is stillfragmentary, which hinders their fundamental roles <strong>and</strong> impairs the management <strong>of</strong> urban areas.Objectives <strong>of</strong> SUITMA are:i) to increase knowledge about one <strong>of</strong> the most important frontiers in the field <strong>of</strong> soil science, <strong>and</strong>ii) to advocate the role <strong>of</strong> soil science in the decision making process for urban l<strong>and</strong> management.After successful events in Germany, France, Egypt, China, <strong>and</strong> the United States, the <strong>2011</strong> conference in Marrakech will<strong>of</strong>fer a further step forward in the knowledge <strong>of</strong> urban soils, focusing on the functions <strong>of</strong> SUITMAs in global changeissues. It will feature current research from around the world, <strong>and</strong> panel discussions on topical issues. Not only aredisciplines directly connected to soil science invited, but other scientific communities (e.g. economy, law, policy-making,health, l<strong>and</strong> planning) are most welcome to SUITMA 6.Traditionally, SUITMA puts emphasis on local features <strong>of</strong> urban soils. In this objective, beside a three-day conference (3,4 & 7 October <strong>2011</strong>) held at hotel Ryad Mogador Menara, Marrakech, a two-day field tour (5 & 6 October <strong>2011</strong>) will be<strong>of</strong>fered in the region <strong>of</strong> Marrakech to examine soils <strong>and</strong> l<strong>and</strong>scapes, soil-based restoration, research, <strong>and</strong> mapping projectsunder semi-arid climate, <strong>and</strong> a post-conference tour (9 - 12 October <strong>2011</strong>) will be organized in Senegal to address issuesrelated to urban soils under tropical conditions.We will be very pleased to welcome you at SUITMA 6 to have your ideas <strong>and</strong> experience integrated in major scientific <strong>and</strong>social issues.
