Interactions between atmosphere, ice sheet and ocean play a crucial role in the Antarctic climate. For example, sea-air exchanges in leads and polynyas can strengthen cyclonic activities by warming and water vapour loading of air masses while associated sea heat loss and brine rejection modify water density and contribute to the dense water formation. Due to the harsh weather conditions in Antarctica, climate and ocean models appear as suitable tools to complement the scarcity of observations and to study the Antarctic climate. Nonetheless, only few models are able to represent typical processes found at high latitudes such as katabatic winds, drifting snow for the atmosphere or sea ice formation, accretion and deformation for oceans. Furthermore, due to their high non-linearity, those processes are difficult to model as they occur at different spatial and temporal scales. Current models are often forced by outputs: atmospheric conditions are provided to ocean models and ocean models outputs are used as surface conditions in atmospheric models meaning air feedbacks on ocean (or inversely) are muted. One can think models should be coupled at each time steps to take into account instantaneous interactions. Nonetheless, this method involves (too) high computational costs. The main challenge of this coupling is to take into account air-ice-ocean interactions and the temporal scale of associated processes in order to define an appropriate coupling time step. We will present both ocean and ice-atmosphere processes relative to polar climates and the specificities of the two models as well as technical coupling aspects. [less ▲]

In Aidoo’s Changes: A Love Story (1991), the characters are constantly on the move: tropes of mobility recur throughout the novel. Cars, hotels, business and leisure travel, modern technologies and the figure of what can be referred to as the Afropolitan avant la lettre play a pivotal role in embodying meanings that pertain to class, gender, globalisation, and consumerism that mark the postcolonial African condition, and give the novel an articulately contemporary character. This article adopts a wholesale understanding of mobility in order to explore the ways in which Aidoo’s characters employ different forms of mobility in their processes of self-fashioning as modern African subjects. The article draws attention to the anxiety that informs African urban elites processes of self-fashioning, caught as they are between the tensions of the traditional and the modern. [less ▲]

Planning is not anymore seeing as a neutral concept. During a long period planning has been conducted as a technical activity only. Nevertheless, space “is no longer a neutral category as it was between the 1960s and the 1980s that is viewed as a container for economic and social processes, but is rather the result of social relations among people living in a certain area or region where culture and cultural influences play a crucial role”(Knieling & Othengrafen, 2009, p. xxiii)1. Planning is indeed deeply depending on cultural context of a country and a region. Since the 1990s, the term planning culture covers comparative spatial planning research. This concept can be define as “the collective ethos and dominant attitudes of planners regarding the appropriate role of the state, market forces, and civil society in influencing social outcomes” (Sanyal, 2005, p. xxi)2. To date, planning culture literature concentrates on listing the observations and expert analyses. Our goal is to operationalise this concept as a set of values and attitudes shared by a particular group of people. For this purpose, we use experimental economics to gain empirical evidences on planning practices. Our presentation will be structured in three parts. At first, we will develop the concept of planning culture and illustrate it by the comparison of planning in Belgium and in the Netherlands. Despite many common characteristics, planning in those two countries strongly differs. On the one hand, both countries are densely populated and their territories are relatively similar. Although, on the other hand, their urban form are highly contrasted. Indeed, Belgium is characterized by an extreme sprawl whereas Netherlands has controlled the sub-urbanization processes. The second part of our presentation will be dedicated to the explanation of experimental economics. Experimental economics are experiments motivated by economics questions. “Experiments are a controlled data generation process. ‘Control’ means that most factors which influence behaviour are held constant and only one factor of interest (the “treatment”) is varied at a time”(Croson and Gächter, 2010, p. 124)3. To illustrate the field, we will realise an experiment in real time with the audience.Finally, we will finish our presentation by presenting some results of our current research that intends to objectify the role of planning culture in urban development. Based on experimental economics, our research aims to study the risk aversion as well as the importance of trust and cooperation in the development of partnership. To do so, we have organized four experiments with urban planning stakeholders in three different countries: Belgium, the Netherlands and Norway. [less ▲]

Big Data and Geomatics : towards a new paradigm in spatial information management During the last decade, the technological advances allowed a massive acquisition of digital data whose volume grows exponentially. Going from location-based social networks to smartphones, users produce huge amounts of data that are located in space and time. The various exploitations of these large and heterogeneous datasets have created a new field called “Big Data”. As most of these data are characterized by spatial and temporal components, it has become the next challenge to handle for geomatics researchers within the next incoming year. In this presentation, we provide an overview of the main domains in geomatics that are impacted by big data. Related fields are among other things: terrestrial spatial data acquisition where the rise of powerful laser scanners, that can acquire millions of points per second in order to precisely represent built heritage in 3D, revolutionized topography; Global Navigation Satellite Systems (GNSS), powered by the European constellation Galileo, imply original researches able to increase the position accuracy of a simple smartphone user; remote sensing is now enriched by a wide open access capability thanks to Copernicus satellites which provide timely information for the management of the environment. In order to effectively manage and analyse information related to each of these revolutions, Geographical Information System (GIS) research uses innovative data storage strategies based on CityGML for 3D data, semantic web linked-data and non-structured databases (NoSQL) for the integration of heterogeneous information, data warehouses and OnLine Analytical Processing (OLAP) for decision support. The presentation is based on concrete applications about smart cities, remote sensing, firefighting… [less ▲]

CARAIB (for CARbon Assimilation In the Biosphere) is a state-of-the-art dynamic vegetation model (DVM), initially designed to study the role of the vegetation in the global carbon cycle and the vegetation behavior as a function of climate and soil. Motivated by the requirements of ecosystem management and land use planning studies, CARAIB was recently improved so as to deal with both natural and agricultural ecosystems and at a high resolution of 1km over Belgium. A new module, for crops and meadows, was added in the model, which deals with the specific processes (phenology) and management (sowing, harvesting,…) of these ecosystems. The spatial and temporal validation was carried out with different data sources : agricultural statistics, eddy-covariance site, field measurements,… The addition of the crop module has led to the improvement of the surface scheme, from now on including dynamic land use and land cover information. As well as describes the evolution of physical and biological processes, CARAIB has become an interesting tool to assess the sustainability under climate change of the ecological systems, in particular by the approach of the ecosystem goods and services. Indeed, if some model outputs can be directly read as quantitative indicators of ecosystem services (e.g. carbon sequestration), we have translated some of them to get, e.g., the crop yield (from net primary productivity) or an estimation of the soil erosion for simulation at the parcel level (from runoff and parcels characteristics). But whether an ecosystem services or land use planning studies, the crucial point for CARAIB is the landscape dynamics, which is not considered by the model, in the absence of anthropogenic, economic and societal factors in the system. In order to overcome this lack, CARAIB is now coupled with an agent-based model (ABM), to compose a land surface dynamics (LSD) module. The productivity and growth of natural and managed vegetation is given by the DVM to the ABM, which determines the shifts in land use and land cover. The LSD module is able to represent the mutual interactions between ecological and socio-economic systems and thus, to assess the sustainability of the different climate and socio-economic scenarios tested.

In Europe (and in Wallonia), most public policies related to regional development and economic development aim to stimulate/reinforce the ‘’territorial resources’’ in order to improve the competitiveness of the (Walloon, Belgian or European) firms. For instance, in Wallonia, one of the key action of the Marshall Plan (i.e. the main regional strategy in the domain of economic development) aims to “mobilize the territory” (in French, « mobilisation du territoire à destination du développement économique »). In this perspective, our objective is to quantify and analyse the territorial resources that impact the performance of Walloon or Belgian firms, with the final aim to advice the policy makers and to improve the related public policies. This topic is related to questions such as: Does a better accessibility of economic estates improve the performance of firms? Are cultural amenities (in order to attract talents) and land prices (in order to reduce their costs) strategic competitive advantages for firms? The poster describes some methodological issues of (in general) the PhD research and (particularly) one part of the research, concerning a multivariate statistics analysis of business accounting.

In Senegal river basin, large dams were built during the 1980’s to secure water resources after a decade of water scarcity in the 1970’s: Manantali in the upper basin with a reservoir of 12km3 and Diama close to estuary to avoid saltwater intrusion during dry season. Senegal river water resources are known under the supervision of Senegal River Basin Development Organization (OMVS), which defines water allocation between different goals (electricity, irrigation, flood-recession agriculture). The Senegal river valley, located on northern part of the basin (with low precipitation < 300 mm), deals with different socio-ecological changes, following thirty years of dam management. Hydrological changes are characterized by a new hydrological regime, especially by a higher irregularity of annual flood. The main change is the development of an irrigated agriculture along the floodplain, and the valley is a strategic place for national rice production. In these context livelihoods are particularly affected by change and uncertainties around climate change, hydrology and economy. The agricultural landscape is currently remodeled around irrigation, where traditional activities are still included and combined. The aims of this communication is to determine the influence of both changes, socio-economic and hydro-climatic, in the reorganization of the agricultural landscape of the middle Senegal river valley, and especially the way they interact together. Water management at different scales (basin level versus local level), diversification of agriculture and socio-demographic dynamics are some important factors of the socio-ecological resilience of the middle Senegal river valley to uncertainties and mutations.

In this presentation, we will focus on the Fuji Five Lakes region. Since 2013, Mt. Fuji and the Fuji Five Lakes area (Lake Motosu, Lake Shoji, Lake Sai, Lake Kawaguchi and Lake Yamanaka) are added on the world heritage list of UNESCO. Mt. Fuji is a main touristic attraction in Japan bringing each year 300 000 tourists. The Fuji Five Lakes are located at the foot of Mt. Fuji Volcano close to the triple junction where the North American Plate, the Eurasian plate and the Philippine Sea Plate meet. Therefore, the region can be impacted by Mt. Fuji volcanic eruption as well as by large magnitude earthquakes. Additionally, nearly every year, Japan is hit by strong winds, heavy rains with flood, landslides and high waves. These natural hazards may affect the Japanese economy by causing casualties and infrastructure damage. In the regions frequently affected by natural disasters like Japan, it is crucial to have a better knowledge of the recurrence times of such disasters in order to refine the probabilistic models. For that purpose, lacustrine sediments are often used. Lacustrine sediments retrieving by coring offer several advantages compared to onland drilling: the method is cheaper, the cores are easier to take and they have longer temporal span. Lacustrine sediments are generally good archives to record past natural hazards. However, each lake has its own particular setting and a different sensitivity to record paleohazards. Coupling geophysical data, sedimentological analysis and historical records is often required to identify natural paleohazards in the sedimentary records and to define the threshold sensitivity of the lake. Here, we will used Fuji Five Lakes as natural laboratory for the recording of paleohazards (typhoons, earthquakes and volcanic eruptions) and will discuss the sedimentary record of Lake Motosu, Lake Sai, Lake Yamanaka and Lake Kawaguchi over the last ca. 6000 years regarding their geomorphological characteristics.
