This study aims to provide a better understanding of the corelation between pollen and vegetation. There are differences in pollen productivity among different taxa that cause a non-linear relationship between pollen dispersal and vegetation data. Four elevational gradients in the Catalan Pyrenees, ranging from alpine (2750 m) to montane-basal environments (797 m), were studied. A detailed map of vegetation cover was used, and a reclassification into eight taxonomic categories that represent at least 80% of the pollen spectra was made. For each point, a moss sample (used as a pollen trap) was collected, and the percentage of vegetation cover was measured at different radii. Additionally, a detailed plant inventory was made a few meters around each point.

The pollen results showed a complete dominance of Pinus percentages, making it difficult to perceive the dynamics of other relevant taxa. In alpine environments, Poaceae is always clearly underrepresented due to the long transport of Pinus pollen. Moreover, grazing often leaves no time for plants to flower, and some species of Poaceae show changes between sexual and vegetative reproduction in response to herbivory. Additionally, there are groups within this family where cleistogamy is quite common, causing low pollen dispersion. The pollen percentages of Abies alba are highly underrepresented. It appears that a significant portion of its pollen grains settle within less than 100 meters from the sampling point. Due to the size, shape, and density of fir pollens, the decline in pollen deposition with distance from the source is remarkable. Subsequently, it can be stated that the records in the Catalan Pyrenees with high percentages of fir pollen found during the middle Holocene would indicate the presence of dense and mature fir forests nearby the coring point. Betula and Corylus populations present more unpredictable pollen percentages, probably because they act as secondary communities.

La Vuelta del Paraguayo es un barrio de la ciudad de Santa Fe con más de 100 años de historia y se encuentra ubicado en el valle aluvial del Río Paraná, lo que hace que periódicamente sea afectado por las crecidas del río y las inundaciones. Desde el año 2008, tras la sanción de una ordenanza municipal, el barrio empezó a considerarse como zona de “riesgo hídrico”, lo que conllevó a amenazas de desalojo y relocalización. Sin embargo, las personas que habitan el territorio sostienen que la política de “riesgo hídrico” encubre la especulación inmobiliaria y el avance de una obra de infraestructura en el marco de la IIRSA. La organización política y social Proyecto Revuelta, principalmente compuesta por mujeres, se opone a la perspectiva de “riesgo” del río y propone una mirada de “convivencia” con él. A través de entrevistas etnográficas y en movimiento, se recuperaron las voces de las mujeres de la organización del barrio para analizar cómo perciben y viven la vida en un territorio que convive con los ciclos del río, así como lo que defienden de su territorio y por qué lo hacen.

Nowadays the engines of national economies are urban economies whose development is increasingly determined by creative economy, digital solutions, and innovation. In the development of cities (especially of smart cities), digital information and communication technologies have a decisive role. The basic question of the presentation to be answered is to what extent do digitalization and smart solutions contribute to increasing the competitiveness of Hungarian cities and what geographical patterns can be drawn up? Using these big data sets, we will explore the geographical characteristics and the territorial patterns of digitalization, including cell phone usage, and explore the characteristics of mobile usage flow. In so doing, we determine digital nodes (key mobility patterns and flows) based on mobile cell information and we explore the spatial and social characteristics of mobile phone usage. We will attempt to highlight the city network nodes and will provide a ranking list for cities. Using geocoded inbound and outbound call records we outline the connectedness of geographical units. Using the large scale telecommunication data we will define the innovation and knowledge transfer network position of Hungarian towns based on their centrality/periphery. In addition, the database will allow us to explore the demographic and technological conditions of mobile usage, whereby we will draw the social and territorial characteristics of mobile usage of the X, Y and Z generations

Mobility became a growing and important factor of today. Different types of mobility have different effects to society, economy and environment. The global problems, originated after the II. World War, are grown-up to the UN level in 70’s. The SDGs (Sustainable Development Goals) are in implementation since 2016. Role of mobility processes cannot be neglect3ed._x000D_
Migration, circulation causes positive and negative consequences to many fields in effected countries. These could be explored in demography, employment structure, national budget, many areas of economy, consumption, culture, etc. We can find many relations between mobility types and sustainable development, its implementation. Relations can found not only point of causes but of consequences also. E.g. migration is a very important movement between undeveloped an developed countries. One of reasons is climate change that his homeland becomes uninhabitable or income cannot be enough to live. The outward country loose part of his manpower and inward country get it. However these migrants have other culture, behaviour. If we take into focus SDGs we could find that many aspects are contrary to some of them. Circulation, especially if it is very frequent, does not match the principle of sustainable development. _x000D_
To explore many of such relationships could be not only task for geography but could be useful for policy makers. _x000D_

The problem of public transport in the city of Encarnación dates back several years, despite constant attempts to improve the service, currently there is no progress in this regard. The constant complaints from the users refer to the infrequency, lateness and poor condition of the buses. Due to the problems that the public transport system of the city currently has, citizen participation becomes totally necessary and of great importance as a means of governance aimed at improving the public transport system of the city. For all of the above, this research focused on analyzing the importance of citizen participation as a means of governance for the quality of the public transport service in the city of Encarnación, as well as specific objectives: Define the concept of citizen participation from the public management perspective; Describe the operation and organizational composition of the public transport system of the city of Encarnación; Identify the mechanisms and spaces for citizen participation in the public transport system of the city of Encarnación. Regarding the methodology used, it was a mixed or qualitative-quantitative investigation. For this, the survey was used, based on a non-probabilistic sample of 100 public transport users, as well as the interview, already with 2 public transport businessmen in the city of Encarnación, being a non-probabilistic sample for convenience. The result of this investigation was that citizen participation is a means of direct involvement aimed at generating quality public services, since it involves and commits the population in planning, decision-making, cost control and prevention of the corruption.

Spatial mobility of the population represents an important demographic and geographical phenomenon of particular importance for science and various areas of social practice. In studies of the relations between the city and surroundings commuters and daily urban systems play an important role. Existence of larger settlements, centers of such systems, with significant variations in the internal spatial-functional organization, raises the question: where do these commuters actually go? In such cases, it is necessary to distinguish parts of the settlement that have a primary function of work center and others that have a dominant residential function. The process of settlement parts differentiation requires the use of not only commuting flows data, but also data on intra-settlement daily population mobility. The model of the spatial manifestation of the labor force daily mobility is a proven starting point for the research of daily urban systems. It contains the most important components for the population daily mobility analysis: demographic, functional and spatial. In this research, an adapted model was used for extracting and planning subsystems, where the core of the daily urban subsystem is only one part of the settlement. As a case study, the settlement of Belgrade (the capital and the most important settlement in the geosystem of Serbia) was taken, whose territory is administratively divided between ten city municipalities, which statistically can be viewed as separate entities. The model was tested on the basis of data from two consecutive Censuses, between which significant functional and demographic changes occurred in the observed territory. Accordingly, the spatial coverage of each of the ten daily urban subsystems, their hierarchy, the volume of daily labor mobility, as well as changes in the inter-census period, were analyzed.

The realm of spatial mobility may range from the routine moves of corporeal body to circular and other systems of movements at local, regional, national, international, and global levels. The growing volumes and the increase in frequency of spatial moves have become the megatrend since the collapse of feudalistic regimes worldwide. Several research echoed the interrelationship between the elements of moves. As new phenomena, multiple displacements from one home to another gradually grew during the epoch of globalisation.
The development of political and administrative thinking about migratory politics and policies is in late and/or plans in advance from the point of view of reality. It has been starting the term of migration policy for decades, for instance. Later, a sort of broader concept, namely, the migration management has become more popular in national and international circles. Nowadays, the governance of migration might replace the previous two terms without clear ordering and bordering. This polemical progress reflects the necessity of the creation of original research in these subject matters multiplied by recent crises context.
The aim of this session is to provide fresh ideas for contributors and participants and to clarify the open questions surrounding us. In parallel with the formulation of scientific dialogues, the applied aim of the session is to bear original proposals erected from the concept of the governance of territorial mobilities for policymakers and other stakeholders at many spatial levels. The oral session proposed needs to be in English.

ID Abstract:

We pretend that discussing governance of territorial mobilities needs to highlight the local forms of governance. Even if the national states still claim authority over the immigration issues through visas and citizenship policies, cities are mostly the places where migrants and refugees live and develop a sense of belonging. Consequently we consider that in terms of migrant inclusion, we need to give a special focus on local forms of governance of mobilities such as these solidarity cities called in the US and Canada “sanctuary cities” and in Europe “cities of refuge”. A common urban approach describes them as local initiatives, policies and practices towards accommodating and protecting undocumented migrants and refugees. Also, what commonly highlights and regroups solidarity cities are their same discourses and practices to response to national immigration exclusive policies and consequently their same fight for “elevating the urban as the scale at which membership is enacted” (Bauder, 2017). Precisely, the recent crisis context of Covid-19 reflected the paper of these local governance of territorial mobilities that worked on facilitating the access to basic necessities such as sanitarian protection, healthcare services and economical support that other policy-makers might have left aside towards undocumented migrants. In brief, this presentation provides a comprehensive understanding of the role of local governance in the recent pandemic and the importance of discussing urban scale jurisdiction when we think about migratory policies and especially for the case of undocumented immigration.

The contribution deals with the international circular migration which has globally become a buzzword in scientific, political, and administrative circles since the new century. We concentrate on a general inner feature of the phenomenon which is the common root of false ideas and measures surrounding human circulation, namely their dual nature. The literature echoes wide variety of conceptualisations of international circular migration. However, the investigation and application of double characteristic is absent. On one hand, circular migration is a type of migration as a simple event, on the other hand that is a repeat process or a complete system. First aim of the presentation is to discuss the event-system dilemma in general and to provide an illustration with empirical evidence come from Hungary in particular. Moreover, the authors try to contribute to the clarification of the general concept of human circular mobilities to foster scholars for sophisticated thinking and stakeholders for adequate policy making in global, regional, national, and local levels. As second aim, we we propose the core elements of a new legal status by national scale, namely circulator, which is a common challenge for scientists and practitioners dealing with the arena of circular mobilities.
