Multiscalar Territorial Analysis - Historical and Conceptual Background

Conceptual background

A long-term policy need: Measuring territorial inequalities in Europe (1954-2014)

It is impossible to understand the origin of the implementation of the MTA package without taking into account the specificities of spatial planning in Europe and the need of monitoring tools and methods for measuring inequalities in Europe: Early the question of measurement of territorial inequalities has been raised by planners and policy makers. Without being exhaustive, let us remind from a political point of view some usages of statistics and cartography regarding the measure of territorial inequalities in a European context.

The first in-depth thought on regional inequalities from a geographical point of view in Europe came between the declaration of Schuman the 9th May 1950, which launch the European Coal and Steel Community; and the Rome treaty, which gives rise to the Economic European Union le 25th March 1957: in 1954 the Commission économique pour l'Europe des Nations Unies (UNECE) launched a study on economic inequalities within several countries of Europe [1]. Led by its Secretary General, the future Nobel Prize G. Myrdal, this report foreshadows the future policies of the European Union and forthcoming regional analysis of OECD: lagging regions are identified and the reasons of the development gaps tried to be explained. Thus, "winning factors" were specified: distance to population or production centers, geographical situation of regions (peripheric or not), modernity and productivity of economic structures, demographic dynamics, etc.

It is interesting to note that the statistic criteria used to measure territorial inequalities was in this study the deviation of each region to its country of belonging, and not to the overall study area (European Union in this case). The solution proposed to solve inequalities was consequently not to identify federalist mecanisms of solidarity at continental level. It was more directly to propose some tools for coordinating national policies and developing a comparative framework on causes and effects of territorial inequalities. Then, it is dependent to the sovereign countries to draw conclusions for implementing support policies for lagging territories. This approach is in fact very close to the problematics raised in 1948 for managing the funds of the Marshall Plan. And it is not surprising to remark that the emergence of the main national policies in spatial planning started during the same period in France (creation of the DATAR in 1963), in Italy (Casa del Mezzogiorno, 1950) or in Germany (creation of the Bundesministerium für Wohnungswesen, Städtebau une Raumordnung in 1961). In all these cases, data availibility, adapted statistics and maps were and remind especially useful to support and foresee spatial planning policies.

On the opposite of the pioneer map of Myrdal (map on the left), which supported a research on the causes of income inequalities and the possibilities existing to reduce them in a Keynesian framework of internal redistribution, the map proposed by the European Commission in 2014 (map on the right) is totally driven by the regional policy reglementation of the European Union [2]. This maps leads the allocation of the main funds of the EU regional policy: The statistics criteria used to measure territorial inequalities is the Gross Domestic Product in PPS at NUTS2 level. This indicator is chosen to define elligible regions to the EU cohesion policy (GDP per capita under 75 % of the average of the European Union). In this case and in a very normative aspect, the measure of the deviation to a territorial context of reference (the European Union) is used to apply European policies and deliver a significant amount of funds (182 billion Euros dedicated to "less developed regions", e.g. under 75 % of the EU average).

The analysis of these two maps reveals several possibilities for measuring territorial inequalities and display it on maps. It highlights also the important need - whatever the period considered - to define an adapted methodology to measure regional inequalities [3], [4], [5].

Nowadays, the need to measure territorial disparities at lower scales become more and more important. The historical planning issues managed at national level is in a large extent transferred to regions and local authorities. To act locally, these new territories of governance requires statistical evidences to understand the structure and the dynamics of their territories. As displayed below, a lot of urban agencies and experts financed by public fundings were recently created to provide local pictures of local dynamics (Metropole du Grand Paris, Metropole du Grand Lyon, Greater London, etc.). Here again, the need of territorial information is high.

Conceptualisation of the MTA analysis in this context

The MTA methodology has been set up in this context during the years 2000's [6]. It has been initiated by the HyperCarte research group, which associate 4 research teams in geography and computer science (cf below). A major output coming from this research group was HyperAtlas, a Java application for the multiscalar territorial analysis (MTA). This tool has been developed with the support of several European institutions within research projects (DG REGIO, ESPON, European Environmental Agency, European Parliament).

The basic idea behind the HyperAtlas and the MTA concept is that there is never a single and objective way to display a social phenomena on maps, but an infinity. It depends on the hypothesis made by the observator regarding the contacts that can exist between individuals across the space and the time, regarding the influence of institutions within their territory of authority or for monitoring territorial impacts of policy measures.

MTA methods have been developed in order to highlight in a simple way such situation for hierarchical territorial divisions [7]. Territorial hierarchy is considered as a strict nesting of territories, for instance:

The central hypothesis behind the MTA consists to consider that the meaning of a statistical indicator is always dependant of territorial context of reference. Taking a concrete example, knowing that the Gross Domestic Product in 2008 of Nord-Pas-de-Calais is 24 700 euros per capita provides few information itself. It is rather interesting to understand how this region stands as regard to the European Union average (22 800 euros, + 7,7 %), to its country of belonging (France, 30 400 euros, - 18 %) or as compared to its neighbouring regions (24 950 euros, - 1 %). The combination of these deviation measures allows to highlight regions in favourable situations, lagging regions and also to depict contractory situations (e.g. a rich region in a poor country, and vice-versa).

The originality of the methodology proposed by the HyperCarte research group is consequently to propose to compare in a same environment (HyperAtlas, or R with this package) several possibilities for measuring territorial inequality, according to three territorial contexts (global, territorial, spatial).

Teams involvled in the HyperCarte Research Group

The HyperCarte Research Group was founded in 1996 and has provided the main conceptual outputs proposed in this MTA package. It groups 4 research teams from Paris (RIATE and Géographie-cités) and Grenoble (STeamer and Mescal):

Resources

One of the major outputs of the HyperCarte Group was the development of HyperAtlas - A Java application proposing a path of investigation for exploring MTA inequalities.

HyperAtlas has been used many times by the past, for pedagogical purpose or research activitities in Brasil and regarding European Union inequalities. The MTA methodology proposed by HyperAtlas has also been implemended for decision making and monitoring in a policy context at EU (ESPON Program, European Parliament ) and national levels (Romania, Tunisia, Belgium, Nordic countries, France etc.).

The MTA methodology has been also follosed for analysing intra-urban voting geography at polling station level in Paris

The tool presentation (in French) remains the history of the tool, reveals its functionalities and propose two domain of applications (Income inequalities in Ile-de-France region / EU Cohesion Policy).

The HyperAtlas solution is one way to access to multiscalar inequalities. The aim of the MTA package consists in proposing to the community the main functionalities proposed by HyperAtlas in a R language.
