Una aproximación volumétrica a la desagregación espacial de la población combinando cartografía temática y datos LIDAR
2016
[EN] Availability of high resolution population distribution data, independent of the administrative units in which demographic statistics are collected, is a real necessity in many fields: risk evaluation due to earthquakes, flooding or fires, to name just a few, integration between socio-demographic and environmental or geographical information collected in different formats, policy design for the provision public services, such as health, education or public transport, or mobility studies in urban areas or metropolitan regions. Because of this, the literature has explored various methods of population downscaling, collected at communality or census tract level, into smaller areas; typica…

Urban layout, landscape features and pedestrian usage
2007
ACL; International audience; The analysis of the factors which condition walking in the urban environment is an important issue in urban planning. The present work is based on the hypothesis that the landscape, in its entirety, plays a role in encouraging pedestrian movements. The frequency of pedestrian traffic in the streets is analyzed as a function of accessibility and landscape preferences with the help of a conceptual framework. By defining accessibility as the measurement of the integration of the space syntax, preferences are researched using multiple stepwise regression of visual variables. This method has been applied to an area in the city of Lille (France) where the pedestrian f…
Assessing land condition as a first step to achieving land degradation neutrality : A case study of the Republic of Srpska
2018
Abstract Land Degradation Neutrality (LDN) is a key voluntary and aspirational target of Sustainable Development Goal (SDG) 15 which urges countries to protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss. A first and critical important step in the implementation of LDN is assessing the current land condition using not only active restoration of degraded land, but also targeting land degradation drivers behind the land degradation process. In a first step to achieve these goals, countries were provided a global dataset for three sub-indicators of land degra…
"This is Ghanaian territory!": Land conflicts on a West African border
2003
Most African borders have remained permeable, not least because the colonial and postcolonial states have lacked the necessary resources to enforce them more rigidly, "top-down." In this article, I analyze the ways in which an African border has been dealt with "from below," partly ignored or subverted and partly appropriated. The border between Ghana and Burkina Faso, drawn up in 1898, was soon adopted by the borderlanders as a political resource, capable of shielding them from colonial tax and forced-labor requirements. Local networks of kinship and strategies of land use, on the other hand, usually ignored the border. Although the border cut through many earth-shrine areas, the indigenou…
Cartografía de vulnerabilidad frente a inundaciones en llanos mediterráneos. Caso de estudio del Barranc de Carraixet y Rambla de Poyo
2008
Este trabajo aborda la cartografía de vulnerabilidad frente a inundaciones, en dos pequeños llanos mediterráneos pertenecientes al Barranc de Carraixet y la Rambla de Poyo. Ambos forman parte del Área Metropolitana de Valencia, integrando las comarcas de l¿Horta Nord y l¿Horta Sud, respectivamente. Constituye un ensayo metodológico, basado en estimadores socioeconómicos sencillos, obtenidos a partir de los usos del suelo. La vulnerabilidad se evalúa en función del valor económico del suelo y de la exposición humana al peligro. El valor económico del suelo se calcula a partir del Catastro. La exposición se calcula para tres supuestos de densidad de ocupación del espacio en función de la fran…
Populist demand, economic development and regional identity across nine European countries: exploring regional patterns of variance
2019
Today, populism has gradually become one of the most talked about, most studied phenomena, both within and beyond academia. Most studies of populism focus on its conceptualisation, operationalisation, measurement or its outcomes. However, adding to the growing empirical analysis of populism, we propose to study populism as a regional-level phenomenon and explain regional patterns of variation in the populist demand. To do so, we develop a series of theoretical arguments from, which we subsequently test empirically. Specifically, we argue that higher levels of regional populism demand are associated with (i) economic hardship, (ii) strong institutional autonomy, (iii) strong territorial iden…
Jūras un sauszemes teritoriju funkcionālās sasaistes nodrošināšana pašvaldību teritorijas plānošanas procesā
2019
Jūras un sauszemes teritoriju izmantošana ir funkcionāli cieši saistīta. Lielākoties jūrā iegūtie resursi tiek izmantoti cilvēku ekonomisko darbību nodrošināšanai sauszemē. Ne visi teritorijas izmantošanas veidi ir savā starpā funkcionāli saistīti, taču tie var ietekmēt viena vai otra izmantošanas veida attīstības iespējas nākotnē. Lai novērstu pretrunas un konfliktu situācijas starp jūras un sauszemes teritorijas izmantošanas veidiem, būtiski ir saskaņot un koordinēt abu plānošanas telpu attīstību, ne tikai nacionālā un reģionālajā plānošanas līmenī, bet arī vietējā. Maģistra darba mērķis ir veicināt sauszemes un jūras telpiskās plānošanas savstarpējo funkcionālo sasaisti, izvērtējot iespē…
Changes in land surface temperatures and NDVI values over Europe between 1982 and 1999
2006
Abstract We used land surface temperature (LST) algorithms and NDVI values to estimate changes in vegetation in the European continent between 1982 and 1999 from the Pathfinder AVHRR Land (PAL) dataset. These two parameters are monitored through HANTS (Harmonic ANalysis of Time Series) software, which allows the simultaneous observation of mean value, first harmonic amplitude and phase behaviors in the same image. These results for each complete year of data show the effect of volcanic aerosols and orbital drift on PAL data. Comparison of time series of HANTS cloud-free time series with the original time series for various land cover proves that this software is useful for LST analysis, alt…
Fitting the Stocking Rate with Pastoral Resources to Manage and Preserve Mediterranean Forestlands: A Case Study
2015
Pasture practices have affected Mediterranean forest ecosystems for millennia, and they are still quite widespread in mountainous areas. Nevertheless, in the last decades, the stability of forest ecosystems has been jeopardized due to the abandonment of traditional agro-pastoral practices, so that the gradual reduction of open areas due to progressive succession processes has caused a high increase of grazing pressure by livestock and wild ungulates feeding on forest areas. This paper aims at showing a methodological approach for evaluating the effect of applying measures in order to improve the grazing value of grasslands and ecotonal patches and lower the grazing impact on native woodland…
