Article
Gestión integral y uso múltiple del territorio son conceptos cada vez más presentes en la ordenación forestal, y en las distintas figuras de ordenación territorial y planeamiento sectorial. En España, hasta la fecha, la normativa e instrumentos de ordenación territorial, de concepción sesgadamente urbanística, han resultado muy poco aplicables a lo...
Article
There is an increasing demand for tools that support land use planning processes, particularly the design of zoning maps, which is one of the most complex tasks in the field. In this task, different land use categories need to be allocated according to multiple criteria. The problem can be formalized in terms of a multiobjective problem. This paper...

Los cambios tecnológicos y socioeconómicos que han tenido lugar a lo largo del siglo 20, han inducido una serie de dinámicas de expansión urbana que han dado como resultado procesos de suburbanización y patrones de crecimiento urbano disperso. En los últimos años ha surgido un debate sobre los aspectos negativos de este tipo de patrones de crecimie...

Cellular automata CA stand out among the most commonly used urban models for the simulation and analysis of urban growth because of their ability to reproduce complex dynamics, similar to those found in real cities, from simple rules. However, CA models still have to overcome some shortcomings related to their flexibility and difficult calibration....
Article
Why do societies implement land policies? A number of arguments have been put forward in the literature, ranging from economic conceptions based on market failure and the problem of negative externalities to a more social conception based on welfare distribution and collaborative planning. However, neither all societies with similar market failures...

In this paper we present a Population-Based Iterated Greedy (PBIG) algorithm for delimiting and zoning rural settlements. Each cadastral plots is allocated to a category (traditional–historical, common or none) considering restrictions such as the characteristics of the existing edifications and the building density. Since the problem has multiple...

Obtaining information on the distribution of rural landscape types is an active research topic within Spanish rural studies. This paper presents a new hierarchical object-based classification method for the automatic detection of various land use classes in a rural area, combining lidar data and aerial images. In view of the upcoming availability o...
Article
Full-text available
Object-oriented classification of high spatial resolution imagery usually offers higher accuracy than traditional per-pixel approaches, as real-world features (objects) appear in those as groups of pixels with a relatively high internal variability – though generally lower than that of the whole image – due to the heterogeneous spectral response of...

The environmental, cultural and economic consequences of land use change, including abandonment of agricultural use, have been recognized for a long time. It has often been assumed that the transformations of the agricultural systems in developed countries (and particularly in Europe) took place, for the main part, in the immediate years after the...

RESUMEN: El valor de la tierra es una variable difícil de determinar, debido no solamente a factores no visibles pero presentes en el proceso de transacción, sino también a las características locales que influyen sobre la formación del precio. Las particularidades a nivel local no siempre afectan de la misma manera al valor de las tierras, por lo...
Article
In recent years, cellular automata (CA) models for urban growth simulation have proliferated because of their simplicity, flexibility and intuitiveness, and particularly because of their ability to incorporate the spatial and temporal dimensions of the processes. Though apparently simple, CA models are capable of modeling complex dynamic systems su...
Article
Land fragmentation can be an important drawback for the development of rural areas. Due to the small size of the units, land management and planning are difficult from both the private and the public point of view. In some regions of Europe, land fragmentation can lead to the collapse of land-based activities such as agriculture and forestry. This...
