This paper reports on research to evaluate the potential of Original Texas Land Survey (OTLS) to generate information that can be used to quantitatively map historical vegetation cover and analyse pertinent aspects of vegetation ecology. Research was conducted in Brazos County in east-central Texas. OTLS data are easy to acquire and convert to geo-referenced autecological information.

This paper analyzes and quantifies the land use/land cover changes of the main forest and semi-natural landscape types in Sicily between 1955 and 2012. We analyzed seven representative forest and shrubland landscapes in Sicily. These study areas were chosen for their importance in the Sicilian forest panorama. We carried out a diachronic survey on historical and current aerial photos; all the aerial images used to survey the land use/land cover changes were digitalized and georeferenced in the UTM WGS84 system.

Abstract:

Classification Concepts The FAO Land Cover Classification System software is due to be released in its third version, and with it come four supporting volumes. The first of these is Classification Concepts, which lays the foundation for an understanding of the Land Cover Metalanguage (LCML) that is used to create classes for legends.

Classification Concepts The FAO Land Cover Classification System software is due to be released in its third version, and with it come four supporting volumes. The second volume is the User Manual which is a practical guide to all the features of the software version 3, with examples of how to make various types of classes e.g. for distinguishing managed and non-managed forest.

Advanced Database Gateway The FAO Land Cover Classification System software is due to be released in its third version, and with it come four supporting volumes. The third volume is a tutorial for the use of the Advanced Database Gateway which allows users to better interact with the LCCS and adapt it to their needs. The FAO LCCS is applicable to commercial use, national security, environmental protection, natural resource management, climate change mitigation and tracking of greenhouse gas emissions; and creates land classifications that are internationally transparent and comparable.

Las características espaciales de las ciudades resultan decisivas en los principales problemas urbanos: la calidad de vida, la movilidad, el consumo energético y de materiales, etcétera. Para describir el crecimiento de las ciudades, la compacidad y la densidad se han convertido en dos de los valores más funcionales, y pueden ser calculados a través de las principales bases de datos de coberturas del suelo en España: corme Land Cover y siose.

En este número sobre suelos hemos planteado una serie de preguntas clave: ¿debe extenderse o comprimirse el suelo urbano? ¿Quién asume los costos y quién recibe las ganancias? ¿Contribuye esa respuesta a la igualdad entre los habitantes de la ciudad? Las respuestas aquí presentadas evidencian que la noción de ‘suelo urbano’ es un territorio en disputa donde el punto de vista si importa pues tiene, literalmente, consecuencias de escala urbana.

Over the past 20 years, the term "agro-ecological zones methodology," or AEZ, has become widely used. However, it has been associated with a wide range of different activities that are often related yet quite different in scope and objectives. FAO and IIASA differentiate the AEZ methodology in the following activities:

The Global Forest Resources Assessment 2015 (FRA 2015) development began in June 2011 when the FRA Advisory Group discussed the FRA Long-Term Strategy and its implications for FRA 2015. The design process involved users, national correspondents and experts from a wide variety of technical backgrounds.
