In the evaluation of the onset, severity and duration of situations of water stress and droughts, indicators based on processes with intensive use of remote sensing can be used. In the monitoring of agricultural activities as well as the management of water and forest resources, spatio-temporal distributions of information of actual evapotranspiration (ETact) are crucial. This work presents the theoretical aspects of spatio- temporal assessment of ETact process, from remote sensing and meteorological data.

The analysis of evaluable information on degradation and dangerous natural processes at the agricultural lands on Asian territory of the Russian Federation (according to the data of 1991-2015) was done. The natural processes negatively affecting the soil (available land) are divided into groups according to their hazard extent: a) processes oriented to destroy the soils and lands, b) processes changing the soil cover pattern and leading to degradation of soils and decreasing their fertility

Linear models were used to investigate the relationship between vegetation tiers (altitudinal vegetation zones) and variables derived from a digital elevation model - elevation and potential global radiation. The model was based on a sample of 138 plots located from the 2nd to the 5th vegetation tier. Potential global radiation was computed in r.sun module in geographic information system GRASS. The final model explained 84% of data variability and employed variables were found to be sufficient for modelling vegetation tiers in the study area.

In this research, we propose a method for describing rural landscapes in peri urban areas and evaluating their impact on house and land prices. This method matches quantitative geography and econometric methods used for hedonic analysis. A geographical model is used for producing variables describing the landscape an observer can look at when located in a specific house or a land parcel. This model takes account of these parts of the landscape that are hidden by houses, buildings, hills, forests,. . .

Land use reflects the needs, demands and values of human society. We can see two antagonistic trends of land use change in Slovakia over the past few decades. Land use change towards more intensive in some areas (vicinity of cities, highways, lowlands), but others (uplands and mountains with traditionally agricultural used) are abandoned and left to their own spontaneous dynamic. The abandonment of agriculture is a pattern common to all industrialized countries, especially in hilly and mountain ranges (Farina, A., 2007).

The Coteaux de Gascogne region, an upland area in south-western France, is a site where studies related to the future of landscapes and the sustainability of natural resource management are well documented. The local agricultural system is induced by a “house centred” society with the particularity of passing on the inheritance and farm estate identically from one generation to the next. This system generates a mosaic landscape made up of field crops, grasslands and woodlots.

The effective use of natural resources is one of the important issues of today. GIS is recently used as an effective tool for solution of complicated problems. Land use researches in landscape planning studies can be done reliably and practically by the use of GIS. Depending on the increase of demands on coastal zones, the determination of land uses and conservation of them gets more important today. Within this context, in this study, the past and the present land uses of Tekirdağ coastal zone is pointed out.

Development of a cartographic mdel for the forest site types delineation in the Belgian Ardenne. The paper presents an original method dealing with the forest site types delineation. The suggested method consists in integrating a typological key in a GIS aiming at producing a thematic map that describes forest site types. Data used are the soil map of Belgium (digitized at the scale 1:20,000) and a digital elevation model built from a topographic map (scale 1:10,000). The typological key is mainly based on the methodology used by Thill et al.

En los últimos años han sido incuantificables las aplicaciones que se han llevado a cabo mediante la utilización de las denominadas Tecnologías de la Información Geográfica, bien a través del empleo de los sistemas de información geográfica (SIG), bien mediante el manejo y el análisis de imágenes de satélite (Teledetección), o bien mediante la aplicación de técnicas estadísticas de análisis multivariantes.

The paper presents the spatial distribution of ecological suitability for grape growing in Bucium vineyard (Romania), viticultural area with ecological characteristics representative for northern vineyards. The study is based on a complex methodology implying use of remote sensing, Geographical Information Systhems (GIS), climatic data, topographic and pedologic maps. Research reveal the low ecological potential of Bucium area, specialized, traditionally, in white table wines, sparkling wines and white quality wines.

Urban green areas are important sites established for recreational, ecological, and aesthetical purposes. Urban green areas are different form the other green space usage, can be used by the all parts of the community. Public green space standards, construction law No. 3194 of the plan to be built on the basis of 10 m² per person in the regulations "active green space" is defined as. About the amount of green space in the regulation applies to active green space. Active green space are defined parks, children's playground and play areas.
