The aim of the project is to construct a spatially explicit model of land use and land cover changes in the Polish Carpathians until 2050. The model will take into account both biophysical and socio-economical factors influencing land use directions. In addition it will allow to develop and test various scenarios of land use change in the study area.
In the study various available data will used: national census data, archive and contemporary maps, remotely sensed data (aerial photos, satellite images, elevation models). The model of future land use will be based on the contemporary land use and land cover in the Polish Carpathians, directions of past changes and confirmed relations between biophysical and socio-economic factors and past land use and land cover changes. The model will use geographic cellular automata which enable spatially explicit modeling of land use and land cover changes.
Planned outcomes of the project are geographic data bases for the Polish Carpathians, satellite land use and land cover maps of the study area for the 1980s and 2005-7 and the validated model of future land use.

In the last decades one can observe deep changes in land management all over the world. The changes are caused by a group of two factors: external - connected with civilization, and internal one - triggered off by disturbances between particular elements of geographical environment. A number of essential changes in use of geographical environment can also be observed in Carpathian Mts. in Poland since the 80s of the 20th century. A land use is one of the most synthetic factors, that enables the analysis of geographical environment transformation. The analysis of reasons of land use changes and determination of the trends and their consequences to environment can allow to work out methods and a modus operandi to arrange environment in order to mitigate unprofitable changes. Such investigation have been carried out in analysis of relationship between land use and climate, in assessment of biological diversity and sustainable development of environment and its protection from the climate changes point of view.
The survey area encompasses piedmont and highlands - an ecosystem of above-regional importance. The way of resources management in highlands, and especially on the slopes has a direct influence on magnitude of mass movement and soil cover degradation. The activities of local communities based on forest and agricultural forms of land use until recently. Changes of these activities have serious consequences in various fields of economy. Results of the investigation should have notable practical effects. They should be an important basis of various programs connected with management and protection of environment and determination of the areas sensitive to degradation. Improvement of soils, flood prevention, mitigation of the damages caused by floods, limitation of conflicts in land use, prevention of dividing up of land as well as many other environmental, social and economic problems would be possible to accomplish on the basis of the project results.
Satellite images acquired in 2006 will be used in the project due to extensive surface area under investigation. The results of interpretation of these images will be compared with a ground survey conducted at the end of the 80s of the 20th century. Moreover, to assess the influence of the relief on land use changes Numerical Terrain Model based on SRTM data will be applied.

Clouds, depending on genera, cool or warm the atmosphere. The warming effect is a consequence of absorbed infrared radiation, while cooling results from a significant cloud top albedo that reflects incoming solar shortwave radiation. It is estimated that 1% increase in the global albedo would rise average temperature of the atmosphere by 0.5K. Since the clouds control primarily a value of planetary albedo, accurate information on a total cloud amount becomes crucial issue for the climate change studies.
Typical source of cloud data are surface-based observations, which are subjective estimation of a sky fraction covered by clouds. This observations are performed manually by meteorologist at synoptical stations since centuries. However, areas with high population density are privileged, while oceans, deserts and icefields of Antarctica or Greenland lack of any cloud information. Since '80 of last century, satellite observations serve as an alternative. Quality of satellite data depends on sensor's specification. Moderate Resolution Imaging Spectroradiometer (MODIS) is considered as the most advanced for cloud studies on a global scale. MODIS are a twin scanning radiometers onboard NASA's Terra and Aqua polar orbiting platforms.
The goal of this Project is to validate MODIS total cloud amount data with surface based observations. The comparison will reveal the factors (i.e. atmospheric conditions, viewing geometry) that influence differences between satellite and surface-based cloud amount. Study will cover years 2003-2007, that is over 7000 MODIS passes over area of study or over 100000 individual cloud amount estimations. As an area of study the territory of Poland was chosen, as a representative for moderate climate zone. The results of the project allow for evaluation of MODIS data as a source for cloud climatology. By comparing differenced obtained for MODIS-surface comparison with analogical results already calculated for other sensors, it will be possible to find out if MODIS data are the closest to 'real cloud amount' as estimated by surface observers.

The aim of the project was to define the constraints and driving factors of spatial distribution and changes of land use and land cover in mountain areas. The research focused on distribution and changes of forest cover, related to human impact. Forest cover and its changes were assumed to represent the varying in time intensities of land use by mountain populations. The analysis of forest cover was carried on in relation to elevation, vertical gradients in mountain environment and vertical economy systems developed in mountain areas.
In the first stage of research, a comparative studies of selected mountain ranges were carried on. Spatial databases for sections of the Himalayas, Caucasus, Elburs, Pyrenees, Alps, Apennines, Andes, Cordilleras, Appalachians and Carpathians were created. Databases contained following thematic layers: land cover and land use, elevation and, for part of the regions studied, population. They allowed to construct models of relations of land use - population density and forest proportion - relief.
In the second stage of the project studies of land cover change in selected regions of the Polish Carpathians were carried on. Spatial databases for the Polish Orawa region, for a section of the Western Beskidy Mts. and southern Małopolska were created. Databases consisted of land use and land cover datasets for several time profiles and of elevation data. They allowed to analyse changes of forest cover in relation to mountain relief. Rapid decline of agricultural land use in upper part of the mountains and on steep slopes was observed. It was related to the social and economic transformation of the mountain area, occurring under external influences.
Changes of forest cover in the Polish Carapthians were discussed in the context of the forest transition model and on a basis of comparative research of mountain areas carried on in the first stage of the project. One of the outcomes of the comparative research will be the land use and land cover change scenario for the Carpathians (currently in preparation).
In the project, several methodological results were achieved. A methodology of land use and land cover change studies using different materials (historical maps, contemporary maps, air photos, satellite imagery) was established. Specifically, methodological issues related to use of available global datasets in land use and land cover change research were studied in depth.
