FORECOM: Forest cover changes in mountainous regions – drivers, trajectories and implications

Research project supported by the Swiss Cooperation Programme of the new member states of the European Union
date: 2012-2016
project leader: Jacek Kozak
research team from IG&SM: Joanna Depta, Dominik Kaim, Natalia Kolecka, Małgorzata Luc, Krzysztof Ostafin, Katarzyna Ostapowicz, Aneta Szablowska-Midor, Mateusz Troll, Zbigniew Ustrnul, Agnieszka Wypych

Collaborator: the Swiss Federal Research Institute for Forest, Snow and Landscape Research WSL

The FORECOM project aims to improve understanding of past, present and future forest cover changes in the Swiss Alps and the Polish Carpathians in the context of land use and climate changes. In the project we plan first to identify trends in forest cover change over the past 150 years for the Polish Carpathians and the Swiss Alps. Then we intend to quantify relative contributions of climate and land use to the past forest cover change and to develop combined climate and land use change scenarios for projecting future forest cover change. Our final goal is to assess important implications of forest cover change: potential impacts on biodiversity and trends in forest carbon pools, adding in this way to the current debates on human drivers of the global climate change.

To reach the project objectives we intend to work extensively with historical maps available both for the Swiss Alps and the Polish Carpathians since the 19th century; additionally, we plan to use aerial photos, high resolution satellite imagery and airborne laser scanning data. Spatially explicit models will be constructed on a basis of available data integrated and processed by means of geographic information systems. An important technology-oriented aspect of the project will be the development of robust methodologies and tools to capture, integrate and process cartographic and earth observation data.

Expected results of the project are long-term and large scale reconstructions of historical forest cover dynamics for the Swiss Alps and the Polish Carpathians, quantification of relative effects of climate and land use change on forest cover change, improved models allowing predictions of forest cover change under various land use / climate change scenarios, and assessments of important consequences of forest cover change.

LIM: Integration of categorical- and gradient-based approaches in landscape fragmentation and connectivity modelling using GIS&T (2011/03/D/ST10/05568)

Research project supported by the National Science Centre
date: 2012-2015
project leader: Katarzyna Ostapowicz

researcher: Elżbieta Ziółkowska

Landscape spatial structure analysis and modelling are crucial for understanding the underlying ecological processes and their dynamics. Most of quantitative methods which are used in modern landscape ecology to quantify landscape spatial structure and to assess landscape/habitat fragmentation and connectivity, are based on categorical (discrete) representation of landscape heterogeneity (mainly patch-based models). However, categorization (which is often subjective) obscures all internal heterogeneity of discrete landscape structures and could lead to losses of important ecological information. Therefore, currently an emerging issue in landscape and ecological studies is an alternative representation of landscape spatial pattern - landscape gradient (continuous) models. They are assumed to accurately represent continuous spatial heterogeneity, in this way helping for better understanding of pattern-process relationships. The integration of these two different approaches into one coherent model could even more increase accuracy of landscape structure representation and then assessment of landscape fragmentation and connectivity, crucial in ecological and biodiversity studies. 
The aim of this project is development of new approaches allowing to integrate categorical- and gradient-based landscape models for more accurate representation of landscape structure (Landscape Integrated Models - LIM) and based on that - a comprehensive description (quantitative and qualitative) of landscape/habitat fragmentation and connectivity. Within the project a collection of new methods and metrics allowing for better assessment of landscape/habitat fragmentation and connectivity will be developed.

 

200 years of land use and land cover changes and their driving forces in the Carpathian Basin

Research project supported by NASA
date: 2011-2014
project leader in the IG&SM: Jacek Kozak
research team from IG&SM: Dominik Kaim, Małgorzata Luc, Krzysztof Ostafin, Katarzyna Ostapowicz, Mateusz Troll

project leader: University Wisconsin-Madison
collaborators: University of West Hungary, Sopron, Hungary; Institute of Landscape Ecology, Slovak Academy of Sciences Branch Nitra, Nitra, Slovakia; Leibniz Institute of Agricultural Development in Central and Eastern Europe (IAMO), Halle (Saale), Germany; Swiss Federal Institute for Forest, Snow and Landscape Research, Birmensdorf, Switzerland; Department of Geography, Humboldt-University at Berlin, Berlin, Germany

The aim of the project is to study long-term agricultural change in the Carpathian Basin (i.e., the Pannonian Plain and the Carpathian Mountains) in Central and Eastern Europe, a region that has been dominated by agriculture for centuries and that has experienced several major socio-economic transformations during the 19th and 20th centuries (i.e., World War I and the demise of the Austro-Hungarian Monarchy; World War II; the rise and fall of socialism; and the eastward expansion of the European Union). These socio-economic transformations have triggered drastic land use change, rendering the region a hotspot of agricultural land use change. We will improve understanding of patterns of agricultural LCLUC in a rapidly transforming region and we will provide novel insights into dynamics of agricultural land use systems in response to major shifts in institutional, economic and societal conditions. Our overarching goal is to quantify long-term and recent agricultural land cover and land use change (LCLUC) in the Carpathian Basin and to understand its underlying causes. These analyses will provide a better understanding of how socioeconomic shocks and rapid institutional transformation affect agricultural land use systems, and will substantially improve knowledge about non-linearities and tipping points in land use transitions.
To advance land use science and our understanding of land use transitions, our proposed project has three major goals:

  • first to improve knowledge about long-term agricultural land use change in regions with long land use legacies,
  • second to quantify rates and patterns of agricultural land use change in response to drastic economic and institutional transformations (i.e., the breakdown of socialism and the EU expansion)
  • third, to build understanding of the drivers of agricultural land use change and the relative importance of past land use legacies for determining current land use change.

Land cover changes in the Beskid Sadecki – analysis of ground-based repeat photography
project leader: Dominik Kaim

The use of traditional, terrestrial photography enables conducting land use and land cover research of much longer periods than aerial or satellite images. The integration of archival photography with other remote sensing data and digital elevation models gives a possibility to study land use transitions over the years, maintaining a greater accuracy than in case of the archival cartographic materials. In contrast to the maps, photographs are also a source of raw data, which also makes them attractive as primary research material. What's more, the historical ground-based images are relatively easily accessible and cheap data source. Their great advantage, acting undoubted advantage over aerial or satellite images is the fact that it can be easily understanding by non-specialists, what allows a much wider use. The project focuses on the analysis of changes in land cover and land use in the vicinity of Krynica. As an important center of tourism in the Carpathians in the past and nowadays it offers an easy access to archival photo resources.
