PYL

General System description

System name: Pimp your landscape

Acronym: PYL

Brief overview

PYL is a cellular automaton based software, which supports the assessment of the impact of land-use management decisions on ecosystem services on regional scale. This includes land-cover changes, changes in sectoral land-use management practices and the establishment of linear and point-shaped infrastructural elements with defined impact area. Target group of the support system are planners on regional and municipal scale.

Scope of the system

PYL allows the decision maker to capture existing knowledge on the impact of single land-use types (and the management practices within the land-use type) and infrastructural elements to assess the relative benefit of planning alternatives for a set of selected (by the planner) ecosystem services. The cellular automaton technique supports the integration of existing knowledge on the mutual impact of neighbouring land-use types and the definition of rules describing the impact of (actual and future) environmental and social parameters on (i) on ability of a land-use type or management practice to contribute to the provision of ecosystem services and (ii) on the probability of a transformation of a land-use type into another.

System origin

PYL is developed since 2007 in a cooperation of TU Dresden, Chair for Soil Science and Soil Protection (scientific concept) and PiSolution GmbH (Programming, Software Architecture). The software started with supporting participatory planning processes in the Euro-Region Neisse in the Frame of the Interreg-III-a project IT-Reg-EU and was then widened to support regional planning in the frame of the projects ENFORCHANGE and REGKLAM (German Federal Ministry of Education and Research). Furthermore, a more simple version of the software is used in environmental education at school level (DBU project KIDS) and in the frame of e-Learning (Leonardo da Vinci activity TrainForEducation). PYL is a semi-commercial product, as its further development is mostly done within R&D projects, while interrim versions are yet in test and use. For scientific purposes (R&D cooperations), the use is for free. For the use in practice (planning support and environmental education, a commercial software licence is available. Actually, an interdisciplinary team of 8 scientists (TUD) and 3 software engineers (PiSolution) develops the software for the application in assessing regional climate change mitigation strategies in land-use in Saxony (REGKLAM, MORO project Klimafit), testing alternatives for open-cast mining areas restoration in Saxony (regional planning association Western Saxony), deriving optimized strategies for catchment area management in Brazil (IWAS, German Federal Ministry of Education and Research / EMBRAPA).

Support for specific issues

Is the system designed to take into account specific uses? E.g. guidance on ways to characterize biodiversity, economic-biodiversity tradeoff analysis methods, risk assessment methods, landscape analysis methods, timber harvest effects, climate change effects, biological effects (pests, pathogens, invasives), fire,...

Support for specific thematic areas of a problem type
