A klíma gyors változása az erdőgazdálkodás számára nagy kihívás a hosszú termesztési ciklus miatt. Mára a korábban változatlannak tekintett termőhelyi potenciált dinamikusan változó tényezőként kezeli az erdőtervezés. Az Agrárklíma döntéstámogató rendszer (DTR) ehhez nyújt háttérinformációt. Az előrevetítési időszak választható és a század végéig t...

Mortality appeared in a relict Scots pine (Pinus sylvestris L.) forest where the sandy pine forest association (Pinetum-Festuco vaginatae sylvestris) is unique in the Carpathian Basin. To identify the complex causes of tree mortality, we analysed the climatic and soil conditions completed with bryological and biotical (pests) surveys. Altogether th...

PSD (particle size distribution) is a key factor affecting soil hydro-physical properties (e.g. hydraulic conductivity and water retention), which makes its determination essential. Climate change increases the importance of water retention and permeability as extreme weather events can severely impair the water supply of drought-sensitive vegetati...

The paper investigates the reference corpus of a climate change contrarian report. We categorized the journal abstracts according to the endorsement positions on anthropogenic climate change. These results were contrasted by an in-text citation analysis. We focused here on the role of the papers included by the report editors concerning the mainstr...

Landscape Protected Area of Sopron-mts. - Monographic studies of the natural and cultural values of the Sopron-mountains

Climate change particularly threatens the xeric limits of temperate-continental forests. In Hungary, annual temperatures have increased by 1.2 °C-1.8 °C in the last 30 years and the frequency of extreme droughts has grown. With the aim to gain stand-level prospects of sustainability, we have used local forest site variables to identify and project...

This paper analyses the recent recurring dieback and growth decline of Black pine (P. nigra Arn. var austriaca) in the Keszthely mountains of south-west Hungary, and their relations to water deficits due to droughts. These relations were studied in five stands with low soil water storage capacity for the period 1981–2016. The vitality was assessed...

In this paper, a novel decision support system (DSS) will be introduced, based on geospatial data analyses that we developed for the Hungarian forestry and agricultural sectors. This work was part of a larger research project, whose goal is to evaluate the impacts of projected climate change on forestry and agriculture and to identify potential ada...

Akác faanyagot gőzöltünk, hogy a sötét egzóta faanyagokhoz hasonló színeket kapjunk. A barna színárnyalatok széles skálája hozható létre az akác faanyag gőzölésekor. Megállapítottuk, hogy ezek a színárnyalatok ugyanazt a benyomást keltik, mint a sötét egzóta faanyagok, függetlenül attól, hogy közel vannak-e valamelyik egzóta fafaj színéhez. Néhány...

Research of future climate tendencies is a precondition for appropriate climate change adaptation strategies in forestry and agriculture. The aim of this paper is to investigate the expected probability and magnitude of threatening climate conditions that are of primary importance in terms of forest management. Until 2100, precipitation and tempera...

The Technical University of Madrid (UPM), as a European project leader university, has developed a series of international actions to address the new challenges appearing in the European Higher Education Area (EHEA) through the internationalization processes in higher education, society and economy. Five Erasmus actions have been developed in the l...

The United Nations Climate Change Conference, Durban 2011, delivered a breakthrough on the international community’s response to climate change. In the second largest meeting of its kind, the negotiations advanced, in a balanced fashion, the implementation of the Convention and the Kyoto Protocol, the Bali Action Plan, and the Cancun Agreements. Th...

Climate change is expected to have severe impacts in the forestry sector, especially in low-elevation regions in Southeast Europe, where forests are vulnerable and sensitive to the increasing probability and severity of climatic extremes, especially to droughts. For providing information about the most important regional and local risks and mitigat...

The potential distribution and composition rate of beech, sessile oak and Turkey oak were investigated for present and future climates (2036-2065 and 2071-2100) in Hungary. Membership functions were defined using the current composition rate (percentage of cover in forest compartments) of the tree species and the long-term climate expressed by the...

• Background and aims: Rainfed sectors of agriculture such as nature-close forestry, non-irrigated agriculture and animal husbandry on nature-close pastures are threatened by projected climate change especially in low-elevation regions in Southeast Europe, where precipitation is the limiting factor of production and ecosystem stability. Therefore t...

According to the climate predictions, hydro-meteorological conditions expected to change in the future, leading to the alteration of erosion dynamics. Based on regional climate projections, climatic extremes may become more frequent for the end of the 21st century. Intensive rainfall events may increase soil loss on the sloping areas resulting in p...

Regional climate change projections show a changing climate in the metropolitan region of Hamburg for the end of the century: The temperature could increase and the precipitation in summer could decrease. To cope with the probably longer lasting and hotter summer conditions in Europe there are different possible adaptation measures in land manageme...

Background A regional-scale sensitivity study has been carried out to investigate the climatic effects of forest cover change in Europe. Applying REMO (regional climate model of the Max Planck Institute for Meteorology), the projected temperature and precipitation tendencies have been analysed for summer, based on the results of the A2 IPCC-SRES em...

A regional-scale case study has been carried out to assess the possible climatic benefits of forest cover increase in Europe. For the end of the 21st century (2071-2090) it has been investigated, whether the projected climate change could be reduced assuming potential afforestation of the continent. The magnitude of the biogeophysical effects of en...

In whole Central Europe agricultural production is highly vulnerable and sensitive to impacts of projected climatic changes. The low-elevation regions of the Carpathian Basin (most of the territory of Hungary), where precipitation is the minimum factor of production, are especially exposed to climatic extremes, especially to droughts. Rainfed agric...

Climatic effects of forest cover change have been investigated for Hungary. For the time period 2071–100 we have analyzed whether the climate change signal for summer precipitation and the probability of droughts can be reduced assuming maximal afforestation for the entire country (forests covering all vegetated areas). The biogeophysical effects o...

Climatic effects of forest cover change have been investigated for Hungary applying the regional climate model REMO. For the end of the 21st century (2071–2100) case studies have been analyzed assuming maximal afforestation (forests covering all vegetated area) and complete deforestation (forests replaced by grasslands) of the country. For 2021–202...

Land surface plays a key role in a climate system. Thus, the land surface description will become increasingly important for climate modelling by its feedbacks on the climate. Various forms of active/passive remotely sensed data are nowadays being used to provide continuous and up-to-date information on the earth’s surface on both global and region...

Natural vegetation is a dynamic component of the climate system, which plays a key role in determination of weather and climate. Forests, due to their higher leaf area, larger roughness length, lower albedo and deeper roots compared to other vegetated surfaces affect the exchange of water- energy- and momentum with the atmosphere. Thus climatic fee...

In the NEESPI Regional Focus Research Centre for Non-boreal Eastern Europe, Sopron, researches are focusing on the climatic tolerance and distribution of zonal tree species at the xeric forest limits. These limits at the planar border zone between closed forest and woodlands (forest steppe) are determined primarily by climatic aridity and are espec...

The aim of this study is to provide quantitative information on the effect of climatic change on the growth and vitality of European beech: although the species is considered in its optimum highly plastic and adaptable, it becomes climate-sensitive closer to its xeric (lower) distribution limits. The future of beech in Southeast Europe requires spe...

In Southeast Europe, warming and drying of summers are stronger than the global trends. In Hungary a significant increase in drought frequency started during the second half of the 20th century. Regional impact studies show that recurrent droughts can cause growth decline and mortality of zonal forests at their lower limit of distribution. This red...

In the leaf extracts of two plant species (Quercus robur L. and Phaseolus vulgaris L.), peroxidase (POD) and polyphenol oxidase (PPO) activities have been measured by the methods of Shannon et al (1966) and Flurkey and Jen (1978). The oxidative activities regarded as semi-empirical biochemical variables have distributions in the plant foliage and b...

Dry years and dry summers in Hungary have been analyzed using the regional climate model REMO for the time periods 1961–2000 and 2001–2100. Dry periods were determined and classified by intensity, considering modeled and observed precipitation and temperature data. The intensity of dry events was defined according to the negative precipitation devi...
