Drivers of grassland loss in Hungary during the post-socialist transformation (1987–1999)

The increase in the speed of land-cover change experienced worldwide is becoming a growing concern. Major socio-economic transitions, such as the breakdown of socialism in Europe, may lead to particularly high rates of landscape transformations. In this paper we examined the loss of semi-natural grasslands in Hungary between 1987 and 1999. We studied the relationship between 9 potential driving forces and the fate of grasslands using logistic GLMs. Grassland loss was found to be very high (1.31 % per year), which is far higher than either before or after this period. The most influential predictors of grassland loss were environmental and landscape characteristics (soil type, area of remnant grassland patches), and the socio-economic context (distance to paved road, and nearest settlement, human population density). Several processes and relationships can only be understood from a historical perspective (e.g. large extent of afforestation, strong decrease of soil water table). Grassland loss during the study period emerged as a consequence of survival strategies of individual farmers seeking adaptation to the changing environmental and socio-economic conditions, and not urbanization and agricultural intensification which are the main underlying drivers for the ongoing landscape transformations in most parts of the developed world. Though globalization increasingly influences local land use decisions , reconstructing and modelling recent landscape changes cannot be done without a proper understanding of local history and culture. Our analysis shows the importance of large-area yet high resolution landscape change research, which may reveal unexpected patterns of land cover change, undetected at coarser scales

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the 21st century

During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental changes that can have global consequences. The Northern Eurasia Future Initiative (NEFI) has been designed as an essential continuation of the Northern Eurasia Earth Science Partnership Initiative (NEESPI), which was launched in 2004. NEESPI sought to elucidate all aspects of ongoing environmental change, to inform societies and, thus, to better prepare societies for future developments. A key principle of NEFI is that these developments must now be secured through science-based strategies co-designed with regional decision makers to lead their societies to prosperity in the face of environmental and institutional challenges. NEESPI scientific research, data, and models have created a solid knowledge base to support the NEFI program. This paper presents the NEFI research vision consensus based on that knowledge. It provides the reader with samples of recent accomplishments in regional studies and formulates new NEFI science questions. To address these questions, nine research foci are identified and their selections are briefly justified. These foci include: warming of the Arctic; changing frequency, pattern, and intensity of extreme and inclement environmental conditions; retreat of the cryosphere; changes in terrestrial water cycles; changes in the biosphere; pressures on land-use; changes in infrastructure; societal actions in response to environmental change; and quantification of Northern Eurasia's role in the global Earth system. Powerful feedbacks between the Earth and human systems in Northern Eurasia (e.g., mega-fires, droughts, depletion of the cryosphere essential for water supply, retreat of sea ice) result from past and current human activities (e.g., large scale water withdrawals, land use and governance change) and potentially restrict or provide new opportunities for future human activities. Therefore, we propose that Integrated Assessment Models are needed as the final stage of global change assessment. The overarching goal of this NEFI modeling effort will enable evaluation of economic decisions in response to changing environmental conditions and justification of mitigation and adaptation efforts

Concepts and delimitation of the worldʼs macro-regions

The authors focus on the current differentiation of the world and on its cognitive, application and educational frameworks and importance for the present. Macro-regional differentiation of the world has resulted from geographic concepts and it is a foundation for understanding the global development of society. This article evaluates the specific concepts and factors that form concepts of world macro-regions prepared by famous authors. It also presents a methodological approach for macro-regional forming of the world. After a theoretical and methodological introduction there is a discussion of the differentiation of the world entitled “Macroregional differentiation of the world - formation and application.ˮ The authors also present their conception of world differentiation and evaluation of the creation macro-regions and their positive and negative influence of the macro-regional differentiation of the world

Macro-regional differentiation of the world: Authors' concept and its application

This article is a continuation of the same authors' study entitled 'Concepts And Delimitation Of The World's Macro-Regions' prepared for the 1/2018 of this journal (Anděl et al. 2018). The main aim of the first part was an evaluation of the concepts and factors which have been used as a basis for the delimitation of the different macro-regions of the world. In this second part, the authors propose their own macro-regionalisation of the world this is a combination of four concepts, with relatively different contents: those of De Blij and Muller (1997), Cole (1996), Huntington (1996) and Hampl (2009). This macro-regionalisation arises from sociocultural affiliation, economic interrelationships and territorial continuity. Along with the concept of the macro-regional differentiation of the world itself, we focus on evaluating the importance of the shaping of macro-regions, as well as assessing the positive and negative features of individual concepts and their influence on the macro-regional differentiation of the world
