The Author discusses the present state of Polish geography against the background of the traditional position, and the rapid development taking place after the Second World War. The introduction of new methods and new directions, as well as new organization are considered to have been reflected in the rising international position of Polish geography. Further topics here include the relationship between physical and human geography, the growing de facto separation of these two branches, and the development of several independent sciences rooted in geography but now existing apart from it (like geomorphology, climatology, hydrology, etc. on the physical geography side, with the element of the environment as a subject of study). On the other hand, social economic geography examines the effects of human activity in the environment, thereby synthesizing spatial management and bridging the gap between the earth sciences, the economy and the social sciences. The degradation of environmental resources, explosion of the human population and climate change have all forced geography (and other sciences) to head in the global direction, as well as towards interdisciplinary cooperation, likewise on the level of the world as a whole. If we are to meet the challenges this all entails, we will need to think about creating interdisciplinary problem teams, as well as activating existing organisational structures in science (notably the geographical sciences), with full benefit taken from research centres that run studies on differing spatial scales, in conjunction with international global programmes like the Future Earth. The geography of the future should not be a closed science, but should draw on the knowledge of scholars of various specialisations, seeking environmental solutions that require intervention on both the global and regional scales. Polish geography should participate in this activity, inter alia as part of Future Earth, as a new venture. It can also be regarded as our task to ensure that society is aware of all the above issues.

Science at the state level consists of two distinct and heterogeneous systems: the global science system and national science systems. National science systems are deeply embedded in global science, and states seek to use global knowledge for domestic economic needs. However, harnessing the wealth of global knowledge can only be done through scientists. Consequently, the scientific strength of states in practice depends on the scientific strength of individual scientists. Their ability to collaborate internationally and to tap into the global scientific network is crucial. By remaining outside it and working within local research programs, the academic community risks being marginalized, losing the interest of national research funding patrons, and losing the ability to influence the development of science.

In this text, we analyze the limitations of using academic age as a proxy for biological age in the whole national science system, for which we consider both biological age and academic age of all researchers from all Polish universities, holding at least a PhD degree and participating in global academic science through international publications (N = 20 569). An approximation of a researcher's functioning in global science is having at least one publication indexed in the Scopus database in the analyzed decade 2009–2018. Thus, using the example of comprehensive data from the entire national system of science, we estimate the extent of limitations of using academic age as a proxy for biological age depending on selected independent variables and analyze both the practical and methodological implications of using academic age in academic career research, which is one of the most important components of quantitative studies of science.

This study presents an analysis of the unprecedented growth of international research collaboration in Europe in terms of distribution of co-authorship and citation of globally indexed publications over the last decade (2009–2018). The dynamics of change that emerge from this analysis are as follows: the increasing level of international cooperation is drawing key European systems away from institutional cooperation, with stable and strong national cooperation. National scientific output, i.e. the total number of publications, remains stable, and the entire increase in the number of publications over the period should be attributed to international co-authorship publications, which are the only driving force behind the increase in the number of publications in Europe. Due to the emergence of global networked science, in which the role of national policies in cooperation is decreasing and the role of scientists is growing, the key to the development of cooperation in Europe (and in Poland) is the readiness of individual scientists to undertake international cooperation. Researchers cooperate internationally when it is profitable for them in terms of academic prestige, scientific recognition and access to research funding, which is suggested by the three models proposed here (the model of credibility cycle in science, the model of prestige maximization and the model of global science). The total number of analyzed articles indexed in the Scopus database was 5.5 million, including 2.2 million articles written in international cooperation.
