The topic addressed refers to one of the solutions applied to solve the shortage of fresh water caused by global warming. In the first part of the study, the notion of lacustrine ecosystem is defined and the consequences arising from the interrelationships between abiotic and biotic factors within the ecosystem. Particular attention was paid to the comprehension of newal index for reservoirs, based on which three categories of reservoirs were identified: oligodynamic, mesodynamic and polydynamic. The clogging of reservoirs and the risks that this process can generate on the operation and durability of hydrotechnical constructions, and the components of the surrounding environment constituted the study object of the fourth chapter. Finally, based on some dominant control factors (resistance index, erosion rate, hydrochemical type, degree of mineralization), several areas with different possibilities for setting up reservoirs were identified: degree I and II favorable, acceptable, and restrictive.

The study assessed farmers’ adaptation strategies of climate variability and implication on arable crops yield in Ogoja agricultural zone. Data collection procedure adopted for this study was the used of structured questionnaire, interview and focal group discussion. Four hundred copies of questionnaires were administered and three hundred and eighty eight were retrieved. The result revealed that the following adaptation strategies indicated that changing crop types /improved varieties has 70.6 percent negative and 29.4 percent positive respondent, soil and water conservation with 76.3 percent negative and 37.4 percent positive, changing planting time 62.6 percent negative and 37.4 percent positive respondent, cropping mixture or mixed cropping 32.2 percent negative and 67.8 percent positive, supplementary irrigation 55.9 percent negative and 44.1 percent positive respondent, mulching 30.2 percent negative and 69.8 percent positive, planting distance 68.0 percent negative and 32.0 percent positive, regular weeding 69.3 percent negative and 30.7 percent positive, planting trees 30.9 percent negative and 69.1 percent positive respondent ,early planting season with 41.2 percent negative and 58.8 percent positive and late planting season recorded 61.9 percent negative and 38.1 percent positive respondent. Relevant recommendations were made which includes that government should provide access to credit facilities to farmers. Besides crops that have natural adjustment potentials to climate oscillation should be cultivated and promoted. Finally, sustainable indigenous crops species with high yield and low risk as well as environmental education should be adapted.

The present work aims to make a contribution to raising the level of awareness regarding the influence of environmental factors on the human community, by calculating two biometeorological indices, namely Universal Thermal Climate Index (UTCI) and Heat Stress Index (HSI), which provide quantitative assessments of the thermal stress experienced by human populations in the examined region. Therefore, using the Bioklima software, the two biometeorological indices were calculated based on meteorological parameters recorded at the Constanța and Tulcea meteorological stations during the period from 2016 to 2022. Consequently, the results obtained based on the analysis of the extreme values of the UTCI index, indicate “no thermal stress” as the category of thermal comfort with the highest frequency during the studied years, at both stations. At the same time, the maximum HSI values suggest that the thermal comfort category “slight and moderate heat stress” was the most prevalent during the analyzed period at the Constanța meteorological station, while at Tulcea the most frequent thermal comfort category was “slight cool stress”. It is noteworthy that, although these desirable thermal comfort categories were predominant, categories illustrating weather conditions that pose a threat to the health of organisms (particularly humans) were also recorded during the studied years.

The variability of air temperature was marked by periods of climate warming and cooling with random intensities and durations but they maintained the living existence and especially of the human species. They are determined by the variability of the cosmic factors that essentially determine the earth's climate. In this paper we analyzed the variation of the air temperature in Oltenia during the autumns for the interval 1961-2023. A series of our other works analyzed climate variability in this part of Romania. The warm interval 1945-1955 was followed by a gradual cooling of the climate, and in the interval 1968-2000 (for 38 years), there were only three warm autumns (c – 1984, 1987 and 1994) and only 5 warm autumns (warmish) (cl - slightly warmer than normal – 1969, 1976, 1981, 2000 and 2004). Then the frequency of warmer than normal months and autumns gradually increased with the year 2006, reaching a maximum in the interval 2009-2023 in which two very warm autumns were also recorded (fc – 2019 and 2023). Several daily temperature climate records were broken but seasonal ones were not. At the same time, in the analyzed interval, the pace of ice melting intensified in the polar areas and exceptional thermal maxima were recorded in the cold season. Early autumn frosts also occurred in warm autumns and did significant damage to unprotected vegetable crops. Random variability of air temperature determined by random variability of cosmic factors is the main cause of these thermal variations. The paper is useful to all those interested in climate variability in Oltenia.

In recent years, one of the significant challenges for Szeklerland has been the migration of young people and the need for the renewal of local communities. Development is essential to ensure that the region remains attractive and competitive in tourism, economy, and culture alike. The involvement and active participation of young people in municipal life and decision-making not only contribute to strengthening the local brand but also increase the likelihood of young people staying in the area. The Municipality of Târgu Secuiesc supports youth initiatives to create a youthfriendly brand. Place branding is not just a communication strategy but a series of concrete actions reflecting the city's true identity and strengths. The active involvement and satisfaction of the local community and residents are crucial for the success of urban marketing. This study examines the role of young people in shaping place marketing.

Nowadays, development has become a natural part of our lives, the dynamics and types of which are the only things we tend to highlight and compare. This is why it may seem unusual that science has identified an anomaly in certain territorial units where there is a lack of development. This situation has been called the development trap. The development of an area is, of course, dependent on a great many factors, so that the range of development traps seems almost inexhaustible. This paper takes stock of the development traps identified so far, not with the aim of questioning the methods used, but to evaluate the data and indicators used to identify them. The study concludes that macro-level data are not causes but consequences, masking the true root causes of problems, but they play an important role in establishing a diagnosis at the regional level. The study aims to provide a convincing illustration, using concrete examples, of the development policy approach - and its main features - that can help to overcome the various pitfalls.

The paper focus on the period of COVID-pandemic and post-pandemic years in a medium sized city’s local housing market. Our research framework was to identify the direct effects even the pandemic and later the energy crisis, arose as a consequence of Russian aggression against Ukraine. On the other hand, we try to follow the changes of housing market trends not just in the city alone, but in the surroundings, too, concentrating on suburbanisation, as an emerging phenomena after the transition (post-1990 period) in a post-socialist context. The case study area was Pécs, one of the regional centres in Hungary, with a university town character, and less successful pole of FDI led re-industrialisation. Our major results suggest, that global challenges affect local markets directly. In a wider term, we find the 2020s as a turning point, after a long regeneration period in housing market after the global fiscal crisis (2008-2013 in Hungary). The COVID-pandemic closed the era of conjuncture and the next few years did not show a clear characteristic, but short-term micro-cycles followed each other, influenced by the elements of the governmental support system. To point out the recent changes, we used a quantitative methodology, based on different data sources (CSO, self-built) and find some correlation between some basic indicators. Suburbanisation, as a ‘western’ type phenomena could be register around Pécs, but the de-concentration of well-off groups prefer only a few settlements close to the city, and neglect a higher number of smaller villages with worse accessibility, lower level of local services, less diverse local economies and less perspective wages. Connecting with our theories we used, the production of space, and agency theories has the more direct causality with our results. The professional developers, the local governments and the most powerful actor, the central government fuel the changes in the local (urban area level) housing market trends, through forming the space following the needs of middle- and high-income groups. The spatial transformation of the suburban area around Pécs deeply rooted in the post-socialist (neo-liberal) way of development in the majority of East-Central-European space. This study is part of a larger long-term project financed by the NRDI Fund of Hungary („The effect of housing market processes on spatial (social) structure of Hungarian regional centres” – K131534) concentrate on five larger cities, including Pécs, and their suburb.
