Background: The article addresses, as a fundamental aspect, the numerical changes of the Camagüey population over 60 years of age. Objective: Analyze the aging dynamics in the province of Camagüey during the period 2015-2023. Methods: The spatio-temporal behavior of a set of indicators of the demographic dynamics of its population in the period was analyzed, which allowed the analysis of the impacts of demographic aging on dissimilar aspects of the sociodemographic reality of Camagüey. In a synthetic way, statistical, spatial statistics and geoprocessing methods are used to obtain, analyze, process and output information. Special emphasis is placed on using Geographic Information Systems which, in conjunction with other packages and tools, allowed the application of novel procedures such as spatial statistics techniques. Results: The execution of various spatial modeling actions it possible to obtain graphs and maps, which, through their analysis and interpretation, allow the establishment of possible lines of consideration when facing the process of population aging. Conclusions: The aging of the population of Camagüey constitutes a challenge for which actions must be prepared with a view to the comprehensive care of the elderly, in order to achieve the spatial sustainability of the process.

Inclusive education to face climate change in the university context
Background: The challenge posed by climate change requires active and inclusive participation, which presupposes the equal right and opportunities that every human being has to receive a quality education. Objective: To propose methodological details associated with inclusive education to confront climate change in the university context constitutes the purpose of this work, which constitutes an experience at the Céspedes Municipal University Center. Methods: A descriptive methodology was used, based on the qualitative approach. Theoretical and empirical methods were used, which allowed us to verify that there are still difficulties in recognizing inclusion as a process of increasing student participation to combat climate change. Results: The capacities and commitments that are generated from common and differentiated responsibilities to promote transformative action against climate change are aspects to which attention is paid. Conclusions: The application of Freire's conceptual and methodological principles to the proposed clarifications facilitated a change in the attitude of university students, as a life experience, in the inclusion-climate change relationship, with a comprehensive and participatory approach, showed greater involvement by putting students at the center of formal and non-formal education, as well as a high degree of satisfaction that contributes to commitment, motivation and cooperation, as agents of change, in achieving the sustainable development objectives of the Agenda 2030.

Background: Environmental education and communication are configured as instruments to promote adaptive governance with great potential to foster sustainability in higher education. Objective: To analyze the theoretical foundations that support the challenges and perspectives of environmental education, communication, and governance in Angolan higher education. Methods: At the theoretical level, the historical-logical, inductive-deductive, and analytical-synthetic methods were used; at the empirical level, documentary and bibliometric analysis was employed, supported by the PRISMA database management system. Results: The main challenges and perspectives of environmental education and communication in the formation of adaptive governance in higher education are presented, substantiated, and synthesized, with evidence demonstrating an effort to consolidate a more participatory, contextualized, and multidimensional university environmental sustainability that responds to current environmental challenges for the achievement of sustainable development. Conclusions: Environmental education and communication in higher education is a pairing that maintains a stable position within curricula, particularly in outreach programs. However, limitations exist in achieving progress that involves the university community in developing strategies aimed at promoting integrative methodologies focused on social responsibility and environmental governance within the university.

Impact on air quality of emission due to particulate matter emissions during ore transport
Background: Mining activity is an important source of air pollution where large amounts of particulate matter are produced that cause respiratory diseases and damage to ecosystems. Objective: To determine the impact on air quality resulting from the transport of ore on unpaved roads from the quarry front to the production centers in the UEB Mariel Quarries, Artemisa, Cuba. Methods: The emission of particulate matter resulting from the transport of ore on unpaved roads was determined using the methodology of the AP 42 standards of the Environmental Protection Agency of the USA. The estimation of particulate matter immission was performed using the simulator SCREEN3 which examines a full range of weather conditions, including all stability classes and wind speeds to find maximum impacts. Results: The result was an average maximum concentration of 821.59 μg/m3 when trucks are not transporting material and 1113.3 μg/m3 when carrying material for an average distance of 127.7 m. The values obtained are higher than the maximum admissible concentration stipulated in the Cuban standard on air quality NC 1020 2014. Conclusions: With the methodology of the AP 42 and the SCREEN3 simulator, a study of the air quality in the UEB Mariel Quarries was obtained as a result of the emission of particulate matter during transportation on unpaved roads. The results obtained are closely related to emission rates, which in turn depend on emission factors, road sizes and their corresponding areas.

Antimicrobial activity of the fluid extract of Cymbopogon citratus on Escherichia coli strains
Context: The Cymbopogon citratus plant has been studied with the aim of utilizing its compounds for the production of processed natural products intended to cure or treat various ailments or diseases. Objective: To explore, from a theoretical perspective, the antimicrobial activity of Cymbopogon citratus fluid extract against Escherichia coli strains. Methods: A literature review was conducted using sources included in the SciELO, Google Scholar, and Web of Science databases. The review focused on peer-reviewed publications in Spanish and English, published within the last five years and covering a related subject area. The final sample consisted of ten documents (two theses and eight articles) from an initial 156 after applying selection filters for accessibility, language, methodology, recency, and duplication. Results: The analysis revealed that Cymbopogon citratus essential oil, obtained primarily by steam distillation, exhibits significant antimicrobial activity against Escherichia coli, although with variability depending on the strain and extraction method. The studies, conducted in several countries, include experimental research, systematic reviews, and applications in food, highlighting both synergistic and antagonistic effects with antibiotics. Conclusions: Cymbopogon citratus products, especially in essential oil form, show significant antimicrobial activity against Escherichia coli. Although their interaction with antibiotics can be synergistic or antagonistic, depending on multiple factors, their integration into therapies requires clinical validation.

Population study of the Pseudophoenix sargentii in Francés Key, Villa Clara, Cuba
Abstract: Background: Pseudophoenix sargentii H. Wendl. is a species of native palm in Cuba that is located from Guantánamo to Villa Clara. In Cayo Francés it reaches its western limit and the largest natural population in Cuba is preserved. The excessive exploitation of use in gardening, using specimens extracted from natural habitats, one of the main causes of the decrease in their populations, requires the study presented. Objective: Determine the structure and population density of P. sargentii in Cayo Francés for conservation purposes. Methods: For the population study, the methodology of González-Oliva et al. (2017) was applied. Population size and structure were evaluated taking into account status classes and using transect sampling. Results: The population density of adults and juveniles was 512.5 individuals/ha, with the best balance found towards the eastern end of the key. The density of seedlings is also much higher towards that side, apparently due to the effect of strong winds that have created gaps in the forest that have favored the recruitment of seeds and seedlings. Conclusions: It is confirmed that P. sargentii is very well preserved in the coastal and subcoastal xeromorphic scrubland and in the microphyllous evergreen forest of Cayo Francés, with high density and an adequate population structure in the latter plant formation.

Historical trends of the spatial dimension in the geography teachers´ training
Abstract: Background: The article presents one of the partial results of the project “Pedagogical projection of the Life Task in the different educational levels” of the University of Camagüey “Ignacio Agramonte” in the period 2020-2025. A historical trend analysis is made of the treatment of the spatial dimension in the training of the geography teacher. Objective: To characterize the historical trends of the spatial dimension in the professional training process of the geography teacher. Methods: Methods such as analytical-synthetic, historical-logical and documentary analysis were used, with the purpose of developing a periodization that would characterize the historical trends of the spatial dimension in the professional training process of the geography teacher. Results: The study of the spatial dimension in the training process of the geography teacher, with emphasis on the incorporation, integration and work with geographic categories, allowed to determine historical trends of the process under study. Conclusions: The historical analysis reveals that the training of geography teachers has moved from a fragmentation caused by the division between biophysical and cultural elements, with a predominance of the ecosystemic and environmental, to the partial incorporation of the spatial dimension into the curriculum.

Environmental impact assessment of the establishment of silvopastoral systems in the municipality of Camagüey, Cuba
Background: The need to establish silvopastoral systems in the livestock agroecosystems of the Camagüey municipality, taking into account their impact on the environment. Objective: To evaluate the environmental impact that would result for the establishment of silvopastoral systems in livestock agroecosystems in the municipality in Camagüey, Cuba. Methods: Gómez Orea Methodology, to the assessment of impacts by the components of the subsystems: physical- chemical (natural), biological- ecological, economic- operational and environment. To interpret the result of the assessment of the impacts, the total values of incidence of each of them of the different components are added. Intervals of the values of importance were taken to give a classification of their degree of importance, significance: Very high: >120, High: 119-90, Medium: 89-50, Low: 49-10 and very low: <10. Results: Eighteen significant potential impacts were identified, of which 16 were positive and 2 were negative. Positive impacts accounted for 88,9 % of the total, while negative impacts assessed accounted for 11,1 %. Very high and high impacts accounted for two each, averaging 11,1 % of the total in each case, the medium impacts were four, averaging 22,2 % with low impacts accounting for 44,4 %. Conclusions: An impact indicator of 854 points is achieved, meaning that whit establishment of silvopastoral systems environmental resilience is increased, improving the physical, chemical and microbiological properties of the soil, biodiversity, animal well-being and the contribution to the mitigation of greenhouse effect.

Effect of crude extract of Tagetes erecta L. leaves on the control of four vegetable pathogenic fungi under in vitro conditions
The use of plants with biocidal properties is an important technological instrument within the ecological management of pests. In this work, the effect of the crude extract obtained from Tagetes erecta leaves at different doses on the in vitro control of Alternaria porri, A. solani, Cladosporium fulvum and Cercospora beticola, disease-causing agents in three horticultural crops, was evaluated. The method of obtaining the extracts was percolation with 70% ethanol, a solvent that was eliminated by rotoevaporation. The bioassay was set up according to a completely randomized design and the agar dilution method was used. The strains were isolated from field material. With the extract dose of 1g.L-1, inhibition percentages greater than 65% were obtained for all fungi. For A. solani, C. fulvum and C. beticola this dose was superior to Zineb (commercial fungicide used as a control). The data on pH, refractive index, color, odor, flavor and results of the phytochemical screening carried out on the plant extract are shown.

Melchor Ocampo: a naturalist patriot in the eyes of José Martí
The profile of Melchor Ocampo that appeared in the Universal Magazine on June 12, 1875 is commented on, whose distinctive stylistic features allow us to undeniably ensure that it was written by José Martí. The biography of this distinguished Mexican patriot is delved into and the motivations that could have induced the Cuban National Hero to make this praise are valued, among which stands out the bond that both felt for nature, the studies that the Michoacan had carried out about the plants, as well as the mutual interest in the vindication of American autochthony and the values of this continent.

Germination and short-term conservation of Melocactus guitartii León seeds (Cactaceae)
The germination of 50 seeds of Melocactus guitartii León (Cactaceae), six and twelve months old, collected in the town of Manaquitas, Cabaiguán Municipality, Sancti Spiritus in the month of July 2005, was comparatively evaluated. The evaluations were carried out during January and July. of 2006, respectively. Zeolite was used as a substrate in a cultivation house belonging to the Institute of Plant Biotechnology (IBP), in Villa Clara. The six-month-old seeds began to germinate on the thirteenth day, with 50% (or more) germination being recorded on the sixteenth day and germination of 42 of the 50 seeds evaluated (84%). While more than half of the one-year-old seeds They begin to germinate, at the same time, on the tenth day, a “little advance” compared to the previous group. Furthermore, 88% final germination was obtained on the fifteenth day. All this could indicate that, under the conditions evaluated, there is no decrease in the viability of the seeds but rather a slight increase in the final percentage, between seeds that are six and twelve months old. There is a decrease in dormancy, and germination is concentrated in a smaller number of days. Although such results could be influenced by differences in temperature, during the evaluation months, in the cultivation house.

More about the objectives of environmental education
The qualities of personality, whose development has been indicated as an objective of environmental education, are summarized and three not mentioned until now are added: feelings, behavior and performance. A systematization of them is offered, taking as criteria the position they occupy in the pedagogical process, depending on their character: cognitive (experiences, perception and knowledge), attitudinal (behavior, motivations, will, feelings, sensitivity, conscience, attitudes, behavior and values) or are related to training (habits, skills, abilities, competencies, participation and performance).
Ghost orchids in the protected areas of Camagüey
Information is offered about a very suggestive group of orchids that, due to their structural characteristics, growth and, especially the way they emit their flowers (which enigmatically seem to emerge from nowhere), have been baptized with the common name of ghost orchids, printing to landscapes an aura of beauty and mystery.

Aesthetic education for environmental training
A broad concept of aesthetics and the environment, as well as the development of aesthetic sensitivity seen as one of the objectives of environmental education, serve as the basis for a reconceptualization of aesthetic education. The sociocultural approach and the role of the other, defended by L.S. Vygotsky, as well as the unity between the affective - cognitive and theory - practice, are specified as the psycho-pedagogical foundations that support the development of aesthetic education for environmental training, in the context of developmental teaching.

The paper of the Padre Pío Galtés about the plant fossils of El Chorrillo; new reading 136 years later
Context: 136 years ago a scientific event of special relevance to science and technology occurred in Camagüey and Cuba. Objective: To present an annotated reproduction of the pamphlet Memoir on some plant fossils found in El Chorrillo (Puerto Príncipe), published in 1887 by Padre Pío Galtés, Escolapio. Methods: We worked basically with documentary review and consultation with specialized personnel. The information located on the 1887 editions was compared. Basic information was collected about the author, the institutions in which he worked in Cuba, as well as the people, botanical species and localities that are mentioned in the text, with details referring to the current toponymy. Results: During the first stay of Padre Pío Galtés in Cuba (1870-1887), he directed the boarding school of the Pías schools of Guanabacoa (1873-1885) and was rector of the one in Port-au-Prince (1885-1987). In this last year he made an expedition to El Chorrillo, there he collected plant fossils that he studied in detail and published a 19-page memoir, published in the city itself by the El Fanal Press, which is made available to contemporary readers. Conclusions: Monteverdia pays tribute to Padre Pío Galtés, a pioneer of science, who carried out his work under very difficult conditions, but with an important legacy, which must be studied by current and future generations.
