The study of the population is of vital importance for the planning of a country, these are sources of information for administrative decision-making. In Cuba, there are national and provincial regularities regarding the main demographic variables, but particularities are appreciated in the municipalities; above all, in those with mountainous characteristics, as is the case of Manicaragua, in the Villa Clara province, in Cuba. The objective of the work is to describe the demographic variables of the Manicaragua municipality, Villa Clara between the years 2016 and 2019. Methods of the theoretical and empirical level were used, the review of documents being fundamental, focused on the analysis of statistical, national, provincial, and municipal from 2016 to 2019. The data obtained corroborate a negative annual growth rate in the years analyzed, ranging between (-9.5) in 2016, to (-10.9) in...

The risks of environmental pollution occupy a relevant place in the scheme of ecological studies at the national and territorial level. These must be treated with the articulation of a system of preventive measures and proactive solutions that contribute to mitigate the consequences of the negative deterioration on the existing ecosystems. The objective of this research was to evaluate the environmental impact of the solid particles dispersed in the air resulting from the fires that occurred in the Municipal Landfill of the city of Santa Clara, in Villa Clara, Cuba, on the community of Caracatey, due to its proximity to the landfill and the spatial reach that these particles had in the city of Santa Clara.

Biology, geography, and Chemistry, achieve greater environmental awareness. For the development of the research, information collection methods (participatory observation, document review, survey, interview, expert criteria) and collected information processing methods (analysis - synthesis, induct...

The research carried out consisted of the design, elaboration and proposal of a system of workshops with the objective of contributing to the knowledge about Invasive Exotic Species (IES) of plants, by school children of the Rural Basic Secondary School "Wilmina Vizcaino Sarduy" located in the town of Manajanabo, in the municipality of Santa Clara, province of Villa Clara, in the Republic of Cuba. For the development of the research, different methods of information gathering and processing were used in their dialectic interrelation, which allowed verification of the existing deficiencies regarding the knowledge of plant species considered to be IES and their undesirable effects on the vulnerable Cuban ecosystems, considering that there are 8 species of invasive exotic plants in the area. The system of workshops was proposed from the school's educational project. The proposal was evaluat...
