Epistemes otras y cambio social: sentidos de lo interdisciplinario
(Pontificia Universidad Católica del Perú, 2024-05-30) Rueda Barrera, Eduardo A.
The paper addresses the significant role that other forms of knowledge must play in the construction of alternatives to overcome the most pressing problems faced by today's global societies, namely: local and global environmental degradation, social inequality and inequity, and violent conflict at various scales. To do so, it characterizes and provides reasons to validate other forms of knowledge, particularly those anchored in the social experience of indigenous peoples, women, and laypeople, and advocates for an understanding of interdisciplinarity as an ethical-political agency obligated to open, for transformative purposes, paths of dialogue between such forms of knowledge and academic disciplines. The purpose of this dialogue is not other that catalyzing, through the effects of such forms of knowledge, the production of genuinely innovative visions and practices in the face of the challenges that confront us today.

El desarrollo de la conciencia ambiental en la didáctica del sistema educativo
(Pontificia Universidad Católica del Perú, 2024-05-14) Rodriguez La Rosa, Sara Nataly
This study aims to present the different theories on the development of environmental consciousness that, throughout history, have influenced educational system didactics and human behavior, in order to achieve a sustainable pro-ecological attitude change. To do this, the PRISMA methodology was used and 10 articles were prioritized, respecting eligibility criteria and filters. The inquiry was conducted considering variables according to data from Web of Science and Scopus for the period 2020-2023. The results suggest that the various theories on the development of environmental consciousness embraced by the Peruvian educational system have significantly impacted didactics focused on the holistic formation of the individual in favor of the environment; an aspect that gives us hope for creating a world where there is a balance between humans and the environment, with emphasis on sustainability and respect for all elements and living beings, where ecological morality and ethics prevail over any profit-seeking endeavors.

El ecofeminismo: la inclusión de la ética del cuidado a la reflexión sobre la crisis ambiental
(Pontificia Universidad Católica del Perú, 2024-04-26) Castro-Bernardini, Ximena
In this research, a review is made of the contribution of constructivist ecofeminism to the analysis of the environmental crisis. This ecofeminism proposes including gender categories and approaches of theoretical feminism in the analysis of the current environmental situation. Figures from the last year on the sexual division of labor - domestic and paid - in Latin America have been reviewed with the aim of identifying and highlighting the inequality of the sexual division of labor while recognizing that care work is still awarded in its majority to women. This article will show that the universalization of care experiences that are taken up from the ecofeminism of Alicia Puleo and in the Ethics of Care can be of vital importance as a measure of transformation of the relationship between human beings and nature.

Evolución espacio-temporal de las unidades de ordenamiento ambiental (ZPB, ZPAES) y el refugio de vida silvestre de Los Pantanos de Villa, Perú (1987-2022)
(Pontificia Universidad Católica del Perú, 2024-05-09) Fabian Tolentino, Elveis Daniel; Torres Cordero, Nina Aleli; Bardales Martínez, María Fernanda; Naquiche Yesquen, Dagnert Luis; Ramírez Huaroto, Dámaso Wilfredo
Coastal wetlands adjacent to urban areas, such as the Pantanos de Villa in the city of Lima, Peru, are subject to constant changes in land use due to anthropogenic interaction. This has led to the reduction of dense vegetation areas, giving way to built-up areas. Therefore, this article addresses the issue of the physical changes experienced in urban areas adjacent to the wetland, such as the environmental management units, in this case the Zone of Protection of Outcrop and Surface Runoff (ZPAES), and the Zone of Landscape Protection of Edge (ZPB), as well as the Pantanos de Villa Wildlife Refuge (RVSPV), as a result of rapid urban expansion. Therefore, the objective of this research is to analyze the spatial and temporal evolution of the Pantanos de Villa environment and urbanization within the Environmental Management Units ZPB, ZPAES, and RVSPV. To achieve this, the Google Earth Engine (GEE) platform was used, and satellite images from Landsat 5 TM and Sentinel 2 MSI sensors were processed. These images were worked on in the GEE interface and analyzed using spectral indices, NDVI and NDBI, through map algebra codes and pixel masking. For cartographic representation, a Geographic Information System (GIS) was used. The results show a 291.12% increase in built-up area and a 26% reduction in vegetated area over the last 35 years, for the Environmental Management Units ZPB and ZPAES, and the RVSPV. The identified reduction is directly related to unplanned expansion of urban areas and anthropogenic activities.

Ecoficciones y procesos artísticos: la producción de obras artísticas y la relación simbólica con el territorio habitado y construido
(Pontificia Universidad Católica del Perú, 2024-05-06) Villavicencio Monti, Karla Paola; Hernández Calvo, Max Alfredo; Escribens Bacigalupo, Alessandra
This article intends to explain the different possibilities of representation of what we will call “fictional ecosystems”, being imaginary ecosystems that are developed through visual representation, highlighting their importance to establish, develop and maintain a connection with the inhabited territory, as fundamental relationship to build a society that questions the subjectivities established in the coexistence with the natural, humanized and collective environment. Thus, an explanatory line is developed, which answers the following question, can elements of visual representation be used for the creation of “fictional ecosystems” that help to question the relationship that we build with our natural and humanized ecosystems in the contemporary environment and its corresponding problems? The answer is built through a methodology created using two phases of analysis. An explanatory line is drawn through artistic proposals made in Peru, developed on different supports and using various means, such as painting, drawing, installation and video art. The first phase called “Ritualized Territory and Creation” deals with the relationship between own experiences in the territory of the artists and their creative processes; the second phase “Territory and Cultural Imaginaries”, highlights the intrinsic link between the experiences established in the previous phase and the construction of imaginaries that enable to question our cultural and ethical environment. It is attempted to highlight the importance and the fundamental role of the abovementioned representations as a bridge for a better understanding of the framework of subjectivities that triggers the relationship between natural and humanized ecosystems. This methodology will be explained through the development of four projects: “Abglutia”. “Peligro de Extinción”, “Natural Sense Making” and finally, “Pestes”. Through the analysis of these projects, it is recognized that the visual representations of these fictional ecosystems are useful and necessary to develop a critical view that promotes introspection and questioning about the relationship with our natural environment and the ecosystems that have influence on it, enabling to establish in our collective relationships the development of a symbolic relationship with the territory that we inhabit and build.

Hidrógeno verde: abriendo las puertas a un futuro energético sostenible en el Perú
(Pontificia Universidad Católica del Perú, 2024-05-06) Aranibar Ramos, Edgar Romario; Olarten Pacco, Miguel Angel Demetrio
The concern for climate change has driven the search for sustainable energy solutions. In this context, green hydrogen stands out as an emerging and promising option, given its carbon-free production and extensive applicability. However, its academic approach at the Peruvian level is still limited. Therefore, the objective is to analyze the potential of green hydrogen in Peru, considering technical, economic, environmental, and regulatory aspects. The study is based on a review of Peru's current energy matrix, identifying its challenges and limitations, and explores the opportunities and advantages that it could offer in the national context, also examining international experiences. It is observed that Peru has a diverse energy matrix but faces challenges in terms of infrastructure, dependence on fossil fuels, and vulnerability to international price fluctuations. Green hydrogen has the potential to harness renewable natural resources and offers economic, environmental, and social benefits, as well as greater energy diversification and security. It is concluded that the successful implementation of green hydrogen in Peru will require addressing technical obstacles, establishing a solid regulatory framework, and ensuring access to affordable financing. International experiences highlight the collaboration between the government, industry, and academic institutions to accelerate the development of these technologies. Additionally, the establishment of regulatory and political frameworks that provide security and promote collaboration is necessary. One limitation of the work is that it briefly addresses the cost aspect of production plants, a potential point for future research.

¿Ideales cosmopolitas? Del reino de la libertad a la asunción de la necesidad. Los desafíos de una lectura feminista de cara al sur
(Pontificia Universidad Católica del Perú, 2024-04-26) Ciriza, Alejandra
Under the conjecture that embodied people draw expectations of emancipation on the basis of a certain historical horizon, this work investigates the limits and pressures that the current conditions of existence imprint on the political imagination of those who inhabit the south of the planet, at a time of increase in inequalities between human beings and aggression against the nature that we are and in which we live. This work traces, from a situated and feminist perspective, some significant temporal milestones because these marks in time account made possible a cosmopolitan horizon, in which we can take notice that the world with which we stay, in which we live, is one. Under the sign of the French Revolution, Kant constructed the idea of a cosmopolitan government and imagined a norm for regulating relations between states that would enable a hospitality capable of welcoming the stranger as a full subject of law. Under the imprint of 1848 (and also of 1871) Marx projected, from the terrain of history and class struggle, the possibility of an emancipation that could be international. The world today shows a desolate panorama: the globalization of the world with its aftermath of reification and commodification of nature, with the bet on war in its different versions as a way out of the capitalist crisis, with fierce competition for what has become scarce: fuel, land, water, seeds. Cosmopolitanism, as an ethical and political imperative, invites us to take on the challenge implied by the impossibility of reproducing life on the planet under the current conditions of capitalist globalization. The cosmopolitan horizon can no longer be the realm of abstract freedom, but that of the assumption of the determinations of the realm of necessity: dependence on the nature that we are and in which we live, the importance of the body, the need for food, affection, care that human been can only satisfy in community.

Efectos de Bacillus spp. en organismos no diana del ecosistema terrestre
(Pontificia Universidad Católica del Perú, 2024-04-26) Castañedo Hernández, Zoe Alicia; Meneses-Marcel, Alfredo; Marrero Chang, Osmany; Cruz-Martin, Mileidy
The increase in the world population brings with it the need for food production and therefore the search for technological alternatives to satisfy this demand. According to the Food and Agriculture Organization of the United Nations (FAO), it is necessary to evaluate both the effectiveness and the safety of all products used in agriculture. The Institute of Plant Biotechnology of the province of Villa Clara, Cuba, immersed in the solution of this problem, has shown that two biopreparations CCIBP-C5 (Bacillus pumilus) and CCIBP-A5 (Bacillus amyloliquefaciens) have an effect on plant growth and activity against phytopathogenic fungi. However, there is no evidence of its safety on non-target organisms in the ecosystem. Terrestrial ecotoxicology is the branch of science devoted to predicting said impact on representative organisms. Four tests were carried out to evaluate the acute toxicity of Bacillus species at concentrations of 108 UFC.g-1 of soil, according to the regulations of the United States Environmental Protection Agency (EPA) in the biomodels of Eisenia fetida and different species of terrestrial plants. Mortality/germination inhibition, weight, vegetative vigor and other clinical findings were investigated for 30 days. There was no mortality in any of the biomodels and the observed effects did not show significant statistical differences with the corresponding control group. We can conclude that the CCIBP-C5 and CCIBP-A5 biopreparations are not toxic to the species studied in the terrestrial ecosystem.
