Impacto de la estación Gamarra del Metro de Lima en el valor del precio del suelo en áreas comerciales

José Luis Matos Huamán — 2024-11-29

Este trabajo tiene por objetivo determinar el impacto de la proximidad de la estación Gamarra de la Línea 1 del Metro de Lima sobre el valor del precio del suelo. Para lograr este objetivo, se empleó el método de precios hedónicos, se observaron 83 predios alrededor de los 400 metros de la estación Gamarra, 50 de los cuales eran predios que están dentro del área de influencia. Los resultados indican que la proximidad de la estación Gamarra incide en el valor del precio del suelo en -5.4%, para aquellos predios dentro del área de influencia, y para los que están fuera de ella, la proximidad de la estación Gamarra incide en -31%. En ese sentido, la proximidad de la estación Gamarra incide de forma negativa en el valor del precio del suelo en su área de influencia, que es un área urbana comercial importante en la ciudad de Lima metropolitana: El emporio comercial Gamarra. La hipótesis fue comprobada pero aún es preciso estudiar el impacto de una estación en áreas residenciales.

Modelamiento basado en agente de la dinámica del comerciante ambulante y su influencia sobre la habitabilidad urbana

Mibeldy Addais Marcelo Niño — 2024-11-29

This study analyses the dynamics of street vendors in urban public space through agent-based modelling, assessing their self-organisation and its impact on urban habitability. Using two models, the self-organisation of street vendors is simulated in a virtual environment, each cell representing random values of profit and habitability. Model A, a search algorithm, considers the need for sale and the level of urban habitability, while Model B also incorporates social capital, represented by mutual aid networks between customers, suppliers and vendors. The results show that Model A achieved an average urban habitability of 2.85 and profits of 2.50, compared to Model B, which presented a habitability of 1.19 and profits of 2.60. The correlation between urban habitability factors was high in both cases (R=0.998 and R=1). The analysis reveals that the Street equalizer factor, with values of 58.18 in Model A and 57.88 in Model B, is the most relevant weighted component in the habitability formula. These findings highlight the self-organization of street vendors as a viable strategy for their establishment in regulated areas of urban space.

Urban renaturalization strategies for social integration and prevention of informal expansion in Laderas de Villa María del Triunfo, Lima, Peru

Nicol Selene Baldeón Trigozo — 2024-11-24

Exponential population growth on the hillsides of Lima, driven by informal urban expansion and lack of government regulation, has generated precarious and vulnerable settlements, exacerbating socio-spatial segregation. The use of the qualitative methodology used in the case, with field visits and interviews, supports the renaturalization proposal to address the problems that were recorded. Renaturalization seeks not only to restore environmental balance, but also to improve living conditions and reduce social and climatic vulnerability. The results obtained suggest the need for active community participation in the renaturalization process, considering environmental and social aspects. Security and regulation strategies to prevent informal occupations in renovated areas are considered in a Master Plan proposal, based on the results obtained. This comprehensive approach seeks to improve the current quality of life and promote long-term sustainable and equitable urban development.

Resiliencia indígena: El impacto de proyectos o megaproyectos de la apropiación de uso de suelo en la comunidad indígena Awajún en Amazonas, Perú

Gianella Katherine Ramos Samán — 2024-11-24

This paper analyzes 3 megaprojects on dams, mining and oil activities located in the district of Condorcanqui, and shows how these projects or megaprojects impact the Awajún indigenous community in the Peruvian Amazon. It also analyzes the impact of these economic and political initiatives on the traditional practices and spatial organization of the community. Despite bringing economic and infrastructural opportunities, they also generate conflicts and displacements, threatening the social and cultural cohesion of this indigenous people. Despite these challenges, the Awajún community has demonstrated remarkable resilience through the revaluation of their traditional knowledge and territorial self-management strategies, such as the legal defense of their lands and the adaptation of agricultural and construction practices. The study highlights the need for development approaches that respect indigenous rights and integrate communities in the planning and implementation of projects for genuine sustainability, recognizing their crucial role in the management and protection of natural resources and ensuring comprehensive sustainability.

Conservation development plan for historic centers with disaster risk management strategies case study: Historic center of Ayacucho

Marjhory Nayelhi Castro Rivera — 2024-11-24

Historic centers and heritage areas in Peru are always in a state of constant vulnerability, with many improvement plans in place. However, these plans often overlook the climatic environment, which is one of the main factors worsening the physical condition of monuments. For instance, heavy rainfall poses a continual threat in the highlands of the country, where attempts have been made to apply waterproofing interventions to urban structures, such as in the historic center of Ayacucho. Therefore, this article aims to assess the impact of the stormwater drainage project on the conservation and rehabilitation of Ayacucho’s historic center through open surveys and the enhancement of economic value by managing disaster risk in Ayacucho.
