In Lima, Peru, informal settlements exemplify this trend, revealing significant environmental impacts as progressive construction intensifies urban growth. Informal housing construction in Lima progresses through four key stages: Inception, Development, Completion, and Consolidation, each characterized by material additions and upgrades that increase embodied environmental impacts over time and across all life cycle phases. A Life Cycle Assessment (LCA) was applied to evaluate total greenhouse gas (GHG) emissions, water use, and fossil energy consumption across these four building consolidation stages. Additionally, three end-of-life scenarios—landfilling, recycling, and selective deconstruction were analyzed to assess the potential benefits of adopting a circular model in construction material use. The results show that the inception stage emits 1.6 Mt(CO2-eq), the development stage 23.15 Mt(CO2-eq), the completion stage 100 Mt(CO2-eq), and the consolidation stage 58 Mt(CO2-eq), totaling 183 Mt(CO2-eq). Due to lower average occupation density, informal housing emits approximately 450 % more GHG emissions per person than its formally constructed counterpart. The linear construction model exacerbates these impacts by generating substantial waste and requiring continual extraction of new materials. Selective deconstruction could reduce carbon emissions by 81 %, water use by 82 %, and fossil energy use by 80 % compared to landfilling. Recycling offers smaller reductions of 69 %, 68 %, and 67 %, respectively. These findings highlight the environmental benefits of integrating circular economy strategies and the need for sustainable material management policies in rapidly urbanizing areas.

These settlements are characterized by their socioeconomic disadvantage and being generally located in vulnerable areas along with disconnection from basic services. Urban regeneration projects in informal settlements have increased, however, the absence of a defined method for prioritizing the interventions to be performed has produced a mismatch between the implemented interventions and the local needs. Instead, these interventions tend to respond to preconceived agendas, which, in turn, leads to the creation of unsustainable projects. In this regard, this study proposes a three-phase methodology to prioritize interventions in terms of sustainable urban regeneration in informal settlements. In the first phase, a diagnostic matrix composed of 4 dimensions, 18 variables, and 61 indicators is built based on a literature review of sustainable urban regeneration. In the second phase, an interactive, publicly accessible web instrument is developed to visualize the indicator data for Metropolitan Lima. In the last phase, the instrument is tested, which results in a district-level diagnosis. The proposed methodological approach facilitates objective, rigorous quantitative analysis for local governments to optimize financial resource utilization and facilitate decision-making.

El objetivo fue identificar las características urbanísticas del campus, además de indagar por la relación entre el primer proyecto de la Universidad de Lima y los otros proyectos importantes de campus universitarios en Lima: la Ciudad Universitaria de San Marcos, de 1956, y el campus de la Pontificia Universidad Católica, de 1967. Se analizaron las características urbanísticas generales de cada referente y el caso de la Universidad de Lima.

Therefore, the constant promotion of a research culture within higher education institutions is an essential task for reducing the gap between scientific productivity and industry challenges and proposing solutions to real-life challenges. One of the main stages involved in any research process is the proposition of a methodological design: a detailed plan conceived and later developed to answer the research questions. Nevertheless, within the engineering context, even though a wide range of methodological designs are considered, these are not always explicitly stated in research papers, so at the undergraduate level there is an absence of more precise guidelines that allow a more concise orientation. Consequently, at this level, a challenge in research training is perceived. This provided a motivation: the development of a framework for the actors involved in research training at the engineering undergraduate level so that they can easily define the methodological design. In this context, the present research proposes a framework organized upon the two main phases of every research process: design and execution. The framework is expected to promote the proper use of research methodology among engineering students. Furthermore, the methodological design from 140 selected civil engineering papers from seven different knowledge fields is analyzed. Results show that 94.29% of the papers did not explicitly present the methodological design. It was concluded that there is an absence of it within the engineering field. Thus, a methodological design framework proposal for engineering students was developed to overcome this situation. © 2024 by the authors of this article.
