The main objective is to analyze the environmental impacts of a set of 47 Peruvian food diet profiles, including geographical and socioeconomic scenarios. In order to do this, Life Cycle Assessment was used as the methodological framework to obtain the overall impacts of the components in the dietary patterns observed and primary data linked to the composition of diets were collected from the Peruvian National Institute for Statistics (INEI). Results were computed using the IPCC 2013 assessment method to estimate GHG emissions. No significant differences were observed between cities located in the three Peruvian natural regions.

Urban environments in Latin America must begin decarbonizing their activities to avoid increasing greenhouse gases (GHGs) emissions rates due to their reliance on fossil fuel-based energy to support economic growth. In this context, cities in Latin America have high potential to convert sunlight into energy. Hence, the main objective of this study was to determine the potential of electricity self-sufficiency production and mitigation of GHG emissions in three medium-sized cities in Peru through the revalorization of underutilized rooftop areas in urban environments.

Demand for grapes to produce pisco in southern-coastal Peru is expected to double by 2030. However, the appellation of this beverage confines the production and limits the space for agricultural expansion, leading to a situation in which potential competition for resources with established constraints is foreseen. Hence, the objective of this study is to understand the environmental impacts, focused on climate change and water consumption, linked to the agricultural dynamism in the valleys of Ica and Pisco due to an increase in the demand of pisco. For this, the viticulture system was analyzed regarding predicted changes in terms of expansion, displacement or intensification using a consequential life cycle assessment (CLCA) approach, identifying the environmental consequences of these shifts. A two-step CLCA model was used based on the results of a previous attributional study, in which...

Motivation and problem definition: A large number of public buildings designed with obsolete criteria are at high seismic risk and in need of structural rehabilitation. The task of selecting the optimal strategy poses important challenges for decision-makers due to the variety of intervention options and the fact that the construction sector is perceived to be one of the most corrupt in the economy. Objective: Given that transparency is an efficient anti-corruption strategy, a protocol is proposed for decision-making in seismic rehabilitation projects of public infrastructure that incorporates criteria which serve to increase transparency in the project development. Methods: Firstly, the literature was reviewed to describe current practices and regulations linked to decision-making in seismic rehabilitation/retrofitting of buildings. Secondly, relevant criteria that should be taken into ...

Waste management in cities has proved to be a complex task for policy-makers who seek cost reductions when taking decisions. However, on many occasions substantial environmental gain can be attained through waste management optimization. In this particular study, the main objective was to combine operational research techniques with Life Cycle Assessment to locate collection sites for general and recyclable residues and create an effective collection-route system for compactor trucks to attain a reduction in environmental impacts. The case study selected was the district of Comas, one of the most populated districts in the city of Lima, a city that has experienced several episodes of poor waste collection management in recent years. For the location of the collection sites a mathematical optimization model was proposed to decide where to locate them, as well as the number of containers r...
