Circular Economy in the Global South
The Global South faces unique sustainability challenges especially around the use and management of resources, providing a timely opportunity to understand and adapt Circular Economy (CE) approaches and initiatives, to chart a research agenda for these regions. During the 12th International Conference on Industrial Ecology (IE), ISIE Singapore 2025, we hosted the first special session to unpack the variety of research and key issues related to CE…
The use of remote sensing to detect illegal, unreported, and unregulated (IUU) tuna fishing activities in the Peruvian Exclusive Economic Zone
Illegal, unreported, and unregulated (IUU) fishing activities have historically been difficult to detect due to a lack of adequate monitoring and surveillance technologies. In recent years, advances in computational capacity and the growing availability of fleet tracking datasets have enabled the development of algorithm-based tools for monitoring fishing activity. Additionally, satellite geolocation systems, such as Automatic Identification Syst…
Knowledge gaps and future research priorities linked to microplastic abundance and occurrence in Peruvian fisheries and seafood products
Integrating technology and environmental data to predict mismanaged plastic waste in a watershed
Comprehensive methods for estimating mismanaged waste accumulation in the environment are limited, especially in the Global South, and new technologies are urgently needed. Here, we applied the Azure system, a physical floating barrier designed to retain and extract river floating waste while providing observational data of mismanaged waste, comparing results with a modeling tool that uses material flow analysis to provide estimates of mismanaged…
Analyzing the behavior of beachgoers in the city of Lima and their relationship with potential plastic emissions
Beach littering is a source of marine plastic waste accumulation. This is particularly so in overcrowded beaches in the Global South in which cleaning measures are scarce or sporadic and lack of waste management systems can increase plastic release. In the current study we focus on the importance of the behavior shown by beachgoers and how their conduct relates to the amount of plastic that potentially ends up entering littoral ecosystems. Transp…
Are Peruvians moving toward healthier diets with lower environmental burden? Household consumption trends for the period 2008–2021
Peru is one of the most diverse countries in the world in terms of food production, but also suffers a wide range of food security challenges, including malnutrition, the impact of natural hazards, and rising food prices. People living in poverty conditions are the main victims of these problems, which trigger undernutrition, obesity, and diet‐related non‐transmittable diseases. Despite these challenges, Peru lacks historical food intake data. Th…
Understanding the evolution of cities through urban stocks
The evolution of cities follows distinct patterns that connect to the cultural and socioeconomic aspects of their populations and can be understood by studying their urban stocks. This paper examines the evolution of construction materials stocks (MS) in the building sector in five urban areas in Peru. The study employed a bottom‐up methodology and focused on the city of Abancay in the Peruvian Andes, comparing it to the coastal cities of Chiclay…
Carbon and water conservation value of independent, place‐based repair in Lima, Peru
To what extent do repair and maintenance of consumer electronics conserve the materials and energy they embody? In this paper we examine the conservation value of a cluster of independent third‐party electronics repair businesses in Lima, Peru. Drawing on a combination of methods that include fieldwork, digital methods for online sociology, and life cycle assessment (LCA) of phones and tablets we quantify the conservation value of typical repairs…
District-level analysis for household-related energy consumption and greenhouse gas emissions
Evolution of the stock of electrical and electronic equipment in the Peruvian residential sector
Consumption of appliances in the residential sector in Peru has been growing continuously during the last 20 years. Although social benefits due to this growth are evident, there are also some related environmental impacts in the use and end‐of‐life (EoL) phases (e.g., inadequate handling or disposal at the EoL stage). Nevertheless, there is also a hidden potential in the growing stock of household appliances, such as their potential exploitation…
Developing a methodology to quantify mismanaged plastic waste entering the ocean in coastal countries
Marine plastic accumulation has gained international attention in recent years. Sources, pathways, and environmental impacts are being currently studied to understand the complex interactions during waste, especially plastic, transportation to the sea. Rivers have been identified as debris corridors allowing transportation of mismanaged waste. However, there is also evidence of waste accumulation in river basins, suggesting they can also act as s…
An interdisciplinary approach to identify zones vulnerable to earthquakes
Geospatial Characterization of Material Stock in the Residential Sector of a Latin‐American City
Building stock constitutes a huge repository of construction materials in a city and a potential source for replacing primary resources in the future. This article describes the application of a methodological approach for analyzing the material stock (MS) in buildings and its spatial distribution at a city‐wide scale. A young Latin‐American city, the city of Chiclayo in Peru, was analyzed by combining geographical information systems (GIS) data,…
Applying the Technology Choice Model in Consequential Life Cycle Assessment
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…
