    Climate Change, Vulnerability, Social Conflicts and Human Displacement in the Andes: The case of Huaytapallana Glacier
    (2020-06-11)
    The objective of this review was to identify the links between Climate Change, Vulnerability, Social Conflicts and Human Displacement in the Andes. The different factors that influence the vulnerability of people and communities are analyzed, such as the diversity of the impacts of climate change, the retreat of glaciers, the loss of biological diversity, health, agricultural production and scenarios with the presence of water scarcity. Adaptive behaviors are observed in the inhabitants of Andean communities, but they are not sufficient, because in many occasions people are forced to migrate to other cities. Five ways of responding to climate risks or hazards are suggested: 1) reduction and control of global warming, 2) adaptation to conditions resulting from climate change, 3) resistance, 4) mitigation, and 5) involuntary displacement. Finally, it concludes by stating that there is an intricate link between global warming, climate change, vulnerability and social conflicts, and that migration is a product of climate change.

    Water resources management in vulnerable ecosystems: Quiroz river basin, Piura
    (European Center of Sustainable Development, 2020-01-01)
    According to the IPCC (2014), access to water resources is increasingly limited due to the effects of climate change; in consequence, vulnerability of ecosystems and their inhabitants increases. Thus, it is necessary to develop socio-organizational capacities to mitigate and adapt to this scenario, where retribution mechanisms for ecosystem services (MRSE for its Spanish acronym) become more relevant. The research attempts to analyze the coordination among agents involved in sustainable water resources management, to face climate change vulnerability in high biodiversity areas. For this purpose, the implementation of the Quiroz-Chira water fund will be studied as a case that generates institutionalism for sustainability of this mechanism and that represents an important social innovation that can be replicated. The methodology has a descriptive scope and applies qualitative techniques that complement secondary sources systematized with WebQDA software. Results indicate high vulnerability of the analyzed basin districts and a correct governance in this innovation, both with a sustainable development approach oriented to conservation of water potential. This implies good articulation for implementation of the MRSE and promotion of interests’ unification between contributors and water resources retributive entities.

    Reframing tropical savannization: linking changes in canopy structure to energy balance alterations that impact climate
    (Wiley, 2020-09-01)
    Abstract Tropical ecosystems are undergoing unprecedented rates of degradation from deforestation, fire, and drought disturbances. The collective effects of these disturbances threaten to shift large portions of tropical ecosystems such as Amazon forests into savanna‐like structure via tree loss, functional changes, and the emergence of fire (savannization). Changes from forest states to a more open savanna‐like structure can affect local microclimates, surface energy fluxes, and biosphere–atmosphere interactions. A predominant type of ecosystem state change is the loss of tree cover and structural complexity in disturbed forest. Although important advances have been made contrasting energy fluxes between historically distinct old‐growth forest and savanna systems, the emergence of secondary forests and savanna‐like ecosystems necessitates a reframing to consider gradients of tree structure that span forest to savanna‐like states at multiple scales. In this Innovative Viewpoint, we draw from the literature on forest–grassland continua to develop a framework to assess the consequences of tropical forest degradation on surface energy fluxes and canopy structure. We illustrate this framework for forest sites with contrasting canopy structure that ranges from simple, open, and savanna‐like to complex and closed, representative of tropical wet forest, within two climatically distinct regions in the Amazon. Using a recently developed rapid field assessment approach, we quantify differences in cover, leaf area vertical profiles, surface roughness, albedo, and energy balance partitioning between adjacent sites and compare canopy structure with adjacent old‐growth forest; more structurally simple forests displayed lower net radiation. To address forest–atmosphere feedback, we also consider the effects of canopy structure change on susceptibility to additional future disturbance. We illustrate a converse transition—recovery in structure following disturbance—measuring forest canopy structure 10 yr after the imposition of a 5‐yr drought in the ground‐breaking Seca Floresta experiment. Our approach strategically enables rapid characterization of surface properties relevant to vegetation models following degradation, and advances links between surface properties and canopy structure variables, increasingly available from remote sensing. Concluding, we hypothesize that understanding surface energy balance and microclimate change across degraded tropical forest states not only reveals critical atmospheric forcing, but also critical local‐scale feedbacks from forest sensitivity to additional climate‐linked disturbance.

    Environmental impacts of introducing cable cars in the Andean landscape: A case study for Kuelap, Peru
    (Elsevier, 2020-05-20)
    Cable cars have slowly become a popular means of transport beyond their classical use at ski resorts. In Latin America their use has thrived to access archaeological sites in the Andes, but also in urban environments for mass transit. Despite some apparent benefits of these systems, the current literature is scarce in terms of quantifying the environmental profile of cable cars. Hence, their environmental performance as compared to other means of transport remains essentially unexplored. Therefore, the main objective of this study was to provide a comparative environmental analysis, using Life Cycle Assessment (LCA) methodology, of the two existing transport methods to visit the Kuelap Archaeological Complex, in northern Peru: a recently built cableway system and the alternative unpaved winding road. An attributional LCA perspective was performed for several impact categories, including global warming and particulate matter formation. In addition, a scenario analysis and an uncertainty analysis, using Monte Carlo simulation, were conducted to account for deterministic and stochastic results interpretation. Results demonstrated that succulent environmental benefits are attained when cable cars substitute road transport in complex Andean orographic conditions. However, the rebound effects of reducing traveling times significantly, as well as social and biodiversity aspects, should be analyzed in further depth to complement the environmental analysis.

    “Climate change might have caused our small harvest”: indigenous vulnerability, livelihoods, and environmental changes in lowland and high jungle indigenous communities in Peru
    (Springer Science+Business Media, 2021-09-15)
    The purpose of this article is to analyze how indigenous livelihoods are challenged by the global phenomenon of climate change while paying particular attention to how historically shaped, non-climatic factors influence how climate change is experienced in the Peruvian Amazon. In this sense, we will address indigenous people’s lived experiences of climate variations using a theoretical framework based on concepts of vulnerability. Methodologically, we draw on both a recent literature review and fieldwork conducted during 2015 and 2016 with two Kukama Kukamiria communities in Loreto (low jungle) and three Ashaninka communities in Junín (high jungle). After describing our theoretical framework and qualitative methods, we discuss the economic history of the addressed areas and show how non-climatic factors, such as colonialism, influence these communities’ experiences. This context allows us to better understand indigenous people’s experience of seasonal variations, precipitations and climatic events, its effect on their livelihoods, and their adaptive strategies in response to challenges imposed by climate unpredictability and broader transformations in their territories. Our conclusions are twofold: (a) addressing climate change must incorporate multiple temporal and spatial scales and (b) non-climatic factors are integral to understanding the role of climate change vulnerability of indigenous population.

    Introducing environmental decision-making criteria to foster green public procurement in Peru
    (Wiley, 2021-07-01)
    Governments in the Global South have recently started to align their public procurement regulations considering Green Public Procurement (GPP) guidelines to achieve Sustainable Development Goal 12. In this context, it is important to establish environmental criteria to help decision making after analyzing the variety of options available in the market. Thus, using as examples two of the most acquired products in public procurement in Peru: Medium-density particleboard melamine furniture and paper offset, the aim of this paper is to determine the main environmental hotspots and therefore show the path to foster GPP in Peru. To achieve this goal, a Life Cycle Assessment was carried out considering it is a suitable environmental management tool to quantify environmental impacts. For this, a set of scenarios were modeled and compared for each of the two products selected, covering different geographical and technological options that are currently purchased by the Peruvian government. Results demonstrated that it is possible to attain considerable reductions in the environmental impact of the products analyzed if the main critical stages throughout their life cycle are identified and adequate solutions are applied to avoid burden shifting. Moreover, we argue that it is important for developing countries to carry out case-specific life-cycle inventories as they provide higher-quality information based on the particular characteristics of regional or local industries, allowing the determination of more realistic environmental impact mitigation benchmarks. Nevertheless, the inclusion of lifecycle-based criteria in GPP must be performed cautiously, avoiding command and control regulations, as numerous challenges remain in terms of capacity building, environmental awareness, and environmental information, and transparency in emerging and developing economies. Integr Environ Assess Manag 2022;18:1206–1220. © 2021 SETAC KEY POINTS Latin American governments are currently aligning their public procurement regulations with Green Public Procurement (GPP) guidelines to comply with international environmental recommendations, such as Sustainable Development Goals (SDGs) or nationally determined contributions (NDCs). Considering that these nations struggle to develop empirical data to support GPP initiatives, Life Cycle Assessment (LCA) is presented as an attractive environmental management tool to quantify environmental impacts and orient GPP regulations. Two of the most acquired public procurement products in Peru, melamine furniture and paper offset, were evaluated using LCA to identify environmental hotspots, the sensitivity of the results through scenario analysis, and improvement actions to mitigate greenhouse gas emissions and other environmental impacts. Despite the existing challenges linked to building environmental information in Peru, case-specific life-cycle inventories for regional industries have proved to allow the determination of realistic environmental impact mitigation benchmarks to include in GPP.

    Environmental footprint of critical agro-export products in the Peruvian hyper-arid coast: a case study for green asparagus and avocado
    (Elsevier, 2021-11-19)
    Peru has become one of the world's main agricultural hubs for a wide range of fruits and vegetables. Two of these products, avocado and green asparagus, have raised attention in recent years in the international scene from an environmental perspective due to the high amounts of water they require, as well as the long air and marine freighting distances to export these products to Europe, Asia or the US. Consequently, the aim of the current study was to perform an environmental assessment of these two products using two life-cycle methods: carbon and water footprint. For the latter, water scarcity, acidification, eco-toxicity and eutrophication impact categories have been selected for assessment. Inventory data were gathered from six different companies located in different regions of the hyper-arid Peruvian coast. The results report that the products are not carbon intensive and are in line with other similar plant-based products. Conversely, the hyper-arid conditions of the cultivation sites require a large volume of groundwater to fulfill the needs of the crops. Interestingly, even though this may lead to overexploitation of groundwater resources in the absence of appropriate management policies, the low mobility of pollutants, namely pesticides, constitutes a natural barrier to protect the degradation of natural water bodies. Similarly, highly technified irrigation systems have allowed minimizing the amounts of water used per hectare. In conclusion, results from this study may be useful in more concise environmental assessment studies on food products and diets, considering the consumption of these Peruvian products in many countries in the world. Furthermore, results are also important at regional level since they depict the carbon and water performance of these products and can also be accompanied by cross-cutting certification schemes, including Product Environmental Footprint Category Rules Guidance.

    District-level analysis for household-related energy consumption and greenhouse gas emissions: a case study in Lima, Peru
    (Elsevier, 2021-11-25)
    Given the significant contribution of households in terms of energy use and greenhouse gas (GHG) emissions, in addition to the increasing rate of urbanization and growth in developing countries, urban dwellings need to be analyzed in greater depth in order to implement sound policy-making based on informed decisions. Thus, the aim of this study is to quantify the household-related energy use and associated GHG emissions in the city of Lima, Peru, between 2007 and 2015. In order to understand the emission patterns within the city, a further analysis on smaller spatial scales (i.e., districts) has been performed using multiple regression analyses. Results show that household-related energy consumption and emissions, excluding those related to private vehicles, ranged from 2.92 to 3.22 GJ/cap/year and 187 to 249 kg CO2eq/cap/year, respectively. Overall, there is a transition in the use of energy and emissions, sustained by an increase in population and a change in the economic status of part of the population. Moreover, liquefied petroleum gas, rather than electricity, was found to be the main energy source in lower-income households. This study aims to help integrate household energy behavior with strategies for sustainable cities and provide a starting point to connect with climate policies.

    A method to include life cycle assessment results in choosing by advantage (CBA) multicriteria decision analysis: a case study for seismic retrofit in Peruvian primary schools
    (MDPI AG, 2021-08-01)
    Building information modeling (BIM) is an emerging technology that improves visualization, understanding, and transparency in construction projects. Its use in Latin America and the Caribbean (LA&C), while still scarce, is developing in combination with multi-criteria decision-making (MCDM) methods, such as the choosing by advantages (CBA) method. Despite the holistic nature of MCDM methods, the inclusion of life cycle environmental metrics is lagging in construction projects in LA&C. However, recent studies point toward the need to optimize the synergies between BIM and life cycle assessment (LCA), in which a method like CBA could allow improving the quality of the decisions. Therefore, the main objective of this study is to integrate LCA and CBA methods to identify the effect that the inclusion of environmental impacts can have on decision-making in public procurement, as well as comparing how this final decision differs from an exclusively LCA-oriented interpretation of the results. Once the LCA was performed, a set of additional criteria for the CBA method were fixed, including transparency, technical, and social indicators. Thereafter, a stakeholder participative workshop was held in order to gather experts to elucidate on the final decision. The methodology was applied to a relevant construction sector problem modelled with BIM in the city of Lima (Peru), which consisted of three different construction techniques needed to retrofit educational institutions. Results from the LCA-oriented assessment, which was supported by Monte Carlo simulation, revealed a situation in which the masonry-based technique showed significantly lower environmental impacts than the remaining two options. However, when a wider range of technical, social, and transparency criteria are added to the environmental indicators, this low-carbon technique only prevailed in those workshop tables in which environmental experts were present and under specific computational assumptions, whereas teams with a higher proportion of government members were inclined to foster alternatives that imply less bureaucratic barriers. Finally, the results constitute an important milestone when it comes to including environmental factors in public procurement in LA&C.
