Item type:Publication, 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. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The perception of the impacts of climate change in communities surrounding Lake Titicaca, Peru-Bolivia.(Faculty of 1000, 2026-05-26)<ns3:p> Background Climate change is increasingly transforming socio-ecological systems in high-Andean regions, particularly in communities surrounding Lake Titicaca, where livelihoods depend heavily on climate-sensitive activities such as agriculture, fisheries, livestock, and tourism. Despite growing environmental pressures, limited evidence exists regarding how local populations and institutional actors perceive climate-related impacts and adaptive responses in this transboundary region. This study analyzes climate change perceptions, perceived impacts, and adaptation capacities in communities located in Puno Bay (Peru) and Cohana Bay (Bolivia). Methods A mixed-methods approach integrating quantitative and qualitative techniques was applied during fieldwork conducted in November 2024 and June 2025 in the communities of Quehuaya, Capachica, Guaqui, and Puno. Data collection included structured surveys administered to 62 community members and 26 institutional actors, semi-structured interviews, participatory workshops, and participatory mapping exercises. Descriptive statistics, chi-square tests, and Spearman correlations were used for exploratory quantitative analysis, while qualitative information was analyzed through thematic coding and socio-ecological interpretation. Results Findings revealed high levels of climate change awareness among community members (85.5%) and institutional actors (100%). Respondents identified reduced rainfall, increasing temperatures, hydrological variability, declining agricultural productivity, reduced fish availability, and tourism-related impacts as the principal perceived effects. Significant differences were identified regarding adaptation measures (χ <ns3:sup>2</ns3:sup> = 14.96, p < 0.001) and institutional support (χ <ns3:sup>2</ns3:sup> = 18.32, p < 0.001), evidencing structural inequalities in adaptive capacity. A moderate positive correlation (ρ = 0.36, p = 0.003) was observed between climate perception and reported impacts. Conclusions Climate change is widely recognized across Lake Titicaca communities; however, adaptive capacity remains uneven due to disparities in institutional support, resources, and technical knowledge. Strengthening multi-level governance, participatory adaptation strategies, and transboundary cooperation is essential for improving resilience in Andean socio-ecological systems. </ns3:p>1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Impacts of Climate Change and its perception in communities surrounding Lake Titicaca, Peru-Bolivia.(Faculty of 1000, 2026-03-19)<ns3:p>Background Lake Titicaca underpins the livelihoods, culture, and ecosystems of high Andean Aymara and lakeside communities in Peru and Bolivia. Recent multi-year declines in lake level, rising temperatures, and greater climate variability threaten water supply, agriculture, fisheries, tourism, and public health. This study characterizes climate change impacts and local perceptions in lakeside sectors to inform adaptation and cross-border management. Methods A multidisciplinary, participatory approach combined: (1) exhaustive document review of physical and cultural drivers; (2) fieldwork (November 2024 and June 2025) in Quehuaya (Cohana Bay, Bolivia), Capachica (Puno Bay, Peru), Guaqui (Bolivia), and Puno urban area; and (3) participatory methods including community workshops with social mapping and surveys, six in-depth interviews, and a MINCETUR ecotourism seminar survey (n = 26). Data were triangulated with institutional meetings and synthesized quantitatively. Results Eighty-five percent of respondents reported observed climate change indicators; seventy-four percent noted decreased rainfall, and fifty-eight percent reported hotter days. Sectoral impacts included agriculture (61% affected; reduced yields and altered planting calendars), fishing (52% decline in species or volumes), livestock (50% impacts on pasture and water; 42% increased disease), and tourism (27–29% affected by reduced navigability and pollution). Fifty-three percent reported local adaptation actions (e.g., tolerant crops, water reservoirs, traditional practices), while external support from government or NGOs was limited (~18–19%). Primary needs were financing (76%), improved climate information (52%), and organizational strengthening (26%). Participatory mapping documented shoreline retreat and cultivation of exposed lakebeds. High perceived urgency and reported migration increases (53%) highlight socioeconomic vulnerability. Conclusions Communities around Lake Titicaca face a chronic water-deficit syndrome driven by climatic and local stressors, producing cascading ecological, economic, health, and cultural impacts. Reactive localized adaptations exist but are insufficient. Effective response requires integrated binational strategies: improved water storage and irrigation, wetland restoration, pollution control, real-time climate information, targeted financing, and strengthened institutional coordination.</ns3:p>1
