Ítem Community participation in landslide risk reduction: a case history from Central Andes, Peru(Springer Science and Business Media LLC, 2019-07-13) Jan Klimeš; Ana Marlene Rosario; Roque Vargas; Pavel Raška; Luis Vicuña; Christine JurtThis article describes the intertwined history of scientific research and landslide disaster risk reduction efforts in a small peasant community in the Rampac Grande of the Peruvian Andes. It was struck by a catastrophic landslide in 2009, claiming five fatalities and challenging local knowledge about landslide occurrence and mitigation practices. This article describes collaboration between a team of scientists, comprising both foreign and Peruvian experts and the local community, which started after the 2009 landslide and culminated during the disaster risk reduction (DRR) project which ran from 2016 to 2017. It illustrates the shift from refusing outside intervention to acceptance of the proposed measures and active community participation in their application and maintenance. This was achieved by rethinking the role of local and scientific knowledge during the process of DRR through enhanced communication and the appropriate use of the participative methods. Emphasis is placed on the crucial role played by community representative participation during formulation of the expected outcomes of the DRR, which leads to hazard reduction through the preparation of hazard maps and of the monitoring of landslide movement. Enhanced community development can also be evidenced by the construction of water tanks in the year following termination of the project. Despite the documented short-term success in landslide DRR, defining long-term exit strategy allowing the community to continue applying the measures with necessity of the minimum input from the outside actors is intrinsically difficult and still needs to be resolved.Ítem Landslide hazard assessment and risk reduction in the rural community of Rampac Grande, Cordillera Negra, Peru(Springer Science and Business Media LLC, 2023-12-22) Jan Klimeš; Jan Novotný; Jan Balek; Ana Marlene Rosario; Juan C. Torres-Lázaro; Roque Vargas; Darwing López; Yeny Obispo; Edgardo Roldán-Minaya; Adriana Caballero; Harrinson W. Jara; Hilbert Villafane; Enver MelgarejoThis article describes the landslide risk assessment of the Rampac Grande rural community in the Peruvian Andes, where an unexpectedly fast-moving landslide claimed fatalities in 2009. The study site represents a socially, culturally, and geologically challenging environment that limits applicable technical solutions for landslide risk reduction and demands a high level of community participation in all risk reduction steps. The performed landslide surface movement monitoring and slope stability calculations showed that the studied slopes are very close to failure. Therefore, the detailed hazard assessment was combined with field investigations of household vulnerabilities to perform a qualitative risk assessment in the zone around the 2009 catastrophic landslide. Results show that the high vulnerability, rather than the very high hazard, is responsible for assigning houses to the high-risk classes and education or improvement of the households’ income is key for further risk reduction. This underlines the importance of vulnerability reduction through the collaboration of the community members with external actors (e.g., Peruvian experts), which was interrupted by the COVID-19 pandemic restrictions. The context of the performed landslide risk assessment provides a summary of the 12-year-long involvement of different actors in the landslide risk reduction effort and the evaluation of the effectiveness of the previously adopted mitigation measures. It suggests that the community perspective on the mitigation measures and its risk perception changes determine the long-term risk reduction outcomes.
