Peru has seen a sharp increase in major flooding, prolonged droughts and water scarcity of supplies in the dry season, negatively impacting agriculture, migration, conflict and economic growth in recent years. As 71% of the world's tropical glaciers are found in Peru these climatic changes affected the country profoundly leading to a decrease in the glacial surface and creating unstable lagoons also causing natural disasters such as alluvium landslides and deadly flash foods. Glacial melt is also disrupting water flow and quality, posing a threat to the flora and fauna that rely on freshwater environments. Unsustainable management of fragile glacier ecosystems is causing environmental degradation and biodiversity loss. To counteract many of these challenges and to safeguard the communities that are in peril, in 2011, the Government of Peru together with a number of stakeholders, initiated an intervention to sustainably manage more than 200 new lakes that affect directly populations in different cities in the Ancash, Cusco and Lima regions, Huaraz being one of the cities targeted. The project benefitted downstream communities and protected fragile high-altitude freshwater ecosystems. (1,2)

Project objectives

The city is located below Lake Palcacocha which is surrounded by the imposing white peaks of two glaciers in Peru’s Cordillera Blanca. A temperature rise of 0.5-0.8C between the 1970s and the 2000s has seen a third of Peru’s ice caps vanish in the last four decades. Around 50,000 people live in the danger zone of the lake which now bears the brunt of the glacial meltwater and subsequently of climate change. Glacial melt is disrupting water flow and quality, posing a threat to the flora and fauna that rely on freshwater environments. In 2011, Huaraz, along with other cities and towns in Peru, was included in a project that aimed at sustainable watershed management in glacial mountain ecosystems. More precisely the project addressed the following goals: 1. To protect fragile high-altitude freshwater ecosystems 2. To protect and restore wetlands by replanting native species, protecting grassland and forests around important spring water resources, fencing tributaries for restoration of vegetation, and planting native species on water banks to protect water resources 3. To train smallholder farmers to carry out sustainable farming practices including the sustainable use of water 4. To build and strengthen capacities for adaptation to climate change and the reduction of risks associated with the retreat of the glacier while taking advantage of the opportunities to manage its water resources - flood hazards and landslides 5. To promote climate-resilient livelihood strategies in combination with income diversification and strengthening capacity for planning and better risk management 6. To impact public policy (institutional and financial sustainability) (1,2,3)

Implementation activities

The intervention started to be implemented in 2011 and it had 2 phases: the first phase of the project took place between November 2011 and August 2015. It aimed to strengthen operational technical capacities in glacier monitoring and research to bring scientific knowledge closer to surrounding communities and provide information for their adaptation and vulnerability reduction. Likewise, facilitate the institutional conditions that guarantee the sustainability of such actions in the framework of adaptation to climate change. Efforts on risk reduction and climate change adaptation in the intervention zones of Ancash and Cusco and since this second phase also the Cañete basin in the region of Lima were continued and an additional focus has been drawn on opportunities provided by glacier shrinkage and lake formation for energy production, domestic supply, agriculture and tourism. In the second phase of the Glaciers Project, which ended in 2019 it was expected to consolidate the progress made in the first; in order to scale up successful measures, and continue to innovate strategies and intervention mechanisms. Throughout the 2 phases, a number of workshops were organised as well as vegetation cleaning and restoration, reforestation (in 2016, 20 km from Huaraz) and wetland reconstruction. (1,2,6)

Details on the roles of the organisations involved in the project

The project consists of a Peruvian part, coordinated by the NGO CARE Peru, and including local, regional and national authorities, and of a Swiss part (Swiss consortium ECS) led by the University of Zurich, and including Créalp, Meteodat GmbH, and EPFL. The expertise of the Swiss consortium is complemented by a pool of international experts in fields related to the project activities, which take over specific tasks according to the needs of the project. Both parts, the Swiss consortium and CARE, strictly collaborate in accordance with a master activity plan to efficiently achieve and disseminate the main objectives and results. The implementing partners were the following: CARE Peru, the project was also executed in consortium with the University of Zurich and the Government of Peru (Glaciology Unit of the National Water Authority), the regional Governments of Ancash, Cusco and Lima, Peru Ministry of Environment, Peru, Ministry of Economics and Finance, community-based organisations: communities of Cusco and the Nor Yauyos- Cochas Landscape Reserve in Cañete, Lima and Meteodat, the Alpine Environment Research Center (CREALP), and the Federal Polytechnic School of Lausanne (EPFL). The project was funded by the Swiss Agency for Development and Cooperation (SDC). (2,3)

Project implemented in response to ...

... an EU policy or strategy? No
... a national policy or strategy? Yes (Peru has a National Strategy on Climate Change - Estrategia nacional al cambio climatico (2015) as well as a National Environmental Action Plan - Plan nacional de acción ambiental (2011-2021) and both identify key climate risks for the country, such as glacial retreat and reduced access to the associated water resources, unusual variation of temperatures on land and in the sea, changing historical patterns of rainfall, rising sea levels, and the increased intensity and frequency of extreme weather events. The National Strategy on Climate Change (ENCC) 2015 updates and replaces the ENCC originally adopted in 2003. It reflects the commitment of the Peruvian State to take action on climate change in an integrated, cross-cutting and multi-sectoral manner. (1,5))
... a local policy or strategy? Yes (Yes, the project is named in the Ancash Regional Climate Change Strategy - Estrategia Regional de Cambio Climático de Ancash (Ancash is the region where Huaraz is located) for 2016-2021). The ERCC is a territorial management instrument that helps determine strategic interventions to identify the threats to which we are exposed, reduce the vulnerabilities that constitute us as a society and manage risk to take advantage of the opportunities that climate change brings.
