The development and dissemination of weather and climate information is crucial to improve people’s resilience and adaptability to climate variability and change. The impacts of climate variability and change are generally stronger for disadvantaged population groups due to their limited adaptive and coping capacities. For instance, smallholder farmers living in remote areas such as the southern Peruvian Andes suffer strongly from adverse weather and climatic events such as droughts or frost. The project Climandes aimed at providing high-quality climate services in support of the agricultural sector in southern Peru by implementing the guidelines of the Global Framework for Climate Services (GFCS). In Climandes, a two-fold challenge was tackled: the co-development of climate services by building up a continuous dialogue between the information provider (in this case the Peruvian national meteorological and hydrological service (NMHS)) and potential users; and the production of climate services through international cooperation. To this end, the NMHSs of Peru (SENAMHI) and Switzerland (MeteoSwiss) worked closely together to tackle issues ranging from the treatment of climate data to ensure the provision of reliable information to establishing continuous interaction with different user groups. In this paper, we postulate that this approach of close collaboration, the so-called twinning of the two NMHSs, was key for the projects’ success and contributed to strengthening the Peruvian NMHS institutionally and procedurally. This project overview guides its reader through the approach, main achievements, and conclusions regarding successes and challenges of the project, and reflects on some potential improvements for future initiatives.

Experiences from the disastrous 2016 El Niño revealed that its forecast, although available, was not known, accessed or understood by a large part of agricultural communities living in remote rural areas. This is all the more striking since these population groups are particularly vulnerable to adverse climate events as their livelihoods heavily depend on climate-sensitive agricultural production. In the framework of Climandes, a twinning project between the meteorological services of Peru and Switzerland, we implemented and evaluated the impact of community-based climate services that were co-developed with the target smallholder communities of the semi-arid highlands of the southern Peruvian Andes, where small-scale farmers are especially exposed to adverse climate events due to high inter-annual climate variability and weak socioeconomic capacities. In this chapter we analyse the project implementation through a socioeconomic lens. Research results generated alongside the project indicate that the well-directed user engagement resulted in a strong increase of trust in the weather service SENAMHI Peru and led to improved consideration of the information provided in the respective decision-making processes. We highlight the key steps that proved to be indispensable for the implementation of meaningful and sustainable climate services. The project outcomes point to the great and widely untapped potential of community-based climate services to reduce vulnerability and strengthen resilience of smallholder farmers in the face of changing climate conditions.

Livelihoods of rural populations, especially in developing countries, depend heavily on weather and climate. The use of climate information in decision-making by smallholder farmers, for example, may serve as a possible adaptation strategy to changing climate conditions, and promises potential economic benefits. Providing users with meaningful and timely climate information, however, is challenging and requires a nuanced understanding of the local cultural, social, agricultural and meteorological context. Despite this, the provision of climate information could constitute, especially in the most vulnerable settings, an important element of climate change adaption strategies, and form a key component of poverty alleviation efforts.

CLIMANDES is a pilot twinning project between the National Weather Services of Peru and Switzerland (SENAMHI and MeteoSwiss), developed within the Global Framework for Climate Services of the World Meteorological Organization (WMO). Split in two modules, CLIMANDES aims at improving education in meteorology and climatology in support of the WMO Regional Training Center in Peru, and introducing user-tailored climate services in two pilot regions in the Peruvian Andes. Four areas were prioritized in the first phase of CLIMANDES lasting from 2012 to 2015 to introduce climate services in Peru. A demand study identified the user needs of climate services and showed that climate information must be reliable, of high-quality, and precise. The information should be accessible and timely, understandable and applicable for the users’ specific needs. Second, the quality of climate data was enhanced through the establishment of quality control and homogenization procedures at SENAMHI. Specific training and application of the implemented methods at stations in the pilot regions was promoted to ensure the sustainability of the work. Third, the specific work on climate data enabled the creation of a webpage to disseminate climate indicators among users. The forth priority of the project enhanced the broad communication strategy of SENAMHI through creation of a specialized network of journalists, diverse climate forums, and the establishment of a user database. The efforts accomplished within CLIMANDES improved the quality of the climate services provided by SENAMHI. The project hence contributed successfully to higher awareness and higher confidence in the climate information by SENAMHI.
