The Andes are particularly vulnerable to climate change given their role as a ¿water towers¿. In Argentina and Chile alone, more than 25 million people rely on water originating in the Andes. Yet, as noted by the Intergovernmental Panel on Climate Change (IPCC), the current pace and scope of adaptation are insufficient and the IPCC therefore deemed the Andes as a ¿high risk¿ region for livelihood and economies, due to projected future water scarcity. At the same time, the Andes are also a unique scientific laboratory, extending over almost 9000 km from the tropics and subtropics to mid- and high-latitude climates with a profound impact on global hydroclimate and high-impact weather events, thereby providing a unique set of challenges for impacts analysis and adaptation. Reducing the uncertainty surrounding future climate change impacts in the Andes, therefore, constitutes a major scientific challenge, which demands a close collaboration among international networks focused on Andean climate change. To address this challenge, we have created the ACCORD network of networks. The overarching goal of ACCORD is to build the first multidisciplinary network of networks focused on climate change across the Andes by leveraging transdisciplinary expertise of scientists from the largest international networks to produce scientific breakthroughs that have hitherto been elusive due to their interdisciplinary nature and international scope. ACCORD is funded by the NSF AccelNet program. ACCORD will also contribute to training the next generation of scientists that are capable of addressing scientific grand challenges, by involving students and early career scientists in our project. They will be exposed to interdisciplinary research abroad, help organize an international online seminar series, and participate in international summer schools and a high-resolution climate modeling workshop.

Los impactos del cambio climático, entre ellos considerablemente el retroceso glaciar, afectan la escorrentía y la calidad del agua. Por un lado, el drenaje ácido de roca deteriora gravemente el ciclo de agua, lo que afecta a las personas y los ecosistemas. En combinación con una gobernanza débil, fuertes desigualdades sociales y una demanda creciente de agua, las comunidades - a menudo marginadas - se enfrentan a riesgos cada vez mayores y una creciente inseguridad hídrica. Frente a ello, las investigaciones existentes suelen ser fragmentadas y estar desconectadas de la toma de decisión y necesidad locales. Este proyecto ofrece un marco transdisciplinario impulsado por universidades interesadas en tender puentes entre la ciencia y la política. Un grupo de investigadores de la Universidad de Zurich, Suiza y la Pontificia Universidad Católica del Perú analizará en conjunto con socios en el área de estudio diversas capacidades locales y estrategias de adaptación viables y localmente relevantes en respuesta al cambio climático para mejorar la seguridad hídrica a largo plazo. Este proyecto aborda tres paquetes de trabajo (PTs) interconectados que serán abordados de manera conjunta en estrecha colaboración entre la PUCP, UZH y socios locales. El PT1 busca cuantificar los impactos hidroclimáticos y socioeconómicos en un contexto del derretimiento glaciar. El PT2 analiza los factores que limitan el diseño y la implementación de estrategias de adaptación en un contexto de seguridad hídrica. Finalmente, mediante la integración de los modelos hidroclimáticos y económicos con conocimientos locales, el proyecto busca comprender los impactos sobre el agua y los límites de la adaptación, para diseñar estrategias de adaptación eficaces y localmente relevantes conjuntamente con las comunidades locales (PT3).

Global freshwater systems are critically threatened by environmental change and over-exploitation, stressing the need for novel, transformative solutions. Because of the diversity and complexity of social-hydrological systems, such solutions need to be informed by solid scientific evidence as well as tailored to local realities, knowledge, and practices. The current generation of reanalysis systems struggle to produce evidence that is accurate, tailored, and actionable at the local scale. We will develop a transformational framework to support local knowledge coproduction and its integration, together with existing and other emerging data sources, in global water system models. We will focus on three knowledge sources that are currently underrepresented in global models: nonstatutory monitoring, citizen observations, and local knowledge. Leveraging state-of-the-art technologies such as semantic data models and machine learning, we will develop novel knowledge integration workflows, with explicit tracking of epistemic and aleatoric uncertainties. Using a flexible modeling approach, we aim to produce a simulation system blueprint that is optimized for local and regional action, including the identification and prioritization of local knowledge gaps. This poses challenges not only of an ambitious scientific and technical nature but also in facilitating uptake, replication, and long-term sustainability. We have assembled a world-leading, interdisciplinary team and a global network of pilot sites to achieve this, by producing transdisciplinary science, developing transferable and scalable tools, and nurturing a global community of practice. If successful, it can produce a paradigm shift in data collection and knowledge co-production for freshwater reanalysis and its use.
