In the face of heatwaves and flooding, the Mexican Red Cross and the Zurich Climate Resilience Alliance are promoting local solutions to measure and strengthen community resilience
This is an adaptation of the original article written by Brenda Ávila Flores, Francisco Gabriel Reyes Gil, Jessica Rosales, Karla Hernandez, and Daniela Aguilar, published on December 15, 2025.Mexico is vulnerable to a variety of climate-related risks. These include droughts in the northern desert region, frosts in the north-west and north-east, heavy rainfall in the south, and tropical cyclones along the coast.According to Mexico’s National Centre for Disaster Prevention, approximately 80 per cent of disaster-related costs in Mexico between 2000 and 2022 were associated with water-related events. Flooding in the country has consistently caused damage to infrastructure, loss of life, displacement of communities and economic losses.Heat waves are also common in Mexico during the summer; however, the National Water Commission reports that most of the country has experienced above-average temperatures due to climate change.Two contrasting locations are Mexicali and Veracruz (Sotavento). These locations differ widely in terms of their geography, the threats they face, their vulnerabilities and their capacities.Mexicali is an urban centre on the northern border where people work in agriculture, industry and services, but face extreme heat, scarce rainfall and limited cooling options.In contrast, peri-urban and rural communities in the Sotavento region depend on agriculture, experience abundant rainfall and have access to river systems. However, they are constantly exposed to flooding and tropical cyclones.Climate Resilience Measurement for CommunitiesIn recent months, the Mexican Red Cross has used the Climate Resilience Measurement for Communities (CRMC) framework to guide a holistic and participatory process. The CRMC is a data-driven process that help communities evaluate and measure their resilience to climate hazards. And then, using the results, they can identify and implement resilience-building interventions and run additional measurements to track improvements.This measurement process included people's concerns about flooding in Veracruz communities, as well as the health implications of heat-related vector-borne diseases in Mexicali. The framework enables context-specific information on climate resilience to be obtained. By linking local knowledge with regional action, the Mexican Red Cross and its partners are addressing the immediate risks of extreme heat and flooding while also shaping systemic solutions for Mexico's future.The programme works with local populations to strengthen flood resilience at household and community levels by implementing interventions such as forming community brigades, developing family emergency plans and raising risk awareness through community resilience fairs.In both rural and urban areas, the Mexican Red Cross facilitates collaboration and integration with various sectors, including health, education, universities, and civil protection. This knowledge and experience is shared with communities, professionals, and political leaders, and is used to promote better laws, policies, and plans.Heat wavesIn recent years, Mexicali has experienced record temperatures in summer and an increasing number of heat waves. In 2024 alone, 47 deaths were directly attributed to extreme heat, marking a notable rise compared to previous years. This trend highlights the urgent need to address extreme heat as a critical public health issue.In Mexicali, families and workers depend on improved infrastructure and protective equipment, such as air conditioning, thermally insulated buildings and public cooling centres. This is not only to safeguard their health, but also to maintain their livelihoods and economic activities.However, air conditioning is not accessible to all, and marginalised communities often experience power outages, which increases their vulnerability. This highlights the need to explore affordable, accessible alternative cooling solutions to ensure heat protection for the most vulnerable. The assessment conducted through the CRMC identified opportunities to improve understanding of, and implementation of, Nature-Based Solutions (NbS), which protect, manage and restore ecosystems in order to address climate challenges.“There is no single approach to increasing climate resilience”.Mexican Red Cross Resilience Programme TeamHurricanes and stormsThe municipalities of the Sotavento region in Veracruz are regularly affected by hurricanes and tropical cyclones. These events bring heavy rainfall, which causes flooding in the basin and in low-lying areas. A key factor in the region's resilience is the presence of community brigades: local groups trained in disaster preparedness and response. The CRMC analysis identified an opportunity to strengthen these brigades by providing them with training and coordination, and by linking them to Early Warning Systems (EWS), which currently have limited reach at the local level. This will ensure that the most vulnerable groups receive timely information that will prompt life-saving actions and reduce losses and damage. “While each community has its own particular circumstances, the CRMC's research in multiple communities reveals trends in the impact of floods and extreme heat on social and economic structures”.Mexican Red Cross Resilience Programme TeamA collaborative approachThe CRMC process generates localised, up-to-date information that provides valuable insight into both gaps and opportunities.The Mexican Red Cross uses these findings to design and implement resilience actions that address real needs while strengthening existing capacities. Guided by the programme's objectives, the Mexican Red Cross works to integrate climate resilience with disaster risk management and expand access to SAT for floods and heat among the most vulnerable populations. These findings emphasise the importance of promoting context-specific resilience measures and influencing local and regional stakeholders to address shared challenges.In implementing the CRMC, the Mexican Red Cross adopted an innovative approach to data collection, adapted to urban contexts and designed to protect staff and volunteers in complex environments. Rather than conducting door-to-door surveys, resilience fairs were organised in Mexicali and Veracruz. These events brought community members together to participate actively in measuring the CRMC and in interactive activities designed to raise awareness of the risks in their territories. Additionally, data was collected through focus groups and interviews with key stakeholders. These included community leaders and government authorities from various civil protection organisations.This timely engagement enabled critical stakeholders and potential partners to become involved from the outset, thereby building trust and credibility. This engagement continues today as the Mexican Red Cross communicates the main results of the CRMC to decision-makers and communities, strengthening shared responsibility, empowering local actors to lead resilience efforts and ensuring that actions are appropriated by those most affected.To complement the actions of the Mexican Red Cross at a local level, the IFRC will work to ensure that the lessons learned from this initiative are recognised, adopted and replicated internationally in various strategic areas.
