He coordinates the Climate and Health Observatory, which has been&nbsp;operating&nbsp;for more than 15 years with the mission of&nbsp;monitoring&nbsp;the impacts of climate on health and developing adaptation strategies to address climate change. He is also co-principal investigator of the Harmonize Project, together with co-principal investigators from Cayetano Heredia University (Peru), the University of the Andes (Colombia), and the Dominican Institute of Meteorology (Dominican Republic). The Inter-American Institute for Global Change Research is a partner in this project led by the Barcelona Supercomputing&nbsp;Center&nbsp;and funded by the&nbsp;Wellcome&nbsp;Trust.&nbsp;<\/p>\n\n\n\n<p>In an interview available&nbsp;<a href=\"https:\/\/youtu.be\/_aOORKWCShc\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a>, Barcellos shared his experiences with the IAI. \u201cEverything that happens in the climate and the environment is reflected in health,\u201d says Barcellos, \u201cbut often indirectly and belatedly, mediated by social and economic factors. That complexity is what makes this work so challenging and so necessary.\u201d&nbsp;<\/p>\n\n\n\n<p><strong>Harmonize: building bridges between climate and health data<\/strong>&nbsp;<\/p>\n\n\n\n<p>The Harmonize project was born from a simple, yet&nbsp;ambitious idea: to create a common language between disciplines that rarely communicate with each other. Health, climate, land use, and economics often&nbsp;operate&nbsp;in isolation, but their interactions&nbsp;determine&nbsp;the lives of millions of people. Harmonize aims to break down these barriers by integrating data and knowledge from these fields, turning fragmented information into useful insights for public health and climate adaptation.&nbsp;&nbsp;<\/p>\n\n\n\n<p>For&nbsp;Fiocruz, Brazil&#8217;s leading health research institution, the project opened a new chapter in international collaboration. In collaboration with partners such as the Barcelona Supercomputing&nbsp;Center&nbsp;and the Inter-American Institute for Global Change Research,&nbsp;Fiocruz&nbsp;took on the challenge of developing predictive models and early warning systems that could&nbsp;anticipate&nbsp;risks before they become severe. It is not just about&nbsp;technology, but&nbsp;about creating a framework in which science serves communities in real time.&nbsp;<\/p>\n\n\n\n<p><strong>Regional impact from Brazil to the Andes and the Caribbean<\/strong>&nbsp;<\/p>\n\n\n\n<p>In Brazil, Harmonize focuses on two contrasting landscapes that reveal the country&#8217;s ecological and social diversity. The first is the Amazon basin, along the lower Tocantins River, where Chagas disease has become a pressing concern. Surprisingly, its transmission is linked to the cultivation of a\u00e7a\u00ed, a fruit that sustains local economies. The second is the semi-arid northeast, in the state of Para\u00edba, where prolonged droughts affect water availability and amplify the spread of vector-borne diseases. These regions are not far apart geographically, but they&nbsp;represent&nbsp;radically different realities\u2014an Amazon rainforest and a dry interior\u2014underscoring the need for integrated approaches such as One Health, which views human, animal, and environmental health as interconnected.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Beyond Brazil, Harmonize has fostered exchanges with Colombia, Peru, and the Dominican Republic. These collaborations reveal&nbsp;common challenges, such as limited access to health data, and shared opportunities, such as the availability of environmental information. They also highlight the diversity of Latin America\u2014from the Andes to the Caribbean and the Amazon\u2014and the need for solutions that respect local realities and&nbsp;leverage&nbsp;regional solidarity. For Barcellos, this is one of the project&#8217;s greatest achievements: creating a platform where countries learn from each other and build their resilience together.&nbsp;&nbsp;<\/p>\n\n\n\n<p><strong>Local participation and the way forward<\/strong>&nbsp;<\/p>\n\n\n\n<p>One of the guiding principles of the project is local participation. Barcellos insists that sustainability depends on listening to communities and involving them in decision-making. \u201cWe often arrive with preconceived ideas,\u201d he admits, \u201cbut the people on the ground have different priorities.\u201d In the Amazon, for example, residents alerted researchers to the growing importance of Chagas disease and its link to&nbsp;<em>a\u00e7a\u00ed<\/em>&nbsp;production. The challenge is delicate: protecting workers and consumers without undermining an economic activity that is vital to the region. This dialogue between science and society is the true \u201cco-production\u201d for Barcellos, a process in which solutions are built collaboratively rather than imposed from outside.&nbsp;&nbsp;<\/p>\n\n\n\n<p>The full interview (in Portuguese) is available&nbsp;<a href=\"https:\/\/youtu.be\/_aOORKWCShc\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a>.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-white-color has-text-color has-background has-link-color wp-element-button\" href=\"https:\/\/iai.int\/en\/boletin_425\/\" style=\"background-color:#638c3d\">Back to index<\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Christovam&nbsp;Barcellos is a researcher at the Oswaldo Cruz Foundation (Fiocruz), an institution that&nbsp;advises&nbsp;the Brazilian Ministry of Health on education, research, and technological development.
