Beyond water: impacts on health, education, food security and protection
What the analysis says: municipality by municipality
April is the month with the lowest level of impact during the quarter, with 1,282 people located in risk zones across the department. Soil and water bodies have not yet reached saturation levels.
May marks the critical point for piedmont municipalities. Saravena leads the risk levels with 19,171 exposed people, followed by Arauquita with 11,541 and Fortul with 6,651. During that month, 120 educational institutions and 9 rural health centers in the department are located within risk zones.
In June, the risk extends toward the savanna municipalities. The municipality of Arauca, with only 801 exposed people in May, rises to 9,995 people at risk in June. The department-wide figure reaches 41,988 people. Saravena maintains its 19,171 exposed people consistently throughout both months.
Beyond water: impacts on health, education, food security and protection
The analysis goes beyond the number of exposed people. It projects consequences for key sectors across the department: an expected increase in vector-borne diseases such as dengue and diarrheal illnesses in the health sector; interruption of classes for thousands of the 56,225 students enrolled in Arauca; threats to cacao, plantain, cassava and rice crops that sustain food security for rural households in Saravena, Arauquita, Tame, Fortul and Arauca; and increased risks of Gender-Based Violence and forced recruitment of minors within the protection sector.
The report also establishes concrete prevention recommendations by sector, ranging from crop management and livestock care to institutional protocols for prepositioning supplies, activating protection routes and preparing temporary shelters.
