Confined within a sugarcane monoculture: A participatory assessment of water pollution and potential health risks in the community of El Tiple, Colombia.

Communities neighboring monoculture plantations are vulnerable to different forms of pollution associated with agro-industrial operations. Herein, we examine the case of El Tiple, a rural Afro descendant community embedded within one of the largest sugarcane plantations in the Americas. We implemented a participatory approach to assess water pollution, exposure via water ingestion, and non-carcinogenic health risks associated with the use of local water sources available to the community. We conducted household surveys to unveil demographic characteristics and family dynamics linked to water consumption. Additionally, we measured water quality parameters and assessed the concentration glyphosate, its major metabolite (aminomethylphosphonic acid) and metals and metalloids. Drinking water El Tiple households is sourced from three primary sources: the local aqueduct system, water delivery trucks, and private deep wells. Tests on water samples from both the local aqueduct and delivery trucks showed no traces of pesticides, metals, or metalloids surpassing regulatory limits set by Colombian or EPA standards. However, we found concentration of contaminants of primary concern, including mercury (up to 0.0052 ppm) and lead (up to 0.0375 ppm) that exceed the permissible regulatory thresholds in water from groundwater wells. Residents of the peripheric subdivisions of El Tiple are four times more reliant on well water extraction than residents of the central area of the town due to lack of access to public drinking water and sanitation infrastructure. Finally, adult women and school-age children have a higher health risk associated with exposure to local pollutants than adult men due to their constant presence in the town. We conclude that expanding the coverage of clean water and sanitation infrastructure to include all households of the community would be the most recommended measure to minimize exposure and risk via ingestion of water pollutants.

Water pollution and environmental policy in artisanal gold mining frontiers: The case of La Toma, Colombia.

Artisanal and small-scale gold mining (ASGM) is the largest anthropogenic source of mercury emissions globally. Concern over mercury pollution increases due to its long-term impacts on human health and aquatic and terrestrial ecosystems. Using a participatory research methodology, we gathered social and behavioral information regarding daily practices and water usage by an ASGM community in Suárez, Colombia. Based on this information, we identified 18 sampling sites of water sources commonly used by the community. The samples were analyzed for total mercury, total coliforms, pH, electrical conductivity, and total dissolved oxygen. Physicochemical and microbiological parameters from the water assessment were compared with the drinking water thresholds set by the Colombian regulatory agencies, the EPA, and the WHO. Our results showed that the majority of the samples do not meet one or more quality and safety standards. On average, the sampling sites showed total mercury levels below the regulatory limits; however, the data had considerable variability, and in many cases, individual observations fell above the maximum concentration limit for drinking water. We discuss these results within the larger framework of the regulatory gaps for human and environmental protection in ASGM contexts. The total lack of water, sanitation, and hygiene infrastructure, combined with the long-term consumption of sublethal doses of mercury and other water contaminants, constitutes a significant threat to the well-being of communities and territories that necessitates further research and intervention by institutional authorities.

Afrocolombian Struggles for Food, Land, and Culture: The Case of El Tiple.

El Tiple is one of many marginalized Afrodescendant communities confined within a green desert located in the southwest region of Colombia. This green desert is most widely known as the second-largest sugarcane monoculture field in the Americas. Herein, we describe a transdisciplinary and participatory effort to understand agroindustrial expansion in the region through the lens of the El Tiple community. Using qualitative and quantitative methodologies, we characterized the socioenvironmental context of El Tiple in terms of ethnography, autoethnography, social cartography, and ethnobotany. We implemented a participatory approach to codevelop a technology-assisted strategy for strengthening the community's small-scale farming activities. Our contextual analysis results show systemic food dispossession, which arises from several factors, including dramatic land transformation, rapid depletion and contamination of natural assets, and biodiversity loss. All these factors are associated with the presence of bordering sugarcane plantations. In collaboration with community members, we designed, constructed, and analyzed a greenhouse hydroponic cultivation system as an actionable means to gradually restore local production of food and medicinal plants for the community. Our transdisciplinary and participatory approach demonstrates how academics can partner with vulnerable communities in the coproduction of knowledge and solutions to pressing social needs.

No land for food: prevalence of food insecurity in ethnic communities enclosed by sugarcane monocrop in Colombia.

OBJECTIVES: To evaluate how the food systems in areas close to sugarcane monocrops influence the prevalence of food insecurity (FI) among three ethnic communities in the upper Cauca River basin of Colombia. METHODS: We developed a mixed methodology study at three rural zones located in the departments of Cauca and Valle del Cauca, Colombia, using a household survey to establish the level of FI, and semi-structured interviews with key community actors. RESULTS: These three ethnic communities have a high prevalence of FI (> 70%) that was found to be associated with economic income, social security, gender, the presence of minors in the home, refrigerator in operation and ownership of the land. Loss of food sovereignty was associated with the sale and rental of land. CONCLUSIONS: The sugarcane monocrop has contributed to environmental crises, spatial confinement and sociocultural disruption in ethnic territories; by renting, selling or leasing their land to the industrial production of sugarcane, traditional practices of food production and self-consumption have been profoundly transformed. Ethnic cultures are endangered, while food security and sovereignty of indigenous and black communities have been negatively affected.

Una mirada histórica y socio-ambiental para repensar y renombrar los conflictos entre comunidades étnicas del Alto Cauca, Colombia / A historical and socio-environmental look to rethink and to rename the conflict among the ethnic communities of Alto Cauca, Colombia

Resumen Este artículo analiza la conflictividad entre comunidades étnicas del Alto Cauca y sugiere que, antes que diferencias radicales basadas en la identidad étnica o cultural, el origen de estos conflictos se relaciona con empobrecimiento histórico de las comunidades rurales, el despojo de bienes ambientales como la tierra y el oro, y las dificultades irresueltas de la gobernabilidad multicultural en Colombia. Se argumenta que los conflictos del Alto Cauca deben considerarse socio-ambientales y su radio de análisis debe ampliarse más allá de los habitantes rurales pobres hacia otros actores e intereses que median en el despojo de las comunidades étnicas.

Abstract This article analyzes the conflict among ethnic communities of Alto Cauca and it suggests that, rather than radical differences based on ethnic or cultural identity, the origin of these conflicts is related to historical impoverishment of rural communities, the dispossession of environmental goods, such as the land, gold, and unresolved difficulties of multicultural governance in Colombia. It is argued that the conflicts, which take place in Alto Cauca should be considered social and environmental, and their area of analysis should be expanded beyond the rural poor inhabitants to other actors and interests that mediate the looting of ethnic communities.
