| Özet: | Chapter Two: The African Giant Snail (Lissachatina fulica) in Cali and Valle del Cauca. This chapter highlights an environmental and public health issue involving pest control, scientific research, and community education. The African giant snail (Lissachatina fulica) is among the world’s most dangerous invasive species, listed as one of the 100 most harmful by the UICN. In Cali, climatic conditions such as humidity and seasonal rains, coupled with improper management of solid waste and debris, facilitate its proliferation. Since 2020, the Administrative Department of Environmental Management (DAGMA) has reported thousands of specimens collected in urban areas and neighborhoods such as Communes 6, 14, and 2. However, its expansion into rural areas poses an increasing threat to local ecosystems and agriculture. Contact with L. fulica can transmit parasites like Angiostrongylus spp., which cause severe diseases such as eosinophilic meningoencephalitis and abdominal angiostrongyliasis in humans, as well as pulmonary conditions in domestic animals. Additionally, the pest causes significant agricultural losses and disrupts ecosystems, displacing native species and affecting soil quality. Key factors driving its spread include an excess of decomposing organic matter, abandoned green spaces, and the use of soil or fertilizers lacking sanitary controls to prevent the presence of eggs. Community education and collection campaigns are crucial; however, effective control is limited in private properties and rural areas, where the snail finds ideal conditions for reproduction, laying between 900 and 1,200 eggs annually. Heat maps created by DAGMA and recent scientific studies reveal that historically affected communes include 5, 6, 8, 10, and 11. In Valle del Cauca, the pest has been detected in 35 municipalities, with higher prevalence in La Unión and Toro. Research by Aguilera-Arango et al. (2020) shows that distribution is influenced by altitude and climatic conditions, with low, humid areas being most vulnerable. The African giant snail has been classified as a pest in Colombia since 2008, and its control requires an integrated approach combining governmental, academic, and community efforts. Under the African Snail Research Project, the University of Santiago de Cali has developed and implemented tools like molecular tests to detect parasites and educational programs to raise public awareness. However, significant challenges persist, such as limited capacity to manage the pest in private and rural areas and the need for more data on the interaction between L. fulica and local microclimates. Resolution 654 by the Ministry of the Environment establishes guidelines for preventing and controlling this pest, but implementation requires specific resources, an updated database, and coordinated actions among various stakeholders. The presence of L. fulica in Cali and Valle del Cauca poses not only environmental and economic risks but also serious public health implications, as Angiostrongylus spp. are present in Cali’s communes. Control efforts must prioritize integrated strategies based on scientific research and community engagement to mitigate its impact and prevent further spread to new areas. |
