Introduction
In many African cities, rapid and unplanned urbanization exacerbates the problems of solid and liquid waste management. N’Djamena, the capital of Chad, is a prime example. In Toukra, located in the 9th district, the accumulation of household waste and the absence of a structured collection system create an unsanitary environment conducive to the proliferation of waterborne and vector-borne diseases. Among these, malaria remains the most concerning, causing significant human and economic losses every year.
Poor Waste Management in Toukra
In Toukra, illegal waste dumps are increasingly found near homes. Plastics, organic leftovers, and household waste accumulate without sorting or treatment. During the rainy season, these dumps block drainage channels, preventing water from flowing. Large areas of stagnant water form, increasing health risks. Due to the lack of an effective municipal system, residents are often forced to burn or abandon their waste in the open air, further aggravating pollution and unsanitary conditions.
Waste, Stagnant Water, and Malaria
Urban insalubrity and stagnant water promote the proliferation of Anopheles mosquitoes, the main vectors of malaria. Waste obstructing drainage channels creates breeding grounds where mosquitoes reproduce massively after each rainfall. Residents—especially children and pregnant women—become easy targets for the disease. This vicious cycle transforms an environmental problem into a genuine public health emergency.
Health and Socio-Economic Impacts
The high prevalence of malaria heavily impacts families in Toukra. Expenses for treatment and medication represent a significant burden for low-income households. The disease leads to school and work absenteeism, reducing economic productivity and further weakening families. Local health centers are frequently overwhelmed, limiting their ability to address other medical needs.
Solutions and Perspectives
Several measures can break this cycle. Raise community awareness about proper waste management and regular cleaning of surroundings. Implement a collection and recycling system (including composting) to reduce illegal dumps. Improve drainage and sanitation to prevent the accumulation of stagnant water. Strengthen partnerships between authorities, NGOs, and communities for sustainable, coordinated actions.
Conclusion
The case of Toukra shows that poor waste management is both an environmental and a public health issue. Fighting malaria requires more than just distributing mosquito nets: it involves maintaining a clean environment and effective sanitation. Only collective and sustained mobilization can reduce mosquito breeding sites, improve quality of life, and protect Toukra residents from this preventable disease.
