As the rainy season approaches, waste dumped in rivers, drainage channels and open spaces is raising concerns in Blantyre, with environmental expert Charles Bakolo warning that unmanaged waste can block waterways, worsen flooding and pollute the environment.
Bakolo said improper disposal of household and commercial waste ontaminate water sources, damage soils and obstruct drainage systems.
He said heavy rainfall carry discarded waste downstream, spreading pollution to other communities and ecosystems while increasing flooding risks.
He also warned that poorly managed waste create conditions that attract disease vectors and contribute to the deterioration of urban environments.
According to Bakolo, the effects extend beyond the immediate surroundings, creating long-term environmental and economic costs when polluted ecosystems require restoration.

He stressed that waste does not disappear after being thrown away but remains in the environment and can eventually affect communities, natural resources and ecosystems.
Bakolo urged residents to stop using rivers and drainage channels as dumping sites and called on companies, particularly those producing and distributing packaged goods, to reduce waste and support recycling and responsible waste-management systems.
A block leader in Ndirande, Akika, called on local authorities to intensify public awareness campaigns so residents can learn practical ways of managing household waste.
He said some waste can be reused for purposes such as making manure instead of being dumped in rivers or open spaces.
However, resident Lawrence Magalasi said some communities continue to use rivers as dumping sites because they lack alternative waste-disposal options.
He said residents along the Nasolo River continue dumping household waste there because it has become the known disposal point in the area, while alternatives remain limited.
