Gully ecosystems are one of Barbados’ most valuable ecosystem types and can be found across much of the island. With an estimated length of ~457km, these ecosystems provide various services, including:

1. Aquifer recharge;
2. Habitat for native biodiversity;
3. Food supply; and 
4. Flood water control.

Unfortunately, these vital ecosystems are often mistreated and used to dump a wide range of solid and liquid wastes. The widespread issue of illegal dumping in and around gullies poses serious environmental and public health challenges, including:

1. Increased flood risk as accumulated waste forms blockages along the watercourse, impeding the natural flow of water;
2. Contamination of our groundwater sources, which threatens access to clean drinking water; 
3. Provides breeding conditions for disease-carrying vectors, such as rodents and mosquitoes which contributes to surges in their population; and consequently
4. Greater risk of vector-borne diseases spreading within nearby communities.

Notably, there has been a rise in the incidence of mosquito-borne diseases, which pose a serious threat to human life. This threat can be managed through the reduction and destruction of mosquito breeding sites. Breeding sites occur in places where water is collected undisturbed, providing ideal habitat for mosquitoes to breed and mature.

Illegal dumping in gullies specifically contributes to mosquito breeding by providing places for water to settle where mosquitoes lay their eggs. Because gullies are natural water courses, this makes it more likely for stagnant water to collect in waste materials that are not properly discarded, like containers, single-use plastics, buckets, tires, and other household items like large appliances.

Waste materials may also block the natural flow of water downstream after heavy rainfall, creating more areas for water to settle in the gully. The humid climate of gullies slows evaporation, causing breeding sites to thrive and exist for long periods. These types of waste materials provide a highly suitable habitat for Aedes aegypti mosquito larvae, which are vectors for dengue, Zika virus and Chikungunya. 

Mosquito control is both an environmental and public health issue that depends significantly on the help of the public. Here are some tips to reduce and destroy mosquito breeding grounds:

• Properly dispose of containers and other waste that can collect water 
• Keep outdoor and yard spaces clean
• Keep gutters clear and ensure plants have proper drainage
• Properly cover rainwater barrels and other water storage/ collection containers 
• Do not engage in illegal dumping of solid waste in or near gullies.

Protecting our gullies means protecting our health, our water, and our environment. Let’s work together to keep them clean. For more details and guidance on the management of solid waste around your environs you can contact:
