THE IMPACT OF sewage ON WATER QUALITY 

Addressing Major Contributors to Water Pollution

One of the major contributors to water pollution is, of course, sewage. For islands, addressing sewage management is often the most significant investment needed to mitigate pollution. These major sanitation projects do not offer a straightforward economic return. Instead, their justification often lies in their long-term benefits, such as preventing damage to nature, protecting marine life, and avoiding the economic costs related to tourism, fisheries, and the increased expense of importing food due to the loss of local fisheries.

Justifying Major Sanitation Investments

justifying major investments

long-term environmental benefits

  • Proper sanitation prevents extensive damage to marine ecosystems, which supports biodiversity and maintains the island’s natural beauty.

economic considerations:

  • The long-term economic benefits include safeguarding tourism and local fisheries, which are critical to the island’s economy.

funding needs

  • Such infrastructure projects typically require external funding, given their scale and complexity.

valuing natural assets

Attaching value to the island’s natural assets is crucial for justifying sanitation projects. This approach recognizes the intrinsic worth of natural resources and ecosystems, emphasizing their importance in sustaining both the environment and the economy. Tools such as Aquatrail and Marine Positive certification are valuable for calculating the cost-of-damage caused by water pollution. These tools provide a clearer understanding of the potential economic and environmental impacts, reinforcing the need for effective pollution management and preservation efforts.

Managing Runoff and Agricultural Pollutants

Runoff from agricultural activities is a critical issue, as it often carries pesticides and fertilizers into the sea. These chemicals can severely impact marine habitats.

  • Chemical Impact: Pesticides and fertilizers interfere with marine ecosystems, potentially leading to the loss of vital habitats and marine life.
  • Mitigation Strategies: Implementing best practices in agriculture, such as reducing chemical usage and improving land management, can help minimize the impact of runoff.

Stormwater Management

  • Pollutant Collection: Stormwater runoff collects debris and pollutants as it flows over land, which can then enter water bodies and affect water quality.
  • Effective Measures: Strategies such as rain gardens, permeable pavements, and efficient drainage systems can help manage stormwater and reduce pollution.

the challenge of behavioral change 

addressing littering and personal waste

Littering and the improper disposal of trash, garbage, and waste near or in the ocean are significant challenges that often require substantial behavioral change. To tackle these issues effectively, it’s crucial to focus on education and communication. Engaging the community through targeted educational campaigns can help shift attitudes and practices regarding waste disposal.

Promoting behavioral change involves not only informing residents about the environmental impacts of littering but also fostering a sense of responsibility and stewardship. Community involvement plays a key role in this process. For practical strategies on how to engage inhabitants and encourage responsible waste management, refer to the section on ‘Engage Your Inhabitants.’ By working together and committing to cleaner habits, we can significantly reduce the impact of littering on our oceans and surrounding environment.
