BMC Environmental Science is calling for submissions to our Collection on Nature-based solutions in waste-water management. This Collection aims to explore the applications, advancements, challenges, and mechanics of nature-based solutions in waste-water management.
Waste-water management represents a critical global challenge affecting many different aspects of human and environmental health. According to the latest estimates made by the United Nations, 44% of household waste-water generated globally is still being discarded without any treatment at all. Treating waste-water in centralized waste-water treatment plants with conventional technologies has limitations, as it can be energy-intensive and contribute to emissions of greenhouse gases such as nitrous oxide. Climate change-induced altered precipitation patterns and rising temperatures can also overwhelm the biological treatment of waste-water in centralized treatment plants by affecting the efficiency of microbial activity.
Nature-based solutions (NBS) in waste-water treatment can provide sustainable alternatives to conventional methods. While some of these solutions have been around for centuries, recent innovations have enhanced the efficiency, scalability, and effectiveness of using natural processes and ecosystems for waste-water treatment. For example, vertical flow constructed wetlands have minimized the footprint required for treatment, while natural-based filtration media such as coconut coir, biochar, and modified soils have helped enhance pollutant removal. Additionally, incorporating sensors, real-time data analysis, and automation into nature-based treatment systems has allowed for better optimization and management of the treatment process. These advancements signify a promising future for nature-based solutions in waste-water management, promoting ecological resilience, nutrient recycling, and sustainable water use.
We invite researchers and experts from environmental science, ecology, water resource management, and urban planning, to contribute their work related to NBS for waste-water management, including but not limited to:
- Innovations in the use of plants and microorganisms for waste-water treatment
- Technological advancements in emerging NBS technologies
- Design, implementation, and performance of NBS in waste-water treatment
- Role of NBS in waste-water management for urban and rural areas
- Impact on social-ecological systems of treating waste-water with NBS
- NBS and decentralized sanitation systems
- Waste-water source separation and NBS for waste-water treatment
- Frameworks and business models to support NBS adoption
- Planning and decision-making related to the implementation of NBS
This Collection supports and amplifies research related to SDG 3: Good Health and Well-being, SDG 6: Clean Water & Sanitation and, SDG 13: Climate Action.
