The Vital Role of Wastewater Treatment in Achieving Sustainability
As someone who’s passionate about creating a more sustainable future, I’ve long been fascinated by the critical role that wastewater treatment plays in advancing the United Nations Sustainable Development Goals (SDGs). It’s a topic that often flies under the radar, but when you dive into the details, the connections become crystal clear.
According to research from the University of Minnesota’s Sustainable Development Goals Initiative, wastewater treatment is directly linked to outcomes related to SDG 6 (Clean Water and Sanitation) and SDG 11 (Sustainable Cities and Communities). But the web of influence extends even further, touching on critical areas like human health, climate change, and biodiversity.
It’s a complex and multifaceted challenge, but one that I’m eager to unpack. After all, if we’re going to create a more sustainable world, we need to understand how the pieces fit together. And when it comes to wastewater treatment, the stakes couldn’t be higher.
Bridging the Gap: Conventional vs. Low-Tech Solutions
One of the key challenges in the world of wastewater treatment is the disconnect between conventional, energy-intensive systems and more accessible, low-tech solutions. As the research from the University of Minnesota reveals, conventional wastewater treatment is often impractical for rural and under-resourced communities, making it difficult to achieve universal access to safe and affordable sanitation.
Enter the world of wastewater treatment ponds – a low-tech, more sustainable alternative that has the potential to be leveraged globally. These natural systems harness the power of microbiological processes to treat wastewater, often with far less energy and infrastructure than their conventional counterparts.
The catch? The factors that control pond performance are still poorly understood, making it tricky to optimize their efficiency and ensure consistent, high-quality treatment. But that’s where the innovative research at the University of Minnesota comes into play.
A Microbiological Approach to Sustainable Solutions
Paige Novak, a professor in the Department of Civil, Environmental, and Geo-Engineering at the University of Minnesota, is leading a research project that takes a deep dive into the microbial world of wastewater treatment ponds. By studying the pond microbiome, Novak and her team aim to uncover the deterministic mechanisms that underpin treatment performance – information that could be a game-changer for communities around the globe.
“Studying the pond microbiome should allow us to determine the extent to which treatment performance is controlled by deterministic mechanisms and within those factors under engineering control, which are the most important,” Novak explains. “Such an approach is far easier than performing large-scale time- and space-intensive sampling campaigns, yet should yield similar information.”
In other words, by understanding the complex microbial dynamics at play in these ponds, the researchers can identify the key leverage points that can be engineered to optimize performance. It’s a holistic, science-based approach that has the potential to revolutionize the way we think about sustainable wastewater treatment solutions.
Expanding the Sustainability Horizon
But the impact of wastewater treatment doesn’t stop at SDG 6 and 11. As the University of Minnesota research highlights, these efforts also touch on SDG 13 (Climate Action) – a critical area in our rapidly changing world.
Mark Pereira, a professor in the Department of Epidemiology and Community Health at the University of Minnesota, is leading a project that examines the relationship between urban greenspaces and human health. By developing a novel “Urban Greenspace Access Score,” Pereira and his team aim to uncover the inequities in greenspace distribution and the associated implications for carbon sequestration, urban heat reduction, and biodiversity conservation.
“Living near or time spent in greenspace is associated with improved health,” Pereira notes. “This study has the potential to be a major methodological and research contribution by producing a robust, reproducible measurement that can be applied to other regions and being the first to examine greenspace inequities by neighborhood deprivation and historical redlining.”
The connections between wastewater treatment, urban greenspaces, and the broader sustainability agenda are profound. By considering these intersections, we can start to see the holistic, integrated nature of the Sustainable Development Goals – and the critical importance of addressing multiple fronts simultaneously.
Empowering Vulnerable Populations
As we delve deeper into the realm of sustainable development, it becomes increasingly clear that gender equality is a foundational prerequisite for progress. This is a key focus area for Lucy Mkandawire-Valhmu, a principal investigator from the University of Minnesota’s School of Nursing.
Mkandawire-Valhmu’s research project examines the experiences of gender-based violence (GBV) among refugee women of childbearing age in Malawi. By shedding light on this critical issue, the team aims to advance the development of healthcare interventions and policies that can promote and protect the health of women survivors in refugee camps and resettled communities.
“Gender equality is key to accomplishing all Sustainable Development Goals,” Mkandawire-Valhmu emphasizes. “GBV has important implications for maternal morbidity and mortality, and refugee women who flee to low-income countries like Malawi are faced with additional vulnerabilities.”
It’s a powerful reminder that sustainable development isn’t just about the environment or infrastructure – it’s about empowering the most vulnerable members of our global community. By addressing issues like gender-based violence, we can create more equitable, resilient societies that can truly thrive.
Cultivating a Climate of Change
As if the connections between wastewater treatment, urban greenspaces, and gender equality weren’t enough, the University of Minnesota’s SDG research also explores the critical issue of climate change education and awareness.
Jonna Korpi and Lisa Fitzpatrick, co-principal investigators from the Office of Sustainability and the Motion + Media Across Disciplines Lab at the University of Minnesota Duluth, are leading a project that aims to create an educational and artistic forum where individuals, students, and community members can explore their personal experiences with climate change and the emotional impact of these changes.
“Addressing climate change begins with talking about climate change topics openly, regularly, and in community,” Korpi and Fitzpatrick explain. “This work will add to our community’s body of climate change education, awareness-raising, and increase of human and natural capacity to address climate change impacts through mitigation, adaptation, and resilience.”
By providing spaces for reflection, integration of climate experiences into education, and artistic expression, this project taps into the human element of sustainability – the emotional, psychological, and cultural dimensions that are often overlooked in traditional approaches.
Building a Global Network of Sustainable Solutions
The University of Minnesota’s SDG research initiatives don’t stop at the borders of Minnesota or even the United States. They extend globally, with projects that aim to strengthen educational frameworks, foster international collaboration, and empower communities around the world.
For example, Dorcas Elisabeth Kunkel, a principal investigator from the University of Minnesota’s Academic Health Center and School of Nursing, is leading a project that assesses the relevancy of an existing set of core competencies for the training and practice of advanced practice nurses in primary healthcare contexts in Liberia and Sub-Saharan Africa.
“The FNP role has been shown to increase access to quality, safe primary care for populations that have not had this access before,” Kunkel explains. “The project supports outcomes for SDGs 3 and 4 by filling the profound gap that exists in the numbers of primary care providers in Liberia and across Sub-Saharan Africa.”
Meanwhile, Laura Rice, a principal investigator from the Department of Agricultural Education, Communications, and Marketing at the University of Minnesota, is fostering global collaboration through the development of strong communities of practice – both face-to-face and digital – among educators teaching about food security and sustainable agriculture.
“Teaching complex skills necessary for collaboration must begin in the educational system with highly-trained educators modeling the behaviors and teaching students the connection between local action and global solutions,” Rice emphasizes.
These projects underscore the interconnected nature of the Sustainable Development Goals and the importance of global partnerships in driving progress. By sharing knowledge, cultivating cross-cultural exchange, and empowering local communities, the University of Minnesota is paving the way for a more sustainable future that leaves no one behind.
