Wastewater as a solution den. However, it is a resource and a hidden connector: from wastewater reuse to nutrient recovery, from renewable energy production to surveillance for public health and ecosystem protection. This event will explore how sustainable wastewater management and sanitation provision can deliver shared benefits for ecosystem protection, health, climate mitigation, and food system resilience. Convened by UNEP and key partners, this dialogue will demonstrate that investing in wastewater provides real solutions to global challenges: addressing water scarcity, producing renewable energy, recovering nutrients, strengthening health security, lowering climate emissions, and building resilient food systems. The event will also highlight UNEPโ€™s convening role and invite Member States and donors to contribute to scaling solutions that protect people, economies, and the planet. Conclusion โ€“ Call to Action We call on Member States, partners, and donors to work with UNEP in unlocking the hidden value of wastewater โ€“ investing in innovation, capacity, and scalable solutions that deliver benefits across health, climate, and food security. Organizer Walid Passas

#UNEA7 discussion on #wastewater #pollution. Excellent statement from Ambassador Peter Maddens on his solution (30 mins in) & my intervention on #SewageDiplomacy (50 mins in), about raw sewage release from diplomatic residences.

Great that #Belgium leading the way!

The UN Environment Assembly is where countries agree on how to tackle the worldโ€™s biggest environmental issues.

Since 2014, over 100 resolutions have advanced global action on climate, nature, pollution & a more resilient planet.

Stay tuned for #UNEA7!

Dr Sergiy Medinets: โ€œThere is an urgent need for an integrated nutrient management plan for Ukraine that wastes fewer nutrients and reduces the amount of synthetic fertiliser needed.โ€

An algal bloom on a nutrient enriched lake encroaches into the Nymphaea alba and Chara hispida beds, causing plant dieback. Your work will develop a novel, targeted analytical method to allow us to rapidly screen samples to determine the molecular composition of the dissolved organic nutrients in these and other waters. These provide a critically important but overlooked nutrient resource driving ecosystem damage and biodiversity decline in waterbodies. We currently lack a unified technique that can rapidly screen samples in a targeted manner. You'll likely be highly motivated, enjoy both field and laboratory work, and be a good analytical chemist with attention to detail who is keen to make your mark through novel method development. Give Ian a ring or send him an e.mail (ian.d.bull@bristol.ac.uk), or contact me here or via my e.mail penny.johnes@bristol.ac.uk. We have a large team on the ERC REFRESH programme that you will be joining, along with two other PhD students due to start at the same time. Great team and learning opportunities.
