World Water Day 2026 – Water & Gender
Where water flows, equality grows
The global water crisis affects everyone – but not equally.
Where people lack safe drinking water and sanitation close to home, inequalities flourish, with women and girls bearing the brunt.
They collect water.
They manage water.
They care for people made sick by unsafe water.
They lose time, health, safety, and opportunities.
And too often, the systems that govern water leave women and girls out of decision-making, leadership, funding and representation.
This makes the water crisis a women’s crisis.
We need a transformative, rights-based approach to solving these challenges, where women’s voices are heard and their agency recognized.
All women must be equitably represented at all levels of water leadership – helping design every pipe and policy.
And women must drive change in water as engineers, farmers, scientists, sanitation workers and community leaders.
As we face growing risks, from a changing climate and water-related disasters to financing shortfalls, from social norms to governance gaps, we need everybody to play their full part: managing water as a common good and building resilience for the future.
This includes engaging men and boys as allies in promoting safe water, sanitation and hygiene for all, and in challenging the norms and behaviours that hold women and girls back.
Only then can safe water services meet everyone’s needs – empowering women and girls to lead healthier, more fulfilled lives – and making water a force for sustainable development and gender equality that benefits us all.
On World Water Day 2026, let's explore the critical relationship between water, women, and gender equality.Organised by UN-Water.

IAH (Irish Group) Technical Discussion Meeting
Groundwater and coastal carbon dynamics. IAH Ireland Group Technical Discussion Group Meeting
Alex Cabral, Trinity College Dublin: Groundwater and coastal carbon dynamics
More details here: https://www.iah-ireland.org/upcoming-events/
This talk examines how groundwater transports carbon and nutrients from terrestrial landscapes to coastal marine waters, shaping water chemistry and greenhouse gas emissions. Such groundwater-driven fluxes are often difficult to detect but can represent a significant overlooked component of coastal carbon budgets. A combination of radioactive tracers and stable isotopes is used to identify hidden groundwater flow pathways and to quantify associated solute fluxes along the land–ocean continuum. The findings highlight how geological structure and hydrological connectivity regulate groundwater-derived carbon and nutrient inputs to coastal ecosystems, with implications for coastal biogeochemistry and primary productivity.Price: free

1-4 Jul 2026 – Barcelona (Spain)
Congreso Ibérico de Aguas Subterráneas
Iberic meeting of the Spanish and Portuguese IAH National Chapters. The Spanish Chapter of the International Association of Hydrogeologists (IAH-GE) is pleased to invite you to a new edition of the Iberian Congress on Groundwater (CIAS2026), which will be held in the city of Barcelona on 1, 2, 3 and 4 July 2026.
This edition is organised thanks to the joint efforts of the University of Barcelona and the Institute of Environmental Assessment and Water Research (IDAEA-CSIC). The Congress will take place at the Faculty of Earth Sciences of the University of Barcelona.
CIAS2026 continues a long-standing series of congresses aimed at highlighting the crucial role of hydrogeology within the overall hydrological cycle. Its main objective is to foster interaction among scientists, technicians, water managers, students and water professionals in general, encouraging the exchange of knowledge, experiences and shared challenges related to the study and sustainable management of groundwater.
The IAH-GE, as the Spanish representative of the International Association of Hydrogeologists promotes activities that strengthen knowledge transfer and technical and scientific debate. To this end, it organises meetings, publishes monographs and the journal Hydrogeology Journal, and encourages collective reflection through workshops, round tables and congresses such as CIAS2026. In this edition, the Portuguese Chapter of the IAH will also actively collaborate in the organisation of the Congress, reinforcing its Iberian and cross-border character.
Located on the Mediterranean coast and taking place in the summer season, CIAS2026 will also provide an excellent opportunity to enjoy the natural and cultural surroundings of Barcelona. We aim for this Congress to be not only a forum for knowledge, but also a space for inspiration and synergy.
For this edition, agreements will be established with various accommodation providers in the city to ensure that all those who usually attend IAH-GE congresses are able to come to Barcelona.Price: 175 € - 600 €
