41st International Association for Hydro-Environment Engineering and Research (IAHR) World Congress (22-27 June 2025)
With the theme “Innovative Water Engineering for Sustainable Development”, the 41st IAHR World Congress (IAHR2025) will be held from 22-27 June 2025 at the Singapore EXPO. It aims to foster interdisciplinary dialogue, exchange cutting-edge knowledge, and explore innovative solutions to the world’s most pressing water-related challenges.
IAHR2025 will address the multi-faceted challenges posed by the dynamic intersection of water resources management, climate change adaptation, and intricate interplay between water, energy, food security, and nature. It shall provide a platform for experts, researchers and practitioners from around the world to converge and share cutting-edge insights, groundbreaking research, and new solutions in the field of water engineering to meet these challenges.
As countries and cities grapple with the effects of climate change, IAHR2025 will delve into innovative water engineering that adapts to the evolving challenges posed by a changing hydro-environment. IAHR2025 will also explore innovative concepts that alleviate the increasing pressure on the water-energy-food nexus and the intrinsic linkages between these vital resources. Understanding and optimising this nexus is crucial to fostering sustainable development. IAHR2025 shall promote the global exchange and collaboration for integrated approaches that maximise these interconnected resources.
By placing a spotlight on innovative water engineering, IAHR2025 aims to contribute to the advancement of the Sustainable Development Goals (SDGs) in both rural and urban environments, towards resilience societies for the well-bring of current and future generations.
IAHR2025 will be co-located with the Singapore International Water Week (SIWW) Spotlight 2025, a 2-day high-level Summit that will bring cities together to discuss how cities can adapt and build greater resilience to floods and extreme weather events.

SINGAPORE
Welcome to Singapore
Nestled at the southern tip of the Malay Peninsula, Singapore stands as a testament to the harmonious coexistence of diverse cultures, progressive urban development, and a rich tapestry of history. The island city-state prides itself as a pivotal trading hub and maritime port due to its strategic location in Southeast Asia.
Prominent initiatives such as NEWater and advancements in desalination technologies stand as testament to Singapore's steadfast commitment to overcoming its geographical challenges such as limited land area, lack of natural freshwater sources, and vulnerability to climate change. Through diversification and innovation, Singapore has positioned itself as a hub of ingenuity, spearheading global conversations and advancements in water management practices. This ongoing pursuit of innovation reaffirms Singapore's status as a beacon of resilience and progress on the international stage.
