JAPAN WATER FORUM
23 May 2024 - Bali, Indonesia❶ Promoting intergenerational initiatives forachieving sound water cycle

The Asia-Pacific Region faces mounting challenges related to climate change and maintaining a sound watercycle. In this dynamic landscape of water management,
youth engagement is increasingly crucial. The purposeof this session was to propose implementable strategies to meaningful youth engagement in resolving watercycle problems.

Challenges to co-work with local water management by youth
MOMBETSU Honoka & YAMAGUCHI Yuya,
Tomikawa High School
Digital Transformation and Nature-based Solution by Youth in Africa
NODA Eri, Global Environment Department,
Japanese International Cooperation Agency• Youth-led initiatives and intergenerational collaboration offer refined approaches for a sound water cycle.
• Volunteering opportunities are how most participants wish to be more engaged in the water sector❷ Climate-Water-Energy-Food-Ecology Systemof Systems

Water, energy, and food security, underpinned byhealthy ecosystems, are crucial for sustainable longterm economic growth and human wellbeing. This session promoted a new vision of water management, aiming at having an impact on the delivery of water to society, including human activities and ecosystem.

How Water is Different from Energy and Food?
OKI Taikan, Vice-President of the Japan Water
Forum (2024 Stockholm Water Prize)• Inexpensive cost of water should be ensured. We
use a lot of water every day.
• Virtual water trade can supplement water for foodproduction. Natural water scarcity can be alleviated.
• No country is economically challenged and waterscarce.

❸ Towards a circular economy transition
through safe collection, treatment and resource
recovery of wastewater and fecal sludge
Despite significant progress and an increasing awareness of the importance of sanitation, the world is far
from achieving the SDG 6 target of delivering sanitation
for all by 2030. Wastewater treatment and reuse is important in this regard. The session aimed to share experiences and best practices about the safe collection andtreatment of wastewater and fecal sludge.

Standardization of wastewater treatment systems
EBIE Yoshitaka, Chief Senior Researcher, National Institute for Environmental Studies• Standardization of ① effluent standards, ② structures or performance evaluation, ③ O&M and monitoring, ④ sludge collection, treatment and disposal, ⑤ license for technicians and service providers.
• Platform for standardization is recommended for industry-academia-government collaboration• Join the Water Environment Partnership in Asia, established by Japan’s Ministry of Environment in 2004.

Panel Discussion
NISHI Shi, Ministry of Land, Infrastructure,
Transport and Tourism• Decision to reuse more than 70% of treated fecal
sludge as fertilizer, for construction or other products.
• Safety is essential, as many people wrongly believethat sludge contains heavy metals or bad chemicals.
• Information needs to be made available for everyone
can make up their minds about the safety of reuse.

❸ Science-based policy to make DRR actionablefrom local to global

Water is closely linked to food and energy, and this water-food-energy nexus underpins the critical dimensions
comprising the quality of life. This session aimed to integrate knowledge across disciplines, create frameworks that link cutting-edge science and technology
with individual actions, and develop human resources
to drive these efforts forward.

KOIKE Toshio, Executive Director of ICHARM• Holistic impact assessment of climate change is necessary to identify adaptation options• Japan developed new river improvement plans fromobservation data and climate change prediction

NAKAMURA Keigo, Public Works Research Institute• Ecological flood control through wetland restoration,
including excavation for flood management• Novel technologies: airborne laser bathymetry, Visualization with game engine, environmental DNA

KAWASAKI Akiyuki, University of Tokyo• Vicious cycle of poverty and widening inequality has
been accelerated by flood disasters• Secondary benefits of disaster risk reduction are 2-to5 times higher than those of primary benefit
