Experts from industry, government, and academia with diverse backgrounds will be invited to hold 80-minute talk sessions on topics such as water, forests, weather, disasters, and planetary health. The topics of the talk session are expected to discuss the future and impact of climate change, the Anthropocene (the impact of human activities on nature), the significance of forest and water restoration, and technical measures (importance of measurement, data integration) to realize it based on evidence. Through discussions, we will let people know about the possibility of an integrated approach to decarbonization and solving water problems, and we will use this as a place to arouse interest in decarbonization and water issues.

Reports

【Reflection】
This program focused on the lesser-known relationship between water and forests, deepening discussions from technological, economic, and educational perspectives toward climate change mitigation and adaptation.
<Theme 1>What are the global challenges surrounding water and forests?
While water often seems abundant in daily life, the session highlighted the severe global water scarcity crisis. It addressed “hidden water” like water vapor and groundwater, and “hidden forests” with functions like disaster prevention and groundwater recharge. It demonstrated how visualization technologies for water and forests can lead to a renewed recognition of the value of natural capital.

<Theme 2>What Can Be Done Now, and What Is Needed Next?
Through case studies like flood simulations and drone measurements, discussions centered on how to link natural capital visualization to concrete countermeasures and conservation. The necessity of considering finance and cultural value was also emphasized.

<Theme 3> The Future We Should Aim For and Concrete Actions
The importance of integrated prediction and management technologies using diverse data was highlighted, along with the evaluation of multifaceted natural capital values such as water source conservation, disaster prevention, and CO2 absorption. Furthermore, the importance of consensus building among stakeholders, financial mechanisms, and decision-making that considers synergies and trade-offs was emphasized.

<Summary>
1. Visualization technologies for water and forests lead to renewed recognition of nature's value
2. Socioeconomic activities incorporating natural capital are required
3. An integrated approach encompassing both visible and invisible values is necessary

Addressing climate change necessitates collaboration among diverse stakeholders, considering synergies and trade-offs from technological, economic, and educational perspectives.
Finally, we emphasized the importance of “Think globally for earth, Act locally by people with together!”—thinking on a global scale while taking action locally. Water and forest issues are challenges relevant both globally and locally. We hope this program will heighten your interest and serve as a catalyst for action.

【Post EXPO Initiatives】
To achieve Nature Positive, the conservation, restoration, and sustainable use of natural capital—the foundation of socio-economic activities—are essential. Nature is the root of human activity, and it is vital to protect natural capital such as water and forests while supporting the livelihoods of those involved.
Furthermore, we must aim for sustainable development by integrating natural capital into socio-economic activities.

Through this program, we will continue to actively disseminate information to facilitate gatherings and deepen discussions among diverse stakeholders, thereby advancing the realization of “socioeconomic activities that incorporate natural capital.”

The Future of Earth and Biodiversity Week

The Untold Story of Water and Forests -Society and Innovation in the Era of Climate Change-

As a result of human economic activities since the Industrial Revolution, the destruction of the global environment has progressed, and problems such as global warming, intensification of disasters, and depletion of water resources are becoming more serious. In order to create a society in which nature and technology are in harmony, it is particularly necessary to take an integrated approach to solving decarbonization and water problems (shortages/disasters) together, and we aim to make people aware of the importance of these efforts through talk sessions, and to take them home and connect them to activities involving a wide variety of stakeholders.
