Realizing a more sustainable supply and demand system for food and energy

The Institute of Food and Energy Systems (IFES) is a project-based research institute located within the Advanced Collaborative Research Organization for Smart Society (ACROSS) at Waseda University. The mission of IFES is to conduct and disseminate cutting-edge research that facilitates the realization of more sustainable food and energy systems both in Japan and internationally. To achieve this vision, IFES explores potential social mechanisms and technological developments that can foster integrated sustainable food and energy systems. We emphasize the balance between food, energy, the environment, and economies in our analysis and design of the systems.

Research themes

The IFES has two research themes: (1) food security and energy systems, and (2) health, nutrition, and energy systems. Specifically, we focus on the active use of renewable energy in the agri-food sectors, the adoption of more sustainable and healthy diets within limited energy resources, and the development of social mechanisms to support these goals. 

Food Security and Energy Systems

Facing a steady decline in agricultural workers in Japan, maintaining an adequate and stable food supply requires the country’s agriculture to shift towards larger-scale farming with higher levels of mechanization and automation. Accordingly, Japan’s agriculture will become increasingly energy-intensive, making energy systems more important for the sector. However, Japan’s energy self-sufficiency rate was only 12% in 2022. To raise energy self-sufficiency in Japan, it is crucial to increase the share of renewable energy use. However, increasing this share often leads to rising energy prices, which can result in higher costs for agricultural production and may accelerate the decline in agricultural profits and workers. Thus, there may be a trade-off between energy self-sufficiency and food self-sufficiency in Japan. Considering this potential trade-off, the IFES explores potential social mechanisms and technological developments that can foster more integrated and sustainable food and energy systems.

Health, Nutrition, and Energy Systems

In Japan, the rapidly declining birth rate and aging population make it essential to promote healthy diets and extend healthspan to secure a working population and reduce healthcare costs, thereby fostering a more sustainable society. Additionally, in the context of global efforts to combat climate change, there is a growing demand for more environmentally friendly diets. To achieve such diets in Japan, which heavily relies on imports for many food and energy resources, it is crucial to establish a more sustainable energy system for the agri-food sectors. This is important because electricity costs and food prices can influence people's diets and health. Therefore, the IFES explores food and energy systems that enhance human health and nutrition, alongside environmental considerations, as well as potential social mechanisms and technological developments that support these objectives.
