These proceedings gather presentations from the 13th Tunisia-Japan Symposium on Science, Society and Technology (TJASSST 2015), held in Tsukuba, Japan on February 23-25, 2016. The conference's focus was on the development of interdisciplinary approaches to sustainable society. In keeping with that goal, the book explores a broad range of topics in the environmental sciences, life science, food and agriculture, energy and materials, math and ICT, humanities and social sciences, and management and innovation. The respective chapters, all of which were written by respected experts, address the functionality and nutrition of food, plant biology, molecular biology, wastewater treatment, water resource management, hydrology, environmental assessment, solar cells, biofuels, nanotechnology, practical mathematics, information technology, social science, and socio-economic management. Accordingly, the proceedings offer a valuable resource for all researchers and students interested in contributing to sustainable development.
