Preface
Prof. Hiromichi TOYODA, Conference Chair, on behalf of the Organizer
Almost one year had passed since we held the 1st International Conference on Arid Land (ICAL1) in Narita,
Japan. Although it was just immediately after the great East Japan earthquake (Mar. 11, 2011), the conference was truly
fruitful and productive. Continuous efforts are being taken on for reconstruction from the unheard-of disaster. Even inthis one year, the world has been changed with great rapidity. Particularly, countries located in desert and arid areas
receive considerable attention. Therefore, importance of studies on desert and arid land nowadays is much more realized.
The Conferences on Desert Technologies have been held for 9 times since 1990 addressing to naturalcharacteristics of desert and desertification area (e.g., climate, hydrology, and vegetation), mechanism of thedesertification, and its prevention methods. Although the conferences have been a great source of learning for
researchers from relevant countries contributing various knowledge and technologies with fruitful discussions, issues ofdesertification remain a main global concern resulting in necessity of further and continuous researches. Furthermore, theprevious conferences have often focused on technological aspects of the desertification and arid regions. Therefore,based on previous experience and accomplishment, and on the occasion of the 10th anniversary, the 10th Conference on
Desert Technologies (DT10) offered an opportunity of comprehensive discussion and extents fields of research including
natural, technological, human and social sciences towards overcoming constraints of the desertification. The DT10 was
held as the 1st International Conference on Arid Land (ICAL1). A record of DTs is listed the end of this preface. Theconference welcomes researchers who associate with deserts and arid regions from diverse aspects of sciences including
natural science and the humanities.
In this conference, there were 142 participants from 29 countries, while having 55 oral presentations and 46
poster presentations. As we could have the significant time and perform useful discussion with making a goodfriendships. As well as past DT conferences, we could be together in participation in various events and there could be
sufficient free time for informal discussions within the week. The friendship must have been deepened throughout thesediscussions. Also the mind must have been refreshed, the purpose could be sufficiently accomplished.
We hope, ICAL1 (DT10) would be the start of a new arid land research and interchange between natural scienceand the humanities.
We would like to thank you all for your participation in this conference and we would especially like to extend
our appreciation to all sponsors, co-operators and co-organizers.
