Welcome Address
Prof. Hiromichi TOYODA, Conference Chair, on behalf of the Organizer
Welcome to Narita, Japan! It is a great pleasure to be able to hold the conference and I deeply appreciate yourparticipation through this occurred unheard-of earthquake disaster (Mar. 11, 2011). I heartily pray for early revival for all
suffered people who were attacked by East Japan earthquake disaster.
The Conferences on Desert Technologies have been held for 9 times since 1990 addressing to natural characteristics ofdesert and desertification area (e.g., climate, hydrology, and vegetation), mechanism of the desertification, 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 of desertification remain amain global concern resulting in necessity of further and continuous researches. Furthermore, the previous 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 DesertTechnologies (DT10) offers 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 is held as the1st International Conference on Arid Land (ICAL1). The conference welcomes researchers who associate with deserts
and arid regions from diverse aspects of sciences including natural science and the humanities.
In this conference, there are 142 participants from 29 countries, while having 55 oral presentations and 46 posterpresentations. As we could have the significant time and perform useful discussion with making a good friendships eachother. 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 could be deepened throughout thesediscussions. Also the mind could be 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 science andthe humanities.
We would like to thank you all for your participation in this conference and we would especially like to extend ourappreciation to all sponsors, co-operators and co-organizers.
