In the arid regions of the world, maintaining economic and efficient crop production has been among
the most critical challenges. In this context, International Center for Agricultural Research in the Dry
Area (ICARDA) has been leading in research-for-development for improved management of scarce
water and land resources in the arid regions. In the new framework of the One CGIAR, the role of
ICARDA will be more indispensable as climate change will make considerable negative impact on
water resource availability and land sustainability in the dry areas. This review covers selected research
works pursued in irrigated, rainfed and agro-pastoral systems in cooperation with Tottori and other
Japanese Universities which represent longest history of cooperation between ICARDA and Japan.
The review is structured into sub-sections summarizing joint research on supplemental irrigation (SI)
for wheat cultivation to optimize water productivity in semi-arid region of West Asia and North Africa
(WANA), and rehabilitation of Jordan’s degraded agro-pastural lands with micro water harvesting
technology. Joint ICARDA and Japanese Universities’ research enhanced knowledge on the various
adaptation technologies’ effects on the soil-water-plant relationships, which supported the development
of tailored solutions and scaling strategies. The results are internationally recognized as contributions to
coping with scarce water resources and combating land degradation in arid and semi-arid environments.
