This cooperative effort is sponsored by the Japan International Cooperation Agency. After concluding an initial project in the Fergana Valley, where environmental conditions are suitable for successful silkworm rearing, University staff and local Uzbek counterparts undertook follow-up research in some of the harshest climate conditions of Uzbekistan. This was done to ascertain the extent to which introduced sericulture technology might be adopted anywhere within Uzbekistan. In 2013, this follow-up project was launched in four communities of Shavat County in Uzbekistan’s Khorezm Province. The Japanese Kinshu × Showa autumn-breed and Shungetsu × Hosho spring-breed of silkworms (Bombyx mori) were distributed to cocoon producers, who received regular technical visits from the experts dispatched from Japan. All project participants were asked for their appraisal of the two introduced silkworm breeds, and associated rearing systems. They reported that they were satisfied with the increased cocoon harvests, and expressed their interest in acquisition of Japanese mulberry (Morus alba) cultivars, which they felt may better sustain the large appetites of the introduced silkworm breeds. The respondents also especially liked a laborsaving technique that uses plastic netting for quick and safe removal of leftover mulberry leaves and silkworm feces from the rearing bed. The Uzbek government has requested continued technical cooperation with the University, emphasizing silkworm foundation stock and improved breeding lines.

Introduction The initial project “Revitalization of the Silk Road Silk Industry in Uzbekistan - Developing a Rural Income Raw silk supply to global silk garment markets has Generation Model by Improved Sericulture in Fergana Valley” declined drastically in recent years, due to the sharp decline in (September 2009-August 2012) led to a Memorandum of exports by the dominant producer, China. Chinese export of Understanding of technical cooperation that was signed at the raw silk contracted from 14,700 MT in 2002 to 7,700 MT in 10th Japan-Uzbekistan Joint Economic Conference in Tokyo 2012A). This decline was primarily due to dwindling (Yamada et al., 2012) between the State Joint-Stock Company family-based sericulture in the recently urbanized and Uzbekengilsanoat and the University. On this occasion, the industrialized Eastern Coast of China (Fan et al., 2008; Kubo, University recommended that its Uzbek partner establish 2014). This has resulted in rising raw silk prices B, C), offering young silkworms (Bombyx mori) communal rearing facilities a niche opportunity for the promotion of capital/land-saving to both increase cocoon productivity and to alleviate the work and labor-intensive family farm-based silk productionD). This burden on sericulturists. The University presented the same effort initially aims to furnish raw silk primarily for the recommendation to the director of the Uzbek Research domestic market. Then later on, when silk production Institute of Sericulture (URIS) while concluding fieldwork on techniques advanced sufficiently, export grade silk can be the project in August 2012. In December of that year, a provided to the quality-demanding international marketE, F). Cabinet Order was proclaimed which resulted in the With this backdrop, Tokyo University of Agriculture and establishment of 196 sericulture rearing facilities throughout Technology (hereinafter called the University) financed by the the country, each having the capacity to rear through pupation Japan International Cooperation Agency (JICA) has 50 to 100 boxes (29 grams of silkworm eggs per box) at a time undertakensericulture development projects in Uzbekistan (Madyarov and Umarov, 2013). The University was (Yamada et al., 2012; Japan International Cooperation Agency, informally invitedto manage two of these facilities.

The GIZ representative expressed his interest in assuming responsibility for the University’s initiative, if the University ever became unable to continue its work in Uzbekistan. GIZ’s goal would be to disseminate enhanced production of high-quality sericulture all over the country (Tokyo University of Fig. 1.
