Exploring Resilience and Transformability of a River Basin in the Face of Socioeconomic and Ecological Crisis: an Example from the Amudarya River Basin, Central Asia Ecology and Society
Water from the Amudarya River is a vital and strategic resource for semi-arid Uzbekistan because of its heavy reliance on irrigated agriculture. The Uzbek water management regime, however, has proven to be rather reluctant to adapt to changing environmental and socio-political conditions despite recent massive pressures caused by political, environmental, or donor-induced developments in the region. The aim of this paper is to explore reasons for the low adaptability of the Uzbek water sector and assess implications for the resilience of the Uzbek social-ecological system (SES). By analyzing past losses of resilience as well as first attempts at institutional change in land and water management, we identify drivers as well as structural factors and...

The status of Kokandia Yefremova & Kriskovich (Hymenoptera: Eulophidae), with taxonomic notes on some related genera Naturalis
Gumovsky, A..
The diagnosis of the poorly known genus Kokandia Yefremova & Kriskovich, 1995 (based on the single species K. salsolicola, a parasitoid of the gall midge Desertovellum stackelbergi Mamaev) is clarified and the genus is re-described. This genus is not related to Omphale Haliday, 1833 (as it was stated in the original description), because the clypeus is not delimited. The type species of Kokandia resembles species of Closterocerus Westwood, 1833, in its habitual appearance, but differs by the absence of the subtorular grooves. The main autapomorphy of Kokandia is the wide peculiar adocular flange (not seen in any other known genus of the subfamily Entedoninae). Possible relationships of Kokandia with the genera Closterocerus, Pediobopsis Girault, 1913,...

Taxonomy and distribution of the Trifurcula (Glaucolepis) raikhonae group (Lepidoptera: Nepticulidae) Naturalis
Nieukerken, E.J. van; Purplesis, R..
Trifurcula (Glaucolepis) melanoptera sp. n. is described from southern Europe, where it is widespread. It is closely related to the Central Asian T. (Glaucolepis) raikhonae Puplesis, which is redescribed. Together they form the raikhonae species group. Sinopticula Yang is here synonymized with Glaucolepis Braun, its only species S. sinica Yang is tentatively regarded as closely related, if not conspecific with T. raikhonae. The distribution is mapped. On the basis of recent Chinese findings the larvae are assumed to be gall-makers on Prunus branches. Some phylogenetic and biogeographic remarks are given.

Sources of Agricultural Productivity Growth in Central Asia: The Case of Tajikistan and Uzbekistan AgEcon
Lerman, Zvi; Sedik, David J..
The paper examines agricultural production and productivity growth in two Central Asian countries – Tajikistan and Uzbekistan. Both countries are characterized by a significant shift of resources from the traditional Soviet model of collective agriculture to more market-compliant individual and family farming. In both countries, the beginning of the policy-driven switch to family farming around 1997 coincided with the beginning of recovery in agriculture, namely resumption of agricultural growth after a phase of transition decline since 1991. In addition to growth in total agricultural production, we also observe significant increases in productivity of both land and labor since 1997. These observations suggest that productivity growth may be attributable...

RELAXING CONTROL OVER THE CROPPING STRUCTURE: THE NEXT STEP FOR LAND REFORM IN UZBEKISTAN AgEcon
Chertovitsky, Aleksandr; Akbarov, Odil; Yakhshilikov, Yorbol.
Omnipresent control of Uzbekistan government in agriculture undermines land tenure security among the farmers and as result leads to low productivity and low incentives for investment into the land. In its turn low productivity in cotton farms worries the Uzbek policy makers on whether giving more freedom to 'private' farms will adversely alter vital production of cotton. In this study we hypothesized on opportunity of enhancing land tenure security in today's Uzbekistan without altering government's demand for cotton. Specifically we showed that relaxing requirement over the land occupation under cotton while leaving only government demand for output will result in freeing significant percentage of land area and consequently enhancing land [property]...
