Impact of Participatory Irrigation Management (PIM) to Local Communities and Environment in Hop Tien Commune, Dong Hy
No full textThis case-study is designed to support the development of the Viet Nam – Netherlands Water Partnership on Water for Food and Ecosystems. The partnership is between Viet Nam’s Ministry of Agriculture and Rural Development (MARD) and the Netherlands Ministry of Agriculture, Nature and Food Quality (LNV). IUCN has been asked to coordinate the Partnership development process, including through undertaking study that will identify strategies for the management of water resources that balance agricultural production with the maintenance of the integrity of critical ecosystems that depend on adequate water flows. The case study is being carried out in Hop Tien commune, Dong Hy district, Thai Nguyen province, Vietnam. The purpose of the case study is to identify mechanisms based on that water resources management, which are traditionally approached as single purpose management regimes, should be enhanced to become more integrated, multi-stakeholder based management systems. At the irrigation scheme level, water resources management is considered as irrigation governance and management. The integrated approach is carried out with considerations of various interests such as irrigation, domestic water supply and fishery in Hop Tien commune. On the other hand, issues of saving water, water resources protection should be paid attention in the case study to ensure sustainable water resources development in the area

Modelling of hydrological response to climate change in glacierized Central Asian catchments
Full text linkThe arid lowlands of Central Asia are highly dependent on the water supplied by the Tien Shan mountains. Snow and ice storage make large contributions to current runoff, particularly in summer. Two runoff models with different temporal resolutions, HBV-ETH and OEZ, were applied in three glaciated catchments of the Tien Shan mountains. Scenario runs were produced for a climate change caused by the doubling of atmospheric CO2 as predicted by the GISS global circulation model and assuming a 50% reduction of glaciation extent, as well as a complete loss of glaciation. Agreement of the results was best for runs based on 50% glaciation loss, where both models predict an increase in spring and summer runoff compared to current levels. Scenarios for complete loss of glaciation predict an increase in spring runoff levels, followed by lower runoff levels for July and August. Model predictions differ concerning the degree of reduction of late summer runoff. These scenarios are sensitive to model simulation of basin precipitation, as well as to reduction of glaciation extent
Morphological variations of Thymus L. in the vegetation belts of the Tien Shan mountains (Central Asia)
Full text linkThis study demonstrated the correlation between Thymus L. life-forms and Tien Shan mountain conditions in which different vegetation belts can be located at different altitudes depending on a particular ridge. We selected four species of Thymus that are widespread in Tien Shan mountains (Thymus diminutus, T. dmitrievae, T. karatavicus, and T. seravschanicus). Eco-morphological and phytocenotic approaches were used to study the life-forms and biomorphs within the genus Thymus in this region. The module structure and sympodial axis were analyzed according to the slope steepness and stone/herbaceous covering. Acrotonic and basitonic module branching types are characteristics of dwarf shrub and dwarf subshrub life-forms, respectively. The dwarf shrub develops in open spaces in the steppe and forest and the dwarf subshrub develops in different vegetation belts: from steppe to alpine. Thymus dwarf shrub and dwarf subshrub life-forms were characterized by an implicitly polycentric biomorph type (mature plant comprising several closely located growth centers). Thymus species in the Tien Shan mountains exhibited morphological variability. We propose that the branching of Thymus plants can be used as an indicator of a specific vegetation belt in the Tien Shan mountains and to predict the behavior of other species with similar morphology.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Friction Observer and Compensation for Control of Robots with Joint Torque Measurement
No full textIn this paper we introduce a friction observer for robots with joint torque sensing (in particular for the DLR medical robot) in order to increase the positioning accuracy and the performance of torque control. The observer output corresponds to the low-pass filtered friction torque. It is used for friction compensation in conjunction with a MIMO controller designed for flexible joint arms. A passivity analysis is done for this friction compensation, allowing a Lyapunov based convergence analysis in the context of the nonlinear robot dynamics. For the complete controlled system, global asymptotic stability can be shown. Experimental results validate the practical efficiency of the approach. ©2008 IEEE
