INTRODUCTION 1. The Greater Mekong Sub-region East West Economic Corridor Agricultural Infrastructure Project (GMS-EWEC-AIP) will comprise improvements to productive rural infrastructure (PRI) and provide technical and advisory support to beneficiary communities in formation and strengthening of water user groups, technical support and capacity building for extension services and support in post harvest handling, product storage and marketing. It will provide project management support and capacity building for provincial and district level offices which will take a lead role in project implementation, in accordance with the Government’s decentralization policy of 2000. It is a sector project, and specific subprojects for the improvement of productive rural infrastructure in the two project provinces will be prepared and implemented. 2. This document provides an initial environmental examination of the Vapy Neua productive rural infrastructure subproject, a subproject under the GMS-EWEC-AIP involving irrigation scheme rehabilitation and agricultural access road improvement that has been selected as one of three representative subprojects under the project preparatory technical assistance (PPTA) for the PEP. Full subproject preparation, including feasibility study and safeguards assessment and planning, is included to demonstrate subproject preparation requirements. The IEE is prepared according to the ADB’s Safeguard Policy Statement of June 2009 and the EIA decree of April 2010. II. DESCRIPTION OF THE SUBPROJECT A. Subproject Scope 3. The Vapy Neua irrigation scheme is located in Vapy District and was constructed in 1997/98 through a joint initiative between the Department of Irrigation (DOA), and the Water Users Group (WUG). Like a considerable number of irrigation developments in Saravane Province the Scheme is a pumped scheme served by a station operating from a moored pontoon located on the Xe Done river, The total irrigable area (command area) is in the order of 220 ha and dry season irrigated rice is grown on 77 ha1. Improvements are to enable dry season cropping in the remaining 157ha and to include an extension of 50 ha. The improved scheme is to have a command are of 270ha, yielding both a wet and a dry season crop. 4. The Scheme water source is the Xe Done River which is a perennial river with regular fluctuations in water level throughout the year. The water source is undoubtedly assured and the potential demand has been estimated at 10 million cubic metres per annum. At some juncture the river basin management plan for the river demanded by the IWRM principles, and currently being developed by the DOWR. River level data to hand shows a fluctuation of only 0.3 m over the annual cycle. B. Present Condition and Characteristics of the Scheme 5. The Scheme has deteriorated and suffers from poor Operation and Maintenance (O&M). Some of the secondary
