FIELD RECONNAISSANCE REPORT Kilombero Valley Irrigation Schemes: 10-14 December 2012 Technical Assistance to Support the Development of Irrigation and Rural Roads Infrastructure Project (IRRIP2) Prepared by: Keith F. Williams, P.E., Chief of Party Organization: CDM International, Inc.

ES EXECUTIVE SUMMARY ES.1 Background Under the U.S. Government’s Feed the Future (FTF) program, CDM International Inc. (CDM Smith) is implementing USAID/Tanzania’s Technical Assistance to Support the Development of Irrigation and Rural Roads Infrastructure Project (IRRIP21). Among other activities, IRRIP2 is supporting the development of irrigation schemes in the Kilombero district of Morogoro region. This report covers the activities and findings of a week-long field trip to the four IRRIP 2 irrigation areas in the Kilombero Valley between 10 and 14 December 2012. Each project area was visited and meetings held with all the key village councils. The Zonal Irrigation Office (ZIO) within the Ministry of Agriculture, Food Security and Cooperatives (MAFC) generated rapid appraisal documents for each of the schemes between 2006 and 2010. The objective of this field visit was to establish whether the land identified for inclusion in the four schemes remains available and to confirm the villagers desire to have access to irrigation water. The team included the CDM Smith Irrigation Head, the ZIO counterpart Irrigation Engineer, the ZIO surveyor responsible for much of the original scheme identification and the Kilombero District Irrigation Engineer. ES.2 Findings Without exception, at all the villages we visited, the farmers were enthusiastic about the prospect of having their lands included within an irrigation project and were keen to point out where additional lands might also be incorporated within the schemes. The status of a number of private investors with land holdings within the irrigation areas requires confirmation and a decision needs to be taken whether to include or exclude them from the schemes. Ideally they will not be excluded, but must agree to contribute to the upkeep and operation of the scheme and will be responsible for developing the irrigation distribution system within their own lands. The area of Mpanga-Ngalimila scheme appears to have been incorrectly recorded in the original rapid appraisal document, reducing the area from the initial estimate of 31,500 ha to 21,500 ha. The available area at this scheme has been further reduced by the newly defined Ramsar site boundary which reduces the available area to 12,776 ha if the Ramsar site boundary is ratified. The catchment area of the Udagaji River is only 25 km2. This is wholly inadequate to service the irrigation needs of the Udagaji scheme as envisaged by ZIO. Surplus water is however available from the Kihansi River and the potential for transferring water to supplement Udagaji water will be explored. The airfield operated by the Tanzania Electric Supply Company (TANESCO) which services the Kihansi hydro-electric scheme is fully within the proposed Mgugwe project area. 1 A closely related but contractually separate project, “Engineering Services for the Tanzania Irrigation and Rural Roads Infrastructure Project”, is undertaken concurrently by CDM International Inc. and is referred to for convenience as IRRIP1. FIELD RECONNAISSANCE REPORT – KILOMBERO VALLEY IRRIGATION SCHEMES ES-1 The scheme lands identified by ZIO are summarized below. The summary includes the initial areas as declared by ZIO in their rapid appraisal documents and our best estimate of the areas actually developable within the ZIO boundaries. We have also included the additional areas identified by the villagers for inclusion (in part or in whole) within the individual schemes.

Their availability also needs to be confirmed with the Land Use Planning Commission Of the 43,000 ha identified by ZIO, approximately 24,034 ha gross (20,028 ha net irrigable land) appears to be available from first estimates. A further 8,348 ha (7,453 ha net) may be available surrounding the schemes, subject to status confirmation through the Ministry of Land (MoL), National Land Use Planning Commission (NLUPC).
