This section of the Water Quality Data Book (Central Somalia) consists of the basic hydro-geochemical data used in the evaluation of the water quality in Central Somalia. It Contains existing information compiled from 28 sources and new data collected in 1985-86, Totaling 1,001 sets of data (data records). A computer data Base was established to process this large volume of information, which is stored on magnetic diskettes .A variety of computer programs were used to present the data in a uniform and meaningful manner, appropriate for easy consultation.

In line with the stipulations of Item II in Article II of the 'Agreement on Technical and Economic Cooperation' signed in Beijing on April 18, 1978, between the Government of the People's republic of China and the Government of the Somali Democratic Republic, the China National Complete Plant Export Corporation Dispatched a 'study group to Somalia in November, 1978, and, on April 28, 1979, signed in Mogadishu the andrdquoNotesandrdquoon the Talks about the Project of Well Drilling Tug Dher, Sanag, Bari and Nugal. The Notes stipulates that the Chinese Government would undertake the project of drilling 30 wells and of their wellhead assembly in the four northern regions of Somalia. Besides, China agreed to drill 6 we11s for Hargeisa water Supply expansion project, which was proposed by the Ministry of Mineral and Water Resources. This the report for the task

This End of Project report (EPR) summarizes the results of five years of intensive effort to investigate and to develop the groundwater resource potential of Somalia. The scarcity 0f dependable water supplies for the rural population and for their livestock is one of the most serious constraints to the economic development of the country. The Government of the Democratic Republic of Somalia (GDRS), in recognition of this problem, and in cooperation with the United States Agency for International Development ( U S A I D ) , estaSlished and funded the Comprehensive Groundwater Development Project (CGDP), This project was administered through the Water Development Agency (WDA) of the ministry of Minerals of Minerals and Water Resources, and was provided technical assistance by the firm of Louis Berger International, (LBI), in association with the Roscoe Moss Company (hereinafter referred to as LBII/RM). In addition 20 deveioping water supplies in the designated priority areas of the Bay, Hiran, Galgadud, and Mudug Regions (Figure) the overall purpose of the CGDP was to strengthen the WDA is capabiiity to construct,operate, and maintain rural water supply systems. As a further inducement to accomplish these goals, the CCDP was designed to be integrated with two existing USAID projectsthe Bay Region Agricultural Development project (BRAGB) and the Central Rangelands Development Project (CRDP).br; bVolumesb :ol li Executive Summary /li liGeneral Activities/li liHydrogeology/li liAppendix for volume 2/li liAppendices for volume 3/li /ol

During the course of the Comprehensive ground water development project (CGDP)a total of 118 boreholes were drilled in the Bay Region and Central Rangelands. 95 of these were in the Bay Region and 23 in the Central Rangelands. The data accumulated in this efort are subject of this volume of the report. Well data is presented in table 3.1.1 of the report. ol; bVolumes/b: br; li Executive Summary /li liGeneral Activities/li li; bHydrogeology/b; /li liAppendix for volume 2/li liAppendices for volume 3/li /ol

This report is as a result of a feasibilty study on watershed management in Selected sub-watersheds to carry ou planning and control design for th development ofd Somali irrigated horticultural gardens.

This technical report is a part of a series of reports to be prepared during the course of the GTZ Water Quality database project. The activities relate to the assessment of the geological and water quality conditions of the Central Somalia were carried out from March to July 1986

This publication presents a methodology to quantify yield response to water through aggregate components which form the "handles" to assess crop yields under both adequate and limited water supply. The method presented in part A takes into account maximum and actual crop yields as influenced by water deficits using yield response functions relating relative yield decrease and evapotranspiration deficits. Part B gives an account of water-related crop yield and quality information for 26 crops
