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
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.
(Extract from the SUMMARY )Br This note considers the consequences of using the rice milling facilities recently constructed at the Fanoole Rice Project (FRP) to mill rice produced on the Mogambo. Irrigation Project (MIP) as an alternative to providing this project with its own milling facilities. The following main conclusions are reached: br (i) The processing capacity at FRP is insufficient to handle the entire crop production from the Mogambo Project. br (II) The comparison of capital and running costs of the two alternatives given below clearly indicates the advantages of a separate mill for Mogambo. br
(Extract from Introduction)The project was concerned with the operation of the hydrometric network of river level and flow gauging stations on the two main perennial watercourses of Southern Somalia, the Juba and Shebelli rivers, The project was initiated following a request by the Somali Government for assistance to bridge the gap between the end of a FA0 funded project (FAO/TCP/SOM 8906 + 0104) in 1980/81 and the proposed establishment of the national 'Water Centre', part of a UNDP 'IFF country programme originally scheduled for 1985. A joint proposal (April 1983) by Sir M. MacDonald and Partners (MMP), and the Institute of Hydrology (IOH) was accepted by the Overseas Development Administration (ODA), and the project commenced in November 1983
This report contains copies of the addendum covering the soil moisture retention results for the Farjano Settlement prject. The addendum comprises the following:ol li4.6.3 : Analytical and Field Data. This section supersedes the section 4.6.3 bound into the April 1985 report. /li; liTable 4.7 : Soil Moisture Retention Properties. New table. /li; liTable 4.8 : Soil Moisture Characteristics. An amended version of Table 4.7 in the April 1985 report./li; li Figures 4.3, 4.4 and 4.5 : Soil Moisture Characteristics. New figures. /li; liAppendix C : Soil Profile Descriptions./li; /ol
(Extract From introduction)This volume contains hydrographs of estimated daily flows (discharges) at selected gauging stations on the Jubba and Shebelli rivers for varying periods between 1951 and 1989. It is intended to be a companion volume to the Hydrometric Data Book', but for completeness and ease of reference much of the Introduction to the Data Book is repeated here. All original data has been checked, with errors corrected and missing values in filled where possible. Figure 1 shows the locations of the gauging stations and Table 1 summarizes their main hydrological characteristics
(Extract From Introduction)This land evaluation of the Farjano Settlement Project in the Lower Shabeelle Region of Somalia examined 16 000 hectares of alluvial soils. The evaluation was requested by UNHCR with the aim of locating land suitable for semimechanised rainfed (dryland) agriculture on which refugee settlers will become farmers, under the direction of a.farm management system that provides land preparation and planting services. The evaluation was also to examine the land suitability for settlement location, forestry and small-scale irrigation. A topographic survey was to be carried out to provide a contoured base map, and an additional topographicai survey was requested of the Farjano village irrigated farm (Sheikh Mohammed Hikam).
The comperehensive groundwater development project (CGDP) has been in progress since July 1981 under the Water development Agency of the Ministry of Minerals and Water Resources, Somali Democratic Republic. Originally it was scheduled to end in 1984, the project was extended until July, 1986. This interim report provides an update of project activities from July 1984 to July 1985. The report covers six of the project components concerned:ol; liDrilling program/li; liHydrogeology or data collected/li; liInstitutional support/li; liPrivate sector study/li; liRecomended programs/li; liDemobilization./li; /ol Volumes:ol li Executive Summary /li liGeneral Activities/li liHydrogeology/li liAppendix for volume 2/li liAppendices for volume 3/li /ol
(Extract from the executive Sumary)With the construction of the Mogambo Irrigation Project well underway arid the Agricultural Management Contract not yet awarded, a detailed planning study of both the agricultural operations end mechanisation required for the project became critical. This report reviews the original proposals contained in the previous studies and makes recommendations on agricultural operations, mechanisation for agriculture and operating and maintenance, traiisport, workshops, and management and staffing.
This report consists of the following annexes: br Annex VI - Human Resourcesbr Annex VII - Financial Analysisbr Annex VIII - Economic Analysisbr Annex IX - Management Unitbr
This report represents the findings of the Feasibility Study for Rehabilitation of the Jowhar Sugar Estate and Factory. Supporting data and more detailed presentations can. be found in the report annexes presented in separate volumes
This Annex is divided into five sections :-br In Section A (Water resources) we examine the problems of water availability and water quality, both of which are significant in terms of reduced cane yields. Possible solutions to the problem of dry season water shortages are discussed. Br Sections B (irrigation) and C (Drainage) deal with the existing irrigation and drainage systems and describe the alternative ways in which improvements can be made. The proposed rehabilitation measures are discussed in detail. Details of the investigative work carried out on the Estate during the fieldwork phase are presented. BR Section D (Operation and maintenance) discusses the requirements for operation and maintenance of the rehabilitated scheme and presents details of staffing and plant. BR In Section E (Costs) we present the cost estimates of the proposed rehabilitation measures, and recurrent costs for operation and maintenance.
