(Extract from Introduction) The project, as proposed in the 1980 study by YTS/MMP, comprised 8 850 ha net of irrigated land supplemented by 2 675 ha of rainfed land at full development. The rainfed areas were not considered suitable for surface irrigation due primarily to topographic limitations. The scheme was designed to form the basis of the resettlement of nomads temporarily located at Dujuuma with a holding size of 1 ha per family. Overall management of the project would be by the Settlement Development Agency (SDA).

The principle objective of the Homboy Irrigation Scheme is to provide all participants with a permanent abode and the resources to sustain a reasonable standard of living. Since the potential participants, (i.e. the existing farmers, sedentary and semi sedentary families of nomadic origin, e.g. nomads from Dujuuma and possibly refugees from northern Somalia) represent a wide range of ability, experience and aptitude for irrigated arable farming, determining a farm organisation settlement suited to everyone and achieving this objective will not be easy. In proposing a form of development we have taken into account the human resources involved, the need for time to adapt and acclimatise to a more disciplined way of Life and the policies of the Government towards the disposition of these human resources. Three mainframes of development, a state farm, village collectives and cooperatives within village blocks have been considered.br The report consists of the following volumes:br strongVolume 1 :Soils/strong strongVolume 2 :Physical Planning/strong blockquote Part 1 : Villagisationbr Part 2 : Relocationbr Part 3 : Groundwaterbr Part 4 : Infrastructurebr Annex : Main Construction Works and Costs/blockquote strongVolume 3 - Agricultural Planning/strong blockquote Part 1: Agriculturebr Part 2: Organisation, Management and Implementationbr Part 3 : Operation and Maintenance of the Irrigation System.br Part 4 : Economic and Financial Studies /blockquote In addition to these Volumes, a number of supporting contract documents and an album of engineering drawings have already been submitted.br

(Extract from the Introduction)BR The present report describes the methods, findings and conclusions of the soil survey investigations, forming part of the Phase II studies which were carried out in the Homboy Irrigated Settlement Project Area. Chapter 1 gives an account of the general natural and human resources of the area and Chapter 2 describes the soils in more detail, drawing on information gained from the present survey and investigations. The principles and methods employed for arriving at the land suitability classification for the proposed development are described in Chapter 3, along with general guidelines as to suitability for rain fed agriculture. The findings, conclusions and recommendations of this study are presented in the andlsquoSummary and Conclusionsandrsquoat the beginning of the report.Br The Homboy Scheme is a large and complex development. In addition to extensive civil works the lives of more than 25,000 settlers presently residing at Dujuuma and over 8,000 local residents within the project area will be deeply affected. The physical planning necessary to ensure a smooth yet rapid development, while at the sane time, minimising hardship and unnecessary disturbance, has been studied in detail, and our proposals are presented in this volume. Parts 1, 2, 3 and 4 cover the important aspects of villagisation, the relocation of the settler-s and the infrastructure necessary to support both the domestic and scheme management requirements. A summary of costs is also included. The Annex describes the main construction works and again costs are included.

This volume gives results of a semi-detailed soil survey carried out over a total gross area of 9,559 ha of the Mogambo irrigation project area. The report aims to extend the results of earlier studies on soils in the area . This is achieved by a more detailed observation network of survey sites in the area in particular within the Juba alluvial sails (five sites/km2). It also provides more quantitative data on the soil chemical and physical properties as an additional aid in soil classification for planning the development of irrigation in the area. Soil units identified are described in terms of modal characteristics and the variation found within the unit with profile descriptions for a11 pits and selected auger holes included in Appendices II and III. The nature of the mapped boundaries is fully described. The land was classified making use of the United States Bureau of Reclamation (USBR) methods, modified to suit the conditions found in the area. Suitability for rice and for field crops other than rice were considered separately and special use Class 4 was used to indicate areas more suitable for sprinkler development. Limitations affecting land suitability are denoted by the use of suitable land class suffix letters.
