Item THE IMPACT OF IMPROVED RURAL WATER SUPPLIES ON THE HAMAR AKD HUNR TRIBES OF SOUTH-WESTERN KORDOFAN - A GEOGRAPHICAL ANALYSIS(1971-12) ADEPETU, A. A.This thesis attempts geographical analysis of the impact of Sudan's deep bore programmes on water-deficient and under-developed South-Western Kordofan; it is based partly on existing published materials and partly but more importantly on extensive field investigation. The main finding is that deep bore programmes have helped to transform South-Western Kordofan socially and economically. Chapter one of the thesis outlines the various mechanisms through which this transformation has been achieved. In the analysis, use is made of Knetsch's approach of comparing conditions in two culturally and physically similar areas, one of which has been provided with a change-inducing factor, and of attributing any observed differences between the two areas to its Operation. Chapter two contains a short account of the resources of South-Western Kordofan, both physical and human. Particular attention is paid to solid geology, on which the occurrence of subsurface water depends, to the natura of the superficial deposits, and to rainfall and Vegetation. Conflicting principles of need and balanced exploitation of resources have characterized the allocation of boreholes in space and time. Chapter three examines the implications of such conflicting principles for the distribution pattern of deep bores in South-Western Kordofan. In this chapter the concept is introduced of 'usable land', which is a function of the availability of water; an attempt is also made to determine hypothetically what should be the appropriate maximum distance between one borehole and another that would make for the Optimum exploitation of agricultural land and grazing of South-Western Kordofan. The Impact of the deep bore programmes on South-Western Kordofan's major economic activities is dealt with in three chapters. Chapter four explains why pastoralists may continue to be migratory even when adequate perennial water supplies are available; it also suggests how the deep bore programmes may create more grazing problems unless accompanied by well organized pasture management. Chapter five shows that the cropped area has increased considerably since the borehole: programmes began, but because attitudes towards cultivation vary widely, it is not possible to determine the precise contribution made by the deep bare programes to the expansion in the area under cultivation. The increase in cropped area has led to a reduction in the area under ’gum-gardens', but this has not been accompanied by a decline in gum production. Chapter six explains why and asks whether the Arabs will continue to invest their efforts in gum tapping if other and more rewarding sources of employment are open to them. The distribution of Services is strongly influenced by the availability of water. Since the population size of a settlement is limited by the amount of water it can provide in the dry season, the question is posed in chapter seven whether every deep bore settlement will possess population large enough for the Optimum use of all essential Services. The thesis ends with a short chapter which review a the role which the deep bore programes can and should play in the future development of South-Western Kordofan.Item INTRA-URBAN POPULATION MOBILITY IN THE OLD CORE OF IBADAN CITY(1974-09) ADESINA, H. O.The interest of this thesis is in finding out whether or not there is any residential relocation in the old core of Ibadan city within the past five years (1968-1972): and if there is any, to find out the processes generating the movements. Consequently, there are two main parts to the study. The first part sought for the pattern and volume of residential relocation. It looked at the direction and distance of the movements, using an accounting model to represent the aggregate flows that were analysed. The model led to coming to grip the general structure of the movement flows, particularly the varying spatial distribution of the Population-turnover that the main focus of the thesis. The second section delt with the explanation of the variations of the Population-turnover and the reasons for movement were also sought. Firstly, an attempt was made to inductively establish the parameters of ‘strain’. The correlation and regression models were then applied to search for the relationship between these parameters and the movement rates. The procedures all confirmed that there is a singularly most important factor that can be used in the explanation of the variations in the Population-turnover. Since the importance of the perception of the people was brought out by the regression models used to explain the variations in the movement rates, the later part of the section was devoted at looking, into greater details, the ways in which the people perceive their environment. In conclusion the major findings of the study were summarized and the implication of the study for planning was suggested.Item A GEOGRAPHICAL ANALYSIS OF THE POPULATION AND RURAL ECONOMIC DEVELOPMENT IN THE MIDDLE BELT OF NIGERIA: A CASE STUDY FROM BIDA AND MINNA DIVISIONS OF NIGER PROVINCE(1972-12) ADENIYI, E. O.The main focus of the thesis is the examination of the factors responsible for rural economic development in a part of the Middle Belt of Nigeria. The discussion is based on the "land surplus" model and the approach is to regard population density and population growth as the independent variables which in their turn are major factors determining rural economic development in the middle Belt of Nigeria. The physical and human environment of the middle Belt and its changing economy from that of a lagging to a growing zone are discussed. The distribution, demographic and cultural characteristics of the population in different parts of the study area are shown to have influenced the socio-econonic organisation of agricultural land, labour, land use and crops grown. It is shown that the size of the population and density is below the Critical population density which the present System of land use can Support. The agricultural economy and new trends in agricultural production are discussed and it is shown that the production of food crops in the Middle Belt serves as an 'engine of growth’ (as does the production of export crops in other parts of Nigeria) in the Nigerian economy as it is a major source of food supply for the growing population and urbanization in Nigeria. The increasing integration of the Nigerian economy which has led to a greater development of the internal exchange economy in the country is shown to have aided the increasing commercialisation of food crop production in the area. In addition, population movements into the area has led to increased agricultural production. These developments have turned the Middle Belt from a lagging to a ’frontier zone’. In Order to realize the potentialities of the Middle Belt in Nigeria, a number of suggestions are made for the further development of the rural economy of the area.Item THE IMPACT OF MIGRATION ON THE RURAL ECONOMY OF OSHUN DIVISION OF WESTERN NIGERIA(1972-01) ADEGBOLA, O.This study attempts to describe and analyse the impact of migration on the rural economy of Oshun Division of Western Nigeria. The thesis is in three parts. The first is concerned with the growth of migration from about the beginning of the present century to the late 1950’s. It investigates the historical and economic bases of the spatial distributions of both the in- and the out- migrants and analyses the pattern of their flows. The second part is concerned with the impact of migration on the factors of production. It begins with a consideration of the conceptual framework which tries to see the migrant as an agent of change. The rate of migration in different parts of the Division is shown to have been responsible for significant socio-economic changes especially in respect of the demand for, the supply of and the use of land, labour and capital. It also explains the different trends of economic development in the Division. In the third part of the thesis, the role of migrant enterprise and leadership is appraised and found to be reflected in the diffusion of agricultural innovations and the flow of skills from the destination end of the migration to the Division. It is largely against this background that the observed higher production of migrants as well as their larger share in the non-agricultural activities is explained. It is argued that the migrants have been responsible for modifying traditional institutions such as those associated with marketing of products. It is also contended that the role of migrants singly or collectively has been an important factor in the provision of some social amenities and economic projects. Finally, the problems and the future prospects of migration in the Division are examined.
