and fire but only under conditions of lenient grazing. The significant
determinants of shrub population dynamics, in descending order of importance,
are: grazing pressure, fire frequency, initial shrub cover, browsing pressure
and annual rainfall. Much of the effect of grazing was through its negative
influence on fire frequency. The results support a grazing-fire-encroachment
positive feed-back loop. Intraspecific competition among shrubs was strong in
the later stages of encroachment, and when rainfall was below 600 mm. This
competition, in association with droughts, countered the positive feedback chain
causing population crashes among shrubs and grazing animals. Browsing was only
important in suppressing the initial recruitment of shrubs. The implications
for savanna dynamics under various land-uses are discussed.Master of Science.

Notes : The purpose of this study was to survey the resource base available and
the "objectives of the populations involved" in the administrative areas around
Mjanyana with particular reference to livestock production. Random samples were
drawn from households in each of the five administrative areas namely, Debera,
Tora, Xonya, Mjanyana and Quluqu. Fieldwork in the form of questionnaire survey
was undertaken in the Debera administrative area. Numerous informal discussions
were held with rural farmers, tribal authorities, agriculture officers and other
governmental officers in an attempt to verify the "felt needs". The report
contains a description of the physical environment, an overview of the human
factors such as demography, land allocations, agricultural assets, production,
physical and social infrastructure, non-agricultural incomes and felt needs of
the area as a whole. See ref. I.D. no: 2339.

Notes : The purpose of the study was to 1. investigate the constraints to the
production, harvesting and consumption of fish at subsistence level and to
devise means to push them back; 2. harvest existing fish resources and improve
the stocks to provide the basis of a commercial fishing industry; and 3. develop
methods to increase production beyond the limits set by existing water bodies
and populations. A complete list of all water bodies in the Ciskei was drawn up
from secondary sources and information, and quantitatively evaluated according
to: a. volume and quality of water; b. existing fish populations; c. optimum
use of individual bodies of water; and d. cost estimates of achieving optimum
use. Fish consumption is entrenched in rural groups of the Xhosas. There is
eagerness among rural communities to obtain supplies of fish species tested in
the market survey, the "moggel". This was the result of lack of fresh water
fish or meat in the rural areas, which is the outcome of the poorly developed
distribution networks in the rural areas. The report also contains information
on integrated production systems of maize, lucerne, vegetables, livestock and
fish. See ref. I.D. no: 2339.

Notes : The purpose was to examine black family life in Southern Africa. The
study was conducted through literature review. The report focuses on the
networks of black families and is structured around pervasive notions of Ubuntu
(humanity) frequently given by informants in response to questions about support
and mutual assistance. It emphasizes the importance placed on mutual assistance
by the people whose lives are documented. Through the discussion of formal
organisations created for assistance and of ideational constraints of kinship,
friendship and neighbourhood, the report addresses the question of how support
mechanisms are activated and maintained. This report is obtainable at the
University of Port Elizabeth. See ID ref. no. 2339.

Keywords : SOIL EROSION; LAND USE; SOIL CONSERVATION; CONSERVATION; EROSION
Notes : Recent years gave witnessed a remarkable quickening of public interest
in soil conservation. It is widely realised today that soil erosion is
everybody's problem. The soil Conservation Act, no 45 of 1946 has been placed
on the statute book and came into operation in October 1946. The Soil
Conservation Board provided by this Act has been constituted and applications
from farmers for the proclamation of Soil Conservation Districts are pouring in.
Steps have also been initiated and are well advanced, to build up a strong field
conservation service - known as the Division of Soil Conservation and Extension
- which is the first essential to the success of the whole campaign. In view of
the numerous requests that are constantly being received for enlightenment as to
what has been, is being and will be done, it seems appropriate at this stage to
issue for public information a broad review of the whole position, with
particular reference to recent developments and the contemplated programme of
action. This review deals only with the sphere of activities for which the
Deaprtment of Agriculture, and more particularly the Division of Soil
Conservation and Extension, is responsible.

Notes : The author begins by providing a brief background on the physical and
human context within which the development of farming in the Union must be
visualised. It is evident that the Union cannot be regarded as richly endowed
from an agricultural point of view, but this does not detract from the fact that
farming is the direct source of livelihood for 31 per cent of the white
population and about 78% of the black population. Nor does it detract from the
vital role that farming has to play in feeding the nation and supplying raw
materials for the manufacturing industries. A brief account is then given
entitled: 'An era of land exploitation'. The 'menace of soil erosion' is then
dealt with, followed by the 'new era of soil conservation'. The author then
deals with State action to date, which he follows up with the situation as it is
today. He then suggests a plan of action. He describes the field 'conservation
service', and provides a 'home economics' section. Finally, the author deals
with soil conservation.

Notes : This publication is, in effect, a revised and expanded edition of the
brochure issued by the same author in 1948 entitled: "Land Utilisation and Soil
Conservation in the Union of South Africa. The first few chapters of this
publication are concerned with background material and follow much the same
general pattern as the earlier brochure (see notes provided in ID no. 604). The
later chapters are, however, additional and are devoted largely to a discussion
of the principles of sound land use and their application in farm practice.
Other matters dealt with include an assessment of the progress of the field
campaign as a whole since the promulgation of the Soil Conservation Act, a brief
outline of present and future farm policy in SA, and a concise account of inter-
African co-operation in the field of land use and soil conservation.

Notes : The objective of the study was to briefly describe the physical and
institutional inputs, as well as the environmental and human factors affecting
the operation of the scheme. The reserach methodology made use of a survey
questionnaire and an interview schedule, which brought out the responses which
were related to the aims and goals of the study. It is suggested from the
research findings that a quick evaluation of the impact of an irrigation scheme
should consider three kinds of responses, namely utilisation, efficiency of
production, and the effects of human development. A model in which the more
important indicators are listed, is further proposed. This thesis is obtainable

Notes : There were six purposes of the study, namely: 1. to describe the
history and institutional framework of the Ncora Irrigation Scheme; 2. to
describe the physical characteristics of the study; 3. to describe the technical
aspects that have an influence on production; 4. to describe the characteristics
of the farmers of the Qumanco administrative area; 5. to report on the attitudes
and perceptions of the farmers that may affect the expansion of the irrigation
scheme; and 6. to make recommendations on the development of Qumanco and
improvement of the Ncora Irrigation Scheme. A total of 21 irrigation farmers
were randomly selected for the study. Using a structured questionnaire, data
were collected from the sampled farmers. Descriptive statistics were used to
analysis the data. It was found that the existing management agency had
experience to develop the Qumanco area. Under dryland conditions a potential
maize yield of 3.5 tons per ha is possible. As 65% of respondents were over 45
years of age and 44 (40?)% over 60 years of age, large numbers of the present
land right holders lack the physical ability to do the hard work required for
irrigated farming. About 50% of the heads of households were women and one-
third of the respondents were either single, divorced or abandoned. More than
60% of the land right holders have education level less than 6 years at school.
Only half the respondents were positive about the effectiveness of their
traditional leaders. Major farming problems include harvesting, transportation
of crops, insect control, livestock management, weed control and theft. The
authors made a total of 47 recommendations. This report is obtainable from

Notes : The purpose of this article was to explore the perceptions on
development approaches of: 1. the management agency and consultant for the
irrigation scheme; 2. the advisors to the Department of Agriculture and Forestry
in Transkei from semi-government institutions who served on various committees
affecting the scheme; and 3. the officials of the Department of Agriculture and
Forestry who have been involved in some way with the development of the scheme.
Mors' criteria were used to describe the various development approaches. A
score sheet was designed and submitted to senior staff members of the management
agents, to consultants for the scheme, to senior departmental staff, as well as
to advisors to the Department of Agriculture and Forestry from semi-government
and other institutions, who were closely associated with the development of the
scheme. A total of 31 score sheets were distributed. The study revealed that
the consultants' development plan was based on a commercialisation approach but
that, in the implementation, a top-down approach was used, possibly because of
farmer reaction and/or pressure from the consultants' employers. It was found
that policy-makers had a different perception of the rationale for developing
the scheme, the role of expatriates, the emphasis of development at the scheme
and the goals pursued. About half of the policy-makers agreed that, in future,
the farmers should have a greater say in the development of the scheme. In
short, most of the respondents recommended more of a participatory approach to
development activities. The authors recommended the development of a model that
determines farmer needs and perceptions before a development activity takes
place. This article is obtainable from the Ncora Irrigation Scheme. See ref.

Abstract : This study, which was the first attempt to evaluate the effects of
the Ncora project on participating farmers, showed that the management was top-
down with decisions and most farming operations being carried out by the
managment agency. Consequently knowledge and management standards were
considerably below optimum. Although the majority of commercial farmers were
literate, this applied to only about 40 per cent of the other participants.
Except for the commercial farmers, most of the participants were women, and
labour shortages were experienced by two in five respondents. Scheme
participants have benefited in household mobility, health, intake of proteins
and vegetables, nutrition and income derived from farming. The unit sizes were
acceptable to most participants and the majority still preferred traditional
technology. Leadership in the project was weak and there was little empowerment
of the local community or contact with sources on information. Suggestions are
made for further investments in human capital through extension training,
literacy and institutional development.

Abstract : Eight sets of sequential aerial photographs taken between 1944 and
1992 were used to assess vegetation and erosion changes on the northern slopes
of Table Mountain, Cape Town, SA. A vector-based Geographic Information System
facilitated the generation of maps and statistical analysis of spatial data.
The results show that over this 48 year period, the vegetation class shrubland
without trees increased from 36% to 73% of the total area. By contrast, closed
and open canopy plantations of alien trees decreased from 13% to 4%
respectively. The time-series of erosion maps displayed a high degree of
variability but revealed that certain areas of the mountain slopes are prone to
accelerated soil erosion. Nonparametric statistical methods were used to
ascertain whether certain erosion features have a predictive relationship with
particular vegetation cover classes.

Notes : The purpose of the study was to gather data on unemployment among blacks
living in the rural parts of the former Ciskei. In the process general economic
information was also obtained. The investigation was conducted with five highly
structured questionnaires and an interview format. A team of four black Xhosa
speakers was used as interviewers. A sample of 283 households was interviewed.
A two-stage stratification method was used to select the villages. The
investigation reported on the demographic structure of the selected villages,
educational qualifications of the populations, permanent and resident migrants,
the economic structure of the populations including employment levels and
patterns, subsistence agriculture and welfare conditions. The unemployment rate
was below average but was found to be comparable to those found in urban areas.
Migrant labour was central to the Ciskei economy. 60% of the work force were
migrants. The average wage of a former Ciskeian labourer was less than the
metropolitan wage but higher than the earnings in small towns. In 50% of the
sampled villages, subsistence agriculture was irrelevant since land was not
readily available. The economy of the former rural Ciskei was therefore to a
large extent an urban economy. This paper can be found at the Cory Library,
Rhodes University, Grahamstown. See ref. I.D. no: 2339.

Notes : Vegetation surveys (basal cover) carried out over the period 1949 to
1955 in experimental camps, have shown that significant increases and decreases
in the shrub and grass components of the vegetation had taken place practically
irrespective of the treatment supplied. The wheel-point method was used in the
vegetation surveys. Treatments were rotational grazing, continuous grazing,
protection from grazing and grazing during specific seasons. Merino sheep were
used in the grazing treatments. The vegetation of the camps surveyed is broadly
representative of the gradually sloping basal pediments (apron veld) and dry
flats of the Eastern Mixed Karoo. This vegetation is primarily composed of
grass and shrubs - known as karoo bushes. Of the grasses the Eragrostis,
Aristida, Cynodon and Tragus are the more abundant. Of shrubs and genera
Pentzia, Pteronia, Chrysocoma and Eriocephalus are the more abundant. The shrub
and grass components are largely differentially inflluenced by seasonal
rainfall. The grasses are primarily stimulated and favoured by rains falling
during the period September to February, whereas shrubs are invigorated by rains
falling mainly during March to August and September. The species per vegetation
