studies over the last 30 - 40 years in a wide variety of fields including
palaeobotany, archaeology, ecology and biogeography. (2) The classical view is
that many of SA's grasslands have arisen as a result of the extensive removal of
forest trees by Bantu and European farmers during the last 600 years. The view
in this paper is that the grassland biome as it is presently mapped has been in
existence for at least 1000 years, but probably for much longer. (3) This
makes it necessary to re-examine the determinants of the grassland biome as a
whole, and a number of suggestions are made, including climatic and edaphic
conditions, and naturally occurring and anthropogenic fires initiated by Stone
Age people before the subcontinent was settled by Iron Age people.

Notes : (1) A novel modelling approach has been used to synthesize, test and
improve current understanding at the subcontinental scale of the location of
boundaries between the grassland biome and those with woody elements (forest,
fynbos, nama-karoo and savanna) in SA, and also at the landscape scale of the
determinants of the distribution of wooded patches of different affinity within
the grassland biome itself. At the landscape scale the determinants of the
distribution of forest patches in the grassland biome are emphasized. (2) The
development of predictive and therefore testable models has been useful in
identifying weaknesses in current wisdom, has illustrated the importance of
climate in determining the distribution of vegetation at a subcontinental
(biome-wide) scale, and of edaphic conditions and disturbance regimes at a
landscape scale. (3) The hierarchical nature of the modelling approach used
makes it useful in modelling the determinants of vegetation distribution at
different scales of resolution, a prerequisite for predicting the consequences
of global changes in climate and disturbance regimes for vegetation change.

Notes : The grassland biome in SA can be distinguished from neighbouring biomes
on the basis of three climatic indices which are considered to be biologically
meaningful. The indices are 'days of growth opportunity' based on soil water
availability and calculated using a water budget model, the mean temperature on
days when sufficient water is available for plant growth, and the mean
temperature on days too dry for growth to occur. The difference between the
growth and no-growth temperatures provides an indication of the degree of
rainfall seasonality. These indices have also been used successfully to
differentiate the five other biomes in SA (forest, fynbos, nama-karoo, savanna
and succulent karroo) in a 'biome model' presented as a decision-tree. This
model provides a simple method of predicting possible vegetation reponses to
climatic change. The possible long-term response to a scenario of climatic
change, (a 2oC increase in termperature and a 15% decrease in rainfall), is
illustrated as an example. Such an approach to modelling the impact of climate
change has several advantages, including simplicity, appropriateness of scale
and detail to the predictions of current climate models, identification of
regions and processes that may require more intensive study and identificaton of
the kind of information that will be required if scenarios of climatic change
are to be translated into vegetation response. The model fails, however, to
identify rates or pathways of change, or the species involved. This approach
will therefore have to be complemented by more detailed dynamic models.

alternate paradigms and implications for development. Journal of Range

Keywords : POLICY
Abstract : African pastoral ecosystems have been studied with the assumption
that these ecosystems are potentially stable (equilibrial) systems which become
destablized by overstocking and overgrazing. Development policy in these
regions has focused on internal alterations of system structure, with the goals
of restoring equilibrium and increasing productivity. Nine years of ecosystem-
level research in northern Kenya presents a view of pastoral ecosystems that are
non-equilibrial but persistent, with system dynamics affected more by abiotic
than biotic controls. Development practices that fail to recognize these
dynamics may result in increased deprivation and failure. Pastoral ecosystems
may be better supported by development policies that build on and facilitate the
traditional pastoral strategies rather than constrain them.

Notes : The purpose of this article is to review past and present agricultural
development initiatives in Transkei, and to examine the reasons why these
initiatives have, on the whole, proved to be a failure. Information for this
study was obtained through discussions with individuals who are directly or
indirectly involved in agricultural development initiatives; from various
reports and from the author's experience as general manager (agricultural
services), Transkei Agricultural Corporation. The study showed that subdivision
of available arable land into non-viable units and over-exploitation of communal
grazing areas hindered agriculture from contributing to rural livelihoods.
Incentives from increased agricultural production were small. The technology
provided was based upon the needs of the commercial sector, which has a very
different set of constraints and resources. Other constraints include the lack
of an effective extension service, credit facilities, a distribution network for
agricultural inputs, facilities for making surplus produce and facilities for
training. Strategies which can make agriculture in the future contribute
towards improved rural livelihoods include: 1. mechanisation services to small
farmers by private enterprises; 2. government and parastatals; 3. improved soil
conservation measures; 4. involvement of local people in schemes; 5. support
from chiefs, political leaders and tribal authorities; 6. effective extension
efforts and more training for extension workers; 7. revitalisation of the co-
operative movement to enable inputs reach the rural areas; and 8. close co-
ordination between the co-operative and extension efforts. This article can be

Notes : The purpose of the paper was to outline the agricultural development
initiatives of the various governments of the Transkei prior to independence and
up to the present time. Field visits and interviews were used for the study.
The findings include the fact that the agricultural economy of Transkei was
characterised by: 1. 450 000 rural households (90% of the population) of which
60% now have access to land; 2. 500 000 migrant workers with increasing
unemployment; 3. small arable allotments averaging less than 2 ha, together with
individual homesteads and access to communal grazing; 4. very low yields with
maize yields averaging less than 0.5t/ha; 5. very low livestock productivity; 6.
extremely serious resource degradation and some of the worst soil erosion
certainly in Southern Africa; 7. overgrazed veld and deteriorating water
resources; 8. an inability by most rural households to feed themselves let alone
provide any surplus for sale, hence the dependence on "migrant" labour and
remittances for survival; and 9. less than 10% of the food consumed is produced
in the former Ciskei. This paper can be found at the offices of the Border
Rural Committee, East London. See also ID ref. no. 2339.

Notes : The overall objectives of this study are: to provide a synoptic view of
the environmental conditions; to assess the present degree of degradation; to
develop methods of predicting future changes; to monitor long term changes and
trends; and to provide a quantified base for evaluation. The chosen methods
should be locally appropriate to skills, finance and technology levels, robust,
sustainable and, wherever possible, the data should be existing. The specific
objectives of the monitoring programme based on the above overall objectives
were stated to be: to provide an inventory of the available relevant resources
in the SADC region; to monitor chanes in indirect and direct indices reflecting
land degradation, soil erosion and desertification; to monitor changes in land
use, management, soil quality and vegetative biomass quality and quantitiy; to
measure classify and predict wind and water-related soil losses; and to evaluate
the above informaiton sources in order to identify environmental trends within
the region. The purpose of these guidelines is to assist in the development of
an organized and co-ordinated system for monitoring land degradation, soil
erosion and desertification at national and regional levels in the SADC Region,
which is sensitive to the need to fully utilise existing data, while not
excluding the possibility of develping additional technologies within the means
of the countries in the region.

Notes : The purpose of the study was to identify the role of extension officers
as the principal actors of the extension services, and how communication could
assist them to be better facilitators, motivators, trainers and sources of
accurate and appropriate technical advice. The study used personal interviews,
group interviews and a literature review for data collection. The study found
that better communication would assist agricultural extension services to
improve their image, credibility and role in farmers' view. Communication would
also improve their ability to better identify farmers' needs, priorities and
indigenous knowledge. Further, improved communication increases their capacity
for effective participation, empowerment and learning through employing
participatory methods. The study also found that better communication in
extension services could improve the quality of liaison between rural
communities, extension officers and other administrative structures which could
help solve farmers' identified needs such as credit facilities, potential
markets for their produce, financial programmes and better business skills.

Notes : The set of three preliminary reports represent about ten months of
research. Although substantial work has been done, the project has not yet been
completed and the work is continuing. The main themes requiring further work
(suggestions will be sought from participants at the workshop) will be on the
following: (a) The economic study analysed the land use options of communal and
commercial farming because these are the current land use practices and data is
fairly readily available. The option of utilising the land for one or other
wildlife use have only tentatively been investigated although the study on
Manyeleti provides some information. The wildlife option is a very real one for
these and also many other communities. These areas are all "Big Five" terrain
and border on reserves that retain these immensely sought after animals in
international tourism. It is foreseen that pressure will mount for the
utilisation of communal areas adjacent to "Big Five" reserves for tourism. This
presents a major opportunity for these communities to improve their lifestyles.
However, many different models for the implementation of such developments are
possible with maybe different social and economic implications for the
communities. Further work will analyse these different models. This would lead
to better policy making and implementaiton of projects in socially acceptable
ways. (b) The completed work already made some progress on studying the
ecological functioning of communal grazing systems. The main report points out
that this is a very underresearched topic but one on which much uninformed
opinion exists. The general perception is that these areas are severely
overstocked and about to become wastelands. In many areas this did not happen
and one season of good rain usually restores the veld to good condition. Better
understanding of the functioning of these systems will save a lot of resources
currently wasted on extension work based on incomplete if not incorrect
understanding. With some additional fieldwork and further analysis of already
collected data a more significant contribution could be made to an understanding
of this important activity on which livelihood a large number of rural people
still depends. (c) Initial scrutiny of the results presented in the social and
economic documents revealed very large variation around the averages of the
various observations made. This seems to be indicative of definite socio-
economic strata in the communities studied. There seems to be a small "well-
off" section and also a large poor to very poor section of the populace.
Presentation of averages tends to hide these very important distinctions.
Existing data will be further analysed to bring these distinctions clearer into
focus. Some additional survey work on the Makripene, Million and Thorndale
communities (which seem to be poorer than Seville and Uthla) may also be
undertaken. (d) Integration of the ecological, economic and social aspects of
the study. The project team feels that the three reports are still too much
three loose entities. The ten months of the project was sufficient for the base
work and only some integration to be done. Further work will attempt fuller
integration of results and of interpretations made.

Notes : This study was commissioned by the Development Bank of Southern Africa
(DBSA). The project forms a component of a project initiated by the DBSA
entitled: The economic, social and ecological implications of alternative forms
of rural land use in Gazankulu. This assignment falls within the Rural and
Agricultural Policy Program of the DBSA. The study area is located in the
Seville and Uthla tribal areas in the Mhala district of the former Gazankulu,
presently the Northern Province. The aim of the study was to determine the
extent and ecological implications of different management practices.
Understanding of the effect of high stocking rates on communal grazing systems
will improve the quality of management prescriptions for these areas. In
general, the results of the study aims to contribute to the understanding of
sustainable land use in poverty stricken rural areas and will serve as a guide
to the planning and financing of rural development projects.

Notes : The purpose was to analyse the existing characteristics of the area and
to draw conclusions. A large proportion of information was found in existing
reports. The investigation team further collected information by interacting
with some residents of the area. It was found that people in the area heavily
depend on pensions, external wages and subsistence farming. There is also high
unemployment. Little assistance in training of agricultural support has
resulted in the farms not being aware of better farming methods, which could
increase production efficiency and income. The authors felt that the farms, if
properly managed, could support more people and provide more agricultural
produce. Proper farm management can be achieved if issues on tenure,
infrastructure, farming skills, high unemployment and low economic activity,
conflict over access to agricultural land, under-utilised land with farming
potential are addressed and resolved. This report is obtainable from the BRC

Notes : The purpose was to contribute towards the knowledge concerning the
relative developmental strengths and weaknesses of Region D, as reflected in its
potential, needs and constraints, and to serve as input towards the formulation
of strategic development proposals for the regions. Interviews, a literature
search and qualitative data collection was used. The largest sections in Region
D's economy are community and social services (with 24,6% of GDP), and
manufacturing (with 23,3%). Although the relative importance of manufacturing
sector has decreased sharply, the economy of the region is still rather
concentrated and is therefore relatively vulnerable. Consequently, concern
emerged that the community and social services sector was the most important
sector in the economy, with agriculture second and construction third. In
diminishing order of importance, the other sectors appear as follows: commerce,
manufacturing, transport, finance and business services, and electricity. This
would seem to indicate structural problems in the economy of Region D as
community and social services are mainly a governmental supported sector. This

Notes : The author concludes that both the individual and authorities must take
some responsibility for the preservation of natural resources. This
responsibility and accountability cannot be delegated. The extent to which
environmental responsibility is developed, depends largely on the degree to
which energy is available in a system. The individual and authorities are
accountable to each other in respect of the environment in which they live. In
