four areas which were appraised, were referred to in
the study as i. Trans white Volta Plains Frontier
ii. The White Volta Floodplain frontier, iii. The
Nabogo - Nasia Frontier, iv. Transition into occupa
tion (fig. 2 ). Inter censal nonulation trends
(CBS, 1970, 1984) were matched with the FCC interpre
tative elements of those land cover classes described
inthe ohoto kevs. It was to serve as the basis for
describinq land occupation of the four areas that
were distinquished. Frcm the analysis a map of
settlements, associated land uses and population
chanqes between 1970 and 1984 was prepared (fig 3) .
Brief summaries of the main characteristics of each
of the areas distinguished were given:
I. the trans white volta plains frontier
The area has a distinctive character of general
emptiness and remoteness. These could be discerned
with the FCC’s information. There is virtual absence
of settlement and cultivation (plate, fig 3). As it
was indicated by the census data, some localities
suffered population decrease of up to 20% while
others increased by the same macniture. This would
require further landuse and demographic study. The
inacesibility situation, or the problem of remoteness
of the area was partly defined with the existing
1:50,000 topographical maps and with evidence
collected from the recce aerial fliqht over the
area. The only access route in the area was 'found
to be a dry season track which connects Navrongo in
the north. There is no bridge over the White Volta
sothe area is cut off from the eastern part where
is the only reqional road.
As reported by the Onchocerciasis Control Project,
(1973), the area was a hyperendemic zone with a blind
ness rate of over 70% amona the resident copulation.
This problem has been fairlv eliminated (OCP/WHO,
1984). Agricultural growth as a follaw-uo however
awaits, amonq other things, improvement of access
road and water supply. The soils range over upland
types ofqravelly coarse and fine sandy clay loam
occurina on rolling to hilly topography; sandstone,
rocky and iron pan soils occurinq on undulating land;
non-gravelly, coarse and fine sandy clav loams in the
upland of very gently undulating terrain; gravelly;
coarse and fine sandy loams and clay loams in the
shallow depressions and valleys. The lowland soils
have been assessed to be fairly good for both mecha
nized and hand cultivation (Obeng, 1975)
II. the white volta flood plains Frontier
The seasonal swamps stood out as dark, darkgreen and
bluish green in the FCC. These '»ere delineated and
cross checked with stereoscopic observation of the
existing aerial photographs. Those areas with consi
derable depth of water '.«ere shewn in the mappinq as
topographical information not onlv Far their useful
ness as natural reservoirs but also Far their possi
ble fishery potential. The depressions have soils
also suitable for rice cultivation. (Obenq 1975)
It is similar to the Trans White Volta in terms of
accessibility, ceoplinq and effective land occupation
In the imagery the general emptiness could be discer
ned, but local cultivation in the floodplains as it
was evidenced during the recce flight, had
increased since the imagery date. This expansion
has not been accompanied by settlement growth. It
has been on the basis of mechanized land rotation
operated mainly on capitalistic, absentee farming
system financed by local and urban based enterore-
neures with access to credits and other facilities.
The fishery potential of the White Volta has been
also assessed and found to be farily hiah (Norrip,
1983).
Drainaqe appears to be a major limitation to effect
ive utilization of the soils of the area, but even
when that is overcome, the associated water develo
pment would have to recognize disease effects on the
contact population (Hunter, Rey and Scott, 1980)
III. the nabogo - nasia frontier
It has a distinctive set of problems associated with
rapid landalienation for relatively fairlv larqe
scale rice cultivation in the floodplains and the
associatedvalleys (fig 5). Population increase in
the localities has been as low as 3% in sane and
as phenomenal as 200% in others. Land acquisition
for both traditional and modem mechanized, farming
has accordingly been intense and so have been frict
ions amonq the land users. It is one of the areas
where rice farming has been characterized with
incindiarism. Drought and stream sedimentation
have been significant. It is one of the areas of
rapid land occupancy and therefore calls for land
ownership and land use investigations to provide
the necessary data for rationalizing the situation
in order to promote sustainable kind of development.
IV. transition to permanent occupation
In the southern (Savelugu - Pong Tamale) landscape,
population increase in the various localities rang
ed between 10% and 262% with an average of about
190%. In the northern part (Wale Wale) landscape
the increase was between 69% and 96% with an avera
ge of 85%. In the imagery the dense dissemination
of patches of light tones gave indications of grow
ing intensitv of settlements and associated land
uses in 1975. Die generally gravelly soils of the
uplands (Adu, 1968) should require lonaer fallow
period but the population increase means that these
soils are increasingly ccming under pressure. The
practice of bush fallow system is narrowing down to
more or less permanent cultivation, which for the
soils of the area would require very careful manage
ment. Fuelwood Shortage is imminent (Norrip Tech..
Paper: Forestry Dev. 1983)
INTERPRETATION OF ASPECT OF THE RENEWABLEE
RiHJOURCES
Some key renewable resources were appraised in view
of possibilities for their implications in inter-
grated development of the area. The interpretation
identified these as (i) seasonal water bodies
(ii) riparian woodlands, and (iii) forage produc
tion of the shrub and tree savannah vegetation.
the seasonal water bodies
These constitute part of the surface water systems
of the Volta Basin, not only known for their disea
se effects on the contact population, as has been
evidenced in the prevalence of oncho but also the
fauna in them. Daget (1960) Roman (1979) have
identified a total of over 100 species fresh water
fauna inthe surface waters of the Volta Basin.
Exploitation of the fishery resources is, similar
to the v/ater level, seasonal, and could complement
farming activities very well since harvest of the
fisher'/ stock is mainly in the drv season when fishes
are confined to a few places with permanent water -
the channels of permanent streams, small lakes,
isolated pools i n the stream beds, residual oonds and
swamps in the floodplains.
The discussions of Lowe -Mcconnel (1975) and
Welcomme (1975) regarding the fisherv ecology and its
relationships to floodplains has relevance to the
fisherv manarrement of the studv area too. According
to them, during the rains the stream water becomes
heavily sedimented with nutrient salts from animal
dung and residues of overland waste disposal, agro
chemicals, decaving vegetation and from ashes of
