Effect of expanding sugar-cane farming on community woodfuel collecting areas, Masindi, Uganda
Développement des fermes commerciales et impact sur les
zones de collecte de bois de feu. Etude de cas du développement de
la canne & sucre dans le district de Masindi, Ouganda
Cet article montre que les populations proches des zones de
production de canne à sucre sont contraintes d'abandonner leurs
zones traditionnelles de collecte de bois de feu et rechercher de
nouveaux endroits. Afin d'atténuer ces problèmes, l'auteur
recommande des plantations à forte croissance destinées à la
production de bois de feu et servant de zones tampon entre villages
et forêts. L'auteur suggère la mise en place de petites aires
plantées en eucalyptus dans les régions impropres à la culture de
la canne à sucre. |
In most developing countries, dependence on biomass fuel as a
source of energy is very high, especially in rural areas; Uganda is
no exception. Over 87% of the population in Uganda live in rural
areas (1) and are reliant for nearly all their energy needs on
biomass (2). The availability of biomass fuel depends largely on
how land is being utilized. Land use changes are therefore a
crucial factor in determining the availability of fuel-wood at
household level. Commercial agriculture expansion has a large
impact on the locations from which local people collect their
woodfuel.
Over the last couple of years dramatic changes in land use have
occurred in rural areas in Uganda. In 1972, the dictator Idi Amin
forced the Asians to leave Uganda at short notice, leaving behind
all their possessions. Particularly in rural areas, large estates
were left fallow and, to some extent, were occupied by the local
population. The current Museveni regime welcomes ousted Asians to
reclaim their land.
Two sub-counties of the Masindi district were regions of severe
fighting in the 1970s. Besides the land left behind by ousted
Asians, the state-owned Kinyara sugar estate was abandoned. Large
areas were left unattended and were also a major source of woodfuel
for the local population.
With the return of peace in Uganda, a start was made to reactivate
the Kinyara sugar estate. At present, the estate is managed by an
international consortium, Kinyara Sugar Works, which reclaimed the
land and planted sugar-cane. Besides the Kinyara-owned land (the
so-called nucleus estate), the factory has now started to work with
out-growers. Outgrowers are local farmers growing sugar-cane on
their land aided by the estate, which clears bushes and trees from
the land, ploughs it, plants young cane and harvests the yield.
Farmers assisted in this way live within a 10 km radius of the
nucleus sugar estate. Recently the area in which Kinyara has
facilitated outgrowers was extended to a 15 km radius. An increase
to 20 km can be expected in the near future (3).

[end]Responses of the local population
The area under study lies between the protected Budongo Forest
Reserve and the current sugar estate. Villages in this area can be
grouped into three different groups:
- the area next to the sugar-cane fields
- the area adjacent to the protected forest
- the area in between areas 1 and 2.
From each region, one village was selected in which household
interviews were conducted to investigate the current and past
situation regarding the source of biomass energy used. The villages
of Kabango, Nyabyeya and Nyantonzi were selected respectively.
Table 1 gives an overview of the results of the household interview
conducted in July 1998.
Table 1 Percentage of total number of respondents collecting
woodfuel from certain land uses now and in the past
| Region | Village | Year | Natural woodlands | Private farms | Private fallow land | Protected riverine forest | Sugar-cane cleared area | Average distance |
| 1 | Kabango | 1998 | 12 | 46 | 19 | 19 | 12 | 1.5 |
| | 1960 | 46 | 31 | 23 | 0 | - | 1.0 |
| 2 | Nyabyeya | 1998 | 4 | 0 | 15 | 89 | 0 | 1.1 |
| | 1960 | 41 | 4 | 0 | 30 | - | 0.6 |
| 3 | Nyantonzi | 1998 | 48 | 48 | 0 | 44 | 0 | 1.9 |
| | 1960 | 56 | 36 | 16 | 4 | - | 1.6 |
The village in the first region (Kabango) showed very clear
evidence of wood scarcity. As shown in Table 1, villagers used to
collect their fuel wood mainly from natural woodlands, which are
now converted into sugar-cane growing areas. At present, nearly 50%
of the households in Region 1 buy charcoal from traders who use
wood from land being cleared for sugar-cane growing. This source is
temporary and will cease to exist when all the potential sugar-cane
growing area has been cleared.
The village near to the protected forest (Nyabyeya) shows a shift
in collecting fuel from natural woodlands to protected forest
resources. Analysis indicates that the original fuel wood
collecting area of woodland is now in used for subsistence farming,
leaving the protected forest as the only nearby source. Access to
this resource is still permitted, but government policies might
alter this situation.
The third village (Nyantonzi), in the intermediate area, also shows
a much higher dependence on the protected forest reserve but,
unexpectedly, no reliance on the cleared sugar-cane area.

[end]Land use change analysis
Land cover maps were produced for the situation in I960 and in
1998. The I960 land use map (Figure 1) was based on an existing map
of I960. Classification of land use in the table was based on any
information provided on the map. Although incomplete, it clearly
shows the sugar-cane growing area as well as forested areas.
Figure 1: Land use in 1960

The 1998 land-use map (Figure 2) was based on the available land
use map of 1996, as produced by the National Biomass Study, updated
by mapping new sugar-cane growing areas with a handheld GPS
satellite receiver. Newly cleared wooded areas were mapped in the
same way. The results are shown in Table 2. It can be seen that the
land lost in the woodland and grassland categories nearly equal the
increase in commercial and subsistence farming.
Figure 2: Land use in 1998

An intermediate map for the year 1987 was also produced by
estimates based on the answers received from the interviews. The
purpose of this map is to determine the expansion of sugar-cane
growing fields (see figure 3). The three maps together clearly show
that the major land use changes took place in the last decade only.

The data collected in this study show clear evidence of a rapid
expansion of the sugar-cane growing area. As a result, local people
near the sugar-cane estates have had to go to different areas from
those they were using previously to collect their wood. In the
current situation, local woodfuel demand can be met by using wood
from land cleared in preparation for sugar-cane growing. This
supply is not sustain-able. In order to facilitate local wood
energy planning, more research will be needed to quantify the
demand of wood by the local people and the available biomass in the
area.

Possible interventions may be triggered by increasing scarcity of
woodfuels and by the re-activation of improved stoves programmes in
the area. The Nyabyeya Forestry College in Masindi might play a
pivotal role in this by integrating the promotion and utilization
of their pekope stove as part of their educational programme.
To solve future fuelwood problems and to conserve the protected
Budongo forest it is recommended that fuel-wood plantations are
established as a buffer between the forest and villages. Indigenous
fast growing species which can be coppiced, as already planted by
farmers around their homesteads, might be planted in participatory
forest management projects on the degraded areas around Budongo
forest.
A rapidly accessible new source of wood fuel for local people could
be formed by the small patches of eucalyptus that are planted by
Kinyara on their estate in areas not suitable for sugar-cane.
Originally these trees were planted to discourage illegal homes
being built on the land. Using the trees as woodfuel will give them
a more positive function.
Furthermore, government policies have to be formulated that compel
companies involved in wood depletion to contribute directly to the
replenishment of wood resources.
