Forest products and services
The products and services derived from forests are
diverse and benefit people at the local, national,
regional and global levels. Communities living near
forests rely on the resources for most of their consumption
goods, shelter and even clothing.
Woodlands provide wild foods as a dietary supplement
for communities, and they provide a habitat
for activities such as beekeeping and hunting.
Woodlands and forests also provide timber, poles
and other construction products, materials for craftmaking,
tool handles and household utensils.
Mopane, for example, is greatly desired as a strong
termite-resistant construction wood and for firewood,
while species such as Zambezi teak, Mukwa
(Kiaat) have been heavily exploited for furniture,
parquet blocks, railway sleepers, etc. Other important
timber species are Muwanga, Pod mahogany,
African ebony, Panga panga and Leadwood.
Forests and woodlands are the source of many
non-wood products, including extractives such as
bark, dyes, fibres, gums, incense, latex, oils, resins,
shellac, tanning compounds and waxes.
Forest logging and timber sales contribute significantly
to Gross Domestic Product (GDP) of basin
countries, thus boosting their economies and providing
employment to thousands of people. In
Tanzania, forests contribute four percent of GDP.
- Climate regulation – large blocks of forests have great influence
on the climate. They act as buffers and regulate the climate over
a large part of the land surface.
- Gas regulation – ecosystems also play a crucial role as carbon
dioxide sinks and in the production of oxygen. Tropical forests
contain up to 100 times more carbon dioxide in their vegetation
and soils than croplands and pastures. Some of this carbon
is absorbed from the polluted environment in the basin.
- Watershed protection – forests help stabilise the land by
reducing soil erosion. This allows for more water, which
would otherwise be lost where there are no forests, to be
captured. Trees protect soil against erosion, runoff and compaction.
Areas protected by forests also act as a source of
water for local communities.

Uses and values of forestry products
Forest resources have various uses and values in the
Basin, including ecological, cultural and socio-economic.
They ensure a regular supply of fresh water,
prevent flooding, protect crops from wind damage
and prevent soil erosion and siltation of riverbeds
downstream. Forests are also regarded as new land
for expansion of food production and settlements.
Forests provide the primary source of energy in
the Basin in the form of firewood and charcoal.
About 74 percent of total energy requirements of
the eight basin states comes from biomass.
Woodfuel makes up a larger share of energy
resources in all basin states with Namibia getting 91
percent of its energy needs from fuelwood, followed
by Malawi and Tanzania at 90 percent,
Botswana 73 percent, Zambia 62 percent and
Zimbabwe 57 percent. Other rural industries that
consume significant amounts of woodfuel include
brick manufacturing, charcoal burning, lime production,
fish-smoking, beer-brewing, and coffee,
tea and salt-drying.
The high costs of alternative energy sources such
as electricity in urban areas have translated into high
urban woodfuel demands, leading to severe forest
and woodland depletion in the peri-urban areas.
Forests are also useful for recreational and cultural
purposes. They meet the spiritual needs of the
indigenous people through specified tree species
and blocks of woodlands conserved by communities
for cultural reasons such as traditional rain-making
ceremonies.
