Conflicts in l<strong>and</strong>-use, disparate political “Visions” for Namibia’s future, <strong>and</strong> low status <strong>and</strong><br />

capacity of both the Ministry of Environment <strong>and</strong> Tourism (MET) <strong>and</strong> the Directorate of<br />

Forestry (DoF) of the Ministry of Agriculture, Water <strong>and</strong> Forestry (MWF).<br />

The absence of adequate L<strong>and</strong> Use Planning (LUP) threatens biodiversity <strong>and</strong> conservation<br />

efforts throughout Namibia.<br />

The environment competes with people, livestock, mines, industry, <strong>and</strong> irrigation for Namibia’s<br />

scarce water resources. Human water dem<strong>and</strong> in the country is expected to increase by 230%<br />

between 2008 <strong>and</strong> 2030. The <strong>environmental</strong> implications on ecosystems <strong>and</strong> the hydrological<br />

cycle are not well considered <strong>and</strong> political decisions regarding water use are not always consistent<br />

with policy directives.<br />

While woodl<strong>and</strong>s are conserved to some degree inside protected areas, community forests, <strong>and</strong><br />

conservancies, the controls on wood harvesting, transportation, <strong>and</strong> selling of wood products is<br />

inadequate. As a result, trees are suffering increasing rates of deforestation. The biggest losses of<br />

natural woodl<strong>and</strong> have occurred from clearing of l<strong>and</strong> for crop cultivation, cutting of trees for<br />

firewood <strong>and</strong> construction, <strong>and</strong> the frequent burning of trees as a result of veld fires in the<br />

northeast. As people’s livelihoods become more threatened by increasing temperatures <strong>and</strong><br />

aridification (as predicted in the most recent climate change reports) rural poverty is likely to<br />

increase <strong>and</strong> with it, rates of deforestation <strong>and</strong> increasingly unsustainable l<strong>and</strong>-use practices <strong>and</strong><br />

the harvesting of indigenous forest products.<br />

The carrying capacity of an estimated 26 million hectares of rangel<strong>and</strong>s in central <strong>and</strong> eastern<br />

Namibia has been greatly reduced by bush encroachment – a major form of l<strong>and</strong> degradation.<br />

These dense thickets of thorny bush grow in response to the overstocking of cattle, a<br />

corresponding loss of perennial grasses <strong>and</strong> a reduction in the number of browsing ungulates.<br />

These human-induced <strong>threats</strong> are exacerbated by climatic conditions that favor the flowering,<br />

seeding, <strong>and</strong> germination of woody plants – especially during dry periods when water is more<br />

accessible to deep-rooted plants, rather than shallow-rooted grasses.<br />

Namibia is currently experiencing rapid growth in its charcoal industry. Unless adequately<br />

monitored, this potentially valuable industry (it can help to combat bush encroachment) is likely<br />

to result in the over-exploitation of many valuable tree species.<br />

Higher temperatures, lower rainfall <strong>and</strong> higher evaporation rates across Namibia are predicted<br />

with climate change. These cumulative impacts will result in increasing aridification across most<br />

of the country, lower primary production of rangel<strong>and</strong>s <strong>and</strong> reduced carrying capacity for<br />

wildlife.<br />

From a biodiversity perspective, the CC impacts on water availability are likely to be severe –<br />

especially in western Namibia where trees in ephemeral riverbeds act as linear oases that provide<br />

essential fodder <strong>and</strong> habitats to many species. The decline in surface water (small springs <strong>and</strong><br />

seeps) in the more arid areas will affect bird <strong>and</strong> game populations negatively. Reduced inflows<br />

into the Etosha Pan may impact on the natural springs around the southern parts of the pan <strong>and</strong><br />

on the breeding of some important species.<br />

<br />

In addition to the direct impacts of CC on biodiversity, global warming will further exacerbate<br />

poverty <strong>and</strong> household food amongst subsistence farmers – thus placing more pressure on the<br />

l<strong>and</strong> <strong>and</strong> its resources.<br />
