Issues relating to desertification in the drylands of Niger
The issues
Causes
Drought
Climatic variations
Low soil water holding capacity
Inherent low soil fertility/declining soil
fertility
Low soil organic matter levels of the drylands
Cultivation of marginal lands
Population pressure in reduced/eliminated fallow
period
Land tenure problems
Inadequate feed and fodder for livestock
Livestock population in excess of the carrying
capacity of the rangelands
Increasing migration of livestock from neighboring
countries Chad, Nigeria and Burkina Farso
Encroachment of crop cultivation into designated
livestock routes and grazing reserves
Depletion of water resources (surface
and groundwater)
Damming of rivers, thus depriving downstream users
of access to water
Increasing human and livestock population
Increasing demand caused by increasing
urbanization and industrialization
Low forest cover
Excessive wood extraction for fuel construction
(lumber)
Bush burning
Uncontrolled land clearing for agricultural purposes
Legislative framework
Low level of education and public awareness
Conflicting policies and regulations
Poor enforcement mechanism
Inadequate capacity
Uncoordinated research efforts on problems relating
to drought and desertification
Obsolete research and meteorological equipment
Low and erratic funding for desertification control
projects
Coordination of activities
Sectoral approach to project planning formulation
and implementation
Insufficient involvement of all stakeholders,
particularly resource-users, in project planning,
formulation and implementation
About 2,500 km 2 , are being lost each year in Niger through desertification. This
is equivalent to the area of Luxembourg. Studies carried out in the 1980 estimated
the natural forestry potential at 16 Mha with a very low productivity of between
0.1 and 1.5 m 3 /ha/year. The forestry structures exploited for wood-energy (about 4
Mha) provide around 90 % of the needs, that is to say three million tons per year. The
“wood-energy assessment” established in the late 1990s indicated that some regions
of the country are already in deficit. The problem of wood supply is particularly
