Three new Ramsar sites in the Niger River Basin

Niger names three important Ramsar sites in the Niger basin
The government
of Niger, which has been taking vigorous steps in recent years, with the energetic
assistance of WWF
International's
Living Waters Programme, to designate for the Ramsar List a number of extremely
valuable wetland areas along the Niger River and in the Lake Chad Basin, has
recently listed three new sites, totaling over three quarters of a million hectares
along the Niger and two of its former tributary valleys from the north. Ramsar's
Abou Bamba, Senior Advisor for Africa, was able to present Niger's president,
Mamadou Tandja, with "site diplomas"
for the three new sites at President Jacques Chirac's meeting in Paris on 26-27
April 2004, "Partenariat international pour le Bassin du Niger: vision
partagée, de la stratégie vers un plan d'action", and now
that the site datasheets have been thoroughly gone over by the Africa team in
the Secretariat, the new RSs can be added to the List of Wetlands of International
Importance. The three sites are Dallol Bosso (376,162 hectares), Dallol Maouri
(318,966 ha), and Zone humide du moyen Niger II (65,850 ha) in the Niger floodplain.
Dallol
Bosso. 26/04/04;
Dosso; 376,162 ha; 13°57'N 002°98'E. A system of seasonal watercourses
and permanent pools in the old north-south valley of a long inactive branch
of the river Niger, associated with a long 775km depression running southward
from Mali. Sandy soils with a near-surface aquifer contribute to the agricultural
importance of the area and to the only viable West African population of the
giraffe Giraffa camelopardalis. The site also supports numerous fish
species at different stages of their life cycles, and certain species migrate
towards the Niger during the winter season, enriching the biodiversity there.
Chief human uses of the area include irrigation agriculture, livestock, forestry,
fishing, and the extraction of the salt-like natron. The effects of desertification
in the region, including uncertain rains, sand encroachment, and inadequate
groundwater recharge, give cause for concern, and overgrazing and soil impoverishment
through overcultivation are seen as potential threats. The area is adjacent
to Parc National du W and part of the UNESCO Biosphere Reserve of that name.
Ramsar site no. 1382.
Dallol Maouri. 26/04/04; Gaya; 318,966 ha; 12°04'N 003°30'E. A former north-south tributary of the Niger along the frontier with Nigeria in the southwest, now a complex of permanent saline/alkaline pools and seasonal streams and creeks with an exceptional complex of vegetation including the Palmyra palm Borassus aethiopum and African doum palm Hyphaene thebaïca. Some nine ethnic groups contribute to the human population, and rainy-season agriculture and market gardens, salt extraction, fishing, forestry, and grazing are the principal means of livelihood. A high sustainable tourism potential is seen, and a local research programme, financed by Switzerland, is studying potential development in sustainable livelihoods. As elsewhere in the region, the effects of desertification comprise the most worrying threats to the site. Ramsar site no. 1381.
Zone
humide du moyen Niger II. 26/04/04; Dosso; 65,850 ha; 12°21'N
002°54'E. A 25km stretch of the river Niger along the border with Benin
in the southwest of the country, with associated floodplains and pools. The
area is extremely important for the presence of hippo grass echinochloa stagnina,
a quality forage plant, and the grass anthephora nigritana which provides
habitat for thousands of waterbirds as well as pasturage. Threatened species
include the white-tailed mongoose, the pale fox vulpes pallida, and the
African manatee Trichechus senegalensis, and the permanent pools provide
refuge for several fish species that have disappeared elsewhere along the river.
The hydrological regime is characterized by a period of flooding of 4-5 months,
beginning in August with local torrential rains and again in November with floods
coming down from upstream. The rich alluvual soils provide agricultural and
pastoral livelihoods, but unwise practices, as well as invasions of the cattail
typha australis, present potential threats. The land is largely state-owned
but the population has long-standing usage rights. Ramsar site no. 1383.
