Uruzi rwa Hadejia

ni rumwe mu migezi ikomeye yo mu buraruko bushira ubuseruko bwa Nigeria, ruzwi cane mu karere ka Sahel kubera uruhara rwarwo mu bibaya vy’ibishanga (wetlands) no mu buzima bw’ibinyabuzima. Ni rumwe mu mashami y’uruzi rwa , narwo rujya mu sisitemu y’uruzi rwa Lake Chad

Izina: Uruzi rwa Hadejia

Igihugu: Nigeria

Uburebure: ~300 km (hafi, bivugwa bitandukanye)

Isoko (source): Amajyaruguru y’ubuseruko bwa Nigeria (Jigawa / Kano uplands)

Iherezo (mouth): Rwinjira mu migezi ya Komadugu–Yobe system

Sisitemu: Lake Chad Basin

Akarere runyuramwo: Kano, Jigawa, Yobe (inkengero)

Ubwoko: Uruzi rufitaniye isano n’ibishanga (wetland river system)

Aho ruva n’aho rugana

Uruzi rwa Hadejia ruvira mu misozi n’ibibaya biri mu ntara za Kano na Jigawa. Amazi y’imvura n’imigezi mito mito ni yo atuma rutangira.

Rugenda rumanuka mu bibaya vyagutse, rugaca mu ntara ya Jigawa, hanyuma rugakomeza rujya mu sisitemu y’imigezi ya Hadejia–Jama’are–Komadugu Yobe, igana ku kiyaga ca Chad (Lake Chad basin).

Uturere ruza ruracamwo

Uruzi rwa Hadejia ruca mu bice bikurikira:

Kano State (isoko ry’amazi)
Jigawa State (akarere kanini karwo)
Yobe State (inkengero za sisitemu yarwo)
Ibishanga n’ibibaya vya Sahel

Ibishanga vya Hadejia (Hadejia–Nguru Wetlands)

Kimwe mu bintu bizwi cane kuri uru ruzi ni ibishanga binini vyitwa:

Hadejia–Nguru Wetlands

Ibi bishanga ni ngirakamaro cane kuko:

bitanga aho ibikoko bibamwo
bifasha mu kugenzura imyuzure
bituma abanyagihugu babona amafi n’amazi

Akamaro k’Uruzi rwa Hadejia

1. Ubuhinzi

Uruzi rwa Hadejia rufasha cane mu buhinzi bwo mu buraruko bwa Nigeria:

guhinga umuceri (rice cultivation)
ibinyamisogwe
imboga mu bibaya vy’amazi

2. Uburovyi

Ibishanga vyarwo bituma habaho:

amafi menshi
uburovyi bw’abaturage benshi
isoko ry’ifunguro n’ubutunzi

3. Ibinyabuzima

Akarere k’uruzi kazwi kubera:

inyoni nyinshi ziva no mu mahanga (migratory birds)
ibikoko vyo mu bishanga
biodiversity ikomeye cane

4. Amazi n’ubuzima

Amazi y’uruzi akoreshwa mu:

kunywa
isuku
ubuhinzi bwo mu ngo

Ibibazo ruhura na vyo

Uruzi rwa Hadejia ruhura n’ibi bibazo:

kugabanuka kw’amazi kubera amapompage (irrigation)
ihindagurika ry’ibihe (climate change)
isenyuka ry’ibishanga
kugabanuka kw’inyoni n’amafi

Akamaro mu bidukikije

Uruzi rwa Hadejia rufise uruhara runini mu:

kugenzura imyuzure
kurinda ubutaka gusenyuka
gutuma ibinyabuzima bibaho neza mu karere ka Sahel

Umusozo

Uruzi rwa Hadejia ni rumwe mu migezi ifise akamaro kanini mu bibaya n’ibishanga vya Nigeria, cane cane mu karere ka Lake Chad Basin. Kurubungabunga ni ngombwa kugira ngo amafi, ibinyabuzima n’abantu bakomeze kuronka amazi n’ubuzima bwiza.
