Noka ya Malagarasi

Noka ya Malagarasi ke noka e e mo bophirima jwa Tanzania, e elela mo Kgaolong ya Kigoma, le fa e le gore nngwe ya dinoka tsa yone e tswa kwa borwabotlhaba jwa Burundi. Noka eno gape e bopa molelwane wa bophirima wa Kgaolo ya Tabora, molelwane wa borwa wa Kgaolo ya Kagera le molelwane wa borwabophirima wa Kgaolo ya Geita. Ke noka ya bobedi e telele go gaisa kwa Tanzania morago ga Rufiji ⁇ Great Ruaha, mme e na le metsi a magolo go gaisa noka epe e e elelang mo Letsheng la Tanganyika. [1]Malagarasi-Muyovozi Wetlands ke lefelo la Ramsar. Ditso tsa lefelo leo di bitsa Malagarasi di re ke "noka ya meya e e bosula".

Dipopego tsa lefatshe

[fetola | Fetola Motswedi]

Malagarasi ke noka ya bobedi e telele go gaisa kwa Tanzania, ka dikilometara di le makgolo a mane le masome a supa le botlhano. [2][3]

Motswedi wa noka eno o gaufi le molelwane wa Tanzania le Burundi.[1] Dikilometara tsa ntlha tse masome a robabobedi (50 mi) tsa noka di dira molelwane wa boditšhabatšhaba magareng ga Tanzania le Burundi. Dinoka di le mmalwa tse di elelang go tswa kwa dithabeng tsa Burundi di tsena mo lobopong lwa yone lo lo kafa mojeng. Morago ga go kopana le Noka ya Lumpungu, Malagarasi e tsena mo Tanzania, e dira sediko e bo e tshologela kwa ntlheng ya botlhaba jwa Letsha la Tanganyika dikilometara di le masome a mane kwa borwa jwa Kigoma, gaufi le Ilagala. [4] Ke nngwe ya metswedi e megolo ya metsi e e tsenang mo letsheng leno. Noka ya Moyowosi ke yone e e tsenang mo go yone, mmogo le noka ya Nikongo;[5] dinoka tse dingwe di akaretsa Noka ya Ugalla, Noka ya Gombe, Noka ya Ruchugi, Noka ya Lumpungu,[6] le Noka ya Nguya. Ke noka e e nang le melatswana e e kwa tlase,[7]mme metsi a yone a na le mafelo a le mane a botshelo: mafelo a a ditlhatshana, melatswana ya dinoka, noka e e elelang e e nang le melatswana e se kae, le delta e kgolo e e nang le makala a mabedi.[8]

Go elela ga noka go farologana thata magareng ga modikologo wa ngwaga le ngwaga wa dipaka tse di metsi le tse di omileng, mme ka dinako tse dingwe go ka nna ga nna le merwalela kgotsa go fokotsega go nna molatswana o monnye; go elela gape go amiwa ke temothuo ya selegae le go rengwa ga dikgwa tse di oketsang selekanyo sa matlakala mo nokeng. [1] Kwa Mberagule, metsi a noka a lekanyeditswe go nna 6,9 dikhubikilometara ka ngwaga. [2] [1]Mo e ka nnang dikilometara di le masome a robabobedi go tswa mo molomong wa yone, noka e elela go kgabaganya mafelo a a nang le metsi a mantsi a Moyowosi, lefelo le le nang le "maru a magolo le mafelo a a nang le metsi a mantsi" le "marshy labyrinth". [9][10]E feta ka Dodoma Belt, lefelo la thutafatshe la Archaean le Proterozoic age Precambrian crystalline rocks.[1]

Kgaolo ya metsi

[fetola | Fetola Motswedi]

Ka kgaolo ya noka ya 130,000 square kilometres (50,000 sq mi), Malagarasi e na le metsi a magolo go gaisa dinoka tsotlhe tse di elelang mo Letsheng la Tanganyika. [1]Lefelo la metsi la Malagarasi le dira 30% ya lefelo la metsi a letsha la Tanganyika.[11]

Lefelo la metsi la Malagarasi le kgabagantswe kwa bokone ke letsha la Victoria, kwa botlhaba ke lekadiba le le tswaletsweng la Southern Eastern Rift, kwa borwa ke lekadiba le le tswaletsweng la Letsha la Rukwa, le kwa botlhaba ke Letsha la Tanganyika. [12]

Bontsi jwa kgaolo e ke sekgwa sa miombo, mme ditlhare tsa Brachystegia spiciformis le Julbernardia globiflora ke tsone tse di leng kwa godimo. Go na le mafelo a mantsi a a tletseng ka metsi a a tletseng ka bojang mo bogareng jwa Malagarasi-Moyowosi basin, le go bapa le noka ya Ugalla go ya kwa borwabophirima. [13]

Ditso

[fetola | Fetola Motswedi]

Go ya ka moithutatlholego Rosemary Lowe-McConnell, "Malagarasi le Noka ya Rungwa go tsewa gore ke metswedi ya metsi a a tswang kwa pele ga lekgwamolelo la Zaire". Malagarasi e simolotse pele ga Letšha la Tanganyika mme e ne e le karolo ya Noka ya Congo go ya kwa bophirima. Go tloga ka nako eo go ne ga bolelwa gore Letsha la Tanganyika le ne la "fetoga le bo la boela morago, le ne la ntsha matlapana a masha, la fetola noka ya delta, le go fetola tsela e noka e elelang ka yone".[1] Go ralala ditso tsa yone, bogodimo jwa letsha bo fetogile thata magareng ga dimetara di le lekgolo le makgolo a mabedi (330 le 660 ft); dipego tsa hisetori tsa kwa bokhutlong jwa ngwagakgolo wa lesome le borobongwe di supa gore e ne e le bogodimo jwa dimetara di le lesome (33 ft) go feta gompieno.[1]

Setso

[fetola | Fetola Motswedi]

Ditso tsa lefelo leo di bitsa Malagarasi di re ke "noka ya meya e e bosula". Kwa bokhutlong jwa ngwagakgolo wa bo lesome le borobabobgwe , batho ba Wavinza, ba ba neng ba tsamaisa tirelo ya mokoro wa noka go tswa kwa lobopong lo lo kafa molemeng, ba ne ba tila go kopanngwa le batho ba Wanyamwezi ka ntlha ya sekgoreletsi sa tlholego se se dirilweng ke Malagarasi. 17] Gape kwa lobopong lo longwe e ne e le Wangoni (Watutu Zulu).[ 18] Henry Morton Stanley, yo o neng a tsaya barongwa ba le botlhokwa mo "tirong ya tlhabologo" ya Afrika, o ne a bolela gore barongwa ba ne ba ka latela Malagarasi mme ba tsaya karolo mo "maetong a go sokololela kwa Uvinza, Uha, le Ugala". 19]
