Metsi mo Aforika
Metsi mo Aforika ke kgang e e botlhokwa e e akareditseng metswedi, go anamisiwa ga one le tiriso e e tshwanetseng ya metswedi mo kontineteng. Aforika o na le boferabongwe mo lekgolong la metswedi ya metsi a phepa le lesome le borataro mo lekgolong la palo ya batho mo lefatsheng ka bophara.[1][2] Dingwe tsa dinoka tsa Aforika ke noka ya Congo, ya Nile, Zambezi, Niger le ya Victoria e e le yone ya bobedi ka botona mo lefatsheng lotlhe ka bophara. Le fa go ntse jalo kontinente ya Aforika ke yone e e omeletseng go gaisa tse dingwe tsotlhe mo lefatsheng, ka di milione tsa batho ba Aforika ba ba santseng ba sokodisiwa ke tlhaelo ya metsi ngwaga yotlhe.[3]

Tlhaelo e e bakiwa ke mathata a go tlhoka go isa metsi ko bathong ka tsela e e lolameng, go gola ka pele ga dipalo tsa batho le go tlhoka taolo e e siameng ya metswedi e e leng teng. Nako tse dingwe go na le palo e potlana ya batho ba ba nnang mo lefelong le le nang le metsi a mantsi. Sekai, masome a mararo mo lekgolong la metsi a kontinente a ko kgampung ya Congo e go nnang batho ba le lesome mo lekgolong la palo ya batho ba Aforika.[4][3]Go na le pharologano e tona fa go lebelelwa ka pula e nang ka teng mo mafelong a farologaneng le ka dinako tse di farologaneng. Go mowafala ga metsi a a emang mo mmung le gone go diragala ka bofefo mo mafelong mangwe, se se baka gore go na ga pula go ye tlase mo mafelong a o.[5][4] Le fa go ntse jalo go na le temosego ya go farologana thata mekgwa ya seemo sa bosa le metswedi ya metsi lefatshe ka bophara, ka jalo le fa mafelo mangwe a na le metsi a a lekaneng,[2] kgaolo ya Sub-Sahara mo Aforika e lebannwe ke dikgwetlho tse dintsi tsa metsi tse di kganelang kgolo ya itsholelo di bo di tshosetsa matshelo a batho ba kontinente e.[2] Temothuo mo Aforika e ikaegile ka pula, mme lefatshe le le tlhagotsweng le bo le nosediwa ke la palo e eko tlase ga lesome mo lekgolong.[1][2] Go amiwa ke phetogo ya seemo sa bosa le pharologano di kwa godimo thata.[2] Motswedi wa motlakase o o tlwaelesegileng thata ke wa metsi.[2] Letamo la Kainji ke lengwe la metswedi ya motlakase o o fetlhilweng ka metsi o o dirisiwang go isa motlakase kwa ditoropong tse dikgolo kwa Nigeria le lefatshe lele bapileng le lone la Niger. [6]Ka jalo go nnile le dipeeletso tse dintsi mo dingwageng tse di lesome tse di fitileng e le tsela ya go oketsa motlakase o o fetlhiwang. [2]
Ditharabololo tsa dikgwetlho tsa go drisa metsi go fetlha motlakase le tshireletsego ya dijo di paledisiwa ke mathata a dikago tsa metsi, tlhabololo le kitso ya baeteledipele go mekamekana le palo ya batho e e golelang pele mme edile e tlhoka metsi.[2] Se se dirwa gape ke gore Aforika o fetogela kwa go tlhabololeng metse o e dira ditoropo ka bofefo.[2][7]Tlhabololo e e amanang le metsi ga mmogo le tlhokomelo ga di motlhofo ka ntata ya gore go na le metswedi ya metsi e mentsi e motswedi o le mongwe o kgonang go nna mo mafatsheng a le mantsi (dinoka, makadiba le maje a a ntshang metsi).[2] Masome a supa le botlhano mo lekgolong jwa sub-Saharan Africa bo wela mo mafelong a le masome a matlhano le boraro a dikgampu tse di akaretsang melelwane e le mentsi.[1][2]Kgwetlho e e ka fetolwa go nna tshono ya ditlhabologo fa go na le kgonagalo ya tirisanommogo mo mafatsheng a motswedi o leng mo go one.[2] Tshekatsheko ya makgamu a a farologaneng ya noka ya Zambezi e le sekai, e supa fa tirisanommogo ya mafatshe a e leng mo go one e ka tsisa koketsego mo go fetlheng motlakase ka masome a mabedi le boraro mo lekgolong ntle le dipeeletso dipe di sele.[1][2] Melao ya tirisanommogo ya mafatshe e teng, jaaka wa Zambezi River Authority, South African Development Community (SADC) Protocol, Volta River Authority le Nile Basin Commission.[2] Le fa go ntse jalo, maiteko a mangwe a tlhokafala go tlhabolola maikaelelo a sepolotiki le maatla a madi le melao e e ka tsisang phenyo mo go botlhe ba ba amegang.[2]
Metswedi ya metsi
fetolaMetsi a a kwa tlase ga lefatshe
fetolaMetsi a a kwa tlase ga lefatshe a botlhokwa thata mo go tshegetseng kanamiso ya metsi le matshelo a batho mo Sub-Saharan Africa bogolo jang ka a apesitse bophara jwa lefelo, a nang e boleng jo bo kwa godimo le bokgoni jwa go emelela ka dinako tsa lenyora ele go gola ga dipharologano tsa phetogo ya seemo sa loapi.
Go na le metswedi e le palo potlana e e ntshang metsi a a phepa mo Aforika, nngwe ya dipatlisiso tse di dirilweng ka ngwaga wa 2007 e supile fa masome a mane mo lekgolong le go feta a batho ba Aforika ba dirisa metsi a a kwa tlase ga lefatshe e le one a a nowang thata, bogolo jang kwa bokone le borwa jwa mafatshe a a Aforika.[8][9][10]
Fa dipopego tsa metsi a a kwa tlase ga lefatshe le phetogo ya seemo sa loapi sa kgaolo nngwe di supa go nna teng le go ntshafatsa metsi a a kwa tlase ga lefatshe, boleng le bokete jwa metsi mo isagong go tla laolwa ke tiriso ya lefatshe le taolo ya metsi mo sechabeng.
Dimpompo e santse e le tsone motswedi o o botlhokwa wa metsi a a nowang (39%) mo ditoropong, mme botlhokwa jwa didiba bo golela kwa godimo (24%).[8] Mokgatlho wa WHO (2006) o boletse fa ka ngwaga wa 2004, lesome le borataro mo lekgolong fela la batho ba sub-saharan Africa ba kgona go bona metsi a a nowang a tswa mo dimpompong tse di mo matlong kgotsa mo malwapeng. Le fa go na le metsi mo mafelong a, ga go motlhofo go bona metsi a a babalesegileng go nowa ka go na le botlhabetsi jwa go leswafala ka ntlha ya mabaka a mantsi. Mabaka a tshwana le go tlhoka go tlhokomelwa ga dipompo ka ntlha ya letlhoko la madi, kgotlhelesego le go tlhoka kgopo ya metsi a a leswe nako tse dingwe ka ntata ya tlhaelo ya madi. Fa didiba di agiwa le didiriwa tsa kgopo ya metsi a a leswe di agiwa, nako tse dingwe boleng jwa metsi ga bo tlholwe jaaka go tlhokega, mme gape batho ga ba rutiwe ka go dirisa metsi a.[11]
Metsi a a fa godimo ga lefatshe
fetolaLekgotla la mafatshefatshe la botsogo (World Health Organisation - WHO) le ne la bega ka ngwaga wa 2015 fa batho ba le dimilione di le lekgolo le masome a matlhano le boferabongwe ba a ga metsi a a sa tlhatswiwang a a fa godimo ga lefatshe jaaka makadiba, megobe, dinoka le melapo lefatshe ka bophara. Metswedi ya metsi a a fa godimo ga lefatshe mo Aforika gantsi a a bo a kgotlhelesegile ka ntata ya lookwane, madirelo le leswe la mantlo a boithomelo le tse dingwe. Sekai, Niger Delta e e leng legae la madirelo a lookwane kwa Nigeria, le lookwane lwa dimilione di le pedi lo tlhotlhiwang mo lefelong leo letsatsi le letsatsi, metsi a yone a kgotlhelesegile ka ntata ya go tshologa ga lookwane.[12]
Metsi, Ditiro le Itsholelo
fetolaAforika e sa tswa go itemogela dingwaga tse di lesome tse di gaisang (2005 - 2015) tsa kgolo ya itsholelo fa e sale morago ga boipuso. Kgolo e l fa go ntse jalo ga e akaretse ebile ga e lekalekanye.[2] Go ya ka World Bank, kgolo ya GDP mo sub-saharan Africa e ne e le mo palong ya 4.5% go tswa kwa go 4.2% ka ngwaga wa 2013, e engwe nokeng ke go beeletsa madi mo dikagong le thobo e e ileng kwa godimo ya temothuo.[2]
