Utshintsho lwemozulu luya kuchaphazela ukhenketho kunye nendawo eziphila kuyo elwandle

ukunyuka kwenqanaba lolwandle ngenxa yotshintsho lwemozulu

Iziphumo zotshintsho lwemozulu njengokunyuka kwamaqondo olwandle, amaqondo aphezulu obushushu bamanzi, ukuphakama kwamaza, kunye nokunyuka kwamaxesha kunye nokuqina kweziganeko ezigabadeleyo kuya kuchaphazela ukhenketho kunye nezinto eziphilayo zolwandle.

Ezi ziphumo zotshintsho lwemozulu Sele bekho kuLwandle lweMeditera, ngakumbi kwinxalenye yeValencia. UMiguel Rodilla yi-biologist evela kwiYunivesithi yasePolytechnic yaseValencia kwaye uphawule ukuba zonke izakhiwo, iindawo ezihamba phambili kunye nemimandla yaseValencia kuya kufuneka zitshintshe inkangeleko yazo yangoku ukuze zilungelelane neziphumo zotshintsho lwemozulu.

Unxweme lwaseValencia

Into yokuqala kukuziqhelanisa nokunyuka kwamanqanaba olwandle. Ukwenza oku, kungcono ukuba uhlengahlengise kule minyaka idlulileyo kwaye utshintshe ulwakhiwo kancinci kancinci, ukuze iindleko zoqoqosho zingothusi okanye zingqale ngqo. Ukushiya unxweme lolwandle yeyona nto iphambili kuba isoyikiso ayisiyiyo eyokunyuka kuphela komgangatho wolwandle, kodwa ngamanzi amaninzi, izaqhwithi ziya kutshabalalisa yonke into esemendweni wabo.

Ngokumalunga nokunyuka kwamaqondo obushushu bamanzi olwandle, sinokunyamalala kweentlobo ezininzi eziqhelekileyo kunye nokubonakala kwezinye izinto ezininzi ezivela kwiindawo ezikude njengamanzi akweleenjiko okanye uLwandle Olubomvu.

IMeditera inovakalelo ngokukodwa kwimeko ye-acidification eqhutywa lutshintsho lwemozulu, ethatha ukwanda kobumuncu bamanzi, ngenxa yokunyuka kwekhabhon dayoksayidi kwiatmosfera. Oku kukwabangela ukwanda okucacileyo kukwahlulahlula amanzi. Iqulathe ekubeni kukho ubunzima obukhulu emanzini ukuze ukwazi ukuxuba, oko kukhokelela kwingxaki yokufumaneka kwezondlo.

Ukwanda kokufa kweentlobo kunye nokuziqhelanisa

Ngenxa yezi zizathu zikhankanywe apha ngasentla, ukwanda kokufa kuye kwabhalwa kwiintlobo ezininzi ezinjengee-gorgoni kunye nezinye iintlobo ezinje nge-calcareous algae ezinobunzima bokuphila (oku kungenxa yokuba i-algae ifuna ukugxila okuphezulu kwe-calcium carbonate engasasebenziyo ukwanda kwe-CO2 emanzini).

Ukunyuka kwenqanaba lolwandle Izakutshintsha amalwandle kunye notshintsho kumaza nobukhulu bezaqhwithi iya konakalisa kwaye ibangele iingxaki kwizakhiwo zonxweme. Ukonyuka okuncinci kweli nqanaba kunokuchaphazela kakhulu i-aquifer yaselunxwemeni kwaye kuvelise iingxaki zokufumaneka kwamanzi amatsha.
