Ayingawo onke amazwe ehlabathi enza ngokulinganayo iziphumo ezahlukileyo zotshintsho lwemozulu. ISpain lelinye lamazwe apho ubushushu busebenza ngamandla ngakumbi nangakumbi. Ngelixa kwamanye amazwe imisitho yokutshisa ubushushu ihlala ihlala phakathi kweentsuku ezi-3 ukuya kwezi-4, eSpain zihlala phakathi kwe-4 neye-5.
Uphononongo lwenziwe apho IZiko lokuchongwa kweNdalo esingqongileyo kunye neziFundo zaManzi zeBhunga eliPhakamileyo loPhando lwezeNzululwazi (CSIC) kwaye ipapashwe kwiphephancwadi lezenzululwazi i-Environmental Health Perspectives, ehlalutye amaza obushushu awenzeka phakathi kowe-1972 nowama-2012 kumazwe ali-18 apho ezi ziganeko zemozulu zigqithisileyo zixhaphake khona. Bafumene ziphi iziphumo?
Kwisifundo esenziwe, amanani obushushu alinganiswe yi-State Meteorological Agency yazo zonke iingqukuva zephondo ziye zavavanywa. Njengakwimbalela, akukho nkcazo yehlabathi jikelele yokuba yintoni ubushushu obushushu. Nangona kunjalo, isifundo sisekwe kwimiba elishumi elinambini ekuvunyelwene ngayo luluntu lwenzululwazi.
Ngokwedatha efunyenwe emva kwalo lonke ubhaliso, elona zinga liphezulu lamaza obushushu athathwa yiSpain ukuba, emva kweTshayina, khokela uluhlu lwamazwe apho kushushu khona amaza obushushu amaninzi kuba kukho iirekhodi. Ayisiyiyo loo nto kuphela, kodwa ukwanda kokuhamba rhoqo kunye nokuqina kwezi ziganeko zigqithileyo kunyuke ngokubonakalayo ukusukela ngo-2003.
Oku kunyuka kwamaza obushushu kwaxelwa kwangaphambili zizazinzulu njengeziphumo zotshintsho lwemozulu. Njengokuba ubushushu behlabathi bonyuka, iziphumo zotshintsho lwemozulu ziyagxininiswa. E-Spain kuye kwakho umndilili wamaqondo obushushu angama-32 ngonyaka.
Indawo yaseSpain apho ezi zinto zigxile kakhulu ikwicala elisemazantsi ePeninsula. Umngcipheko kunye nezinga lokufa kumaza obushushu nawo enyukile.
ISpain, njengoko besesitshilo kumaxesha amaninzi, lilizwe elisemngciphekweni kakhulu kutshintsho lwemozulu kwaye emva kokufunda kunye neerekhodi ezenziwa zizazinzulu bayakuqinisekisa oko.
