Indawo emitsha kunye nengqondo yokucinga ngengqondo yanamhlanje I-Beemster Polder ibinempembelelo enzulu nehlala ihleli kwiiprojekthi zokubuyisela kwimeko yesiqhelo eYurophu. Ukudalwa kwe-polder kuphawula inyathelo eliphambili kunxibelelwano phakathi kwendoda kunye namanzi ngexesha elibalulekileyo lokwanda kwentlalo noqoqosho.
I-polder lulwandiso lomhlaba ohlangulwe kwakhona elwandle. Kwaye kuyo yonke imbali yaseHolland, egcwele amachibi kunye neelittas ezihlala uninzi lomhlaba, ukutyhubela iinkulungwane lo mhlaba wenziwa wahlalwa ngokuvuselelwa komhlaba kunye nokukhuselwa emanzini.
Kwiihektare ezizigidi ezi-3,4 iNetherlands namhlanje eyakha isinye kwisithathu zingaphantsi komphakamo wolwandle. Ukuba bekungakhange kwakhiwe iidiziki kwaye ukuba bekungekho amanzi angaphezulu, i-65% yelizwe namhlanje ibingaphantsi kwamanzi.
Indawo eselunxwemeni emantla eMntla Holland Kop van kunye noLwandle lwaseWadden yayikhe yangumdibaniso wonxibelwano lomgxobhozo ololulele emazantsi-ntshona eDenmark. Isidingo 'sokwenza' umhlaba omtsha savela kumonakalo obangelwe zizikhukula eziqhubekayo, kunye nesibonelelo esongeziweyo sokufumana umhlaba olungileyo weefama.
Zintlanu izinto ezichaphazele inkqubo yokubuyiselwa komhlaba: ukufumaneka kwemali eyinkunzi yotyalo-mali, uzinzo kubudlelwane bezopolitiko nezoqoqosho, kunye nokufumaneka kweendlela zobuchwephesha, umoya wokurhweba, kunye namaxabiso amahle omhlaba wezolimo.
Idabi lokulwa amanzi laqala kumantla eNyakatho Holland, kwindawo engaphezulu kwamanzi avulekileyo e-IJ yangaphambili (Hollands Noorderkwartier), ngokugcina amanzi olwandle ngaphandle. Ukuqala ngenkulungwane ye-16 iinzame zazijolise kumachibi nakwimachibi okuhambisa amanzi ngaphakathi elizweni. Ulungiso lomhlaba lwenziwa ngokufunxa iLake Great, ngakumbi kwinxalenye esemantla yeHolland.
Le nkqubo yenziwe yaphucuka ngokuqatha kwitekhnoloji yokumpompa kunye neyokuhambisa amanzi ukusuka kumatshini omoya ohamba ngesanti kubunzulu baphantsi.
