Cijelim svojim bi\u0107em i\u0161\u010dekujem povratak na ovo \u010darobno mjesto mira i ti\u0161ine. Ovdje, gdje je priroda svemo\u0107na, gdje se voda spaja s nebom, a rijeka isprepli\u0107e sa zelenilom. Nikad nisam iskusila snagu ove vrste \u2013 navikav\u0161i se na more, koje \u0107e za mene uvijek imati posebno mjesto, ovdje sam susrela posve novo lice snage u obliku brze, nestvarno \u010diste, hladne teku\u0107ice.<\/p>\n\n\n\n

Priroda se ovdje prilagodila i promijenila u skladu s uvjetima, priroda je ovdje cvjetala i sjajila, puna snage i rasko\u0161i \u0161to ju je voda podarila ovome mjestu.<\/p>\n\n\n\n

Danas je Svjetski dan borbe protiv su\u0161e i dezertifikacije. Neki smatraju da su me\u0111unarodni dani umjetni pojmovi koji ne donose promjenu niti rje\u0161avaju problem, no za\u0161to gledati na taj na\u010din? Za\u0161to ne bismo iskoristili mogu\u0107nost da na ovakve dane upoznamo druge sa stvarnim problemom? Za\u0161to ne prihvatiti izazov i jedan dan u godini u\u010diniti druga\u010dijim od ostalih? Da 17. lipnja nije bio progla\u0161en danom borbe protiv su\u0161e i dezertifikacije, moja bi dana\u0161nja tema vjerojatno bila druga\u010dija.<\/p>\n\n\n\n

Dezertifikacija (lat. desertum<\/em> : pustinja) ozna\u010dava trajno i nepovratno smanjenje produktivnosti tla. Su\u0161a, pak, predstavlja privremenu degradaciju zemlje u suhim predjelima, a pritom se vegetacija nakon oborina ponovno razvija.<\/p>\n\n\n\n

Iako su ljetne su\u0161e u nekim dijelovima Hrvatske prili\u010dno o\u0161tre, jo\u0161 uvijek se ne trebamo bojati susreta s pravom dezertifikacijom.<\/p>\n\n\n\n

Su\u0161na podru\u010dja podlo\u017ena dezertifikaciji postoje na svim kontinentima osim Antarktike. Ve\u0107ina njih pokriva sjevernu i ju\u017enu Afriku, zapadnu stranu Sjeverne Amerike, Bliski Istok i sredi\u0161nju Aziju, a postoje i u nekim dijelovima Ju\u017ene Amerike (primjerice Argentina) i Europe (\u0160panjolska).<\/p>\n\n\n\n

Iako sam pojam dezertifikacije zvu\u010di nestvarno, daleko od na\u0161e stvarnosti \u2013 jer se one \u201eprave\u201c, tipi\u010dne pje\u0161\u010dane pustinje iz dokumentarnih filmova nalaze daleko preko mora i oceana \u2013 on ne ozna\u010dava doslovno \u0161irenje povr\u0161ine pustinje. Dezertifikaciju obilje\u017eavaju razli\u010diti procesi koji zajedno vode k trajnoj degradaciji su\u0161nih i polusu\u0161nih podru\u010dja, uklju\u010duju\u0107i travnjake i \u0161ikare, te uzrokuju smanjenje kakvo\u0107e tla, vode, flore i faune.<\/p>\n\n\n\n

Postoje brojni razlozi koji \u010desto djeluju zajedno te uzrokuju degradaciju tla i dezertifikaciju.<\/p>\n\n\n\n

Primjerice, deforestacija, odnosno kr\u010denje \u0161uma, pretjerana ispa\u0161a, neregulirano navodnjavanje, nedovoljno dobro organiziran uzgoj biljnih kultura te klimatske promjene.<\/p>\n\n\n\n

Re\u017eimi oborina zbog klimatskih se promjena drasti\u010dno mijenjaju diljem svijeta, su\u0161e postaju dugotrajnije i te\u017ee, \u010dime se dezertifikacija tako\u0111er poja\u010dava.<\/p>\n\n\n\n

Klimatske promjene, koje su velikim dijelom zasluga \u010dovjeka, dovode do toplijih i \u010desto su\u0161nijih razdoblja nego neko\u0107, \u0161to dovodi do \u010de\u0161\u0107ih po\u017eara i lo\u0161ije kvalitete tla. Naime, u takvim uvjetima tlo te\u017ee zadr\u017eava vodu i hranjive tvari, \u0161to smanjuje mogu\u0107nost zadr\u017eavanja vegetacije i pospje\u0161uje dezertifikaciju.<\/p>\n\n\n\n

Ovaj pojam tako\u0111er podrazumijeva smanjenu mogu\u0107nost uzgoja. Su\u0161na podru\u010dja dom su oko 2,7 milijarde ljudi, od kojih ve\u0107ina nastanjuje zemlje u razvoju. Mnogi od njih \u017eive u neima\u0161tini i ovise upravo o obradivoj zemlji.<\/p>\n\n\n\n

Kao svaki okoli\u0161ni problem, dezertifikaciju je bolje sprije\u010diti nego nastojati vratiti okoli\u0161 u prija\u0161nje stanje. Poku\u0161aji oporavka takvih podru\u010dja pokazali su se skupocjenima, a rezultati nisu bili vrlo uspje\u0161ni.<\/p>\n\n\n\n

Jedan od na\u010dina sprje\u010davanja dezertifikacije je o\u010duvanje \u0161uma i drugih tipova vegetacije kako bi se tlo o\u010duvalo od erozije vjetrom i vodom. Postoje brojne druge metode o\u010duvanja podru\u010dja kojima prijeti dezertifikacija, no jedno je jasno: da su ljudi posve svjesni njenih posljedica, dvaput bi razmislili prije nego \u0161to bi djelovali protiv prirode.<\/p>\n\n\n\n

Iako Hrvatska i dalje nema ovakve probleme, geografski nismo daleko od njih. Su\u0161na podru\u010dja postoje u \u0160panjolskoj, nekim dijelovima Gr\u010dke, Turske itd. Na\u0161e je more ve\u0107 pokazalo zna\u010dajan porast temperature. S vremenom i s nastavkom klimatskih promjena, na\u0161a bi se zemlja mogla susresti sa sli\u010dnim problemima.<\/p>\n\n\n\n

Mo\u017eda zbog svega navedenog trenutno dezertifikacija nije razlog na\u0161e zabrinutosti, no to ne zna\u010di da imamo pravo ne znati ni\u0161ta o njoj \u2013 i zasigurno nam ne daje pravo da djelujemo protiv prirode: da sje\u010demo \u0161ume kad i kako po\u017eelimo, da se nesavjesno i nepromi\u0161ljeno bavimo uzgojem i obra\u0111ivanjem zemlje, da djelujemo na na\u010dine koji poti\u010du daljnje klimatske promjene.<\/p>\n\n\n\n

Svaki problem u prirodi je takav, i vjerojatno \u0107u ovo pisati ponovno i ponovno \u2013 trebamo razumjeti, nau\u010diti, i zatim djelovati. Kako bismo mogli unijeti promjenu, trebamo u\u010diti druge i podizati njihovu svijest.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Te\u0161ko je re\u0107i da jedna osoba mo\u017ee ne\u0161to promijeniti.<\/p>\n\n\n\n

Jednako je te\u0161ko re\u0107i da jedna osoba, ti, ja, ne mo\u017ee promijeniti ni\u0161ta.<\/p>\n\n\n\n

Ako je ve\u0107 jednako te\u0161ko re\u0107i i prihvatiti bilo koju od ovih misli, odlu\u010dujem se za prvu. Nemam ni\u0161ta za izgubiti i sve za dobiti.<\/p>\n\n\n\n
