Erozyon Nedir? <\/p>\n
Erozyon (toprak a\u015f\u0131n\u0131m\u0131), topra\u011f\u0131n a\u015f\u0131nmas\u0131n\u0131 \u00f6nleyen bitki \u00f6rt\u00fcs\u00fcn\u00fcn yokedilmesi sonucu koruyucu \u00f6rt\u00fcden yoksun kalan topra\u011f\u0131n su ve r\u00fczgar\u0131n etkisiyle a\u015f\u0131nmas\u0131 ve ta\u015f\u0131nmas\u0131 olay\u0131d\u0131r.

TEMA’n\u0131n erozyonla m\u00fccadeleye bu kadar \u00f6nem vermesinin alt\u0131nda, erozyonun \u00fclkemizin ya\u015fam ko\u015fullar\u0131n\u0131 olumsuz etkileyecek kadar b\u00fcy\u00fck bir tehlike olmas\u0131 yatmaktad\u0131r. Erozyon, T\u00fcrkiye’nin g\u0131da a\u00e7\u0131s\u0131ndan kendine yeterli bir \u00fclke olmas\u0131n\u0131 tehlikeye d\u00fc\u015f\u00fcrmektedir. \u00dclkemizin topraklar\u0131n\u0131n % 63’\u00fc \u00e7ok \u015fiddetli ve siddetli erozyon tehlikesine maruzdur. R\u00fczgar ve ya\u011fmur, verimli topraklar\u0131 s\u00fcr\u00fckleyerek, baraj g\u00f6llerine, akarsu yataklar\u0131na ve denizlere ta\u015f\u0131maktad\u0131r. \u00dclke y\u00fczeyinden bir y\u0131lda kaybedilen toprak miktar\u0131 yakla\u015f\u0131k 1.4 milyar tondur. Bu topraklarla birlikte mineral ve organik madde de kaybedilmektedir. T\u00fcrkiye’nin kimyevi g\u00fcbrelere ay\u0131rd\u0131\u011f\u0131 y\u0131ll\u0131k kayna\u011f\u0131n 4.5 trilyon lira oldu\u011fu d\u00fc\u015f\u00fcn\u00fcl\u00fcrse, ekonomik kayb\u0131n b\u00fcy\u00fckl\u00fc\u011f\u00fc daha net anla\u015f\u0131labilir. Erozyonla kaybedilen bir ba\u015fka de\u011fer ise sudur. Kaybolan toprak y\u00fcz\u00fcnden her y\u0131l yakla\u015f\u0131k 50 milyar m 3 ya\u011f\u0131\u015f depolanamamaktad\u0131r. <\/p>\n
Erozyon toplumsal sorunlar\u0131n artmas\u0131na da yol a\u00e7maktad\u0131r. Yanl\u0131\u015f arazi kullan\u0131m\u0131, tar\u0131m alanlar\u0131n\u0131n verimini azaltmaktad\u0131r.

K\u00f6yden kente g\u00f6\u00e7 ise, alt yap\u0131n\u0131n yetersiz oldu\u011fu kentlerdeki ekonomik ve toplumsal sorunlar\u0131 daha da a\u011f\u0131rla\u015ft\u0131rmaktad\u0131r. <\/p>\n
Barajlar ve yeralt\u0131 sular\u0131 da, erozyonun etkilerinden nasibini almaktad\u0131r. Yerinden kopup giden topraklar, baraj g\u00f6llerini doldurarak su depolama hacimlerini azaltmakta ve barajlar\u0131n \u00f6mr\u00fcn\u00fcn k\u0131salmas\u0131na neden olmaktad\u0131r. Erozyon sonucunda topra\u011f\u0131n alt\u0131ndaki cans\u0131z tabaka (ana kaya) ortaya \u00e7\u0131kmaktad\u0131r. Faydal\u0131 toprak katmanlar\u0131n\u0131 kaybeden arazilerde \u00e7\u00f6lle\u015fme ba\u015flamaktad\u0131r.
