L'applicazione del concetto di ecosistema consente, infatti, di rappresentare e analizzare la realtà agraria come gerarchia di agroecosistemi. In questo contesto il livello di organizzazione dell'azienda agraria è stato assunto come strategico per concepire e realizzare uno sviluppo sostenibile dell'ambiente rurale. Nell'opera vengono illustrati i criteri teorici e le applicazioni pratiche per organizzare l'azienda come agroecosistema multifunzionale, in conformità con i principi di ecosviluppo che gli autori hanno maturato attraverso l'esperienza conseguita in un ventennio di ricerca sul campo. Il volume tratta, inoltre, di aspetti poco conosciuti, come il ruolo esercitato dalle siepi e dai sistemi policolturali, che sono essenziali per la realizzazione di agroecosistemi ecocompatibili basati sulla biodiversità. L'ultima parte del libro, infine, è dedicata al caso studio riguardante l'agricoltura biologica come esempio di agricoltura ecocompatibile. 606 2 $aEcologia agraria 606 2 $aAgricoltura biologica 676 $a577.55$v(22. ed.)$9Ecologia degli ambienti creati dall'uomo 700 1$aCaporali,$bFabio$075991 701 1$aCampiglia,$bEnio$0445761 701 1$aMancinelli,$bRoberto$0445762 801 0$aIT$bUniversità della Basilicata - B.I.A.$gRICA$2unimarc 912 $a000030489 996 $aAgroecologia$993665 997 $aUNIBAS BAS $aAGRARIA CAT $aLCR$b01$c20120126$lBAS01$h0724 CAT $aTTM$b30$c20120302$lBAS01$h1052 FMT Z30 -1$lBAS01$LBAS01$mBOOK$1BASA2$APolo Tecnico-Scientifico$2DID$BDidattica$3PTS.s2.p19.24$6110425$5T110425$820120223$f98$FConsultazione Z30 -1$lBAS01$LBAS01$mBOOK$1BASA2$APolo Tecnico-Scientifico$2DID$BDidattica$3PTS.s2.p19.24A$6110426$5T110426$820120223$f04$FPrestabile Didattica LEADER 05135nam 22006014a 450 001 9910143746603321 005 20170815121744.0 010 $a1-280-27629-0 010 $a9786610276295 010 $a0-470-02012-1 010 $a0-470-02009-1 035 $a(CKB)1000000000356109 035 $a(EBL)239045 035 $a(OCoLC)299571228 035 $a(SSID)ssj0000137364 035 $a(PQKBManifestationID)11954167 035 $a(PQKBTitleCode)TC0000137364 035 $a(PQKBWorkID)10088037 035 $a(PQKB)10883709 035 $a(MiAaPQ)EBC239045 035 $a(EXLCZ)991000000000356109 100 $a20040326d2004 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 00$aDesigning cdma2000 systems$b[electronic resource] /$fLeonhard Korowajczuk ...

CDMA technology is complex to design due to its inherent adaptive characteristic and the introduction of data requires a complete new way of analysing the network from traffic characteristics to performance requirements.
