20.500.12556/RUL-187167 Podnebne projekcije agroklimatskih kazalnikov raziskovalni podatki projekta Climate projections of agroclimatic indicators project research data Raziskovalni podatki so bili zbrani in ustvarjeni v okviru raziskav projekta Podnebne projekcije agroklimatskih kazalnikov. Na podlagi meteoroloških podatkov za preteklo obdobje 1981–2010 in podnebnih projekcij za scenarija RCP4.5 in RCP8.5 so bili za koruzo in ozimno pšenico izračunani agroklimatski kazalniki, ki opisujejo temperaturne razmere, vročinski stres, padavinske in sušne razmere, pozebo ter pogoje prezimovanja (delovna sklopa DS1 in DS2). Podatki o pridelkih, lastnostih tal in fenološkem razvoju rastlin so bili uporabljeni za kalibracijo modela pridelka AquaCrop za slovenske razmere (delovni sklop DS3). Za natančno kalibracijo modela so bile izmerjene tudi vodnozadrževalne lastnosti tal na obeh obravnavanih lokacijah. Kalibrirani model omogoča simulacijo odziva pridelka na različne podnebne scenarije ter ocenjevanje vplivov podnebnih sprememb na kmetijsko proizvodnjo. Rezultati raziskave potrjujejo, da bodo podnebne spremembe pomembno vplivale na rastne razmere za pridelavo koruze in pšenice v Sloveniji. Projekcije kažejo na podaljševanje rastne dobe, povečevanje temperaturnih vsot ter izrazito povečanje pogostosti vročinskih obremenitev rastlin. Največje spremembe so predvidene v jugozahodni, osrednji in vzhodni Sloveniji, še posebej v scenariju intenzivnejšega segrevanja RCP8.5. Pri padavinskih kazalnikih so spremembe manj enoznačne, vendar rezultati nakazujejo povečanje intenzivnosti močnih padavinskih dogodkov. Kazalniki pozebe in prezimovanja kažejo splošno zmanjševanje hladnih razmer, vendar rezultati opozarjajo, da se lahko zaradi zgodnejšega fenološkega razvoja rastlin tveganje za poškodbe zaradi pozebe ponekod ohrani ali celo poveča. Podatkovni sklop predstavlja pomemben znanstveni in strokovni rezultat projekta ter omogoča nadaljnje raziskave vplivov podnebnih sprememb na kmetijstvo, pripravo ocen podnebne ranljivosti in tveganj ter podporo odločanju na področju kmetijske politike in zagotavljanja prehranske varnosti. Razvita metodologija in podatkovne zbirke so uporabne tudi za raziskave drugih kmetijskih kultur ter sorodnih področij, kot so sadjarstvo, vinogradništvo, gozdarstvo in upravljanje krajine. The research data were collected and generated as part of the research carried out under the project ‘Climate Projections of Agroclimatic Indicators’. Based on meteorological data for the period 1981–2010 and climate projections for the RCP4.5 and RCP8.5 scenarios, agroclimatic indicators were calculated for maize and winter wheat, describing temperature conditions, heat stress, precipitation and drought conditions, frost damage and overwintering conditions (WP1 and WP2). Data on yields, soil properties and plant phenological development were used to calibrate the AquaCrop yield model for Slovenian conditions (WP3). To calibrate the model accurately, the water-retention properties of the soil were also measured at both sites under consideration. The calibrated model enables the simulation of crop responses to various climate scenarios and the assessment of the impacts of climate change on agricultural production. The research results confirm that climate change will significantly affect growing conditions for maize and wheat production in Slovenia. Projections indicate a lengthening of the growing season, an increase in temperature sums and a marked increase in the frequency of heat stress on plants. The greatest changes are predicted in south-western, central and eastern Slovenia, particularly under the RCP8.5 scenario of more intense warming. For precipitation indicators, the changes are less clear-cut, but the results suggest an increase in the intensity of heavy rainfall events. Indicators of frost and overwintering show a general reduction in cold conditions; however, the results warn that, due to earlier phenological development of plants, the risk of frost damage may be maintained or even increased in some areas. The dataset represents a significant scientific and technical outcome of the project and enables further research into the impacts of climate change on agriculture, the preparation of climate vulnerability and risk assessments, and decision-making support in the fields of agricultural policy and food security. The methodology and datasets developed are also useful for research into other crops and related fields, such as fruit growing, viticulture, forestry and landscape management. agroklimatski kazalniki podnebne projekcije podnebne spremembe poljščine količina pridelka modeli pridelka poljščin Aquacrop agroclimatic indicators climate projections climate change crops crop yield crop yield models Aquacrop true false false Slovenski jezik Angleški jezik Ljubljana, meritve vode v tleh na lokacijah Jablje in Rakičan, Slovenija / Ljubljana, soil water measurements at Jablje and Rakičan, Slovenia Trajanje projekta od septembra 2024 do avgusta 2026, terenski poskus (meritve vode v tleh) v avgustu 2026 / Project duration from September 2024 to August 2026, field experiment (soil water measurements) conducted in August 2026 Neznano 2026-09-09 09:47:05 2026-09-10 21:18:05 2026-09-11 04:28:07 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2026-09-25 PREBERI_ME.txt PREBERI_ME.txt PREBERI ME 1 95C579A47D4979AA876E7F7B51988401 cb85a4098e4b769d09d6b8df1a52cd9a80e8dee1891757ee3f3fac0772960c2f f0a3074a-ac3a-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246755 README.txt README.txt README 1 B8D3C5DA54C64605CF7BE84E13727F82 1e64e4e7582f99b3aec7caabda630ce75f9934f9d793dd0a75da44a5db1e9c62 e060f2ba-ac3a-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246753 CRP_kazalniki-v1.0.zip CRP_kazalniki-v1.0.zip CRP kazalniki v1.0 1 E8C286229FEA4FA3CE816EE12C6DDF7F 9c686bec945a6352efa6857b970ba4dd6bc84959d80e3d86c88451314e6ef2fd a2d6d0c7-ac28-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246640 aquacrop-slovenia.zip aquacrop-slovenia.zip Aquacrop Slovenia 1 1B65D2D7F187B384C246130D02E33BC4 804f25aeacaa5ae98a28abb71d372917058f16e27313563ac9b5b6d26e286ac7 bea629c0-ac2d-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246664 https://doi.org/10.5281/zenodo.22012153 Podatki in skripte 0 1a615c34-ac3b-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246759 Biotehniška fakulteta Sinteza Združevanje Simulacija Meritve in testi 0 0 0
