20.500.12556/RUL-170869 Kmetijstvo znotraj planetarnih meja, izzivi in priložnosti Food production within planetary boundries, challenges and opportunities Zadnjih 10.000 let, v geološki dobi holocena, so bile razmere na Zemlji izredno stabilne, s temperaturnimi nihanji le za dobro stopinjo. Te razmere so ohranjali zemeljski sistemi in njihove medsebojne interakcije, večino preko negativnih povratnih zank. Trenutno se nahajamo v novem geološkem obdobju, antropocenu. Glavno gonilo sprememb, ki so povzročile novo stanje na Zemlji, so človeške aktivnosti. Od 50ih let prejšnjega stoletja dalje se je začela eksponentna obremenitev vseh naravnih virov, obdobje, imenovano Veliki pospešek. Zaradi velikih pritiskov na zemeljske sisteme obstaja nevarnost prekoračitve prelomnih točk in planetarnih meja. Planetarne meje so prve znanstveno določene vrednosti, znotraj katerih ni visokega tveganja za doseganje prelomnih točk. Trenutno smo presegli šest od devetih planetarnih meja. Kmetijstvo vliva na prekoračitve petih od devetih planetarnih meja: raba sladke vode, sprememba rabe tal, biogeokemični cikli fosforja in dušika, celovitost biosfere in podnebne spremembe. Za stabilizacijo podnebja so potrebne sistemske spremembe in prehod na bolj trajnostni prehranski sistem, ki bo imel minimalni vpliv na okolje ali pa celo prispeval k blaženju podnebnih sprememb. Tako na globalni, evropski kot državni ravni imamo trenutno več politično zastavljenih zavezujočih ciljev za zmanjšanje negativnih vplivov kmetijstva. Zastavljene cilje lahko dosežemo preko sprememb v kmetijskih praksah in prehranskih navadah ter preko bolj trajnostnega ravnanja s hrano. The past 10.000 years, during the geological epoch known as the Holocene, natural conditions on Earth were more stable than ever before in the geological history of the Earth, with average temperatures fluctuating for just over one degree Celsius. These stable conditions were maintained through numerous Earth systems and their interactions through feedback loops. We are currently living in a new geological epoch, called the Anthropocene. Human activities are the main driver of changes that have caused the shift towards these new conditions on Earth. Since the 1950s, there has been an exponential increase in the exploitation of natural resources, a period known as the Great Acceleration. Due to the increasing pressures on Earth's systems, there is a risk of crossing critical tipping points and planetary boundaries. Planetary boundaries are the first scientifically defined thresholds within which the risk of crossing critical tipping points remains low. Currently, six out of nine planetary boundaries have already been exceeded. Agriculture is the primary driver of the transgression of five out of nine planetary boundaries (freshwater use, land-use change, biogeochemical flows of phosphorus and nitrogen, biosphere integrity and climate change). To stabilize the climate, a transition to a more sustainable food production system is necessary. At global, European and national levels, multiple politically binding targets have already been established to halt the negative impacts of agriculture. These targets can be achieved through systemic changes in farming practices as well as through shifts in dietary habits and more sustainable food management. planetarne meje kmetijstvo zemeljski sistemi podnebne spremembe planetary boundaries agriculture Earth systems climate change true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-07-19 07:15:56 2025-07-19 07:16:04 2025-07-22 09:45:37 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 257856 243319043 49444.pdf 49444.pdf 1 E9DA395258F104B8A01741FC6E8F2EBC a3049e23183cb1873e539a8b97a659c324579b4cce420ed50bff65764f7f73d9 766e7f21-645f-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=213138 Biotehniška fakulteta 0 0 0
