“…The answer is probably linked to the forest owner's risk perception. Indeed, to implement adaptation strategies, forest owners have to be convinced that climate change may be a threat to their forests (Sousa-Silva et al 2016). Some papers highlight the fact that forest owners' risk perception is a major issue when dealing with adaptation strategies (Blennow and Persson 2009;Blennow et al 2012;Yousefpour and Hanewinkel 2015).…”

“…) and nothing seems to be decided. Indeed, following Brukas et al (2001) the usual range for forestry project is [2%, 4%], following Calvet et al (1997) it may be higher for short rotation period, and it should be 4% following Snowdon and Harou (2014). After discussion with the forestry experts, we assume a 2% discount rate, and to analyze the robustness of our results to the variation of this parameter, we perform a sensitivity analysis (see Sect.…”

& Key message Reduction of forest rotation is analyzed as a potential adaptation strategy for a Douglas fir stand to cope with drought-induced risk of forest decline. The methodology combines a water balance modeling and an economic approach. Results show that, from an economic perspective, adaptation (immediate or delayed) is always better than the absence of adaptation. & Context Reduction of rotation length emerges as a potential adaptation strategy to cope with climate change. & Aim The study aims to address the reduction of rotation length to deal with the drought-induced risk of forest decline taking a multidisciplinary approach. & Methods We estimate probabilities and impacts of drought events quantified by water balance modeling and we evaluate, from an economic point of view, the reduction of rotation length to cope with the drought-induced risk of forest decline. We compare three different adaptation strategies at the economic level: absence of adaptation, immediate adaptation, and delayed adaptation. & Results Results suggest that immediate reduction of rotation length is associated with the best economic return, followed by delayed adaptation and, finally, by the absence of adaptation. This result is sensitive to the level of timber loss in the event of drought occurrence. If the loss of timber volume is higher than 48%, then delayed adaptation may be preferable to immediate adaptation. & Conclusion Beyond the specificities of the case study, this paper proposes a multidisciplinary approach to address adaptation strategies.

“…Nyilván ez az eredmény meglehetősen ország-specifikus, más helyszíneken eltérő eredmények adódtak (vö. Furness & Nelson 2012;Detten & Faber 2013;Sousa-Silva et al 2016) A módszertanban jelzett háromféle erdő-csoportosításban a válaszadók átlagos klíma-romlás-indexét a 2. ábra mutatja. Ez jelzi már azt, hogy a legnagyobb különbségek a regionális és az erdőtípus szerinti bontásban mutatkoztak, ezeket érdemes hát közelebbről is megvizsgálni, amikor az érzékelés és a hely kapcsolatát vizsgáljuk, hiszen a domborzati típusok kapcsán a hegyvidékekre és a síkvidé-kekre is számos esetben igaz, hogy valamelyest kisebb mértékben tapasztalják a problémá-kat.…”

KivonatTanulmányunkban országos kérdőíves mintán és interjúk segítségével vizsgáltuk az erdőgazdálkodók éghajlatváltozás-érzékelését és adaptációs tevékenységét. Eredményeink szerint leginkább a hótakarós napok számának csökkenését ér-zékelik a válaszadók, ám különbségek mutatkoztak az éghajlatváltozás érzékelésében a válaszadók földrajzi elhelyezkedése, és a kezelt erdőterületek jellege alapján. Szakirodalmi összevetésben elmondható, hogy a magyar erdésztársadalom a felkészülés szakaszában van, megvalósított adaptációról csak a válaszadók 16%-a számolt be, ugyanakkor többen jelezték, hogy ebben a jogszabályi előírások képeznek akadályt. A már alkalmazkodókról elmondható, hogy közöttük átlag-ban nagyobb fokú az aggódás, régebb óta érzékelik és jelentősebbnek tekintik a problémát, saját gazdálkodásuk eredmé-nyességét tekintve is. Megállapítottuk, hogy az állami erdőgazdaságok nem alkalmazkodnak jobban, s a magas fokú aggódásról sem mondható el, hogy blokkolná az éghajlatváltozáshoz történő alkalmazkodást, a természetvédelmi tényező pedig a kérdőíves adatok szerint ugyan nem hátráltatja az adaptációt, több interjúalany viszont erről számolt be.Kulcsszavak: éghajlatváltozás, erdészetek, érzékelés, adaptáció, Magyarország. CLIMATE CHANGE ATTITUDES AND ADAPTATION OF HUNGARIAN FOREST MANAGERS AbstractThis study utilizes a national questionnaire sample and interviews to examine attitudes to climate change as well as perceptions and adaptation activities among Hungarian forestry managers. The results show the respondents addressing climatic changes are concerned mostly by the decrease in the number of snow-covered days, but differences of opinion can be attributed to geographical location and the forest areas managed. Hungarian forest management is still in the preparation phase with only 16% of respondents reporting the implementation of climate change adaptation measures; however, many foresters claim this is often hindered by legislative constraints. Those who have implemented adaptation measures show an increased concern toward climate change on average; they have been aware of climate change for a longer time and regard it as a serious problem affecting their management activities. The study has evidence that state forest managers do not adapt better than private foresters do, high level of concern and nature conservation factors do not hinder adaptation. However, during the interviews respondents reported that nature conservation factors do, in fact, hinder adaptation processes.

“…Despite overwhelming evidence about climate change impacts on natural and human systems (Cramer et al 2014), uncertainty about impacts is often perceived as one of the main challenges for taking action on climate change (Moser and Ekstrom 2010, Hanger et al 2013, Yousefpour and Hanewinkel 2016. In forest management, a key problem is that actions to maintain ecosystem functions under a changing climate need to be taken several decades earlier than their expected effect (Spittlehouse andStewart 2003, Millar et al 2007). Yet, uncertainties related to future forest growth, the occurrence of disturbances, and mortality complicate taking decisions about the most suitable adaption and mitigation measures to implement (O'Hara and Ramage 2013, Petr et al 2016, Seidl et al 2017, e.g.…”

Background. Uncertainty about climate change impacts on forests can hinder mitigation and adaptation actions. Scientific enquiry typically involves assessments of uncertainties, yet different uncertainty components emerge in different studies. Consequently, inconsistent understanding of uncertainty among different climate impact studies (from the impact analysis to implementing solutions) can be an additional reason for delaying action. In this review we (a) expanded existing uncertainty assessment frameworks into one harmonised framework for characterizing uncertainty, (b) used this framework to identify and classify uncertainties in climate change impacts studies on forests, and (c) summarised the uncertainty assessment methods applied in those studies. Methods. We systematically reviewed climate change impact studies published between 1994 and 2016. We separated these studies into those generating information about climate change impacts on forests using models -'modelling studies', and those that used this information to design management actions-'decision-making studies'. We classified uncertainty across three dimensions: nature, level, and location, which can be further categorised into specific uncertainty types. Results. We found that different uncertainties prevail in modelling versus decision-making studies. Epistemic uncertainty is the most common nature of uncertainty covered by both types of studies, whereas ambiguity plays a pronounced role only in decision-making studies. Modelling studies equally investigate all levels of uncertainty, whereas decision-making studies mainly address scenario uncertainty and recognised ignorance. Finally, the main location of uncertainty for both modelling and decision-making studies is within the driving forces-representing, e.g. socioeconomic or policy changes. The most frequently used methods to assess uncertainty are expert elicitation, sensitivity and scenario analysis, but a full suite of methods exists that seems currently underutilized. Discussion & Synthesis. The misalignment of uncertainty types addressed by modelling and decision-making studies may complicate adaptation actions early in the implementation pathway. Furthermore, these differences can be a potential barrier for communicating research findings to decision-makers.
