    In light of the increased focus on climate change adaptation, there is a need to understand when and how adaptation decision-making generates trade-offs. This study presents a novel framework for adaptation trade-off assessments, which integrates (I) two trade-off mechanisms (direct and interactions) and (II) two types of trade-off characteristics (substantive and processual). Perspectives on adaptation trade-offs were collected from 37 Swedish and Finnish agricultural experts through semi-structured interviews supported by serious gaming and visualization. The data were thematically analysed based on the provided analytical framework. The results show that trade-offs in agricultural adaptation decision-making processes involve balancing a number of socio-ecological system aspects that are of different character and have different functions. The study identified 20 aspects generating trade-offs related to adaptation management in Swedish and Finnish agriculture, among which 'crop yield and profitability', 'farm economy', 'pest and weed robustness' and 'soil quality' were discussed as the most prominent by respondents. The framework enables an examination of complex trade-off structures that can have implications for adaptation management decisions. The results show that the identified aspects constitute different components and functions of trade-offs, including both processual and/or substantive ones. In conclusion, the 20 identified aspects and the framework together demonstrate the importance of the two types of adaptation trade-offs and the resulting complexity of climate change adaptation decision-making in Swedish and Finnish agriculture. Furthermore, the study asserts the potential of applying the framework for various strategic contexts-to recognize and cope with trade-offs in adaptation management.

    Lake Sakylan Pyhajarvi has been an important fishing site and drinking water source for the local population for centuries. The lake has undergone significant changes: (1) the water level was lowered in the 1600s and in the 1850s; (2) planktivorous coregonid fish were successfully introduced in the early 1900s; (3) nutrient input from intensified agriculture has increased since the 1950s and (4) the effects of the current variable climate on the lake and its catchment have become more evident since the 1990s. We determined the phases of oligotrophication, eutrophication and recovery and elucidated the ecosystem changes by combining palaeolimnological records with detailed neolimnological data. The sedimentary diatom and cladoceran assemblages first showed a relatively eutrophic period followed by oligotrophic periods, linked with the artificial changes in water level and consequent shifts in macrophyte abundance. The oligotrophic period in the early 1900s is thought to represent the target trophic state for the lake. After the 1950s, introduction of vendace resulted in higher planktivory reflected by an increased relative abundance of small-bodied pelagic cladocerans. Signs of eutrophication occurred due to increased nutrient load. During the last 10 years, signs of recovery have been recorded. A complex history such as that of Lake Pyhajarvi illustrates the difficulties in selecting management targets, and the risk of setting false targets, for lakes based solely on monitoring data-both neolimnological and palaeolimnological approach are needed.

    Climatic changes are expected to pose challenges to Nordic agriculture. While some changes may provide opportunities for higher productivity, others may severely increase agricultural vulnerability. Farmers attempt to adapt or cope with these changes by taking measures to decrease vulnerability or to take advantage of potential benefits, but little is known what outcomes these adaptation measures might have. This study identifies unintended negative impacts of adaptation measures, drawing on a literature review and interviews with farmers and agricultural officials and experts in Sweden and Finland. Based on the conceptual framework of maladaptation, this study identifies outcomes that either increase the vulnerability of the implementing actor, shift the vulnerability to other actors or sectors or affect common pool resources. While a large number of adaptation measures rebound vulnerability to the implementing actor, several potential maladaptive outcomes may shift vulnerability or affect common pool resources. The findings point to the large number of trade-offs that are involved in adaptation decision-making and lead to the conclusion that raising awareness of these aspects can support future adaptation strategies.

    Extreme weather events, such as storms, may cause material damage, injuries, and interfere with day-to-day operation of societies. Earlier research on natural hazards and climate change adaptation has found that demographic and socioeconomic factors influence the way individuals prepare for and are affected by natural hazards. However, research often focuses on areas with high exposure and vulnerability and research on low exposure and vulnerability areas is scarcer. To address this gap, we ask: do socioeconomic and demographic factors matter in how individuals prepare for and are affected by storms in Finland? Our data consist of an internet survey (n = 1014) conducted after a severe winter storm hit Finland in the beginning of 2019, and we analyze the data with Chi-squared tests and logistic regressions. Our results show that respondents? education level or employment status are not connected to whether they took preparedness measures or whether they experienced harm. Instead, the type of residential property does play a part. In addition, respondents who had experienced storm-related harm during recent years are more likely to prepare than those who have not. In conclusion, socio-demographic factors seem to have only marginal influence on storm preparedness or experienced impacts in Finland, which contradicts earlier research. This may stem from the relatively equal distribution of well-being among the population.

    Expectations of cooperation between local authorities, the private sector, and citizens in climate change adaptation in cities are high because involvement of many actors is seen as critical to success. Scholars and policymakers argue that the private sector could be more efficient than the public authorities in implementing adaptation measures and argue for the need to engage citizens to ensure legitimacy of adaptation and inclusion of locally relevant knowledge. To what extent do cities address the private sector and citizens in their adaptation initiatives? What modes of governance do they use to do this? What kinds of cities are the most likely to address the private sector and citizens? Going beyond the existing case study approaches, this paper answers these questions using a large N data set covering 402 cities around the world. We find that a majority of adaptation initiatives focus exclusively on the public sector and do not address the private sector or citizens. In the cases where they do, the private sector is more often governed through partnerships and participation, whereas citizen participation is relatively rare. Initiatives involving citizens rely more often on a provision of information that encourages citizens to adapt. We find that the more advanced a city is in its adaptation process, the more likely it is to address the private sector than citizens in its initiatives to adapt to climate change. Whereas with partnerships and participation the private sector can influence urban adaptation arrangements at a broader scale, the provision of information allows citizens only to implement individual adaptation measures according to their capacities.

    Cities have increasingly recognised the risks posed by climate change and the need to adapt. To support climate action, cities have formed cooperative networks such as the C40 Cities Climate Leadership Group, the Global Covenant of Mayors and the International Council for Local Environmental Initiatives. However, a lack of scientific evidence exists when it comes to the actual impact of network participation, especially in the context of adaptation. This study is the first to test statistically the association between network membership and progress in adaptation planning in 377 cities globally. The results show that network members are more likely to have started the adaptation process than other cities, and that being a member of multiple networks is associated with higher levels of adaptation planning. Moreover, cities in wealthier countries are more likely to be more advanced in adaptation planning than others. We consider the possible explanations for these results based on the previous literature and information gathered from the networks. The main implications of our study are that network organisations should consider how to encourage the adaptation process among their members and the increased involvement of cities from lower-income countries.
