A review of the current status of air pollution and climate change (CC) in the United States from a perspective of their impacts on forest ecosystems is provided. Ambient ozone (O3) and nitrogen (N) deposition have important and widespread ecological impacts in U.S. forests. Effects of sulphurous (S) air pollutants and other trace pollutants have significant ecological importance only at much smaller geographic scales. Complex interactive effects of air pollution and CC for selected future CC scenarios are reviewed. In addition, simulations of past, present, and future hydrologic, nutrient, and growth changes caused by interactive effects of air pollution and CC are described for two U.S. forest ecosystems. Impacts of O3, N deposition, and CC on growth and hydrology of mixed conifer forests in the San Bernardino Mountains in southern California were projected with the DayCent model. Effects of N deposition, CO2 fertilization, N deposition, and CC on northern hardwood forests at the Hubbard Brook Experimental Forest in New Hampshire were simulated with the PnET-BGC model. Projected changes in these forests can influence the provision of ecosystem services such as C sequestration and water supply. The extent of these effects will vary depending on the future intensity and extent of CC, air pollutant emission levels, the distribution of air pollution, and other factors such as drought, pest outbreaks, fire, etc. Our chapter ends with research and management recommendations intended to increase our ability to cope with uncertainties related to the future interactive effects of multiple air pollutants, atmospheric deposition, CC, and other biotic and abiotic stressors.

Forests provide many supporting, regulating and cultural services. Extensive environmental changes have resulted in a substantial loss or degradation of forest ecosystem services (ES). Unclear interactions of climate-change phenomena make it difficult to estimate forest ES. Research on interactive effects of climate change and air pollution has become a central issue in forest science during the past decade. Climate change in interaction with air pollution brings novel combinations of severity and timing of multiple stresses, which may significantly affect many forest ES. The aims of the present chapter are to identify basic concepts of evaluating ES with a focus on forest ES, to provide physiological and ecological bases for their evaluation, and to discuss the interactive effects of climate change and air pollution on forest ES based on selected tree physiological functions. Climate regulation mediated by deforestation-induced changes in the hydrological cycle is discussed. Adaptive governance and communication to the public promotes sustainable forest–multi-stakeholder collaboration. A case study is presented evaluating selected ES in a forest–agricultural landscape in the Czech Republic on the basis of monitored energy, water and material flows estimation. From this study, it is apparent that future research must include multi-factorial anthropogenic and natural interactions of climatic changes and air pollution in conjunction with sustainable forest ES provisions. Sustainable forest management is an essential tool for reducing the vulnerability of forests to environmental change.

We analyse options to adapt forest and agricultural ecosystems to the adverse consequences of climatic change. We provide an overview of global change as it relates to the forest and agriculture sectors and conclude that forests should be analysed and their management optimised, together with their neighbouring agricultural ecosystems, if we are to be successful in meeting the challenges of future land-use conflicts. These challenges include balancing the need to satisfy increasing food and resource demands (provisioning services) while still providing indispensable regulating services such as climate and water protection. For the forestry sector, we identify various options to adapt ecosystems to climatic change, such as appropriate choice of tree species, mixed and uneven-aged forests, thinnings and adapted rotation length. We see, however, great potential in comprehensive land-use portfolios containing mixed, and thus diversified, alternatives—with patches of croplands, pastures and forests—to achieve a more sustainable intensification of land-use concepts. Such concepts would reduce the vulnerability of land-use systems to the effects of climatic change. Natural forests, whose continued existence must be secured by conservation payments, are a necessary component used to store carbon, to protect the water balance and to preserve biodiversity. In future, comprehensive land-use models are necessary to make demonstrable and to optimise the ecological and economic consequences of various land-use concepts.

Untangling the complex effects that different air pollution and climate change factors cause to forest ecosystems is challenging. Supersites, that is, comprehensive measurement sites where research and monitoring of the whole soil–plant–atmosphere system can be carried out, are suggested as a refinement of the current monitoring and research efforts in Europe. This chapter identifies and discusses key measurements to be carried out at such supersites, with a focus on four topical subjects: the carbon, nitrogen, ozone and water budgets. This kind of holistic approach is vital to a realistic translation of the ongoing changes in climate and air quality into research on the impacts on forest ecosystems. Such an integrated effort requires a considerable use of resources at highly instrumented measurement sites and can only be achieved by building on existing infrastructures.

Contemporary societies expect a range of services (including of carbon sequestration) to be supplied from forest ecosystems. Their growing societal importance is clearly reflected in policies. The conceptual framework for the states that people are integral parts of ecosystems and that a dynamic interaction exists between them and other parts of ecosystems. This approach encompasses social, economic and environmental interactions, and the dynamics and cross scale issues that have multiple outcomes. However, forest multifunctionality is a challenge since the combination of multiple ecosystem services may be very different and dependent on a high number of factors. Stakeholder priorities with respect to individual ecosystem services may be variable, as may be a range of stakeholders. Reflexive, participatory and multilevel governance, in a continuous process of its adjustment, needs therefore to be developed to enable forestry decision-makers to consider existing opinions and behavioural patterns of the diverse stakeholders who drive the forestry change and respond to it. In such a retrospective, numerous questions have arisen, among which the integration of carbon sequestration into multifunctional forestry is among priorities. Carbon forestry enables society to buy time for development of low carbon and decarbonisation technologies; while its integration into multifunctional land use offers innovation, employment and new markets, with locally and regionally oriented value chains. This particularly concerns remote areas where forestry could foster socio-economic development and combine it with the enhancement of nature and rural landscape. However, the question: how to multiply synergies and balance trade-offs merits attention. Fostering resilience of forestry systems to climate change necessitates the establishment of an appropriate framework, because, although multipurpose afforestation may result in lower rates of carbon sequestration, it is expected to be more attractive to people as it will provide additional benefits and will promote sustainable development.

Goods and services provided by forests will be needed in greater amounts in the coming decades, yet are threatened by climate change and air pollution. In this chapter, we survey the peer-reviewed literature on elevated atmospheric CO2 (eCO2) and tropospheric O3 (eO3) interaction experiments, and discuss implications of results for policy development and social welfare. We located 58 studies reporting data on physiology, biomass production, litter quality and decomposition. Studies were abundant for young and intermediate ages, but non-existent for mature forests. Most plant parameters increased with exposure to eCO2, decreased under eO3 and were often intermediate for the eCO2×eO3 interaction, though this latter treatment was not always statistically significant. Current environmental policy could make better use of existing science, but more work, especially on mature forest ecosystems, is needed in step with process-model development to better predict forest responses and guide policy for future changes in air quality and climate.

Climate change is expected to affect the exchange of gases between forest ecosystems and the atmosphere. In this review, we focus on a few related topics, including the emission of greenhouse gases from the forest floor, and vegetation fires and their impact on air quality and soil CO2 efflux. In particular, we summarise the current state of knowledge on O3 deposition in forest ecosystems, both for stomatal uptake and non-stomatal sinks. Based on such summaries, we discuss interactions between forests, atmospheric composition and climate, and finally outline directions for multi- and interdisciplinary research required for mechanistically understanding such interrelationships.
