Overview

In this paper, the pathway from peat resources to their various forms of utilization, to their environmental impacts, and to their mitigation is discussed. Overall, research gaps related to various fields of peat studies are identified and recommendations for future research are presented. Global peat reserves are large, but they remain mostly unused. Peat can also be valorized in various less GHG–intensive applications beyond combustion. Heterogenocity of peat may constraint many of these uses, warranting new innovations to support their feasibility. The theme of GHG emissions from peatlands is complex. The future of northern peatlands as carbon sinks remains uncertain. Paludiculture, an emerging research field, and its GHG mitigation potential is also discussed. When discussing peat production, one of its main adverse effects typically disclosed is its impact on the water quality of natural aquatic systems. Thus, different traditional and novel peat bog drainage water treatment methods are extensively compared with each other — a topic not previously presented in the literature. Peatland restoration and its novel applications, as well as economic aspects, are also addressed. Socioeconomic aspects of peat use, closely linked to climate, food, and rural livelihoods, are currently under vigorous research, and are also examined.
