“…Paradis et al ). Because most activities in peatlands usually involve compression or removal of the peat profile, there is often a sharp eco‐hydrological disconnect between (1) the residual old peat layers and the newly formed moss carpet (McCarter & Price ) and (2) the edge of the natural peatland and the ecotone of the restored site (Paradis & Rochefort ). Research is needed to improve the eco‐hydrological connectivity of restored peatlands.…”

Peatland restoration in North America (NA) was initiated approximately 25 years ago on peat‐extracted bogs. Recent advances in peatland restoration in NA have expanded the original concepts and methodology. Restoration efforts in NA now include restoring peatlands from many diverse types of disturbances (e.g. roads, agriculture, grazing, erosion, forestry, and petrol industry infrastructure impacts) and occur in a greater array of peatland types (e.g. fens and swamps). Because fens are groundwater and surface flow driven, techniques to restore the hydrology of fens are generally more complicated than bogs. Restoring a greater variety of peatland types on a large‐scale basis (>10 ha) commands new techniques for reestablishing a broader array of plants other than Sphagnum spp., including non‐Sphagnum mosses, sedges, nonericaceous shrubs, and trees. The rationale for restoring peatlands has expanded to include legal requirements, wetland mitigation and banking, climate mitigation, water quality, and as part of responsible ecosystem management for industry or society. In the past 25 years, peatland restoration in NA has evolved from (1) trial and error to a more empirically based scientific approach, (2) small site‐specific experiments to landscape‐scale restoration (e.g. hydrological connectivity, ecological fragmentation), and (3) individual stakeholder (academic) to multiple stakeholders across jurisdictional boundaries (private, local, and regional governmental agencies, NGOs, and so on). However, many research gaps still exist that must be addressed to enhance our ability to restore peatlands successfully.

Ecological Risks Arising from the Impact of Large-scale Afforestation on the Regional Water Supply Balance in Southwest China

Ecological degradation impedes sustainable development in Southwest China, and artificial afforestation has been a key strategy of the Government of China to effectively curb it. However, the water consumed by large-scale afforestation has a huge impact on water supply in Southwest China, which also arise a new challenge causing severe drought here recently. In order to determine the impact of artificial afforestation on the region, this study conducts spatiotemporal, abrupt change, and correlation and regression analyses. Results show that although water resources fluctuate, they exhibit a general declining trend. Especially after 2000, water resources showed a significant downward trend. In terms of spatial tendency, there has been an obvious decrease in water resources in the Sichuan Basin, the mountainous region of eastern Chongqing, and the Yunnan-Guizhou Plateau. Due to extensive afforestation and vegetation cover growth, there has been an increase in most trends of forest-shrub ecosystems, resulting in substantially enhanced evapotranspiration effects. The uptake of water by afforestation in Southwest China could reach 40.42 billion m 3 , which is equivalent to 10.69% of its annul available water supply (1980-2015). Generally, afforestation disrupts the water balance of the region. This study recommends substituting afforestation for natural restoration or, at the very least, selecting vegetation that requires less water for the restoration of the ecological environment of Southwest China, which provide scientific method for regional sustainable development. The IPCC Fifth Assessment Report on climate change stated that global surface temperatures rose by 0.85 °C from 1880 to 2012 (from 0.65 °C to 1.06 °C, respectively). Global warming leads to frequent extreme weather and climate events and impacts both the water supply and the ecological environments of numerous countries 1,2. Severe droughts are caused by a decrease in precipitation, which leads to shortages in water supplies, and such droughts are harmful to life, production, and ecology. Moreover, events such as these have dual attributes, that is, natural attributes and social attributes. This is an important factor which restricts the sustainable development of societies 3. Since the twenty-first century, drought events in Southwest China have moved into a period of "high incidence". With increases in interannual and annual variation in rainfall in Southwest China, the frequency of droughts have increased, and years of serious and catastrophic drought events in different regions and during different seasons have subsequently increased 4. Thus, strengthening research on drought characteristics and causes in Southwest China as well as the level of response, providing a scientific basis for decisions on disaster prevention and mitigation, have important practical implications 5,6. Since 2010, there have been many serious drought events reported in Southwest China, including Yunnan, Guizhou, and Sichuan provinces and the municipality of Chongqing, which...
