“…This provided major variable sources for the model. Other studies [8,36,46,52,[59][60][61][62][63][64][65] supplied important information for variable selection and pathway determination. When data were unavailable, proxy datasets were identified.…”

“…These incentives will decrease the maintenance of groundwater levels to the required depth at salinization threatened areas; at the fertile areas, salt accumulation will be induced on the surface due to the lack of water for soil salt leaching and drip irrigation will threaten the fertile land [65,91]. Therefore, implementation of drip irrigation requires very strict salt leaching practices regularly.…”

Significant anthropogenic and biophysical changes have caused fluctuations in the soil salinization area of the Keriya Oasis in China. The Driver-Pressure-State-Impact-Response (DPSIR) sustainability framework and Bayesian networks (BNs) were used to integrate information from anthropogenic and natural systems to model the trend of secondary soil salinization. The developed model predicted that light salinization (vegetation coverage of around 15-20%, soil salt 5-10 g/kg) of the ecotone will increase in the near term but decelerate slightly in the future, and that farmland salinization will decrease in the near term. This trend is expected to accelerate in the future. Both trends are attributed to decreased water logging, increased groundwater exploitation, and decreased ratio of evaporation/precipitation. In contrast, severe salinization (vegetation coverage of around 2%, soil salt ≥20 g/kg) of the ecotone will increase in the near term. This trend will accelerate in the future because decreased river flow will reduce the flushing of severely salinized soil crust. Anthropogenic factors have negative impacts and natural causes have positive impacts on light salinization of ecotones. In situations involving severe farmland salinization, anthropogenic factors have persistent negative impacts.

Post-bog soils developed from limnic calcareous sediments are closely related to a young-glacial landscape and postglacial lakes in Northern Poland. The studies conducted in 2010-2012 on post-bog soils near lake Dubie (Równina Drawska, NW Poland), partially used as an arable land. The goal of research was to characterise some chemical and physical properties of post-bog soils developed from carbonate deposits near lake Dubie. The soils of the analysed area developed from lacustrine chalk and calcareous gyttja belong to black earth and mucky soils. Organic matter content in surface horizons ranged from 5.0 to14.2%, content of CaCO 3 from 27.2 to 55.2%, the highest carbonate content was found in arable soil. The soils of the study area were characterised by a narrow C/N ratio, low level of total form of P and a high content of Ca. Specific density of surface horizons was in the range 2.49 to 2.58 Mg⋅m -3 , bulk density from 0.445 to 1.212 Mg⋅m -3 . High porosity was also found in the examined formations, from 0.826 in surface horizons and 0.700 m 3 ⋅m -3 in limnic deposits.

“…Baiyangdian Lake is the largest freshwater lake in northern China supporting people's livelihoods with an array of services, such as fisheries, reed production, water for drinking and irrigation, and local climate regulation. In the past 40 years, lake area in Baiyangdian decreased in half from reduced inflows, increased drought frequency, and increased sedimentation because of climate change, upstream dams, and irrigation (Liu et al 2006). Reduced inflow and increased discharge of pollutants have reduced lake water quality from Grade III to Grade V (ADB 2008).…”

Advancing Wetland Policies Using Ecosystem Services – China’s Way Out

China's wetlands provide valuable services to society, which are necessary for sustainable development. The Chinese government considers wetland protection a national priority, and is making progress on the ambitious goal of protecting more than 90 % of its natural wetlands by 2030. Despite the rapid growth in conservation actions, wetlands remain threatened because government, industry, and the public are using wetlands unsustainably, and there exists weak enforcement of wetland protection laws. Chinese policymakers in part are trying to use the ecosystem services approach to incentivize conservation to reduce wetland losses across spatial scales (local, regional, and national). However China currently lacks a systematic, scientific process for monitoring wetland ecosystem services, so scientists and managers can establish and refine ecological compensation schemes. In this paper we present a scientific framework on monitoring wetland ecosystem services aimed at improving national wetland policies in China. First we review the current status of China's wetlands and its wetland policies. In particular we present the growing popularity of ecological compensation in China, which is driving the demand for ways to measure and value ecosystem services in China. Next we outline the major challenges threatening wetland protection and the science policy needs on wetland ecosystem services. Lastly we present a scientific framework on monitoring wetland ecosystem services aimed at helping meet China's growing policy demands on ecosystem services.
