“…This study was performed in the town of HeTian, southeast of ChangTing County, Fujian province, China (25°33′-25°48′ N, 116°18′-116°31′ E, 310 m above sea level), which experiences some of the most serious soil erosion in the Fujian province [38]. The main soil type is red soil, which is characterized as nutrient-poor with coarse grain granite parent material.…”

We investigated changes in leaf and branch stoichiometry of Pinus massoniana caused by seasonal variation and experimental drought in response to a three-year manipulation of the rainfall exclusion. The results showed that (1) in response to rainfall exclusion manipulation, plant capacity to regulate leaf potassium (K) concentrations were notably lower than for leaf nitrogen (N) and phosphorus (P) concentrations. Thus, the plants modulated leaf N and P concentrations to improve water use efficiency, which take part in drought resistance mechanisms. Leaf K concentrations decreased continuously, having additional indirect negative effects on plant fitness. (2) The effects of seasonal variation on both the leaf K and P concentrations were significantly stronger than on leaf N concentrations. High leaf N and P concentrations and a low N:P ratio in the growing season improved the growth rate. (3) Principal component analyses (PCA) revealed that to adapt to drought, the plants regulated nutrient elements and then maintained certain stoichiometries as a capital to resist stress. Our results suggest that, on nutrient-poor soils, a lack of N or P (or both) would probably impede P. massoniana’s response to drought.

“…through soil amelioration by roots and increased carbon input from litter fall). Vice versa, we test what the BP potential would be if BPs were to restore current land classified as degraded (Qin, Zhuang, Zhu, Cai, & Zhang, 2011;Xie et al, 2013). For this, we additionally use the Global Assessment of Human-Induced Soil Degradation (GLASOD, Fig.…”

“…On the other hand degraded areas were simulated to have been fully restored and then converted to BPs, which resulted in similar results compared to those of BPs on crop land alone, that is represent an optimal outcome. There are studies that claim that BP could indeed restore degraded soils (McElroy & Dawson, 1986;Xie et al, 2013) but others hold against that carbon emissions from land conversion and BP operation are high (Qin, Zhuang, & Cai, 2014;Qin et al, 2011).…”

Trade‐offs for food production, nature conservation and climate limit the terrestrial carbon dioxide removal potential

Large-scale biomass plantations (BPs) are a common factor in climate mitigation scenarios as they promise double benefits: extracting carbon from the atmosphere and providing a renewable energy source. However, their terrestrial carbon dioxide removal (tCDR) potentials depend on important factors such as land availability, efficiency of capturing biomass-derived carbon and the timing of operation. Land availability is restricted by the demands of future food production depending on yield increases and population growth, by requirements for nature conservation and, with respect to climate mitigation, avoiding unfavourable albedo changes. We integrate these factors in one spatially explicit biogeochemical simulation framework to explore the tCDR opportunity space on land available after these constraints are taken into account, starting either in 2020 or 2050, and lasting until 2100. We find that assumed future needs for nature protection and food production strongly limit tCDR potentials. BPs on abandoned crop and pasture areas (~1,300 Mha in scenarios of either 8.0 billion people and yield gap reductions of 25% until 2020 or 9.5 billion people and yield gap reductions of 50% until 2050) could, theoretically, sequester ~100 GtC in land carbon stocks and biomass harvest by 2100. However, this potential would be ~80% lower if only cropland was available or ~50% lower if albedo decreases were considered as a factor restricting land availability. Converting instead natural forest, shrubland or grassland into BPs could result in much larger tCDR potentials ̶ but at high environmental costs (e.g. biodiversity loss). The most promising avenue for effective tCDR seems to be improvement of efficient carbon utilization pathways, changes in dietary trends or the restoration of marginal lands for the implementation of tCDR.

“…Soil erosion was not only distributed in arid and semiarid regions, but also prevailed in humid subtropical China. Excessive extraction of natural resources, such as over-logging, grazing and farming, was widely claimed as the primary cause of severe soil erosion in red soil regions of southern China during the past six decades (Wang et al, 2011;Xie et al, 2013). In these areas, soil erosion has plagued livelihoods and rural sustainability for a long time.…”

“…In red soil regions of southern China, the methods such as closing hillsides for afforestation, planting trees and grass, forest fertilizing and planting fruit trees have been proven to be successful and have been widely utilized to restore degraded ecosystems since the last decade (Yue & Chen, 2003;Li et al, 2008;Gao et al, 2011;Zhong et al, 2013). However, the criteria of the evaluation were mainly based on ecological benefits measured by ecological indices (such as vegetation coverage, soil loss, biomass and productivity, soil nutrients and vegetation species) (Jiang et al, 2009;Xie et al, 2013). The method, having the largest environmental benefits, was considered the best (Yue & Chen, 2003;Li et al, 2008;Jiang et al, 2009).…”

Cost‐Effective Targeting Soil and Water Conservation: A Case Study of Changting County in Southeast China

Soil erosion is by far the greatest cause of land degradation and other environmental and socio-economic problems in China. Although various conservation methods are widely utilized to reduce soil erosion and to sustain agricultural production, the cost-effectiveness and selection of these methods are less known. Using our survey and ecological data, this study evaluated four soil and water conservation methods in Changting County, Southeast China. The results show that the disparity of conservation costs is much larger than that of ecological benefits. Planting fruit trees is a kind of conservation through primarily economic development. Closing hillsides for afforestation is most costeffective, followed by forest fertilizing, and planting trees and grass. Our findings suggest that comparatively lower cost conservation methods, for example closing hillsides for afforestation, should be considered in priority if initial ecological conditions can meet the requirements of the method.
