“…Notorious among the factors of change was the construction of the Xiaolangdi Reservoir, which intercepts streamflow and has reduced the water and sediment discharging into the YRD (Wei et al 2016). The resulting modifications to the YRD include changes to its morphology, biodiversity, wetland landscape, and vegetation dynamics (Jiang et al 2013, Kong et al 2015, Hua et al 2016.…”

The Yellow River Delta (YRD) has been experiencing substantial climatic, hydrological, and anthropogenic stresses, and a sound understanding of the regime shift in its hydroclimate-vegetation system is of fundamental importance for maintaining the health and stability of its regional ecosystems. This study constructs and analyzes a 34-year-dataset (1982-2015) of hydro-climatic variables and satellite-based Normalized Difference Vegetation Index (NDVI) in the YRD. A seasonaltrend decomposition technique based on loess (STL), and a structural change analysis were coupled to detect regime shifts of regional hydroclimate and vegetation in the YRD from 1982 through to 2015. During this period the YRD exhibited a significant warmer-drier-greening trend and experienced four regime shifts of its hydroclimate-vegetation system, with the four shift periods roughly centered in 1989, 1998, 2004, and 2012. Partial correlation analysis revealed that temperature was the dominant factor promoting vegetative growth in spring and autumn (all P NDVI-TEM greater than 0.65), and streamflow impacted the NDVI mainly in summer. Temperature and precipitation were the dominant controls of vegetative growth during the growing season prior to 2002, and thereafter precipitation and streamflow alternately became the main moisture-influencing factors of vegetative growth. Streamflow played an important complementary role on vegetative growth, particularly in near riverine areas when drought exceeds a certain threshold. Additionally, climate shifts determined the changing trend of NDVI across the region, while the effect of land use change is localized and predominant in the northeastern part of the study region. These findings offer an insight into appropriate water regulation of the Yellow River and on climatic adaptation within the YRD.

“…The setting of restoration goals can be driven by the scale, social context, and projected levels of recovery (Hull et al, ; Ren, Lü, Fu, & Zhang, ). Prospecting suitable areas for restoration is important for executing efficient restoration projects and maintaining the health of the ecosystem (Hua, Cui, He, & Cai, ). With regard to scale, successful restoration of a community depends on both regional and local factors (Palmer, Ambrose, & LeRoy, ).…”

Successes and failures reported in a multiscaled framework constituted by biophilic projects engineered toward environmental recovery

The process of landscapes' fragmentation has led to having two realistic complementary options: (a) developing techniques and approaches for conserving the healthy remaining forest fragments and (b) restoring degraded places. The second option can be conducted by projects that focus on restoring or rehabilitating the degraded environment. In this research, a framework was tested through a set of pilot-scale projects in a highly urbanized Municipality of the southeastern Brazilian region (Sorocaba, São Paulo State). Four projects were carried out in order to test the efficacy of techniques devoted to solving different problems of environmental degradation (isolation of fragments, loss of biodiversity, soil erosion, and bioinvasion) in different environments (terrestrial [forested and nonforested] and aquatic [rivers]) through the acceleration and orientation of the process of restoration. Here, we show the main findings, discuss the potential and weaknesses found in each project, and offer some recommendations for future potential users. The projects are constituted of techniques and approaches that are all cheap, naturally based, and easy to be implemented and with a high probability of social comprehension and acceptance. In each project, we got interesting outcomes, considering all successes and limitations (for example, a high reappearance of vegetation in streams and strong control of soil erosion). This model embraces the main aspects of environmental recovering through a feasible, realistic, and socioecological approach, and it brings high potential to be used by other researchers and also for technicians and decision makers who search for feasible and realistic projects.

“…Hence, there is an urgent need to rehabilitate or restore degraded wetlands. Subsequently, an assortment of restoration efforts have been developed to restore degraded wetlands, such as hydrology restoration, ecosystem maintenance, seed bank restoration, and habitat replacement and compensation . Little information is available on the optimal reforestation vegetation patterns to rehabilitate or restore degraded wetlands, especially on the selection of a reasonable planting density.…”

To understand the effects of planting patterns on trace metal fractions in degraded wetland soils in the Jinjiang Estuary, the chemical speciation of trace metals (Cu, Cr, Zn, and Pb) before and after wetland restoration is analyzed based on a measurement and testing program. The results show that wetland restoration, in general, increases the ratios of Cu, Cr, Zn, and Pb in the acid‐soluble fraction and the ratios of Cr, Zn, and Pb in the residual fraction and decreases the ratios of Cr, Zn, and Pb in the reducible fraction and the ratios of Cu, Cr, Zn, and Pb in the oxidizable fraction; thus, the mobility of Cu increases, and the mobility of Cr, Zn, and Pb decreases. Moreover, the planting patterns influence the levels of Cu, Cr, Zn, and Pb to some extent. After wetland restoration, the levels of Cu show an upward trend, and the Pb levels exhibit a downward trend. However, the potential ecological risk of Cu, Cr, Zn, and Pb fail to decrease. The restoration time may have been too short. The results of this study indicate that the planting patterns influence the transformation of trace metal fractions in soil and affect the pollution degree and potential ecological risk, contributing to a better understanding of the effects of planting patterns on trace metals following wetland restoration. The results will be helpful for subsequent scientific research on wetland restoration.
