Abstract： Asian Water Tower (AWT) provides population in High Asia and broader areas in downstream with critical water resource, creating significant socioeconomic values. It is also unreplaceable in regional economic development in central and south Asia. Moreover, the associated region is an example of regional development to share the common future in Road and Belt Initiatives. This article shed a light on and provides various examples about AWT’s socioeconomic effects in High Asia Region. Not only does it support the regional development, but also the competition for AWT’s water resources due to its increasing scarcity in dryland would potentially bring in conflicts. That would become even more uncertain and challenging when the deterioration of AWT is considered as a result of climate change. It would then fundamentally change the future development in High Asia Region. Therefore, it is urgent to respond and adapt to the change by developing sustainable pathways. This article further address the Sustainable Development Goals (SDGs) that are most concerned by the countries in High Asia Region, and illustrate the relations of the cryosphere services of AWT to the implementation of SDGs.

Abstract： The cryosphere is closely related to human society. As a result of climate warming and corresponding cryosphere shrinkage, the cryosphere functions (CFs) and their associated services and hazards are undergoing profound changes. On the one hand, the cryosphere hazards become more and more frequent with heavily extreme events; on the other hand, the overall cryospheric service (CS) capacity has been deteriorating and would continue or be eventually lost. This article introduced the concepts of CFs, CSs, and their value on the basis of summarizing the human and social characteristics of the cryosphere and its affected areas. Then, taking the importance of world’s “water towers” and changes in polar systems as examples, we illustrated the changes in CSs and their impact. Finally, the resilient pathway of cryosphere-affected socio-ecological systems was further discussed.

Abstract： Public awareness of environmental issues and engagement in environmental protection has been greatly improved with the rapid economic development. As a result, the deployment of projects with potential impacts on environment and human societies faces substantial challenge from the public. To ensure the success of such projects, receiving only government approval and meeting legal and regulation requirements is no longer enough. Public acceptance becomes essential, that is to acquire a social licence to operate (SLO). Projects without the SLO can be faced with great risks and financial loss. Although having gained widespread attention in mining, chemical industries and other related fields, the concept of SLO has gained attention from psychologists quite recently. The present article reviews the origin and measurement of the concept of SLO, as well as the approaches to obtain and maintain a SLO. We further highlight the fundamental drivers of SLO and the implications for policy makers. Future directions are discussed to address the challenges regarding the measurement and acquisition of SLO.

Abstract： Focused on the partly issue that in the process of single-frame image super-resolution reconstruction, such as insufficient utilization of feature information during image super-resolution reconstruction, the interdependence between the channels of the feature map is difficult to determine, and reconstruction errors existing at high-resolution image reconstructed, this paper proposed an single image super resolution methods based on depth residual backprojection attention network. It used the residual learning to ease the training difficulty and fully discover the feature information of the image, and used the back-projection method to learn the interdependence between the high- and low-resolution images. In addition, it introduced the attention mechanism to assign each feature map with different attention to discover more high-frequency information, and learnt the interdependence between the channels of the feature map. The experimental results show that compared with most single-frame image super-resolution methods, the proposed method not only has a significant improvement in objective indicators, but also the reconstructed predicted image has richer texture information.

Abstract： Positive-semidefinite constrained metric learning (PCML) , as a typical metric learning method combined with support vector machine (SVM) , exhibits superior performance in image recognition and person re-identification. However, in the process of learning the metric matrix, this method simply considers the margin between samples of different categories, ignoring that the feature space of samples of the same category also changes. To this end, this paper proposes a metric learning method based on the intrinsic structural characteristics of data. First of all, compared with PCML, the method not only considers the margin between samples of different categories, but also considers the intra-class divergence matrix of samples of the same category, so that the learned metric matrix has stronger discrimination ability. Secondly, this paper further transforms the L1-norm loss function into the L2-norm loss function, which can further improve the generalization performance of the model. Finally, the experimental results on multiple datasets show that the proposed method achieves better performance than other methods in most cases.

Abstract： Aiming at the limitation of sparse representation depended on large training sample dictionaries for traditional super-resolution reconstruction method, this paper proposed an improved super-resolution reconstruction method for self-learning of single image based on the characteristic of l₂ norm's weak sparsity. Firstly, it used self-learning to established the non pyramid stepped training images; then, it used the custom method to extract feature blocks and feature pixel values of corresponding LR and HR images; finally, combined with the collaborative representation (CR) theory of l₂ norm and support vector regression (SVR) technology, it established mapping model of the super-resolution. Experimental results show that the proposed super-resolution method is not only feasible and effective, but also the average PSNR increases for 0.06~3.92 dB and SSIM increases for 0.002 4~0.034 8 compared with other conventional super-resolution approaches of single image. From the objective and subjective vision, it is proved that the proposed method is excellent.
