![]() ![]() ![]() Understanding the impacts of land-use mosaics on elephant distribution and the patterns of habitat use is essential for their conservation in modified landscapes. Based on empirical results, specific policy recommendations are provided for Chinese power enterprises. Third, due to their high economic development and advanced use of technology, the CER efficiency of power enterprises in subtropical regions is higher than that in temperate regions. Most power enterprises in China need to take measures to further reduce carbon emissions and improve the efficiency of resource utilization. Second, only 30% of Chinese power enterprises have both high CER and ESER efficiency. First, the average ESER efficiency of Chinese power enterprises is lower than their CER efficiency. The data envelopment analysis was applied to obtain the CER efficiency and the ESER efficiency of power enterprises in subtropical and temperate regions of China. The purpose of this study is to analyze the carbon emission reduction (CER) performance and the ESER performance of China’s power enterprises. ![]() To reduce carbon emissions and save energy, China has implemented various energy-saving and emission reduction (ESER) policies in the power industry. To mitigate adequately the negative impacts induced by anthropization and climate change, the characteristics of mangrove forest configuration and human activities should therefore both be considered.Ĭhina’s power enterprises consume a large amount of energy and emit a high quantity of carbon dioxide. We also found that differences in geometrical properties influenced the spatiotemporal patterns of mangroves. This increase in salinization is a result of anthropogenic activities and climate change. An increasing trend of mangrove coverage was observed and can be related to the salinization. We found that the technique was a synthetical and cost-effective way of observing land-use changes over the study period, and its precision was evident for local-scale study. This study is the first time the grid technique has been used as a precise method to quantify and localize the mangrove coverage changes at local scale. ![]() Using the grid technique, Landsat images of three estuaries in Pernambuco, northeast Brazil, were analyzed to track changes in land use over the past three decades. It is essential to monitor both the mangrove coverage and the encroachment of anthropogenic activities to assess the evolution of these highly valuable and threatened ecosystems. ![]()
