To overcome the limitations of present grey models in spatial data analysis, a weight matrix is incorporated into discrete model to create SDGM(1,1,m) model, and L1-SDGM(1,1,m) proposed, considering time lag effect realize simultaneous forecasting data. The validation achieved, finally, per capita energy consumption levels (PCECs) 30 provinces China from 2020 2025 predicted using with metabolic...

Globally and in the United States, agriculture is the major user not only of water but also of land. This paper compares trends in aggregate and per capita water and land use by the agricultural sector in the United States and the world during the 20 century. It finds that although cropland use per capita has been declining in both areas since the early 1900s, agricultural water use per capita ...

Ancient civilizations may have dispersed or collapsed under extreme dry conditions. There are indications that the same may hold for modern societies. However, hydroclimatic change cannot be the sole predictor of the fate of contemporary societies in water-scarce regions. This paper focuses on technological change as a factor that may ameliorate the effects of increasing water scarcity and as s...

Resource productivity and evidence of economic decoupling were investigated on the basis of the time series in 1996-2011 of material flow analysis for Sweden, Stockholm, and Gothenburg. In the three cases, absolute reductions in CO2 emissions by about 20% were observed, energy consumption per capita decreased, while gross domestic product (GDP) per capita grew. The energy consumption of the res...
