Abstract
Based on the connotation of the intensity of marine resources consumption, this paper measures the intensity of marine resources consumption in China’s coastal provinces from 1996 to 2015, reveals its spatio-temporal evolution characteristics, establishes a factor decomposition model by using the improved logarithmic mean Di exponential decomposition (LMDI), analyzes the factor contribution of changes in the intensity of marine resources consumption in China, and compares the differences. The results sh ow that: ( 1) f rom 1996 to 2015, the overall consumption intensity of China ’ s marine resources increased first and then decreased steadily, and the consumption intensity of resources in the primary industry decreased steadily, ranking second . The resource con sumption intensity of the tertiary industry is basically synchronized with the change trend of China’s marine resource consumption intensity; in the evolution of spatial pattern, the provinces with medium and high intensity of marine resource consumption grad ually reduce, while the provinces with low intensity provinces gradually increase, and the regional differences gradually narrow. ( 2) The contribution rates of technological progress effect, industrial structure effect and regional scale effect to the decline of China ’ s marine resource consumption intensity are 78.224%, 18.334% and 3.442%, respectively; there are significant differences in factor decomposition effects among coastal provinces, among which Fujian is dominated by technological progress effect, Zhejiang, Shandong and Hainan are dominated by technological progress effect and regional scale effect, Tianjin, Hebei and Jiangsu are dominated by technological progress effect and industrial structure effect, while Liaoning, Shanghai, Guangdong and Guangxi are jointly drive n by technological progress effect, industrial structure effect and regional scale effect to reduce the intensity of marine resource consumption. ( 3) From the perspective of the three marine industries, the effect of technological progress is the largest con tribution within the secondary industry, accounting for 77.118% in total; the industrial structure effect has the largest contribution within the primary industry, accounting for 314.547% in total. There is no significant difference in regional scale effect among the three industries. Different provinces and regions should pay different attention to the implementation of technologies or measures for the intensive utilization of resources in the three marine industries.

Abstract
E nergy and water resources are very important for human survival and social development. Energy and water footprint can reflect the real occupation of water resources in the process of energy production. Based on the energy and water footprint evaluation model, this paper calculates the life cycle water footprint of fossil energy and power production in 30 provinces (cities and autonomous regions) in China, studies the temporal and spatial pattern evolution characteristics of China’s raw coal, crude oil, natural gas, hydropower and thermal power from 2004 to 2016, and analyzes the spatial matching relationship between China’s energy and water footprint and water resources. The results show that: ( 1): during the study period, the water footprint of fossil energy increases first and then decreases with 2012 as the boundary. The rapid growth of hydropower water footprint promotes the continuous growth of power water footprint. (2 ): In terms of spatial pattern, the water footprint of fossil energy increases in the West and decreases in the East with the Huhuanyong line as the boundary, and the Inner Mongolia, Shanxi and Shaanxi region as the high-value concentration area; in the power water footprint, there is a significant spatial boundary between hydropower water footprint and thermal power water footprint. The rapid growth of hydropower water footprint has gradually formed a high-value concentration area of power water footprint in the Yangtze River Basin, the Pearl River Basin and the southeast coast. (3): The spatial matching degree of energy and water footprint and water resources fluctuates and declines in the pattern of high in the south and low in the north. The spatial matching degree of fossil energy and water footprint is lower than that of electric power and water resources. The energy water contradiction between raw coal production and thermal power generation is the most prominent. One third of the country has the problem of energy water mismatch. North China with high energy and water footprint has great pressure on energy water matching. The contradiction between energy production and water resources allocation still exists. Truly reflect the matching relationship between energy and water footprint and water resources, help to optimize the comprehensive management of energy and water resources, and provide a quantitative basis for maximizing the energy water synergy.

Abstract
This paper contextualizes the economic environment of the productive sectors that depend on the intensive use of water resources in the Colombian Amazon basin (it is composed of the departments of Amazonas, Caquetá, Guainía, Guaviare, Putumayo, Vaupes, La Bota Caucana and southern Nariño) through the collection and organization of information from official entities and consultations in the region carried out by the Amazon Scientific Research Institute ( ASRI ). Macroeconomic indicators of the Amazonian departments in each of the different sectors were analyzed considering the added value exposed in the annual average of the Gross Domestic Product (2000–2012 in constant values) and contrasted with the sectoral demand for water and the growth projection, both of the human population and the growth trends of the economic activities. As a relevant result, it was found that the departments with a mining-energy tradition base their economic growth on the intensive use of water (greater pressure on the resource in m3/year). An average annual value of $374.42 million dollars is reported in water use (economic cost for the department of Putumayo alone) for oil extraction, which will increase in the future. This value has not been offset by the department, let alone taken into account in the economic growth indicators. It is concluded that the policy guidelines for water resource management in Colombia should be differentiated by sectors and by departments, considering the economic dynamics in the demand for water use and the heterogeneity of the populations.

Abstract
Water shortage is a global problem, and China is one of the most water-scarce countries in the world. The reverse distribution of coal resources and water resources has made the protection and utilization of water resources for coal mining in China a major technical problem for the green development of coal. Western China has become the main coal-producing area, but the ecological environment in the region is fragile, the evaporation of water resources is large, and the evaporation loss after mine water discharge is the main reason for the current annual loss of 6 billion tons of mine water in coal mining in China. The technical progress and engineering application characteristics of the protection and utilization of water resources in coal mining are systematically analyzed. After nearly 20 years of technical exploration and engineering practice, Shenhua Group broke through the traditional concept, put forward the technical concept of mine water storage in the goaf for the first time, overcome the technical problems such as water source prediction, reservoir site selection, reservoir capacity calculation, dam construction, safety control and water quality assurance, and built a technical system for underground coal mine reservoirs. This technology has been fully implemented in the Shendong mining area, and will be promoted and applied in other mining areas in the western region, opening up an effective technical way for the protection and utilization of coal mining water resources.
