Fenlong green ecological agriculture technology (Fenlong technology), a new smash ridging farming method developed by Guangxi Academy of Agdcultural Sciences, has been elected as the recommended cultivation technique by the Ministry of Agriculture of China. It replaces the traditional plowshare with spiral drill, and its tilth depth is twice deeper than that by tractor tilthing. It also extends soil nutrient, moisture, oxygen and microorganism, the so-called "Four pools". Soil nutrient, oxygen, microorganism, light and rainfall use ratio is increased by 10%-100%, creating a platform for natural increase of more than 10% of crop yield. Its application to over 20 kinds of crops in 21 provinces has proved that the yield increases 10-30% with quality enhancing 5% and double water retaining capacity but no more input. When the application area of Fenlong could reach 67 million hm2, the amount of fertilizer can be reduced by 40-50 billion kg, saving 120-150 billion Yuan. In this paper, we put forward the strategy of "4+1" (arable, saline-alkali soil, grasslands, Sponge City + rivers) green development in China, and deepened the Fenlong cultivated tilled layer from 16.5 cm to 35 cm for 67 million hm2 arable land, ridged 13.3 million hm2 of saline-alkali soil for 35 cm, and also 35 cm for 67 million hm2 degraded steppe, which could have the following 3 effects: first, the 147 million hm2 of land with Fenlong cultivation could increase loosing soil to 315.491 billion m3, in* creasing by 159.26% for 120 million hm2 of arable land with the average tilled layer of 16.5 cm, which has loosing soil of only 198.1 billion m3, that is, the space of the land increases 1.6 times. Second, every hectare of plowland could store up to 450 m3/hm2 of natural rainfall, and the unused 60 m3 of saline-alkali soil and grasslands could store water of 102 billion m3, showing an increase of over 88.89% for the current plowland storage of 54 billion m3 at now, that is, double the natural rainfall storage capacity. Third, the two multiple increase of natural resources application can bring trillions of resource activation, environmental cleaning, food security, citizens, health, economic, ecological and social benefits, and makes the Chinese nation move forward in green development. Its application in "big scientific research" and "One Belt And One Road" will contribute Chinese strength to the world. 展开更多

The analytical method of total resource reallocation effect is an evolution of the analytical method of the factors of economic growth. Since the marketization reform in China in 1978, market mechanism has played a more and more important role in resource allocation, and Chinese economy has developed greatly, which is called "the Chinese Miracle". This paper analyzes the economic growth in China from 1978 to 2004 with the analytical method of total resource reallocation effect. The result shows that the annual growth rate of total resource reallocation effect was 0.2%, which was 5.1% of the comprehensive productivity and 0.21% of the gross output growth, i.e. the total resource allocation played a weak role in the economic growth in China. When analyzing it in Chenery's multinational model, we find that Chinese comprehensive productivity growth rate was higher than that in all the income phases of the model, but the total resource allocation effect was obviously lower than that in all the income phases of the model. It indicates that the total resource allocation in China has a great potential, and that to accelerate marketization reform is one of the important issues for Chinese economic development. 展开更多

In the Benja of Permeti village, eight springs are located in the Lengarica creek, and their curative values are known and used since the time of the Roman Empire. The eight springs erupt mineral water with temperatures in the range of 23-30℃ and yields in the range of 8 up to more than 40 L/s. The geothermal fluid, even though with relatively low temperatures, represent a competitive energy resource. The geothermal water flows directly to the river of Langarica, similarly with the other geothermal resources of Albania can be "translated" as "throwing in the creek" of considerable monetary values, delay in the economic development, infrastructure and also negative social impacts in the region. This paper aims to show that these waters are a competitive energy resource by the implementation of a combined and cascade system, and also they can by efficiently used for greenhouses, aquaculture and salts extraction. 展开更多

The demand for energy, water and food will continuously increase, as the prediction states that 2.5 billion people will be added to the world population by 2050, representing not only an increase in the consumption but also more waste production, greenhouse gas (GHG) emissions and depletion of natural resources. Taking into account that renewable sources of energy can help to overcome these challenges and diversify the energy matrix in the countries, this paper aims at analyzing the biogas potential in Brazil and the United States, especially in the livestock sector, and its benefits in the environmental, social and economic aspects. Both countries are among the top five countries globally in terms of water availability, energy consumption and food production. Until 2050, the world consumption of meat will have a significant increase: 206% of poultry meat, 56% of pork meat and 47% of beef meat, augmenting the need for sustainable management of waste and manure. This scenario can become a sustainable opportunity for biogas implementation, which provides multiple economic, environmental and social benefits for farmers, businesses and communities, including production of electrical, thermal and vehicular energy, production of high-quality biofertilizer, reduction of ground and surface water pollution and reduction of GHG emissions, and foments new income for the farmers, among others. A new concept is presented in this article to make biogas systems feasible, i.e., biogas condominiums, as small and medium-scale farms by themselves usually would not be able to afford the investments. This arrangement can bring benefits for the whole biogas supply chain that includes farmers, agroindustry, providers and local community. 展开更多

The mission of the test field is to provide technical support to associates. The paper present the development of OE (ocean energy) field in China and outline the new technologies and best practice, resources conditions, construction targets, generation device testing and standard system. The main purpose is to improve the level of China's ocean energy development. The Chinese ocean energy test field, which was started in 2008, involved a development divided in three phases (the overall design, construction, demonstration). The methodology followed in the individual phases is described, and the standardization of testing wave and tidal current energy devices is introduced. The research revealed the development and the shortage of ocean energy technology in China. 展开更多
