Bioenergy from energy plants is an alternative fuel that is expected to play an increasing role in fulfilling future world energy demands. Because cultivated land resources are fairly limited, bioenergy development may rely on the exploitation of marginal land. This study focused on the assessment of marginal land resources and biofuel potential in Asia. A multiple factor analysis method was used to identify marginal land for bioenergy development in Asia using multiple datasets including remote sensing-derived land cover, meteorological data, soil data, and characteristics of energy plants and Geographic Information System (GIS) techniques. A combined planting zonation strategy was proposed, which targeted three species of energy plants, includingPistacia chinensis (P. chinensis), Jatropha curcas L. (JCL), andCassava. The marginal land with potential for planting these types of energy plants was identified for each 1 km2pixel across Asia. The results indicated that the areas with marginal land suitable forCassava,P. chinensis, andJCLwere established to be 1.12 million, 2.41 million, and 0.237 million km2, respectively. Shrub land, sparse forest, and grassland are the major classifications of exploitable land. The spatial distribution of the analysis and suggestions for regional planning of bioenergy are also discussed.

The requirements of “two-oriented society” (resource-conserving and environment- friendly society) is dissected in the urban agglomeration planning, clarifying that the transformation of planning pattern and land resources use pattern should be carried out by the urban agglomeration planning under the “two-oriented society” background and the emphasis of planning should turn to the construction of public space and neighborhood relationship as well as prior layout of green space and urban open space. Through the understanding of regional planning on the connotation, orientation and core target of “two-oriented society”, analyst difficulties and problems “two-oriented society” construction in Changsha-Zhuzhou-Xiangtan agglomeration was currently faced with, research on the establishment of “two-oriented society”, implementation methods and emphasis of regional planning was conducted. Additionally, aiming at the reality of Changsha-Zhuzhou-Xiangtan urban agglomeration, it proposes construction strategies and suggestion for the planning in the context of “two-oriented society” construction.

Suitable Land

As a foodstuff crop, Jerusalem artichoke has a promising prospect for providing sustainable feed-stock sources for bioenergy development. Due to relatively limited cultivated land resources in China, it is crucial to evaluate Jerusalem artichoke’s potential production capacity in marginal land. Based on Jerusalem artichoke’s growth and photosynthetic characteristics, the agricultural production systems simulator model (APSIM) and multi-factor integrated assessment method were integrated to provide an operational method for comprehensively evaluating the marginal land resources suitable for developing the plantation of Jerusalem artichoke in the Shaanxi province, China. The results showed that 0.73 million ha of marginal land was suitable for Jerusalem artichoke cultivation in the Shaanxi province, and 5.4 million ha of marginal land was fairly suitable for Jerusalem artichoke cultivation, with the yield reaching 44,289 kg/ha and 38,861 kg/ha, respectively. The suitable land resources are mainly located in Yan’an (0.18 million ha), Hanzhong (0.13 million ha), and Baoji (0.08 million ha), most of which are moderate dense grassland (accounting for 50.6% of suitable land), dense grassland (accounting for 16.2% of suitable land), shrubland (accounting for 14.7% of suitable land), and sparse forest land (accounting for 9.18% of suitable land). The findings of this study can be used to establish targeted policies for Jerusalem artichoke development in China and other countries, particularly those along the Silk Road.

The Impact

China has been going through urbanization, and foreign experiences show that urbanization would finally lead to integrated planning and development of region. In regional planning, traffic network is an important aspect, which affects the impact of cities. However, in traditional accessibility analysis, only traffic lines are taken into consideration, while the influence of stations is ignored. This lead to the actual problems that traffic facilities cannot play the roles designed in regional planning when they are really constructed. Therefore, firstly, two rank traffic networks system are proposed, and different traffic networks with the normalization costs are combined to analyse the accessibility of the cities. Secondly, a new accessibility analysis method to get arrival domain for a city is proposed, which take not only the traffic lines but the traffic stations into consideration. Finally, the Jing-Jin-Ji Region is taken as an instance to show the effect of the new method.

Abstract Background Households, as end energy users, consume grid electricity to meet their energy demands. However, grids across the globe for energy production are majorly based on fossil fuel technology and make the highest contributions to global warming and climate change due to greenhouse gases (GHG) emissions. This generic study aims to investigate the minute role of a single-end energy consumer in GHG mitigation by switching to a rooftop PV system to meet his energy demands and trading surplus energy to the grid through its techno-economic analysis. Method For the study impact, NASA Meteorological Data are used to select an ideal single energy user equipped with a 10-kW PV system based on annual average daily solar radiation and ambient temperature through MATLAB/Simulink, for 11 populous cities in Pakistan. Helioscope software is used to select tilt and azimuthal angles to maximize the solar radiation intercept. Afterward, RETScreen software is used for cost, financial and GHG analysis. Result and conclusion A single end energy user equipped with a 10-kW PV system switched to a green energy source from a fossil fuel-based grid has the potential to avoid the burning of 3570.6 L of gasoline by producing 16,832 kWh of green energy per annum, while financially recovering the 10-kW PV system’s 7337$ grid-tied investment in 5 years (equity) and in 9 years (equity) in a 9077$ stand-alone system over its 25-year life. This approach provides relief to end energy users from high priced grid electricity through environmental friendliness by mitigating 8.3 tons of CO2 equivalent emissions per annum from energy production, while providing relief to the main grid by grid stabilization through peak shaving, in the broad sense.
