That categorization results from the understanding that citizens only need to move around urban perimeters. However, the current bus models available do not fully meet legal demands or cater for all of society's demands. Rural workers and students that live in rural areas also must be conveyed in buses and minibuses. Municipal and state directives prohibit employers to convey them in improper vehicles, such as trucks. Social demands, on the other hand, can be i[llustrated by federal and state programs that provide vehicles to transport students who dwell in rural settings. Accordingly, this paper proposes a new categorization of bus models available in the Brazilian market, which should account for the unique local operating conditions rural buses face, instead of only considering the type of service they provide. Further, a purpose-built vehicle is suggested i[n order to cater for the needs of rural workers and students. Rural students represent, in average, five million rural school bus riders.展开更多

This thesis starts with the essence, function, and other influential factors of this idea, systematically elaborates the current idea characteristics of each stratum in western countryside, discovers the reason that the sense of western rural areas falls behind the times, and definitely puts forward with new idea characteristics which is suitable for the economic development of the western rural areas, and also offer some policy suggestions on how to realize this change of the sense in western rural areas.展开更多

Migration and remittances reduce households' firewood consumption due to increases in both income and opportunity cost of firewood collection. Previous studies have been equivocal because they ignored uncertainty in household economy, which is widespread in forest areas of less developed countries. This study provides additional insight by considering vulnerability and subjective assessment of poverty generated by unstable income and an uncertain future. We provide evidence that the amount of firewood consumed depends on income and opportunity cost of firewood collection, but also on a prudent consumption strategy, due to farmers' subjective assessment of their future possible poverty. We also find out-migration of labor can reduce per capita firewood consumption but subjective poverty also acts against reduction of firewood consumption.展开更多

Data obtained are fundamental parameters for the planning of urban solid waste management systems in Mexico, complying this way with the established policy in the National Program for Waste Management and Prevention 2009-2012. The study was carried out during five days and two main parameters were assessed: (1) the daily generation rate per person and (2) the waste composition. The per capita waste generation was 0.958 kg for the urban community and 0.631 kg for the rural. The results showed that the mean composition of waste from both locations was statistically similar (a = 0.05). In both locations the most important contribution was the fraction of food waste. In both locations more than 60% of the waste is potentially recyclable. The results of this study will be used by the municipal waste authorities in order to establish an integrated waste management plan.展开更多

In practice, however, the lack of coordination measures necessary between rural tourism and new rural, leading to interoperability between the two thrust did not really been achieved. On the basis of analyzing current interaction of Liangshan rural tourism development and new rural construction, it focus more on discussing the strategy of developing rural tourism in Southwest National Area and the construction of new socialist countryside.展开更多
