The human factors that emit large amount of green house gases include industrialization, burning of fossil fuel and gas flaring. Increase in air temperature and consequent increase in the rates of evaporation also affect the level of food supply. Data for this study were collected from primary and secondary sources. Primary source were collected through field investigation and structured questionnaire. A total of 450 questionnaires were administered. Results revealed that varieties of crops ranging from tree crops to cereals were cultivated within the study area. The effect of climate change on food supply has resulted into change in crop yields, change in rainfall pattern, soil loss and has greatly affected planting period and harvesting. The study therefore recommended awareness campaigns on the causes and consequences of global climate change on food production, environmental education and afforestation campaign programmes on sustainable food supply and environmental safety must be intensified.展开更多

In view of this, we should not only need to attach great importance to energy security, making full use of ＂two markets and two resources＂ to take a variety of channels to ensure oil supply diversification, but also should develop oil security strategy from a strategic level, and actively participate in international oil trading system. Furthermore, we should support China＇ s oil enterprises from the political, financial and other aspects, so as to ensure adequate, stable and affordable supply ofoil to meet China＇ s economic construction requirement.展开更多

At present, the Japanese government has been forced to review the basic energy plan in the wake of the great east Japan earthquake occurred on March 11, 2011 followed by the severe accident at the nuclear power plants in Fukushima. Before the disaster, the IAE （institute of applied energy） had realized that it was not clear how CO2-free hydrogen would contribute to solving various energy and environmental issues, or that prospects were not clear for large demand of CQ-free hydrogen other than FCVs （fuel cell vehicles）. In this connection, the authors organized a voluntary ＂Concept Study Group （in short）＂ in March 2011 and held four meetings until the end of March 2012. Through the quantitative studies using IAE＇s simulation model （GRAPE）, the common recognition was built in the concept study group that hydrogen could contribute to energy security and increase in zero-emissions electric power ratio in Japan. It was also estimated that global CO2-free hydrogen supply chains could be realized by degrees after 2020. Based on these results, the authors made a proposal that hydrogen should be added in the primary energy constitution for new basic energy plan to the Japanese government because imported hydrogen could be considered as a pseudo-primary energy like LNG （liquefied natural gas）. Now, the succeeding ＂Action Plan Study Group （in short）＂ has been held focusing on hydrogen demand in various applications, future pictures of CO2-free hydrogen chains and road maps. Activity results of the ＂Concept Study Group＂ are shown here.展开更多
