Due to the growth of industries and factories, deforestation and other environmental degradation as well as greenhouse gases have been increasing on the Earth's surface in recent decades. This increase disturbs the climate of the Earth and is called climate change. An Increase in greenhouse gases in the future could exacerbate the climate change phenomenon and have several negative consequences...

Background and Purpose: Climate change has major impact on water cycle, resulting in effects on water resources, the frequency and severity of droughts, floods due to severe rainfall, natural environments, society, and economics and human health.  In this paper, surveys on different models of climate change as well as the effects of climate change on the burden of waterborne diseases and also, ...

Growing concerns about climate change and energy security have led to a strong focus on energy efficiency within UK energy policy. At the same time, information and communication technologies (ICTs) have become pervasive in society and this has brought with it new policy options which use them as enabling technologies. One such policy option planned for implementation in the UK is the use of sm...

China’s sugar production and consumption continues to increase. This process is alreadyongoing for over 15 years and over 90% of the sugar production comes from sugarcane(Saccharum officinarum). Most of the sugarcane is planted in the south (e.g. the Chineseprovinces of Yunnan, Guangxi, Guangdong and Hainan) and it represents there a majoreconomic crop in these landscapes. As found virtually wo...

Using panel data for a cross-section of countries, several previous studies estimate the effect of advertising bans on cigarette consumption. These studies suffer from three problems: (1) structural change in cigarette demand functions; (2) endogeneity of advertising bans; and (3) non-stationarity of cigarette consumption data. Using annual data for 20 OECD countries, this study tests for unit ...

To identify countermeasures to the effects of climate warming on crop production, we mustunderstand the changes in crop phenology and the relationships between phenology and climatechange and cultivar. We used summer maize phenological and climate data in the North ChinaPlain, collected from 1981 to 2010. This study analyzed the spatiotemporal trends inphenological data and lengths of different...

Electricity systems are undergoing unprecedented change, with growing capacity for low-carbon generation, and an increasingly distributed approach to network control. Furthermore, the severity of climate related threats is projected to increase. To improve our understanding of the risks from these changes, this paper presents a novel modeling approach to assess the resilience of future electric...
