Within this context, the German Aerospace Centre (DLR) has developed a new suite of global layers, which accurately describe the built-up environment and its characteristics at high spatial resolution: (i) the World Settlement Footprint 2015 layer (WSF-2015), a binary settlement mask; and (ii) the experimental World Settlement Footprint Density 2015 layer (WSF-2015-Density), representing the percentage of impervious surface.

  • Cultural Reflections on the Popularity of Chinese Learning
    CHAPTER 3 Cultural Reflections on the Popularity of Chinese Learning Zhao Lin The Historically Inevitable Emergence of the “Chinese Learning” Craze Recently, a cultural resurgence has occurred in China that has compelled widespread attention: the emergence of the popularity of Chinese learning.1 Many universities have established sinological academies, sinological research institutes, and a prodigious number of sinological forums with varying inter- pretations of traditional Confucianism, Buddhism, and Daoism. In every city square, all kinds of old customs and new things are borrowing from prestige of “Chinese learning.” Many major events, such as Confucian rituals at the Temple of Confucius and paying homage to the Tomb of the Yellow Emperor, have made a lot of noise with their massive displays; even the practices of geo- mancy ( fengshui), divination, and astrology are plying their arts. This inher- ently complex “Chinese learning craze” has a very strong appeal and tempers the intensity of China’s rapid economic growth and ideals of its revival as an international power. The Chinese learning craze gives the face of the Chinese cultural spirit an image in stark contrast to the “wholesale Westernization” of the early reform period in China. In relation to the global culture that emerged at the end of the cold war, this “Chinese learning craze” seems to pos- sess culturally conservative values, demanding cultural “modernization, not Westernization.” This is manifested as a conscientious national cultural iden- tity while also having imperfections

  • Patterns of Population Distribution and Density Help Us to Understand the Demographic Characteristics of Any Area. the Term Popu
    B.A. PART - 3 ( POPULATION GEOGRAPHY : PAPER - 7) TOPIC : PATTERNS OF POPULATION DISTRIBUTION IN THE WORLD - Prof. KUMARI NISHA RANI Patterns of population distribution and density help us to understand the demographic characteristics of any area. The term population distribution refers to the way people are spaced over the earth’s surface. Broadly, 90 per cent of the world population lives in about 10 per cent of its land area. The 10 most populous countries of the world contribute about 60 per cent of the world’s population. Of these 10 countries, 6 are located in Asia. FACTORS INFLUENCING THE DISTRIBUTION OF POPULATION A. Geographical Factors (i) Availability of water: It is the most important factor for life. So, people preferto live in areas where fresh water is easily available. Water is used for drinking, bathing and cooking – and also for cattle, crops, industries and navigation. It is because of this that river valleys are among the most densely populated areas of the world. (ii) Landforms: People prefer living on flat plains and gentle slopes. This is because such areas are favourable for the production of crops and to build roads and industries. The mountainous and hilly areas hinder the development of transport network and hence initially do not favour agricultural and industrial development. So, these areas tend to be less 1 populated. The Ganga plains are among the most densely populated areas of the world while the mountains zones in the Himalayas are scarcely populated. (iii) Climate: An extreme climate such as very hot or cold deserts are uncomfortable for human habitation.

  • Westernization of Asian Diets and the Transformation of Food Systems: Implications for Research and Policy
    Westernization of Asian Diets and the transformation of food systems: Implications for research and policy Prabhu Pingali ESA Working Paper No. 04-17 September 2004 Agri cultural and Development Economics Division The Food and Agriculture Organization of the United Nations www.fao.org/es/esa Westernization of Asian Diets and the transformation of food systems: Implications for research and policy Prabhu Pingali1 1. Introduction Rapid economic and income growth, urbanization, and globalization are leading to a dramatic shift of Asian diets away from staples and increasingly towards livestock and dairy products, vegetables and fruit, and fats and oils. While the diversification of diets away from the traditional dominance of rice with rising incomes is expected and observed, current food consumption patterns are showing signs of convergence towards a Western diet. Globalization and the consequent global interconnectedness of the urban middle class, is the driving force behind the convergence of diets. The rapid spread of global supermarket chains and fast food restaurants are reinforcing the above trends. The following six key stylised facts characterize the changes in food demand in Asia: i) reduced per capita consumption of rice; ii) increased consumption per capita of wheat and wheat based products; iii) increased diversity in the food groups consumed; iv) rise in high protein and energy dense diets; v) increased consumption of temperate zone products; and vi) the rising popularity of convenience food and beverages. As the demand profile changes with economic growth and globalisation, so the supply systems must adapt to accommodate this change. Asian agriculture is on an irreversible path leading away from its traditional pre- occupation with cereal crop production, especially rice, towards a production system that is becoming increasingly commercialized and diversified.

  • Half the World's Population Are Exposed to Increasing Air Pollution
    www.nature.com/npjclimatsci ARTICLE OPEN Half the world’s population are exposed to increasing air pollution ✉ G. Shaddick 1 , M. L. Thomas2, P. Mudu3, G. Ruggeri3 and S. Gumy3 Air pollution is high on the global agenda and is widely recognised as a threat to both public health and economic progress. The World Health Organization (WHO) estimates that 4.2 million deaths annually can be attributed to outdoor air pollution. Recently, there have been major advances in methods that allow the quantification of air pollution-related indicators to track progress towards the Sustainable Development Goals and that expand the evidence base of the impacts of air pollution on health. Despite efforts to reduce air pollution in many countries there are regions, notably Central and Southern Asia and Sub-Saharan Africa, in which populations continue to be exposed to increasing levels of air pollution. The majority of the world’s population continue to be exposed to levels of air pollution substantially above WHO Air Quality Guidelines and, as such, air pollution constitutes a major, and in many areas, increasing threat to public health. npj Climate and Atmospheric Science (2020) 3:23 ; https://doi.org/10.1038/s41612-020-0124-2 INTRODUCTION coverage of estimated concentrations and obtaining (national- 1234567890():,; In 2016, the WHO estimated that 4.2 million deaths annually could level) distributions of population exposures for health impact be attributed to ambient (outdoor) fine particulate matter air assessment.
