Elaine Leong Supervisor at LiU: Niclas Svensson Examiner at LiU: Niclas Svensson Supervisor at Shell Global Solutions: Gert-Jan Kramer Master Thesis LIU-IEI-TEK-A--13/01600—SE Department of Management and Engineering Sub-department 2 This page is left blank with purpose 3 Summary Several studies indicates China is experiencing a water crisis, were several regions are suffering of severe water scarcity and rivers are heavily polluted. On the other hand, water is used inefficiently and wastefully: water use efficiency in the agriculture sector is only 40% and within industry, only 40% of the industrial wastewater is recycled. However, based on statistical data, China’s total water resources is ranked sixth in the world, based on its water resources and yet, Yellow River and Hai River dries up in its estuary every year. In some regions, the water situation is exacerbated by the fact that rivers’ water is heavily polluted with a large amount of untreated wastewater, discharged into the rivers and deteriorating the water quality. Several regions’ groundwater is overexploited due to human activities demand, which is not met by local. Some provinces have over withdrawn groundwater, which has caused ground subsidence and increased soil salinity. So what is the situation in China? Is there a water crisis, and if so, what are the causes? This report is a review of several global water scarcity assessment methods and summarizes the findings of the results of China’s water resources to get a better understanding about the water situation. -

*Use the Notes to Answer the Questions. Asia: •The Vast Continent of Asia Has Many Different Mountain, Desert, and Water Features
*Use the notes to answer the questions. Asia: •The vast continent of Asia has many different mountain, desert, and water features. •Icy mountain ranges are located in the north, while steamy rainforests lie in the south. •A large part of Asia is desert, yet much of southern and eastern Asia receives massive amounts of rain each year. •These features impact trade and affect where people live. IMPACT OF MOUNTAINS: Himalayas: •The Himalayas are a mountain range with some of the tallest peaks in the entire world. •They have a significant impact on life in southwest China and northwest India. •Hydroelectric power plants have been built on glaciers throughout the Himalayas continued: •India is separated from the rest of Asia on three sides by mountain ranges. •On India’s side of the Himalayas, the high mountains trap rain clouds, so rainforests and grasslands can be found. •The Chinese side of the icy Himalayas receives very little rainfall and the population is much lower here. Tibetan Plateau: •The Tibetan Plateau covers the majority of western China and is the world’s highest plateau at 14,800 feet above sea level. •Because of the region’s extremely high elevations, it has been nicknamed “the roof of the world”. •Many of Asia’s major rivers begin in the Tibetan Plateau, and are fed by more than 30,000 glaciers that are located here. •In this region, summers are very short and winters are long and extremely cold. •During the few warmer months, farmers are able to let livestock graze in the region’s grasslands. -
Mysterious Carvings and Evidence of Human Sacrifice Uncovered in Ancient City
Mysterious carvings and evidence of human sacrifice uncovered in ancient city Discoveries at the sprawling site have archaeologists rethinking the roots of Chinese civilization. By Brook Larmer PUBLISHED August 6, 2020 The stones didn’t give up their secrets easily. For decades, villagers in the dust-blown hills of China’s Loess Plateau believed that the crumbling rock walls near their homes were part of the Great Wall. It made sense. Remnants of the ancient barrier zigzag through this arid region inside the northern loop of the Yellow River, marking the frontier of Chinese rule stretching back more than 2,000 years. But one detail was curiously out of place: Locals, and then looters, began finding in the rubble pieces of jade, some fashioned into discs and blades and scepters. Jade is not indigenous to this northernmost part of Shaanxi Province— the nearest source is almost a thousand miles away—and it was not a known feature of the Great Wall. Why was it Join archaeologists as they search for clues to the mysterious fate of “China’s Pompeii” in a new three-part series. Ancient China from Above premiers in the U.S. Tuesday August 11 at 10/9c on National Geographic. For all other countries check local listings. When a team of Chinese archaeologists came to investigate the conundrum several years ago, they began to unearth something wondrous and puzzling. The stones were not part of the Great Wall but the ruins of a magnificent fortress city. The ongoing dig has revealed more than six miles of protective walls surrounding a 230-foot-high pyramid and an inner sanctum with painted murals, jade artifacts—and gruesome evidence of human sacrifice. -

Schäpe, Helena Röttgers, Nikita Tychkov 1. Territorial and geographical location Ili Delta, Kazakhstan Almatinskaya Oblast (province), Bakanas Rayon (county) The Ili Delta is part of the Ramsar Site Ile River Delta and South Lake Balkhash Ramsar Site 2. Natural and geographic data Basic geographical data: location between 45° N and 46° N as well as 74° E and 75.5° E. Fig. 1: Map of the Ili-Balkhash Basin (Imentai et al., 2015). Natural areas: The Ramsar Site Ile River Delta and South Lake Balkhash Ramsar Site comprises wetlands and meadow vegetation (the modern delta), ancient river terraces that now harbour Saxaul and Tamarx shrub vegetation, and the southern coast line of the western part of Lake Balkhash. Most ecosystem services can be attributed to the wetlands and meadow vegetation. Therefore, this study focusses on the modern delta with its wetlands and meadows. During this study, a land cover map was created through classification of Rapid Eye Satellite images from the year 2014. The land cover classes relevant for this study were: water bodies in the delta, dense reed (total vegetation more than 70%), and open reed and shrub vegetation (vegetation cover of reed 20- 70% and vegetation cover of shrubs and trees more than 70%). The land cover class dense reed was further split into submerged dense reed and non-submerged dense reed by applying a threshold to the short wave infrared channel of a Landsat satellite image from 4 April 2015. -

Nuclear Deterrence and Conventional Conflict
VIEW Sticks and Stones Nuclear Deterrence and Conventional Conflict DR. KATHRYN M.G. BOEHLEFELD n the night of 15 June 2020, Sino- Indian tensions flared into fighting along the disputed border in the region known as the Galwan Valley. The fighting led to the first casualties along the border in 45 years. However, Ono one on either side fired a single shot.1 Instead, soldiers threw rocks and used wooden clubs wrapped in barbed wire to attack one another. Two of the most powerful armies in the world, both of which possess nuclear weapons, clashed with one another using sticks and stones. Nuclear weapons prevent nuclear states from engaging in large-scale conven- tional war with one another, or at least, the existence of such advanced weapons has correlated with a significant decrease in conventional war between nuclear- armed adversaries over the past 80 years. Nuclear weapons tend to make nuclear adversaries wearier of engaging in conventional warfare with one another because they fear inadvertent escalation: that a war will spiral out of control and end in a nuclear exchange even if the war’s aims were originally fairly limited. However, this fear has not fully prevented the Chinese and Indian militaries from engaging in skirmishes, like the one that occurred in June 2020. Where does escalation to- ward nuclear war start, and what does this conflict teach both us and major world players about the dangers and opportunities associated with low levels of conflict between nuclear powers? Escalation to nuclear use may occur as a deliberate and premeditated choice or inadvertently as the result of a security dilemma, the offensive nature of militaries, and/or due to the fog of war.2 This article argues that the Sino- Indian border dispute demonstrates that the drivers of inadvertent escalation may be present even at exceptionally low levels of conflict.
