In the year 1996, a fire burned nearly 12,000 acres around Buffalo Creek, which serves as the main source of the city's water supply. Two months following this devastating wildfire, heavy thunderstorms caused flash floods in the burned area, having the effect of washing sediment into the city's reservoir. In fact, this event washed more sediment into the reservoir than had accumulated in the 13 years prior. Water treatment costs were estimated to be $20 million over the next decade following the event. Denver needed a plan to make sure that the city would not be devastated by future wildfire and flash flood events. DenverWater and the U.S. Forest Service Rocky Mountain Region are working together to restore more than 40,000 acres of National Forests lands through processes like reforestation, erosion control, and the decommissioning of roads. Further, Denver has installed sensors in the reservoirs in order to monitor the quality of the water and quantity of debris or sediment. These accomplishments will have the effect of building a more resilient Denver, Colorado towards the impending increase of extreme weather events such as wildfire and flooding. China has been rapidly emerging as a new superpower, rivaling the United States. As the most populated country in the world, and one of the leaders of the global economy, China's response to the impending effects of climate change is of great concern for the entire world. A number of significant changes are expected to affect China as the looming threat of climate change becomes more and more imminent. Here's just one example; China has experienced a seven-fold increase in the frequency of floods since the 1950s, rising every decade. The frequency of extreme rainfall has increased and is predicted to continue to increase in the western and southern parts of China. The country is currently undertaking efforts to reduce the threat of these floods (which have the potential effect of completely destroying vulnerable communities), largely focusing on improving the infrastructure responsible for tracking and maintaining adequate water levels. That being said, the country is promoting the extension of technologies for water allocation and water-saving mechanisms. In the country's National Climate Change Policy Program, one of the goals specifically set out is to enhance the ability to bear the impacts of climate change, as well as to raise the public awareness on climate change. China's National Climate Change Policy states that it will integrate climate change policies into the national development strategy. In China, this national policy comes in the form of its "Five Year Plans for Economic and Social Development". China's Five Year Plans serve as the strategic road maps for the country's development. The goals spelled out in the Five Year Plans are mandatory as government officials are held responsible for meeting the targets.
