Background: – While Typhoon Yagi has severely impacted multiple countries, including the Philippines, China, Laos, Myanmar, and Thailand, it has hit Vietnam the hardest, where the death toll stands at around 233. Key takeaways Tropical cyclones form over warm ocean waters near the equator. When the warm, moist air from the ocean surface rises upward, a lower air pressure area is formed below. Air from surrounding areas with higher air pressure rushes into this low pressure area, eventually rising, after it also becomes warm and moist. As warm, moist air rises, it cools down, and the water in the air forms clouds and thunderstorms. This whole system of clouds and winds gains strength and momentum using the ocean’s heat, and the water that evaporates from its surface. Typhoon Yagi started as a tropical storm in the western Philippine Sea on September 1. It made landfall in the Philippines the next day and started to weaken. However, due to unusually warm waters in the South China Sea, the storm intensified again. By September 4, it strengthened into a strong typhoon with Category 3 winds. The next day, it became a Category 5 typhoon with peak maximum sustained winds of 260 kmph. The category of a tropical cyclone is determined by its sustained wind speed, as measured by the Saffir-Simpson Hurricane Wind Scale. It is classified into five categories — Category 1 to Category 5. While Category 1 tropical cyclones bring winds of 119 to 153 kmph, Category 5 tropical cyclones, which are the strongest, have winds of 252 kmph or higher. Storms that reach Category 3 and higher are considered major tropical cyclones due to their potential to inflict significant damage. Additional information: What is the difference between a hurricane and a typhoon? Hurricanes and typhoons are the same weather phenomenon: tropical cyclones. A tropical cyclone is a generic term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation. The weakest tropical cyclones are called tropical depressions. If a depression intensifies such that its maximum sustained winds reach 63 kmph, the tropical cyclone becomes a tropical storm. Once a tropical cyclone reaches maximum sustained winds of 119 kmph or higher, it is then classified as a hurricane, typhoon, or tropical cyclone, depending upon where the storm originates in the world. In the North Atlantic, central North Pacific, and eastern North Pacific, the term hurricane is used. The same type of disturbance in the Northwest Pacific is called a typhoon. Meanwhile, in the South Pacific and Indian Ocean, the generic term tropical cyclone is used, regardless of the strength of the wind associated with the weather system.

Background: – Nearly one-fourth of India’s landmass, about 205 million acres, is estimated to be Commons. Key takeaways Commons is a term used to refer to resources that are not owned by any individual or group or the government, but belong to, and are shared by, the community as a whole. Forests, local ponds, grazing lands, rivers, sacred sites, parks and lakes are all Commons. Commons could be intangible too. Language, folk art or dance, local customs, and traditional knowledge are all shared resources, and thus are Commons. In the digital age, most Internet and open-source software are Commons. Digital resources with creative commons licences are meant to be used freely by everyone. At the international level, the polar regions, the Arctic and Antarctica, are considered global Commons. No country is allowed to take ownership of these areas, even though everyone can use them for certain activities. Outer space, the Moon, and other planetary bodies are also global Commons. Commons are critical for several reasons. They provide a variety of ecological and other services that are beneficial for the entire community. As these resources are accessible to all, they face a greater threat of over-exploitation and damage. Since no one owns Commons, the responsibility of maintenance and upkeep often becomes a problem. Commons have also come under increased stress due to climate change. Different kinds of governance mechanisms have evolved to manage Commons depending on the context. There are international agreements, for instance, for the use and management of polar regions, outer space, and high seas. In India, the 2006 Forest Rights Act (FRA) is considered a good template for managing common forest resources. Additional mInformation: what is the tragedy of the commons? The tragedy of the commons refers to a situation in which individuals with access to a public resource—also called a common—act in their own interest and, in doing so, ultimately deplete the resource. This economic theory was conceptualized in 1833 by British writer William Forster Lloyd. In 1968, the term “tragedy of the commons” was used for the first time by Garret Hardin in Science Magazine. This theory explains individuals’ tendency to make decisions based on their personal needs, regardless of the negative impact it may have on others. In some cases, an individual’s belief that others won’t act in the best interest of the group can lead them to justify selfish behavior.
