Geography and Disaster Management


General Studies Paper -1 Context: The Uttarakhand government has constituted two teams of experts to evaluate the risk posed by five potentially hazardous glacial lakes in the region. These lakes are prone to Glacial Lake Outburst Floods (GLOFs). What are GLOFs? GLOFs are disaster events caused by the abrupt discharge of water from glacial lakes — large bodies of water that sit in front of, on top of, or beneath a melting glacier. As a glacier withdraws, it leaves behind a depression that gets filled with meltwater, thereby forming a lake. The more the glacier recedes, the bigger and more....Read More

General Studies Paper -1 Context: Recently the Odisha government announced measures for the welfare of tribal Population. The Odisha government announced the launch of LABHA (Laghu Bana Jatya Drabya Kraya) Yojana, for minor forest produce (MFP). It has also approved the establishment of aCommission for the Preservation and Promotion of the Tribal Languages of the Scheduled Tribes of Odisha. LABHA (Laghu Bana Jatya Drabya Kraya) Yojana It is a 100% State-funded minimum support price (MSP)scheme for minor forest produce (MFP). The MSP will be determined every year by the State government. Under the scheme, a primary collector (a tribal person) will be able....Read More

General Studies Paper -1 Context: Rajasthan and Madhya Pradesh signed a Memorandum of Understanding (MoU) with the Union Ministry of Jal Shakti to implement the Modified Parbati-Kalisindh-Chambal-ERCP (Modified PKC-ERCP) Link Project. The project envisages integration of the long-pending PKC river link project with the Eastern Rajasthan Canal Project, under the national perspective plan of interlinking of rivers (ILR) programme. PKC: The Parbati-Kalisindh-Chambal (PKC)link project is one of the 30 links included in the National Perspectives Plan. ECRP:The Eastern Rajasthan Canal Project (ERCP) is aimed at intra-basin transfer of water within the Chambal basin, by utilising surplus monsoon water. Linking of Both Project:Rajasthan came up with the proposal of the ERCP in 2019, and to....Read More

General Studies Paper - 1 Context: Indian Tsunami Early Warning Centre (ITEWC) stated that there is no tsunami threat to India following the Tsunami in Japan. Tsunami: Tsunami (a Japanese word that means “harbor wave”) is a series of giant ocean waves caused by earthquakes or volcanic eruptions under the ocean. The formation of a tsunami can depend on a host of factors, including the shape of the ocean floor, and the earthquake’s distance and direction. The speed of a tsunami depends on the depth of the water it is traveling through. The deeper the water; the faster the tsunami.....Read More

General Studies Paper – 1 Context: After the landfall of Cyclone Michuang, there is a need to take preventive measures to avoid urban flooding in India. Floods: Increased incidence of high-intensity rainfall in short duration is mainly responsible for floods. It is further compounded by unplanned growth, encroachment of natural water bodies, poor drainage system, etc. Urban flooding is significantly different from rural flooding as urbanisation leads to developed catchments, which increases the flood peaks from 1.8 to 8 times and flood volumes by up to 6 times. According to the World Meteorological Organization (WMO), flood-related catastrophes have increased by....Read More

General Studies Paper 1 Context India’s urban areas have been flooding more and more often, destroying lives and livelihoods. Yet, according to a study led by the World Bank and published in Nature recently, flood risk in many cities is rising because they are expanding into flood prone areas. Findings of the paper: According to the paper, since 1985, human settlements in flood prone areas have more than doubled. Experts say the findings spotlight the risk of unsustainable urbanisation in India. The study also found that middle income countries like India have more urban settlements in flood prone zones than....Read More

General Studies Paper 1 Context The G20 Summit and India’s success in disaster risk reduction are an opportunity to accelerate international cooperation and build resilience to risks. About Risks are being created faster than they are being reduced. The aftershocks of the COVID-19 pandemic, combined with a polycrisis of war, debt, and food insecurity, are putting our collective ability to cope to the test. The rise in disasters is a trend, not an aberration. Headlines this year alone have brought a relentless wave of bad news across the world, from severe flooding in China to destructive wildfires in Europe and....Read More

General Studies Paper 1 Introduction Torrential rains in several parts of north India, particularly Himachal Pradesh and Uttarakhand, damaged highways and buildings, and took hundreds of lives. While a warming Arctic is said to be a cause for the unusually heavy rains, years of haphazard planning and construction have multiplied the tragedy. Natural calamities Every year, particularly in the monsoon, we witness extreme natural calamities. The scale of natural disasters that we now see across the world are definitely man-made. Some sections of the population are more vulnerable to them and more at risk than others. We need to figure....Read More

Save the Water

General Studies Paper 1  CONTEXT During the last few years, the delay in onset of monsoon is observed, for e.g., recently, it arrived in Mumbai and New Delhi on the same day June 24. The monsoon’s onset in these cities is generally around June 10 and June 30, respectively. As, immediately after its arrival, many places across India received heavy to very heavy rainfall. It is unusual to see flooded rivers and cities in June/early July since most of the flooding usually occurs in the later months of the monsoon. THERE IS NEED FOR FLOOD MANAGEMENT TO HANDLE THE FLOOD....Read More

General Studies Paper 1 Context- Global warming's effects on cyclogenesis over the Pacific and North Indian Oceans, the warming over the North Indian Ocean and the late pre-monsoon cyclones and typhoons are another monkey wrench in the monsoons' dynamics – and in the predictions of the monsoon’s onset and its evolution through the season. The impact We are seeing cyclone formations in the pre-monsoon cyclone season, closer to the monsoon onset, arguably due to the influence of a warmer Arctic Ocean on the winds over the Arabian Sea. The monsoon is of course also affected by the three tropical oceans....Read More
