    • Storage Reservoirs: These reservoirs are constructed to store excess water during high-flow periods and release it gradually, reducing flood peaks. They also serve as a water source for irrigation, electricity generation, and other purposes.
    • Embankments: These structures, also known as levees, act as barriers to prevent floodwaters from encroaching on vulnerable areas such as agricultural lands, cities, and industries.
    • Diversions: This measure involves redirecting excess water away from heavily populated or susceptible areas to less vulnerable regions, helping to minimize the impact of flooding.

    Non-Structural Measures:

    • Flood Forecasting and Warning Systems: These systems use data analysis, weather monitoring, and hydrological modeling to provide advance warnings about potential flood events. They enable timely evacuation of people and movable assets, reducing the risk to life and property.
    • Flood Plain Zoning: This measure involves regulating the use of floodplains by restricting human activities and developments in flood-prone areas. By delineating zones based on flood risk, it helps minimize vulnerability and losses associated with floods.

    How floods can be a valuable resource?

    • Water Storage: Floods can serve as a valuable resource for water storage. By conserving and capturing floodwaters, the excess water can be stored in reservoirs or other storage facilities. This stored water can then be used for various purposes during dry periods, including irrigation, drinking water supply, and industrial needs.
    • Drought Mitigation: Conserving flood flows can help mitigate the impact of droughts. By storing excess floodwaters, the saved water can be utilized to partially address water scarcity during drought periods, providing relief to agriculture, communities, and ecosystems that rely on water availability.
    • Groundwater Recharge: Floods contribute to the replenishment of groundwater aquifers. The infiltration of floodwaters into the soil helps recharge underground water reserves, ensuring a sustained supply of groundwater for various uses even after the flood event subsides.
    • Ecological Benefits: Floods support ecosystems and promote biodiversity. The article mentions that floods bring essential nutrients, sediments, and organic matter to wetlands and riverine habitats, which nourish the ecosystems and support diverse flora and fauna.
    • Hydropower Generation: Controlled release of floodwaters can be harnessed for hydropower generation. By utilizing the energy of flowing water, floods can be a valuable resource for producing renewable energy through hydropower projects

    The lesson from a monsoon-battered North India: Time to be prepared

  • The lesson from a monsoon-battered North India: Time to be prepared

    monsoon

    What is the news?

    • Last weekend, parts of North India witnessed heavy rains that triggered flash floods and left a trail of destruction, tragically it resulted in at least 50 reported deaths. Himachal Pradesh was the worst affected. Several places in Haryana, Punjab and Himachal Pradesh reported record rainfall.

    Central idea

    • Last weekend, North India faced a calamity as torrential rains triggered flash floods and wreaked havoc across the region. Understanding the factors that led to this catastrophe is crucial in developing effective strategies to mitigate the impact of such extreme weather events in the future.

    Fundamental characteristics of monsoon rainfall in the region

    • Concentrated Timeframe: Monsoon rainfall in the region is not evenly distributed throughout the year. Instead, it occurs within a specific timeframe. All the seasonal rainfall (about 80-100 cm) falls within 130-150 hours, which is a relatively short period.
    • Heavy Rain Contribution: The heavy rains play a significant role in contributing to the overall seasonal precipitation. Half of the seasonal rainfall (40-50 cm) occurs in only 30-40 hours.
    • Runoff: When heavy rains occur, most of the rainwater drains away as runoff, particularly when the soil is already wet. This indicates that a substantial amount of rainfall does not get absorbed into the ground but flows off as surface runoff.

    Factors attributed to the Heavy Downpour in north India

    • Active Monsoon and Moisture Influx: An active monsoon season with strong winds in the lower air layers brought in moisture from the Bay of Bengal and the Arabian Sea. These moisture-laden winds contributed to the heavy rainfall in the region.
    • Atmospheric Forcing and Eastward Moving Troughs: Large-scale atmospheric forcing, in the form of outflows in the upper layers of the atmosphere, moved eastward through mid-latitude troughs. These troughs directed the flow of moisture towards the Himalayan region, exacerbating the intensity of the rainfall.
    • Orographic Uplift and Steep Terrain: The steep terrain of the Himalayas, combined with orographic uplift, played a significant role in intensifying the precipitation. When air masses encounter the mountains, they are forced to rise, resulting in enhanced rainfall.
    • Synoptic Conditions and Moisture Intrusion: The synoptic conditions during the period were conducive to heavy rainfall. The monsoon was active, with strong moist easterly winds entering the region. Additionally, there was moisture intrusion from the North Arabian Sea, further augmenting the rainfall.

    Increasing Trend of Extreme Rainfall

    • Tripled Number of Extreme Rainfall Events: Recent studies indicate that the number of extreme rainfall events, defined as rainfall exceeding 15 cm in 24 hours, has tripled in many parts of the country.
    • Prolonged Duration of Rainstorms: The duration of rainstorms has also tripled, indicating that rainfall events are lasting longer, potentially leading to higher rainfall accumulation.
    • Decreased Number of Rainy Days and Hours: The total number of rainy days and hours during the monsoon season has decreased. This means that when it does rain, it tends to be in the form of heavy downpours rather than spread out over more frequent but lighter rainfall events.
    • Regional Variation: Central India has been particularly affected by the increasing trend of extreme rainfall events, with a significant rise in both frequency and intensity.
    • Himalayan Region Prone to Extreme Rainfall: The Himalayan region, with its complex topography and varied weather patterns, is prone to extreme rainfall events. Studies indicate that 65 percent of areas in the region show a positive trend in the frequency of daily rainfall extremes.

    Impact of Arctic Warming on Monsoon Climate

    • Increased Frequency of Blocking Highs and Mid-latitude Troughs: Arctic warming has been observed to influence the monsoon climate through changes in mid-latitude circulation. As the Arctic warms and sea ice recedes, there is growing evidence of an increased frequency of blocking highs and deep mid-latitude troughs. These atmospheric patterns can affect weather systems and contribute to extreme rainfall events during the monsoon season.
    • Influence on Circulation Patterns: Observations and models suggest that Arctic warming can alter circulation patterns, including the movement of air masses, pressure systems, and wind patterns. These changes can have cascading effects on the monsoon climate, including the transport of moisture and atmospheric conditions that contribute to heavy rainfall events.
    • Impact on Monsoon Dynamics: The warming of the Arctic and subsequent changes in circulation patterns can affect the dynamics of the monsoon. This can lead to shifts in moisture inflow, atmospheric stability, and the timing and intensity of rainfall during the monsoon season.
    • Potential for Future Changes: As Arctic warming continues; it is expected that the impacts on the monsoon climate will persist and potentially intensify. This suggests that the influence of Arctic warming on the monsoon may contribute to further changes in extreme precipitation patterns and associated impacts in the future.

    Way forward: Mitigation Strategies for Flooding

    • Robust Early Warning System: Implement a comprehensive early warning system that utilizes meteorological observations, including Doppler weather radar and high-resolution numerical weather prediction models. Advanced technologies like artificial intelligence and machine learning can aid in interpreting the data, enhancing the accuracy and timeliness of alerts.
    • Continuous Monitoring and Flood Warning Systems: Continuously monitor rainfall patterns, river levels, and deploy an advanced flood warning system. This integrated approach allows for timely response and evacuation plans to safeguard vulnerable communities.
    • Flood Risk Maps: Develop flood risk maps incorporating topography, historical flood data, and hydrological modeling. These maps can identify high-risk zones and guide targeted actions to enhance preparedness and resilience.
    • Climate-Resilient Infrastructure: Improve and maintain climate-resilient infrastructure, including robust drainage systems and channels, to prevent waterlogging and minimize flood damage.
    • Land Use Planning and Zoning Regulations: Implement effective land use planning and zoning regulations, designating flash flood-prone areas as non-residential or restricted zones to mitigate potential risks.
    • Protection and Restoration of Natural Ecosystems: Prioritize the protection and restoration of natural ecosystems such as forests and wetlands. These natural buffers can absorb rainfall and reduce runoff, mitigating the intensity of floods.
    • Public Awareness Campaigns: Conduct widespread awareness campaigns to educate individuals on flood response and preparedness. Encourage actions such as evacuation planning, first aid knowledge, and reliance on credible sources of information during emergencies

    Conclusion

    • Recognizing the escalating threat of extreme precipitation events and implementing proactive measures are pivotal in improving India’s resilience to climate-induced disasters. Building resilience is crucial to safeguarding vulnerable communities and ensuring a sustainable future for the nation.

    Border dispute The pass was closed by China after the 1962 war and was reopened only after the Chinese president visited India in 2003.

     

    How has it been at the centre stage of India-China disputes?

    • Sino-Indian War: In 1962, Nathu La pass was a battleground between the Indian and Chinese armies during the Sino-Indian War. The conflict resulted in casualties on both sides, with China ultimately capturing the pass.
    • Skirmishes in 1967: In 1967, there were several minor skirmishes between the Indian and Chinese armies near Nathu La pass. The conflict was resolved through diplomatic negotiations.
    • Standoff in 2017: In 2017, there was a 73-day-long standoff between the Indian and Chinese armies near the Doklam plateau, which is close to Nathu La pass. The dispute was over the construction of a road by China in the disputed area. The standoff ended with both sides agreeing to disengage.

  • States demand that ‘Lightning’ be declared a Natural Disaster

    Central idea: A few states have requested lightning to be declared a natural disaster due to the high number of deaths caused by it in the country.

    Why discuss this?

    • Around 2,500 people die every year due to lightning.
    • Present norms consider cyclones, droughts, earthquakes, fires, floods, tsunamis, hailstorms, landslides, avalanches, cloudbursts, pest attacks, frost, and cold waves as disasters covered under the State Disaster Response Fund.
    • Deliberations are necessary as it is a policy issue.

    What is lightning?

    • Scientifically, lightning is a rapid and massive discharge of electricity in the atmosphere some of which is directed towards earth.
    • The discharges are generated in giant moisture-bearing clouds that are 10-12 km tall.
    • The base of these clouds typically lie within 1-2 km of the Earth’s surface, while the top is 12-13 km away.
    • Temperatures in the top of these clouds are in the range of –35° to –45°C.

    Its formation

    • As water vapour moves upward in the cloud, the falling temperature causes it to condense.
    • As they move to temperatures below 0°C, the water droplets change into small ice crystals.
    • They continue to move up, gathering mass until they are so heavy that they start to fall to Earth.
    • This leads to a system in which, simultaneously, smaller ice crystals are moving up and bigger crystals are coming down.
    • Collisions follow and trigger the release of electrons, a process that is very similar to the generation of sparks of electricity.
    • As the moving free electrons cause more collisions and more electrons, a chain reaction ensues.
    • This process results in a situation in which the top layer of the cloud gets positively charged, while the middle layer is negatively charged.
    • The electrical potential difference between the two layers is huge, of the order of a billion to 10 billion volts.
    • In very little time, a massive current, of the order of 100,000 to a million amperes, starts to flow between the layers.

    Types of lightning

    • Broadly, there are three forms of lightning:
    1. Inter-cloud
    2. Intra-cloud
    3. Cloud-to-ground
    • It is the cloud-to-ground form of lightning that kills humans, as well as animals and livestock, and can substantially damage property.
    • While the Earth is a good conductor of electricity, it is electrically neutral.
    • However, in comparison to the middle layer of the cloud, it becomes positively charged.
    • As a result, about 15%-20% of the current gets directed towards the Earth as well.
    • It is this flow of current that results in damage to life and property on Earth.

    How intensely does it strike?

    • A typical lightning flash is about 300 million volts and30,000 amps.
    • To put it in perspective, household current is 120 volts and 15 amps.
    • A flash of lightning is enough to light a 100-watt incandescent bulb for about three months.

    Why does lightning kill so many people in India?

    • The reason for the high number of deaths is due to people being caught unawares and more than 70% of fatalities happened due to people standing under isolated tall trees.
    • About 25 per cent of the people were struck in the open.
    • Also, lightning is the direct promulgation of climate change extremities.

    Mitigating lightning incidents

    • Lightning is not classified as a natural disaster in India.
    • But recent efforts have resulted in the setting up of an early warning system that is already saving many lives.
    • More than 96% of lightning deaths happen in rural areas.
    • As such, most of the mitigation and public awareness programmes need to focus on these communities.
    • Lightning protection devices are fairly unsophisticated and low-cost. Yet, their deployment in the rural areas, as of now, is extremely low.
    • States are being encouraged to prepare and implement lightning action plans, on the lines of heat action plans.
    • An international centre for excellence on lightning research to boost detection and early warning systems is also in the process of being set up.

  • G20: SUMups To Tackle Global Natural Disasters

    Central Idea

    • The concept of SUMups, a hypothetical bundling of complementary start-ups globally that work on some aspect of managing natural disasters. There are some of the innovative technologies developed by these start-ups and how they can be combined to develop more effective disaster management solutions.

    Background: The Rising Frequency and Impact of Natural Disasters Globally

    • Increasing Frequency and Severity of Natural Disasters: Globally, natural disasters have become increasingly common and the severity of their impact is worsening.
    • FAO Report: According to the FAO’s report, there were 360 natural disasters per year in the 2010s that resulted in at least 10 deaths, affected 100 or more people, led to homelessness or injury, and required a declaration of a state of countrywide emergency and an appeal for international assistance.
    • Comparison of Natural Disasters: This number is significantly higher than the 100 events recorded in the 1980s and the 90 events recorded in the 1970s.
    • Frequency of Climate, Weather, and Hydrology-related Disasters: Furthermore, climate, weather, and hydrology-related disasters are becoming more frequent, while geophysical and biological emergencies are not, with the exception of Covid-19.
    • Global Impact of Natural Disasters: The impact of these natural disasters is global, affecting countries across the world in various ways, including forest fires, heat and dust storms, and floods.
    • The Need to Improve Disaster Response and Mitigation Efforts: As a society, it is important to recognize that natural disasters will continue to pose a threat and we need to improve our ability to respond and mitigate their effects.
    • Measures Being Taken to Address the Issue of Natural Disasters: Fortunately, there are measures being taken to address this issue, including research into improving disaster response systems and the development of new technologies to aid in disaster preparedness and relief efforts.

    Disaster Prevention Technologies

    • The disaster prevention technologies developed by start-up
    • CERD-AR: CERD-AR developed an Augmented Reality (AR) application that gamifies the animations of disasters and provides disaster prevention drills to prepare people for evacuation and reaction in ultra-realistic settings.
    • A Palo Alto-based start-up One Concern: One Concern built a digital twin of the world by analyzing satellite images to predict natural disasters. The platform combines Artificial Intelligence, Machine Learning (AI/ML), and supercomputers to develop seismic and flood technology for real-time prediction of flooding and assess the risk associated with various events.

    Emergency Response and Reconstruction Technologies

    • Garuda Aerospace: Garuda Aerospace deployed drones in Turkey for surveillance in the affected earthquake areas to identify trapped victims.
    • HW Design Labs: HW Design Labs developed IoT innovations that support disaster response teams in planning their operations effectively through deep penetrating ground sensing radars, wireless connectivity solutions, advanced tracking, and navigation services.

    Emergency Communication Technologies

    • MyResQR: This start-up provides emergency communication between victims and stakeholders. The smart QR code manages information and triggers SOS during emergencies by enabling first responders like ambulance services, hospital staff, and other emergency response teams.

    Way Ahead

    • The SUMups represent an opportunity to combine innovative disaster management technologies from start-ups globally to address the Sustainable Development Goals for the whole world, such as building resilient infrastructure and zero hunger.

    Conclusion

    • The Startup20 Engagement Group of G20 can enable many such SUMups that can help deal with the increasing frequency, intensity, and complexity of natural disasters in the future. Sharing ideas and collaborating globally can help us all become better prepared and equipped to tackle these events. The article emphasizes that the sharing of ideas can be a powerful tool for solving complex problems, and the development of SUMups is a step in the right direction for improving disaster management worldwide.

  • ISRO releases Landslide Atlas of India

    landslide

    The Indian Space Research Organisation (ISRO) recently released the Landslide Atlas of India to identify landslide hotspots in the country.

    What are Landslides?

    • Landslides are natural disasters that occur in mountainous terrains where soil, rock, geology, and slope conditions are conducive.
    • A landslide is the sudden movement of rock, boulders, earth, or debris down a slope.
    • They can be triggered by natural causes such as heavy rainfall, earthquakes, snowmelting, and undercutting of slopes due to flooding.
    • They are extremely hazardous, posing a threat to human and animal lives, damaging property, roads, and bridges, disrupting communication lines, and snapping power lines.
    • Landslides are broadly classified based on the type of materials involved, the type of movement of the material, and the type of flow of the material.

    Why do they occur?

    • Landslides are natural disasters that occur mainly in mountainous terrains due to conducive conditions of soil, rock, geology, and slope.
    • Heavy rainfall, earthquakes, snow-melting, and undercutting of slopes due to flooding can trigger landslides.
    • Anthropogenic activities such as excavation, cutting of hills and trees, excessive infrastructure development, and overgrazing by cattle can also cause landslides.

    Factors contributing

    • The main factors that influence landslides include lithology, geological structures like faults, hill slopes, drainage, geomorphology, land use and land cover, soil texture and depth, and weathering of rocks.
    • Rainfall variability pattern is the single biggest cause for landslides in India, with the Himalayas and the Western Ghats remaining highly vulnerable.

    India’s vulnerability to landslides

    • India is considered among the top five landslide-prone countries globally, where at least one death per 100 sq. km is reported in a year due to a landslide event.
    • Approximately 12.6% of the country’s geographical land area (0.42 million sq km) is prone to landslides, with 66.5% of landslides reported from the North-western Himalayas, 18.8% from the North-eastern Himalayas, and 14.7% from the Western Ghats.

    Risks in specific states          

    • Mizoram recorded the highest number of landslide events in the past 25 years, with 12,385 events, of which 8,926 were recorded in 2017 alone.
    • Nagaland and Manipur also reported a high number of landslide events during the 2017 monsoon season.
    • Uttarakhand and Kerala reported the highest number of landslides, with Uttarakhand experiencing 11,219 events since 1998, and Kerala making inhabitants significantly vulnerable to fatalities, despite fewer events.

    Classification and Mapping of Landslides

    • Landslides are broadly classified based on the type of materials involved, type of movement, type of flow of the material, and whether they spread laterally.
    • The Landslide Atlas of India maps landslides mainly based on events and seasons.
    • The National Remote Sensing Centre (NRSC) used a landslide database created from 1998 to 2022 using aerial and high-resolution satellite images.
