ENVIRONMENT AND GEOGRAPHICAL VULNERABILITY TO NATURAL DISASTERS 

  • Rising Sea Levels: The Intergovernmental Panel on Climate Change (IPCC) reports a global sea level rise of 3.3 mm per year. Eg. Small island nations like Tuvalu face heightened risks of flooding and salinity intrusion. 
  • Deforestation and Landslides:  The World Bank estimates that 17% of the Amazon Rainforest has been lost in the last 50 years. Eg.The 2022 landslide in  Joshimath was exacerbated by deforestation, resulting in tragic consequences. 
  • Tectonic Activity and Earthquakes: Areas located along tectonic plate boundaries are at higher risk of earthquakes. The "Ring of Fire" around the Pacific Ocean is a seismic hotspot with frequent earthquake activity. Eg. The 2011 earthquake in Japan, situated on the Pacific Ring of Fire, caused a devastating tsunami and nuclear disaster. 
  • Climate Change and Extreme Weather Events:The National Oceanic and Atmospheric Administration (NOAA) notes an increase in the number of extreme weather events globally. 
  • Eg: The 2019-2020 Australian bushfires, exacerbated by prolonged heatwaves, showcased the link between climate change and extreme events. 

DIRECT AND INDIRECT IMPACT ON BIODIVERSITY  

Direct Impact  

  • Loss of Habitats :  Amazon rainforest fires have devastated the habitats , resulting in loss of numerous plants and animal species , especially endemic flora and fauna in regions.  
  • Coral bleaching :   Rising sea temperatures, linked to climate change, cause coral bleaching in the Great Barrier Reef. 
  • Threat to ecosystem resilience : Soil liquefaction and coastal subsidence disrupted habitats, leading to the loss of biodiversity and threatening ecosystem resilience. 
  • Mangrove Systems :   2004 Indian Ocean Tsunami highlighted the extensive damage to mangrove forests, seagrass beds, and coral reefs. 

Indirect Impact 

  • Nuclear Disaster :  Radioactive contamination from the  Fukushima nuclear meltdown affected soil, water sources, and marine sediments, influencing the health of terrestrial and aquatic organisms. 
  • Glacier Lake Outburst floods : Melting glaciers contribute to the formation of glacial lakes, can lead to sedimentation, altering river courses and affecting aquatic habitats downstream. 

SOCIO ECONOMIC IMPACTS OF NATURAL DISASTERS ON VULNERABLE COMMUNITIES 

  • Disproportionate Economic Loss: The World Bank notes that low-income countries suffer a disproportionate economic burden, with losses reaching up to several percentage points of their GDP. Example: The 2010 Haiti earthquake resulted in economic losses equivalent to 120% of the country's GDP, severely impacting an already impoverished population. 
  • Housing Vulnerability and Displacement:  The International Organization for Migration (IOM) reports that natural disasters displace an average of 26 million people annually, with vulnerable populations being the most affected. 

Eg: The 2013 Typhoon Haiyan in the Philippines led to the displacement of over four million people, predominantly from low-income coastal communities. 

  • Impact on Livelihoods and Agriculture:  The Food and Agriculture Organization (FAO) estimates that 22% of the total economic impact of natural disasters is absorbed by the agricultural sector. Eg: The 2015 earthquake in Nepal severely impacted rural communities, causing extensive damage to crops and livestock and jeopardizing food security. 
  • Health and Education Challenges:  UNICEF reports that natural disasters often result in the breakdown of essential services, leading to increased mortality rates and hindering access to education. Eg: The 2004 Indian Ocean Tsunami disrupted health services and education in affected regions, exacerbating vulnerabilities in already marginalized communities. 
  • Long-term Poverty Traps: The socio-economic impacts of natural disasters can create long-term poverty traps for vulnerable communities. Eg.  Research published in the World Development journal suggests that the economic recovery of vulnerable communities can take years or even decades. 

 CASE STUDY : JOSHIMATH LAND SUBSIDENCE IN UTTARAKHAND 

Joshimath, located in Seismic Zone V is prone to earthquakes , gradual weathering and water percolation. However subsidence  might have been triggered by the reactivation of a geographic fault where the Indian Plate has pushed under the Eurasian Plate along the Himalayas. Anthropogenic factors like  Tapovan Vishnugad Hydropower , widening of Char Dham Project ,  rampant tourism , unplanned urbanization , water withdrawals and  absence of proper drainage  have contributed to disaster in 2022. 

CHALLENGES IN REBUILDING AND SUSTAINABLE DEVELOPMENT POST NATURAL DISASTERS IN INDIA 

  • Infrastructure Deficiencies: The National Disaster Management Authority (NDMA) reports that inadequate infrastructure hampers rapid response and recovery efforts.Eg : Cyclone Fani in 2019 exposed vulnerabilities in the infrastructure of coastal areas in Odisha, hindering swift recovery. 
  • Urban Planning and Informal Settlements:  Rapid urbanization and informal settlements in India contribute to challenges in post-disaster rebuilding.Eg.The 2023 Nepal earthquake highlighted issues in urban planning, with informal settlements facing severe damage and slow reconstruction. 
  • Population Density and Resettlement: High population density complicates resettlement efforts post-disaster. Eg : The 2013 Uttarakhand floods led to challenges in relocating affected populations due to limited available land and resources. 
  • Environmental Degradation and Climate Change:  The Ministry of Environment, Forest and Climate Change (MoEFCC) recognizes the impact of climate change on the frequency of extreme weather events. Example: The recurring floods in Assam showcase the compounding challenges of rebuilding in the face of changing climate patterns. 
  • Coordination and Governance: Poor coordination between the state government, military, and disaster response agencies led to delays in reaching affected areas and providing essential aid. Eg. Bengaluru floods  

GLOBAL INITIATIVES FOR DISASTER MITIGATION  

  • Sendai Framework :  It  is the successor instrument to the Hyogo Framework for Action (HFA). It aims to guide the multi hazard management of disaster risk in development at all levels as well as within and across all sectors. 
  • The Climate Risk and Early Warning Systems (CREWS): The  Climate Risk and Early Warning Systems (CREWS) is an initiative to saves lives, assets and livelihoods through increased access to early weather warnings and risk information for people in Least Developed Countries (LDCs) and Small Island Developing States (SIDS). 
  • Green  Climate Fund : It provides an overview of country needs and evidence-based programming experiences in the relevant sector. 

INDIA INITIATIVES  

  • Coalition for Disaster Resilient Infrastructure Society (CDRIS): It aims to increase the resilience of infrastructure systems to climate and disaster risks, thereby ensuring sustainable development. 
  • National Disaster Management Plan (NDMP): It lays down policies, plans and guidelines for Disaster Management to ensure timely and effective response to disasters. 

CONCLUSION 

India faces a complex web of challenges in the aftermath of natural disasters, exacerbated by infrastructure deficiencies, urban planning issues, and the impact of climate change. The variety of  disasters highlights the intersection of natural and anthropogenic factors. While global initiatives like the Sendai Framework and the Climate Risk and Early Warning Systems provide a broader framework for disaster mitigation, India's National Disaster Management Plan and the Coalition for Disaster Resilient Infrastructure Society are crucial domestic steps toward enhancing resilience. Sustainable development hinges on coordinated efforts, innovative strategies, and a proactive approach to mitigate the socio-economic and environmental impacts of natural disasters in India.

News in Brief

GLOBAL TIGER NUMBERS ARE RISING


Why in news :  Countries have submitted tiger population numbers from 2010-2022 to the Global Tiger Recovery Program (GTRP) and United Nations Convention on International Trade in Endangered Species (CITES) under GTRP 2.0 which aims to pave the way for tiger conservation from 2023-2034. 

About :  

KEY FINDINGS  

  • Wild tiger status is good in South Asia and Russia, but the picture in Southeast Asia is grim 
  • There has been an overall increase in the tiger population by 60 per cent, taking the number to 5,870. 
  • Countries like Bhutan, Myanmar, Cambodia, Lao-PDR and Vietnam showed decline in tiger populations, making the situation “grim” in the Tiger Range Countries (TRCs) of Southeast Asia. 
  • Success of countries in South Asia like Bangladesh, Bhutan, India and Nepal including China and Russia in North East Asia is attributed to effective measures taken for habitat conservation and protection.  
  • Nepal has tripled the tiger population. 

CAUSE FOR DECLINE IN NUMBER OF TIGERS 

  • Invasive Species:  Proliferation of invasive species like Lantana camara in Indian forests has led to habitat degradation, reducing the abundance of ungulates that tigers depend on for sustenance. 
  • Man-Animal Conflict: Sundarbans in West Bengal witness frequent man-tiger conflicts due to the close proximity of human settlements to tiger habitats, resulting in fatalities on both sides. 
  • Infrastructure Development: The expansion of highways through wildlife corridors in central India, like the Pench-Kanha corridor, disrupts tiger migration routes, isolating populations and hindering genetic diversity. 
  • Disease: Outbreak of Canine distemper virus in the Sariska Tiger Reserve in Rajasthan led to the death of several tigers, highlighting the vulnerability of these apex predators to diseases. 
  • Poaching: The arrest of poachers in the Simlipal Tiger Reserve in Odisha in 2020, with seized tiger bones and skins, underscores the persistent menace of poaching even in well-protected reserves. 
  • Insufficient Prey: Some tiger reserves suffer from an inadequate prey base, jeopardizing the sustainability of tiger populations. Example: The Palamau Tiger Reserve in Jharkhand faces a challenge in maintaining viable tiger populations due to a decline in prey species, emphasizing the need for ecological balance in protected areas. 

GLOBAL INITIATIVES 

  • ST. PETERSBURG DECLARATION ( 2010 ) :  It brought together world leaders to endorse the Global Tiger Recovery Program (GTRP), which aimed to double tiger populations by 2022. 
  • GLOBAL TIGER INITIATIVE ( 2008 ) : It fostered collaboration among governments, NGOs, and international organizations to support tiger conservation efforts. 
  •  CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES  ( CITES ): CITES regulates the trade of tiger parts and products, aiming to eliminate illegal wildlife trade and ensure the legal and sustainable sourcing of tiger specimens.  

INDIAN INITIATIVES 

  • Project Tiger 
  • National Tiger Conservation Authority 
  • Tiger Census in India 
  • Wild Life (Protection) Amendment Act, 2022 

CONCLUSION 

While the global rise in tiger populations is encouraging, the pressing issues confronting Southeast Asian tigers necessitate urgent attention and thorough conservation measures. The coordinated endeavors of nations, underpinned by impactful policies and consistent resources, are crucial to guarantee the ongoing resurgence and welfare of this iconic species.

News in Brief

THOUSANDS OF EARTHQUAKE ROCK ICELAND


Why in news :   Recently , Iceland has declared a state of emergency following a series of 800 earthquakes that struck the southwestern Reykjanes peninsula in less than 14 hours. 

About :  

  • Around 1,400 earthquakes occurred in 24 hours and  24,000 have been recorded in the Reykjanes peninsula since late October.  
  • The most powerful of these quakes had a magnitude of 5.2, and hit about 40 km from Reykjavík, Iceland’s capital. 

WHAT IS HAPPENING TO ICELAND ? 

  • Iceland is located on the Mid-Atlantic Ridge, technically the longest mountain range in the world, but on the floor of the Atlantic Ocean.  
  • The ridge separates the Eurasian and North American tectonic plates — making it a hotbed of seismic activity. 

HOW CAN EARTHQUAKE SWARMS BE PORTENTS FOR VOLCANIC ACTIVITY ? 

  • Formation of Magma: Deep beneath the Earth's surface, the intense heat initiates the process of rock melting, giving rise to magma. This viscous, flowing substance is lighter than solid rock, setting the stage for geological activity. 
  • Magma Chambers and Underground Trapping: The upward movement of magma leads to its accumulation in underground chambers. These reservoirs, situated deep within the Earth, act as storage for the molten substance, creating a dynamic geological environment. 
  •  Volcanic Eruptions: While most magma remains trapped, a fraction finds its way to the surface through vents and fissures, resulting in volcanic eruptions. This explosive release of magma has significant geological consequences and is a key driver of Earth's dynamic landscape. 
  •  Earthquake Swarms: The movement of magma in proximity to the Earth's surface exerts force on surrounding rocks, often triggering earthquake swarms. These seismic events are symptomatic of the geological activity occurring beneath the Earth's crust. 
  • Surface Proximity and Eruption Likelihood: As magma moves closer to the Earth's surface, the likelihood of an eruption increases. The proximity to the surface is a critical factor influencing the eruption potential, with the escalating risk often accompanied by more frequent earthquake swarms. 

HOW MANY ACTIVE VOLCANOES DOES ICELAND CURRENTLY HAVE ? 

  • Iceland has  33 active volcanoes which have erupted over 180 times in the past 1,000 years. 
  • One of Iceland’s most famous volcanoes is Eyjafjallajökull. 
  • Other famous volcanoes include Hekla, Grímsvötn, Hóluhraun, and Litli-Hrútur (part of the Fagradalsfjall system).

Case Study of the Day

INVASIVE TREE SPECIES DEGRADING BANNI GRASSLANDS


  • Prosopis juliflora — a non-native and invasive tree species — has encroached over half Banni, one of Asia’s largest grasslands in Gujarat. The tree is harmful to ecology; yet, local communities have over time grown dependent on it for livelihood by, for example, making charcoal. 
  •  It has  depleted groundwater availability; increased soil salinity; and makes the grassland more susceptible to wildfires. The invasion has also posed a threat for habitat specialist species such as the desert fox, Houbara bustard and spiny-tailed lizard that have evolved to life in grasslands over centuries. 
  • Study found that mechanical removal of Prosopis “significantly increased native grassland plant diversity.”
