Examine the the frequency & impacts of Cyclones over the Indian region?Disucss major steps taken by government of India?

-

 

 Studies show a decreasing trend in the frequency of formation of Cyclonic Storms over the Bay of Bengal and an increasing trend over the Arabian Sea, based on the data during 1965- 2020.However, the coastal vulnerability to the categories of Extremely Severe Cyclones’ or more continues over the Bay of Bengal region, as there is no significant trend in the frequency of Extremely Severe Cyclonic Storms (ESCS).

On the other hand, the increase in frequency over the Arabian Sea has not posed a corresponding increase in the coastal vulnerability along the west coast since most of such Cyclones forming over the Arabian Sea are making landfall over the coasts of Oman, Yemen etc and hence the threat to Gujarat & Maharashtra coasts remains same.on an average, out of 5 Cyclones developing over the North Indian Ocean (NIO) comprising Bay of Bengal and Arabian Sea, about 3 to 4 of them make landfall causing loss of life and property. Low lying coastal belts of West Bengal, Odisha, Andhra Pradesh and Tamil Nadu & Puducherry are more prone to the impact of these systems.greater vulnerability to tropical cyclone damage all over the world is mainly due to socio-economic and demographic factors. Improvements in warning systems and preparedness in disaster management remain critical to mitigate the loss of lives and, to some extent, loss of property.

Some of the studies have highlighted the importance of land-use planning, development of coastal districts and insurance measures, in addition to development of a vigilant disaster management system. Based on the Global best practices, the risk management of the Cyclones depends on several factors including

(i)          hazard & vulnerability analysis,

(ii)         (ii) preparedness & planning,

(iii)        iii) early warning services and

(iv)        (iv) prevention and mitigation.

The ‘early warning’ is a major component related to MoES/IMD targeting improved skill in monitoring and prediction and effective warning products generation. It is important to continuously upgrade all the components of early warning based on latest technology for effective management of Tropical Cyclones.

IMD has taken a number of steps in recent years to continuously enhance the capabilities in monitoring, numerical modeling and forecasting of the hazards associated with cyclones. Thus IMD has demonstrated its capability to provide early warning for Cyclones with high precision.

The Government of India has initiated the National Cyclone Risk Mitigation Project (NCRMP) with a view to address cyclone risks in the country. The overall objective of the Project is to undertake suitable structural and non-structural measures to mitigate the effects of cyclones in the coastal states and UTs of India. NDMA under the aegis of Ministry of Home Affairs (MHA) is implementing the Project in coordination with participating State Governments and the National Institute for Disaster Management (NIDM).The Project has identified 13 cyclone prone States and Union Territories (UTs), with varying levels of vulnerability.

 

The main objective of the NCRMP is to reduce vulnerability of coastal communities to cyclone and other hydro meteorological hazards through;

·         Improved early warning dissemination systems

·         Enhanced capacity of local communities to respond to disasters

·         Improved access to emergency shelter, evacuation, and protection against wind storms, flooding and storm surge in high areas

·         Strengthening DRM capacity at central, state and local levels in order to enable mainstreaming of risk mitigation measures into the overall development agenda

Discuss the impact of social media, overprotective parenting, and the decline of unsupervised outdoor play on children’s emotional well-being?

-
 The emotional well-being of children has been increasingly influenced by several modern factors, including social media, overprotective parenting, and the decline of unsupervised outdoor play. Each of these elements plays a role in shaping children's emotional health, and their combined effects can be complex. Here’s a closer look at how each factor impacts children: 1. Social Media Impact on Emotional Well-being: Increased Anxiety and Depression : Social media can expose children to idealized images and lifestyles, potentially leading to feelings of inadequacy and low self-esteem. For example, seeing peers portray seemingly perfect lives on platforms like Instagram or TikTok can make children feel like they don't measure up. Cyberbullying : Social media can be a medium for cyberbullying, which can lead to increased stress, anxiety, and depression. Victims of online bullying may experience emotional trauma and difficulty trusting others. Reduced Face-to-Face Interaction : Exce...

How political economy remains decisive in ensuring shared prosperity from technology.Explain?

-
  Political economy plays a crucial role in ensuring that technological advancements lead to shared prosperity rather than exacerbating inequalities. Here’s how: Regulation and Governance : Political decisions shape the regulatory framework that governs how technologies are developed, deployed, and used. Regulations can ensure fair competition, protect consumer rights, and promote inclusivity. For instance, laws can mandate accessibility standards for technology to ensure that all individuals benefit equally. Distribution of Benefits : The political economy determines how the economic benefits of technological progress are distributed. Policies such as progressive taxation or welfare programs can redistribute wealth and ensure that gains from technology benefit a broader segment of society, not just the wealthy or tech-savvy. Labor Market Dynamics : Technology often disrupts traditional industries and jobs. Political decisions influence how governments respond to these changes thro...
