What is the Waqf Bill recently passed by the parliament? What would be its implications on the Indian Society?

 Why is it in the news?

1. The Rajya Sabha passed the Waqf (Amendment Bill) on April 4th 2025. The bill was supported by 128 votes against 95 votes of the opposition parties. The Lok Sabha had earlier passed the bill with 288 votes against 232 votes. Once the President gives assent to the bill, it will become an Act. 

2. The bill was introduced last year but on account of vociferous protests  by opposition parties,  it was referred to a joint parliamentary committee chaired by BJP MP Jagdambika Pal. The report was laid before both Houses on February 13th 2025.

3. Infuriated with the passage of Waqf Bill from both Houses of the Parliament, Congress MP Mohammad Javed, AIMIM MP Assaduddin Owaise, MLA Amanatullah Khan and NGO Association for protection of civil rights have filed separate petition before the Supreme Court, contending that the proposed legislation infringes upon constitutionally guaranteed right to religious freedom and property. 






What is Waqf?

1. In Islamic law, Waqf refers to movable as well as movable property dedicated in the name of Allah for religious or charitable purposes. Proceeds from such properties are to be used for the upkeep of Mosques, Dargah, Khanquah, Madrasas, Maktabs and other educational institutions. The funds from Waqf property are to be utilised for supporting the poor, needy and destitute. These are also meant to provide scholarships to meritorious students to get higher education. 

2. Once designated as Waqf, the property becomes inalienable. It means that the waqf property cannot be sold, inherited or gifted. The Waqf Act 1995 and amendments in 2013 created the legal framework for managing Waqf properties and established state Waqf boards. 


Why did the Government bring the Waqf bill?

1. The Government of India introduced the Waqf (Amendment Bill) in Parliament to address long standing issues in the management and regulation of Waqf properties. The new bill is named the Unified Waqf Management, Empowerment, Efficiency and Development (UMEED) Act. The Government contended that the Waqf Act of 1995 had become outdated and riddled with inefficiencies. For example, the Sachar Committee Report, 2006 highlighted the mismanagement of Waqf property, alleging that the Waqf properties worth 6000 crore generated a mere 163 crore annually due to encroachments, illegal sales and poor oversight by Waqf Boards. 

2. It aimed to enhance transparency, efficiency and inclusivity. The primary reason for bringing the waqf bill was to remove inefficiencies, corruption and legal ambiguities in the existing Waqf Act of 1995. The Government wanted reforms in the administration of the Waqf properties so that there should be better dispute resolution mechanisms, use of technology for property management and improved governance of Waqf Boards.  

3. Government also aimed at ensuring better representation in the Waqf Boards by including diverse Muslim sects and women and introducing provisions like mandatory registration of Waqf properties on a centralised portal and auditing these properties and profits accrued from them. Thus, the government wanted to include marginalised Muslim communities in the administration of Waqf boards. The government also aimed at uplifting Muslim communities economically and socially, particularly widows and divorced women through better management of Waqf assets. Thus, the new Waqf bill aims at eliminating inefficiencies and enhancing accountability. 


Judgements of the Supreme Court to push for reform in the Waqf Act 1995

The various judgments of the Supreme Court pushed the government to bring an amendment in the Waqf Act 1995. 

  • In the case of Rajasthan Waqf Board vs Union of India (2016), the Supreme Court questioned the unchecked authority of Waqf tribunals under Waqf Act 1995, whereby the decisions of Waqf tribunals were deemed to be final with no appeal to Civil Courts/High Courts. Thus, it suggested that there is a need for higher judicial oversight on the decision of Waqf tribunals because the finality clause infringes upon constitutional rights under article 14 (Right to equality) and article 21 (Due process of law). 

  • In the case of Karnataka Waqf Board vs Union of India (2018), the Supreme Court expressed dismay at the scale of encroachments on Waqf properties and failure of Waqf Boards to protect them. It also highlighted the mismanagement of the Waqf Board.  The Court also held that because of the mismanagement of Waqf properties, benefits from these properties do not reach to intended beneficiaries. 

  • In case of Waqf Board vs State of Maharashtra (2011), the Bombay High Court invalidated a Waqf Board claim over private land based on Waqf by user, ruling that long term use alone does not confer ownership without a valid deed. Thus, the court held that Waqf Boards must operate within the legal framework of property law, not religious custom alone. 

  • In the case of Karnataka Waqf Board vs State of Karnataka (2016), The Karnataka High Court lambasted the Board for colluding with encroachers and failing to maintain records. It recommended systematic reforms of Waqf Boards, citing lack of transparency and mired in corruption. It supported centralised management. 

  • In the case of UP Sunni Central Waqf Board vs State (2020), Allahabad High Court ruled that Waqf tribunals lacked jurisdiction over disputes involving non-waqf parties unless explicitly agreed, thereby advocating broader judicial access. Thus, the High Court pushed for integrating Waqf disputes into the mainstream judicial system to ensure fairness. 

  • In the case of Tamil Nadu Waqf Board vs State (2022), Madras High Court rejected the Tamil Nadu Waqf Board’s claim over an entire village (including 1500 year old Hindu Temple) based on flimsy ground, calling it an abuse of power. 

  • In the case of Delhi Waqf Board vs Union of India (2022), The court held that Delhi Waqf Board has failed to evict encroachers from 123 properties, including historical monuments. It ordered a detailed audit of the functioning of the Waqf Board and urged for its strict regulation.  

Thus, the different judgements of the Supreme Court and High Courts criticised Waqf Boards for mismanagement, encroachments, corruption and opec functioning. Courts often have urgent legislative and administrative intervention in the functioning of Waqf Boards. Secondly, courts have curtailed boards autonomy where it conflicted with constitutional norms or public interests. They rejected unchecked powers of Waqf tribunals. The judgements stressed upon reforms in Waqf boards entailing audits, proper documentation and judicial oversight. However, courts cautioned against excessive state control over the functioning of Waqf Boards, thereby infringing upon the constitutional rights under article 26 of our constitution.  



What are the important ingredients of Waqf bill?

1. The bill proposes sweeping reforms that significantly expands the government’s role in regulating Waqf properties and adjudicating disputes relating to them. It aims to modernise the governance of over 872000 properties, spanning 940000 acres of land valued at ₹1.2 trillion.  

2. Under the new amendment, only those who have practised Islam for at least 5 years can dedicate properties as Waqf. Thus, it alters the original law whereby any person regardless of religion could dedicate property as Waqf.  Critics point out that this provision is constitutionally suspect because once a person embraces Islam, he is entitled to all associated rights including the rights to religious dedication. This provision also violates the right to equality in article 14 of our constitution because it discriminates against  recent converts by selectively barring them from endowing property for religious purposes.  

3. The new Waqf bill also stipulates that all existing Waqf by user properties registered on or before the enactment of this law will retain their status unless they are disputed as Government land. It should be noted that Waqf by user is a doctrine in Islamic legal tradition that recognises properties as religious or charitable endowments based on uninterrupted communal use even in the absence of formal documentation. 

4. The Waqf Bill provides for the survey of properties by an officer above the rank of collector where the Government ownership is disputed. 

5. The bill provides for provision for the inclusion of non-Muslim in key Waqf institutions. It mandates that both the Central Waqf Council (22 members) and State Waqf Boards (11 members)  must have at least two non-Muslim members. It also removes the requirement that the Chief Executive Officer of a Waqf Board should be a Muslim. It also mandates that at least two Muslim women and representatives from Shia, Sunni, Bohra, Aghakhanis and other backward Muslim classes like Pasmanda in both bodies to ensure inclusivity. 

6. It also stipulates that there must be a State Government representative of the rank of Joint Secretary level to oversee the functioning of the Waqf Board. Critics argue that this provision is a direct infringement upon the fundamental rights of religious groups to administer their religious affairs under article 26, 29 and 30 our constitution. 

7. The bill provides for a centralised registration system for Waqf properties in order to enhance financial oversight. Muttawalis (custodians of Waqfs) will be required to upload property details within six months from the enactment of the law and all future registration must be routed exclusively through this portal to the respective Waqf Boards. 

8. The bill also seeks to repeal section 107 of the 1995 Act which had exempted Waqf properties from the applicability of the Limitation Act 1963. Critics argue that the removal of the Limitation Act would permit encroachers to claim ownership through adverse possession legitimising illegal occupation of Waqf land. 

9.  It ensures that a property can only be dedicated as Waqf after the owner settles inheritance claims, particularly safeguarding women’s rights under Islamic law. This prevents unilateral dedication that disenfranchises family members. 

10. It imposes strict penalties for mismanagement or failure to register properties.

11. State Government’s must appoint survey commissioners to identify and notify Waqf properties. Waqf Boards are required to publish details online, thereby enhancing the public access to information. 

12. District collectors or officers above their rank will survey and settle disputes over Waqf properties, thereby shifting power from tribunals to state administration. 

13. It removes the finality of Waqf tribunal decisions, allowing appeals to High Courts within 90 days. 

14. It empowers the Central Government to set detailed rules for Waqf management, registration, auditing and centralising oversight.

15. Waqf properties must undergo mutation, that is, ownership transfer under state revenue laws with proper records, ensuring legal clarity and reducing encroachments. 

16. Disputes involving government owned land claimed as Waqf will be adjudicated by senior officers above the rank of district collector and not by Waqf tribunals to resolve Waqf conflicts. 

Thus, the Waqf (Amendment Bill,2025) entails diverse representation, digital registration, audits and judicial oversight to enhance transparency, empowerment to marginalised Muslim Groups and Women and promote efficiency. 


Impacts of Waqf Amendment Bill,2025

1. It would lead to better transparency and accountability to Waqf Boards.

2. It would enhance public trust in Waqf institutions.

3. The bill would be able to curb corruption and misuse of official position in the Waqf.

4. It will increase powers of Waqf Boards, thereby resolving disputes swiftly. 

5. The bill would reduce  the power of Waqf Board authority and would enhance government oversight. 

6. The Bill would be seen as interference in religious autonomy by Muslim Community leaders. 

7. Because of encroachments of Waqf properties especially in urban areas, the surveying and digitalisation may reignite dispute over land ownership and so there would arise ampteen numbers of legal battles between individuals or institutions occupying Waqf lands and Waqf Boards. 

8. The Bill would bring more efficient management of Waqf properties , thereby enhancing their annual income. These incomes can be better utilised for the social, education and healthcare upliftment of Muslim communities.

9. The inclusion of non-Muslims and Government control in Waqf Board is seen by All India Muslim Personal Law Board as an erosion of religious autonomy guaranteed under article 26 our constitution, thereby fueling distrust and protest.  


Conclusion

1. The Waqf Amendment Bill aims at bringing transparency in the administration of the Waqf Boards. By auditing Waqf properties several encroached lands would be freed, which may be used for development of infrastructure like schools, hospitals. It is imperative to discourage fringe groups from using the law to target mosques or Dargah. It is also necessary to promote interfaith dialogue to address grievances over specific properties.

What is the new tariff policy of the United States announced on 2nd April 2025? How would it impact the world as well as the Indian economy?

Why is it in the news? 

1. On 2nd April 2025, The US President Donald Trump announced a comprehensive tariff policy. He imposed a baseline 10% duty on all imports from 5th April. This would be followed by individualised reciprocal tariff rates on nations with which the US has a high trade deficit. The increased tariff would be enforced from 9th April. 

2. The US tariffs on India were set at 26%, China 34%+ earlier 20%, totaling 54%, Vietnam 46%, Thailand 36%, Indonesia 32%, Laos 48%, Japan 24%, South Korea 25%, European Union 20%, UK 10% , Taiwan 32%. Thus, the main focus was on China and countries receiving significant Chinese investment called China + one nations acting as conduits for Chinese products into the western world. 

What is the tariff ?

1. Tariff is a tax imposed by the Government on imported goods and services. It makes foreign products more expensive. The purpose of tariffs is to protect domestic industries from cheap foreign goods, generate revenue for the Government, correct trade imbalances and retaliate against unfair trade practices. There are two types of tariffs 

  • Ad Valorem Tariff - It is charged at a percentage to the value of goods. For example, countries can charge a 10% tariff on the price of imported cars. If a car is valued 5 lakh, 10% tariff would be 50,000 realised by countries. 

  •  There are specific tariffs charged as a fixed amount per unit. For example, $100 tariffs on every imported smartphone. 


Reasons for the new tariff policy announced by the US

1. President Trump claimed that the US has reduced trade barriers for other countries for decades. On the other hand various countries imposed massive restrictions on American products. This resulted in the decimation for American industries. He cited the example of Detroit which was famous for car manufacturing. Its prime manufacturing position has slid with the passage of time. Most of the workers were thrown out of the job. 

2. President also accused several countries of manipulating their currencies, subsidising their exports, stealing intellectual property, adopting unfair rules and technical standards. 

3. The new tariff policy announced by the US was on account of huge trade deficits with countries like China, Mexico, European Union, Vietnam, Taiwan, Japan, South Korea, India, Canada, Malaysia and Israel.  See the graph below

4. USTR report (US Trade Representative) criticised India’s high applied tariffs on a wide range of goods like vegetable oil, apples, maize, motorcycles, natural rubber, automobiles , coffee, walnuts and alcoholic beverages. 

5. The US Government also reiterated that agriculture support programmes extended by India. Leads to distortion in the international markets. However, the Indian Government argued that US subsidies for farmers are much higher than those provided by India.

6. By increasing tariffs on imported goods into the US, the US government intends to increase the production of manufacturing industries, job opportunities to the youths and increasing the revenue of the Government. It also hopes that the increasing tariffs would have a salutary effect upon other countries of the world and so they would be forced to reduce tariffs on imported goods from the US, thereby, bringing a level playing field.  



Impact on global economy

1. The new tariff policy of the US led to significant global economic repercussions. China retaliated by imposing a 34% tariff on all US goods and restricting export of critical , rare earth elements.

2. Major US stock indices experienced declines of nearly 3% reflecting investor concern about a potential global recession. 

3. European and Asian markets also saw substantial drops with fears of escalating trade wars and economic instability.  

4. Higher tariffs will raise  the cost of imported goods like electronics, clothing and machinery in the US. It is estimated that $3800 would be added as expenses to each household.

5. The IMF's 3.3% global growth projection for 2025 is likely to be revised downward. Critics also point out that there is a chance of global recession on account of trade disruption and reduced economic activity. The developed countries like the European Union and Japan may see GDP shrink by 1-2% because of their heavy reliance on exports to the US. 

Similarly, export-dependent countries like Vietnam, Thailand, Mexico may experience sharper declines because of the heavy tariff duty by the US on their goods. 

6. Emerging markets like India, Mexico, Vietnam, Thailand may see capital outflows, thereby weakening currencies of respective countries.

7. Countries facing high US tariffs may diversify their  exports. This redirection of trade would benefit Africa, Latin America, South Eastern Asia, India. 

8. The high tariffs of the US may push for regionalisation, instead of globalisation. Countries would seek formation of regional blocks to reduce reliance on the US market. For example, India may shift its focus upon the European Union for its export instead of the US.  

9. If nations take recourse to retaliatory measures, it is apprehended that there would be trade wars among nations, resulting in shrinking of global GDP by 1-2% annually. Small countries like Singapore, Ireland, Thailand, Vietnam, Bangladesh would suffer the most. 

10. Economic friction may exacerbate US-China rivalry and would push neutral countries to pick sides, complicating multilateral cooperation on issues like climate change.  

11. Thousands of people gathered in different cities of the US and Europe to protest against the reciprocal tariff announced by President Trump, alleging that he was pushing them into a global recession. Stock exchanges of the US, Europe, Asia and India felt the brunt of  the new tariff policy of the US and the share market crashed. Economists fear that the new tariff policy would herald recession worldwide. 


Impact on India

1. It is estimated that the imposition of higher reciprocal tariffs by the United States on several Asian countries like China, Vietnam, Taiwan, Thailand and Bangladesh presents an opportunity for India to strengthen its position in global trade and manufacturing. 

2. Because of the high rates of tariffs on China and China + 1 countries, India has advantage in several key sectors like textiles and garments. The apparel sector of India would get a boost in the US market because the major competing countries like China, Bangladesh, Vietnam, Cambodia have been slapped with higher reciprocal tariffs by the US. Similarly, higher tariffs on Vietnam may boost Indian smartphones and solar module exports to the US. While there would be an adverse impact upon gems and jewellery. Since, import tariffs in the US may go to 20% from the current 0% on loose diamonds and 5.5% - 7% on gold jewellery. It should be noted that the US is India's largest jewellery export market, accounting for almost 30% of the share. 

3. High tariffs by the US on Indian exports would have a far reaching impact upon gems, jewelleries, smart phones, solar photovoltaic modules and auto components. The Trump Government already imposed a 25% tariff on steel, aluminium and automobiles in March and so, these sectors will also be affected. However, certain critical minerals, energy products, pharmaceuticals and bullions were exempted from US tariffs and so these Indian products would witness enhanced export from India to the US. That’s why the share of the pharmaceuticals increased to 3% just after the announcement of the US new tariff policy.  Export of generic drugs and antibiotics and along with certain petroleum oils stand to benefit from the exemption.  

4. However, discussions are going on between India and the US for the swift conclusion of a mutually beneficial multi-sectoral bilateral trade agreement encompassing a wide range of issues of mutual interest. The ongoing talks are focused on enabling both nations to expand trade, investment and technology. It aims at enhancing the trade volume from $190 billion to $500 billion by 2030.  

5. Experts are of the view that the enhanced US tariffs on India would reduce India’s GDP growth by 0.6% points. Sectors like metals, chemicals, jewellery, automobiles and food items would be highly affected. 


Ways out for India

1. Diversification of Indian exports

  • India should reduce dependence on the US for major exports by boosting trade with southeast Asia, Africa and the middle east. It should be noted that the US is the largest trading partner of India. 

  • India should make free trade agreements with the EU, the UK and Australia to offset US losses. The India-EU free trade agreement can open a $500 billion market for Indian goods. 

2. India should accelerate efforts to substitute imports and build self- reliance in tariff hit sectors like electronics and autos. Incentives for local manufacturing can offset higher US import cost, thereby, creating jobs. India should focus on value addition. Instead of raw material exports, finished products should be exported. India should focus on high value exports like electronics, semiconductors, green tech and biotech to reduce over dependence on traditional exports like textiles and gems. 

3. India should use tariff exemptions on energy commodities like oil and gas to keep production cost low in order to support industrial competitiveness.  

4. India should challenge discriminatory tariffs in the world trade organisation if it is treated unfairly compared with other countries. 

5. India should deepen its political and economic ties with the Indian Ocean Rim Association (IORA) to offset its losses of exports to the US on account of high tariffs. 

6. India should emphasise  its role as a counterweight to China in the Indo-Pacific by aligning with the US Geo-political interest to gain favourable trade terms. The bilateral trade agreement between India and the US should be finalised to achieve the target of $5 billion trade by 2030. It should also negotiate to lower tariffs or exemptions for key sectors like electronics, gems, jewellery. India should also offer reciprocal concessions to the US imported goods into India.  



Conclusion

The US tariff policy would destabilise the world economy by fracturing trade networks bringing protectionism and reducing globalisation, inflating cost and triggering a potential recession. Critics point out that the new tariff policy of the US would protect American industries, provide jobs to youths, increase the revenues of the US and reduce the trade deficits. However, higher prices, slower growth and market volatility would be witnessed in the global economy. In short, the world faces a turbulent economic landscape. This may mark a pivotal shift away from decades of trade liberalisation. The extent of damage depends upon the scale of retaliations by different countries and the ability of countries to adapt through diversification or negotiation.  India should therefore revive SAARC (South Asian Association of Regional Cooperation) and strengthen its economic and political ties with Indian Ocean Rim Association, IORA and EU to bolster its exports to offset losses on account of higher tariffs imposed by the US on Indian goods. 

To sum up, the new reciprocal tariff policy of the US will have a dampening effect on global trade. It would also usher in the collapse of economies of countries, like South Korea and Taiwan  which are highly dependent upon export driven growth.

What is a heatwave? How does it impact India in the pre-monsoon period of summer season?

 Why is it in the news? 

1. The India Meteorological Department has forecast above normal temperatures in most parts of the country this summer between April to June, including extended heatwave episodes that may last 10-11 days in central and eastern India, affecting Odisha, Jharkhand, Eastern UP in particular. 

2. The Director General of IMD said that above normal heatwave days are likely in Rajasthan, Gujarat, Haryana, Punjab, Madhya Pradesh, Maharashtra, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Odisha, Chhattisgarh,Telangana, Andhra Pradesh and Northern Parts of Karnataka. 

3. Heatwaves over these regions can last for 4-7 days but it is expected that these can prolong to 10-11 days over Odisha, Jharkhand, Eastern UP in this summer season. 

4. Heatwaves extending up to a  week could be experienced during April over eastern India mainly over Odisha. 

5. It is to be noted that heatwaves are common in the month of April over eastern India regions covering Jharkhand, Gangetic West Bengal, Vidarbha in Maharashtra and Gujarat and heatwaves continue for 1-3 days. But, this year it is expected that chances of extended heat waves will be in the month of April over the above regions.  

6. Thus, except West Peninsular India, some parts of East Central and East India, North eastern regions and J & K, major parts of India would be in the grip of heatwaves in the summer season between the months of April to June. 


What is the definition of heatwave and severe heatwave in India? 

1. When the maximum temperature exceeds at a particular place between 4.5°C to 6.4°C above the normal temperature for two consecutive days. Or when the maximum temperature reaches at least 40°C in plains, 37° C in coastal areas and 30°C in hilly regions for two consecutive days, it is called a heatwave. 

2. When the maximum temperature is increased to 6.5° C or more above the normal temperature of that region. Or if the maximum temperature exceeds 47°C in the plains, which persists for two consecutive days, it is called a severe heatwave. 

3. For example, If the normal maximum temperature in Delhi for the month of April is 37°C, if the temperature on two consecutive days is recorded 42°C, it would qualify as a heatwave. If the temperature increases to 44°C which persists for two consecutive days, it would be classified as a severe heatwave. 

Similarly, suppose the average annual temperature of Shimla, a hilly station, is recorded 27° C. If temperature increases 32° C, it would be called a heatwave. But, if the temperature goes to 34° C in Shimla for two days, it would be called severe heatwave. 

4. Heatwaves are more common in the northern, central and eastern parts of India. The most affected states from heat waves in India are Rajasthan, Uttar Pradesh, Madhya Pradesh, Haryana, Punjab, Odisha, Jharkhand, Chhattisgarh, West Bengal, Telangana, Vidarbha in Maharashtra, Eastern Gujarat and Andhra Pradesh. 


Increasing trends of heatwaves in India 

1. It has been found that instances of heatwaves in the central, north west and south east region of the country had been growing at the rate of about 3 heatwave days per decade since 2000. 

2.The year 2024 saw a total of 554 heatwave days across the country , that is,  a sum of heatwave days in all states. 

Thus, except Nagaland, Manipur, Mizoram and Tripura, almost the entire country experienced heatwaves.

3. It has also been found that there was a steady rise in the long duration heatwaves, sometimes going for 15 days at a stretch. The prolongation of heatwaves has a significant adverse impact on ecosystems, agriculture and public health. 


What are the causes for the heatwaves and severe heatwaves in India? 

Heatwaves in India are caused by the interaction between atmospheric high pressure systems, geographical features, climate change and human activities.  

1. Meteorological factor 

  • Northern India is situated in the subtropical high pressure belt of 30° N of latitude. In the summer season the high pressure belt shifts further northward, covering northern and western India. 

Air rises near the equator due to intense heating , moves poleward at high altitude and becomes cold. The cold air descends around 30°N and S latitude due to the coriolis effect. The sinking air from high altitudes suppresses cloud formation, resulting in clear skies and continued solar heating. The hot air near the ground is trapped. Uninterrupted sunlight heats the ground continuously during the day, causing temperature to rise sharply. High pressure systems usually remain stationary or move slowly. This stagnation traps warm air over a region for extended periods leading to the prolongation of the heatwaves. The lack of strong winds prevents the dispersion of hot air, thereby, intensifying local temperature. In normal conditions warm air rises, forming clouds and rain on account of convection. But a high pressure system inhibits convection, thereby, reducing rainfall and moisture. This leads to dry, hot and stable atmospheric conditions typical of heatwaves. 

  • Sometimes, high pressure systems get blocked by other weather patterns, causing them to persist for days, thereby, intensifying the heatwaves. The jet system naturally meanders due to temperature differences between polar and tropical air masses. Sometimes these waves amplify and become stationary, forming a blocking pattern. For example, in 2010, Russian heatwave was caused by blocking high pressure systems that remain stationary over western Russia leading to record breaking temperature and wildfires. Similarly, in India, the blocking system can delay monsoon onset, thereby, causing prolonged dry spells and heatwaves.     

  • Sometimes a heat dome is formed, thereby trapping hot air under a high pressure system. The dome acts like a lid, preventing cooler air from mixing in thereby, causing prolongation of heatwave conditions. High pressure pushes the clouds away from the dome. Hot air expands upward into the atmosphere but high pressure pushes warm air down, thereby, causing air compression leading to heat waves. 

  • Delayed or weak monsoon increases the duration of hot weather.

  • Weak western disturbances lead to reduced pre-monsoon showers, thereby, causing prolongation of heatwaves. 

  • The local wind called loo originates from the Thar desert. It blows from west to east. It is a dry wind and heats up to more than 50° C. 

  • Cities with concrete structure and limited vegetation trap more heat. 

2.Climate change 

  • Increased greenhouse gas emissions have raised global temperatures worldwide. Since India already has a high baseline temperature because of its tropical position, any further increase in temperature causes heat waves. In recent years, because of the climatic change and rising temperature, India is witnessing frequency of more heatwaves. 

  • Loss of tree cover and consequent deforestation further aggravates heat waves. 

  • High level of air pollution trap heat, thereby, exacerbating local temperatures. 

3.Anthropogenic Activities

  • Industrial emissions, burning of crop residues and vehicle emission further increase temperature. 

4.Atmospheric patterns

  • Warming of the Central Pacific Ocean and Indian ocean, thereby, causing El-Nino leads to hotter summers and weak monsoons in India. Weak monsoon causes prolongation of heatwaves in India. 

  • Hot winds from Arabian peninsula and central Asia often increase temperature in northwestern India. 



How does it impact India in the pre-monsoon period of summer season?

1.Heat waves may cause health issues like : 

  • Exhaustion

  • Heat Stroke

  • Dehydration

  • Increasing risk of the vulnerable groups like the elderly, children, outdoor workers and people with pre-existing conditions.

  • Increased mortality

  • Heat related complications

  • lMental health issued like stress, irritability and fatigue

2.It can cause following impacts on agriculture

  • Decreasing productivity of different crops

  • Livestock stress, reducing the productivity of cattle and therefore low production of milk. 

  • Increasing demand of water for irrigation

  • Severe impact upon Rabi crops 

3.Heat Waves can cause 

  • water scarcity

  • Food insecurity

  • Shortage of drinking water

4. Heat waves causes 

  • Reduced income of farmers

  • Reduced labour productivity

  • Increasing use of air conditioning and cooling system leading to power shortage

  • Migration of rural poor to urban areas in search of livelihood

5. Heatwaves leads to 

  • Wildfires 

  • loss of biodiversity

  • urban heat islands thereby, increasing the temperature in cities. 


How to mitigate the impact of heatwaves?

1.The impacts of heatwaves can be mitigated through following methods

  • Early warning system

  • Heat action plans that includes risk mapping, capacity, building and response protocols

  • Public awareness programme to educate public about heat related illness

  • Regular health check ups 

  • Promotion of the use of heat resistance materials for clothing and shelters

  • People should be exhorted to stay indoors during peak hours between 11 AM to 4 PM.

  • Establishment of cooling centres 

  • Medical preparedness 

  • Mobile medical units 

  • Urban  greening 

  • Cool roofs and walls

  • Ponds, lakes and fountains should be integrated in urban centres to moderate temperatures

  • Rescheduling of school, colleges. 

  • Rain water harvesting to increase ground water recharge to ensure water availability during heatwaves

  • Efficient use of water through drip irrigation

  • Setting up of water distribution points in public places

  • Promoting heat resilient crops 

  • Promoting agroforestry

  • Using organic mulch to maintain soil moisture and reduce surface temperature

  • Reducing carbon emission by promoting renewable energy and reducing fossil fuels to combat global warming. 

  • Investing in research for heat resisting crops, advanced cooling technologies and sustainable urban planning. 

  • Reducing urban heat islands by increasing greenbelts and reducing use of asphalt in cities. 


Conclusion

Heatwaves are natural calamities. They cannot be prevented. But through multifaceted approaches like public awareness, healthcare preparedness, urban planning, water management and long term climate action, their impact can be mitigated and precious lives can be saved. Several assessments have shown that the implementation of heat action plan has not been adequate in India while the administration has been more interested to implement short term measure such as making provision for drinking water in public places, creating cool shades for workers or preparing hospitals for heat related diseases, the long term interventions like greening of the cities, rejuvenation of water bodies, creation of parks or open spaces are being ignored. The approach of different governments is reactive rather than proactive, they react to a heatwave event when it occurs. They do not do enough to deal with the problem in a more comprehensive manner. It should be understood that the impacts of heatwaves can be largely managed if timely actions are initiated. 

 


What is Operation Sindoor?

  Why is it in the news? 1. India targeted nine locations in Pakistan and POK. The locations included Bahawalpur, Muridke, Sialkot, Muzaffar...
