NON COMMUNICABLE DISEASES
1. Context
2. Non-Communicable Diseases
- Non-communicable diseases (NCDs) are chronic medical conditions that are not caused by infectious agents and cannot be transmitted from person to person. These diseases typically have a long duration and progress slowly over time.
- NCDs are also referred to as chronic diseases and are often characterized by complex and multifactorial causes, including genetic, lifestyle, environmental, and behavioral factors.
- NCDs are a major global health concern, accounting for a significant proportion of morbidity, disability, and premature mortality worldwide.
- They impose a substantial burden on individuals, families, healthcare systems, and economies. Risk factors for NCDs include unhealthy diets, physical inactivity, tobacco use, harmful use of alcohol, and environmental factors such as air pollution.
- Prevention and control strategies for non-communicable diseases involve a combination of health promotion, early detection, access to quality healthcare services, lifestyle modifications, and effective management of existing conditions.
- Public health interventions aim to reduce NCD risk factors and promote healthy behaviors to mitigate the impact of these diseases on individuals and populations.
3. Findings of the Study on Non-communicable Diseases in India
- Diabetes and Prediabetes: India has 101 million people with diabetes and 136 million with prediabetes.
- High Blood Pressure: 315 million people in India were found to have high blood pressure.
- Obesity: Generalized Obesity: 254 million individuals in India were classified as obese. Abdominal Obesity: 351 million people in India had abdominal obesity.
- Hypercholesterolemia and High LDL Cholesterol: Hypercholesterolemia: 213 million individuals in India had high cholesterol levels. High LDL Cholesterol: 185 million people had elevated low-density lipoprotein (LDL) cholesterol.
- Study Details: The study was funded by the Indian Council of Medical Research and the Department of Health Research, Ministry of Health and Family Welfare. The Madras Diabetes Research Foundation coordinated the decade-long nationwide study. The findings of the study will be published in The Lancet Diabetes and Endocrinology journal.
4. Significance of the Study on Non-communicable Diseases in India
- Comprehensive Epidemiological Research: The study is the first comprehensive epidemiological research paper on non-communicable diseases in India. It includes participants from 31 states and some Union Territories, with a large sample size of 1,13,043 individuals.
- Increased Prevalence of NDCs: The study reveals that diabetes, hypertension, obesity, and dyslipidemia are more common in India than previously estimated. It highlights the urgent need for preventive measures and healthcare interventions to address the high prevalence of these diseases.
- Rural Diabetes Explosion: While urban areas currently have higher rates of metabolic NCDs, except for prediabetes, the study warns of an upcoming diabetes explosion in rural India if left unregulated.
- Inter-regional Variations: The study identifies variations in disease prevalence among different states and regions. Goa, Puducherry, and Kerala have the highest diabetes prevalence, while Sikkim has a high prevalence of Prediabetes, and Punjab has the highest hypertension rates.
- Implications for Policy: The findings highlight the need for state-specific policies and interventions to address the rising epidemic of metabolic NCDs in India. Urgent actions are required to stabilize diabetes rates in developed states and control the increasing prevalence in other regions.
- Study Details: The research used a cross-sectional, population-based survey of adults aged above 20 years. The study employed a stratified, multistage sampling design and is titled "Metabolic non-communicable health report of India- the ICMR-INDIAB National Cross-sectional Study.
5. Impact of Rising NCDs in India:
- Increased Burden of Diabetics and Hypertensive Individuals: Over the past four years, India has experienced a significant increase in the number of people affected by diabetes and hypertension. Generalized and abdominal obesity are contributing factors to this growing burden.
- Warning Signs for Future Health Issues: The study serves as an early warning, highlighting that if left uncontrolled, this population is at high risk of developing non-communicable diseases (NCDs) and life-altering medical conditions, including strokes.
- Dual Problem of Malnutrition and Obesity: Experts explain that India faces a dual problem of malnutrition and obesity. Although surplus food is available, factors such as exposure to fast food, lack of sleep, inadequate exercise, and increased stress contribute to the perfect environment for NCDs to thrive.
6. Addressing the Rising NCDs
- The solution to combating NCDs lies in adopting a wellness approach and embracing a lifestyle that includes a healthy diet and regular exercise.
- The Health Ministry recognizes four major NCDs Cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes.
- These diseases share common behavioral risk factors, including unhealthy diet, lack of physical activity, and tobacco and alcohol use.
- The Health Ministry has implemented Programs to strengthen health infrastructure and develop human resources.
- Health-promotion initiatives and awareness campaigns focus on prevention, early diagnosis, and ensuring appropriate referrals for NCDs.

FREE TRADE AGREEMENT
1. Context
2. About the Free Trade Agreement
- A Free Trade Agreement (FTA) is an agreement between two or more countries to reduce or eliminate barriers to trade, such as tariffs, quotas, and subsidies.
- FTAs can also include provisions on other issues, such as investment, intellectual property, and labour standards.
- The goal of an FTA is to promote trade and economic growth between the signatory countries.
- By reducing or eliminating trade barriers, FTAs can make it easier for businesses to export their goods and services to other countries, which can lead to increased production, employment, and innovation.
3. Types of Free Trade Agreement
- Bilateral Free Trade Agreement (BFTA) involves two countries, aiming to promote trade and eliminate tariffs on goods and services between them. It establishes a direct trade relationship, allowing for a more focused and tailored agreement between the two nations.
- Multilateral Free Trade Agreement (MFTA) Involving three or more countries, an MFTA seeks to create a comprehensive trade bloc, promoting economic integration on a larger scale. It requires coordination among multiple parties, addressing diverse economic interests and fostering a broader regional economic landscape.
- Regional Free Trade Agreement (RFTA) involves countries within a specific geographic region, aiming to enhance economic cooperation and integration within that particular area. It focuses on addressing regional economic challenges and fostering collaboration among neighbouring nations.
- Preferential Trade Agreement (PTA) involves a reciprocal reduction of tariffs and trade barriers between participating countries, granting preferential treatment to each other's goods and services. It allows countries to enjoy trading advantages with specific partners while maintaining autonomy in their trade policies with non-participating nations.
- Comprehensive Economic Partnership Agreement (CEPA) is a broad and advanced form of FTA that goes beyond traditional trade barriers, encompassing various economic aspects such as investment, intellectual property, and services. It aims for a more comprehensive economic partnership, encouraging deeper integration and collaboration between participating countries.
- Customs Union While not strictly an FTA, a Customs Union involves the elimination of tariffs among member countries and the establishment of a common external tariff against non-member nations. It goes beyond standard FTAs by harmonizing external trade policies, creating a unified approach to trade with the rest of the world.
- Free Trade Area (FTA) with Trade in Goods (TIG) and Trade in Services (TIS): Some FTAs specifically emphasize either trade in goods or trade in services, tailoring the agreement to the specific economic strengths and priorities of the participating countries. This approach allows nations to focus on areas where they have a comparative advantage, fostering specialization and efficiency.
4. India's Free Trade Agreements
India is a member of several free trade agreements (FTAs) and is currently negotiating others. India's FTAs have helped to reduce trade barriers and promote trade and economic growth. They have also helped to attract foreign investment and create jobs.
- The South Asian Free Trade Agreement (SAFTA) was signed in 1995 by the seven countries of the South Asian Association for Regional Cooperation (SAARC). SAFTA aims to reduce or eliminate tariffs on trade between the member countries.
- The India-Bangladesh FTA was signed in 2010 and came into force in 2011. It is a comprehensive FTA that covers goods, services, and investments.
- The India-Sri Lanka FTA was signed in 1999 and came into force in 2000. It is a comprehensive FTA that covers goods, services, and investments.
- The India-ASEAN Free Trade Agreement was signed in 2002 and came into force in 2010. It is a comprehensive FTA that covers goods, services, and investments.
- The India-Korea Comprehensive Economic Partnership Agreement (CEPA) was signed in 2010 and came into force in 2011. It is a comprehensive FTA that covers goods, services, and investments.
- The India-Japan Comprehensive Economic Partnership Agreement(CEPA) was signed in 2022 and came into effect in 2023. It is a comprehensive FTA that covers goods, services, and investments.
- The India-UAE Comprehensive Partnership Agreement (CEPA) was signed in 2022 and came into effect in 2022. It is a comprehensive FTA that covers goods, services, and investments.
- The India-Australia Economic Cooperation and Trade Agreement (ECTA) was signed in 2022 and came into effect in 2022. It is a comprehensive FTA that covers goods, services, and investments.
- The India-Malaysia Comprehensive Economic Cooperation Agreement (CECA) was signed in 2010 and aims to enhance economic ties by addressing trade in goods and services, as well as investment and other areas of economic cooperation.
- The India-Thailand Free Trade Agreement was signed in 2003 and focuses on reducing tariffs and promoting trade in goods and services between India and Thailand.
- The India-Singapore Comprehensive Economic Cooperation Agreement (CECA) has been operational since 2005, this agreement covers trade in goods and services, as well as investment and intellectual property.
- The India-Nepal Trade Treaty While not a comprehensive FTA, India and Nepal have a trade treaty that facilitates the exchange of goods between the two countries.
- The India-Chile Preferential Trade Agreement was signed in 2006 and aims to enhance economic cooperation and reduce tariffs on certain products traded between India and Chile.
5. India - UK Free Trade Agreement
5.1. Background
- Both countries have agreed to avoid sensitive issues in the negotiations.
- The interim (early harvest agreement) aims to achieve up to 65 per cent coverage for goods and up to 40 per cent coverage for services.
- By the time the final agreement is inked, the coverage for goods is expected to go up to "90 plus a percentage" of goods.
- India is also negotiating a similar early harvest agreement with Australia, which is supposed to set the stage for a long-pending Comprehensive Economic Cooperation Agreement that both countries have been pursuing for nearly a decade.
- While the commencement of negotiations does mark a step forward in the otherwise rigid stance adopted and when it comes to trade liberalisation, experts point to impediments and the potential for legal challenges going ahead.
5.2. GATT (General Agreement on Trade and Tariffs)
- The exception to the rule is full-scale FTAs, subject to some conditions.
- One rider, incorporated in Article XXIV.8 (b) of GATT, stipulates that a deal should aim to eliminate customs duties and other trade barriers on "Substantially all the trade" between the WTO member countries that are signatories to an FTA.
- For this Agreement, a free-trade area shall be understood to mean a group of two or more customs territories in which the duties and other restrictive regulations of commerce are eliminated on substantially all the trade between the constituent territories in products originating in such territories.
- It is often beneficial to negotiate the entire deal together, as an early harvest deal may reduce the incentive for one side to work towards a full FTA.
- These agreements are not just about goods and services but also issues like investment.
- If you are trying to weigh the costs and benefits, it is always better to have the larger picture in front of you.
- In the case of the early harvest agreement inked with Thailand, automobile industry associations had complained that relaxations extended to Bangkok in the early harvest had reduced the incentive for Thailand to work towards a full FTA.
- Early harvest agreements may serve the function of keeping trading partners interested as they promise some benefits without long delays, as India becomes known for long-drawn negotiations for FTAs.
- Government emphasis on interim agreements may be tactical so that a deal may be achieved with minimum commitments and would allow for contentious issues to be resolved later.

AIR QUALITY INDEX (AQI)
1. Context
2. The Air Quality Index (AQI)
The AQI is a colour-coded index launched under the Swachh Bharat campaign to simplify the understanding of pollution levels. It helps convey the condition of the air and guides appropriate measures based on the severity of pollution. The AQI consists of six categories, each with a corresponding colour code: 'Good' (0-50), 'Satisfactory' (51-100), 'Moderately Polluted' (101-200), 'Poor' (201-300), 'Very Poor' (301-400) and 'Severe' (401-500).
3. Calculation of AQI
- To calculate the AQI, a technical study was conducted by an expert group, including medical professionals, air quality experts, and academics.
- Various pollutants, such as PM10, PM2.5, Nitrogen Dioxide, Ozone, Carbon, and others, are measured.
- Each pollutant is assigned a weight based on its impact on human health.
- The composite air quality index is determined by combining these weights, simplifying multiple data points into a single number and colour to represent overall air quality.
- Monitoring stations across the country assess these pollutant levels.
4. Impact of Pollutants on Health
- Among the most harmful pollutants are fine particulate matter, such as PM2.5, which has a diameter smaller than 2.5 micrometres.
- PM2.5 particles can easily enter the circulatory system, bypassing the nose and throat.
- They are associated with respiratory problems and reduced visibility, posing health risks such as asthma, heart attacks, bronchitis, and other respiratory issues.
5. Influence on Government Policy
- Governments, especially in areas like Delhi, use the AQI to announce measures to combat air pollution.
- When the AQI in the National Capital Region (NCR) reaches the 'severe' category, Stage 4 of the Graded Response Action Plan (GRAP) is implemented.
- GRAP is designed for emergency measures to prevent further deterioration of air quality.
- Specific actions may include prohibiting the use of non-BS-VI-compliant diesel four-wheelers and restricting the entry of trucks into the city while allowing petrol cars to continue operating as usual.
6. Conclusion
The Air Quality Index is an essential tool that simplifies the understanding of air pollution, assesses its health impacts, and influences government policies and actions to combat deteriorating air quality. As Mumbai braces for worsening air quality, the AQI will continue to be a critical resource for both the government and the public.

H5N1
1. Context
2. Avian Influenza
- Avian Influenza, also known as Avian or Bird Flu, is a form of influenza caused by a virus found in birds.
- Avian Flu is similar to variants found in animals and humans – caused strains of influenza that have adapted to specific hosts.
3. Avian Influenza Type A viruses
- Type A viruses are classified based on two proteins on their surfaces – Hemagglutinin (HA) and Neuraminidase (NA). There are about 18 HA subtypes and 11 NA subtypes.
- Several combinations of these two proteins are possible e.g., H5N1, H7N2, H9N6, H17N10, H18N11, etc.
- All known subtypes of influenza A viruses can infect birds, except subtypes H17N10 and H18N11, which have only been found in bats.

4. Effect on Birds
- Although avian influenza has different subtypes, H5N1 is a highly pathogenic subtype that causes mortality in birds.
- Since 2022, the virus has infected over 100 million birds across the globe, resulting in the deaths of over 50 million and the culling of millions of poultry.
- Unlike previous outbreaks of highly pathogenic subtypes of avian influenza, H5N1 is heavily impacting wild bird species, including many which were on the verge of extinction.
- While it is difficult to ascertain how many wild birds have been affected by the virus, a significant impact has been seen in eagles, pelicans, geese, waterfowl, gulls, falcons, and shorebirds, in addition to the highest possible impact on poultry seen till date, at least in the U.S.
- The impact of H5N1 on wild bird populations has varied depending on several factors, such as the level of exposure, geographical locations, and migratory patterns of the affected species.
- High mortality in wild birds due to the virus could lead to significant ecological consequences, including the vulnerability of predators and alterations in species composition in affected ecosystems, and therefore a possible impact on biodiversity not just limited to avian species.
- It has raised concerns regarding the spread of the virus among critically endangered avian populations.
5. Spreading to animals
- The highly contagious H5N1 virus can also occasionally spill over from birds to animals through direct or indirect contact with infected birds or their droppings.
- Worryingly, there have been several reports on the spillover of H5N1 to mammals during the current outbreak from different countries, infecting species such as sea lions, minks, foxes, wild bears, and skunks, apart from domestic animals such as dogs and cats.
- In 2023 alone, H5N1 caused the deaths of over 3,000 sea lions in Peru. In a recent yet to be peer reviewed study, scientists found that the virus could efficiently spread between ferrets in the laboratory.
- The only known cases of the virus spreading between mammals were reported in minks that were raised in close confinement on a farm in Spain.
- The transmission of H5N1 from birds to mammals is rare, but when it does occur, it can be a cause for concern, as the virus could accumulate mutations and acquire the ability to potentially initiate human outbreaks.
- H5N1 has a high mortality rate of over 60% in humans and is primarily transmitted to humans through close contact with infected birds or animals, either through handling infected poultry or exposure to contaminated environments.
6. Enhanced Measures
- As the current H5N1 outbreak continues unabated with devastating impact on the avian population globally, and with significant ecological and economic consequences, the time has never been better to initiate efforts for preparedness towards building better, more efficient vaccines for avians and humans.
- Genomic surveillance should be done to map the continued evolution of the virus.
- Moreover, enhanced biosecurity measures are required to protect both animal and public health.

GRADED RESPONSE ACTION PLAN(GRAP)
1.Context
2.What is a Graded Response Action Plan (GRAP)
3.Has GRAP Helped?
- The biggest success of GRAP has been in fixing accountability and deadlines.
- For each action to be taken under a particular air quality category, executing agencies are marked.
- In a territory like Delhi, where a multiplicity of authorities has been a long-standing impediment to effective governance, this step made a crucial difference.
4.Measures that are taken in other states
- one criticism of the EPCA, as well as GRAP, has been the focus on Delhi. While other states have managed to delay several measures, citing a lack of resources, Delhi has always been the first to have stringent measures enforced.
- When the air quality shifts from poor to very poor, the measures listed under both sections have to be followed since the plan is incremental in naturality reaches the severe+ stage, GRAP talks about shutting down schools and implementing the odd-even road-space rationing scheme.
5.Actions under GRAP

STUBBLE BURNING
1. Context
2. What is Stubble?
Stubble refers to the leftover plant material, mainly crop residues, that remains in the field after the primary crop has been harvested. This includes the stems, leaves, and other organic material that is left behind.
Stubble burning is a common agricultural practice where farmers set fire to crop residues, such as straw and stubble, that remain in the field after the main crop (usually paddy or wheat) has been harvested. This practice is typically used as a quick and cost-effective method to clear the field for the next planting season. Stubble burning is particularly prevalent in regions with mechanized farming, where machines like combine harvesters leave behind a significant amount of crop residues.
3. Stubble burning contributes to air pollution
When stubble is burned, it releases a variety of pollutants into the air, including particulate matter, carbon monoxide, nitrogen oxides, and sulfur dioxide. These pollutants can cause several health problems, including respiratory problems, heart disease, and cancer.
Stubble burning is a major contributor to air pollution in many parts of the world. In India, for example, stubble burning is responsible for up to 30% of the air pollution in Delhi during the winter months.
- Stubble burning generates fine particulate matter (PM2.5 and PM10) that can penetrate deep into the respiratory system, leading to respiratory problems and reduced air quality.
- The combustion of stubble releases carbon monoxide, which can have adverse health effects when inhaled, particularly in enclosed spaces.
- Stubble burning produces Volatile Organic Compounds (VOCs), which can react with other pollutants in the atmosphere, contributing to the formation of ground-level ozone, a major air pollutant.
- Burning stubble emits greenhouse gases like carbon dioxide (CO2) and methane (CH4), contributing to climate change.
- The combustion of crop residues can release various hazardous chemicals and pollutants, further deteriorating air quality.
4. About the Central Scheme for the Promotion of Agricultural Mechanisation for In-Situ Management of Crop Residue
The Central Scheme on Promotion of Agricultural Mechanisation for In-Situ Management of Crop Residue (AMICMR) is a scheme launched by the Government of India to promote the use of in-situ techniques for managing crop residue. In-situ techniques are those that are used to manage crop residue on the field, rather than burning it. Examples of in-situ techniques include:
- Mulching is the practice of covering the soil with a layer of organic material, such as straw or leaves. This can help to suppress weeds, retain moisture, and improve soil health.
- Zero tillage is the practice of planting crops without tilling the soil. This can help to prevent soil erosion and retain moisture in the soil.
- Direct seeding is the practice of planting seeds directly into the soil, rather than transplanting seedlings. This can help to reduce soil disturbance and prevent the spread of weeds.
The AMICMR scheme provides financial assistance to farmers to purchase machinery that can be used for in-situ management of crop residue. The scheme also provides training and extension services to farmers on how to use these techniques.
The AMICMR scheme is a promising initiative that could help to reduce air pollution caused by stubble burning. However, the scheme needs to be scaled up and made more widely available to farmers to have a significant impact.
5. Conclusion
Stubble burning is a major contributor to air pollution in many parts of the world. However, there are several alternatives to stubble burning, such as in-situ management of crop residue. In-situ management of crop residue is a more sustainable way to manage stubble, as it does not release pollutants into the air and has several benefits for soil health and crop yields.
