Context
  • India faces a significant economic and health burden from dengue, exacerbated by limited success with current vector control methods.
  • Innovative approaches using the Wolbachia bacterium in mosquitoes have shown promise globally.
  • India, with no active Wolbachia program yet, could benefit from adopting these strategies to combat dengue and other mosquito-borne diseases.
Everything You Need To Know About

Dengue’s Economic and Health Impact

  • Economic Burden: Dengue imposes a significant economic burden in India, estimated at around ₹28,300 crore annually in direct costs.
  • The disease leads to the loss of approximately 5.68 lakh years of young life each year.

Current Vector Control Strategies

  • Modest Success: Existing methods, including insecticides and community education, have seen limited success.
  • Vaccine and Antiviral Agents: Clinical trials are ongoing for dengue vaccines, and effective antiviral agents remain undiscovered.

Innovative Vector Control Methods

  • Wolbachia Bacterium: Studied globally since 2009, Wolbachia, a bacterium found in many insects but not Aedes mosquitoes, shows promise.
  • Dual Relationship: Wolbachia exhibits mutualism by providing viral resistance and parasitism by reducing the insect’s lifespan and skewing populations towards females.
More About Wolbachia Bacterium:
  • Wolbachia bacteria are used in dengue control by infecting mosquitoes, particularly Aedes aegypti, which spread the virus.
  • Infected mosquitoes are less capable of transmitting dengue because Wolbachia inhibits the virus’s development.
  • When released into the wild, these mosquitoes mate with wild populations, spreading Wolbachia and reducing dengue transmission rates.
  • This approach has shown success in various trials, offering a promising, sustainable method to manage and reduce dengue outbreaks.

Field Trials and Strategies

  • Australia’s Approach: Used the wMel strain to promote viral resistance without shortening mosquito lifespan, leading to successful population replacement and near dengue elimination.
  • Singapore’s Approach: Implemented population suppression by releasing Wolbachia-infected males, reducing Aedes populations by 90% and dengue cases by 77%.
  • Indonesia Trial: A landmark trial showed a 77% reduction in dengue cases and an 86% reduction in hospitalizations in areas with wMel mosquito releases.

wMel Programs in India

  • Current Status: India has no active wMel release program. ICMR-VCRC is developing wMel Aedes strains and has reported finding Wolbachia naturally in Aedes in North East India.
  • Potential Benefits: The wMel strategy could reduce the burden of dengue, chikungunya, Zika, and other emerging infections, proving highly cost-effective.

Recommendations

  • Public Messaging: Effective communication about mosquito releases is crucial.
  • Learning from Global Experiences: Insights from other countries’ mosquito release programs can guide implementation in India.

(Source: Indian Express; Section: Explained; Page: 07)

Topic: GS3 Indian Economy
Context:
Retail food inflation dropped to 5.4% in July 2024 from 9.4% in June, primarily due to a high base effect from July 2023.

Analysis of News:       

Everything You Need To Know About

What is Inflation?

  • Inflation refers to the overall increase in the prices of goods and services, coupled with a decrease in people’s purchasing power.
  • This means that when inflation rises (without an equivalent rise in your income), you are able to buy fewer things than you could buy previously, or you have to pay more money for the same stuff now.
  • A “rising” inflation rate implies that the rate (at which the prices rise) itself is increasing.
  • For example, if the inflation rate was 1% in March, 2% in April, 4% in May, and 7% in June, it shows a continuous acceleration in the rate of price increases.

What are the Different Indices through Which Food Inflation is Measured in India?

  • Consumer Price Index (CPI):
  • CPI inflation, also known as retail inflation, is the rate at which the prices of goods and services that consumers buy for personal use increase over time.
  • It measures the change in the cost of a basket of goods and services that are typically purchased by households, including food, clothing, housing, transportation, and medical care, and are of four types:
  • CPI for Industrial Workers (IW).
  • CPI for Agricultural Labourer (AL).
  • CPI for Rural Labourer (RL).
  • CPI for Urban Non-Manual Employees (UNME).
  • Consumer Food Price Inflation (CFPI):
  • CFPI is a component of the broader Consumer Price Index (CPI), where the Reserve Bank of India (RBI) utilises the CPI-Combined (CPI-C) for this purpose.
  • CFPI monitors the price fluctuations of a particular selection of food items commonly consumed by households, including cereals, vegetables, fruits, dairy products, meat, and other essential food staples.
  • CFPI is a component of the broader Consumer Price Index (CPI), where the Reserve Bank of India (RBI) utilises the CPI-Combined (CPI-C) for this purpose.
  • The Wholesale Price Index (WPI):
  • It tracks changes in the prices of goods sold and traded in bulk by wholesale businesses to other businesses and it specifically focuses on goods, services are not part of it.
  • The WPI is utilized to monitor supply and demand dynamics in industries, manufacturing, and construction sectors.
  • Released monthly by the Economic Advisor in the Ministry of Commerce and Industry, the index measures the level of wholesale inflation in the economy based on the month-to-month increase in WPI, and it comprises various component
  • Primary articles, constituting 22.62% of the Wholesale Price Index (WPI), are divided into Food Articles and Non-Food Articles.
  • Food Articles encompass items like Cereals, Paddy, Wheat, Pulses, Vegetables, Fruits, Milk, Eggs, Meat, and Fish.
  • Non-Food Articles include Oil Seeds, Minerals, and Crude Petroleum.
  • Impact on Economy: Despite the decline, food inflation remains a significant concern, limiting household spending and preventing the Reserve Bank of India from reducing interest rates.
  • Monsoon Influence: The southwest monsoon revived after a weak start in June, leading to above-normal rainfall in July and August. This improved water availability has led to increased acreage for key crops like rice, pulses, maize, oilseeds, and sugarcane.
  • Global Food Prices: Global food prices have decreased since December 2022, helping to mitigate domestic inflation. Lower international prices for commodities like wheat make imports more feasible, potentially easing domestic prices.
  • Cautious Optimism: While the good monsoon and potential La Niña conditions are positive, the full impact on food inflation will only be clear after the upcoming harvests. Uncertainty remains, especially with the harvest still weeks away.
What are the Strategies that Need to be Adopted to Tackle Food Inflation in India?

Improved Supply Chain Management:

  • Strengthening logistics, storage facilities, and distribution networks can minimize wastage and ensure a consistent food supply, mitigating price fluctuations.
  • For example, the use of refrigerated trucks for transporting perishable goods ensures that they reach markets in optimal condition, reducing spoilage and increasing the availability of fresh produce.

Agricultural Productivity Enhancement:

  • Investments in agricultural infrastructure, technology, and research can boost crop yields, reducing production costs and stabilizing prices.
  • For example, implementing drip irrigation techniques has shown significant water savings and increased crop productivity in regions facing water scarcity.

Price Monitoring and Regulation:

  • Implementing mechanisms for regular monitoring of food prices and enforcing fair pricing practices can protect consumers from exploitation.
  • Examples like, setting maximum retail prices for essential food items can prevent retailers from overcharging consumers during times of scarcity or high demand.

Agricultural Diversification:

  • Encouraging farmers to cultivate a variety of crops can reduce the country’s dependence on specific commodities.
  • Initiatives like promoting the cultivation of pulses alongside traditional crops like rice and wheat can enhance soil fertilityreduce pest infestations, and provide farmers with alternative income sources.

Climate Resilience:

  • Adopting climate-smart agricultural practices, such as rainwater harvesting and crop rotation, can help mitigate the impact of climate change on food production.
  • For example, promoting the cultivation of drought-resistant crop varieties can safeguard against crop failures during periods of water scarcity or extreme weather events

Utilizing technology:

  • Devices like AmbiTag can prove advantageous in mitigating food wastage during transit.
  • It continuously records the temperature of its immediate surroundings from -40 to +80 degrees in any time zone for a full 90 days on a single charge.
  • It generates an alert when the temperature goes beyond a pre-set limit.
