Why in News? The innovative Steel Slag Road technology developed by the Central Road Research Institute (CRRI), New Delhi in collaboration with the Ministry of Steel and major steel manufacturing companies is making significant strides towards the 'Waste to Wealth' mission. This technology is revolutionizing road construction and addressing the environmental challenges of steel slag waste. What is Steel Slag Road Technology? About: Steel slag road technology is a novel method of using steel slag, the waste generated during steel production, to build more robust and more durable roads. The technology involves processing the steel slag to remove impurities and metal content and then using it as an aggregate for road base or sub-base layers. The processed steel slag has high strength, hardness, abrasion resistance, skid resistance, and drainage capacity, making it suitable for road construction. It facilitates the large-scale utilization of waste steel slag generated by steel plants, effectively managing the approximately 19 million tonnes of steel slag produced in India. Advantages: Eco-friendly Waste Utilization: By using waste steel slag in road construction, the technology offers an eco-friendly approach to managing industrial waste. This reduces the burden on landfills and minimizes the environmental impact associated with steel slag disposal. Cost-effective and Durable: Steel slag roads have proven to be cost-effective, as they are approximately 30% cheaper to construct compared to conventional paving methods. Furthermore, these roads exhibit exceptional durability and resist weather changes resulting in significantly reduced maintenance costs. Reduced Reliance on Natural Resources: Traditional road construction heavily relies on natural ballast and aggregates, depleting precious natural resources. The Steel Slag Road technology eliminates the need for natural materials, helping conserve valuable resources and preserve natural ecosystems. Addressing the Steel Slag Waste Challenge: India is the world's second-largest steel-producing country, generating around 19 million tonnes of steel slag as solid waste. This figure is projected to increase to a staggering 60 million tonnes by 2030, with each tonne of steel production resulting in about 200 kg of steel slag waste. The lack of efficient disposal methods has led to the accumulation of huge slag piles around steel plants, contributing to water, air, and land pollution. Successful Implementations: Surat's Technological Marvel: The first road constructed using the Steel Slag Road technology in Surat, Gujarat, has garnered recognition for its technological excellence. Border Roads Organization's Contribution: The technology's success extended to the India-China border, where the Border Roads Organization, along with CRRI and Tata Steel, constructed a steel slag road in Arunachal Pradesh. This project demonstrated the technology's suitability for challenging terrains and critical national infrastructure. Promoting Nationwide Adoption: The success of the Steel Slag Road technology has attracted the attention of various government agencies and ministries. In collaboration with the Ministry of Science and Technology and the Ministry of Road Transport and Highways, the Ministry of Steel is actively working to promote the widespread usage of this technology across the country. By fostering collaborative efforts, India aims to lead the way in sustainable road infrastructure development and achieve its 'Waste to Wealth' mission. Waste to Wealth Mission This mission will identify, develop, and deploy technologies to treat waste to generate energy, recycle materials, and extract worth. The Waste to Wealth Mission is one of the nine national missions of the Prime Minister’s Science, Technology, and Innovation Advisory Council (PM-STIAC). The mission will assist and augment the Swachh Bharat and Smart Cities projects to create circular economic models that are financially viable for waste management to streamline waste handling in the country. Agriculture Prev Next Tomatoes Price Volatility Tags: GS Paper - 3Food Security For Prelims: Tomato Mosaic Virus (ToMV) and the Cucumber Mosaic Virus (CMV), Inflation Rate For Mains: Food Inflation and issues, Impact of extreme weather conditions, Pest attacks, and viruses (ToMV and CMV) on tomato yields, Role of the Government in managing prices and stabilizing the market. Source: TH Why in News? Tomatoes, a staple vegetable in Indian households, have become a cause for concern due to their soaring prices. The sudden increase in tomato prices from ₹20 to ₹40 per kg in June 2022, reaching ₹100 per kg in July 2023, has raised questions about the reasons behind this price volatility. Despite the soaring prices, the inflation rate for tomatoes is surprisingly negative, creating a puzzling economic phenomenon known as #Tomato-nomics. Why are Tomato Prices High? Tomatoes Production in India: Tomato production is regionally concentrated in states like Andhra Pradesh, Madhya Pradesh, Karnataka, Odisha, and Gujarat, collectively accounting for approximately 50% of total production. India witnesses two main tomato crops annually - kharif and rabi. The Kharif crop is available from September, while the rabi crop hits the market between March and August. July-August is a lean production period for tomatoes as they fall between yields. Despite being one of the most cultivated vegetables, tomato production has been declining since its peak in 2019-20 at 21.187 million tonnes (MT). Reasons Behind the High Tomato Prices: Extreme Weather: Heatwaves and delayed monsoons in April and May led to pest attacks on tomato crops, affecting their quality and commercial realization. As a result, farmers received low prices for their produce in the months leading up to June. CMV and ToMV Virus: The recent decline in tomato crops and the surge in tomato prices in Maharashtra, Karnataka, and other South Indian states can be attributed to the infestation of two plant viruses: the Tomato Mosaic Virus (ToMV) and the Cucumber Mosaic Virus (CMV). These viruses have caused partial to complete crop losses in tomato plantations over the last three years. As both viruses have a broad host range and can lead to nearly 100% crop loss if not treated in time, they have significantly impacted tomato yields, resulting in a rise in tomato prices. Low Commercial Realization: Farmers faced the challenge of low commercial realization for their tomato crops in the months leading up to the price surge. Between December 2022 and April 2023, many farmers received prices as low as ₹6 to ₹11 per kg for their produce. This led to a situation where farmers had to sell their crops at unprofitable rates or even abandon their produce, resulting in a shortage of supply. Farmer Shifting from Tomato Production: The low prices received by farmers in the previous year led to a significant impact on cultivation patterns. Many farmers who contribute substantially to tomato supplies shifted their focus to cultivating other crops fetched higher prices in the market, motivating farmers to opt for alternative crops. This shift in cultivation resulted in reduced tomato production, further aggravating the supply crunch and contributing to the surge in prices. Supply Crunch: Inferior-quality tomatoes forced many farmers to sell at low prices or abandon their crops, resulting in a crunch in tomato supply. Incessant rains further impacted the new crops and transportation to non-growing regions. Regional Drop in Production: Tamil Nadu, Gujarat, and Chhattisgarh witnessed a 20% drop in tomato production, exacerbating the shortage. Impacts of High Tomato Prices: Inflationary Pressures: The volatility of tomato prices has historically contributed to overall inflation levels in the country, affecting consumers' purchasing power. CPI Impact: Tomato's price fluctuations have significant implications for the Consumer Price Index (CPI), making it a challenge for policymakers to control inflation. Economic Distress: The high prices put a strain on households' budgets, especially for low-income families heavily reliant on tomatoes as a dietary staple. Possible Solutions for Reducing Tomato Prices: Improve Value and Supply Chains: Enhance value and supply chains to address perishability and transportation issues. Increase Processing Capacity: Convert tomatoes into paste and puree during peak seasons to ensure adequate supply during lean periods. Encourage Direct Sales: Promote direct sales by Farmer Producers Organizations to provide farmers with a larger share of consumer prices. Promote Cultivation in Poly Houses and Greenhouses: Encourage cultivation in controlled environments to control pest attacks and increase yields. Why is the Inflation Rate for Tomatoes Negative? High Base Effect: The negative inflation rate is a result of a high base effect. The index value for tomatoes in June 2022 was significantly higher due to soaring prices at that time. In June 2023, despite a spike in prices, the index value was much lower compared to the previous year, leading to negative inflation. Calculation Method: In India, the inflation rate is calculated on a year-on-year basis, comparing the index value for a specific month to the same month in the previous year. The index value for June 2023 (191) is significantly lower than the index value for June 2022 (293), showing a 35% decrease. The decline in index value from June 2022 to June 2023 led to negative inflation, despite a recent increase in tomato prices. Temporary Price Surge: Tomato prices experienced a rapid increase within a short period, reaching Rs 100 per kg in June 2023. However, this surge was not sustained, and prices began to decline afterward, contributing to the negative inflation rate. Governance
