Emphasizing the current manual nature of crop area and production estimation, the Central Government has urged states and Union Territories (UTs) to transition to a digital approach by implementing the Digital Crop Survey System starting in July next year.

About the Digital Crop Survey:

• As a part of the Digital Crop Survey initiative, the Ministry of Agriculture and Farmers Welfare (MoA&FW) has instructed states to capture data on essential parameters, encompassing:
• Village name, year, season, farmer ID, farm ID,
• Crop name (at the farm plot level),
• Crop variety,
• Crop sown area (at the farm plot level),
• Geotags of crop photos,
• Geotags of the farm boundary where the crop is cultivated,
• Sowing/planting date (at the farm plot level),
• Irrigation type (at the farm plot level), and
• Irrigation source (at the farm plot level).
• This directive follows the introduction of a pilot Digital Crop Survey across multiple states earlier this year.
• In a parallel initiative, the MoA&FW has also revised the release timelines for crop estimates.
• Previously conducted in five phases, the ministry has streamlined the process by eliminating the fourth phase traditionally released in August.
• The ministry now plans to unveil comprehensive final estimates encompassing all states and seasons (kharif, rabi, summer) in September-October, departing from the earlier practice of releasing final estimates in February of the subsequent year.

Guidelines for the Digital Crop Survey:

• According to sources, the Economics, Statistics and Evaluation Division (ESED) under the Ministry of Agriculture and Farmers’ Welfare (MoA&FW), has finalised the guidelines.
• According to the guidelines, all states/ UTs shall automate/digitise the process of area enumeration/girdawari of crops at field level, i.e., Digital Crop Survey, from 2024-25 Agricultural Year.
• In India, the agriculture year begins in July and ends in June, the following year.
• Under the guidelines, states and UTs shall use GPS-enabled mobile applications for collecting crop-sown data of each plot for each season and share the village-level aggregated data with DA&FW through API only.

Need for the Digital Crop Survey:

• The current methodology for gathering and consolidating crop statistics relies entirely on manual processes across most states, leading to delays and human errors in the data compilation.
• Only a handful of states, such as Karnataka, Telangana, and Andhra Pradesh, have embraced a digital approach to data collection through GPS-enabled mobile applications, particularly for the recording of crop area and Collection of Cost of Cultivation and Equipment Survey (CCEs) data directly from the fields.
• While Maharashtra and Madhya Pradesh have implemented digital systems, they are primarily focused on recording crop areas.
• India faces a challenge due to the lack of dependable agricultural production estimates, accentuating the necessity for a "real-time assessment estimate" of crops.
• Recognizing this gap, there is a compelling need to modernize the current production estimation system by incorporating technological interventions.

A hailstorm in the evening caused massive damage to the crops and fruits in south Kashmir’s Kulgam and Shopian districts. Residents said the hailstorm damaged the apple fruit which was ready for harvesting.

What are Hailstorms?

• Hail, a solid form of rain composed of ice balls or lumps, leads to the formation of hailstorms when they descend to the ground.
• Typically lasting around 15 minutes, these storms can inflict injuries and damage to structures, vehicles, and more, particularly prevalent in midlatitude regions.
• Hailstorms occasionally coincide with other severe weather phenomena such as cyclones and tornadoes.
• The size of hailstones varies widely, ranging from small pellets under 1/4 inch to larger stones measuring several inches in diameter.
• Conditions: Conditions conducive to hailstorm occurrence involve the presence of highly developed Cumulonimbus clouds, massive anvil-shaped formations observed during thunderstorms that can reach heights of up to 65,000 feet.
• Strong updrafts, or ascending air currents within these clouds, and high concentrations of supercooled liquid water are essential elements.
• Formation of Hail: Hail formation begins with a water droplet lifted by an updraft inside a thundercloud.
• As it ascends, supercooled water droplets adhere to its surface, creating layers of ice.
• With continued ascent, the hail embryo grows by accumulating more supercooled particles until gravity pulls it down.
• Large hailstones often display alternating layers of clear and opaque ice due to irregular rates of freezing during their development.

India ranks 111 out of a total of 125 countries in the Global Hunger Index (GHI) 2023, with its progress against hunger nearly halted since 2015, reflecting a global trend.

Key Findings of Global Hunger Index (GHI) 2023:

• India holds a Global Hunger Index score of 28.7 on a 100-point scale, categorizing its severity of hunger as "serious."
• The global GHI score for 2023 is 18.3, considered moderate.
• Latin America and the Caribbean stand out as the only region in the world where GHI scores have deteriorated between 2015 and 2023.
• South Asia and Africa South of the Sahara emerge as the global regions with the highest hunger levels, each having GHI scores of 27.0.

About the Global Hunger Index:

• The Global Hunger Index (GHI) is a tool designed to comprehensively measure and track hunger at global, regional, and national levels, reflecting multiple dimensions of hunger over time.
• The GHI is intended to raise awareness and understanding of the struggle against hunger, provide a way to compare levels of hunger between countries and regions and call attention to those areas of the world where hunger levels are highest and where the need for additional efforts to eliminate hunger is greatest.
• It is prepared jointly by Irish aid agency Concern Worldwide and the German organisation Welt Hunger Hilfe.
• How the GHI Is Calculated?
• Each country’s GHI score is calculated based on a formula that combines four indicators that together capture the multidimensional nature of hunger:
• Undernourishment: the share of the population whose caloric intake is insufficient;
• Child stunting: the share of children under the age of 5 who have low height for their age, reflecting chronic undernutrition;
• Child wasting: the share of children under the age of five who have low weight for their height, reflecting acute undernutrition; and
• Child mortality: the share of children who die before their 5th birthday, reflecting in part the fatal mix of inadequate nutrition and unhealthy environments.
• The indicators included in the GHI formula reflect caloric deficiencies as well as poor nutrition.
• The undernourishment indicator captures the food access situation of the population as a whole, while the indicators specific to children reflect the nutrition status within a particularly vulnerable subset of the population for whom a lack of dietary energy, protein, and/or micronutrients (essential vitamins and minerals) leads to a high risk of illness, poor physical and cognitive development, and death.
• The inclusion of both child wasting and child stunting allows the GHI to document both acute and chronic undernutrition.

Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean.

About Pontus Tectonic Plate:

• Recently discovered in the west Pacific Ocean, the Pontus Tectonic Plate is a long-lost geological plate that holds significance in Earth's history.
• Believed to have measured about 15 million square miles at its zenith, roughly equivalent to one-quarter of the Pacific Ocean, this massive tectonic plate dates back as far as 160 million years, with more recent traces extending to approximately 20 million years ago.
• Over millions of years, the Pontus Plate underwent a gradual subduction process, pulled downward beneath a neighbouring plate by the force of gravity.

How was this Discovery Made?

• The subducting process involves the plate sinking into Earth's mantle due to its higher density compared to the surrounding mantle.
• Traces of a subducted plate are discernible in the form of rock fragments concealed in mountain belts.
• During subduction, upper portions of the plate are occasionally scraped off.
• Researchers employed geological data and computer modelling to reconstruct the movements of current plates, revealing a substantial area potentially vacated by the subducted Pontus Plate.
• Utilizing magnetic techniques, scientists identified basalt remnants in Borneo as Pontus relics, suggesting that this fragmentary evidence was left behind during the plate's subduction some 85 million years ago.

What is Plate Tectonics?

• Tectonic plates are large, rigid pieces of Earth's lithosphere, the outer shell comprising the crust and uppermost part of the mantle.
• These plates, which vary in size and shape, constantly move and interact, shaping the Earth's dynamic surface.
• The Earth's lithosphere is divided into several major plates, such as the Pacific, North American, and Eurasian plates, among others.
• The interactions at plate boundaries result in various geological phenomena, including earthquakes, volcanic eruptions, and the formation of mountain ranges.
• Plate tectonics, the theory explaining these movements, underscores how heat-driven convective currents in the Earth's mantle cause plates to diverge, converge, or slide past each other.
• Tectonic plate movements influence the planet's topography, seismic activity, and the distribution of continents and oceans, playing a fundamental role in Earth's geological evolution.

Scientists at the Indian Institute of Science's Materials Research Centre (MRC) have recently created a novel enzyme mimic known as NanoPtA.

About NanoPtA:

• The research team at the Materials Research Centre (MRC), Indian Institute of Science (IISc), has created a unique platinum-based nanozyme called NanoPtA.
• This nanozyme can be turned into a powder for use in industries.                                                                                                                                                                                                        
• When NanoPtA encounters wastewater, the molecule's benzene rings and long alkyl chains engage in multiple non-covalent interactions.
• Individual NanoPtA molecules link together to form tape-like structures that emit light, which is the source of its oxidizing capability.
• In the presence of sunlight, this nanozyme can break down pollutants in wastewater, reducing its toxicity.
• Remarkably, the nanozyme can rapidly degrade even small amounts of common contaminants like phenols and dyes (micromolar levels) within ten minutes when exposed to sunlight.
• The researchers also observed that the NanoPtA complex remained stable for up to 75 days at room temperature.

Applications:

• Besides wastewater treatment, this nanozyme could find applications in healthcare and serve as a valuable diagnostic tool for neurological and neurodegenerative diseases.
