Karnataka State leads in geotagging lakes
Jointly initiated in March 2024 by the departments of Minor Irrigation, Groundwater Development, and SSLR (Survey, Settlement and Land Records), the project aims to digitally map 41,857 water sources using drones, high-resolution satellite imagery, and ground verification.
As of April 2025, 34,651 lakes covering 7.7 lakh acres have been surveyed. The data revealed that 42,678 acres of lake area and buffer zones have been encroached upon. Authorities have reclaimed 28,750 acres for public use.
SSLR officials said digital mapping has provided strong evidence to identify and act on illegal encroachments. The use of GPS and satellite data enables swift legal intervention and preservation of public land.
Drone surveys have covered 8,433 lakes, with another 6,210 expected by year-end. Real-time data is now available on a Web-GIS platform accessible to government departments, and plans are underway to make it public.

The story of the World Wide Web
Imagine waking up in a world where you couldn't message your friends, watch puppy videos, look up homework help, or play games with someone living across the globe. Hard to picture, right? Yet, only a few decades ago, none of this was possible—there were no memes, no viral dances, no endless scrolling. All of these wonders exist thanks to something we use every day but rarely stop to think about: the World Wide Web. Let's rewind to the late 1980s. Computers did exist, but they were like islands in the middle of a huge ocean. You could use one computer to create documents or play simple games, but it was tough to connect with anyone outside your own home or school. If you wanted to send a message, you might use something called 'email' if you were very lucky—or you just wrote a letter! Then, in 1989, a scientist named Tim Berners-Lee, working at a place called CERN in Switzerland, came up with a brilliant idea. What if we could link information on different computers, using a network that anyone, anywhere, could access? His idea was the start of the World Wide Web. At first, only a handful of scientists and researchers used the Web, sharing information about their experiments. The first website was nothing flashy—it mostly had text and links to other pages, like a super-basic online noticeboard. But this idea—of clicking from one page to another, from one website to the next—changed everything. Soon, the Web began to spread. More and more people started building websites, and before long, anyone with a computer (and a very loud, slow modem) could surf the Web from home. You might wonder what makes the Web so different from the 'internet.' Here's a secret: the internet is the giant network that connects millions of computers around the world, like invisible wires running under oceans and across countries. The World Wide Web is just one way to use the internet, like a magical library that lets you hop from one book to another just by clicking your mouse. Thanks to the Web, you can send messages, upload videos, do research, and watch funny cats—all by following hyperlinks. In the early days, web pages looked quite plain, with simple colours and blocky text. There were no likes, no comments, and definitely no emojis. People would use something called 'dial-up,' which made a weird screeching noise every time you connected. It could take five minutes just to load a single picture! Even so, it was astonishing. For the first time, you could discover new ideas, read the news from faraway countries, or join a chatroom to meet people with the same hobbies—even if you lived on opposite sides of the planet. As more people came online, the Web became an exciting, bustling place. New inventions kept popping up—search engines like Google helped you find anything in seconds. Social media sites let you share photos and videos with friends. Online games meant you could battle, build, or team up with people you'd never met in real life. The Web wasn't just about finding information anymore; it became a space for sharing, creating, and having fun. Of course, it's not all fun and games. Just like in the real world, the Web has its tricky spots—spam, fake news, cyberbullies, and scams. That's why it's important to use your 'digital common sense,' the way you look both ways before crossing a road. Stick to safe sites, never share private information, and always ask a trusted adult if something seems weird or makes you uncomfortable. There's loads of good out there, but a little caution keeps the Web a safe place to explore. One of the most amazing things about the Web is that it belongs to everyone. Unlike a theme park or private club, you don't have to buy a ticket or get special permission to join. Anyone, anywhere in the world, can build a website, share their story, or start a movement. People use the Web to learn languages, raise money for good causes, or even organise protests and change the world. During the Covid-19 pandemic, it was the Web that kept schools, families, and friends connected—even when everyone was stuck at home. If you're curious about how the Web works, you're not alone. Many teens today are learning to code websites and apps, becoming digital creators, not just users. The programming languages that power the Web—like HTML, CSS, and JavaScript—are like the building blocks of your favourite games and websites. If you can dream it, there's a good chance you can build it, too!

Karnataka State leads in geotagging lakes
Bengaluru: In a major step toward sustainable water management, the government has launched a geotagging and digital mapping initiative to document and reclaim encroached lakes and water sources across the state. So far, over 31,000 lakes and water bodies have been geotagged, making Karnataka the first in India to adopt satellite and drone-based lake governance on this scale. Jointly initiated in March 2024 by the departments of Minor Irrigation, Groundwater Development, and SSLR (Survey, Settlement and Land Records), the project aims to digitally map 41,857 water sources using drones, high-resolution satellite imagery, and ground verification. As of April 2025, 34,651 lakes covering 7.7 lakh acres have been surveyed. The data revealed that 42,678 acres of lake area and buffer zones have been encroached upon.

State charts roadmap to become India's quantum capital
Bengaluru: In a major stride towards emerging as India's hub for next-generation science and technology, Karnataka has unveiled its ambition to become the country's 'Quantum Capital.' The announcement was made by Minister for Minor Irrigation, Science and Technology, Shri N.S. Boseraju, ahead of the prestigious Quantum India Bengaluru Summit that will host Nobel Laureates and leading global experts in the field. Speaking at a preparatory meeting at Vikasa Soudha, the minister said, 'Under the visionary leadership of Chief Minister Shri Siddaramaiah and Deputy Chief Minister Shri D.K. Shivakumar, our government is laying the groundwork to position Karnataka as India's Quantum Capital. This dialogue with Nobel Laureates marks the beginning of a long-term roadmap to integrate quantum innovation into Karnataka's development blueprint.' Karnataka, with Bengaluru as its innovation epicentre, is already home to a thriving ecosystem spanning information technology, aerospace, and biotechnology. With this initiative, the state is aiming to push the frontiers further by building infrastructure and fostering collaborations in quantum computing and related technologies. The summit will feature high-level interactions between Nobel Laureates and senior government officials, including Principal Secretaries of the Departments of Industries, IT & BT, and Higher Education. These discussions are expected to shape policy direction, accelerate research initiatives, and enable international partnerships in the quantum domain. Officials, including Sadashiva Prabhu, Managing Director of Karnataka Science and Technology Promotion Society (KSTePS), and Prof. Akshay Naik from the Indian Institute of Science (IISc), who also serves as co-chair of the summit, were present during the meeting. The Quantum India Bengaluru Summit is being viewed as a landmark event that places Karnataka at the forefront of India's quantum revolution while also signalling its global aspirations in deep-tech innovation.
