When several farmers merge plots into a single "project farm", they use digital tools to make that teamwork far more effective. GPS mapping, drones, and in-field sensors build a live, shared picture of soil types, weather shifts, and plant growth. Because everyone works on the same data, the team can settle seeding dates, determine when to spray, and track machinery in real time. What once depended on guesswork is now driven by verifiable information.

With GPS technology, farmers can accurately map out their fields and create customised planting plans. Seeding machines change their rate on the fly, drones spray pests on targeted zones, and smart spreaders apply fertiliser only where data shows a need. Because inputs go exactly where they help, fields yield more while chemical runoff falls. Trials report considerable savings on seed, fuel, and sprays – benefits the partners split at the season's end.

Water management is just as precise. Specialised equipment tracks moisture every hour, and forecast apps predict rain, wind, or heatwaves. Automated pumps deliver measured water amounts to thirsty zones and stop when a storm is coming, slashing waste and energy bills. The result is steadier yields in dry years, fewer nutrients washed away, and a smaller water footprint for the whole partnership. Smart irrigation also helps limit weed growth, reducing herbicide use.

The journey from field to market is equally digital. Cloud platforms record harvest weights, storage temperatures, and shipment times the moment they change, while blockchain records freeze each entry so customers can rely on it. Analytic tools browse the records to indicate weak points in the procedure, forecast prices, and suggest better planting plans for the next season to project partners. This makes project farming both profitable and sustainable.

Have you ever tried playing the kind of video games that your parents played? Over the last few years, the Museum of Science in Manchester has held an exhibition which invites visitors to do exactly that. It offers them the chance to play games from the last 40 years, in various sessions throughout the day. These video games sessions have now become one of the main attractions of the museum. They are full of people playing a wide range of games every day. However, visitors often choose the ones they are familiar with. For example, parents will choose the games they used to play in their childhood. There’s also an educational purpose to the games. For instance, some old types of computers, dating back 40 years, are also available. They were originally employed in classrooms to teach pupils to write their own computer programs. Now, the museum is holding workshops encouraging children to learn similar skills - and they’re still very popular. The sessions are also seen as social events, as people discover how much fun it is to play video games with other family members. And there’s also an area called Power Up! where a number of visitors can enjoy playing the same game together. However, through the exhibition, the organisers also aim to show that video gaming is an important industry that employs many skilled people. People who enjoy gaming will also understand all the hard work, talent, and imagination that go into creating these amazing games.

If you walk into the streets and see someone throwing a plastic bottle on the ground, you’ll probably get annoyed. But do we react in the same way when we see people throwing rubbish into the sea? We all know how rubbish ruins the environment on land, but we often forget the influence that it can have on environments like the sea, lakes and rivers, too. First of all, water pollution looks terrible. Many beautiful beaches can become covered in rubbish when whatever we have thrown into the water comes ashore. Even rivers and lakes have some plastic bags and bottles floating in them. Secondly, rubbish can hurt animals and birds that live in or by the water. If they see a plastic bottle, they may think it is food. However, when they try and eat the bottle, it can get caught in their mouth or stomach and stop them from eating anything else. Plastic bottles can also stop dolphins from breathing. Sometimes, fishing boats leave bits of fishing net behind in the water. Fish can get caught in these and die. Finally, people forget that plastics contain chemicals that stay in the water. This is very bad for both fish and plants. If you eat fish containing these chemicals, then you can also get ill. In conclusion, we need to worry about water pollution as much as we care about land or air. We should all protect the seas, lakes and rivers, and remember to take our rubbish away with us.

The Japanese love inventing and they are very good at it. But there is one inventor who has invented more things than anyone else in Japan - Dr. Nakamats. He has designed over 4,000 new inventions over the last fifty years. He is most well-known for his unusual inventions. He designed many strange things such as glasses which look like eyes so you can’t notice them, shoes which have steel springs so that you can jump in them, and a pillow which stops you from falling asleep when you are driving. How does he come up with these ideas? He finds listening to Beethoven helpful. But the thing that makes him most creative is holding his breath underwater. He dives into his swimming pool every day and stays underwater as long as he can. He believes that less oxygen in the brain is good for new ideas. He also dives with a pencil and a notebook which he invented. He needs to write down his ideas immediately in the water because they disappear quickly. Dr. Nakamats believes that eating the right food is important for creativity, and he has invented some snacks that he says are good for your brain. He has also invented an armchair which helps to enhance your brainpower. He sits in the chair every day to give him more good ideas. Dr. Nakamats is now in his eighties, but he plans to live until he is 144 years old, so he still has plenty of time to develop even more new ideas.

Action movies are exciting and a lot of fun to watch, but they also involve scenes of great risk and danger. In the language of filmmaking, dangerous actions are called stunts. Who performs these stunts? This work is too dangerous for regular actors. Movie companies usually hire special stunt people to stand in for the actors in scenes that are unsafe. Movie producers don't like to let actors do their own stunt work. If the actors injure themselves, it can delay the production schedule. Using stunt people also saves time. Most stunt people have years of experience, which enables them to perform their stunts with a minimum of risk. It would take too long to train the actors to perform dangerous scenes safely. Some people who love the thrill of dangerous sports such as skydiving or rock climbing think it would be easy to work as a stunt person. But it isn’t enough to be a risk-taker. Stunt performers also have to know what to do if anything goes wrong. In addition to risk-taking and meticulous attention to detail and planning, stunt work requires being in top physical condition. Although there are a few training programmes for stunt performers, most provide only an overview of the profession. Normally, the people who attend these programmes already have experience in dangerous sports, rescue work, or the military. So the best way to prepare for a career in stunt work is to train in an area that involves strong physical conditioning and has an element of physical danger. Modern filmmaking techniques have changed the way some dangerous scenes are filmed. For example, computer-generated images make it possible to show stunts that would be too dangerous or expensive for real stunt people to perform. Computer-generated images are often used today to create big fight scenes, car crashes, and explosions. However, they are not always the best choice. Many audiences want to see real people perform actual stunts. Also, the rising popularity of made-for-TV movies around the world ensures that there is still plenty for stunt people in the film industry.

Device-centred communication has become almost universal over the past twenty years. More than three quarters of people in the world now own a mobile device, and more than half communicate via social networking. It is now hard to imagine a world without mobile devices consisting of such things as mobile phones, laptops and tablets. They allow us to stay in touch with a large network of friends, no matter where they are. But many experts say that communicating with a device is nothing like talking with someone in person. “Body language, eye contact and tone of voice can tell us so much,” psychologist Mary Peters says. “And none of those exist on a device. Even video chat removes many subtle clues.” We don’t know to what extent these technologies will permanently change the way people interact. People will always want to meet up with others in small and large groups. Indeed, it is fair to say that social media makes it easier than ever before for people to organise social events. However, there is still a danger that device-centred communication may have a negative long-term impact on the way people interact with each other on a day-to-day basis. We must not, therefore, lose sight of the need to focus on the actual people around us, and remember that they deserve our real – not virtual – attention. The idea of a culture where people always have a screen between them sounds a bit funny, because deep understanding comes when we see the reactions on other people’s faces.

The concept of traffic-free shopping areas goes back a long time. During the Middle Ages, traffic-free shopping areas were built in Middle Eastern countries to allow people to shop in comfort and, more importantly, safety. As far back as 2000 years ago, road traffic was banned from central Rome during the day to allow for the free movement of pedestrians. The modern, traffic-free shopping street was born in Europe in the 1960s, when both city populations and car ownership increased rapidly. Dirty exhaust from cars and the risks involved in crossing the road were beginning to make shopping an unpleasant and dangerous experience. Many believed the time was right for experimenting with car-free streets, and shopping areas seemed the best place to start. At first, there was resistance from shopkeepers. They argued that people would avoid streets if they were unable to get to them in their cars. When the first streets in Europe were closed to traffic, there were even noisy demonstrations, as many shopkeepers predicted they would lose customers. With the arrival of the traffic-free shopping street, many shops, especially those selling things like clothes, food and smaller luxury items, prospered. Unfortunately, shops selling furniture and larger electrical appliances actually saw their sales drop. Many of these were forced to move elsewhere, away from the city centre.

Machines already perform a lot of tasks that were usually done by humans, such as building cars, doing complex calculations, and even marking exam papers. But now it seems that ever more intelligent machines are straying into areas where we never envisaged they would go. We have always taken pride in having a unique kind of intelligence that machines could never match, one which allows us to think of new ideas and produce creative and artistic works. But it seems that even here, computers are lining up to compete with us. Machines can easily be trained to do the physical work of producing art. About ten years ago, a painting robot known as e-David was created at a university in Germany. And recently in New York, the painting ‘Portrait of Edmond de Belamy’ has been auctioned for nearly half a million dollars. What made it a bit unusual was that the idea, and the image itself, was produced entirely by a computer. A group of young French artists gave instructions to the computer, aiming simply to show that computers can be creative. Some artists are now working with computers to produce a new kind of art. Computer-generated works of art are certainly interesting, and make us think about the limits of what machines can and cannot do. But not everyone would accept that they qualify as art. Some enthusiasts would argue they do, and the collectors willing to pay high prices for these works would suggest there is definitely a market for computer art. Others, however, would disagree. Many ‘real’ artists would claim that art is an expression of human intelligence and human emotions. More importantly, it is about a desire to communicate with other people. These things, they argue, are part of being human and can never be produced by a machine.

Many children have music classes when they attend school. And it is thought that music can help them learn other subjects better. Research has shown that it can improve children’s performances in certain subjects. Some studies have shown that music training can help you understand your own language better. It could also help you with learning a second one. Moreover, young people who have studied music also seem to get higher scores in other subjects like maths. So it could be that these school subjects are connected in some way. Music also helps you think of new ideas, and believe more in yourself. If you are learning the guitar, for example, it can be really exciting when you are able to start composing your own pieces of music. One of the biggest benefits, of course, is that listening to music can reduce your stress. And composing music can make you feel the same way. Maybe your musical knowledge will even open up a great career path for you in the future!

Since the 19th century, companies have looked for better and cleaner ways of creating electricity. One UK company has created a special type of floor made of square tiles. Under each square, there is a system that can create electricity very cheaply when someone steps on it! The design of the floor works very well when it is used in very busy areas. And the reason is that a lot of energy is created simply because of the large numbers of people walking across the floor. The floor can have other uses too; one of them is to record how many people visit a shopping centre. This kind of information is very useful for shop owners because very often they want to know at which times of days they have the highest numbers of customers. So the next time you visit a big shopping centre, have a careful look at the floor that you are walking across!

Staying in hotels and resorts has been a traditional part of travel since the beginning of mass tourism. But nowadays, many tourists want a more intimate experience. For this reason, they are choosing to 'go native'. This often means staying in the kinds of places that local people inhabit. In big cities, you can try staying with the friend of a friend. You may end up sleeping on the couch or the floor, but the advantages outweigh the discomfort. The biggest plus is that you'll be staying with a local and seeing the city from a local perspective. Another option is house-swapping. Several websites allow you to connect with people who want to trade living situations. It's usual to exchange emails about favourite places in the city before the swap, meaning you can have a truly local experience. But of course, you can only do this if you don't mind having strangers staying in your house. For the more adventurous, staying in a native structure in an African village or a hut on the water in Vietnam or Thailand can be real thrill. These might not even include plumbing or electricity, and that is part of the charm. The experience of dealing with oil lamps and carrying water really gives you a sense of how the people live. No matter how unadventurous you feel, you might want to consider crossing hotels off your list. Getting to know the local way of life is the most valuable part of travel. And what better way is there to do this than staying where the local people actually live?

Norwich is the capital of East Anglia, an area on the east coast of England which is famous for its natural beauty and impressive architecture. Norwich is a wonderful city to explore and is popular with tourists all year round. Norwich is not a city of luxurious hotels, but it has a good selection of reasonably priced places to stay in, both in the city centre and further out. The Beeches Hotel, for example, next to the cathedral, has a beautiful Victorian garden. Comfortable accommodations costs £65 for two nights' bed and breakfast per person. Norwich is famous for its magnificent cathedral. The cathedral has a summer programme of music and events which is open to the general public. One event, “Fire from heaven”, is a drama and musical performance with fireworks, a laser light show and a carnival with local people dressed in colourful costumes. Norwich is also home to the Sainsbury Centre for Visual Arts, a world-class collection of international art in a building at the University of East Anglia. This is well worth a visit and there is a lovely canteen with an excellent selection of hot and cold snacks. It also specializes in vegetarian food. In addition, the city has a new professional theatre, the Playhouse, on the River Wensum. The city' annual international arts festival is from 10 to 20 October. Finally, if you fancy a complete break from the stresses of everyday life, you could hire a boat and spend a few days cruising along the river of the famous Norfolk Broads National Park. In our environmentally friendly age, the emphasis has moved forwards the quiet enjoyment of nature and wildlife. You can buy hire a boat, big or small, for an hour or two or even up to a week or two. This makes a perfect day out or holiday for people of all ages.

The United Nations recently outlined the extent of the global water crisis, saying that 2.7 billion people would face severe water shortages by 2025 if consumption continues at current rates. Today, an estimated 1.2 billion people drink unclean water, and about 2.5 billion lack proper toilets or waste disposal systems. More than five million people die each year from diseases related to unclean water. Humans are pumping water out of the ground faster than it can be replenished. In this difficult situation, a water conservationist, Neil MacLeod in South Africa, has found innovative ways to improve his local water situation. Neil MacLeod took over as head of Durban Metro Water Services in 1992. The situation he found was a catastrophe. Durban had one million people living in the city and another 1.5 million people who lived in poverty just outside it. The entire city was rife with broken water pipes, leaky toilets, and faulty plumbing whereby 42 percent of the region's water was simply being wasted. MacLeod's crews began repairing and replacing water pipes. They put water meters on residences, replaced eight-litter toilets with four-litter models, and changed wasteful showers and water taps. To ensure that the poor would receive a basic supply of water, MacLeod installed tanks in homes and apartments to provide 190 liters of water a day free to each household. Water consumption in Durban is now less than it was in 1996, even as 800,000 more people have received service. Through sensible water use, Durban's conservation measures paid for themselves within a year. No new reservoirs will be needed in the coming decades, despite the expected addition of about 300,000 inhabitants. MacLeod has also turned to water recycling. At the water recycling plant, wastewater is turned into clean water in just 12 hours. Most people are unable to discern a difference between the usual city drinking water and the treated wastewater, although it is actually intended for industrial purposes. Some people still hope that new technology, such as the desalination of seawater, will solve the world's water problems. “But the fact is, water conservation is where the big gains are to be made,” says Sandra Postel of the Global Water Policy Project. The dedication and resourcefulness of people like Neil MacLeod offer inspiration for implementing timely and lasting solutions to the world's water concern.
